IMPORTANT SAFETY INFORMATION

Important Safety Information will follow the words CAUTION and WARNING which are used to emphasize potentially hazardous situations.
CAUTION
This type of warning note is used to indicate the possibility of damage to the garage door or garage door opener.
WARNING
This type of warning note is used to indicate possible mechanical hazards that may cause serious injuries or death.
WARNING
Children operating or playing with a garage door opener can injure themselves or others. The garage door could cause serious injury or death. Do not allow children to operate the remote control(s) or the wall station. Install the wall station out of reach of children and away from all moving parts of the door. The door must be clearly visible from the wall station. A moving garage door could injure someone under it. Only activate the door when it is properly adjusted, when it can be seen clearly, and when there are no obstructions to the door travel.
WARNING
IMPORTANT SAFETY INSTRUCTIONS
Garage doors are large and heavy objects that move with the help of springs under high tension and electric motors. Since moving objects, springs under tension, and electric motors can cause injuries, your safety and the safety of others depends on you reading the information in this installation manual. If you have questions or do not understand the information presented, call Linear PRO Access Technical Support at 1-800-543-1236.
TO REDUCE THE RISK OF SEVERE INJURY OR DEATH TO PERSONS, REVIEW THIS INSTALLATION SAFETY STEPS BEFORE PROCEEDING.

1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2. Never let children operate or play with door controls. Keep the remote control away from children.
3. Always keep the moving door in sight and away from people and objects until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR.
5. Test the door monthly. The garage door MUST reverse on contact with a 1-1/2 inch high object (ir 2 x 4 board laid flat) on the floor. After adjusting either the force or the limit of travel, retest the door opener. Failure to adjust the opener properly increases the risk of severe injury or death.
6. For products having an emergency release, when possible, use the emergency release only when door is closed. Use caution when using this release with the door open. Weak or broken springs are capable of increasing the rate of door closure and increasing the risk of severe injury or death.
7. KEEP GARAGE DOORS PROPERLY BALANCED. See user’s manual. An improperly balanced door increases the risk of severe injury or death. Have a qualified service person make repairs to cables, spring assemblies, and other hardware.
8. For operator systems equipped with an unattended operation feature, the following statement shall be included: “This operating system is equipped with an unattended operation feature. The door could move unexpectedly. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR”.

TESTING THE SAFETY BEAM

WARNING

• Photo beams MUST be installed on the garage door to prevent serious injury or death.
• This required safety reversing sensor MUST NOT be disabled at any time.
• Photo beams should be installed no higher than 6” above the floor.

The safety beam has two components, a sender and a receiver. The sender produces a narrow infrared beam that travels across the bottom of the door opening to the infrared receiver. If an object blocks the infrared beam while the door is closing, the door will stop, then reverse and fully open (the opener’s light will flash three times).

As a safety feature, the opener will ignore signals from all remote controls if the door is open and the infrared safety beam is blocked or out of alignment. In this case, the door can be forced closed by pressing and holding the wall station’s up/down arrow pushbutton (be sure the door area is in clear view).

Safety Beam Test

1. Check that the opener has power. The green lights on the sender and receiver should be lit.

2. If the receiver’s green light is on, but the red light is off, the receiver has power but is not detecting the infrared beam from the sender. The red light might flash when the beam is partially detected. This can be caused by misalignment or something blocking the beam. Adjust the safety beam sender and receiver while watching the receiver’s red light (stay out of the beam while aligning it). When the red light stays on, rotate the sender towards the ceiling and stop when the red light on the receiver begins to flicker. Rotate the sender back towards a horizontal position with the floor and stop as soon as the red light on the receiver lights solid.  The beam is now properly aligned.
   NOTE: If the receiver’s red light remains off, check for: 1) Dirt on the receiver’s lens, 2) Sunlight shining into the receiver’s lens, 3) A short in the safety beam wiring (from staples or at the opener terminals).

3. • Press the remote control button to open the garage door.
   • Place a box in the path of the safety beams.
   • Press the remote control button to close the door. The door will not move and the opener‘s lights will flash and beep.

4. The garage door opener will not close if the beams are misaligned or obstructed.

SAFETY BEAM INDICATOR TABLE

GREEN ON| POWER ON
GREEN OFF| POWER OFF
RED ON| BEAM OK – NO BLOCKAGE
RED OFF| BEAM BLOCKED OR MIS-ALIGNED
RED FLASHING| BEAM ALIGNED POORLY

IMPORTANT: If the garage door closes when the safety beam is obstructed, call a professional garage door technician.

ADJUSTING THE OPEN AND CLOSE LIMITS

The limit settings control how far the door will open or close. The limits should be set so the door opens even with the door opening, and closes at the floor level.
If required, use the following steps to adjust the limits.
After beginning to adjust the limits, if no buttons are pressed for one minute, the opener will return to normal operation.

CAUTION
Set the open and close limits carefully. Setting the limits beyond the distance that the door can travel could cause damage to the door, the door hardware, or the operator.

