LARM 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 (FAULT and/or LOCK).
F
AULT

Anomalies:
these are “minor” problems which do not cause the lock of the
UPS but reduce performance or
prevent certain functions from being used.
