Installation & Operation Manual
6 - 5
arm is a combination of the loading state (idle, running, and so on) and
the alarm severity of the loading arm. From that icon the highest
severity among the active alarms associated with the loading arm can
be read.
6.4 Alarm Output Configuration
In the MSC-L two different alarm output bindings per loading arm can
be configured. These are:
The alarm-indication output can be set with
[Alarm indication]
I/O
binding entity.
The alarm-shutdown output can be set with
[Alarm shutdown]
I/O
binding entity.
The alarm shutdown output of a loading arm activates when the alarm
severity of that loading arm becomes critical. A critical severity is a
severity that is equal to either Pause & Display or Shutdown & Display.
The reverse is also possible. If the alarm severity of the loading arm
becomes non-critical then the alarm shutdown for that loading arm is
deactivated. The severity is non-critical when it is not critical, so it is
either None or Display.
The (de)activation of the alarm indication output is dependent on the
number of unacknowledged active alarms that affect the loading arm.
When the number changes from zero to a number larger than zero, the
alarm indication output is activated. When the number changes from a
number larger than zero to zero, then the alarm indication output is
deactivated.
