5.3.1 Alarm list
The alarm list shows all alarms that are present in their order of occurrence. If an alarm is no longer pres-
ent, its entry is automatically removed from the alarm list. The alarm list is rebuilt after power on.
Each alarm represents an event. For this reason, the time at which an alarm occurs and disappears
again is recorded in the event list.
An alarm that is present is additionally shown in the status bar and by the red LED.
