During initialization, the 1441 cPos-X positioner automatically detects the control function of the
valve and is adjusted by default so that the valve is closed when the signal is 4 mA*.
The assignment can subsequently be changed using parameters. The close-tight function that is in-
tegrated as standard ensures that the valve is moved completely to the end position when the sig-
nal Open or Close valve is given.
* For double acting actuators, depends on the pneumatic actuator
