System Description Chapter Overview • • • This chapter provides: an overview of the FieldMonitor Machinery Protection System a description of the components of the system the basics of Flexbus communication 1.1 System Overview The FieldMonitor system is a distributed vibration monitor system that physically and functionally integrates with distributed I/O, programmable logic controllers, distributed control systems, and PCbased control systems. The system is used with the Allen-Bradley Flex I/O or Flex Ex distributed I/O products and communicates over industry standard networks using Allen-Bradley and third-party Flex I/O network adapters or Flex Ex serial bus isolator and network adapters. A distributed vibration protection system is an alternative to larger rack-based systems or vibration transmitters when… • the vibration protection system integrates with a machine control system that uses distributed I/O over appropriate networks, • vibration parameters display on the Human Machine Interface (HMI) for the machine control system, • you want local, “on-skid” mounting, • it is more efficient and economical to connect vibration points to a distributed FieldMonitor systems than to wire all points to a central rack-based system, • the application can benefit from proper connectivity to diagnostic and machinery management systems, reduction or elimination of field wiring, and the integrity and robustness of a system possessing self-check and self-contained alarm capabilities, or • protection over a network is acceptable. 1 FieldMonitor Machinery Protection System Operation Manual Distributed vibration monitoring saves money by reducing installation and wiring costs in the following ways: • smaller footprint reduces cabinet space and enclosure size • “on-skid” mounting and internal Proximitor modules eliminate field wiring and reduce the number of housings • a network cable may be the only wiring necessary between a central control room and the machine • machine OEMs and packagers who use modular manufacturing techniques can reduce cost by completely installing, wiring, and testing the vibration system • break down consists of disconnecting the network cable and power thereby leaving the vibration system intact and eliminating expensive field wiring and troubleshooting • the 1701/06 Isolator Terminal Base (ITB) uses internal galvanically isolated safety barriers which eliminate the need for external safety barriers and an Intrinsically Safe Earth connection. FieldMonitor systems are nodes on a field bus network. Each node consists of an Allen-Bradley or third-party Flex network adapter, a number of Flex modules depending on the application, and the Bently Nevada FieldMonitor system. The Flex network adaptors support a continually expanding variety of networks. Some examples are: • • • • • • • ControlNet Remote I/O DeviceNet™ adapters Profibus™ DP Modbus® adapters Interbus S Ethernet TCP/IP Appendix F lists the Flex network adapters that Bently Nevada has tested with the FieldMonitor system. 2 Section 1 - System Description This manual does not cover selection, layout, installation, and configuration of the network. There are two types of FieldMonitor systems, each of which uses a different terminal base. Terminal bases are the mounting platform and wiring termination point for the FieldMonitor system. The 1701/05 Terminal Base (TB) is used for most applications that do not require intrinsic safety and the 1701/06 Isolator Terminal Base (ITB) is used for applications that do require intrinsic safety. 3 FieldMonitor Machinery Protection System Operation Manual FieldMonitor System Overview Flex modules Each FieldMonitor System consists of the following components: • • • • • • • • 4 a terminal base a power supply an optional FieldMonitor Management Interface Module (FMIM) communication processor that provides the monitor information to a host computer an optional Keyphasor Module (an internal Proximitor module or a transducer I/O module that interfaces to an external Proximitor sensor, the 1701 system supports only one Keyphasor transducer per terminal base) monitor modules transducer I/O modules internal galvanic isolators (only with the 1701/06 Isolator Terminal Base) transducers Section 1 - System Description FieldMonitor Product Overview using the 1701/05 Terminal Base FieldMonitor Product Overview using the 1701/06 Isolator Terminal Base: The network adapter manages communication between other devices on the network and the 1701 modules installed in the 1701 terminal base. The adapter communicates with the1701 modules over Flexbus, the Flex I/O backplane bus. The four monitor slots are addressable by Flexbus. 5 FieldMonitor Machinery Protection System Operation Manual 1.2 System Components The components of the FieldMonitor system are described in the table below.

This software also provides a convenient Windows user interface that allows you to select configuration choices from menus and to go online to monitor values. If you are using FieldMonitor configuration software then the information in Chapter 7 and Appendices A, B, C, and D is for reference only. If you cannot use FieldMonitor configuration software then you must use your PLC software to build the data table for each monitor from the information in the manual sections mentioned above. Available FieldMonitor configuration software is: Part Description 1701/01 FieldMonitor Configuration Software for RSLogix5. FieldMonitor Configuration Software for RSLogix5000. 1701/02 6 Section 1 - System Description 1.2.2 About the 1701/05 Terminal Base (TB) and the 1701/06 Isolator Terminal Base (ITB) The 1701/05 Terminal Base is suitable for all applications where transducers are installed in non-hazardous, Division 2, or Zone 2 areas. The 1701/05 Terminal Base can also be used with external safety barriers. The 1701/06 Isolator Terminal Base (ITB) is required for applications where intrinsically safe transducers are installed in Division 1 or Zone 0/1 hazardous areas. The 1701/06 ensures intrinsic safety by using a galvanically isolated safety barrier (isolator) that is installed directly into the ITB. The terminal base provides: • the mounting platform for the system • slots for up to four monitors allowing up to 8 channels of monitoring • slots for up to four internal or external transducer I/O modules (one required for each monitor) • slots for up to four isolators (1701/06 ITB only, (one required for each transducer I/O module) • an FMIM slot • a Keyphasor slot (one Keyphasor module per terminal base, channel A only) • the power supply slot • I/O terminations • the Flexbus connection • 9 coaxial connectors for buffered dynamic signals from the 8 monitor channels and the Keyphasor output • a dynamic connector to connect the 8 buffered dynamic signals to a “patch panel” for easy diagnostic access. 7 FieldMonitor Machinery Protection System Operation Manual 1701/05 Terminal Base plan view with modules removed When you use the 1701/05 TB, you must install monitors and transducer I/O modules or internal Proximitor modules in pairs. Field wiring termination, buffered outputs, and the Keyphasor output terminals are identified by slot number and channel, where channels are identified as A or B. • Install monitors in numbered slots with their associated I/O or internal Proximitor module in the corresponding adjacent slot preceded by a “T”. For example, a monitor in slot 2 has its associated I/O in slot T2. • Install monitors in slots 2, 3, 4, and 5. • Install transducer I/Os or internal transducers used with monitors in slots T2, T3, T4, and T5. • Install the FMIM in slot 1K. • Install an internal Proximitor sensor or transducer I/O module for the TB’s single Keyphasor transducer in slot T1K. • If an internal transducer module such as a dual Proximitor module is used, connect the proximity probe cables to the connectors on the top of the internal transducer module rather than to the I/O terminals on the terminal base. 8 Section 1 - System Description When you use the 1701/06 ITB you must install a monitor and its associated I/O or internal Proximitor module and isolator in sets. Field wiring termination, buffered outputs, and the Keyphasor output terminals are identified by slot number and channel, where channels are identified as A or B. • Install monitors in numbered slots with their associated I/O or internal Proximitor module in the corresponding adjacent slot preceded by a “T” and the associated isolator in the “I” slot. For example, a monitor in slot 3 has its associated I/O in slot T3 and its associated isolator in slot I3. • Install monitors in slots 2, 3, 4, and 5. • Install transducer I/Os or internal transducers used with monitors in slots T2, T3, T4, and T5. • Install isolators in slots I2, I3, I4, and I5. • Install the FMIM in slot 1K. • Install an internal Proximitor sensor or transducer I/O module for the TB’s single Keyphasor transducer in slot T1K and an isolator in slot I1. • If an internal transducer module such as a dual Proximitor module is used, connect the proximity probe cables to the connectors on the top of the internal transducer module rather than to the I/O terminals on the terminal base. 9 FieldMonitor Machinery Protection System Operation Manual Connect FieldMonitor systems to Flexbus by using a direct connection or by using an extender cable to connect to the network adapter as shown below. Direct connection to the 1701/05 TB Extender cable connection to the 1701/05 TB Direct connection to the 1701/06 ITB Extender cable connection to the 1701/06 ITB 10 Section 1 - System Description MADE IN U.S.A. MA DE IN U.S .A. 1.2.3 About the Power Supply Available power supplies are: Part 1701/10 Description +24 Volt DC Input The power supply installs in the large slot in the terminal base. The supply provides logic and transducer voltages to the FieldMonitor system. 11 FieldMonitor Machinery Protection System Operation Manual 1.2.4 About Monitors Monitors digitize the input, scale the signals into a range, check for errors, determine OK status, and process alarms. Communication between the controller and the monitor consists of the controller sending configuration and setpoints to the monitor and the monitor sending vibration and status values to the controller. This communication takes place first via the network or fieldbus between the controller and the adapter and then via Flexbus between the adapter and the monitor. The controller serves as the host for the vibration system. The human machine interface (HMI) displays the vibration parameters for the controller. 12 Section 1 - System Description 1.2.5 About Transducer I/O Modules A transducer I/O module is a two-channel module which interfaces between a monitor and a transducer mounted at some other location. Some I/O modules are compatible with a family of transducer types, while others require a specific transducer. 1.2.6 About Internal Transducers 13 FieldMonitor Machinery Protection System Operation Manual An internal transducer is a transducer or sensor that installs directly into the terminal base in place of a transducer I/O module, such as a dual channel internal Proximitor module. 1.2.7 About Internal Isolators Internal Isolators are dual galvanically isolated safety barriers that plug into the 1701/06 Isolator Terminal Base (ITB). Each isolator supports two transducers and is used with internal Proximitor sensors and transducer I/O modules. There are two types of isolators. The 170190-01 is used with all supported transducers except the CEC velocity sensor. The 170190-02 is used only with the CEC velocity sensor and a velocity I/O module. 14 Section 1 - System Description 1.2.8 Compatibility of Monitors, Isolators, Internal and External I/O Modules A given monitor type can use a variety of different transducer I/O modules. The different I/O modules provide interfaces to different transducer types and may be used with several types of monitors. Available monitors are: Part Number 1701/15 Monitor Monitor Type Proximitor Input Monitor 1701/25 Seismic Input Monitor 1701/30 Dynamic Pressure Monitor Radial Vibration Thrust Position Velocity Acceleration Pressure The user programs the Proximitor Input Monitor as either a Radial Vibration or a Thrust Position Monitor and the Seismic Input Monitor as either a Velocity or Acceleration Monitor. You can configure the Dynamic Pressure Monitor either a single channel or dual channel monitor. Configuration is described in Chapter 7. Application Alert: Because 1701 monitors cannot detect what type of transducer I/O or internal transducer is installed, verify that the installed hardware matches your programmed configuration. See the 1701/30 Dynamic Pressure Monitor manual 14450401 for information on the transducers and I/Os that can be used with this monitor. 15 FieldMonitor Machinery Protection System Operation Manual You can use the 1701/15 Proximitor Input Monitor with any of the transducer I/Os or internal transducers listed in the following table: Monitor 1701/15 Proximitor Input Monitor I/O or internal transducer module part number 170133-050-xx I/O module or internal transducer module description Application Internal Dual 3300 5 metre Proximitor Module Radial vibration, axial position, or Keyphasor signals where the distance between the terminal base and the probe is 5 metres or less and the 5 m system is good for both channels.

