oldest “last” event occurrence is removed from the log, and the new category takes its place. Since 50
event records with up to 99 occurrences each are retained in memory, a history of nearly 5,000 specific
events are retained in the DGC-2020. Detailed occurrence information is retained for the most recent 30
occurrences of each event record, and there are 50 event records; thus the time, date, and engine hours
details for up to 1,500 specific event occurrences are retained in the event log.

® can be used to view and download the event log. The event log may also be viewed
through the front panel HMI by navigating to Metering, Alarms-Status, Event Log. Use the Up/Down keys
to highlight an event and press the Right key to view the summary of that event record. The summary
contains the description of the event, date, time, and engine hours of the first occurrence of the event,
along with date, time, and engine hours of the most recent occurrence of the event. To view details of
specific event occurrences, press the Down key until DETAILS is highlighted, and then, press the Right
key. The occurrence number can be changed by pressing the Edit key, Up/Down keys to select #, and
pressing the Edit key again to exit. Table 3-7 lists all possible event strings (as shown in the event log).
