At least one of the following modules is fitted
• Alarm module
• Slot initiator alarm module (SIA module)
• Mechanical limit switch module
Normal direction of action
•
nA
•
nAb
•
The fault message in the form of monitoring of control deviation
over time can also be triggered due to the following events:
• Power failure
• Processor fault
• Actuator fault
• Valve fault
• Compressed air failure
• Threshold 3 message of extended diagnostics.
See parameter '52.XDIAG' Activating for extended diagnostics
(Page 174).
The fault message cannot be switched off, but it can be sup-
pressed (factory setting) when you exit 'Automatic' mode. Set the
' FCT' parameter to ' nA' to also generate a fault message here.
You also have an option to "or" the fault message with the status
of the binary inputs. To do this, first set the '42.BIN1' / '43.BIN2'
Function binary input (Page 167) parameter to 'on' or '-on'. Subse-
quently set the ' FCT' parameter to ' nAb'.
Select the '- ' setting if you want the fault message to be output
with inverted direction of action.

The '48. TIM' parameter is used to set the time in seconds within
which the positioner must have reached the regulated condition.
The corresponding response threshold is specified in the '49. LIM'
parameter.
When the configured time is exceeded, the fault message output is
set.
