ADJUSTMENT
OF DOOR MOVEMENTS
Pulse disk
A pulse disk fitted to the drive shaft is used to determine the door closed
position. This is achieved by the pulse counter calculating a series of holes
aroung the circumference of the disk, one of which is open. When the perimeter
sensor locates the edge of the notch the door operator stops the door.
Pulse counter
The counter has three sensors. Two count
the pulses and the disk direction, the
other senses the perimeter of the disk.
