10.2 Setting for end position OPEN (white section)
.
Turn handwheel counter-clockwise until valve is open.
.
Turn handwheel approx. 1 turn in direction CLOSE and then half a turn in
direction OPEN.
.
Press down
and turn setting spindle D (figure E1) with screw driver (5
mm) in direction of arrow, thereby observe switch cam E. While a ratchet
is felt and heard, the switch cam E moves 90° every time. When switch
cam E is 90° from the switch, continue turning slowly.
When the switch cam E snaps and trips the switch, stop turning and
release setting spindle.
If you override the tripping point inadvertently (ratchet is heard after the
switch cam has snapped), continue turning the setting spindle in the same
direction and repeat the setting process.

Clean sealing faces at cover and housing; check whether O-ring is in good
condition. Apply a thin film of non-acidic grease to the sealing faces.
