Common Applications
Product Precautions
WESTINGHOUSE 1C31197G05 identifies the DC-LVDT personality option within the Ovation valve-positioner family. Its field wiring, feedback polarity and electronics pairing must remain tied to the installed actuator and control strategy.
- Valve-positioner personality module
- Fused 24 VDC LVDT interface
- 50 mA LVDT rating
- 1C31194G01 or 1C31194G02 electronics pairing
The installed signal path is Position demand → 1C31194 electronics → 1C31197G05 LVDT and servo interface → Electro-hydraulic valve actuator. Record the as-left channel assignment and verify the affected path before release.
Important Notice: Hydraulically isolate the actuator and establish the approved valve safe state before handling WESTINGHOUSE 1C31197G05.

WESTINGHOUSE 1C31197G05 Official Technical Reference Excerpt (PDF)WESTINGHOUSE 1C31197G05 Installation & Commissioning Guide (PDF)
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 1C31197G05.
Governor-valve positioning
Interfaces the installed electro-hydraulic actuator and DC LVDT feedback.
Interceptor-valve control
Supports the documented valve-positioner loop when the complete subsystem matches.
Extraction or bypass valve service
Provides the G05 feedback personality for an approved Ovation valve application.
Position-loop maintenance
Supports controlled checks of demand, LVDT feedback, servo response and local indication.
Apply these controls to WESTINGHOUSE 1C31197G05 before isolation, removal, reconnection, energization and release.
1
Hydraulically isolate the actuator and establish the approved valve safe state before handling WESTINGHOUSE 1C31197G05.
2
Verify the complete G05 identity and the paired 1C31194G01 or G02 electronics module.
3
Record LVDT wiring, servo-coil wiring, polarity, shields and all position-loop settings before removal.
4
Confirm the installed feedback device is the documented fused 24 VDC, 50 mA DC LVDT arrangement.
5
Do not disturb mechanical valve linkage or LVDT alignment without a controlled calibration procedure.
6
Inspect the fuse and field wiring for a root cause before replacing a fuse or reapplying excitation.
7
Commission at controlled travel limits while comparing demand, measured feedback and actual valve position.
8
Prove seating, retreat, local/remote control and the configured fault response before returning the valve to automatic service.
Technical notes
WESTINGHOUSE 1C31197G05 is an Ovation valve-positioner personality module for a fused 24 VDC LVDT feedback circuit rated at 50 mA.
