1 Program the Travel

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY
INJURED or KILLED by a closing door.
Incorrect adjustment of door travel limits will interfere with proper operation of safety reversal system.
l
After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on
l
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.
NOTE: While programming, 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.
2. Press and hold the UP Button until the door is in the desired UP position.
3. Once the door is in the desired UP position press and release the Adjustment Button. The door operator
lights will flash twice and the DOWN Button will begin to flash.
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 door
operator lights will flash twice. Program the Travel is now complete. If the door operator 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 Setup
Once both the up and down positions have been manually set, the Safety Reversing Sensors will reconnect and
become operational. Then, the door operator will enter a force-sensing operation by automatically moving the door
open and close. The door operator will sound an audible alert before automatically opening and closing the door. The
door operator 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.
If you are unable to operate the door up and down, repeat the steps for Programming the Travel.
