  3. Re-assemble the remote.

Garage Door Opener 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 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, flip the release lever up and run the opener.

  5.  Perform the Safety Beam Test (Section 4).

  6. Perform the Safety Reversal System Test as described in Section 8.

WARNING

  • Garage door hardware (springs, cables, brackets, pulleys, etc.) are under extreme pressure and tension. DO NOT ATTEMPT TO LOOSEN, TIGHTEN OR ADJUST ANY DOOR HARDWARE. CALL A QUALIFIED GARAGE DOOR INSTALLATION PROFESSIONAL!
  • The garage door opener must not be installed and used on an unbalanced door. The opener’s internal door force sensor will not function properly on an unbalanced door. Risk of serious injury or death may result.

After Servicing the Opener

  1. Perform the Safety Beam Test (Section 4).
  2. Perform the Open and Close Limit Adjustments (Section 5).
  3. Perform the Safety Reversal System Test (Section 8).LINEAR-LDCO801-Belt-Drive-Or-Chain-Drive-DC-Motor-Garage-Door-Opener-fig-6

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

Chain Adjustment

  1. If necessary, use the following steps to adjust the chain. 1 Hold the turnbuckle with a flat blade screwdriver and loosen the two locknuts with a 7/16” end wrench.
  2. Twist the turnbuckle to adjust the chain tension. Adjust the chain until the turnbuckle is sightly above the rail. 3 Hold the turnbuckle with a flat blade screwdriver and tighten the two locknuts with a 7/16” end wrench.

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 .9” and 1” long.
    Every Year Check the door hardware for lubrication needs. Lubricate door hinges, rollers and bearings according to door manufacturer’s recommended procedures. LINEAR-LDCO801-Belt-Drive-Or-Chain-Drive-DC-Motor-Garage-Door-
Opener-fig-7

Testing the Infrared Safety Beam

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).

WARNING
With the door closed, disengage the trolley from the chain during these alignment tests by pulling the red release handle.

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 mis-alignment 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. With the door closed and the opener disengaged from the door, press the wall station’s UP/DOWN ARROW button to move the traveler (the part on the belt or chain that the trolley engages with) to the up position (away from the door). NOTE: Do not cycle the opener to full travel without the door connected.

  4. Push the wall station’s UP/DOWN ARROW button again. While the traveler is moving to the down position (toward the door), block the safety beam. THE TRAVELER MUST STOP, THEN REVERSE TO THE UP POSITION. The opener’s light and red light should flash three times.

  5. Place an object in the path of the safety beam. Check that constant pressure is required on the wall station’s UP/DOWN ARROW button to cause the traveler to move toward the down position. Release the pushbutton before the opener stops; check that the traveler returns to the up position.
    NOTE: The garage door opener will not respond to a CLOSE command from a remote control if the safety beam is blocked.

  6. To reconnect the opener, flip the release lever up. Raise the door manually until the opener reconnects.

ADJUSTING THE BEAM

  1. ADJUST THE SENDER AND RECEIVER UNTIL THE RED INDICATOR LIGHTS SOLID
  2. ADJUST SENDER UP UNTIL RECEIVER’S RED INDICATOR FLASHES
  3.  ADJUST SENDER DOWN JUST UNTIL RECEIVER’S RED INDICATOR LIGHTS SOLID

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 just short of any door stops, 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.

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 indicator and opener’s light will flash twice and then stay on

  3. Use the UP and DOWN buttons to jog 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 indicator and the opener’s light will flash two times.

Replacing the Opener’s Lamp

If the opener’s safety lamp fails to light manually or when the opener is cycled, the light bulb needs replacing. Use the following steps to replace the light bulb.

  1. Remove the light cover to expose the light bulb and lamp socket.
  2. Replace the light bulb with a 100-watt maximum rough service bulb (sometimes called a garage door bulb).
  3. Reattach the light cover.
  4. Press the wall station’s lamp button to test the lamp.

Automatic Door Force Setup

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.

WARNING
STAY CLEAR OF THE DOOR DURING THIS PROCEDURE!

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 complete open and close cycles.
    CAUTION Do not cycle the opener full travel without the door connected. The automatic door force setting will adjust to the unloaded condition and may trip the safety system when the door is reconnected.

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 then 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.
    WARNING Always perform the Safety Reversal System Test after making any adjustments to the opener. PERFORM THE SAFETY REVERSAL SYSTEM TEST MONTHLY!

Adjusting the Force Factor (Installation Option, Normally Not Used)

The opener uses the peak force measured during each of the last four complete cycles plus a “force factor” to calculate the maximum allowed force setting for the current door cycle. If the calculated maximum force setting is exceeded during the current door cycle, the opener reacts to the obstruction. As door hardware conditions change over time with weather and wear, the calculation of the maximum door force setting using the four cycle running average will compensate for the current conditions of the installation.

Changing the Force Factor Setting
As an installation option, the opener’s “force factor” can be adjusted to change the amount of pressure exerted on an obstacle before the opener reacts to the obstruction.

  1. Press both the UP and DOWN buttons for three seconds. The red and green indicators and opener’s light will flash twice.
  2. Use the UP or DOWN buttons to set the force factor. Pressing the UP button increases the force factor, pressing the DOWN button decreases the force factor.
    FORCE FACTOR INDICATOR TABLE

    GREEN ON| LOW FORCE FACTOR
    RED & GREEN ON| MEDIUM FORCE FACTOR
    RED ON| HIGH FORCE FACTOR

  3. After selecting the force factor, press the LEARN button to store the setting and exit setup. The red and green indicators and the opener’s light will flash two times. (If the force factor is not set within one minute, the opener will return to normal operation at its previous force factor setting.)
  4. After changing the force factor setting, perform the Safety System Reversal Test.

Field Reset

In installations where the door spring, door, or hardware is being replaced, and the opener was already programmed for the old door, reset the opener using the following steps.

  1. Press and hold down the UP, DOWN, and LEARN  buttons at the same time for ten seconds. The red and green indicators and the opener’s light will flash twice.
  2. Release the buttons. The opener will reset the force settings and erase all set limits, but will still retain all programmed remote controls in memory.
  3. AFTER PERFORMING A FIELD RESET, BOTH THE OPEN AND CLOSE LIMITS MUST BE ADJUSTED AND THE AUTOMATIC DOOR FORCE SETUP COMPLETED BEFORE THE OPENER WILL FUNCTION.
