Change endpoints
Note
If the motor travels too far up or down (does not stop when reaching the roller shutter box or the lower end point), the adjus-
ting screw responsible for this direction of travel must be turned in the "-" direction to shorten the travel distance.
To do this, first move the roller shutter to a "middle position" (roller shutter approx. half open).
Drehen Sie dann einige (5–6) Umdrehungen die entsprechende Einstellschraube in Richtung "-" und prüfen Sie erneut, ob der Motor
nun früher stoppt.
If necessary, start from the beginning.
In the factory, approx. 3-5 full shaft revolutions are set as limit switch range between OPEN and CLOSED.
If the motor does not stop in time, one of the adjustment screws may have been turned in the wrong direction too often.
Then unhook the shutter again and let the motor in the shaft run in the DOWN direction until it switches off automatically.
Once this is done, you can determine if you are using the correct adjustment screw for the appropriate direction of rotation by tur-
ning one of the adjustment screws in the "+" direction.
Make sure that the motor is still controlled by the control unit (press the DOWN key again).
ATTENTION!
Do not perform a "test run on the table", as this will not turn the race adapter on the motor head. The motor then does not
switch off and runs "endlessly"! This very quickly leads to overheating and shutdown of the motor by the built-in thermocou-
ple.
It is also not advisable to turn the adjusting screws before installing the motor in the shaft, as this usually leads to an uncont-
rolled adjustment of the end positions set at the factory.
