Preparing your garage door

Before you begin:

To prevent possible SERIOUS INJURY OR DEATH:

• Disable locks.

• ALWAYS call a trained door systems technician if garage

door binds, sticks, or is out of balance. An unbalanced

garage door may not reverse when required.

• Remove any ropes connected to garage door.

• Complete the following test to make sure your

garage door is balanced and is not sticking or binding:

• NEVER try to loosen, move or adjust garage door, door

springs, cables, pulleys, brackets or their hardware, all of

which are under EXTREME tension.

• Disable ALL locks and remove ALL ropes connected to

garage door BEFORE installing and operating garage door

opener to avoid entanglement.

1. Lift the door about halfway as shown. Release the

door. If balanced, it should stay in place, supported

entirely by its springs.

2. Raise and lower the door to see if there is any

binding or sticking.

If your door binds, sticks, or is out of balance, call a

trained door systems technician.

To prevent damage to garage door and opener:

• ALWAYS disable locks BEFORE installing and operating the

opener.

• ONLY operate garage door opener at 120V, 60 Hz to avoid

malfunction and damage.

• Do you have an access door in addition to the garage

door? If not, Model 1702LM Outside Quick Release is

required. See Accessories page.

Planning

Identify the type and height of your garage door. Survey

your garage area to see if any of the conditions below

apply to your installation. Additional materials may be

required. You may find it helpful to refer back to this page

and the accompanying illustrations as you proceed with

the installation of your opener.

• Look at the garage door where it meets the floor. Any

gap between the floor and the bottom of the door must

not exceed 1/4" (6 mm). Otherwise, the safety reversal

system may not work properly. See Adjustment Step 3.

Floor or door should be repaired.

Depending on your requirements, there are several

installation steps which may call for materials or

hardware not included in the carton.

SECTIONAL DOOR INSTALLATIONS

• Installation Step 1 – Look at the wall or ceiling above

the garage door. The header bracket must be securely

fastened to structural supports.

• Do you have a steel, aluminum, fiberglass or glass

panel door? If so, horizontal and vertical reinforcement

is required (Installation Step 11).

• Installation Step 5 – Do you have a finished ceiling in

your garage? If so, a support bracket and additional

fastening hardware may be required.

• The opener should be installed above the center of the

door. If there is a torsion spring or center bearing plate

in the way of the header bracket, it may be installed

within 4 feet (1.22 m) to the left or right of the door

center. See Installation Steps 1 and 11.

• Installation Step 10 – Depending upon garage

construction, extension brackets or wood blocks may

be needed to install sensors.

• If your door is more than 7 feet (2.13 m) high, see rail

extension kits listed on Accessories page.

• Installation Step 10 – Alternate floor mounting of the

safety reversing sensor will require hardware not

provided.

ONE-PIECE DOOR INSTALLATIONS

Without a properly working safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED

or KILLED by a closing garage door.

• The gap between the bottom of the garage door and the

floor MUST NOT exceed 1/4" (6 mm). Otherwise, the safety

reversal system may not work properly.

• Generally, a one-piece door does not require

reinforcement. If your door is lightweight, refer to the

information relating to sectional doors in Installation

Step 11.

• Depending on your door’s construction, you may need

additional mounting hardware for the door bracket

(Step 11).

• The floor or the garage door MUST be repaired to eliminate

the gap.

INSTALLATION STEP 5

Hang the Opener

To avoid possible SERIOUS INJURY from a falling garage

door opener, fasten it SECURELY to structural supports of

the garage. Concrete anchors MUST be used if installing any

brackets into masonry.

Two representative installations are shown. Yours may

be different. Hanging brackets should be angled (Figure

INSTALLATION STEP 6

Install the Door Control

To prevent possible SERIOUS INJURY or DEATH from

electrocution:

• Be sure power is not connected BEFORE installing door

control.

• Connect ONLY to 24 VOLT low voltage wires.

To prevent possible SERIOUS INJURY or DEATH from a

closing garage door:

• Install door control within sight of garage door, out of reach

of children at a minimum height of 5 feet (1.5 m), and away

from all moving parts of door.

• NEVER permit children to operate or play with door control

push buttons or remote control transmitters.

Locate the door control within sight of the door at a

minimum height of 5 feet (1.5 m) where small children

cannot reach, and away from all moving parts of the door

and door hardware.

1. Strip 1/4" (6 mm) of insulation from one end of the bell

wire. Connect it to the two screw terminals on the back

of the door control by color: white wire to 2 and

white/red wire to 1.

2. Fasten the Lighted Door Control Button securely with

6ABx1-1/2" screws. If installing into drywall, drill 5/32"

holes and use the anchors provided.

