Alarms & troubleshooting

AC_IN_FAIL / MAINS_LOST

Input Amber / Alarm Red solid

Utility grid failure, AC breaker tripped, or line voltage out of range

1. Measure incoming AC voltage with a multimeter; 2. Check input circuit breaker and upstream distribution; 3. System automatically soft-starts upon power restoration.

DC_OV_SHUTDOWN / LOCKOUT

Alarm Red solid, module output locked out

DC bus overvoltage or internal feedback sensor fault

1. Measure actual DC bus terminal voltage; 2. Cycle AC supply breaker to discharge capacitors and reboot; 3. Replace power module if fault recurs persistently.

FAN_FAIL / OVER_TEMP

Temp Yellow solid, fan halted or derated

Air intake dust blockage or fan bearing obstruction

1. Clean dust accumulation from intake grilles and filters; 2. Verify ambient room air conditioning is operational; 3. Replace cooling fan if rotation remains stalled.
