6.3.1 Events (alarms and messages)
Each of the following listed events, alarm or message, can be displayed on the LCD screen, on a PC with
the software “GE Data Protection” installed or with the monitoring system “GE Power Diagnostic”.
Alarms and Messages are differently specified because the alarms are indicating an abnormal
functioning of the UPS (which are additionally signaled with the LED Alarm and acoustically with the
buzzer), while the messages indicate the various states of operation of the UPS (stored in the events list,
but not activating the LED alarm and the acoustical alarm).
