7. The "Alarm" menu
This display shows an overview of the submenus of the "Alarm"
menu.
In this menu, it is possible to see existing alarms, to reset alarms
and to see the alarm log.
A system fault
or a monitored component can generate an alarm
or a warning
in addition to the fault indication via the alarm/
warning relay and the red indicator light on CU 362.
An alarm can cause a change of the operating mode, for
example from start to stop.
A warning is reported, but it does not cause the system to stop.
