Test The Safety Reversal System; Test The Safety Reversing Sensors - Craftsman CMXEOCG781 Owner's Manual

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.
If the door stops but does not reverse:
1. Review the installation instructions provided to insure all steps were
followed;
2. Repeat Program the Travel (see Adjustment Step 1);
3. Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems technician.
ADJUST
If the door stops and does not reverse on the obstruction, the down travel
l
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.
Repeat the test.
l
If the garage door opener continues to fail the safety reversal test, call a
l
trained door systems technician.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
Each adjustment of door arm length, limits, or force controls.
l
Any repair to or adjustment of the garage door (including springs and
l
hardware).
Any repair to or buckling of the garage floor.
l
Any repair to or adjustment of the opener.

ADJUSTMENT STEP 3

TEST THE SAFETY REVERSING SENSORS

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 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.
l
After ANY adjustments are made, the safety reversal system MUST be tested.
l
Door MUST reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid
flat) on the floor.
Without a properly installed safety reversing sensor, persons (particularly small
children) could be SERIOUSLY INJURED or KILLED by a closing garage door.
