Installation

1 Determine the Header Bracket Location

WARNING

To prevent possible SERIOUS INJURY or DEATH:

  • Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling, otherwise garage door might NOT reverse when required. DO NOT install header bracket over drywall.
  • Concrete anchors MUST be used if mounting header bracket or 2×4 into masonry.
  • NEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or their hardware, ALL of which are under EXTREME tension.
  • ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garage door might NOT reverse when required.
  • DO NOT enable the Timer-to-Close functionality if operating either one-piece or swinging garage doors. To be enabled ONLY when operating a sectional door.

Close the door and mark the inside vertical centerline of the garage door. Extend the line onto the header wall above the door. You can fasten the header bracket within 4 feet (1.22 m) of the left or right of the door center only if a torsion spring or center bearing plate is in the way; or you can attach it to the ceiling when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2″ (1 cm). If you need to install the header bracket on a 2×4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2×4 to structural supports.

Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall 2″ (6 cm) above the high point. This height will provide travel clearance for the top edge of the door.

NOTE: If the total number of inches exceeds the height available in your garage, use the maximum height possible, or refer to page 14 for ceiling installation.

2. Install the Header Bracket

You can attach the header bracket either to the wall above the garage door, or to the ceiling. Follow the instructions which will work best for your particular requirements. Do not install the header bracket over drywall. If installing into masonry, use concrete anchors (not provided)

OPTION A – WALL INSTALLATION

  1. Center the bracket on the vertical centerline with the bottom edge of the bracket on the horizontal line as shown (with the arrow pointing toward the ceiling).
  2. Mark the vertical set of bracket holes (do not use the holes designated for ceiling mount). Drill 3/16″ pilot holes and fasten the bracket securely to a structural support with lag screws.

OPTION B – CEILING INSTALLATION

  1. Extend the vertical centerline onto the ceiling as shown.
  2. Center the bracket on the vertical mark, no more than 6″ (15 cm) from the wall. Make sure the arrow is pointing toward the wall. The bracket can be mounted flush against the ceiling when clearance is minimal.
  3. Mark the side holes. Drill 3/16″ pilot holes and fasten bracket securely to a structural support with the hardware provided.

WARNING

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.

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS

The safety reversing sensors must be connected and aligned correctly before the garage door opener will move in the down direction.

The sending sensor (with an amber LED) transmits an invisible light beam to the

receiving sensor (with a green LED). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to the full open position, and the garage door opener lights will flash 10 times.

NOTE: For energy efficiency the garage door opener will enter sleep mode when the door is fully closed. The sleep mode shuts the garage door opener down until activated. The sleep mode is sequenced with the garage door opener lights; as the lights turns off, the sensor LEDs will turn off and whenever the garage door opener lights turn on, the sensor LEDs will light. The garage door opener will not go into the sleep mode until the garage

door opener has completed 5 cycles upon power up. 

When installing the safety reversing sensors check the following:

  • Sensors are installed inside the garage, one on either side of the door.
  • Sensors are facing each other with the lenses aligned and the receiving sensor lens does not receive direct sunlight.
  • Sensors are no more than 6 inches (15 cm) above the floor and the light beam is unobstructed.

1 Install the Safety Reversing Sensors

The safety reversing sensors can be attached to the door track, the wall, or the floor. If the door track will not support the sensor bracket a wall installation is recommended. Choose one of the following installations.

OPTION A – DOOR TRACK INSTALLATION

  1. Slide the curved arms of the sensor bracket around the edge of the door track.
  2. Snap into place so that the sensor bracket is flush against the track.
  3. Slide the carriage bolt into the slot on each sensor.
  4. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket.

OPTION B – WALL INSTALLATION

If additional clearance is needed an extension bracket (not provided) or wood blocks can be used. Make sure each bracket hs the same amount of clearance so they will align correctly.

  1. Position the sensor bracket against the wall with the curved arms facing the door. Make sure there is enough clearance for the beam to be unobstructed. Mark holes.
  2. Drill 3/16 inch pilot holes for each sensor bracket and attach the sensor brackets to the wall using lag screws (not provided).
  3. Slide the carriage bolt into the slot on each sensor.
  4. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket.

OPTION C – FLOOR INSTALLATION

Use an extension bracket (not provided) or wood block to raise the sensor bracket if needed.

