The Bently-Nevada 3500/42-05-01 module is a Proximitor/Seismic Monitor (seismic vibration recording module/data recording module) in the Bently-Nevada 3500 machine protection system. The primary use of this module is to record mechanical behavior indicators of rotating mechanical equipment that include vibration, shaft displacement, axial displacement, speed, and acceleration. It is a vital component of industrial equipment condition monitoring as well as mechanical protection systems.
1. Install the module into the 3500 rack.
2. Connect the I/O module.
3. Connect the sensor signal lines.
4. Use the 3500 configuration software to set the parameters.

Product Details
The Bently Nevada 3500/42-05-01 model, in its standard configuration, typically includes two parts: the front card (Monitor Module) and the rear card (I/O Module).
--Front Card (Monitor Module)
Installed at the front of the 3500 rack
Main responsibilities:
Vibration signal processing
Data calculation and monitoring
Alarm logic judgment
Communicate with the system
--Rear Card (Rear I/O Module)
Installed at the rear of the rack
Main functions:
Connect the sensor signals
Provide terminal wiring
Transmit the signal to the front card for processing
Interact with other modules of the system
How to check the Proximitor/Seismic Module through the panel indicator lights
The general approach for testing OK limits is to input a DC voltage and adjust it above the Upper OK limit and below the Lower OK limit. This will cause a channel not OK condition, and the OK Relay will change state (de-energise). The Upper and Lower OK limits are displayed in the Verification screen on the test computer.
1. Disconnect PWR, COM, and SIG field wiring from the channel terminals on the I/O module.
2. Connect test equipment and run software as described in Section 5.1.5.1 (Test Equipment and Software Setup - Radial Vibration).
3. Bypass all other configured channels.
4. Adjust the power supply voltage to -7.00 Vdc.
5. Press the RESET switch on the Rack Interface Module (RIM). Verify that the monitor OK LED is on and that the Channel OK State line in the Channel Status box of the Verification screen displays 'OK'.
6. Verify that the OK relay on the Rack Interface I/O Module indicates OK(energised). See 3500/20 Rack Interface Module Operation and Maintenance Manual, part number 129768-01.
7. Increase the power supply voltage (more negative) until the OK LED just goes off (upper limit). Verify that the Channel OK State line in the Channel Status box reads not OK and that the OK Relay indicates not OK. Verify that the Upper OK limit voltage displayed on the Verification screen is equal to or more positive than the input voltage.
8. Decrease the power supply voltage (less negative) to -7.00 Vdc.
9. Press the RESET switch on the Rack Interface Module (RIM). Verify that the OK LED comes back on and the OK relay energises. Verify that the Channel OK State line in the Channel Status box reads OK.
10. Gradually decrease the power supply voltage (less negative) until the OK LED just goes off (lower limit). Verify that the Channel OK State line in the Channel Status box reads not OK and that the OK Relay indicates not OK. Verify that the Lower OK limit voltage displayed on the Verification screen is equal to or more negative than the input voltage.
11. Increase the power supply voltage (more negative) to -7.00 Vdc.
12. Press the RESET switch on the Rack Interface Module (RIM). Verify that the OK LED comes back on, the OK relay energizes, and that the Channel OK State line in the Channel Status box reads OK.
13. If you can not verify any configured OK limit, go to Section 5.1.10 (If a Channel Fails a Verification Test).
14. Disconnect the test equipment and reconnect the PWR, COM, and SIG field wiring to the channel terminals on the Monitor I/O Module. Press the RESET switch on the Rack Interface Module (RIM) and verify that the OK LED comes on and the OK relay energises.
15. Repeat steps 1 through 14 for all configured channels
16. Return the bypass switch for all configured channels back to their original setting.

Procurement Suggestions
When purchasing item 3500/42-05-01, the following usually need to be confirmed:
1️⃣ Does it include the front card and the rear card?
2️⃣ Model of I/O module (Is it equipped with isolation?)
3️⃣ Does it come with terminal blocks?
4️⃣ Is it a complete set?
Many suppliers quote as follows:
Only report the previous card
Or, a separate I/O module
3500/42-05-01 is a complete monitoring module model. Under normal circumstances, it includes:
Front card (Monitor Module)
Rear Card (I/O Module)
Only when the two are combined can they form a complete and installable module component.
The general approach for testing OK limits is to input a DC voltage and adjust it above the Upper OK limit and below the Lower OK limit. This will cause a channel not OK condition, and the OK Relay will change state (de-energise). The Upper and Lower OK limits are displayed in the Verification screen on the test computer.
