The fail-safe history memory stores up to 300 events (alarms, tests) with infor-
mation about alarms and acknowledgements and the time the event hap-
pened. If the history memory is full, the oldest entry will be deleted in the 
event of an alarm to create 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 38.
