Alarms & troubleshooting

MAINS_FAIL / AC_POWER_LOSS
Power distribution Amber LED solid, controller buzzer active
Mains utility grid failure, upstream transformer trip, or main AC breaker open
1. Verify battery discharge current and remaining backup runtime on monitor;\n2. Start standby generator (DG) and confirm transfer switch closure;\n3. Measure incoming 3-phase AC voltage and frequency stability;\n4. After grid recovery, verify rectifiers soft-start and initiate boost charging.
LLVD_TRIP / LOAD_SHEDDING
Controller screen displays LLVD alarm, DC load contactor opened
Prolonged blackout caused battery voltage to drop below threshold (44.0VDC default), shedding non-critical loads
1. Confirm priority telecommunication loads on BLVD branch remain powered;\n2. Deploy mobile emergency power generators to replenish battery plant;\n3. Upon grid restoration, observe DC bus rising past reset threshold (48.0VDC);\n4. Verify all load shedding contactors re-engage and resume service.
SPD_FAIL / SURGE_ARRESTOR
Surge arrestor inspection window turns Red from Green, alarm relay closed
Lightning induced transient surge or utility overvoltage caused MOV thermal breakdown and disconnection
1. Inspect visual disconnect indicator window on AC surge protector module;\n2. Verify upstream SPD backup fuse or miniature circuit breaker status;\n3. Open SPD circuit breaker and pull out damaged plug-in cartridge;\n4. Insert genuine replacement cartridge (20kA/40kA rating) and reset breaker.