The adapter addresses, or selects, each module by activating a hardware select line that is unique to that module. The 1701 uses the adapter to address each monitor. This means that there are four addressable slots (2, 3, 4, and 5) and that four Flex module select lines are preallocated for use by the FieldMonitor system even if no modules are installed. The Slot Offset Switch located in the power supply slot on the terminal base is used to re-map the Flex select lines. This switch should be set to the off position. NOTE: The Slot 1 Address switch was used on systems prior to introduction of FMIM. The switch has been removed from more recent versions of the terminal bases. 18 Section 2 - Receiving and Handling Instructions 2. Receiving and Handling Instructions 1701 modules, proximity probes, and extension cables are shipped separately. You must unpack and assemble or interconnect these parts at the installation site. Visually inspect each module for shipping damage when you unpack it. If shipping damage is apparent, file a claim with the carrier and submit a copy to Bently Nevada LLC. Include part numbers and serial numbers on all correspondence. Store the equipment in areas that will not expose it to a potentially damaging corrosive atmosphere or high temperature. See the specifications in Appendix E. Application Alert: Handling and storing printed circuit boards is extremely critical. Circuit boards contain devices that are susceptible to damage when exposed to electrostatic discharge. Take these precautions: • Do not discharge static electricity into the module connectors or onto circuit boards • Transport and store circuit boards in electrically conductive bags or foil • Use extra caution during dry weather. Relative humidity less than 30% will increase the level of risk to electrostatic discharge. Although the 1701 module connectors and terminals have protection against electrostatic discharge, take reasonable precautions to avoid ESD when handling the modules Application Advisory: The 1701/05 Terminal Base arrives with 2 shipping screws to prevent separation of the Terminal Base halves. These screws should be removed before installing modules Customers and third parties, who are not member states of the European Union, who are in control of the product at the end of its life or at the end of its use, are solely responsible for the proper disposal of the product. No person, firm, corporation, association or agency that is in control of product shall dispose of it in a manner that is in violation of any applicable federal, state, local or international law. Bently Nevada LLC is not responsible for the disposal of the product at the end of its life or at the end of its use. 19 Section 3 - Installation 3. Installation This chapter first discusses how to select and design the enclosure for the FieldMonitor system as follows: • European Union Directive Compliance • Enclosure design considerations • Hazardous area installation guidelines • CE installations It then covers how to install the FieldMonitor system: • mounting the terminal base • setting the slot offset switch • connecting the Flex modules • installing the power supply • installing 1701 modules • wiring the system • using external safety barriers 3.1 European Union Directive Compliance The FieldMonitor system has the CE mark and approvals for installation within the European Union and EEA regions and has been designed and tested to meet the following directives. EMC Directive A technical construction file documents that this product is tested to meet Council Directive 89/336/EEC Electromagnetic Compatibility (EMC) and the following standards, in whole or in part: • EN 50081-2EMC - Generic Emission Standard, Part 2 Industrial Environment • EN 50082-2EMC - Generic Immunity Standard, Part 2 Industrial Environment This product is intended for use in an industrial environment. Low Voltage Directive This product meets Council Directive 73/23/EEC Low Voltage when the 24 Vdc power source used for the 1701/10 power supply is approved to the Low Voltage Directive. 21 FieldMonitor Machinery Protection System Operation Manual 3.2 Enclosure Design Considerations This section shows how to verify that the FieldMonitor system will remain within its operating temperature when it is installed inside an enclosure and provides guidelines to protect against fluid ingression into the enclosure. FieldMonitor Power Dissipation Calculate the total power dissipated by a FieldMonitor system by using these formulas: Terminal Base Type Formula 1701/05 Terminal Base P170105 = [5.5 + 2.1* n + 3* p] watts 1701/06 Isolator Terminal Base P170106 = [5.5 + 2.1* n + 4.2* m + 3* p] watts where “n” is the number of monitor modules, “m” is the number of isolator modules, and “p” is equal to 1 when the FMIM is installed and equal to 0 if not installed. The initial dissipation of the 1701 is 5.5 watts for the power supply, 2.1 watts for each monitor, 3 watts for the FMIM, and 4.2 watts for each isolator. The internal Proximitor modules and I/O modules have very little effect on total power dissipation and are not used in the power calculation. Calculating the Temperature Rise in a Weather Proof Housing Application Alert: This section is only a guideline. Because the FieldMonitor system can use an unlimited number of enclosure sizes, shapes, materials, and installations, you must ensure that the system is not exposed to temperatures above or below its rating. 22 A number of factors affect the thermal rise (∆ ∆TWPH) from the inside to the outside of a weatherproof housing. The primary factors that affect ∆TWPH are the size of the enclosure, the power dissipated in the enclosure, the enclosure material, and exposure to direct sunlight. To calculate temperature rise in a weather proof housing (∆ ∆TWPH): Section 3 - Installation 1. Determine the total power dissipated inside the enclosure PWPH. You can calculate the total power dissipation of the FieldMonitor system using equations from the previous subsection on FieldMonitor Power Dissipation. For example, PWPH = P1701 + Power Dissipation of other equipment inside the same enclosure. 2. Calculate the surface area of the enclosure in square feet AWPH. Include the area of all six sides. Note: If the enclosure is mounted against a surface that does not allow heat dissipation, subtract the area of that side from the total surface area. Application Alert: ∆TWPH is an estimate of the average temperature inside the enclosure. If no air circulates inside the enclosure, there will be a large temperature gradient between the bottom and the top of the enclosure. Calculate the temperature difference between outside and inside of the enclosure as shown in the example below. You will need to determine the temperature co-efficient for your particular housing. Empirical testing has shown that the temperature rise for a specific steel housing is approximately 2.5 °C per watt per square foot. Using this information ∆TWPH can be estimated with the following expression. ∆TWPH ≈ 2.5 x PWPH AWPH where: Application Alert: Direct sunlight will greatly increase the temperature inside the enclosure. ∆TWPH = Temperature difference between outside and inside of enclosure in °C. PWPH = Total power dissipated within enclosure, in watts. AWPH = Total area of all 6 sides of enclosure, in square feet. Enclosure Oil Wicking and Humidity Considerations If proximity probes and their extension cables are located in lubrication oil lines, then it is possible for oil to “wick”, or travel, along the cable and eventually reach the Proximitor 23 FieldMonitor Machinery Protection System Operation Manual Sensor. Oil contamination of the FieldMonitor system will reduce reliability. Eliminate or reduce oil wicking by using Bently Nevada FluidLoc® probe cables, putting drip loops in cables, or installing the FieldMonitor system above the probe installation points. The FieldMonitor system and Flex I/O network adapters are rated for non-condensing humidity. Type 4 or IP64 enclosures should be used if the area will be exposed to moisture. In high humidity environments where condensation can occur inside enclosures you should take appropriate design precautions, such as using a purged housing. 3.3 Hazardous Area Installations Application Alert: The FieldMonitor system is not designed to operate in a Zone 1/Div. 1 hazardous area. If you install the 1701 Monitoring System in a hazardous area, the system must be properly labeled and you must determine if a housing is required. FieldMonitor systems that operate in hazardous areas must be marked with a label that identifies the hazardous area, for example Div. 2 or Zone 2. Install the 1701/05 Terminal Base using control drawing 139255 and the 1701/06 Isolator Terminal Base using control drawing 141265. Div. 2 Installations At a minimum, a FieldMonitor system requires a Type 4 enclosure for Div. 2 installations if the area can become dirty or wet, such as outdoors or where hose-down cleaning occurs. Application Alert: Enclosures that house the FieldMonitor systems cannot be opened or worked on if installed in a hazardous area unless appropriate procedures are followed. If you install the equipment inside a building that meets the requirements of a Type 4 enclosure, the FieldMonitor system requires no separate enclosure because the building itself acts as the enclosure. Zone 2 Installations At a minimum, a FieldMonitor system requires an IP54 enclosure for Zone 2 installations. 24 Section 3 - Installation If you install the equipment inside a building that meets the requirements of a IP54 enclosure, the FieldMonitor system requires no separate enclosure because the building itself acts as the enclosure. 3.4 CE Installations A 1701 terminal base with modules installed must be mounted inside an Electromagnetic Interference (EMI) shielded area. For high electromagnetic noise environments or CE installation, you must properly ground the FieldMonitor system, EMI shielding enclosure, and cables to provide a ground path for electromagnetic energy (see the following figures). The shielding enclosure must be metal and should have an EMI gasket. 25 FieldMonitor Machinery Protection System Operation Manual Typical Installation-1 Typical Installation-2 (1701/05 Terminal Base using external transducers is shown. Installation for a 1701/06 Isolator Terminal Base is the same) 26 Section 3 - Installation Wiring Install all wiring exiting the EMI shielding enclosure in EMI conduit and terminate cable shields to the terminal base only. Additional Notes Larger scale factors are less susceptible to EMI than smaller scale factors. Larger full-scales are less susceptible to EMI than smaller full-scales. Monitors with narrow bandwidth filter configurations are less susceptible to EMI than monitors configured with wide bandwidth. Shorter Alarm delay times may increase monitor susceptibility to transient EMI. Environments that exceed the product’s rated EMI levels may cause unpredictable monitor readings and/or system malfunction. 27 FieldMonitor Machinery Protection System Operation Manual 3.5 Mounting the Terminal Base Install the terminal base before inserting the modules. 3.5.1 Mounting the 1701/05 Terminal Base Mounting hole to secure AllenBradley interconnect cable with #6 Terminal base mounting holes (4 places), #8 machine screws 28 1.

