      Information

      Overview Manuals Common Applications Product Precautions
      Bently Nevada 3500/45 176449-04 is a four-channel position monitor for the 3500 rack. It conditions proximity, LVDT, RPT or rotary-potentiometer inputs into position variables used for alarms, trends and machine-protection logic.
      • Conditions up to four position-transducer inputs for machinery protection
      • Supports thrust, differential expansion, case expansion and valve-position duties
      • Generates measured variables for independent Alert and Danger comparisons
      • Provides individual current recorder outputs for supported channel configurations

      3500/45 176449-04 installs with 3500 rack, approved 3500/45 rear I/O module, Proximitor, RPT, DC/AC LVDT or rotary potentiometer, 3500 Rack Configuration Software in an engineered 3500 Machinery Protection System configuration.

      The commissioning workflow covers installed-hardware matching, controlled start-up and functional verification for this 3500/45 position monitor.

      Important Notice: Confirm the complete 3500/45 176449-04 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

      Read the applicable Bently Nevada installation instructions before work. Verify 3500/45 176449-04 and the installed 3500 Machinery Protection System configuration.
      1Match 176449-04 to the documented 3500 front slot and rear I/O execution.
      2Isolate transducer excitation and recorder loops before removing the monitor.
      3Record the configured measurement type and transducer sensitivity for every active channel.
      4Use ESD controls and protect the buffered-output and backplane connectors.
      5Confirm the selected rear I/O module supports the installed transducer family.
      6Restore channel full scale, Alert/Danger setpoints and programmed time delays.
      7Check zero, span and recorder-current scaling with a controlled position input.
      8Prove alarm and shutdown logic before returning the monitored machine to service.

      Technical notes

      Restore each channel pair with the documented transducer type, sensitivity and full-scale range. Confirm excitation, recorder-loop scaling and Alert/Danger timing with controlled position simulation before the protection channel is armed.

      FAQ View All FAQ

      • Which rear I/O module can be paired with 3500/45 176449-04?
        Select the 3500/45 I/O execution that matches the installed Proximitor, RPT, DC LVDT, AC LVDT or rotary-potentiometer transducer and termination arrangement.
      • How many inputs can 3500/45 176449-04 condition?
        The monitor accepts one to four position-transducer inputs, configured according to the selected measurement application.
      • Which measurement duties can 3500/45 176449-04 perform?
        The official datasheet covers thrust position, differential expansion, ramp differential expansion, complementary input differential expansion, case expansion and valve position.
      • What recorder signal is available from 3500/45 176449-04?
        Supported channel configurations provide a 4–20 mA recorder output proportional to the monitor full scale.
      • How are alarm delays configured on 3500/45 176449-04?
        Use 3500 Rack Configuration Software to set Alert and Danger delays within the ranges published for the monitor.
      • What must be recorded before replacing 3500/45 176449-04?
        Capture channel type, transducer sensitivity, full scale, setpoints, delays, recorder scaling and the paired rear I/O part number.
      • How is a new 3500/45 176449-04 validated?
        Apply a controlled position input, confirm zero and span, compare the recorder loop, and prove Alert/Danger logic for each active channel.
      • Can 3500/45 176449-04 settings be copied from another position monitor?
        Only restore an approved configuration for the same transducer, I/O module and machine measurement duty; do not transfer unrelated channel settings.
