Linear LCO75 Safety Beam Test, Every Month Disconnect the operator from the door, Every 6 Months

11 Aligning the Infrared Safety Beam

13 Adjusting the Open and Close Limits

15 Using the Garage Door Operator

16 Garage Door Operator Maintenance

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 operator’s light will fl ash three times).

As a safety feature, the operator 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 operator has power. The green lights on

WARNING

Serious injury or death from a closing garage door may result because of failure to test and adjust the safety reverse system. Repeat this test monthly and adjust as needed.

The limit adjustments that control how far the door will open or close are located on the side of the operator. The limits should be adjusted so the door opens just short of any door stops, and closes right at the fl oor level. Each full turn of a limit adjustment equals about 2-½” of door travel.

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 operator.

1 Activate the remote control. Wait while the door moves

IMPORTANT USER SAFETY INSTRUCTIONS

WARNING

A MOVING GARAGE DOOR CAN CAUSE INJURY OR DEATH!

TO REDUCE THE RISK OF DEATH OR SEVERE INJURY:

1	READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2	NEVER LET CHILDREN OPERATE, OR PLAY WITH DOOR CONTROLS! KEEP REMOTE CONTROL
	AWAY FROM CHILDREN!
3	Always keep 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.

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

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 fl ash 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, the beam is aligned.

5	Test door operator monthly.The garage door MUST reverse on contact with a 1-1/2 inch object (or a 2x4
	board laid flat at the center of the door) on the floor. If adjusting either the force or the limit of travel,
	re-test the door operator. Failure to adjust the operator properly may cause severe injury or death.
6	If possible, use the red emergency release handle only when the door is closed. Use caution when
	using this release with the door open. Weak or broken springs may cause the door to fall rapidly,
	causing injury or death.
7	KEEP GARAGE DOORS PROPERLY BALANCED. (See Garage Door Operator Maintenance) An
	improperly balanced door could cause severe injury or death. Have a qualified service person make
	repairs to cables, spring assembly and other hardware.
8	SAVE THESE INSTRUCTIONS.

➤NOTE: If the garage door is unbalanced or the door travel isn’t smooth, have a qualifi ed garage door professional adjust or repair the door.

4 To reconnect the operator, fl ip the release lever up. Raise the door manually until the operator reconnects.

5Perform the Safety Beam Test (Section 11).

6Perform the Safety Reversal System Test as described in Steps 4-6 in Section 14.

After Servicing the Operator

1	Perform the Safety Beam Test (Section 11).
2	Perform the	Open and Close Limit Adjustments
	(Section 13).

WARNING

The garage door operator must not be installed and used on an unbalanced door. The operator’s internal door force sensor will not function properly on an unbalanced door. Risk of serious injury or death may result.

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

If necessary, use the following steps to adjust the chain.

1	Hold the turnbuckle with a fl at 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.

The door force adjustments are located on the side of the operator. The door force adjustments must be properly set at all times. The CLOSE FORCE adjustment controls how much force is required to cause the door to reverse direction if an obstruction is encountered during closing. The OPEN FORCE adjustment controls how much force is required to stop the door if an obstruction is encountered during opening.

WARNING

Too much door force will interfere with the proper operation of the safety system. SOMEONE COULD BE SERIOUSLY INJURED OR KILLED IF THE DOOR FORCE IS SET TOO HIGH. A closing door

The operator is supplied with a three-button remote control (the second and third buttons can be used to control an additional operator or gate if it contains a Linear MegaCode™ receiver). Additional single and multi-button remote controls can be purchased. An unlimited number of remote controls can be used with this operator. The short wire on the back of the operator serves as an antenna for the remote controls. Do not cut off the short wire or the remote controls will not operate well.

1Press and hold the operator’s LEARN button for ten seconds or more.

2Release the LEARN button. The red LEARN light will blink three times signaling that all of the remotes in the operator’s memory were erased. The red LEARN light will turn off, then turn on for 15 seconds. A remote control can be entered during this time using Step 2 above.

Testing

1Before testing the remote control, straighten out the operator’s short antenna wire so it points up.

2Stand clear of the door, press the remote control’s button and verify that the operator starts. PRESS THE

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

3Set the open and close limits as described in the next section before any further testing.

Replacing a Remote Control’s Batteries

When the red light on the remote glows dimly, or fails to light at all when the remote is activated, the batteries need replacing.
