WARNING

CAUTION

Page 3

To avoid damage to the garage door and opener, disable locks before installing and operating the opener. Use a wood screw or nail to hold locks in the "open" (unlocked) position.

Operation at other than 120V 60 Hz will cause opener malfunction and damage.

WARNING

An unbalanced garage door might not reverse when required and someone under the door could be seriously injured or killed.

If your garage door binds, sticks or is out of balance, call for professional garage door service.

Garage doors, door springs, cables, pulleys, brackets and their hardware, are under extreme tension and can cause serious injury or death.

Do not try to loosen, move or

adjust them yourself!

Ropes left on a garage door could cause someone to become entangled and killed.

Remove all ropes connected to the door before installing and operating the opener.

Test your door for balance

Before you begin, complete the following test to make sure your door is balanced, and is not sticking or binding:

• Lift the door about halfway as shown. Release the door. It should stay in place, supported entirely by its springs.

• Raise and lower the door to see if there is any binding or sticking.

Planning

Identify the type and height of your door, any special conditions that exist, and any additional materials that may be required, by referring to page 4.

Installation Step 6

Install the Door Control

Outside Keylock Accessory Connections

To opener terminal screws: white to 2; white/red to 1

DO NOT CONNECT TO LIVE ELECTRICAL WIRING. CONNECT ONLY TO 24 VOLT LOW VOLTAGE WIRES. CONNECTION TO LIVE WIRES OR HIGHER VOLTAGE MAY CAUSE SERIOUS INJURY FROM SHOCK, BURN OR ELECTROCUTION.

Children operating or playing with a garage door opener can injure themselves or others. The garage door could close and cause serious injury or death. Do not allow children to operate the push button(s) or the remote control transmitter(s).

A moving garage door could injure someone under it. Activate the opener only when the door is properly adjusted, you can see it clearly, and there are no obstructions to door travel.

Locate the door control within sight of the door at a minimum height of 5 feet where small children cannot reach, and away from all moving parts of the door and door hardware.

The door control is typically attached directly to the wall. If installing into drywall, drill 5/32" holes and use the anchors provided. For pre-wired installations (as in new home construction) it can be mounted to a standard single gang box. See illustrations.

1. Strip 1/4" of insulation from one end of the bell wire. Connect the wire to the two screw terminals on back of door control: white wire to 2 and white/red wire to 1.

2. Remove the push bar cover by gently prying off the top edge with a coin or screwdriver. Fasten with 6ABx1-1/4" self-tapping screws (standard installation) or 6-32x1" machine screws (pre-wired installation) as follows:

• Install bottom screw, allowing 1/8" to protrude from

the wall.

• Position bottom of door control on screw head and

adjust for snug fit.

• Install top screw with care to avoid cracking plastic

housing.

Do not overtighten.

3. (For standard wall mount only) Run the bell wire up wall and across ceiling to opener. Use insulated staples to secure the wire in several places. Be careful not to pierce the wire with a staple, creating a short.

4. Connect the bell wire to the terminal screws on the opener panel: white to 2 and white/red to 1.

5. After testing, replace the cover by inserting top tabs and snapping into place.

NOTE: After installation, the green indicator light behind the push bar cover will indicate proper connection.

The automatic light feature will become functional 1-1/2 minutes after power is restored.

6. Attach the User Safety Instruction label to the wall near the door control, and the Maintenance Instruction label in a prominent location on the inside of the garage door.

Page 28 explains how to use the door control.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Do not use the red handle to pull the door open or closed.

The rope knot could become

untied and you could fall.

Use the manual release only to disengage the trolley and, if possible, only when the door is closed.

Garage doors are heavy. If the door is open when the handle is pulled, the door could close inadvertently if it is not properly balanced. Serious injury may result to persons under the door. Make sure the doorway is clear of persons and obstructions before pulling handle when door is open.

• Thread one end of the rope through the hole in the

top of the red handle so "NOTICE" reads right side up as shown. Secure with an overhand knot at least 1" from the end of the rope to prevent slipping.

• Thread the other end of the rope through the hole in the release arm of the outer trolley.

• Adjust rope length so the handle is 6 feet above the floor. Secure with an overhand knot .

