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
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.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
• Each adjustment of limits.
• Any repair to or adjustment of the door (including springs and hardware).
• Any repair to or buckling of the floor.
• Any repair to or adjustment of the garage door opener.
Test the Safety Reversal System
Test the Protector System
1. Open the door. Place an obstruction in the path of the door.
2. Press the remote control push button to close the door. The door will not
move more than an inch (2.5 cm), and the garage door opener lights will
flash 10 times.
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 inches [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.
• 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.
Without a properly installed
safety reversing sensor, persons
(particularly small children) could
be SERIOUSLY INJURED or
KILLED by a closing garage door.
