ADJUSTMENT STEP 2
Test the Safety Reversal System
TEST
1. With the door fully open, place a 1-1/2 inch (3.8 cm) board (or
a 2x4 laid flat) on the floor, centered under the garage door.
2. Press the remote control push button to close the door. The
door MUST reverse when it makes contact with the board.
ADJUST
l
If the door stops and does not reverse on the obstruction, the
down travel needs to be increased (refer to Adjustment
Step 1).
NOTE:
On a sectional door, make sure adjustments
do not force the door arm beyond a straight up and down
position.
l
Repeat the test.
l
When the door reverses on the 1-1/2" (3.8 cm) board (or 2x4
laid flat), remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.
l
If the garage door opener continues to fail the safety reversal
test, call a trained door systems technician.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
l
Each adjustment of door arm length, limits, or force controls.
l
Any repair to or adjustment of the garage door (including
springs and hardware).
l
Any repair to or buckling of the garage floor.
l
Any repair to or adjustment of the opener.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
l
Safety reversal system MUST be tested every month.
l
After ANY adjustments are made, the safety reversal system
MUST be tested. Door MUST reverse on contact with 1-1/2"
(3.8 cm) high object (or 2x4 laid flat) on the floor.
1-1/2" (3.8 cm) board
(or a 2x4 laid flat)
ADJUSTMENT STEP 3
Test The Protector System
®
1. Press the remote control push button to open the door.
2. Place the opener carton in the path of the door.
3. 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 control if the
LED in either safety reversing sensor is off (alerting you to the
fact that the sensor is misaligned or obstructed). If the garage
door 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.
Without a properly installed safety reversing sensor, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