If it is necessary to cut the rope, heat seal the cut end with a match or lighter to prevent unraveling.

Without a properly working safety reversing sensor, persons (particularly children) could be injured or killed by a closing garage door.

Read

and follow all instructions. To protect small children, install the safety

reversing sensor so that the beam will be no higher than 4"-6" above the garage floor.

Disconnect power to the garage door opener before installing the safety reversing sensor.

Figure 1

: Facing the door from inside the garage

The Protector®System

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR

The safety reversing sensor

must

be connected and aligned correctly before the garage door opener will move in the down direction. This is a required safety device and cannot be disabled.

When properly connected and aligned, the safety reversing sensor will detect an obstacle in the path of its electronic beam. The sending eye (with an orange indicator light) transmits an invisible light beam to the receiving eye (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, and the door control will flash for 5 seconds.

The units must be installed inside the garage so that the sending and receiving eyes face each other across the door, between 4 – 6" 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 eye lens.

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

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 garage door (or door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing.

They may be installed in one of three ways, as follows.

Garage door track installation (preferred):

• 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 in Figure 2.

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

Wall installation:

• 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.

• If additional depth is needed, an extension bracket

(see Accessories) or wood blocks can be used.

• 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, from 4–6" above the floor.

• 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.

Floor installation:

• Use wood blocks or extension brackets (see

Accessories) to elevate sensor brackets so the lenses will be 4-6" above the floor.

• Carefully measure and place right and left

assemblies at the same distance out from the wall. Be sure all door hardware obstructions are cleared.

• Fasten to the floor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY SENSORS

• Slide a 1/4"-20x1/2" carriage bolt head into the slot

on each sensor. Use wing nuts to fasten sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension. See Figure 5.

• Finger tighten the wing nuts.

• Run the wires from both sensors to the opener. Use

insulated staples to secure wire to wall and ceiling.

• Strip 1/4" of insulation from each set of wires.

Separate white and white/black wires sufficiently to connect to the opener terminal screws: white to 2 and white/black to 3.

ALIGNING THE SAFETY SENSORS

• Plug in the opener. The indicator lights in both the

sending and receiving eyes will

glow steadily

wiring connections and alignment are correct.

The

sending

eye orange indicator light will glow regardless of alignment or obstruction. If the green indicator light in the

receiving eye

is off, dim, or flickering (and the invisible light beam path is not obstructed), alignment is required.

• Loosen the

sending

eye wing nut and readjust,

aiming directly at the receiving eye. Lock in place.

• Loosen the

receiving

eye wing nut and adjust sensor until it receives the sender’s beam. When the green indicator light

glows steadily,

tighten the

wing nut.

TROUBLESHOOTING THE SAFETY SENSORS

1. If the

sending eye

indicator light does not

glow

steadily

after installation, check for:

• Electric power to the opener.

• A short in the white or white/black wires. These can occur at staples, or at screw terminal connections.

• Incorrect wiring between sensors and opener.

• A broken wire.

2. If the sending eye indicator light

glows steadily

but

the receiving eye indicator light doesn't:

• Check alignment.

• Check for an open wire to the receiving eye.

3.If the receiving eye indicator light is dim, realign either sensor.

NOTE: When the invisible beam path is obstructed or misaligned while the door is closing, the door will reverse. If the door is already open, it will not close. The door control will blink 10 times. See page 17.

Installation Step 11

Fasten Door Bracket

Follow instructions which apply to your door type as illustrated below or on page 21.

To prevent damage to steel, aluminum, fiberglass or glass panel doors, always reinforce the inside of the door both vertically and horizontally with an angle iron.

A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should cover the height of the top panel.

The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron are used to create a "U"-shaped support. The best solution is to check with your garage door manufacturer for an opener installation door reinforcement kit.

• Center the door bracket on the previously marked vertical guideline used for the header bracket installation.

Note the correct UP placement, as

stamped inside the bracket.

• Position the bracket on the face of the door within the following limits:

A) The top edge of the bracket 2"-4" below the top

edge of the door.

B) The top edge of the bracket directly below any

structural support across the top of the door.

