Safety position
This parameter is used to move the actuator into a set safety position if
communication fails.
Three settings are possible
❑ FSVl
the actuator must continue to control with the parameterized safety set-
point
❑ FSSP
the actuator must continue to control with the last effective setpoint
❑ FSAC
Here this outlet air valve is opened and the single–action actuator
moves to its final position by spring power.
Monitoring time for setting the safety position
In the event of a failure of communication, the positioner moves to the
safety position after the set value has elapsed.
Safety setpoint
Specification for the safety position.
Station number
So that the devices on the bus can be addressed separately, a sepa-
rate station number must be set on each device.