Locate the slot offset switch on the terminal base under the area where the Power Supply will be inserted. NOTE: The slot offset address switch has been removed on more recent versions of terminal bases. Slot Offset Switch 32 Section 3 - Installation 2. If installed, verify the switch is set to the OFF position. If the switch is not OFF, then set it to the OFF position. 3.7 Connecting the Flex Modules Follow the steps below to ensure that the Flex modules, such as Flex I/O or Flex adapters, are properly connected to the 1701 terminal base. Use these rules: Refer to the appropriate product manuals to clarify any details about installing Flex modules and operating the Flex system, the network, or the host controller. Flex I/O modules that are not 1701 modules must be installed between the Flex adapter and the 1701 terminal base. You can connect up to 8 Flex I/O modules with 1701 modules to an adapter. For example if you plan to connect a 1701 terminal base with four 1701 monitors installed to an adapter, you can install 4 other Flex I/O modules on the same adapter. Direct Connection between a Flex module and 1701 Terminal Base (see also Appendix I) 1. Remove the cover plug (if used) on the male connector of the Flex module that you plan to connect to the 1701 terminal base. 2. Check that the 16 pins in the male connector of the Flex module are straight and in line so that the pins will align correctly with the pins of the female connector. 3. Pull and hold the connector tab on the female Flexbus connector on the 1701 TB or ITB so that it fully retracts into the base. 33 FieldMonitor Machinery Protection System Operation Manual If you will mount the terminal base over a DIN rail, perform steps 4 through 7. Otherwise skip these steps. 4. Hook the rear side of the Flex module over the DIN rail while engaging the “hook” on the 1701 base into the Hook receptacle located on the module. 5. Pull back on the Flex modules DIN clip and rotate the Flex module down onto the DIN rail. Take care that the female Flexbus connector does not strike any of the pins in the mating male connector. 34 Section 3 - Installation Note: For more detailed description with pictures of proper installation, see Appendix I at the end of the manual. DIN clip 6. Secure the Flex module onto the DIN rail and snap the Flex modules DIN clip into place. (The Flex module should now be flush against the terminal base and securely mounted on the rail.) 7. Verify that the Flex module is properly aligned with the female Flex connector on the terminal base. Gently push the female Flexbus connector into the adjacent adapter’s male connector and use the connector tab to complete the Flexbus connections. 35 FieldMonitor Machinery Protection System Operation Manual 8. Once the connector is in, firmly push it while holding the Adapter at the other end to ensure that the connector is fully inserted. Interconnect Cable Connection between a Flex Module and 1701 Terminal Base 1. Remove the cover plug (if used) from the male connector of the Flex module that will connect to the 1701 terminal base. 2. Check that the 16 pins in the male connector of the Flex module are straight and in line so that the pins will properly align with the pins of the female connector on the interconnect cable. 3. Gently push the female Flexbus connector on the interconnect cable labeled OUTPUT into the Flex module male connector. 4. Gently push the female Flexbus connector on the other end of the interconnect cable labeled INPUT into the male Flexbus connector labeled FLEX on the 1701 terminal base. 36 Section 3 - Installation 5. Insert #6 screws into the mounting holes of the interconnect cable. Tighten the screws to secure the cable to the mounting surface. 3.8 Installing the Power Supply Application Alert: The adapter and 1701 Terminal Base must be mounted on the DIN rail and flush with the mounting surface. Before you install the power supply, set the slot offset switch, if installed, to the off position and attach the Flex modules. 1. Verify connector alignment and insert the power supply into the 1701 terminal base. The heatsink of the power supply should be flush against the connector tab. 2. Tighten the mounting screws. (Inserting the power supply locks the Flexbus connectors together. Ensure that the connector tab is pushed into the adapters connector.) 37 FieldMonitor Machinery Protection System Operation Manual Although different types of 1701 modules install in the terminal base, the installation method is similar for each type 3.9 Installing 1701 Modules Use these rules: 38 • If you are using a 1701/05 TB then install monitors and transducer I/Os or internal Proximitor modules in pairs. Monitor/transducer pairs occupy adjacent slots having the same slot number, such as slots 2 and T2. For a list of which I/Os and internal transducers work with which monitors refer to “Compatibility of Monitors, Isolators, Internal and External I/O Modules” in Chapter 1. • If you are using a 1701/06 ITB then install monitors, transducer I/Os or internal Proximitor modules, and isolators in a set. Sets install in slots having the same number, such as a monitor in slot 2, its I/O or internal Proximitor module in slot T2, and the isolator in slot I2. For a list of which I/Os and internal Proximitor modules work with the isolator refer to “Compatibility of Monitors, Isolators, Internal and External I/O Modules” in Chapter 1. • Install a transducer I/O module or internal Proximitor module in slot T1K to use as a Keyphasor sensor. • Slot 1K is reserved for the FMIM. Do not install a monitor in this slot. • Install monitors so that empty slots are contiguous and at the opposite end from the power supply. For example if three monitors are installed, they should be in slots 2, 3, and 4. • Monitors, transducer I/O modules, internal Proximitor modules, and isolators are dual-channel devices. • Use the following table to determine where to install the modules.

This connection is made from the connectors on the top of the internal transducer module labeled channel A and B. Channel A Transducer cable Channel B 43 FieldMonitor Machinery Protection System Operation Manual 3.10.3 Routing the Proximity Transducer System Extension Cable and Field Wiring Route the extension cable using the following guidelines. (Refer to document AN028). Verify that the sum of the extension cable and probe lead length equals the Proximitor Sensor or Module system length. For example, a 3300 XL NSv 7 metre Proximitor Sensor will work with a 3300 NSv 6 metre extension cable and a 3300 NSv 1 metre probe. The color code of all post3300 series components must also be consistent. For the 3300 XL series, components will be marked with a blue color code. For the 3300 NSv series, components will be marked with a gray color code. Use mounting clips or similar devices to secure the extension cable to supporting surfaces. Identify the probe and both ends of the extension cable by inserting labels under the clear Teflon® sleeves. Apply heat to shrink the tubing once the labels are in place. Join the coax connectors between the Proximitor Sensor or Module, extension cable and probe lead. Tighten connectors to finger tight. Use either a connector protector or self-fusing silicone tape to protect the connection between the probe lead and the extension cable. Do not use self-fusing silicone tape to insulate a connection made inside of a machine. If the probe is in a part of the machine that is under pressure or vacuum, seal the hole where the extension cable leaves the machine by using appropriate cable seals and terminal boxes. 44 Section 3 - Installation 3.10.4 Power and Earth Connections Connect the instrument earth ground post to instrument earth. Connect the FieldMonitor system to power using the screw terminal blocks located on the 1701 terminal base next to the power supply. The positive terminal connects to +24Vdc, and the negative terminal connects to common. Instrument earth ground post Caution Reverse wiring will blow the fuse inside the power supply.

However, you can use external safety barriers with the 1701/05 terminal base system instead. 3.11 External Safety Barrier Considerations If you plan to use external zener barriers, you must address the following issues: • The FieldMonitor system does not support zener barriers with Seismoprobe® sensors or 2-wire, 10 kΩ impedance velocity sensors. • If you use zener barriers with external Proximitor Sensors or Acceleration sensors, you must program your monitors with a transducer scale factor that compensates for the signal attenuation caused by the barrier resistance and the monitor input impedance. Example The input impedance for the 1701/15 and 1701/25 monitors is 10 kΩ. The signal path resistance of a MTL 796(-) zener barrier is 435 Ω end-to-end. The attenuation caused by the voltage divider is: 10,000 = 0.958 10,000 + 435 Therefore the transducer scale factor is reduced by 4.2% so the configured scale factor should be reduced by 4.2%. • When your FieldMonitor system uses zener barriers with the 1701/05 TB, connect the instrument earth post to intrinsically safe earth. 47 Section 4 - How Communication Takes Place 4. How Communication Takes Place In this chapter, you will learn about: • • 4.1 Communica tion Over the Flex I/O Backplane/Term inal Base communication over the Flex I/O backplane between the adapter and Flex I/O modules (such as 1701 monitors) structure of the I/O data table One adapter can interface with up to eight Flex I/O modules, forming a Flex I/O system of up to eight slots (0 to 7). The controller considers each 1701 monitor to be one I/O module. Thus, a 1701/05 Terminal Base with 3 monitors installed would appear to the adapter as 3 I/O modules. In this case, up to 5 other Flex I/O modules could use the same adapter as the FieldMonitor system. If a 1701/05 TB has the maximum of four 1701 monitors, the adapter can interface with four other Flex I/O modules, making a total of eight Flex I/O modules. Any additional I/O modules should be located between the adapter and the 1701 Terminal Base. The adapter communicates to other network system components (controllers, scanners) over the network. The adapter communicates with its I/O modules over the backplane. 49 FieldMonitor Machinery Protection System Operation Manual Each 1701 monitor has its own I/O data table, which is divided into read and write words. Read words consist of input and status words that the controller reads from the 1701 monitor. Write words consist of output words (there are none in the 1701), and configuration words written to the 1701 monitor by the controller. All of the 1701 modules with data tables (1701/15, 1701/25 and 1701/30 monitors) have 6 read words (1 module status word + 5 input words) and 10 write words. The I/O data table is the memory map of all the data that can be read from or written to a particular monitor of the FieldMonitor system. The table below gives an overview of the I/O data table structure. 4.2 I/O Structure Refer to Appendices A, B, C, or D, for the I/O Data Table mapping of specific monitor types. Chapter 7, Configuration Options and I/O Data Tables, describes the configuration options and the fields in the data tables. See manual 144504-01 for Dynamic Pressure monitor information. 1701 Monitor I/O Data Table Structure Word Word 0 Word 1 Word 2 Word 3 Word 4 Word 5 Word 6 Word 7 Word 8 Word 9 Word 10 Word 11 Word 12 Word 13 Word 14 Word 15 Communication Direction Data Type Module Status Inputs Read Status Write Configuration Each slot with a monitor installed has its own unique I/O data table, which has the structure shown above. However, communication between the I/O modules and the adapter takes place by grouping all the inputs and outputs for all the I/O modules attached to a single adapter. 50 Section 4 - How Communication Takes Place The first word of input data that the adapter receives is the Module Status Word. The next input data that the adaptor receives is the input data for each slot, in the order of the installed I/O modules. The Input data for Slot 0 is the first data after the Module Status Word, followed by Input data for Slot 1 (referenced by a different I/O data table), and so on up to slot 7. Output data (not applicable for 1701) and configuration data from the I/O modules is received by the adapter in the order of the installed I/O modules. For example, data from slot 0 is received first, then data from slot 1 (referenced by a different I/O data table), and so on up to slot 7. 51 Section 5 - Programming the Module when using a Remote I/O Adapter 5. Programming the Module when using a Remote I/O Adapter This chapter describes: • how to program a 1701 monitor using a remote I/O adapter • how a controlling device sends configuration to the monitor 5.1 Programming a Monitor with Ladder Logic Block transfer programming lets you set up the communication between the controller and the monitor so that the controller can write configuration to the monitor and read data and status from the monitor. A configuration Block Transfer Write (BTW) is initiated 1. whenever power is cycled on the entire remote chassis containing the FieldMonitor system, 2. during the first scan of the ladder logic, and 3. when the programmer wants to enable or disable features of the monitor by changing the configuration data and toggling the Block Transfer Write configure bit. The configuration BTW sets the bits that enable the programmable features of the monitor, such as alarming options, full-scale ranges, etc. A controller performs a Block Transfer Read (BTR) to retrieve information from the monitor. BTR programming moves status and data from the monitor to the controller’s data table. The program in the controller initiates the request to transfer data from the monitor to the processor. The transferred words contain monitor vibration data and status information. 53 FieldMonitor Machinery Protection System Operation Manual Example ladder logic program to write configuration to and read data and status from a 1701 Monitor Note that the ladder logic above is for one monitor module only. Similar ladder logic must be written for each monitor being used in your FieldMonitor systems. Also note that the above ladder logic is for illustrative purposes only and should not be copied exactly, as every application is slightly different. 5.2 How Configuration is Sent to the Monitor 54 The monitor is configured using a group of data table words that are transferred to the monitor using a block transfer write instruction. See Chapter 7, Monitor Configuration and I/O Data Tables and Appendices A, B, C and D and Dynamic Pressure Monitor manual 144504-01 for more information. Section 6 - Programming the Module when using a ControlNet Adapter 6. Programming the Module when using a ControlNet Adapter In this chapter, for the ControlNet Adapter, we describe: • how to program the monitor using RSLogix5 or RSLogix5000 and RSNetworx for ControlNet Software • how configuration is sent to the monitor 6.1 Programming the Monitor using RSNetworx and RSLogix5 or RSLogix5000 Software RSNetworx Software lets you set up the network communication between the control device and the monitor so that the control device can write configuration to the monitor and read data and status from the monitor. The RSNetworx Map Editing Tool allows you to designate the data table addresses used to store the configuration data and receive the vibration data and status information. RSLogix software lets you enter configuration data values into the data table addresses associated with the monitors, view vibration data and status information from the monitors and manipulate data based on ladder logic conditions. The ControlNet protocol handles configuration writes and data / status reads in the scheduled network bandwidth. For more information on the ControlNet system and how it handles communication, refer to the user manuals for the RSNetworx and RSLogix software. 55 FieldMonitor Machinery Protection System Operation Manual 6.2 How Configuration is Sent to the Monitor 56 The controller configures a 1701 monitor using a group of data table words that can be transferred to the monitor using RSNetworx software for ControlNet software and protocol. The controller sends the configuration to the monitors whenever power is cycled on the entire remote chassis containing the FieldMonitor system. The controlling device can also send configuration using other methods. See the RSNetworx and/or ControlNet protocol documentation for more information. See also Chapter 7, Monitor Configuration and I/O Data Tables and Appendices A, B, C and D and Dynamic Pressure Monitor manual 144504-01 for more information. Section 7 - Configuration Options and I/O Data Tables 7. Configuration Options and I/O Data Tables The I/O data table is the memory map of data that a controller can read from or write to the modules in a FieldMonitor system. This chapter describes this data and Appendices A, B, C, and D list the location and settings of the individual bits in each word. This chapter lists the data descriptions by monitor type.

