Description
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.

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.
Indicates maximum travel/angle reached during initialization after
initialization has been successfully completed.

NOM Nominal range
MAN Manual setting
SUb Emergency mode

MAX: Travel/angle of the closure member from the CLOSED
position to the opposite stop in the actuator.
NOM: Travel/angle of the closure member measured from the
CLOSED position to the indicated OPEN position.
MAN: Manually selected range
SUb:
Substitute calibration (without initialization)

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.
