Alarm Codes - Riello 5KVA Installation And Use Manual

ALARM CODES

Using a sophisticated self check system, the UPS can verify and indicate on the display panel any faults
and/or malfunctions that may occur during the normal operation of the device. In the event of a problem, the
UPS indicates this by displaying the code and the type of alarm (FAULT and/or LOCK).
FAULT
FAULT signals can be subdivided into three categories.
1. Faults: these are "minor" problems that do not stop the UPS but reduce performance or prevent the
use of some of its functions.

2. Alarms: these are more critical problems than faults since if they persist, even for a very short time,
they may cause the UPS to stop.
