8 Alarm and warnings
8.1 Alarms handling
When MC100 is in Alarm state, the only possible action is to reset the alarm. Only applies if the alarm
causes are removed, otherwise the alarm will re-appear at the next attempt.
Alarms are cleared one-by-one, starting top down – meaning lowest number first.
