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.
The event recorder data may be inaccurate if 489 relay power-on time is less than
2 seconds.
The date and time stamping feature 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 communication starts/stops, and
general input control functions optionally.
