5.1 Alarm and Event System
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:
◗ Alarm/Event Present
◗ Alarm/Event History
The alarm file capacity is 120 days First In - First Out (FIFO) stored in non-volatile memory.
