Emptying the alarm buffer: Alarm history
The alarm history traces up to 56 alarms.
The alarm history only takes alarms that have been removed from the alarm buffer. If the
alarm buffer is completely filled - and an additional alarm occurs - then the inverter shifts all
alarms that have been removed from the alarm buffer into the alarm history. In the alarm
history, alarms are also sorted according to the "alarm time received", however, when
compared to the alarm buffer, in the inverse sequence:
● The youngest alarm is in index 8
● The second youngest alarm is in index 9
● etc.
Figure 9-4
Any alarms that have not been removed remain in the alarm buffer. The inverter sorts the
alarms and closes gaps between the alarms.
If the alarm history is filled up to index 63, each time a new alarm is accepted in the alarm
history, the oldest alarm is deleted.
