6. Install the Protector System

WARNING

Be sure power is NOT connected to the door operator BEFORE installing the safety reversing sensor.

To prevent SERIOUS INJURY or DEATH from a closing 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 floor.

The safety reversing sensor must be connected and aligned correctly before the door will move in the down direction. This is a required safety device and cannot be disabled. The LiftMaster Light Curtain LC36A may be installed as an optional secondary safety device, see page 15.

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS

When properly connected and aligned, the safety reversing sensor will detect an obstacle in the path of its electronic beam. The sending sensor (with an amber indicator light) transmits an invisible light beam to the receiving sensor (with a green indicator light).

If an obstruction breaks the light beam while the door is closing the door will stop and reverse to the full open position.

The sensors must be installed inside the building so that the sending and receiving sensors face each other across the door, no more than 6" (15 cm) above the floor. Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving sensor lens.

The mounting brackets are designed to clip onto the track of sectional doors without additional hardware.

If it is necessary to mount the sensors on the wall, the brackets must be securely fastened to a solid surface such as the wall framing. Extension brackets (see accessories) are available if needed. If installing in masonry construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is necessary.

The invisible light beam path must be unobstructed. No part of the door (door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing.

Facing the door from inside the building.

INSTALLING THE BRACKETS

Be sure power to the operator is disconnected. Install and align the brackets so the safety reversing sensors will face each other across the door, with the beam no higher than 6" (15 cm) above the floor. Choose one of the following installations.

OPTION A: TRACK INSTALLATION

1. Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door. Snap into place against the side of the track. It should lie flush, with the lip hugging the back edge of the track, as shown.

If your door track will not support the bracket securely, wall installation is recommended.

OPTION B: WALL INSTALLATION

1. Place the bracket against the wall with curved arms facing the door. Be sure there is enough clearance for the sensor beam to be unobstructed.

2. If additional depth is needed, an extension bracket (see Accessories) or wood blocks can be used.

3. Use bracket mounting holes as a template to locate and drill (2) 3/16" diameter pilot holes on the wall at each side of the door, no higher than 6" (15 cm) above the floor.

4. Attach brackets to wall with lag screws (not provided).

If using extension brackets or wood blocks, adjust right and left assemblies to the same distance out from the mounting surface. Make sure all door hardware obstructions are cleared.

OPTION C: FLOOR INSTALLATION

1. Use wood blocks or extension brackets (see Accessories) to elevate sensor brackets so the lenses will be no higher than 6" (15 cm) above the floor.

2. Carefully measure and place right and left assemblies at the same distance out from the wall. Be sure all door hardware obstructions are cleared.

3. Fasten to the floor with concrete anchors as shown.

Using Your Door Operator

FEATURES

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

myQ

myQ allows you to control your door operator from your mobile device or computer from anywhere. myQ technology uses a 900Mhz signal to provide two way communication between the door operator and myQ enabled accessories. The door operator has an internal gateway that allows the door operator 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. 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 12.

ENERGY CONSERVATION

For energy efficiency the door operator will enter sleep mode when the door is fully closed. The sleep mode shuts the door operator down until activated. When the door operator enters sleep mode, the sensor LEDs will turn off and whenever the door operator is activated, the sensor LEDs will light. The door operator will not go into the sleep mode until the door operator has completed 5 cycles upon power up.

USING YOUR DOOR OPERATOR

The door operator can be activated through a wall-mounted door control, remote control, wireless keyless entry or myQ accessory. When the door is closed and the door operator is activated the door will open. If the door senses an obstruction or is interrupted while opening the door will stop. When the door is in any position other than closed and the door operator is activated the door will close. If the door operator senses an obstruction while closing, the door will reverse. 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. The safety reversing sensor must be connected and aligned correctly before the door operator will move in the down direction.

BATTERY BACKUP (OPTIONAL)

The battery backup system allows access in and out of your building, even when the power is out. When the door operator is operating on battery power, the door operator will run slower, the Battery Status LED will glow solid orange, and a beep will sound approximately every 2 seconds.