The write portion of the table (words 6 to 15) contains configuration and operating information used by 1701 modules. 57 FieldMonitor Machinery Protection System Operation Manual 7.2 Configuring and Programming a FieldMonitor System 1701 monitors do not detect the kinds of transducer I/O modules installed in the system or the types of transducers connected to the I/O modules. The FieldMonitor system cannot operate until the user has downloaded this information and the operating parameters for the monitors to the system. The process of collecting and then downloading this data to the FieldMonitor system is called configuring the FieldMonitor. The process of changing operating parameters during operation is called programming the monitors. To configure or program a FieldMonitor system, use this chapter to determine the configuration settings for the monitors in your system, and then configure or program your system by using configuration software or block transfers. If your controller has FieldMonitor Configuration Software for use with RSLogix software installed, use this software to configure or program your FieldMonitor system (see chapter 6). If your controller does not have programming software installed, use appendices A, B, C, or D to identify the bit settings in the write words (word 6 through 15) in the data table and then load the correct bits for your desired configuration by using block transfers (see chapter 5). 58 Section 7 - Configuration Options and I/O Data Tables 7.3 Radial Vibration Type 1701/15 Proximitor Input Monitor Program the 1701/15 Proximitor Input Monitor as a Radial Vibration Monitor using the Monitor Type configuration field (Word 15) in the data table. This section describes the configuration options for Radial Vibration. See Appendix A for the data table structure and bit field codes. The two channels in a radial vibration monitor provide the following data: Static Data Direct (overall) proportional values Gap voltage Status Data Monitor status Timed OK Channel Defeat setting Channel ON/OFF Alert alarm status Danger alarm status Trip Multiply status Channel inhibit status Channels in a radial vibration monitor use the following configuration parameters: Transducer Configuration Transducer Type Transducer Scale Factor Full-scale Range Alarm Settings Alert alarm time delay Danger alarm time delay Under and over alert gap setpoint Direct Alert setpoint Direct Danger setpoint Operating parameters Monitor reset Barrier type Set configuration Monitor type Channel ON/OFF Trip Multiply Level Setting Trip Multiply enable and disable Channel inhibit High-pass and low pass corner frequencies 7.3.1 Option Incompatibilities Application Advisory: Not all combinations of parameters are compatible with one another.

The Direct proportional value for channel A or B is an unsigned number placed in a 16-bit word where 1000 counts (0x03E8) is 100% of full scale, 2000 counts (0x07D0) is 200% of full scale, and 3000 counts (0x0BB8) is 300% of full scale. Engineering Units Direct value Counts Full Scale 1000 counts Bottom Scale 0 counts Percentage of full scale = (0.1)(Counts) Engineering units = ((Percentage of full scale)/100) x (Fullscale Range maximum value) Example 1: Calculate the percentage of full scale and the engineering units for a Direct proportional value output of 1000 counts (0x03E8) configured for a Full-scale Range of 0 - 5 mils. % of full scale = (0.1)(1000) = 100 % of full scale Engineering units = (100/100)x(5 mils) = 5 mils Example 2: Calculate the percentage of full scale and the engineering units for a Direct proportional value output of 500 counts (0x01F4) configured for a Full-scale Range of 0 to 150 µm % of full scale = (0.1)(500) = 50% of full scale Engineering units = (50/100)x(150 µm) = 75 µm Example 3: Calculate the percentage of full scale and the engineering units for a Direct proportional value output of 2500 (0x09C4), configured for a Full- scale Range of 0 to 10 mils. % of full scale = (0.1)(2500) = 250% of full scale Engineering units = (250/100)x(10 mils) = 25 mils 60 Section 7 - Configuration Options and I/O Data Tables 7.3.3 Gap Proportional Values Location Application Functional Description Words 2 and 4 Gap is the proportionally scaled dc voltage value. It is the negative dc output signal of a proximity probe that is proportional to the distance between the face of the probe tip and the observed surface. The gap voltage value for channel A or B is a signed integer placed in a 16-bit word, between 0 and -24,000 (0xA240) proportionally scaled to the 0 to -24 volts gap range. Engineering Units -24 Volts 0 Volts Gap value Counts -24,000 counts 0 counts To convert counts to Volts: Gap Voltage = Counts/1000 Example 1: Gap voltage for a reading of -9000 counts (0XDCD8). Gap Voltage = (-9000)/1000 = -9 Volts 7.3.4 Monitor Status Location Application Functional Description Word 5, bits 15 to 12 Determine status conditions for the monitor and individual channels. During normal operation, the controller must check these bits during every read. If the status bits are all true (1), then the monitor is configured, the channels are OK, and the monitor is processing alarms. In this case no further check is needed. If any bit is false (0), then decode and take appropriate action. The following diagnostic conditions are returned by the monitor: Monitor Statuses Unconfigured, (NO ALARMING) Ch A is OK and Ch B is Not OK Ch A is Not OK and Ch B is OK Ch A and Ch B are Not OK Config fault on Ch A and Ch B is OK Config Fault on Ch A and Ch B is Not OK Ch A is OK and Config fault on Ch B Ch A is Not OK and Config fault on Ch B Config fault on Ch A and Config fault on Ch B Hardware fault (NO ALARMING) Module OK, Config OK, Ch A and B OK 61 FieldMonitor Machinery Protection System Operation Manual 7.3.5 Timed OK Channel Defeat Location Application Functional Description Read Status = Word 5, bits 11 and 10 Holds a channel in the Not OK state for a fixed time after the channel transitions from Not OK to OK. This function can provide protection against false alarms caused by intermittent field wiring. For 1701/15 Radial Vibration monitors, Timed OK Channel Defeat is always enabled. When a channel returns to the OK state from a Not OK state, the monitor will continue to hold the channel in the Not OK state until the channel has been OK continuously for 30 seconds. During the time delay the channel will continue to return proportional values but it will not process alarms. The monitor will not alarm from an initial Not OK state. If a monitor goes Not OK, Timed OK Channel Defeat causes a Channel Inhibit. If the Read Status bit for Timed OK Channel Defeat is true or enabled, the Timed OK Channel Defeat function has been enabled in the configuration. 7.3.6 Channel On and Off Location Application Functional Description Alarms Read status = Word 5, bits 9 and 8 Enable or Disable = Word 15, bits 9 and 8 Take a channel out of service. If a channel is off, no alarms are returned. Proportional Values If a channel is off, an invalid proportional value of –32,768 is returned (0x8000). Monitor Status If a channel is off; Channel OFF is returned in the monitor read status word Channel OK is returned in the read status word Relation to other functions The off channel will not respond to other channel-based controls or configuration parameters. LED A monitor with both channels off will have a steady green LED. 7.3.7 Channel Alarm Status Location Application Functional Description Word 5 Bit number 7 6 5 4 Channel A A B B Alarm type Alert Danger Alert Danger An alarm setpoint is the level of vibration that causes the alarm status for the channel to go active. The Channel Alarm Status bit is true when the alarm level is exceeded for the Alarm Time Delay. Radial vibration monitors have two levels of alarm – Alert (sometimes called Alarm) and Danger (sometimes called Shutdown). Danger is the more serious alarm level. During monitor operation if the Direct proportional value is greater than the setpoint for the period of time selected by the Alarm Time Delay, then the monitor will set the appropriate alarm status bit true in the monitor’s Read Status Word 5. Gap Alarms drive the Alert bits. 62 Appendix A shows how to calculate the 8-bit integer for the alarm setpoint fields in the Channel Setpoints description. Section 7 - Configuration Options and I/O Data Tables 7.3.8 Channel Inhibit Location Read status = Word 5, bits 1 and 0 Enable or Disable = Word 15, bits 1 and 0 Prevent alarms and clear existing alarms on a channel basis while allowing continued reporting of proportional values. Application Functional Description Alarms With Channel Inhibit active, alarms for a channel will not annunciate. Channel Inhibit clears alarms that existed before inhibit occurred. If an alarm is active when Channel Inhibit goes inactive, that alarm will annunciate after the programmed time delay. Proportional Values The monitor will report proportional values with Channel Inhibit active. Monitor Status A channel with Channel Inhibit active will return active in the monitor read status word. Relation to other functions For a channel with Channel Inhibit active; a Not OK channel will continue to report proportional values but alarms are inhibited by Timed OK Channel Defeat, trip multiply can be enabled, a channel can be turned on or off. LED Remains green and steady if no other conditions exist, blinking red if Not OK. The Inhibit bit changes to 1 when voltage goes into the Not OK range. Timed OK Channel Defeat sets the Inhibit bit for a channel. • The Upper OK and Lower OK Limit values are fixed in firmware and can not be changed. They are downloaded from configuration for the various transducer types. • Gap Over and Under Setpoints are variable and can be changed through the configuration software. Setting the gap setpoints outside the OK limits will effectively disable the gap alarms. • The Typical Gap Value corresponds to the probe gap setting. Initially, the probe should be gapped such that the gap voltage value plus/minus the expected vibration is centered between the OK limit values. • 63 FieldMonitor Machinery Protection System Operation Manual 7.3.9 Trip Multiply Location Function read status enable or disable set TM level Application Functional Description Alarms 64 Word and bit number Channel A Channel B Word 5, bit 3 Word 5, bit 2 Word 15, bit 3 Word 15, bit 2 Word 15, bit 7 & 6 Word 15, bit 5 & 4 Multiplies the alarm setpoint levels on the selected channel by the Trip Multiply level.

