Alarm 30:
This message appears when a parallel system has a UPS shutdown due to high
voltage.
Alarm 31:
When an over temperature is detected by the PFC or inverter temperature
sensors, after 1 minute time the inverter will be turned off automatically.
If over temperature condition remains after another 1 minute with the rectifier
working, rectifier is also blocked (alarm 60).
Alarm 32:
When the rectifier is overloaded, depending on the level of this overload, the
inverter will be shut down after some time according to the rectifier overload
curve and this alarm will appear. If this overload is still present with the inverter
switched off, the rectifier will be blocked after 30 seconds and blocking alarm 61
will appear.
Alarm 33:
This message appears when an internal error in the digital signal processor (*) DSP
in the AC rectifier module occurs. The inverter will shut down immediately. Four
attempts will be made to restart the UPS, then the inverter will be blocked.
Alarm 34:
This alarm appears when an output short-circuit is detected limiting the output
RMS current up to the set value (150 % of nominal current by default). The
short-circuit is detected when the output voltage phase to neutral is lower than
8 % of nominal voltage. The system will retry twice to restart.
Alarm 35:
With the inverter is running, if there’s a bypass phase rotation error, the inverter
will shut down.
Alarm 36:
This alarm appears when there is a (*) DSP Internal Error in the UPS module,
shutting down the UPS immediately. There will be 2 more retries before the UPS
blocking.
Alarm 37:
This alarm describes that on battery mode, the battery bank reaches the
10.5 V/battery pack This is the end of backup time, shutting down the UPS.
