10. Stroke-end

10.1. Stroke-end at opening and closure

The stroke-end at opening and closure is automatic, electronic and cannot be
programmed. The actuator is stopped by the absorption of power encountered when
the window is completely open or completely closed.

10.2. Stroke adjustment where required

Strokes shorter than the stroke produced during manufacture can be created at will to
suit the protrusion length of the rod.
This operation should be performed on the bench using the appropriate equipment by
qualified technical personnel with the ability to perform each operation with maximum
diligence and safety.
Work phases are as follows:
1. Remove the four screws on the front head of the actuator.
2. Remove the body of the actuator and the rack from the rod.
3. Unscrew the two screws locking the two limit switch block pieces.
4. Move the rubber stopper and block to the required position.
5. Screw the two screws used for fixing the block into position back in again.
6. Reassemble everything onto the actuator rod.
7. Screw in the four screws on the front head and check the settings for the new track
run.

11. Checking for correct assembly

• Check that the frame has closed completely, even at the corners, and check there
are no obstacles caused by assembly in the wrong position.
• Make sure the actuator is aligned with the axis of the window at 90° to the window
itself, otherwise the rack will exert incorrect pressure on the rod and consume more
voltage.
• Check the lead is not too tight, as this could damage the actuator during rotation,
opening and closing of the window.
• Check all screws and nuts have been properly tightened.

12. Emergency manoeuvres, maintenance and cleaning

Should the window have to be opened manually in the event of no electricity,
mechanical failure, or for normal maintenance or cleaning of the external surface of the
window frame, the following instructions should be followed:
1. Unscrew the nut from the pin screw fixing the eyebolt head to the front shaft.
