Alarms & troubleshooting

AC_MAINS_FAIL
Controller Major/Critical LED solid RED; Rectifier AC power LED OFF, Protection LED solid YELLOW
Utility grid blackout, AC input circuit breaker tripped, or AC voltage dropped below 85VAC cutoff limit; system operating on battery reserve.
Measure incoming AC phase voltages with a true-RMS multimeter; verify upstream ATS switch and surge protection circuit breakers; start standby diesel generator if grid outage exceeds site autonomy backup window.
DC_VOLT_LOW
Controller Critical LED flashing RED, audible buzzer active
DC bus voltage has dropped below configured undervoltage alarm threshold (typically 45.0V), indicating advanced battery discharge approaching the LLVD/BLVD cutoff points.
Immediately verify rectifier operation status; ensure modules are not in manual shutdown or severe current limitation mode; deploy mobile emergency DC/AC generator before BLVD disconnect occurs.
RECT_COMM_FAIL
Controller Major LED solid YELLOW; corresponding rectifier alarm LED flashing YELLOW
Internal CAN bus communication lost between supervisory controller and the specified rectifier slot due to loose backplane seating, broken termination resistor, or transceiver failure.
Firmly reseat the affected rectifier and verify locking latch engagement; inspect CAN cabling and terminal ribbons on the subrack backplane; execute 'Refresh/Auto-detect Rectifiers' in controller; swap module to isolate slot vs module fault.
RECT_OVER_TEMP
Rectifier Protection LED solid YELLOW, internal fan spinning at maximum RPM; controller posts WARNING status
Internal heat sink temperature has exceeded safety threshold (>75°C derating, >85°C protective shutdown), commonly caused by air filter clogging, blocked exhaust airflow, fan degradation, or room HVAC failure.
Clean or replace subrack/cabinet intake dust filters; verify that no cables or obstacles obstruct the front-to-back ventilation path; inspect rectifier fan blades for rotational clearance; ensure site ambient room temperature is restored to nominal levels.
LOAD_FUSE_BLOWN
Distribution panel circuit trip LED solid RED, controller triggers MAJOR alarm
A DC distribution fuse has blown or an MCB breaker has tripped due to field overload, branch short-circuit, or damaged auxiliary alarm sensor contacts.
Isolate the affected branch circuit; verify load wiring for low-resistance short circuits or negative-to-chassis faults using a digital multimeter; resolve downstream equipment fault before replacing with an identical rated fuse or resetting breaker; clear the alarm in the controller.
