Cylinder Pressure Signal Interface
The 143729-01 handles the physical interface between the specified field pressure transducer wiring and the 3500/77M cylinder pressure monitoring arrangement. Internal terminations route the connected transducer signals through the module’s designated connector interfaces.
The documented connector configuration includes one eight-pin Euro Style header, 00580434, and one three-pin Euro Style header, 00580441. The listed alternatives are 166M2389 for the eight-pin connector and 166M4363 for the three-pin connector.
The module itself should not be treated as the complete cylinder pressure measurement system. Pressure measurement, monitoring logic, and system-level processing belong to the associated 3500/77M monitoring assembly.
Frequently Asked Questions
Q: Is 143729-01 the complete 3500/77M cylinder pressure monitor?
A: No. The 143729-01 is the cylinder pressure interface module with internal terminations. It is separate from the front-mounted cylinder pressure monitor.
Q: Which pressure transducers can connect to 143729-01?
A: The module is specified for Bently-approved third-party pressure transducers. The exact transducer type should be verified against the installed 3500/77M configuration.
Q: Which connector headers are specified for this module?
A: The documented configuration includes 00580434 Euro Style for the eight-pin header and 00580441 Euro Style for the three-pin header. The corresponding alternatives are 166M2389 and 166M4363.
Field Installation Guidelines
- Verify the module part number before installation.
- Confirm that the connected pressure transducer is an approved type for the 3500/77M arrangement.
- Verify the required internal termination arrangement before connecting field wiring.
- Match the field wiring to the specified eight-pin and three-pin connector headers.
- Confirm connector keying, pin assignment, and terminal identification against the applicable system documentation.
- Route pressure-transducer wiring separately from high-current power conductors where practical.
- Maintain cable shielding and grounding according to the applicable Bently Nevada installation documentation.
- Inspect connector seating and termination integrity before system energization.
- Do not assign standalone cylinder pressure measurement functions to the interface module itself.
