SafePos off

The actuator remains in the position which cor-
responds to the set-point value last transferred
(default setting).

SafePos on

If there is a fault in the bus communication, the
behavior of the actuator depends on the acti-
vation of the

SAFEPOS auxiliary function.

SAFEPOS activated:
The actuator moves to the safety position which is specified in the

SAFEPOS auxiliary function.

SAFEPOS deactivated:
The actuator moves to the safety end position which it would

assume if the electrical and pneumatic auxiliary energy failed.
See Chapter “15. Safety end positions”.
