10.2.2.19 Description of parameter 49
49.FSTY - safety position
Use this parameter to move the actuator to a defined safety position when communication
fails. Three settings are available:
●
FSVL:
the actuator is controlled using the parameterized safety setpoint. This value also
becomes effective after a power failure.
● FSSP:
the actuator is controlled using the last effective setpoint.
● FSAC:
the exhaust air valve is opened. The single-acting actuator moves to the end position due
to its spring force.
The factory setting is "FSAC".
10.2.2.20 Description of parameter 50
50.FSTI - monitoring time to set the safety position
If communication fails, the positioner switches to the safety position after the set value
expires.
The factory setting is "0".
