Product Precautions
Westinghouse 1C31147G01 counts two medium-speed pulse channels for frequency, accumulated-count or pulse-duration functions in the Ovation system.
- Provides two accumulator channels for the documented pulse accumulator electronics module function.
- Handles medium-speed pulse and control input through the specified Ovation I/O subsystem.
- Works with application-matched 1C31150G01-G03 personality module.
- Each channel can use the external count input or the module timebase according to the controlled configuration.
The pulse accumulator electronics module belongs in the controlled Ovation I/O subsystem and works with application-matched 1C31150G01-G03 personality module. Its field connection, companion hardware and project configuration must be reviewed together before the channel is returned to service.
Important Notice: Use 1C31147G01 only with application-matched 1C31150G01-G03 personality module; verify the field interface and controlled configuration before energizing the subsystem.

Westinghouse 1C31147G01 Official Technical Reference Excerpt (PDF)Westinghouse 1C31147G01 Installation & Commissioning Guide (PDF)
The first document covers the product function, system role and technical selection. The installation guide covers identification, connection checks, commissioning and the acceptance record.
Installed-base maintenance
Restores the documented pulse accumulator electronics module position without changing the approved system architecture.
Loop or channel service
Supports verification of medium-speed pulse and control input at the assigned control-system channel.
Planned replacement
Provides an exact-identity replacement path when application-matched 1C31150G01-G03 personality module and the field interface have been confirmed.
Commissioning support
Allows the responsible engineer to prove wiring, configuration, status and response for two accumulator channels.
Before installing Westinghouse 1C31147G01, confirm the documented system, interfaces and controlled configuration.
1
Match the complete 1C31147G01 marking to the work order and installed position before removal.
2
Confirm application-matched 1C31150G01-G03 personality module before making or breaking any field connection.
3
Keep the assigned medium-speed pulse and control input within the documented subsystem and range.
4
Record terminal designations, polarity, common and shield treatment before disconnecting conductors.
5
Inspect module seating, connector keying, terminal condition and strain relief before power is restored.
6
Restore the controlled channel configuration, range selection and alarm or timeout behavior after installation.
7
Check local indicators and controller diagnostics for internal, communication or channel faults during commissioning.
8
Prove the intended response across two accumulator channels and record the acceptance result before release.
Technical notes
Use 1C31147G01 only with application-matched 1C31150G01-G03 personality module; verify the field interface and controlled configuration before energizing the subsystem.
FAQ View All FAQ
-
Which measurement functions are available on Westinghouse 1C31147G01?Each of the two channels can be configured for frequency, accumulated count or pulse-duration measurement.
-
What input-level families are documented for Westinghouse 1C31147G01?The medium-speed executions cover 24/48 V and 5/12 V input levels through the appropriate personality interface.
-
How many pulse accumulators operate in Westinghouse 1C31147G01?The electronics module contains two independently assigned pulse-accumulator channels.
-
Which personality modules can complete Westinghouse 1C31147G01?The documented choices are 1C31150G01, 1C31150G02 and 1C31150G03, selected for the required field circuit.
-
Can Westinghouse 1C31147G01 count from an external source or an internal timebase?Yes. The controlled channel configuration can use an external count input or the module timebase.
-
What status indications help diagnose Westinghouse 1C31147G01?Channel-enable, external-fault and internal-fault indications are provided for the pulse-accumulator subsystem.
-
Why must the voltage execution be matched before connecting Westinghouse 1C31147G01?A 24/48 V pulse circuit and a 5/12 V circuit require the corresponding personality-module arrangement to present the correct input interface.
-
How should Westinghouse 1C31147G01 be tested for accumulated-count service?Apply a known pulse sequence to each configured channel and compare the Ovation accumulated value while monitoring enable and fault status.
