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.
The highest event number is the most recent event, and lowest event number is the oldest event. Each new event bumps
the other event records down until the 40th event is reached. The 40th event record is lost when the next event occurs. This

input programmed as Test Input is shorted.
