After each setting or changing of the end points, you must set the force limit.
For this purpose, three reference travels must be performed in each travel direction. If these reference travels have not yet been made, the drive must not yet respond to the hand-held transmitter.
Press the red key on the side of the drive to start the first of the three reference runs. The hand-held transmitter should not function until the drive illumination stops flashing during the run.
