LARM CODES
By using a sophisticated self-test system, the UPS can check and report on the display panel any problems
and/or failures that could occur during normal operation of the equipment. In case of a problem, the UPS
signals the event by posting on the display the code and type of alarm present (FAULT and/or LOCK).
FAULT
The FAULT type reports may be divided into three categories.
Failures: these are "minor" problems that do not result in the UPS stopping but they limit its
performance or prevent certain features being used.

Alarms: these problems are more critical than the failures because – if they continue – they could
cause the UPS to stop, even in a very short time frame.
