Features:
- Forms the TPD servo reference from P1 pressure and NHP speed inputs.
- Uses one LVDT for stop/speed ratio valve position feedback.
- Reports feedback and channel disagreement through FLT and the FAULT lamp.
IC3600SSVD1 coordinates gas-pressure and turbine-speed information at the stop/speed ratio valve control boundary.
The shutdown path on IC3600SSVD1 can suppress the TPD command independently of the normal regulator calculation.
Fault logic on IC3600SSVD1 covers single-channel feedback limits and the comparison used in a dual-channel arrangement.
The General Electric IC3600SSVD1 Stop/Speed Ratio Valve Control Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Signal Path
- Pressure branch: P1 enters the pressure path used by IC3600SSVD1.
- Speed branch: NHP passes through offset and gain conditioning on IC3600SSVD1.
- Control result: The comparison establishes the TPD reference for the servo regulator.
Shutdown
- Command: SR provides the shutdown logic input to IC3600SSVD1.
- Response: Logic 1 at SR forces TPD to zero.
- Boundary: This action is separate from the normal P1-versus-NHP calculation.
Feedback
- Position source: One LVDT closes the IC3600SSVD1 valve-position loop.
- Supervision: TPC, D and INH states are evaluated independently.
- Indication: A detected fault produces FLT and lights the FAULT indicator.
Channel Compare
- Dual input: C links IC3600SSVD1 with the companion-channel SCB signals.
- Decision: The alarm is assigned to the side whose SCB is more positive than C.
- Purpose: The comparison distinguishes the channel associated with the larger discrepancy.
