Adjustment

Introduction

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 2×4 laid flat) on floor.

To prevent damage to vehicles, be sure fully open door provides adequate clearance.

Your garage door opener is designed with electronic controls to make setup and adjustments easy. The adjustments allow you to program where the door will stop in the open (UP) and close (DOWN) position.
The electronic controls sense the amount of force required to open and close the door. The force is adjusted automatically when you program the travel. 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.
NOTE : If anything interferes with the door’s upward travel it will stop. If anything interferes with the door’s downward travel, it will reverse

Programming Buttons

The programming buttons are located on the side panel of the garage door opener and are used to program the travel. While programming, the UP and DOWN buttons can be used to move the door as needed.

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 2×4 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.

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.
Press and hold the UP Button until the door is in the desired UP position.
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.
Press and hold the DOWN button until the door is in the desired DOWN position.
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.

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 is completed successfully. The adjustment is complete.
If you hear one long beep after the door attempts to move, then the Automatic Force setup has not been completed successfully. Please start over at step 1 of Program the Travel

Test the Safety Reversal System

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 2×4 laid flat) on the floor

Automatic Garage Door Opener Safety & Maintenance Guide

Garage Door Opener Safety – An Automatic Decision

A garage door is the largest moving object in the home. An improperly adjusted garage door and opener can exert deadly force when the door closes – which could lead to entrapment of children or adults and subsequent injury or death. Proper installation, operation, maintenance, and testing of the garage door and automatic opener are necessary to provide a safe, trouble-free system. Careless operation or allowing children to play with or use garage door opener controls are also dangerous situations that can lead to tragic results. A few simple precautions can protect your family and friends from potential harm. Please review the safety and maintenance tips in this guide carefully and keep it for reference. Check the operation of your garage door and opener to ensure they function in a safe and trouble-free manner. Be sure to read all Important Safety Information found in your garage door opener’s manual as it provides more details and safety considerations than can be supplied with this guide.

Garage Door Openers are Not Toys
Discuss garage door and opener safety with your children. Explain the danger of being trapped under the door.

Stay away from a moving door.
Keep transmitters and remote controls out of reach of children. Do not let children play with or use transmitters or other remote control devices.
The wall-mounted push button should be out of reach of children, at least 5 feet from the nearest standing surface and away from all moving parts. Mount and use the button where you can clearly see the closing garage door.
Keep the door in sight until it completely closes when using the wall-mounted push button or transmitter

Routine Maintenance Can Prevent Tragedies

Make monthly inspections and testing of your garage door and opener system a part of your routine. Review your owner’s manual for both the door and door opener. If you don’t have the owner’s manuals, contact the manufacturer(s) and request a copy for your specific model(s). Look for the opener model number on the back of the power unit.
WARNING – Springs are under high tension. Only qualified individuals should adjust them.

Visually check the door and installation:

Starting with the door in the closed position, use the manual disconnect on the opener to disconnect the door.
Look for signs of wear or damage on hinges, rollers, springs, and door panels.
These parts may require periodic lubrication. Check the owner’s manual for suggested maintenance.
If any signs of damage are evident, contact a trained door systems technician for assistance.
Verify the photoeye height is no higher than 6″ from the garage floor.

Test the door for proper operation:

Open and close the door manually using handles or suitable gripping points.
The door should move freely and without difficulty.
The door should balance and stay partially open 3–4 feet above the floor.
If you detect any signs of improper operation, contact a trained door systems technician for assistance.

Test the opener safety features:

Reconnect the opener to the door using the manual disconnect and open the door.
Place a 2×4 board flat in the path of the door (1) and try to close it (2). The door should stop when it comes in contact with the 2×4 and then reverse direction.
Block the photoelectric sensor by waving an object in front of the sensor and attempting to close the door. The door should not close unless the wall-mounted push button is manually held during operation.
If the opener does not perform as described, contact a trained door systems technician for assistance.
