Alarm Status - GE 489 Instruction Manual

5 ACTUAL VALUES
Immediately prior to issuing a trip, the 489 takes a snapshot of generator parameters and stores them as pre-trip values;
this allows for troubleshooting after the trip occurs. The cause of last trip message is updated with the current trip and the
screen defaults to that message. All trip features are automatically logged as date and time stamped events as they occur.
This information can be cleared using the
trip is "No Trip To Date", the subsequent pretrip messages will not appear. Last Trip Data will not update if a digital input
programmed as Test Input is shorted.
