The limit switching records the travel.When reaching the preset position (end
position/intermediate position), the switches are operated. For limit seating, the
signals of the end position switches are used for end position tripping.
We recommend switching off the actuator in the end position using the end
position switches to increase the lifetime.
The limit switching is located below the hood.
1. Turn valve via handwheel to the desired end position.
2. Open eccentric disc using a spanner (width across flats 10).

3. Adjust the cam using a screwdriver to cause switch tripping. Set the switching
point by turning the switch in the direction of the arrow of the <Limit switching>
figure.