Proportional Values The monitor will continue to report the channel proportional values in percent of full scale with a dynamic range of 300% of the full-scale range and resolution of 0.1% of full-scale range. Monitor Status A channel with Trip Multiply active will return active in the monitor status word. Relation to other functions Channel Inhibit and Channel On and Off can be applied while Trip Multiply is enabled. LED No effect. Section 7 - Configuration Options and I/O Data Tables 7.3.10 Transducer Type Location Application Functional Description 7.3.11 Words 6 and 7, bits 15 to 12 It is important to select the transducer type that matches the transducers connected to each channel. If you use external zener barriers, determine the effect on the scale factor and configure the correct scale factor. Transducers that are supported by the 1701/15 Radial Vibration Monitor: Internal 3300 series 8mm or 5mm Internal 7200 series 8mm or 5mm External 3300 series or 3300 XL series 8mm or 5 mm, includes PROXPAC 330800 External 3300 XL 11 mm External 7200 5/8mm External 7200 series 11 mm External 7200 series 14 mm External -18 Volt 3000 series External 3300 RAM or External 3300 XL NSv transducer Internal 3300 NSv transducer Some modified transducers, see appendix A for details Transducer Scale Factor Location Application Functional Description Words 6 and 7, bits 11 to 0 The transducer scale factor is used by the monitor to calculate the Direct proportional value. Loading a 12-bit, unsigned, binary integer in the channels scale factor field in the data table sets the scale factor. The adjustment range for transducer scale factor is ±15% around the nominal scale factor. The actual value loaded in the data table is a positive offset from the minimum scale factor. 65 FieldMonitor Machinery Protection System Operation Manual 7.3.12 Full-scale Range Location Application Functional Description Words 8 and 9, bits 15 to 12 Full-scale range is the engineering unit range for the Direct proportional value. Select a full-scale range to fit the expected Direct values. The Radial Vibration Type 1701/15 Proximitor Input Monitor supports the following full-scale ranges: English Metric 0 - 3 mils 0 - 5 mils 0 - 10 mils 0 - 15 mils 0 - 20 mils 0 - 100 um 0 - 125 um 0 - 150 um 0 - 200 um 0 - 250 um 0 - 300 um 0 - 400 um 0 - 500 um See Proportional Values description for scaling example. 7.3.13 Gap Alarm Setpoint (Over and Under Alert) Location Application Functional Description Words 8 and 9, bits 7 to 0, Word 10 Gap Alarm Setpoints are Alert level setpoints that can be set to flag when the gap value goes over or under a certain level. An Over or Under gap alarm will occur if the gap value goes more negative than the Over setpoint or more positive than the Under setpoint. Gap Alarm Setpoints can be set anywhere within the gap range of 0 to 240 counts proportional to 0 to -24 Volts. To convert the desired Gap Alarm Setpoint in Volts to Counts use this equation: Gap Alarm Counts = |(Gap Alarm Volts)(10counts/Volt)| Example 1: Set the gap alert over setpoint to -15 Volts: Gap alarm counts = |(-15 Volts)(10 counts/Volt)| = 150 (or 0x0096) Example 2: Set the gap Alert under setpoint to -4 Volts: Gap alarm counts = |(-4 Volts)(10 counts/Volt)| = 40 (or 0x0028) See Appendix A for other examples. Gap Alarms drive the Alert bit of Channel Alarm Status Word. 66 Section 7 - Configuration Options and I/O Data Tables 7.3.14 Direct Alarm Setpoints (Over Alert and Danger) Location Application Functional Description Word 11, and 12 Direct Alarm Setpoints are Alert or Danger level setpoints that can be set to flag if the Direct value goes over the Alert (first-level) Alarm level or Danger (second-level) Alarm level. To set alarm setpoints (Alert or Danger), load the setpoint field with an unsigned binary, 8-bit, integer scaled between 0 and 200 decimal. A setpoint of 200 corresponds to 100% of full scale and 0 corresponds to bottom scale. The setpoint resolution will be 0.5% of the full-scale range.

During normal operation, the controller must check these bits during every read. If the status bits are all true (1), then the monitor is configured, the channels are OK, and the monitor is processing alarms. In this case no further check is needed. If any bit is false (0), then decode and take appropriate action. The following diagnostic conditions are returned by the monitor: Monitor Statuses Unconfigured, (NO ALARMING) Ch A is OK and Ch B is Not OK Ch A is Not OK and Ch B is OK Ch A and Ch B are Not OK Config fault on Ch A and Ch B is OK Config Fault on Ch A and Ch B is Not OK Ch A is OK and Config fault on Ch B Ch A is Not OK and Config fault on Ch B Config fault on Ch A and Config fault on Ch B Hardware fault (NO ALARMING) Module OK, Config OK, Ch A and B OK, 79 FieldMonitor Machinery Protection System Operation Manual 7.5.4 Timed OK Channel Defeat Location Application Functional Description Read status = Word 5, bits 11 and 10 Enable or Disable = Words 8 and 9, bit 9 When Enabled, holds a channel in the Not OK state for a fixed time after the channel transitions from Not OK to OK and will inhibit alarming during a Not OK state. This function can provide protection against false alarms caused by intermittent field wiring. When Disabled the channel can alarm during a Not OK state and will transition from Not OK to OK with no time delay. This can provide protection against missed alarms due to sudden impact events that can cause the sensor output to exceed the OK limits. When Enabled and a channel returns to the OK state from a Not OK state, the monitor will continue to hold the channel in the Not OK state until the channel has been OK continuously for 30 seconds. During this time the channel will continue to return proportional values but it will not process alarms. When Enabled alarming is inhibited during the Not OK state. When Disabled, the monitor will process alarms even if the channel is Not OK and will return to the OK state at the same time the cause of the Not OK condition is removed. If the Read Status bit for Timed OK Channel Defeat is true or enabled, the Timed OK Channel Defeat function has been enabled in the configuration. Application Alert: For machine protection systems using Velomitor sensors or acceleration sensors a sudden mechanical impact can produce and over-range condition. If the monitor configuration has Timed OK Channel Defeat enabled and the over-range signal exceeds the OK Limits, the monitor may not annunciate an alarm. This may result in a missed alarm and temporary loss of machine protection. For example, mechanical impacts can occur on reciprocating compressors. When measuring crankcase velocity or crosshead acceleration on reciprocating compressors, you must Disable the Timed OK Channel Defeat option. 7.5.5 Channel On and Off Location Application Functional Description Alarms Proportional Values Monitor Status Relation to other functions LED 80 Read status = Word 5, bit 9 and 8 Enable or Disable = Word 15, bit 9 and 8 Take a channel out of service.

The Direct proportional value for channel A or B is an unsigned number placed in a 16-bit word where 1000 counts (0x03E8) is 100% of full scale, 2000 counts (0x07D0) is 200% of full scale, and 3000 counts (0x0BB8) is 300% of full scale. Engineering Units Direct value Counts Full Scale 1000 counts Bottom Scale 0 counts Percentage of full scale = (0.1)(Counts) Engineering units = ((Percentage of full scale)/100) x (Full-scale Range maximum value) Example 1: Calculate the percentage of full scale and the engineering units for a Direct proportional value output of 1000 counts (0x03E8) configured for a fullscale range of 0 - 2 g pk. % of full scale = (0.1)(1000) = 100 % of full scale Engineering units = (100/100)x(2 g pk) = 2 g pk Example 2: Calculate the percentage of full scale and the engineering units for a Direct proportional value output of 500 counts (0x01F4), configured for a full-scale 2 range of 0 to 100 m/s rms % of full scale = (0.1)(500) = 50% of full scale 2 Engineering units = (50/100)x(100 m/s rms) 2 = 50 m/s rms Example 3: Calculate the percentage of full scale and the engineering units for a Direct proportional value output of 2500 (0x09C4), configured for a full-scale range of 0 to 50 mm/s pk, integrated acceleration. % of full scale = (0.1)(2500) = 250% of full scale Engineering units = (250/100)x(50 mm/s pk) 87 FieldMonitor Machinery Protection System Operation Manual =125 mm/s pk 7.6.3 Monitor Status Location Application Functional Description Word 5, bits 15 to 12 Determine status conditions for the monitor and individual channels. During normal operation, the controller must check these bits during every read. If the status bits are all true (1), then the monitor is configured, the channels are OK, and the monitor is processing alarms. In this case no further check is needed. If any bit is false (0), then decode and take appropriate action. The monitor returns the following diagnostic conditions: Monitor Statuses Unconfigured, (NO ALARMING) Ch A is OK and Ch B is Not OK Ch A is Not OK and Ch B is OK Ch A and Ch B are Not OK Config fault on Ch A and Ch B is OK Config Fault on Ch A and Ch B is Not OK Ch A is OK and Config fault on Ch B Ch A is Not OK and Config fault on Ch B Config fault on Ch A and Config fault on Ch B Hardware fault (NO ALARMING) Module OK, Config OK, Ch A and B OK, 7.6.4 Timed OK Channel Defeat Location Application Read status = Word 5, bits 11 and 10 Enable or Disable = Words 7 and 8, bit 9 When Enabled, holds a channel in the Not OK state for a fixed time after the channel transitions from Not OK to OK and inhibits alarming from a Not OK state. This function can provide protection against false alarms caused by intermittent field wiring. When Disabled, the channel can alarm from a Not OK state. This can provide protection against missed alarms due to sudden impact events that can cause the sensor output to exceed the OK limits. Functional Description When Enabled and a channel returns to the OK state from a Not OK state, the monitor will continue to hold the channel in the Not OK state until the channel has been OK continuously for 30 seconds. During this time the channel will continue to return proportional values but it will not process alarms. When Enabled, alarming is inhibited during a Not OK state. When Disabled, the monitor will process alarms even if a channel is Not OK and will return to the OK state at the same time the cause of the Not OK condition is removed. If the Read Status bit for Timed OK Channel Defeat is true or enabled, the Timed OK Channel Defeat function has been enabled in the configuration. 88 Section 7 - Configuration Options and I/O Data Tables Application Alert: For machine protection using Velomitor sensors or acceleration sensors, a sudden mechanical impact can produce an over-range condition. If the monitor configuration has Timed OK Channel Defeat enabled and the over-range signal exceeds the OK Limits, the monitor may not annunciate an alarm. This may result in a missed alarm and temporary loss of machine protection. For example, mechanical impacts can occur on reciprocating compressors. When measuring crankcase velocity or crosshead acceleration on reciprocating compressors, you must Disable the Timed OK Channel Defeat option. 7.6.5 Channel On and Off Location Application Functional Description Alarms Proportional Values Monitor Status Relation to other functions LED Read status = Word 5, bits 9 and 8 Enable or Disable = Word 15, bits 9 and 8 Take a channel out of service. If a channel is off, no alarms are returned. If a channel is off, an invalid proportional value of –32,768 (0x8000) is returned. If a channel is off, Channel OFF is returned in the monitor read status word Channel OK is returned in the read status word The off channel will not respond to other channel-based controls or configuration parameters. A monitor with both channels off will have a steady green LED. 7.6.6 Channel Alarm Status Location Application Functional Description Word 5 Bit number 7 6 5 4 Channel A A B B Alarm type Alert Danger Alert Danger An alarm setpoint is the level of vibration that causes the alarm status for the channel to go active. The Channel Alarm Status bit is true when the alarm level is exceeded for the Alarm Time Delay. This monitor has two levels of alarm – Alert (sometimes called Alarm) and Danger (sometimes called Shutdown). Danger is the more serious alarm level. During monitor operation if the Direct proportional value is greater than the setpoint for the period of time selected by the Alarm Time Delay then the monitor will set the appropriate alarm status bit true in the monitor’s Read Status Word 5. Appendix D shows how to calculate the 8-bit integer for the alarm setpoint fields. 89 FieldMonitor Machinery Protection System Operation Manual 7.6.7 Channel Inhibit Location Application Functional Description Alarms Read status = Word 5, bits 1 and 0 Enable or Disable = Word 15, bits 1 and 0 Prevent alarms and clear existing alarms on a channel basis while allowing continued reporting of proportional values. With Channel Inhibit active, alarms for a channel will not annunciate. Channel Inhibit clears alarms that existed before inhibit occurred. If an alarm is active when Channel Inhibit goes inactive, that alarm will annunciate after the programmed time delay. Proportional Values The monitor will report proportional values with Channel Inhibit active. Monitor Status A channel with Channel Inhibit active will return active in the monitor read status word. For a channel with Channel Inhibit active; a Not OK channel will continue to report proportional values and if Timed OK Channel Defeat is enabled, alarms are inhibited Trip multiply can be enabled a channel can be turned on or off Remains green and steady if no other conditions exist.

