4* Pin position
[No], 17, 25, 35, 50, 70,
100,200,300mm,90°
with rotary actuators, ESC
If you select a pin position
in Code 4 that is too small,
the positioner switches to
SAFE mode for reasons of
safety.
Follower pin must be mounted in the proper position depending on
thevalvetravel/openingangle.
Pin position must be entered for nominal (NOM) or substitute (SUb)
initialization.

90° 90.0 24.0 to 100.0
5* Nominal range
mm or angle °, ESC
Nominal valve travel or opening angle must be entered for nominal
(NOM) or substitute (SUb) initialization.
The possible adjustment range depends on the pin position from the
tableforCode4.

Automatic adaptation:
AIR TO
OPEN:
On completing initialization, the direction of action
remainsincreasing/increasing(ää). A globe valve opens
as the set point increases.
AIR TO
CLOSE:
On completing initialization, the direction of action
changestoincreasing/decreasing(äæ). A globe valve
closes as the set point increases.