• Mark and drill 5/16" left and right fastening holes. Secure the bracket as shown in Figure 1 if there is vertical reinforcement.

If your installation doesn't require vertical reinforcement but does need top and bottom fastening holes for the door bracket, fasten as shown in Figure 2.

All ONE-PIECE Doors

On one-piece doors, before connecting the door arm to the trolley the travel limits must be adjusted. Limit adjustment screws are located on the left side panel as shown on page 24. Follow adjustment procedures below.

Adjustment Procedures for One-Piece Doors

Open Door Adjustment:

Decrease UP limit

• Turn the UP limit adjustment screw counterclockwise 5 1/2 turns.

• Press the Door Control push bar. The trolley will travel to the fully open position.

• Manually raise the door to the open position (parallel to the floor), and lift the door arm to the trolley. The arm should touch the trolley just in back of the door arm connector hole. Refer to the fully open trolley/door arm positions in the illustration. If the arm does not extend far enough, adjust the limit further. One full turn equals 2" of trolley travel.

Closed Door Adjustment:

Decrease DOWN limit

• Turn the DOWN limit adjustment screw clockwise 5 complete turns.

• Press the Door Control push bar. The trolley will travel to the fully closed position.

• Manually close the door and lift the door arm to the trolley. The arm should touch the trolley just ahead of the door arm connector hole. Refer to the fully closed trolley/door arm positions in the illustration. If the arm is behind the connector hole, adjust the limit further. One full turn equals 2" of trolley travel.

Connect the door arm to the trolley.

• Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. It may

be necessary to lift the door slightly to make the connection.

• Secure with a ring fastener.

• Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position as shown in the illustration, decrease the UP limit until the door is parallel to the floor.

Assemble the Door Arm:

• Fasten the straight and curved door arm sections

together to the longest possible length (with a 2 or 3 hole overlap).

• With the door closed, connect the straight door arm section to the door bracket with the 5/16"x1-1/4" clevis pin.

• Secure with a ring fastener.

Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the Safety Reversing Sensors are completely installed.

Limit adjustment settings regulate the points at which the door will

stop

when moving up or down.

The door will

stop

in the

direction if anything

interferes with door travel. The door will

reverse

the

down

direction if anything interferes with the

door travel (including binding or unbalanced doors). To operate the opener, press the Door Control push

bar. Run the opener through a complete travel cycle.

• Does the door open and close completely?

• Does the door stay closed and not reverse unintentionally when fully closed?

If your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails (see page 26).

Adjustment procedures are outlined below. Run the

opener through a complete travel cycle after each adjustment.

Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Simply wait 15 minutes and try again.

Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit adjustments.

How and When to Adjust the Limits

• If the door does not

open completely

but opens

at least

five feet:

Increase

travel. Turn the UP limit adjustment

screw clockwise. One turn equals 2" of travel.

NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4"between the trolley and the bolt.

• If door does not open at least 5 feet:

Adjust the UP (open) force as explained in Adjustment Step 2.

• If the door does not

close completely:

Increase

down

travel. Turn the DOWN limit adjustment screw counterclockwise. One turn equals 2" of travel.

If door still won't close completely and the trolley bumps into the pulley bracket (see page 4 or 5), try lengthening the door arm. (See page 22.)

If you have adjusted the door arm to the maximum length and the door still will not close completely, lower the header bracket. See Installation Step 1, pages 8 and 9.

• If the opener

reverses

in fully closed position:

Decrease

down

travel. Turn the DOWN limit adjustment

screw clockwise. One turn equals 2" of travel.

• If the door

reverses

when closing and

there is no visible interference to travel cycle:

If the opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or obstructed. See Troubleshooting, page 19.

Test the door for binding: Pull the manual release handle. Manually open and close the door. If the door is binding, call for garage door service. If the door is not binding or unbalanced, adjust the DOWN (close) force. See Adjustment Step 2.

Adjustment Section: Pages 24 – 26

Improper adjustment of the travel limits will interfere with the proper operation of the safety reverse system.

The door might not reverse properly when required and could seriously injure or kill someone under it.

Test the safety reverse system following all adjustments to the travel limits. See page 26.