The monitor will continue to report the channel proportional values in percent of full scale with a dynamic range of 300% of the full-scale range and resolution of 0.1% of full-scale range. A channel with Trip Multiply active will return active in the monitor status word. Channel Inhibit and Channel On and Off can be applied while Trip Multiply is enabled. No effect. Section 7 - Configuration Options and I/O Data Tables 7.6.9 Transducer Type Location Application Functional Description 7.6.10 Transducer Scale Factor Location Application Functional Description 7.6.11 Words 6 and 7, bits 11 to 0 The monitor uses the transducer scale factor to calculate the Direct proportional value. Loading a 12-bit, unsigned, binary integer in the channel’s scale factor field in the data table sets the scale factor. The adjustment range for the transducer scale factor is ±15% around the nominal scale factor. The actual value loaded in the data table is a positive offset from the minimum scale factor. Timed OK Channel Defeat On/Off Location Application/ Functional Description 7.6.12 Words 6 and 7, bits 15 to 12 It is important to select the transducer type that matches the transducers connected to each channel. The Acceleration Type 1701/25 Seismic Input Monitor supports the following transducers: 330400, 100 mV/g, 20 kHz or less -3dB BW 330450 w/mod 159937-01, 100 mV/g, 20 kHz or less -3dB BW 23733-03 I/F module, 100 mV/g, 20 kHz or less -3dB BW 24145-02, 100 mV/g, High frequency 330425, 25 mV/g, 20 kHz or less -3dB 49578-01, 25 mV/g, 20 kHz or less -3dB 24145-02 w/mod 1555023-01, 25 mV/g, High frequency Word 8 and 9, bit 9 (8-0 are unused) Described above in the read status word 5 descriptions. Full-scale Range Location Application Functional Description Words 8 and 9, bits 15 to 10 Full-scale range is the engineering unit range for the Direct proportional value. Select a full-scale range to fit the expected Direct values. The Acceleration Input 1701/25 Seismic Input Monitor supports the following fullscale ranges: English Metric Acceleration, Integrated Acceleration, Integrated 2 gs pk or gs rms Acceleration, m/s pk or Acceleration, 2 in/s pk or in/s rms m/s rms mm/s pk or mm/s rms 0-2 0 - 1.0 0 - 20 0 - 25 0-5 0 - 2.0 0 - 50 0 - 50 0 - 10 0 - 100 0 - 100 0 - 20 0 - 200 0 - 25 0 - 250 0 - 40 0 - 400 0 - 50 0 - 500 See Proportional Values description for scaling example. 91 FieldMonitor Machinery Protection System Operation Manual 7.6.13 Direct Alarm Setpoints (Over Alert and Danger) Location Application Functional Description Words 11 and 12 Direct Alarm Setpoints are Alert or Danger level setpoints that can be set to flag if the Direct value goes over the Alert (first-level) Alarm level or Danger (second-level) Alarm level. To set alarm setpoints (Alert or Danger), load the setpoint field with an unsigned binary, 8-bit, integer scaled between 0 and 200 decimal. A setpoint of 200 corresponds to 100% of full scale (top scale) and 0 corresponds to bottom scale. The setpoint resolution will be 0.5% of the full-scale range. To convert the desired Direct Alarm Setpoint in engineering units to Counts use this equation: Direct Alarm Counts = (Direct Alarm Engineering Units)(200 counts/full-scale range) Example 1: I want a Direct Alert over setpoint at 1 g pk where the full-scale range is 0 to 2 g pk. How do I convert this 1 g pk to counts so I can configure the setpoint? Direct alarm counts = (1 g pk)(200 counts/2 g pk)) = 100 counts (0x0064 ) Example 2: 2 Convert a desired Direct Danger over setpoint of 75 m/s pk to counts for a full-scale 2 range of 0 to 100 m/s pk. 2 2 Direct alarm counts = (75 m/s pk)(200 counts/100 m/s pk) = 150 counts (0x0096) See Appendix D for additional examples. 7.6.14 High and Low Pass Corner Frequency Location Application Functional Description Word 13, bits 7 to 4 and bits 15 to 12 Set up desired filter corners for Direct proportional values. The combined high-pass and low-pass filters set up the desired band-pass filter for the Direct proportional values for your specific application. The minimum high-pass corner frequency is 3 Hz, 10 Hz, or 20 Hz, depending on the acceleration monitor type, transducer type, and full-scale range. The maximum low-pass corner frequency is 14.05 kHz, 31.55 kHz, or 24.3 kHz, depending on the acceleration monitor type. High- and low-pass corner frequencies are adjustable options, and allowable frequency ranges vary with specific monitor type, transducer type, and full-scale range. Refer to compatibility tables in Appendix D for specific filter corners that your monitor type, transducer type, and full-scale range allow. 92 Section 7 - Configuration Options and I/O Data Tables 7.6.15 Alarm Time Delay Location Application Functional Description 7.6.16 Monitor Reset Location Application Functional Description 7.6.17 Word 15, bit 15 Unused, always set low (0).

If this bit is set to 0, the monitor will not operate. 93 FieldMonitor Machinery Protection System Operation Manual 7.6.19 Monitor Type Location Application Word 15, bits 11 and 10 Identify the monitor type being used. Use the following table to select which Acceleration Type is appropriate for your application Acceleration Application Monitor Type Use this type if you want to program one or both Dual channels for peak or rms acceleration monitoring and Acceleration, you want to set programmable low-pass filters. The 14.05 kHz; maximum signal frequency for these channels is 14.05 Bit 11 low (0) kHz. You should also use this type if you want to Bit 10 high (1) program one or both channels for monitoring peak or rms velocity (integrated acceleration). The maximum signal frequency for these channels is also 14.05 kHz and you can set any of the programmed low-pass filters that are within the bandwidth. Dual Acceleration, 31.55 kHz; Bit 11 high (1) Bit 10 low (0) High-pass filters are programmable in all cases. Use this type if you want to program both channels for wide band peak or rms acceleration monitoring to 31.55 kHz. You should also use this type if you want to program one channel (Channel B must be used) for wide band peak or rms acceleration monitoring with a fixed 31.55 kHz low-pass filter and the other channel (Channel A) for peak or rms acceleration monitoring with programmable low pass filters up to 31.55 kHz. High-pass filters are programmable in all cases. Single Acceleration, 24.3 kHz; Bit 11 high (1) Bit 10 high (1) Use this type when you have only a single transducer connected to the monitor and you want to monitor peak or rms acceleration to 24.3 kHz with programmable low-pass filters or you want to monitor peak or rms velocity to 24.3 kHz with the capability to set low-pass filters. High-pass filters are programmable in all cases Channel A will be the active channel and Channel B will be OFF. Functional Description 7.6.20 Channel On/Off, Trip Multiply, and Channel Inhibit Location Application/ Functional Description 94 If you require only one active channel on a 1701/25 Acceleration type then you should choose this type. The single channel type will provide wider bandwidths with programmable filter capability than the dual channel types. If the Monitor Type bit (word 15, bits 11 and 10) settings are not correct, the monitor will not function correctly. Be sure to configure the monitor for the correct monitor type.