MEMORY CAPACITY

Troubleshooting

Diagnostic Chart

Your door operator is programmed with self-diagnostic capabilities. The UP and DOWN arrows on the door operator flash the diagnostic codes.

Additional Troubleshooting

The door operator doesn't operate from the single button control station:

• Does the door operator have power? Plug a lamp into the outlet. If it doesn't, check the fuse box or the circuit breaker. (Some outlets are controlled by a wall switch.)

• Have you disabled all door locks? Review installation instruction warnings on page 7.

• Are the wiring connections correct? Review Installation Step 5.

• Is there a build-up of ice or snow under the door? The door may be frozen to the ground. Remove any restriction.

• The door spring may be broken. Have it replaced (see page 3 for reference).

The door operator operates from the single button control station, but not from a remote control:

• Reprogram the remote control and replace the battery if necessary. Repeat with all remote controls.

The door opens and closes by itself:

• Be sure that all remote control push buttons are off.

• Remove the bell wire from the single button control station terminals and operate from the remote only. If this solves the problem, the single button control station is faulty, or there is an intermittent short in the wire. Replace the control station.

• Erase the memory and reprogram all remote controls (refer to the instructions provided with the remote control or visit LiftMaster.com).

The door doesn't open completely:

• Disable any door locks.

• Is something obstructing the door? Is it out of balance, or are the springs broken? Remove the obstruction or repair the door.

The door opens but won't close:

• Check that cable tension monitor is correctly installed. If a second cable tension monitor has been removed, follow the instructions to relearn a single cable tension monitor (See Installation Step 4).

• The safety reversing sensor must be connected and aligned correctly before the door operator will move in the down direction. If you are able to close the door using constant pressure, verify the safety reversing sensors are properly installed, aligned and free of any obstructions (see page 17).

Repeat the safety reverse test after the adjustment is complete.

The door reverses for no apparent reason:

• Check that cable tension monitor is correctly installed. If a second cable tension monitor has been removed, follow the instructions to relearn a single cable tension monitor (See Installation Step 4).

• Is something obstructing the door? Pull the emergency release handle. Operate the door manually. If it is unbalanced or binding, call a trained door systems technician.

• Clear any ice or snow from the floor area where the door closes. Repeat safety reverse test after adjustments.

The door operator strains to operate door:

• The door may be out of balance or the springs may be broken. Close the door and use the emergency release handle to disconnect the door. Open and close the door manually. A properly balanced door will stay in any point of travel while being supported entirely by its springs. If it does not, disconnect the door operator and call a trained door systems technician.

The door operator motor hums briefly, then won't work:

• The door springs may be broken. See above.

• If the problem occurs on the first operation of the door operator, door may be locked. Disable any door locks.

The door operator won't operate due to power failure:

• Disable any door locks. Use the emergency release handle to disconnect the door. The door can be opened and closed manually.

When power is restored, pull manual release a second time.

• When in battery backup mode, battery power will last for 30 hours or up to 20 cycles over a 24 hour period.

Door loses limits:

• Collar not tightened securely. Tighten collar and reprogram limits (see Adjustment Step 1). The door operator moves when the door is in operation:

• Some minor movement is normal for this product. If it is excessive the collar will wear prematurely.

• Check to make sure the torsion bar is not moving left/right excessively.

• Check to make sure the torsion bar is not visibly moving up and down as it rotates.

• Check that the door operator is mounted at a right angle to the Jackshaft. If not, move the position of the mounting bracket.

Automatic door lock connector will not fit the door operator plug:

Older model 24V door locks are incompatible. Use automatic door lock model 841LM, see Accessories page 30.

The door operator is beeping:

• Indicates unattended closure. The operator has been activated by the myQ App or the Garage and Gate Monitor.

• A solid orange LED with beep, sounding approximately every 2 seconds, indicates the door operator is operating on battery power.

• A flashing orange LED with beep, sounding every 30 seconds, indicates the battery is low.

• A solid red LED with beep, sounding every 30 seconds, indicates the 12V battery will no longer hold a charge and needs to be replaced.
