Symptom / LED Pattern	Likely Cause (What it Means)	Recommended Corrective Action
Green “24 V” LED off	No / low 24 V DC (< 20 V) or reversed polarity	Check cabinet PSU, fuse & wiring polarity; restore 24 V then repower card.
Green “15 V” LED off (24 V OK)	On-board logic regulator failed	Measure +15 V at monitor point z22; if 0 V replace regulator or the card.
Yellow “Enable” LED dark though PLC drives > +10 V to z24	Enable line actually < +6 V (broken field wire / PLC output)	Trace/repair z24 wiring, restore proper voltage, reseat card to reset.
Red “Overload” LED lit	Solenoid current > 1.5 A (shorted coil / mis-wired valve)	Measure coil R, inspect cable for shorts, fit correct coil; LED clears automatically.
Command signal present but no valve response	Set-minimum or Gain* pots fully CCW*	Turn pots CW until monitor jack MP1 shows ≥ ±0.5 V; re-test valve motion.
Ramp pots have no effect / valve jerks	Ramp-bypass link b12-b20 closed	Remove jumper or wire it via remote switch to re-enable ramp generator.
LVDT-fail LED on (feedback card fitted)	Feedback sensor open / out of range	Verify ±15 V sensor supply, inspect 6-pin LVDT cable; repair & re-zero PID.
PID integrator saturated (MP6 pegged)	I-gain too high or sensor polarity reversed	Reduce I-gain pot, swap sensor leads, power-cycle to clear integrator.
Card resets when supply falls below ≈ 19 V	Undersized PSU or long cable drop tripping low-V protection	Use ≥ 40 W PSU, larger conductors to cut voltage drop.
All LEDs extinguish at high ambient (> 50 °C)	Internal over-temperature shutdown	Improve cabinet ventilation, keep card below 50 °C, allow cool-down before restart.
