Fig. 18:
Actual process value for process controller (optional)
Terminals 15 to 17 serve to connect the parameterisable actual process value via
4-20 mA or 0/2-10 V signals supplied by the process sensor, if the optional process
controller in the actuator is used.
NOTE
The binary inputs described below take priority over the setpoint supplied: If the
actuator parameters are set for closed-loop control, the actuator will not follow the
setpoint supplied as long as binary signals are received. Only after the signal has
been removed will the actuator return to the position stipulated by the setpoint.

Fig. 19:
Galvanically isolated binary inputs
The binary Open/Close signals are connected to terminals 9 to 11. These inputs are
rated for 24 V AC/DC as standard. (

Section 9.3.3, Page 34) The actuator is
operated in open-loop control mode in this configuration.

Continuous actual-position feedback
Terminals 4 to 6 can be used for transmitting the parameterisable actual-position
value as a 4-20 mA or 0/2-10 V signal.
