9 LIST OF ALARMS
There are three types of alarm resets:
— Auto: automatic, when the event causing the alarm stops, also the alarm disappears.
— Manual: manual, to restart normal operation manual acknowledgement is necessary.
— Semi-auto: semi-automatic, the alarm is automatic but if it is present more than “n” times, it then becomes manual. The interventions are decreased by one unit every hour.
Furthermore, there is a “timeout”, after which the alarm becomes manual, even if the maximum number of interventions is reached.
