1. Product Overview
Bently 3500/22m is a vibration monitoring module launched by Bently Nevada. It is part of the 3500 series monitoring system and is mainly used for vibration monitoring and protection of mechanical equipment. The module can receive signals from eddy current sensors or accelerometers, provide accurate vibration measurement data, and issue an alarm when the preset threshold is exceeded to protect key equipment from damage.
2. Preparation before installation
1. Preparation of tools and materials
3500/22m module
3500 frame (such as 3500/15)
Special installation tool kit
Anti-static wristband
Digital multimeter
Signal generator
Special connection cable
Grounding wire
System configuration software (System 1 or related configuration tools)
2. Safety precautions
Ensure that the work area is clean and dry
Comply with all electrical safety regulations
Disconnect all power before installation
Use anti-static measures to protect electronic components
Confirm that all connectors match the interface
3. Hardware installation steps
1. Rack installation
Install the 3500 frame (such as 3500/15) in the reserved position in the control cabinet
Ensure that the frame is firmly fixed and leaves enough space for heat dissipation
Confirm that the frame is well grounded (the grounding resistance should be less than 1Ω)
2. Module installation
Wear an anti-static wristband
Remove the 3500/22m module from the anti-static packaging
Align the module with the rails on the frame
Push the module in smoothly until it is fully seated
Tighten with the module fixing screws
3. Electrical connection
Power connection:
Connect redundant power supply (if used)
Confirm that the power supply voltage meets the requirements (usually 24VDC)
Measure the stability of the power supply voltage (the fluctuation should be less than ±5%)
Sensor connection:
Connect the vibration sensor cable to the specified terminal
Confirm that the sensor type matches the module configuration
Check the grounding of the cable shield
Communication connection:
Connect the frame backplane communication interface
Configure the network connection (if used)
IV. Software configuration
1. Basic parameter settings
Use the configuration software to connect to the 3500 system
Select the 3500/22m module for configuration
Set basic parameters:
Module name/ID
Sensor type (eddy current/accelerometer)
Measurement range
Engineering unit
2. Alarm threshold setting
Configure alarm level (warning/danger)
Set each alarm threshold
Configure alarm delay time
Set alarm logic (and/or)
3. Signal processing setting
Select filter parameters
Set sampling frequency
Configure signal processing algorithm
Set dynamic range
V. System debugging
1. Static test
Check the power indicator status
Verify module and framework communication
Check whether the configuration parameters are saved successfully
Test the alarm output relay function
2. Dynamic test
Use signal generator to simulate sensor signal
Input standard sine wave signal
Verify the accuracy of measurement value
Test the triggering of each alarm threshold
Actual sensor test
Connect actual sensor
Observe signal waveform
Verify dynamic response characteristics
3. System integration test
Test communication with DCS/PLC
Verify host computer data display
Test historical data recording function
Check alarm interlocking function
VI. Common problem handling
1. Module cannot be recognized
Check whether the module is installed in place
Verify framework power supply
Check backplane communication connection
2. Inaccurate measurement value
Check sensor calibration
Verify signal wiring
Check grounding
Reconfigure measurement parameters
3. False alarm
Check alarm threshold settings
Check signal interference
Adjust filter parameters
Check sensor installation
VII. Maintenance recommendations
Regularly check module operation status
Regularly verify measurement accuracy
Keep system software updated
Regularly check grounding system
Establish complete maintenance records
VIII. Safety precautions
Power must be turned off before any maintenance operation
Back up current configuration before modifying parameters
Do not change factory default settings at will
Set obvious signs when debugging the system
Follow all local safety regulations
