Information
Overview
Manuals
Common Applications
Product Precautions
WESTINGHOUSE 1C31189G03 is used where Ovation must calculate and supervise rotating-equipment speed. Sensor type, pulses per revolution, direction, alarm points and relay logic must be reconciled before the module is returned to service.
- 32-bit high-resolution speed
- 0.089-30000 Hz measurement range
- Acceleration and overspeed processing
- 1C31192G01 personality pairing
The installed signal path is Speed sensor → 1C31192G01 personality module → 1C31189G03 processing → Ovation speed and trip logic. Record the as-left channel assignment and verify the affected path before release.
Important Notice: Place the machine and related trip logic in the approved safe condition before handling WESTINGHOUSE 1C31189G03.

The Technical Reference presents the applicable model data and interface details; the Installation & Commissioning Guide organizes field preparation, controlled replacement and acceptance checks for WESTINGHOUSE 1C31189G03.
Turbine speed monitoring
Measures rotating speed and acceleration for Ovation logic.
Overspeed supervision
Provides configured overspeed and latched-overspeed point types.
Sensor-circuit diagnostics
Supports open-wire and input-status checks.
Legacy speed-channel replacement
Restores an installed G03 enhanced speed-detector position.
Apply these controls to WESTINGHOUSE 1C31189G03 before isolation, removal, reconnection, energization and release.
1
Place the machine and related trip logic in the approved safe condition before handling WESTINGHOUSE 1C31189G03.
2
Confirm the complete G03 identity and 1C31192G01 personality-module pairing.
3
Record pulses per revolution, scale, direction, alarm points and relay logic before removal.
4
Verify sensor gap, cable shield, polarity and field continuity before installing the replacement.
5
Do not copy settings from a nearby speed channel without an approved channel record.
6
Test open-wire behavior separately from normal speed measurement.
7
Prove speed and acceleration with a traceable frequency source across representative points.
8
Complete overspeed and latched-relay acceptance only under the plant-approved protection test procedure.
Technical notes
WESTINGHOUSE 1C31189G03 is an Ovation enhanced speed-detector electronics module for high-resolution frequency, speed, acceleration and overspeed processing.