3. Run the bell wire up the wall and across the ceiling to

the opener. Use insulated staples to secure the wire in

several places. Do not pierce wire with a staple,

creating a short or open circuit.

Electrical Requirements

To prevent possible SERIOUS INJURY or DEATH from

electrocution or fire:

• Be sure power is not connected to the opener, and

disconnect power to circuit BEFORE removing cover to

establish permanent wiring connection.

• Garage door installation and wiring MUST be in compliance

with all local electrical and building codes.

• NEVER use an extension cord, 2-wire adapter, or change

plug in ANY way to make it fit outlet. Be sure the opener is

grounded.

To avoid installation difficulties, do not run the

opener at this time.

To reduce the risk of electric shock, your garage door

opener has a grounding type plug with a third grounding

pin. This plug will only fit into a grounding type outlet. If

the plug doesn't fit into the outlet you have, contact a

qualified electrician to install the proper outlet.

INSTALLATION STEP 10

Install The Protector System

Be sure power is not connected to the garage door opener

BEFORE installing the safety reversing sensor.

To prevent SERIOUS INJURY or DEATH from a closing

garage door:

• Correctly connect and align the safety reversing sensor.

This required safety device MUST NOT be disabled.

• Install the safety reversing sensor so beam is NO HIGHER

than 6" (15 cm) above garage floor.

The safety reversing sensor must be connected and

aligned correctly before the garage door opener will

move in the down direction.

IMPORTANT INFORMATION ABOUT

THE SAFETY REVERSING SENSOR

When properly connected and aligned, the sensor will

detect an obstacle in the path of its electronic beam. The

sending eye (with an amber 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 opener lights will flash

10 times.

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 units must be installed inside the garage 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 eye lens.

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.

The mounting brackets are designed to clip onto the

track of sectional garage doors without additional

hardware.

TROUBLESHOOTING THE SAFETY

REVERSING SENSORS

• Strip 1/4" (6 mm) 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 (Figure 6).

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 terminal connections.

ALIGNING THE SAFETY REVERSING SENSORS

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

sending and receiving eyes will glow steadily if wiring

connections and alignment are correct.

• 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:

The sending eye amber 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.

• Check alignment.

• Check for an open wire to the receiving eye.

• Loosen the sending eye wing nut and readjust, aiming

directly at the receiving eye. Lock in place.

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

sensor.

• 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.

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

opener lights will blink 10 times. (If bulbs are not

installed, 10 clicks can be heard.) See page 21.

below.

- 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" (5 cm) of trolley travel.

• Open door adjustment: decrease UP

travel limit

3. Connect the door arm to the trolley:

- Turn the UP limit adjustment screw counter-

clockwise 5-1/2 turns.

• 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.

- Press the Door Control push button. 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" (5 cm) of trolley travel.

• 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.

NOTE: When setting the up limit on the following page,

the door should not have a "backward" slant when fully

open as illustrated below. A slight backward slant will

cause unnecessary bucking and/or jerking operation as

the door is being opened or closed from the fully open

position.

ADJUSTMENT STEP 1

Adjust the UP and DOWN Travel Limits

Without a properly installed safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED

or KILLED by a closing garage door.

• Incorrect adjustment of garage door travel limits will

interfere with proper operation of safety reversal system.

Limit adjustment settings regulate the points at which the

door will stop when moving up or down.

To operate the opener, press the Door Control push bar.

Run the opener through a complete travel cycle.

• If one control (force or travel limits) is adjusted, the other

control may also need adjustment.

• Does the door open and close completely?

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on contact

with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.

• 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

(Adjustment Step 3, page 30).

Adjustment procedures are outlined below. Read the

procedures carefully before proceeding to Adjustment

Step 2. Use a screwdriver to make limit adjustments.

Run the opener through a complete travel cycle after

each adjustment.

To prevent damage to vehicles, be sure fully open door

provides adequate clearance.

NOTE: Repeated operation of the opener during

adjustment procedures may cause the motor to overheat

and shut off. Simply wait 15 minutes and try again.

NOTE: If anything interferes with the door’s upward

travel, it will stop. If anything interferes with the door’s

downward travel (including binding or unbalanced doors),

it will reverse.

ADJUSTMENT STEP 2

Adjust the Force

Without a properly installed safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED

or KILLED by a closing garage door.

• Too much force on garage door will interfere with proper

operation of safety reversal system.

• NEVER increase force beyond minimum amount required to

close garage door.

• NEVER use force adjustments to compensate for a binding

or sticking garage door.

• If one control (force or travel limits) is adjusted, the other

control may also need adjustment.

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on contact

with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.

Force adjustment controls are located on the back panel

of the motor unit. Force adjustment settings regulate the

amount of power required to open and close the door.

