      Information

      Information

      Overview Manuals Common Applications Product Precautions
      Installed behind the matched reciprocating-compressor monitor, this I/O assembly brings cylinder-pressure channels into the protected 3500 measurement path.
      • Provides internal termination for reciprocating-cylinder pressure inputs
      • Feeds conditioned transducer signals to the paired 3500/77M monitor
      • Supports the monitored chamber measurements used for compressor protection
      • Keeps the pressure I/O connection within the 3500 rack architecture

      Install 143729-01 in the rear I/O position paired with the correct 3500/77M monitor and use only its internal termination headers. Verify transducer polarity, channel scale data and the required monitor firmware and configuration-software revisions before enabling alarms.

      Important Notice: Confirm 143729-01, the paired 3500/77M front module, rear-slot position, internal headers, approved pressure-transducer scale and polarity, rack grounding, firmware/software revisions and alarm functional testing before commissioning.

      Apter Power 143729-01 Manuals and Guides

      The first document is a model-specific engineering data reference. The second is a distinct installation and commissioning workbook with field checks and acceptance records.

      Reciprocating-compressor cylinder monitoring
      Connects cylinder pressure transducers used for chamber pressure measurements.
      Suction and discharge pressure supervision
      Supports monitor calculations used to observe pressure behavior across the compressor cycle.
      Rod load protection calculations
      Provides input data used by the monitor's peak compression, peak tension and reversal calculations.
      Compressor alarm commissioning
      Supports channel configuration and alarm testing for a 3500/77M protection installation.
      Read the applicable Bently Nevada installation information before work. Verify 143729-01 and the installed 3500/77M Cylinder Pressure I/O Module with Internal Terminations configuration before isolation, wiring or commissioning.
      1
      Verify the complete 143729-01 marking and its assigned 3500/77M channel group.
      2
      Place the rack and connected pressure circuits in the approved maintenance state.
      3
      Use ESD-safe handling for the rear I/O module and connector headers.
      4
      Do not connect external termination blocks to this internal-termination module.
      5
      Confirm the eight-pin and three-pin internal headers are correctly seated.
      6
      Verify each approved pressure transducer's two-point scale information and polarity.
      7
      Check required 3500/77M firmware and configuration software before download.
      8
      Prove channel values, buffered outputs and configured alarms before returning protection service.

      Technical notes

      Install 143729-01 in the rear I/O position paired with the correct 3500/77M monitor and use only its internal termination headers. Verify transducer polarity, channel scale data and the required monitor firmware and configuration-software revisions before enabling alarms.

      FAQS

      • Which monitor uses 143729-01?
        It is the internal-termination Cylinder Pressure I/O Module for the 3500/77M monitor.
      • Does 143729-01 use internal or external terminations?
        This part uses internal terminations; the official documentation states external termination blocks cannot be used with internal-termination I/O modules.
      • What transducer inputs are intended for 143729-01?
        It accepts Bently-approved positive-voltage pressure transducers used for cylinder-pressure measurements.
      • What connector headers are listed for 143729-01?
        The spares list identifies an eight-pin and a three-pin internal I/O connector header used on this module.
      • What rack position is required for 143729-01?
        The I/O module occupies the full-height rear slot associated with the front monitor module.
      • What configuration data should be checked for 143729-01?
        Verify transducer two-point pressure/voltage data, channel assignment, measured variables and alarm setpoints.
      • What software baseline applies when commissioning 143729-01?
        The 3500/77M documentation specifies minimum firmware and software revisions that must be met or exceeded.
      • How should replacement of 143729-01 be verified?
        Record the original headers and channel wiring, install the module under isolation, restore the configuration and test pressure values and alarms.
