5.6 A5 EVENT RECORDER 5 ACTUAL VALUES
5
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.
EVENT01 is the most recent event and EVENT40 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 information can be cleared
using
S1 489 SETUP ÖØ CLEAR DATA ÖØ CLEAR EVENT RECORD setpoint. The event record will not update if a digital input
programmed as Test Input is shorted.
