8. Troubleshooting
All OUT LEDs OFF: Check backplane, module seating, or ACTIVE LED
ACTIVE OFF: Module not recognized; reseat or check backplane
OUT LED ON but load not energized: Check external fuse, field wiring, or load
Erratic Operation: Poor grounding, noise, or overvoltage
Coating Note: Do not apply additional conformal coating; factory coating is sufficient
