Blockage

The blocking protection prevents the valve from seizing up. If the actuator stem is in the
closed position (0 %), it is extended slightly and then moved back to the closed position 24
hours after it last moved.
Movement of the actuator stem caused by the activated blocking protection is indicated by
the yellow LED:

Travel

The Actuator travel parameter determines in % how far the actuator stem can move at the
maximum. The travel determined during initialization acts as the reference.

Travel adjustment
Travel adjustment can be made to be absolute or relative. The way the travel adjustment is
made affects the control behavior.
− Absolute travel adjustment:
The absolute travel adjustment causes the actuator stem to move to the travel position de-
termined by the input signal. To achieve this, an automatic zero calibration is performed
after every start-up to obtain a reference value for the zero point. The position feedback
indicates the position of the actuator stem.