If the forces are set too light, door travel may be

interrupted by nuisance reversals in the down direction

and stops in the up direction. Weather conditions can

affect the door movement, so occasional adjustment may

be needed.

The maximum force adjustment range is about 3/4 of

a complete turn. Do not force controls beyond that

point. Turn force adjustment controls with a screwdriver.

NOTE: If anything interferes with the door’s upward

travel, it will stop. If anything interferes with the door’s

downward travel (including binding or unbalanced doors),

it will reverse.

HOW AND WHEN TO ADJUST THE FORCES

1. 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 1-1/2"

Force Adjustment Controls

(3.8 cm) obstruction. See Adjustment Step 3, page 30.

If the door is hard to hold or doesn't reverse,

DECREASE the DOWN (close) force by turning

the control counterclockwise. Make small adjustments

until the door reverses normally. After each adjustment,

run the opener through a complete 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 small 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.

BACK PANEL

2. 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 small adjustments until the door

stops easily and opens fully. After each adjustment, run

the opener through a complete travel cycle.

• 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

garage door.

• Operate the door in the down direction. The door must

reverse on striking the obstruction.

ADJUST

• 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.

NOTE: 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 26.

• Repeat the test.

• When the door reverses on the 1-1/2" (3.8 cm) board,

remove the obstruction and run the opener through 3

or 4 complete travel cycles to test adjustment.

IMPORTANT SAFETY CHECK:

Repeat Adjustment Steps 1, 2 and 3 after:

• Each adjustment of door arm length, limits, or force

controls.

• Any repair to or adjustment of the garage door

(including springs and hardware).

1-1/2" (3.8 cm) board

(or a 2x4 laid flat)

• Any repair to or buckling of the garage floor.

• Any repair to or adjustment of the opener.

ADJUSTMENT STEP 4

Test the Protector System

Without a properly installed safety reversing sensor, persons

(particularly small children) could be SERIOUSLY INJURED

or KILLED by a closing garage door.

• 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.

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).

If the opener closes the door when the safety

reversing sensor is obstructed (and the sensors are

no more than 6" (15 cm) above the floor), call for a

trained door systems technician.

Using Your Garage Door Opener

Your Security✚^®opener and hand-held remote control

have been factory-set to a matching code which changes

with each use, randomly accessing over 100 billion new

codes. Your opener will operate with up to eight

Security✚^®remote controls and one Security✚^®Keyless

Entry System. If you purchase a new remote, or if you

wish to deactivate any remote, follow the instructions in

the Programming section.

5. If obstructed while closing, the door will reverse. If the

obstruction interrupts the sensor beam, the opener

lights will blink for five seconds.

6. If obstructed while opening, the door will stop.

7. If fully open, the door will not close when the beam is

broken. The sensor has no effect in the opening cycle.

If the sensor is not installed, or is misaligned, the door

won't close from a hand-held remote. However, you can

close the door with the Door Control, the Outside

Keylock, or Keyless Entry, if you activate them until down

travel is complete. If you release them too soon, the door

will reverse.

Activate your opener with any of the following:

• The hand-held Remote Control: Hold the push button

down until the door starts to move.

• The wall-mounted Door Control: Hold the push button

or bar down until the door starts to move.

The opener light will turn on under the following

conditions: when the opener is initially plugged in; when

power is restored after interruption; when the opener is

activated.

• The Keyless Entry (See Accessories): If supplied with

your garage door opener, it must be programmed

before use. See Programming.

When the opener is activated (with the safety

reversing sensor correctly installed and aligned)

The light will also turn on when someone walks through

the open garage door.

1. If open, the door will close. If closed, it will open.

2. If closing, the door will reverse.

It will turn off automatically after 4-1/2 minutes. Bulb size

is A19. Bulb power is 75 watts maximum.

3. If opening, the door will stop.

Care of Your Opener

Having a Problem?

1. The opener doesn't operate from either the Door

Control or the remote control:

LIMIT AND FORCE ADJUSTMENTS:

Weather conditions may cause some

minor changes in door operation

requiring some readjustments,

particularly during the first year of

operation.

• 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.)

• Have you disabled all door locks? Review installation

instruction warnings on page 11.

• Is there a build-up of ice or snow under the door? The

door may be frozen to the ground. Remove any

restriction.

• The garage door spring may be broken. Have it

replaced.

LIMIT CONTROLS

(Left side panel)

Pages 28 and 29 refer to the limit

and force adjustments. Only a

screwdriver is required. Follow the

instructions carefully.

Repeat the safety reverse test

(page 30) after any adjustment of

limits or force.

Open Force Close Force

FORCE CONTROLS

(Back panel)

• Repeated operation may have tripped the overload

protector in the motor. Wait 15 minutes and try again.

