Safety Obstruction Force Test
WARNING!
Take care when testing or adjusting
the Safety Obstruction Force. Excessive force
may cause SERIOUS PERSONAL INJURY and/or
PROPERTY DAMAGE
WARNING!
FOR ADDITIONAL ENTRAPMENT
protection we STRONGLY recommend the
fi tting of a Photo Electric (P.E.) Beam. In most
countries P.E. 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 (40kgf)
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.
