4.5 Alarm codes
Using a sophisticated self-diagnosis system, the UPS is able to check its own status and any anomalies and/or faults
which may occur during normal operation and display them on the display panel. If there is a problem, the UPS signals
the event by showing the code and the type of active alarm on the display.
ALARMS
“Minor” problems which reduce performance or prevent certain functions from being used.
CODE DESCRIPTION
Unbalanced input voltages (three-phase input)
Load percentage greater than the user threshold set
A60D
Batteries missing or Battery Box missing or not connected
Low battery
FAULTS
Faults are normally preceded by an alarm signal and their scale leads to the power-off of the inverter and the load being
powered by the bypass line.
CODE DESCRIPTION
Dissipator over temperature
Capacitor bank undervoltage
Capacitor bank overvoltage
Unbalanced capacitor bank
Failed capacitor bank soft start
Failed inverter soft start
