      Information

      Overview Manuals Common Applications Product Precautions
      Bently Nevada 125680-01 is the internal-termination Proximitor I/O module for a 3500/40M monitor. It connects up to four proximity-transducer circuits to the rear of the machinery-protection rack.
      • Terminates up to four proximity-transducer circuits inside the 3500 rack
      • Routes conditioned probe inputs to the paired 3500/40M front monitor
      • Supplies the documented negative transducer excitation through the I/O assembly
      • Supports the monitor's vibration, position, eccentricity, expansion and REBAM channel types

      125680-01 installs with 3500 rack rear slot, 3500/40M 176449-01 monitor, Proximity probes and extension cables, Internal field-wiring connectors in an engineered 3500/40M Proximitor Monitor configuration.

      The commissioning workflow covers installed-hardware matching, controlled start-up and functional verification for this proximitor i/o module with internal terminations.

      Important Notice: Confirm the complete 125680-01 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

      Read the applicable Bently Nevada installation instructions before work. Verify 125680-01 and the installed 3500/40M Proximitor Monitor configuration.
      1Confirm 125680-01 and its assigned 3500/40M rear-slot position before disconnection.
      2De-energize the rack and isolate transducer wiring before removing internal connectors.
      3Label all four channel connectors so probe assignments cannot be interchanged.
      4Use ESD controls and inspect the internal-termination headers for bent or recessed contacts.
      5Do not connect an external termination block to the 125680-01 internal-termination execution.
      6Seat the rear I/O module and front monitor as the documented matched assembly.
      7Confirm negative transducer power and stable gap voltage before restoring channel alarms.
      8Prove each measurement path using the configured radial, thrust, expansion or REBAM duty.

      Technical notes

      Keep each probe, extension cable and Proximitor circuit assigned to its original channel, verify internal connector seating and measure stable gap voltage before enabling monitor alarms.

      FAQ View All FAQ

      • What as-found information should an engineer record before removing 125680-01?
        Record every channel or port assignment, connector identity, configured function, cable tag and diagnostic state associated with 125680-01.
      • How should 125680-01 be isolated before field wiring is disturbed?
        Place the protected machine in its approved maintenance state, isolate rack and field energy applicable to Proximity probes and extension cables, and prove the terminals safe before disconnection.
      • Which configuration should be restored after replacing 125680-01?
        Restore the approved 3500/40M Proximitor Monitor slot, channel or interface configuration and verify that every connected circuit retains its original assignment.
      • How can 125680-01 be commissioned for internal probe-circuit termination?
        Apply a controlled input or command, review the model-specific diagnostics and prove the expected measurement, indication and protection response before releasing the channel.
      • What technical value deserves special attention when checking 125680-01?
        Verify the published termination arrangement value of Internal against the installed configuration and test record.
      • Can 125680-01 be exchanged with another 3500 I/O or monitor execution?
        Only when the complete part number, termination style, transducer or interface type and approved rack configuration match the installed duty; do not transfer settings from an adjacent model.
      • What evidence should be retained after 125680-01 returns to service?
        Retain the full 125680-01 identity, as-left connections, restored configuration, final diagnostics and the controlled functional-test result for four-channel vibration rack assembly.
      • Which rack hardware must be matched before installing 125680-01?
        Match 125680-01 to the documented 3500 rack rear slot and 3500/40M 176449-01 monitor; confirm the front/rear slot pairing and the complete physical marking before connection.
