Adjustments
1 - Program the Travel
Without a properly installed safety reversal system, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.
•
Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal
system.
•
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 floor.
Note: While programming the travel, the UP and DOWN buttons can be used to move the door as needed.
During the Automatic Force Setup, the door will automatically open and close.
1 Press and hold the
Adjustment Button
until the UP Button
begins to flash
and/or a beep is
heard. The Safety
Reversing Sensors
will be disconnected during the Program the Travel
process.
3 Once the door is in
the desired UP position
press and release the
Adjustment Button.
The garage door
opener lights will flash
twice and the DOWN
Button will begin to flash.
2 Press
and
hold
the UP
Button
until
the door is in the desired UP position.
4 Press
and
hold the
DOWN
button
until the
door is in the desired DOWN position.
5 Once the door is in
the desired DOWN
position press and
release the Adjustment
Button. The garage
door opener lights will
flash twice. Program
the Travel is now complete. If the garage door
opener lights flash 5 times, then programming has
timed out and the Travel Limits have not been set.
Please restart the Program the Travel process.
2 - Automatic Force Set Up
Once both the up and down positions have been manually set, the Safety Reversing Sensors will reconnect and
become operational. Then, the opener will enter a force-sensing operation by automatically moving the door
open and close. The garage door opener will sound an audible and visual alert before automatically opening
and closing the door. The garage door opener will beep three times, confirming that the Automatic Force Setup
completed successfully. Adjustment is complete.
If you hear one long beep after the door attempts to move, then the Automatic Force Set Up has not completed
successfully. Please start over at step 1 of Program the Travel.
NOTE: If the travel/force setup process is not completed successfully any attempt to activate the opener from a
remote/keyless entry or wall control will not work and the opener will flash the work lights 2 times.
