33/86 MegaFlex 1000 to 1600 UPS User Manual / REV-A
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 “Data Protection” installed or with the monitoring system “iUPSGuard”.
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).
