For reversing the running direction, the drive must be de-energized for at least 1 s.
Switch-off in closed position
Thanks to the integral load interruption, the drive switches off in closed position. Setting the
limit switch is therefore not required. When the end position is reached, the drive carries out a
reverse travel of approx. 1 mm. Thus relieving both gaskets and holding brackets.
Setting the travel
The factory setting of the travel is 400 mm; it can be changed via DIP switches at any time. The
DIP-switches lie detailed under the black screw cap on the upper side of the engine case. The
DIP switches 1 and 2 have to be set according to the following table.
In order to make a change effective, it is necessary to extend the chain a little bit and retract it
again.
After changing the travel, a test run should be carried out.
