If the camshaft is positioned correctly, then the indicator on the camshaft disc coincides with
the position of the ball valve:

Use of locking plate as a lever

The valve shaft can be brought into the correct position with the help of the locking plate. If
pliers are used, they could damage the valve shaft.

Selecting the rotation angle (90° or 180°)

The factory setting for the ball valve rotation angle is

180°

. This rotation angle is determined

by the fixed control cam located on the shaft. In its end positions, this control cam actuates a
limit switch, thereby switching off the drive motor.
