CAUTION
Risk of injury!
The device includes slot sensors with sharp edges.
• Adjust the metal tags using a screwdriver only!
2. Set the upper and lower switching points for binary feedback
as follows:
• Select the 'Manual Adjustment' operating mode and move
the final control element by hand into the lower switching
position.
• Using a screwdriver, adjust the metal tag of proximity
switch 1 (lower contact) on the axis until contact is made,
i. e., just before it is inserted in the proximity switch. The
slot sensor enters proximity switch 1 when the feedback
shaft is rotated clockwise (as viewed from the front).
• Move the final control element by hand into the upper
switching position.
• Using a screwdriver, adjust the metal tag of proximity
switch 2 (upper contact) on the axis until contact is made,
i. e., just before it is inserted in the proximity switch. The
slot sensor enters proximity switch 2 when the feedback
shaft is rotated counter-clockwise (as viewed from the
front).
3. Attach the housing cover and screw it onto the housing.
