History
The history memory stores up to 300 events (alarms, tests) with information about
alarms and acknowledgements and the time the event happened. If the history memo-
ry is full, the oldest entry will be deleted in the event of an alarm to make space for the
new entry (FIFO principle).
For details about erasing the entire history memory manually, refer to Chapter 5.4.4
"System" on Page 46.