Adjusting the Open Limit

1. Use the wall station or remote control to move the door to the open limit position.
2. On the back of the opener, press both the UP and LEARN buttons for three seconds. The green indicator and opener’s light will flash twice then stay on.
3. Use the UP and DOWN buttons to jog the door at slow speed to fine-tune the open limit position.
4. When the door is at the proper open limit position, press the LEARN button to store the setting and exit setup. The green indicator and the opener’s light will flash two times.

Adjusting the Close Limit

1. Use the wall station or remote control to move the door to the close limit position.
2. On the back of the opener, press both the DOWN and LEARN buttons for three seconds. The RED LED and opener’s light will flash twice then stay on.
3. Use the UP and DOWN buttons to move the door at slow speed to fine-tune the close limit position.
4. When the door is at the proper close limit position, press the LEARN button to store the setting and exit setup. The RED LED and the opener’s light will flash two times.

NOTE: If the opener is field reset, both the open and close limits must be adjusted and the automatic door force setup must be completed for proper operation.

AUTOMATIC DOOR FORCE SETUP

(normally not used)
The opener automatically measures the door force throughout the entire travel of the door each time the opener cycles. The opener will automatically adjust to changing door hardware conditions over time due to weather and wear. Your installer has used these steps during setup of the opener. You can also perform these steps at any time.

Automatic Door Force Setup

1. Be sure that the trolley latch is up and the door is connected to the opener.
2. Operate the door through four (4) complete open and close cycles.

SAFETY REVERSAL SYSTEM TEST

The opener determines that there is obstruction if a higher than expected amount of force is detected during a door cycle. If an obstruction is encountered during a closing cycle, the opener and door will stop when fully open. If an obstruction is encountered during an opening cycle, the opener and door will stop.

Safety Reversal System Test

1. Lay a 2 x 4 board flat on the floor where it will be struck by the center of the door as it closes.
2. Verify that the door reverses when it strikes the board. The door must reverse within two seconds after striking the board.

PROGRAMMING REMOTE CONTROLS

The opener is supplied with a three-button remote control (the second and third buttons can be used to control additional openers or gates). Additional single and multi-button remote controls can be purchased. The short wire on the back of the opener serves as an antenna for the remote controls. Do not cut off the wire or the remote controls will not operate well.

To Add or Remove a Remote Control

1. Press the opener’s LEARN button. The opener’s light and red light will flash once and turn on for about 15 seconds. The remote control must be added or removed while the red light is still on.
2. Send a signal from a remote control. The opener’s light and the red light will flash once if a remote control was added, or the opener’s light and the red light will flash four times if a remote control was removed.
3. Repeat Steps 1 & 2 for any additional remote control controls.

To Remove All Remote Controls

1. Press and hold the opener’s LEARN button for ten seconds or more.
2. Release the LEARN button. The red light and opener’s light will blink three times signaling that all of the remote controls in the opener’s memory were erased. The red light will turn off, then turn on for 15 seconds. Remote control can be entered during this time using the steps above.

Testing

1. Before testing the remote control, straighten out the opener’s antenna wire so it points up.
2. Stand clear of the door, press the remote control’s button and verify that the opener starts. PRESS THE

REMOTE CONTROL’S BUTTON AGAIN TO STOP THE DOOR MID-TRAVEL.

Replacing a Remote Control’s Battery

MAINTENANCE

Weather conditions may affect the door operation which could require some re- setting of the opener’s adjustments. Doors may swell and become heavier during wet periods, door hinges and rollers might bind during cold periods. To ensure the safe operation of the door, perform the following tests, including any additional test steps described.

Every Month

1. With the door closed, pull the red release handle to disconnect the opener from the door.

2. From outside the garage, slowly open the door manually all the way, and then close it all the way.
   Notice if there is any binding, sticking or rubbing. The door should move smoothly in both directions.

3. Raise the garage door about halfway up. Carefully release the door and see if the door balances. It should stay in place. Close the door.
   NOTE: If the garage door is unbalanced or the door travel isn’t smooth, have a qualified garage door professional adjust or repair the door.

4. To reconnect the opener, with the door closed flip the release lever up and run the opener.

After Servicing the Opener

1. Perform the Safety Beam Test.
2. Perform the Open and Close Limit Adjustments.
3. Perform the Safety Reversal System Test.

Every 6 Months
Check the belt or chain tension.

• For belt-drive rails, examine the length of the tension spring in the traveler. It should be about 1” long.
• For chain-drive rails, examine the spacing between the turnbuckle and the rail. The turnbuckle should be slightly above the bottom of the rail.

NOTE: Too much or too little chain tension will cause excessive sprocket noise.

Belt Adjustment
The tension spring in the traveler keeps the belt taut. The factory setting for the tension spring length is .9” long. If the tension spring is longer than 1”, adjust the belt.

1. Hold the traveler so the adjustment wheel is visible through the large slot.
2. Use a flat blade screwdriver to turn the adjustment wheel to compress the tension spring until its length is between 0.9” and 1” long.