MAINTENANCE SCHEDULE

Once a Month

2. Opener operates from the remote, but not from the

Door Control:

• Manually operate door. If it is unbalanced or binding,

call a trained door systems technician.

• Is the door control lit? If not, remove the bell wire from

the motor unit terminals. 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.

• Check to be sure door opens & closes fully. Adjust limits

and/or force if necessary. (See pages 28 and 29.)

• Repeat the safety reverse test. Make any necessary

adjustments. (See page 30.)

Twice a Year

• Are the wiring connections correct? Review Installation

Step 6, page 18.

• Check chain tension. Disconnect trolley first. Adjust if

necessary (see page 11).

3. The door operates from the Door Control, but not

from the remote control:

Once a Year

• Oil door rollers, bearings and hinges. The opener does

not require additional lubrication. Do not grease the

door tracks.

• Is the door push bar flashing? If your model has the

Lock feature, make sure it is off.

• Program the opener to match the remote control code.

(Refer to instructions on the motor unit panel.) Repeat

with all remotes.

The Remote Control Battery

4. The remote control has short range:

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

To prevent possible SERIOUS INJURY or DEATH:

• NEVER allow small children near batteries.

• If battery is swallowed, immediately notify doctor.

To reduce risk of fire, explosion or chemical burn:

• Replace ONLY with 3V2032 coin batteries.

• Check to be sure the antenna on the side or back

panel of motor unit extends fully downward.

• Some installations may have shorter range due to a

metal door, foil backed insulation, or metal garage

siding.

• Do NOT recharge, disassemble, heat above 100°C (212°F)

or incinerate.

5. Opener noise is disturbing in living quarters of

home:

The lithium battery should

produce power for up to 5 years.

To replace battery, use the visor

clip or screwdriver blade to pry

open the case as shown. Insert

battery positive side up (+).

• If operational noise is a problem because of proximity

of the opener to the living quarters, the Vibration

Isolator Kit 89LM can be installed. This kit was

designed to minimize vibration to the house and is

easy to install.

Battery

positive

side up (+)

Dispose of old battery properly.

Replace ONLY with 3V2032 coin

11. The door reverses for no apparent reason

and opener lights blink for 5 seconds after

reversing:

Having a Problem? (Continued)

6. The garage door opens and closes by itself:

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

• Check the safety reversing sensor. Remove any

obstruction or align the receiving eye. See

Installation Step 10.

• Remove the bell wire from the door control terminals

and operate from the remote 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 motor unit.

12. The opener lights don't turn on:

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

A19 standard neck garage door opener bulb if

regular bulb burns out.

• Clear memory and re-program all remote controls.

7. The door doesn't open completely:

13. The opener lights don't turn off:

• Is something obstructing the door? Is it out of balance,

or are the springs broken? Remove the obstruction or

repair the door.

• Is the Light feature on? Turn it off.

14. The opener strains or maximum force is

needed to operate door:

• If the door is in good working order but now doesn't

open all the way, increase the up force. See

Adjustment Step 2.

• 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

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 a

trained door systems technician. Do not increase

the force to operate the opener.

• If the door opens at least 5 feet (1.5 m), the travel

limits may need to be increased. One turn equals 2" (5

cm) of travel. See Adjustment Step 1.

Repeat the safety reverse test after the adjustment is

complete.

8. The door stops but doesn't close completely:

15. The opener motor hums briefly, then won't

work:

• Review the travel limits adjustment procedures on

page 28.

• The garage door springs may be broken. See

above.

Repeat the safety reverse test after any adjustment

of door arm length, close force or down limit.

• If the problem occurs on the first operation of the

opener, door may be locked. Disable the door lock.

9. The door opens but won't close:

• If the opener lights blink, check the safety reversing

sensor. See Installation Step 10.

Repeat the safety reverse test after the adjustment is

complete.

• If the opener lights don’t blink and it is a new

installation, check the down force. See Adjustment

Step 2, page 29. For an existing installation, see

below.

16. The opener won't operate due to power

failure:

• Use the emergency 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 32.

Repeat the safety reverse test after the adjustment

is complete.

10. The door reverses for no apparent reason and

opener lights don’t blink:

• 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.

• 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.

• Clear any ice or snow from the garage floor area

where the door closes.

17. The chain droops or sags:

• It is normal for the chain to droop slightly in the

closed door position. Use the emergency release

rope and handle to disconnect the trolley. If the

chain returns to the normal height when the trolley

is disengaged, and the door reverses on a 2x4 laid

flat, no adjustments are needed. (See page 11.)

• Review Adjustment Step 2 on page 29.

• If door reverses in the fully closed position, decrease

the travel limits (Adjustment Step 1).

Repeat 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.
