The Protector System® (Safety Reversing Sensors)

Be sure power is NOT connected to the garage door opener BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from closing garage door:

Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be disabled.
Install the safety reversing sensor so beam is NO HIGHER than 6″ (15 cm) above garage floor.

The door will not close if the sensors have not been installed and aligned correctly.
When the light beam is obstructed or misaligned while the door is closing, the door will reverse. If the door is already open, it will not close.
The sensors can be aligned by loosening the wing nuts, aligning the sensors, and tightening the wing nuts. Check to make sure the LEDs in both sensors are glowing steadily. The LEDs in both sensors will glow steadily if they are aligned and wired correctly.

Operation

If either of the sensor LEDs are off, there is no power to the sensor:

Check that you have power to the garage door opener.
Check the sensor wire is not shorted or broken.
Check that the sensors are wired correctly; white wires to white terminal and white/black wires to grey terminal.

If the green receiving sensor LED is blinking, the sensors are obstructed or misaligned:

Check for obstructions in the sensor light beam.
Align the sensors.
If the receiving sensor (green LED) faces direct sunlight, switch the sensors to opposite sides of the door to assure proper operation.

Adjustment

Introduction

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

ncorrect 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.

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 back 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

WARNING

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 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 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.

Automatic Force Set Up

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.

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 imprperly 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 inspection and testing of your garage door and opener system a part of your regular 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 attempt 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.
