Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
• Safety reversal system MUST be tested every month.
• If one control (force or travel limits) is adjusted, the other
control may also need adjustment.
• After ANY adjustments are made, the safety reversal system
MUST be tested. Door MUST reverse on contact with 1-1/2"
high (3.8 cm) object (or 2x4 laid flat) on the floor.

ADJUSTMENT STEP 3
Test the Safety Reversal System
TEST
•
With the door fully open, place a 1-1/2
"
(
3.8 cm
)
board
(
or a 2
x
4 laid flat
)
on the floor, centered under the
garage door.
•
Operate the door in the down direction. The door
must
reverse on striking the obstruction.
ADJUST
•
If the door stops on the obstruction, it is not traveling far
enough in the down direction. Increase the DOWN limit
by turning the DOWN limit adjustment screw
counterclockwise 1/4 turn.
NOTE:
On a sectional door, make sure limit adjustments
do not force the door arm beyond a straight up and
down position. See the illustration on page 21.
•
Repeat the test.
•
When the door reverses on the 1-1/2
"
(
3.8 cm
)
board,
remove the obstruction and run the opener through 3 or
4 complete travel cycles to test adjustment.
•
If the unit continues to fail the Safety Reverse Test, call
for a trained door systems technician.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
•
Each adjustment of door arm length, limits, or force
controls.
•
Any repair to or adjustment of the garage door
(
including springs and hardware
)
.
•
Any repair to or buckling of the garage floor.
•
Any repair to or adjustment of the opener.
ADJUSTMENT STEP 4
Test The Protector System
®
•
Press the remote control push button to open the door.
•
Place the opener carton in the path of the door.
•
Press the remote control push button to close the door.
The door will not move more than an inch
(
2.5 cm
)
, and
the opener lights will flash.
The garage door opener will not close from a remote if the
indicator light in either sensor is off
(
alerting you to the fact
that the sensor is misaligned or obstructed
)
.
If the opener closes the door when the safety
reversing sensor is obstructed (and the sensors are
no more than 6" (15 cm) above the floor), call for a
trained door systems technician.
