ALARM CODES
Using a sophisticated self-diagnosis system, the UPS is able to check its own status for 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).
FAULT
FAULT alerts can be divided into three categories:
¾ Anomalies: these are “minor” problems which do not cause the lock of the UPS but reduce performance or
prevent certain functions from being used.
CODE DESCRIPTION
A06
Sensor1 temperature under 0°C
A08
Sensor2 temperature under 0°C
A54
Load percentage greater than the user threshold set
A61
Replace batteries
A62
Batteries missing or Battery Box missing or not connected
A63
Waiting for battery charging
¾ Alarms: these are more critical problems than anomalies because, if they persist, they could cause the UPS to
lock in a very short time.
