Alarm 20:
When the bypass is connected during the start up, a bypass phase rotation error is
detected and the start up procedure is inhibited.
Alarm 21:
This alarm appears when in any phase, the rectifier input voltage phase to neutral
is out of the set margins (+15 %/–20 % by default) or the rectifier input frequency
is out of the set margins (±5 Hz by default). Then the rectifier is shut down.
Alarm 22:
This message appears when the protection circuit is activated to prevent overload
of the IGBT rectifier.
Alarm 23:
This message appears when an internal error in the digital signal processor (*) DSP
occurs in the rectifier module. The rectifier is shutdown immediately. The UPS will
make 3 attempts to restart, then the rectifier will be blocked.
Alarm 24:
When a mains phase rotation error is detected and under these conditions the
rectifier is tried to be turned ON, an input phase rotation alarm appears shutting
down the rectifier.
Alarm 25:
This message appears when the protection circuit for the avoidance of
DC inverter-IGBT overload is active.
Alarm 26:
This message appears when the inverter becomes overloaded (> 100%).
Alarm 27:
When an external shutdown signal is enabled, the inverter will shut down
appearing this message.
Alarm 28:
When the inverter is running and the maintenance bypass switch is turned ON
the inverter shuts down immediately.
Alarm 29:
This alarm appears when, in a parallel system, one UPS goes to battery mode.
The inverter will shut down.
