Position of actuator bolt
The actuator bolt for moving the potentiometer lever can be
mounted permanently on the lever itself or on the valve stem.
Depending on the mounting method, when the valve moves the
actuator bolt performs either a circular or a linear movement
with reference to the center of rotation of the potentiometer
lever. Select the chosen bolt position in the HMI menu in order to
ensure optimum linearization. The default setting is as follows:
