To test the Opener Reversing Feature at floor level, place a
solid object 100 mm thick on the ground so that the centre of
the door will contact it. Close the Door. If the Down force
Adjustments are Correct, the door will reverse within one and
a half (1-1/2) seconds of contacting the object and travel to the
Full Open Position. Light will also start flashing and continue to
flash for 30 seconds. If this does not occur, re-check Limit
Adjustments Page 15 and Force/Sensitivity Adjustments Page

Testing the Photo Eye System

Start the door down and then place an obstacle approximately
200 mm high by 300 mm wide in the path of the beam. The
Red Pilot Light on the Photo eye system should go off. The
door should stop for 1-1/2 seconds and reverse to the full
open position. The Opener light will also begin flashing and
continue to flash for 30 seconds. IF the door is moving up and
the beam is broken, the door will continue up to full open.
With the door fully open and at rest, place the obstacle in the
path of the beam once again. Activate the Wall Push Button,
The Opener will revert to and remain in the safety. Push And
Hold Operation for close travel. See Page 13.