Adjustment Step 2

Adjust the Force

Too much force on the door will interfere with the proper operation of the safety reverse system.

The door might not reverse properly when required and could seriously injure or kill someone under it.

Do not increase the force beyond the minimum amount required to close the door. Do not use the force adjustments to compensate for a binding or sticking garage door. Test the safety reverse system following all adjustments to force levels. See page 26.

Force adjustment controls are located on the right panel of the opener. Force adjustment settings regulate the amount of power required to open and close the door.

The door will

stop

in the updirection if anything

interferes with its travel. The door will

reverse

in the

down

direction if anything interferes with its travel

(including binding or unbalanced doors). If the forces are set too light, door travel may be

interrupted by

nuisance reversals

in the

down

direction and

stops

in the

direction. Weather conditions can affect the door movement, so occasional adjustment may be needed.

The maximum force adjustment range is 260 degrees, about 3/4 of a complete turn. Do not force controls beyond that point. Turn force adjustment controls with a screwdriver.

How and When to Adjust the Forces

Test the DOWN (close) force

Grasp the door bottom when the door is about halfway through DOWN (close) travel. The door should reverse.

Reversal halfway through down travel does not guarantee reversal on a one inch obstruction. See page 26.

If the door is hard to hold or doesn't reverse, decrease the DOWN (close) force by turning the control counterclockwise.

Make 10 degree turn adjustments until the door reverses normally. After each adjustment, run the opener through a complete cycle.

Test the UP (open) force

Grasp the door bottom when the door is about halfway through UP (open) travel. The door should stop. If the door is hard to hold or doesn't stop, decrease UP (open) force by turning the control counterclockwise.

Make 10 degree turn adjustments until the door stops easily. After each adjustment, run the opener through a complete travel cycle.

If the door doesn't open

at least

5 feet

Increase UP (Open) force by turning the control clockwise. Make 10 degree turn adjustments until door opens completely. Re-adjust the UP limit if necessary. After each adjustment, run the opener through a complete travel cycle.

If the door

reverses

during the down (close) cycle

and the opener lights aren't flashing

Increase DOWN (close) force by turning the control clockwise. Make 10 degree turn adjustments until the door completes a close cycle. After each adjustment, run the opener through a complete travel cycle. Do

not increase the force beyond the minimum amount required to close the door.

WARNING

Page 26

Adjustment Step 4

Test the Safety Reverse System

Test

• With the door fully open, place a one-inch board

(or a 2x4 laid flat) on the floor, centered under the garage door.

• Operate the door in the down direction.

The door

must reverse on striking the obstruction.

Adjustment

If the door

stops

on the obstruction, it is not traveling

far enough in the down direction.

• Increase the DOWN limit by turning the DOWN

limit adjustment screw counterclockwise 1/4 turn.

• Repeat the test.

On a sectional door, make sure limit adjustments do not force the door arm beyond a straight up and down position. See the illustration on page 22.

• When the door reverses on the one-inch board,

remove the obstruction and run the opener through 3 or 4 complete travel cycles to test adjustment.

If the door will not reverse on the 2x4 after repeated adjustment attempts, call for professional garage door service.

Failure to test and adjust the safety reverse system may result in serious injury or death to persons trapped by a closing garage door.

Repeat this test once a month and adjust as needed.

Adjustment Step 3

Test The Protector®System

• Press the remote control push button to open the door.

• Place the opener carton in the path of the door.

• Press the remote control push button to close the door.

The door will not move more than an inch,

and the opener lights will flash.

Professional service is required if the opener closes the door when the safety reversing sensor is obstructed.

The garage door opener will not close from a remote if the indicator light in either sensor is off (alerting you to the fact that the sensor is misaligned or obstructed).

The garage door can be closed by pressing and

holding

the Door Control push bar until down travel

is completed.

Without a properly working safety reversing sensor, persons (particularly children) could be seriously injured or killed if trapped by a closing garage door.

Repeat this test once a month.

Having a Problem?

