Assembling the limit buffer and the limit switch:
A limit buffer and a forced door contact are mandatory in the ‘Closed’ position if the door drive is to function
in a trouble-free manner. These must be set in such a way that firstly the door is fully closed and has
struck against the limit buffer; secondly, the forced door contact must make contact about 2 – 3 mm in front
of the buffer limit position.
The buffer is struck by the cheek on the door panel pusher door.
