The microprocessor control unit operates in sequential impulse
logic. The door can be operated using the test button, the operating
button fitted to the front of the control unit, the remote control hand set
or other optional controls connected to the system. Push any of the
above buttons and the door will open. Push a button again and the door
will close. If a button is pressed whilst the door is moving it will stop and
pushing the button again will reverse the original direction.
The advanced electronics monitor the motor drive and limit switches and
turn off the motor run timer as soon the door reaches a fully open or a
fully closed position.There is no need to wait for the run time to expire

photoelectric safety sensor will not affect a recently closed door.