  1. Carefully measure the position of both sensor brackets so they will be the same distance from the wall and unobstructed.
  2. Attach the sensor brackets to the floor using concrete anchors (not provided).
  3. Slide the carriage bolt into the slot on each sensor.
  4. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket.

To avoid installation difficulties, do not activate the garage door opener at this time.

To reduce the risk of electric shock, your garage door opener has a grounding type plug with a third grounding pin. This plug will only fit into a grounding type outlet. If the plug doesn’t fit into your outlet, contact a qualified electrician to install the proper outlet.

THERE ARE TWO OPTIONS FOR CONNECTING POWER:

OPTION A – TYPICAL WIRING

  1. Plug in the garage door opener into a grounded outlet.
  2. DO NOT run garage door opener at this time.

OPTION B – PERMANENT WIRING

If permanent wiring is required by your local code, refer to the following procedure. To make a permanent connection through the 7/8 inch hole in the top of the motor unit (according to local code):

  1. Remove the motor unit cover screws and set the cover aside.
  2. Remove the attached 3-prong cord.
  3. Connect the black (line) wire to the screw on the brass terminal; the white (neutral) wire to the screw on the silver terminal; and the ground wire to the green ground screw. The opener must be grounded.
  4. Reinstall the cover.

2 Ensure the Safety Reversing Sensors are Aligned

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 and the garage door opener lights will flash ten times. 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.

  1. 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.

IF THE AMBER LED ON THE SENDING SENSOR IS NOT GLOWING:

  1. Make sure there is power to the garage door opener.
  2. Make sure the sensor wire is not shorted/broken.
  3. Make sure the sensor has been wired correctly: white wires to white terminal and white/black wires to gray terminal.

IF THE GREEN LED ON THE RECEIVING SENSOR IS NOT GLOWING:

  1. Make sure the sensor wire is not shorted/broken.
  2. Make sure the sensors are aligned.

3 Ensure the Door Control is Wired Correctly

If the door control has been installed and wired correctly, the command LED behind the push bar will blink.

Adjustments

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.

CAUTION

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 doors 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 left side panel of the garage door opened and are used to program the travel. While programming, the UP and DOWN buttons can be used to move the door as needed.

Features

Your garage door opener is equipped with features to provide you with greater control over your garage door operation.

Alert2Close

The Alert2Close feature provides a visual and an audible alert that an unattended door is closing.

TIMER-TO-CLOSE (TTC)

The TTC feature automatically closes the door after a specified time period that can be adjusted using a TTC enabled door control (Models 881LMW or 880LMW). Prior to and during the door closing the garage door opener lights will flash and the garage door opener will beep.

myQ

myQ allows you to control your garage door opener from your mobile device or computer from anywhere. myQ technology uses a 900Mhz signal to provide two way communication between the garage door opener and myQ enabled accessories. The garage door opener has an internal gateway that allows the garage door opener to communicate directly with a home Wi-Fi® network and access your myQ account.

THE PROTECTOR SYSTEM” (SAFETY REVERSING SENSORS)

When properly connected and aligned, the safety reversing sensors will detect an obstruction in the path of the infrared beam. If an obstruction breaks the infrared beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times. If the door is fully open, and the safety reversing sensors are not installed, or are misaligned, the door will not close from a remote control.

However, you can close the door if you hold the button on the door control or keyless entry until the door is fully closed. The safety reversing sensors do not affect the opening cycle. For more information see page 23.

ENERGY CONSERVATION

For energy efficiency the garage door opener will enter sleep mode when the door is fully closed. The sleep mode shuts the garage door opener down until activated. The sleep mode is sequenced with the garage door opener light bulb; as the light bulb turns off the sensor LEDs will turn off and whenever the garage door opener lights turn on the sensor LEDs will light. The garage door opener will not go into the sleep mode until the garage

door opener has completed 5 cycles upon power up.

LIGHTS

The garage door opener light bulbs will turn on when the opener is initially plugged in; power is restored after interruption, or when the garage door opener is activated. The lights will turn off automatically after 4-1/2 minutes. An incandescent A19 light bulb (100 watt maximum) or for maximum energy efficiency a 26W (100W equivalent) compact fluorescent light (CFL) bulb may be used.

Light Feature
