The door will travel to the full open position but will not return to the close position until the safety reversing sensors are connected and properly aligned. See page 13.13 The safety reversing sensor must be connected and aligned correctly before the door operator 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 page16. 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 full open position. The sensors must be installed inside the building so that the sending and receiving eyes 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. If it is necessary to mount the units 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. Install The Protector System

Installation 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.

• After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.8 cm) object (or 2x4 laid flat) on floor.

PROGRAMMING BUTTONS UP Button Adjustment Button DOWN Button To prevent damage to vehicles, be sure fully open door provides adequate clearance. Automatic Force Setup

1. 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. 2. 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 program the travel:

• Ensure the cable tension monitor is correctly installed (see page 10).

• Check to see if the safety reversing sensors are misaligned or obstructed (refer to page 17). When the sensors are aligned and unobstructed, cycle the door through a complete up and down cycle using the remote control or the UP and DOWN buttons. If you are unable to operate the door up and down, repeat the steps above.21 TEST

1. With the door fully open, place a 1-1/2" (3.8 cm) board (or a 2x4 laid flat) on the

floor, centered under the door.

2. Operate the door in the down direction. The door MUST reverse when it makes

contact with the board. ADJUST If the door stops but does not reverse:

1. Review the installation instructions provided to insure all steps were followed;

2. Repeat Program the Travel (see Adjustment Step 1);

3. Repeat the Safety Reversal test. If the test continues to fail, call a trained door

systems technician. IMPORTANT SAFETY CHECK: Test the Safety Reverse System after:

• Each adjustment of limits.

• Any repair to or adjustment of the door (including springs and hardware).

• Any repair to or buckling of the floor.

• Any repair to or adjustment of the operator. Test the Safety Reversal System Test the Protector System

Remote Controls Up to 40 Keyless Entries Up to 4 myQ Accessories Up to 16 Operation 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 13.

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.25 Programming Remote Control (Not Provided) Up to 40 Security+ 2.0 remote controls can be programmed to the door operator.

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

• Are the wiring connections correct? Review Installation Step4.

• 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. 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 byitself:

• 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 (replace), or there is an intermittent short in the wire.

• Erase the memory and reprogram all remote controls. 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:

• 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<OV>). Repeat the safety reverse test after the adjustment iscomplete. The door reverses for no apparent reason:

• 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:

• Reprogram limits see Adjustment Step 1. The door operator moves when the door is in operation:

• Minor movement for this operator is normal as long as it is not excessive.

• Check all mounting hardware to the door operator and/ or operator mounting brackets. Verify the operator is mountedat a right angle to the door shaft, sprocket and chain are aligned. 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.29
