Auxiliary functions
24.2.12.1. Behavior of the actuator when safety position deactivated or
activated
Selection
SafePos off
– The actuator remains in the position which corresponds to the set-point value last
transferred (default setting).
Selection
SafePos on
– Approaching the safety position activated:
In the event of a signal fault detection, the behavior of the actuator depends on the activation of the
SAFEPOS
auxiliary function. See Chapter “24.2.11. SAFEPOS – Input the safety position”.
•
SAFEPOS
activated:
In the event of a signal fault detection the actuator moves to the position which
is specified in the
SAFEPOS
auxiliary function.
•
SAFEPOS
not activated:
The actuator moves to the safety end position which it would assume if the
electrical and pneumatic auxiliary power failed.
See Chapter “11.8. Safety end positions after failure of the electrical or pneu-
matic auxiliary power”.
The activation for approaching the safety position (selection
SafePos on)
is possible only when signal fault
detection has been activated (
ERROR on)
.
