5.6 A5 EVENT RECORDER
The 489 Event Recorder stores generator and system information each time an event occurs. The description of the event
is stored and a time and date stamp is also added to the record. This allows reconstruction of the sequence of events for
troubleshooting. Events include: all trips, any alarm optionally (except Service Alarm, and 489 Not Inserted Alarm, which
always records as events), loss of control power, application of control power, thermal resets, simulation, serial communica-
tion starts/stops and general input control functions optionally.
