the Safety Obstruction Force. Excessive force

PROPERTY DAMAGE
WARNING!
FOR ADDITIONAL ENTRAPMENT
protection we STRONGLY recommend the fi tting
of a Photo Electric (PE) Beam. In most countries PE
Beams are mandatory on all garage doors fi tted
with automatic openers. For a small additional
outlay Automatic Technology recommends
that Photo Electric Beams be installed with the
automatic opener ensuring additional safety and
peace of mind.
WARNING:
Photo electric beams must be
installed if the closing force at the bottom edge of
the door exceeds 400N (40kg force)
Step 16.1 - Testing Close Cycle
Press the OPERATE button to open the door
(Fig.
33).
Place a piece of timber approximately 40mm high
on the fl oor directly under the door
(Fig. 34).
Press the OPERATE button to close door. The door
should strike the object and start to re-open.
Step 16.2 - Testing Open Cycle
Press the OPERATE button to close the door
(Fig.
33).
Press again to open the door. When the door
reaches the half open point, grab the bottom rail of
the door fi rmly and the door should stop.
If the door does not reverse readily when closing,
or stop when opening, the force may be excessive
and need adjusting, refer below.
DANGER!
If the door fails these tests, put the
opener into manual mode, only operate the door
by hand and call for service.
