THE FOLLOWING
STEPS, IruSURC NOTHING IS IN THE
PATH OF DOOR BEFORE PROCEEDING.
NOTE: This operator is equipped with a thermal protector in
the motor circuit. If during the following steps the unit shuts
off and will not restart, wait 5-10 minutes for the motor to
cool down, then continue adjustment.
C. Push the transmitter button once. Keep the door pathway
clear of obstructions. The door should begin to close and
stop before reaching the floor. If it does not, refer to the
radio coding instructions (page 17) of this manual then
return to this section.
D. If the door begins to close then reverses and opens with
the lights on the opener blinking, either the beam sensor is
not properly connected and aligned (page 18) or the open
and close force adjustments must be increased.
E. If a force is selected which is lower than what is required
to move your door, the opener will reverse while closing
or stop while opening with the lights flashing.
F. If the door is closing and an object passes between the
sending unit and receiving unit of the beam sensor, the
door will reverse and open with the opener lights blinking.

OBSTRUCTION TESTING
A. Once the door can be cycled between the "factory set"
open and close positions without the system either stop-
ping or reversing with the opener lights blinking, activate
the door in the closed direction. While it is closing extend
your hands under the bottom edge of the door and try to
stop it. (The use of gloves is suggested.) Do not stand in
pathway of door or block beam sensor. The door should
reverse off of your hands and begin to open with minimum
force. If it does not reverse, or if the force is excessive,
decrease the close force until a lower level is selected.
Reference Fig. 47.
B. Once the close force is properly adjusted, activate the door
to open and try to stop it with your hands. Do not put fin-
gers between door sections. The door should stop (not
reverse) with minimum force otherwise the open force
must be decreased until a lower force is selected.
GLOSE TRAVEL ADJUSTMENT
lSmall Black Knobl
A. Push the transmitter button until the door closes and automat-
ically stops before reaching the floor. Locate the small black
close travel adjustment knob on the bottom of the porver unit.
See Fig 46.
B. Slowly turn this knob in the direction of the arrow (more
close travel) until the door moves. The door should "inch" its
way closed. Repeat inching the door closed until it reaches
the floor. Continue to turn the knob until the door is secure
against the floor with the tube slightly bowed.
C. If the door reverses off of the floor and opens turn the knob
slightly (ll4 turn at a rime) in the opposite direction of the
arrow and cycle the door again until the door is securely
closed without reversins off ofthe floor.
