5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Supply OK LED not lit | No input voltage | ✅ High | Measure AC voltage at input terminals | Confirm certified power feed meets 85-264 Vac |
| Redundant supply alarm | Single feed issue | ✅ High | Verify both input sources | Check dual circuit breakers and wiring |
| Module not recognized | Poor seating | ✅ Medium | Inspect physical installation | Power down and reseat firmly |
| Over temperature | Restricted airflow | ❌ Low | Check rack fans and ambient conditions | Improve ventilation in hazardous enclosure |
| Certification-related fault | Improper grounding | ✅ Medium | Verify grounding per NEPSI/ATEX | Follow hazardous area installation manual |
Send diagnostic logs, photos of LEDs, and installation details if the issue remains unresolved.
