Use input DIN 5 for signal OPEN / CLOSE:
Parameter: Signal DIN 5 M0122 = OPEN/CLOSE
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g. Coding DIN 6 M0128), the input is either High active or Low active. Default
setting is High active.
Option
This function requires one of the following equipments within the actuator:
Electronic control unit with MWG (Non-Intrusive version)
Potentiometer
Electronic position transmitter EWG/RWG
Further conditions for the positioner operation mode:
Positioner enabled and activated.
Operation mode Remote (selector switch = position Remote control).
The positioner records setpoint position E1 and actual position value E2 for
comparison. Depending on the detected deviation, the actuator motor then runs in
direction OPEN or CLOSE.
If the actuator is controlled via a setpoint (e.g. 0 – 20 mA), the status indication
S0003 on the display shows both the setpoint position E1 and the actual position
value E2.
If the status indication S0003 only shows the actual position value E2, OPEN
- CLOSE control is active: there is no setpoint control via the positioner. In this
case, you have to change-over to setpoint control first, refer to <Change-over
between OPEN - CLOSE control and setpoint control> chapter.
Required user level: Specialist (4) or higher.

Application functions M0178
Activation M0212
Positioner M0158
Default value: Function not active
Setting values:
Function <Positioner> deactivated.
Function <Positioner> activated.
Adaptive positioning may reduce the number of starts and compensate for the overrun
of the actuator.
Customer settings M0041
Positioner M0145
Adaptive behaviour M0147
Default value: Adaptive I
Setting values:
Adaptive behaviour switched off.
Adaptive behaviour for precise positioning (high positioning accuracy).
Due to the inertia of actuator and valve, the valve position changes only slightly after
switching off the actuator (overrun). The positioner determines the resulting error
