Assembly
• Only connect the drive with the power turned o󰀨.
• The limit switch only functions if the drive has been installed
properly in the winding shaft.
• Never adjust the end position to a mechanical stop.
• The length of the winding shaft is to be determined for each
individual installation depending on the drive head and motor
bearing used at the installation site.
Installation in prole tubes (see Figure)
• Push the drive with relevant adapter and limit switch crown
into the prole tube.
• Secure the drive in the motor bearing.
• Secure the counterpart support to prevent axial movement
(screw on the idler or rivet it on).
• Attach the blind to the winding shaft.
Do not drill holes in the area of the drive.
Installation in round tubes (see Figure)
• On the round tube, cut a slot in the end of the tube on the
drive side (width 4 mm, length 16 mm).
• Push the drive into the round tube so that the drive lug of
the limit switch crown engages in the slot.
• Screw or rivet the adapter onto the winding shaft.
• Secure the counterpart support to prevent axial movement
(screw on the idler or rivet it on).
• Attach the blind to the winding shaft.
Do not drill holes in the area of the drive.

Adjustment of end positions
Important: The limit switch setting screws for the upper end
position and lower end position are assigned depending on
the parallelism of the rotating limit switch crown with the run-
ning direction arrow (see Figure).
The basic factory setting when delivered is centrally set at 5
revolutions.
6 revolutions of one of the two limit switch setting screws
corresponds to 1 revolution of the winding shaft.
Turning the limit switch setting screw from negative to positive
causes the travel path of the blind to increase.
Upper end position
1. Let the drive (with no connection to the blind) run in the
DOWN/CLOSE direction until it switches o󰀨 automatically.
2. Attach the rolled-down blind to the shaft.
3. Push the UP button and keep this held down.
4. If the drive switches o󰀨 before it reaches the desired end
position, turn the limit switch setting screw towards positive
until the desired blind position has been reached.
5. If the drive does not switch o󰀨 automatically when the desi-
red end position has been reached, release the button. Run
the blind slightly in the other direction. Turn the correspon-
ding setting screw towards negative and approach the end
position again. Repeat this process until the desired end
position has been reached.
Lower end position
1. Push the DOWN/CLOSED button and keep this held down.
2. If the drive switches o󰀨 before it reaches the desired end
position, turn the limit switch setting screw towards positive
until the desired blind position has been reached.
3. If the drive does not switch o󰀨 automatically when the desi-
red end position has been reached, release the button. Run
the blind slightly in the other direction. Turn the correspon-
ding setting screw towards negative and approach the end
position again. Repeat this process until the desired end
position has been reached.
Checking the end positions
Allow the drive to run alternately in both directions until the
limit switch switches o󰀨. The electric cut-out must take place
before the blind has reached the end position of its mechani-
cal travel path.
If the blind is constantly operated as far as its end position,
there is a risk that the drive and/or blind will be damaged or
destroyed.
NOTE: The limit switch only functions if the drive has been in-
stalled properly in a winding shaft (prole tube or round tube).
