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.
Unbalanced input voltages (three-phase input)
Load percentage greater than the user threshold set
Batteries missing or Battery Box missing or not connected
UPS work in Manual Bypass operation mode
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.
Dissipator over temperature
Capacitor bank undervoltage
Capacitor bank overvoltage
Unbalanced capacitor bank
Failed capacitor bank soft start
