MGE UPS Systems UPS User Manual

This section describes the captured alarms and events,  including how to acknowledge and clear the alarm history
log. 

The alarm and event system gives the User a visual source for alarms and events that occur within each system.  

An alarm is a warning that a fault or major status change condition has occurred. 

An event is an indication of a status change condition resulting from an alarm.

There are two GCC screens to handle the alarm systems:

◗
