NOTE
If you have activated the extended diagnostics (parameter 51.XDIAG)
with On2 or On3, the alarms cannot be output via the alarm unit.
However , the message is possible via HART communication at any
time.
Response threshold alarm 1
and
Response threshold alarm 2
The alarm thresholds are related to the mechanical path (MPOS-scale).
Function of the fault message output
The fault message output serves as a group message for following
faults:
S Control error (e.g. by actuator fault, valve fault, compressed air fail-
ure) with the parameters “48.
TIM” and “49. LIM”
S Positioner not in automatic mode
S Digital input activated (see parameter “42.BIN1” and “43.BIN2”)
S Exceeding of a limit value (e.g. way integral or valve seat, see pa-
rameter 50 to 54)
It also responds at:
S Power failure
S Processor fault
The direction of action of the digital outputs can be adapted from high
active to low active sequence systems.
