      Overview Manuals Common Applications Product Precautions
      Bently Nevada 3500/46M 176449-06 is the documented four-channel hydro machinery monitor for the 46M product family.
      • Accepts one to four proximity, air-gap, velocity or acceleration sensor signals.
      • Provides hydro radial vibration, air gap, velocity, acceleration, thrust and dynamic-pressure functions.
      • Supports up to eight alarm parameter sets for configured multimode channels.
      • Switches machine-mode alarm sets through multimode I/O contacts or gateway commands.

      Install 3500/46M 176449-06 only with the documented 46M front/rear module, termination hardware, transducers and approved 3500 rack configuration. Commissioning covers identity, signal path, scaling, alarms and controlled response.

      Important Notice: Confirm the complete 3500/46M 176449-06 identity, installed interfaces, approved configuration and final functional acceptance record before service release.

      Important Notice: The first document presents exact-model technical data and engineering questions. The second provides a separate model-specific installation, configuration and acceptance workflow.

      Hydro radial vibration
      Combine shaft gap movement and NX amplitude for hydro-unit protection measurements.
      Hydro air-gap monitoring
      Condition compatible air-gap sensor signals for static and dynamic assessment.
      Multimode operation
      Select mode-specific alarm sets as operating state changes.
      Dynamic pressure and SEW
      Monitor configured pressure or stator-end-winding vibration inputs.
      Read the applicable Bently Nevada installation instructions before work. Verify 3500/46M 176449-06, its installed system arrangement and configured interfaces before commissioning.
      1
      Verify 176449-06 and the installed Hydro I/O type before replacement.
      2
      Confirm firmware and rack software meet the minimum revision for every configured hydro application.
      3
      Preserve each paired-channel configuration and the selected machine-mode logic.
      4
      Match every sensor to its documented sensitivity, polarity and power-supply type.
      5
      For external multimode termination, use the documented recorder ET block and signal cable 129525.
      6
      Do not mix external termination blocks with internal-termination I/O modules.
      7
      Prove mode changes and all applicable Alert/Danger sets with controlled conditions.
      8
      Record active mode, static values, alarms, buffered outputs and final acceptance results.

      FAQS

      • Which sensor families can 3500/46M 176449-06 accept for hydro monitoring?
        The Hydro Monitor accepts proximity, seismic, dynamic-pressure and air-gap sensor inputs; the installed I/O and channel type must match the sensor.
      • How many input channels are available to 3500/46M 176449-06?
        The monitor accepts one to four sensor signals and programs the channels in pairs.
      • Why does 3500/46M 176449-06 require a machine-mode verification during commissioning?
        A multimode channel can hold up to eight alarm parameter sets and select the applicable set through I/O contacts or communications commands.
      • What restriction applies to the Hydro Velocity function of 3500/46M 176449-06?
        The datasheet states Hydro Velocity is valuable for warning and diagnosis but is not suitable for automated machinery protection because of its low-frequency, high-amplitude event behavior.
      • Which termination rule is critical for external multimode use with 3500/46M 176449-06?
        Use the documented multimode recorder ET block and cable 129525; external termination blocks cannot be paired with internal-termination I/O modules.
      • What recorder-output envelope should be tested on 3500/46M 176449-06?
        Each channel provides 4-20 mA proportional to full scale with 0-600 Ohm load capability and a 100 ms or faster update.
      • Why must firmware and software revisions be checked for 3500/46M 176449-06?
        Minimum revisions differ by hydro application, so the configured measurement type must be compared with the ordering-considerations matrix.
      • Which evidence should close a multimode acceptance test for 3500/46M 176449-06?
        Record active mode, selected alarm set, static values, buffered and recorder outputs, Alert/Danger response and mode-transition behavior.
