Operation Procedure for Bently Nevada 3500/40M-01-00 Proximitor Monitor Module

1. Pre-operation Preparation

Verify normal operation of the 3500 system rack and stable 24 VDC backplane power supply.

Inspect proximity probes, extension cables and proximitor assemblies for sound insulation, free of short-circuit or open-circuit faults.

Get 3500 Rack Configuration Software, calibration tools and related technical documentation ready.

Follow lock-out-tag-out requirements before performing module plug-in/out or any wiring work.

2. Hardware Installation

Insert the 3500/40M-01-00 module into an available slot 2-14 on the 3500 rack and push it fully to achieve reliable backplane connection.

Route proximitor output signal cables to the corresponding rear-panel I/O terminals. Implement single-end shielding grounding at the cabinet ground bar.

Torque all terminal screws properly to prevent loose connections.

Power up the rack and observe front-panel LED indicators. Normal initialization is indicated by a steady green OK light.

3. Software Configuration

Open 3500 Rack Configuration Software and establish communication connection with the target rack.

Choose the physical slot assigned to 3500/40M-01-00. Configure paired-channel functions including radial vibration, thrust position, differential expansion, eccentricity or REBAM.

Set transducer sensitivity, measurement range, filter parameters and OK/Not-OK fault delay.

Define Alert and Danger alarm thresholds, and select latching or non-latching alarm behavior.

Set 4-20 mA analog output scaling for each channel if data transmission to DCS is needed.

Save the project file and download the full configuration to the rack, then wait for download completion.

4. Calibration & Signal Verification

Inject standard calibration signals at 0 %, 50 % and 100 % of full-scale range by calibration equipment.

Compare module readings with reference input values to ensure measurement error stays within technical specifications.

Review raw signal waveform in configuration software and confirm no excessive noise or signal distortion.

Validate Not-OK fault response by simulating sensor open-circuit and short-circuit conditions.

5. Alarm & Interlock Function Test

Feed simulated out-of-range signals to trigger Alert and Danger thresholds separately.

Confirm alarm indications on module front panel, rack interface unit, relay modules and upstream DCS/SCADA system.

Execute alarm reset tests via rack-interface push-button, software commands or remote dry-contact signals.

Verify proportional variation of 4-20 mA analog output corresponding to measured quantities.

6. On-Site Commissioning with Actual Machinery

Complete gap adjustment for proximity probes mounted on rotating equipment.

Monitor real-time readings after unit startup; confirm vibration, thrust position and other process parameters remain within normal operating limits.

Keep tracking channel OK status. Resolve fluctuations caused by inadequate shielding or improper grounding.

Document commissioning records and complete acceptance according to API-670 requirements.

7. Daily Operation & Routine Maintenance

Periodically check front-panel LED status: steady green OK means healthy condition; red Not-OK points to sensor-loop or module failure.

Regularly check rear-terminal tightness and cable integrity.

Perform drift calibration every 12-month interval.

For hot-swap replacement in redundant systems: remove defective module, install spare unit with matching firmware version and download corresponding configuration.

Capture fault logs via 3500 configuration software or System 1 for subsequent troubleshooting.

8. Shutdown & De-commissioning

Obtain work permit and deactivate associated interlock protection logic prior to module removal.

Isolate relevant signal loops; power down the rack if required and extract the module from its slot.

Disconnect field sensor wiring and clearly label cables for future reuse.

Calibration Procedure for Bently Nevada 3500/40M-01-00

Recommended tools: Bently TK-3 / TK-8 calibrator, DC signal source, multimeter, 3500 Rack Configuration Software, calibration record sheet.

Safety requirements: Obtain work permit; bypass interlocks if necessary; perform LOTO lock-out-tag-out before power-off and wiring disconnection.

1. Pre-calibration Preparation

1. Confirm stable 24 VDC backplane power supply for the 3500 rack and steady green OK LED on the module.

2. Connect PC to the rack, launch 3500 Rack Configuration Software, upload the active online configuration and back-up the project file.

3. Disconnect field proximitor output signal wires and connect calibration equipment to corresponding channel terminals. **Do not plug or unplug field proximitor wiring while powered on.

4. Verify channel parameters: transducer sensitivity, measurement range, function mode (radial vibration, thrust position, differential expansion), filter settings and alarm thresholds.

2. Static Accuracy Verification (Simulate Proximitor Gap Voltage)

1. Use signal source to output DC voltage simulating proximitor gap voltage. Apply input signals corresponding to 0 %, 25 %, 50 %, 75 % and 100 % of full-scale range.

2. Observe channel bar-graph and numerical readings in configuration software. Record standard input values and module displayed values.

3. Acceptance criteria: measurement error ≤ ±1 % FS.

4. In case of large deviation: inspect the complete set of probe-extension-cable-proximitor first. Only the software scale factor can be adjusted; no hardware zero-point or gain trimming is supported.

5. Software zero-point adjustment

Go to Channel-Transducer-Customize and enter gap voltage corresponding to mechanical zero-point. Download updated configuration to rack.

This is a display zero-point only and cannot compensate inherent linear drift of physical transducers.

3. Dynamic Vibration Signal Verification (Vibration Channels)

1. Set calibrator to output standard AC vibration signals at 0 %, 50 % and 100 % amplitude with specified frequency.

2. Read overall vibration and 1X amplitude from the module. Measured values shall comply with technical specifications compared with reference inputs.

3. Confirm waveform without distortion or abnormal noise.

4. OK / Not-OK Loop Fault Verification

1. Simulate sensor open-circuit: disconnect input wiring. Confirm Not-OK red LED illuminates and channel fault alarm appears in software.

2. Simulate sensor short-circuit: short-circuit signal terminals. Confirm Not-OK alarm is triggered.

3. Restore wiring, verify fault can be cleared and OK green LED returns to normal status.

5. Alarm Threshold Verification (Alert / Danger)

1. Slowly adjust input signal slightly above Alert setpoint. Confirm alarms are indicated on module front panel, configuration software, relay modules and DCS side.

2. Further increase signal slightly above Danger threshold and verify danger alarm activation.

3. Test alarm reset via rack push-button or software remote command; distinguish between latched and non-latched alarm modes.

4. Reduce signal back to normal range and check alarm status resets accordingly.

6. 4-20 mA Analog Output Verification

1. Connect multimeter in series with 4-20 mA loop. Ensure external load resistance ≤600 Ω.

2. Apply 0 % full-scale input: output shall be 4 mA; 50 % corresponds to 12 mA; 100 % corresponds to 20 mA.

3. Log measured current values. Error ≤ ±0.16 mA is acceptable. If deviation occurs, check analog scaling parameters in software.

7. Reconnect Field Transducers and Overall Check

1. Disconnect calibration instruments and restore field proximitor wiring. Ensure single-end shielding grounding at cabinet ground bar.

2. Measure actual gap voltage, confirm it lies within transducer linear range (typically -9 V ~ -11 VDC).

3. Monitor real-time channel readings in software; values shall be stable without fluctuation or Not-OK alarms.

4. Download and confirm final configuration, save project file and complete calibration documentation.

5. Restore interlock protection functions in accordance with work permit upon completion.