You will simulate transducer signals with the test equipment or apply signals directly using a micrometer kit. 96 Section 8 - System Verification 8.1.2 Monitor LED status The table below shows how to interpret the monitors LED. STATUS LED state OFF Green flashing at 1 Hz Green steady Alternate green/red flashing Red flashing at 1 Hz Alternate 5 Green and 1 Red flashing at 1 Hz Red steady Condition Power is off or some component is defective. See the troubleshooting section. Monitor is not configured. Monitor is configured and monitor and transducers are in an OK condition. One or both channels are in alarm. A recoverable fault condition exists such as: one or both transducer channels are Not OK, Timed OK Channel Defeat is active, the monitor is Not OK, or the configuration is invalid. A communication problem exists between the Monitor and the Flex Adapter. Verify that the Terminal Base Flex connector is properly attached to the Adapter, that there are no bent pins in the Adapter and that power is properly applied. See Appendix I. Non-recoverable fault. See troubleshooting section, page 141. 8.1.3 Monitor Signal Scaling Application Advisory Radial vibration channels or seismic channels with Timed OK Defeat enabled will remain in a Not OK state for 30 seconds after the transducer signal returns to an OK condition. During verification testing you must wait 30 seconds after applying an OK condition before verifying the channel OK status. The monitor returns Direct proportional values for 1701/15 radial vibration channels and 1701/25 velocity and acceleration channels as counts. The monitor scales Direct counts so that 0 counts is bottom scale and 1000 counts equals the full scale, and alarm counts so that 0 counts is bottom scale and 200 counts equals the full scale. For the radial vibration channels, the monitor scales gap counts so that 0 counts is bottom scale and –24,000 counts equals the full scale, and 240 counts equals the full scale alarm value. The figure below shows the relation between the full-scale range in engineering units, Direct value counts, and the Direct alarm setpoint scale in counts. Engineering Units Direct value Counts Direct Value Alarm Counts Full Scale 1000 counts 200 counts Bottom Scale 0 counts 0 counts 97 FieldMonitor Machinery Protection System Operation Manual Gap scaling for the 1701/15 radial vibration channels is shown below. Engineering Units Gap value Counts Gap Value Alarm Counts -24 volts -24,000 counts 240 counts 0 volts 0 counts 0 counts The monitor scales Direct proportional values for 1701/15 thrust channels so that 0 counts corresponds to the zero scale position and 1000 counts equals the full scale, with +500 counts being equal to full upscale and -500 counts being equal to full downscale. It scales alarm counts so that 0 counts is full downscale and 200 counts equals full upscale, as shown below. Gap values for thrust channels are the same as for radial vibration channels discussed above except that thrust does not have gap value alarms. 98 Section 8 - System Verification Engineering Units Direct value Counts Full Up Scale 500 counts Zero Position Full Bottom Scale Direct Value Alarm Counts 200 counts 0 counts -500 counts 0 counts Your display HMI software maps the Direct and Gap value counts to engineering units.

Contact could cause shock, burns, or death. I/O module and terminals Application Advisory Use the transducer scale factor that is loaded in the I/O data table for the monitor and channel. Function generator setting Waveform: Sinewave DC Offset: 0 Vdc Frequency: 100 Hz Amplitude: Minimum level 1. Disconnect Vt (transducer power), COM, and SIG field wiring from the channel terminals on the terminal base. 2. Connect the test equipment as shown. Use the same connection for the 1701/05 and 1701/06 terminal bases. 3. Use the equation and examples below to calculate the full-scale voltage. Adjust the function generator amplitude to the calculated voltage. Full-scale Voltage = Direct Full-scale Range x Transducer Scale Factor Example 1 Direct Full-scale Range = Transducer Scale Factor = Full-scale Voltage = = 5 mil pp 200 mV/mil pp (5 mil pp) x ( 200 mV/mil pp) 1.000 Vpp For an input in Vrms (assuming a pure sinusoid from the generator) Vrms Full-scale Voltage = = Example 2 Direct Full-scale Range = Transducer Scale Factor = Full-scale Voltage = = (0.707) x (Vpp Full Scale Voltage/2) 0.3535 Vrms 150 µm pp 7.874 mV/µm pp (150 µm pp) x (0.007874 V/µm pp) 1.181 Vpp For an input in Vrms (assuming a pure sinusoid from the generator) Vrms Full-scale Voltage = = (0.707) x (Vpp Full-scale Voltage/2) 0.4175 Vrms 4. Verify that the Direct reading is within specification. Terminal Base Type Tolerance in percent of full-scale range 1701/05 TB ± 1% 1701/06 Isolator TB Full-scale Ranges less than 200 mV peak to peak Full-scale Ranges more than 200 mV peak to peak +4% to +2% +1% to –2% If the reading does not meet specification check your 100 Section 8 - System Verification input signal and connections for problems. If none are found and the monitor still does not meet specification go to the section “If a Channel Fails a Verification Test” on page 137. Steps 5 through 9 verify Direct alarms Application Advisory If your controller is programmed for latching alarms you will need to reset them to verify that the alarms are now inactive. 5. Adjust the function generator amplitude below the Alert alarm level. 6. Verify that the channel is not in alarm by observing the alarm status on the HMI or by verifying that the monitor LED is a steady green. (Note that both channels must be OK for the LED to be a steady green.) 7. Adjust the function generator so that the signal just exceeds the Alert/A1 setpoint level. After the appropriate alarm time delay has expired, verify that the HMI indicates Alert or verify that the LED indicates correctly. (Both channels must be OK for the LED to indicate alarms.) 8. Adjust the function generator so that the signal just exceeds the Danger/A2 setpoint level. After the appropriate alarm time delay has expired, verify that the HMI indicates Danger. 9. Adjust the function generator so the signal is below the Alert setpoint level. Verify that the HMI indicates no active alarms and that the LED indication is correct. Steps 10 and 11 verify the Gap value. 10. Adjust the function generator amplitude to minimum value and then set the DC power supply to -18.000 Vdc. 11. Verify that the Gap value reading is -18.000 volts ± 20 mV (± 120 mV for internal isolator systems). (Note this may cause a Not OK condition.) Step 12 verifies Gap alarms. 12. To verify the Gap alarms adjust the DC power supply to a value that is between the Over/Under Gap alarm setpoints. Verify that the Alert alarm status is not active. Adjust the DC power supply to a voltage more positive than the Under Gap setpoint but more negative than the lower OK limit. After the alarm time delay expires, verify 101 FieldMonitor Machinery Protection System Operation Manual that Alert/A1 is active. Adjust the power supply back to a value between the Over/Under Gap setpoints (press reset if the alarms are latching alarms) and verify that the alarms are not active. Adjust the power supply to a voltage more negative than the Over Gap setpoint but more positive than the upper OK limit. Verify that Alert/A1 is active. See page 63 for more details. Step 13 verifies the OK limits. Appendix A shows the OK Limit tables. 13. To test the OK limits, set the function generator to its minimum output and adjust the DC power supply to 9.00 Volt. Verify that the channel status is OK. Gradually increase (more negative) the power supply voltage over the upper OK limit. Verify that the HMI reports Not OK and that the monitor LED is flashing red. (Note: The other channel must be OK or you cannot use the LED as an indicator.) Adjust the power supply voltage back to 9.00 V and verify that the channel status is OK. Decrease the power supply voltage (more positive) below the lower OK limit and verify that the channel status is Not OK. 14. Disconnect the test equipment and reconnect Vt, COM, and SIG field wiring to the terminals. Verify that the channel status returns to the OK state. 15. Repeat steps 1 through 14 for the other channel. 102 Section 8 - System Verification 8.1.5 Verifying 1701/15 Radial Vibration Channels using internal Proximitor Sensors Danger High voltage present. Contact could cause shock, burns, or death. Do not touch exposed wires or terminals. Application Advisory TK-3 wobble plates are rated for specific maximum peak to peak displacement. You will need a wobble plate that meets your full-scale range requirement or you cannot create a full-scale signal. Note that standard wobble plates are AISI 4140 steel. If your Proximity transducer system has been modified for other target materials then you should not use this procedure. This verification method requires special equipment and is not suitable for verifying monitor accuracy specifications. It is also difficult and time-consuming. An alternate procedure is to replace the internal Proximitor module with a 17018001 Proximitor/ Accelerometer I/O Module and use the procedure described in, “Verifying 1701/15 Proximitor Input Monitor radial vibration channels configured for external Proximitor sensors” described in the previous section to verify that the monitor-to-controller link is functioning correctly. Then re-install the internal Proximitor module and verify its functionality using the procedure described under “Internal Proximitor Verification” on page 137. The section below describes the verification procedure using a TK-3. 1. Use the dial indicator supplied with the TK-3 to adjust the position of the probe holder to the full-scale peak-topeak displacement. 2. Connect the test equipment by installing the probe in the TK-3 wobble plate and connecting the oscilloscope to the channels buffered output as shown. 3.

Verify that the Direct reading is correct. If the reading does not meet specification, check your input, connections, and wobble plate for problems. If you find no problems and the monitor still does not meet specification, go to the section “If a Channel Fails a Verification Test” on page 137. 6. Adjust the probe holder to reduce the peak-to-peak displacement below the Alert setpoint level. Steps 7 through 11 verify Direct alarms 7. Verify that the channel is not in alarm by observing the alarm status on the HMI or by verifying that the monitor LED is a steady green. (Note that both channels must be OK for the LED to be a steady green.) 8. Adjust the probe holder so that the signal just exceeds the Alert/A1 setpoint level. After the appropriate alarm time delay has expired, verify that the HMI indicates Alert or verify that the LED indicates correctly. (Both channels must be OK for the LED to indicate alarms.) 9. Adjust the probe holder so that the signal just exceeds the Danger/A2 setpoint level. After the appropriate alarm time delay has expired, verify that the HMI indicates Danger. 10. Adjust the probe holder so the signal is below the Alert setpoint level. Verify that the HMI indicates no active alarms and that the LED indication is correct. Steps 11 through 15 verify the Gap value 104 Section 8 - System Verification Application Advisory If your controller is programmed for latching alarms, you will need to reset them to verify that the alarms are now inactive. 11. Turn off the TK-3 and install the probe in the spindle micrometer with the appropriate target. 12. Replace the oscilloscope with the multimeter. 13. Gap the probe at -9.00 V ± 1.00 V for the 170133 or 170172 internal Proximitor Sensors. Gap the probe at 7.00 V ± 1.00 V for the 170150 internal Proximitor Sensor. 14. Wait 30 seconds and then verify that the channel status is OK and that the monitor LED indication is correct. 15. Adjust the micrometer until the multimeter reads -18.000 V ± 50 mV for the 170133 or 170172 internal Proximitor Sensors. Adjust the micrometer until the multimeter reads -14.000 V ± 50 mV for the 170150 internal Proximitor Sensor. (Note: This will cause a Not OK condition.) 16. Verify that the monitor gap value matches the multimeter reading ± 20 mV, (± 120 mV for the 1701/06 Isolator Terminal Base). Step 17 verifies the Gap alarms. 17. To verify the gap alarms adjust the micrometer to a gap that is between the Over/Under Gap alarm setpoints. Verify that the Alert alarm status is not active. Adjust the micrometer to a gap less than the Under Gap setpoint but greater than the lower OK limit. After the alarm time delay expires, verify that the Alert/A1 is active. Adjust the micrometer to be between the Over/Under Gap setpoints (press reset if alarms are latching) and verify that the alarms are not active. Adjust the micrometer to a gap greater than the Over Gap setpoint but less than the upper OK limit. Verify that the Alert/A1 is active. See page 63 for more details. Step 18 verifies the OK limits. Appendix A shows the OK limit tables. 105 FieldMonitor Machinery Protection System Operation Manual 18. To test the OK limits adjust the micrometer to a gap that yields a Gap voltage of -9.00 V ± 1.0 V for the 170133 or 170172 internal Proximitor Sensors or -7.00 V ± 1.0 V for the 170150 internal Proximitor Sensor.

