6.10. WARNING AND FAULT INDICATIONS

The UPS recognises and draws attention to a number of events occurring during operation. These
events are divided into Warning and Fault indications. Whether the message is a warning or fault
can be determined from the number which appears in the Warning/Fault Diagnosis page of the dis-
play, and the buzzer signals.
Buzzer
The buzzer has two different patterns, which indicate the tyre of warning active.
• Pattern 1: long intervals - This event is less serious. It is not essential that the
cause be rectified immediately, unless otherwise specified in table "Warning indica-
tors".
• Pattern 2: short intervals - This is a serious event. The cause should be rectified
straight away to avoid a fault condition.
The buzzer is silenced automatically as soon as the cause of the event is rectified. It can
also be silenced manually by pressing the button TEST/RESET.

Warning indicators

If a warning indication appears, the UPS continues to operate. The yellow LED ALARM il-
luminates on the control panel. A number between 1 and 31 appears in the display indicat-
ing the type of warning.
