5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No output power | Input supply lost | High | Measure voltage at input terminals | Confirm upstream power source |
| Individual channels dead | Blown fuse or connection fault | High | Test continuity across fuses and terminals | Replace fuses and inspect wiring |
| Overheating | Overload or poor contact | Medium | Check current draw per channel | Reduce load and tighten connections |
| Voltage drop across board | High resistance joints | Medium | Measure voltage drop under load | Clean or replace affected terminals |
| Intermittent power | Loose mounting | Low | Inspect physical installation | Secure board and connections |
Contact support with voltage measurements and photos if the board does not perform after basic verification.
6. Frequently Asked Questions (FAQ)
Is the ALSTOM MK20 hot-swappable? No. Isolate and de-energize the system before any work on the distribution board to prevent arc flash or equipment damage.
What condition is this board? New Original / New Surplus. It carries full traceability from OEM stock.
Will this match my existing MK20 installation? It serves as a direct replacement for compatible variants. Confirm the specific suffix (such as C1L) and power ratings.
What warranty is provided? 1-year warranty on workmanship and function. It does not cover field installation damage or overload conditions.
What preparation reduces replacement errors? Photograph all wiring terminations, fuse positions, and labeling on the old board. Replicate the layout exactly on the new unit.
Do you supply test or inspection data? Yes. Visual and basic continuity checks are performed. Additional documentation is available on request.
What is the most common issue seen during swaps? Loose or incorrect terminal connections leading to voltage drop. Torque all screws to spec and verify polarity before re-energizing.
