The Bently Nevada 3500/40M-01-00 is a four-channel Proximitor Monitor designed for the 3500 Machinery Protection System. Its primary function is to process signals from proximity transducers, providing continuous, real-time machinery protection. It specifically measures radial vibration, shaft eccentricity, and axial thrust position. By comparing these processed signals against user-programmable alarm setpoints, the monitor can drive machinery protection credit and initiate emergency shutdowns when critical thresholds are exceeded.
This "M" version (Proximitor Monitor) is part of the 3500/40 series and is configured with the 01 I/O module type, which specifies Internal Terminations. This design is intended for use in high-density installations where field wiring is connected directly to the backplane of the 3500 rack. The module occupies one slot in the 3500 rack and communicates with the 3500/22M Transient Data Interface (TDI) for advanced diagnostics and data collection.

When procuring 3500 series components, the combination of the main monitor and the I/O module is critical. The 3500/40M-01-00 consists of:
| Component | Part Number | Description |
| Main Module | 140734-01 | 3500/40M Proximitor Monitor Module |
| I/O Module | 125680-01 | Proximitor I/O Module with Internal Terminations |
The 01 I/O module provides internal terminations. Field wiring from the Proximitor sensors is connected to the 10-pin terminal blocks on the I/O module at the rear of the rack.
Wiring Architecture:
A-B-C Terminals: Used for Power (-24Vdc), Signal (SIG), and Common (COM) connections for each of the four channels.
Shielding: Field cable shields must be terminated at the 3500 rack to ensure EMI/RFI protection.
Recorder Outputs: 4 to 20 mA DC proportional outputs are available for each channel on the I/O module to interface with external DCS or PLC systems.
Internal Termination Precautions:
The "01" option utilizes internal terminations, meaning field wiring is connected directly to the I/O module. Unlike external termination (ET) blocks, this does not allow for a "marshalling" style disconnection between the rack and the field. Ensure sufficient cable slack is available in the cabinet for rack removal during maintenance.
Channel Configuration:
Channels are configured in pairs (1 & 2, 3 & 4). Each pair can be set for different measurement types (e.g., Channels 1 & 2 for Radial Vibration, Channels 3 & 4 for Axial Thrust). Configuration must be performed via the 3500 Rack Configuration Software.
Power and Grounding:
To maintain signal integrity, the 3500 system must be connected to a dedicated instrument ground. Avoid sharing ground paths with high-voltage machinery or VFDs. The Proximitor Monitor receives its power from the 3500/15 Power Supply; ensure the rack power budget is not exceeded when adding additional 3500/40M modules.
Hot Swapping:
The 3500/40M module is "hot-swappable" under most conditions. However, removing the module will trigger a "Not OK" status for all four channels and may initiate a relay trip if the system logic is set for "OR" voting. Always place the associated protective loops in bypass or maintenance mode before hardware removal.
Q: What is the difference between the 3500/40M and the 3500/42M?
A: The 3500/40M is a dedicated Proximitor Monitor. The 3500/42M is a "Proximitor/Seismic" monitor, which is more versatile as it can accept signals from both proximity probes and seismic transducers (accelerometers/velometers).
Q: Can I use this monitor with 3300 XL Proximitors?
A: Yes. The 3500/40M is compatible with standard 5mm, 8mm, and 11mm 3300 and 3300 XL proximity transducer systems.
Q: How do I resolve a "Not OK" LED?
A: A "Not OK" status indicates a hardware fault or a field wiring problem (open or short circuit). Check the DC gap voltage at the I/O module. If the voltage is between -2V and -18V, the field string is likely healthy and the fault may lie within the module configuration or the module itself.
Q: Is the configuration stored on the module?
A: No. The configuration is stored in the 3500/22M TDI (Rack Interface Module). When a new 3500/40M is inserted, the TDI automatically downloads the correct configuration to the module.