Situation Probable Cause & Solution

The opener doesn't operate from either the door control or the remote control:

Opener operates from remote control, but not from door control:

The door operates from the door control, but not from the remote control:

The remote control has short range:

The garage door opens and closes by itself:

The door doesn't open completely:

The door stops but doesn't close completely:

Opener noise is disturbing in living quarters of home:

1. Does the opener have electric 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.)

2. Have you disabled all door locks? Review installation instruction warnings on Page 7.

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

4. The garage door spring may be broken. Have it replaced.

5. Repeated operation may have tripped the overload protector in the motor. Wait 15 minutes. Try again.

1. Is the door control push bar lit? If not, Remove the bell wire from the opener terminal screws. Short the red and white terminals by touching both terminals at the same time with a piece of wire. If the opener runs, check for a faulty wire connection at the door control, a short under the staples, or a broken wire.

2. Are the wiring connections correct? Review Step 6, page 14.

1. Is the door push bar flashing? If your model has the Lock feature, turn it

off.

2. Your opener needs to re-learn a remote control code. Refer to instructions on the opener panel.

3. Program the receiver to match the remote control code.

4. Repeat the receiver programming procedure with all remote controls.

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

2. Remove the bell wire from the door control terminals and operate from the remote control only. If this solves the problem, the door control is faulty (replace), or there is an intermittent short on the wire between the door control and the opener.

3. Clear memory and reprogram all remote controls.

1. If the door has been working properly but now doesn't open all the way, increase the

up force.

See page 25.

2. Is something obstructing the door? Remove the obstruction or repair the door.

3. If door opens at least 5 feet, the travel limits may need to be increased. One turn equals 2 inches of travel. See page 24.

Repeat the safety reverse test after the adjustment is complete.

Review the travel limits adjustment procedures on page 24.

Repeat the safety reverse test after any adjustment of door arm length, close force or down limit.

1. Change the location of the remote control in your car.

2. Check to be sure the antenna on the side or back panel of the opener extends fully downward.

3. Some installations may have shorter range due to a metal door, foil backed

insulation, or metal garage siding.

If operational noise is a problem because of proximity of the opener to the living quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to minimize vibration to the house and is easy to install.

Having a Problem?

(continued)

Situation Probable Cause & Solution

The door reverses for no apparent reason and opener lights don't blink:

The door reverses for no apparent reason and opener lights blink for 5 seconds after reversing:

The opener lights …

The opener strains or maximum force is needed to operate door:

The opener motor hums briefly, then won't work:

1. The garage door springs are broken. See above.

2. If the problem occurs on the first operation of the opener, door may be locked.

Disable

the door lock

. If the belt was removed and reinstalled, the motor may be out of phase. Remove the belt; cycle the motor to the down position. Observe the drive sprocket. When it turns in a clockwise direction and stops in the down position, reinstall the belt.

Repeat the safety reverse test after the adjustment is complete.

The opener won't operate due to power failure:

The door opens but won't close:

Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See page 19.

1. Is something obstructing the door? Pull the manual release handle. Operate the door manually. If it is unbalanced or binding, call for professional garage door service.

2. Clear any ice or snow from the garage floor area where the door closes.

3. Review the force adjustment procedures on page 25.

4. If door reverses in the

fully closed

position, decrease the travel limits (page 24).

Repeat the safety reverse test after adjustments to force or travel limits. The need for occasional adjustment of the force and limit settings is normal. Weather conditions in particular can affect door travel.

don't turn on:

Replace the light bulbs (75 watts maximum). Use a

standard neck

garage door opener

bulb if regular bulb burns out.

don't turn off:

Is the Light feature on? Turn it

off.

The door may be out of balance or the springs are broken. Close the door and use the manual release handle to disconnect the trolley. 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 opener and call for professional garage door service.

Do not increase the force to operate the opener.

1. Use the manual release handle to disconnect the trolley. The door can be opened and closed manually. When power is restored, press the Door Control push bar and trolley will automatically reconnect (unless trolley is in lockout position.) See page 28.

2. The Outside Quick Release accessory (for use on garages with no service door) disconnects the trolley from outside the garage in case of power failure.

1. If the opener lights blink, check the safety reversing sensor. See page 19.

2. If the opener lights do not blink and it is a new installation, check the down force. See Adjustment Step 2, page 25. For an existing installation, see below.

Repeat the safety reverse test after the adjustment is complete.