Adjust the power supply voltage back to approximately -9.00 V (for the 170133 or 170172) or -7.00 Volt (for the 170150) and verify that the channel status is OK. Decrease gap until the Gap voltage is below the lower OK limit and verify that the channel status is Not OK. 19. Disconnect the test equipment and remove the probe from the TK-3.

Step 18 verifies the Gap value 18. For the 170133 or 170172 internal Proximitor Sensors, use the micrometer to adjust the gap so that the multimeter reads -18.00 V. Verify that the gap value is 18.000 V ± 20 mV (-18.000 V ± 120 mV for the 1701/06 Isolator Terminal Base). For the 170150 internal Proximitor Sensor, use the micrometer to adjust the gap so that the multimeter reads -14.00 V. Verify that the gap value is -14.000 V ± 20 mV (-14.000 V ± 120 mV for the 1701/06 Isolator Terminal Base).

Testing verifies the corner frequencies by measuring the amplitude at the filter corners. Application Advisory If the channel units are integrated, change the configuration to a nonintegrated full-scale range to test the filters. After you are finished return the channel to its original configuration.

After you are finished return the channel to its original configuration. The procedure for testing these parameters simulates an Acceleration signal with a function generator and power supply. The testing verifies the corner frequencies by measuring the amplitude at the filter corners. Use the test equipment setup, verification frequency calculation, and full-scale voltage calculations shown in the previous section on “Verifying 1701/25 Seismic Input Monitor Acceleration Channels”. 135 FieldMonitor Machinery Protection System Operation Manual 1.

Adjust the function generator to the full-scale voltage. 5. Verify that the Direct value at the HMI reads correctly. 6. Adjust the function generator frequency to the low-pass filter corner frequency. Verify that the Direct value reads between 65% and 75% of full scale. If you are using the 1701/06 Isolator Terminal Base with internal isolators you may need to account for the amplitude frequency response of the internal isolator. Refer to the specification in Appendix E. 7. Adjust the function generator frequency to the high-pass filter corner frequency. Verify that the Direct value reads between 65% and 75% of full scale. If you are using the 1701/06 Isolator Terminal Base with internal isolators you may need to account for the amplitude frequency response of the internal isolator. Refer to the specification in Appendix E. 8. If the reading does not meet specification, check the input signal for problems. If you find no problems and the monitor still does not meet specification, go to the section on “If a Channel Fails a Verification Test” on page 137. 9. Disconnect the test equipment and reconnect A and B field wiring to the channel terminals on the terminal base. Verify that the channel returns to the OK state. 136 Section 8 - System Verification 10. Return the channel to its original configuration. 11. Repeat steps 1 through 10 for other configured channels. 8.1.13 If a Channel Fails a Verification Test Application Advisory When the internal galvanic isolators are used, they affect accuracy, offset, and frequency response. Before deciding that a channel has failed, check the isolator specification in Appendix E. 1. Replace the module with a spare. Refer to Chapter 3 for installation instructions and to Chapter 10 for ordering information. 2. Return the faulty module to Bently Nevada for repair. Be sure to describe the symptoms of the problem, the configuration of the monitor, and the test it failed. 3. Verify the operation of the spare. 8.2 Internal Proximitor Module Verification The transducer system does not require verification at regular intervals. You should, however, verify operation by using the scale factor verification procedure explained below if any of the following conditions occur: components of the system are replaced or disturbed, • the performance of the system changes or becomes erratic, or • you suspect that the transducer is not calibrated correctly The scale factor verification procedure requires the following instruments: 3-1/2 digit multimeter Spindle micrometer The scale factor verification procedure uses the test setup as shown in the following figure: • 137 FieldMonitor Machinery Protection System Operation Manual 138 Section 8 - System Verification 8.2.1 Scale Factor Verification 1 3 2 Multimeter 460 µm 500 µm or 18 mil or 20 mil -3.00 ± 0.1 Vdc 500 µm 200 µm or 20 mil 8 mil or 250 µm Set the micrometer to 18 mils and then back it out to 20 mils.

Also, replace 2000 µm with 1500 µm and 80 mils with 60 mils when calculating the ASF for the 170150 Proximitor module. If the incremental scale factor (ISF) or the average scale factor (ASF) of the system is out of tolerance, contact Bently Nevada for further information on possible calibration problems. 8.3 Transducer I/O Module Verification The transducer I/O modules are verified as part of the Monitor Verification procedure. If you suspect a problem with a transducer I/O module you should replace it with a spare. If this corrects the problem, replace the faulty I/O module. 8.4 Internal Galvanic Isolator Verification The internal isolators are verified as part of the Monitor Verification procedure. If you suspect a problem with an internal isolator you should replace it with a spare. If this corrects the problem, replace the faulty isolator. 8.5 24 Volt Power Supply Verification Apply power and verify that the power supply OK LED is on steady. If the OK LED is not on steady, go to Troubleshooting, section 9. 140 Section 9 - Troubleshooting 9. Troubleshooting This chapter describes how to troubleshoot problems with: 9.1 System Troubleshooting • the system, • monitors, • internal Proximitor modules, • transducer I/O modules, • internal isolators, and • power supply. This section describes some methods to troubleshoot communication problems. These types of communication problems are identified by a fault condition on the adapter LEDs or system software. 9.1.1 Communication Problems Application Advisory POWER SEQUENCING If certain types of adapters are powered before the FieldMonitor system then the adapter may not detect the 1701 modules. Sequence power so that the FieldMonitor system and the adapter power at the same time. The network adapters have a set of indicator LEDs on their top panel. Use the adapter’s manual to identify the LED fault indications. Typically, the network management software or the adapter LEDs will help you determine if the problem is on the network side or on the Flexbus side (local). For example an Allen-Bradley 1794 ACN will indicate a missing module by a red STATUS LED. If the problem is on the network use your network, adapter, and controller documentation to troubleshoot the problem. If the problem is “local” then use your adapter and Flex documentation plus the steps below to troubleshoot the problem. The most common fault is a mismatch between the installed modules and the configuration. 1. Verify that the configuration loaded in the controller is valid and matches the type, position, and number of the 1701 monitors and Flex modules. 141 FieldMonitor Machinery Protection System Operation Manual 2. Verify that your adapter has the correct address. 3. Verify that the positions of the installed modules match their configuration. (If a monitor is removed under power it will generate a fault.). If you change configuration, cycle power to the adapter and the FieldMonitor system. 4. Verify that the 1701 Slot Offset switch (if installed) is correctly set in the “OFF” position. See “Setting the Slot Offset Switch” in Chapter 3. After you reinstall the power supply, cycle power. Application Advisory After correcting configuration, controller, or installation problems, be sure that the configuration is sent to the adapter. One way to do this is to cycle power to the adapter and modules. This will generally force the controller to transfer configuration to the adapter. 5. Verify the connection of the 1701 terminal base to FlexBus. See Chapter 3, Installation. Check for bent pins in the Flex male connectors. Replace any bad parts, cycle power to the adapter and the FieldMonitor system, and recheck. If none of the above solves the problem, then you may have a faulty module, terminal base, or adapter. The likelihood of this is low and you should make sure you have adequately explored configuration and installation before pursuing these possibilities. 1. If you cannot communicate to a particular 1701 monitor, then replace it with a monitor of the same type and cycle power to the adapter and the FieldMonitor system. 2. If none of the monitors in any slot in the terminal base can be made to communicate, then replace the terminal base. 9.2 Monitor Troubleshooting 142 This section shows how to interpret fault information from the monitors status word and LED. Information here applies to the 1701/15 Proximitor Input Monitor, the 1701/25 Seismic Input Monitor and the 1701/30 Dynamic Pressure Monitor. Section 9 - Troubleshooting 9.2.1 Monitor LED Fault Conditions STATUS LED OFF Conditions Power is off, LED is defective, monitor is defective, or power supply is defective Green flashing at 1 Hz Monitor is communicating on Flexbus but is not configured. Green steady Monitor is configured and monitor and transducers are OK. One or both channels are in Alarm. Recoverable fault such as: one or both transducers are Not OK, Monitor is in Timed OK Channel Defeat, the monitor is Not OK, or the configuration is not valid Alternate green/red flashing Red flashing at 1 Hz Alternate 5 Green and 1 Red flashing at 1 Hz Communication problem between the Monitor and the Flex Adapter. Red steady Non-recoverable fault Indicated Actions Verify that the power supply OK LED is on. Verify that the monitor is installed correctly and there is not a field wiring fault. If the problem persists replace the monitor Cycle power. Verify that the configuration is correct for the slot and module type. See “Communication Problems” above. Module is operating normally. Read the monitors Monitor Read Status Word to determine the specific condition. See the section below for configuration faults. A common fault is transducer field wiring is faulted or transducer I/O module is not installed. Ensure that the Terminal Base Flex connector is properly attached to the Adapter and that there are no bent pins in the Adapter. See Appendix I. Cycle power. If the problem persists, check the entire system. Replace the module. 143 FieldMonitor Machinery Protection System Operation Manual 9.2.2 Monitor Status Codes The 1701 returns monitor status in bits 12, 13, 14, and 15 of the Read Status Word, word 5, in the I/O data table for the 1701/15, 1701/25 and 1701/30 monitors.

The 1701/15 and 1701/25 monitors will check certain configuration options for compatibility and return a configuration fault status if incompatible options are detected. The monitors check the following configuration options: Monitor Internal Compatibility Check Comments Transducer vs. barrier option Certain transducer types are not approved for use with safety barriers or certain types of safety barriers. Transducer selections on the two channels are compatible When using Dual Internal Proximitor Modules both channels must be configured as the same type. If one channel is configured as a 3000 series -18 volt Proximitor Sensor then the other channel must be the same. Transducer vs. full-scale range vs. trip multiply Certain transducer types have range limitations. Setpoints are in range Direct setpoints must be in the range of 0 to 200. This is a boundary check. Over/Under setpoints are not crossed Over and Under setpoints must not be crossed. The over setpoint must be greater than the under setpoint. Selected filter option codes are valid choices Filter option tables contain reserved codes that cannot be selected. Velocity channel filter corner frequencies are at least 2 octaves apart For velocity channels it is possible to set high-pass and low-pass filters close enough together to degrade passband performance. High-pass filter selection for 1701/25 channels is compatible with signal processing For Velocity channels configured for rms or integration and Acceleration channels configured for rms, the highpass corner can be no lower than 10 Hz. Acceleration channels configured for integration cannot have a highpass corner below 20 Hz 1701/25 full-scale range vs Acceleration Monitor Type The 1701/25 Seismic Input Monitor can be configured for three types of Acceleration Input Monitor. A type 1 acceleration monitor does not allow integration on either channel. 145 FieldMonitor Machinery Protection System Operation Manual Tables showing option compatibility can be found using the table below.
