9.4 Description of parameters
9.4.2.14 Description of parameters 44
44.AFCT - Alarm function
This parameter can be used to determine the value at which going above or below a given
offset or angle will result in a message. The triggering of alarms (limits) is relative to the
MPOS scale. Alarms are signaled through the alarm module. In addition, alarms can also be
read out over the HART communicator (optional).
The direction of action of the binary outputs can be adjusted from "High active" to "Low
active" for the next system.
Note
If the extended diagnostic is activated using parameter "51.XDIAG" with setting "On2" or
"On3", then the alarms will not be output through the alarm module. Notification through
HART communication is possible at any time, however.
