Each record is marked with [Date] (year.month.day), [Time] (hour:minute:second.hundredth.thousandth),
[Grp] (group identifier), [Evt] (event identifier), and [Description]. The event record numbers [No] are
entered from the PU4 module from 0 to 9999. After 9999, the event-counter restarts with 0.
For a better understanding of the event-recorder entries, set the time and date on the PU4 with PowerSys
before starting operation. During power off, time and date are saved on the PU4 for about 96 hours. The
recorded event entries are non volatile.
