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.

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

door? If not, Model 7702CB Emergency Key Release

is required. See Accessories page.

• 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.

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

the garage door. The header bracket must be securely

fastened to structural supports.

SECTIONAL DOOR INSTALLATIONS

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

panel door? If so, horizontal and vertical reinforcement

is required (Installation Step 12).

• Installation Step 4 – Depending upon garage

construction, extension brackets or wood blocks may

be needed to install sensors.

• 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 (1.2 m) to the left or right of the door

center. See Installation Steps 1 and 12.

• Installation Step 4 – Alternate floor mounting of the

safety reversing sensor will require hardware not

provided.

• Installation Step 6 – Do you have a finished ceiling in

your garage? If so, a support bracket and additional

fastening hardware may be required.

WARNING

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.

• 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 12.

• 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.

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

the gap.

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

additional mounting hardware for the door bracket

(Step 12).

INSTALLATION STEP 4

WARNING

Install The Protector System

Be sure power is not connected to the garage door opener

BEFORE installing 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.

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.

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.

WARNING

Electrical Requirements

To prevent possible SERIOUS INJURY or DEATH from

electrocution or fire:

To avoid installation difficulties, do not run the

opener until Step 11 below.

• 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 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.

TROUBLESHOOTING THE SAFETY

REVERSING SENSORS

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.

1. If the sending eye indicator light does not glow steadily

after installation, check for:

• Electric power to the opener.

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:

• A short in the white or white/black wires. These can

occur at staples, or at opener 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:

• Loosen the sending eye wing nut and readjust, aiming

directly at the receiving eye. Lock in place.

• Check alignment.

• Loosen the receiving eye wing nut and adjust the

sensor until it receives the sender’s beam. When the

green indicator light glows steadily, tighten the wing

nut.

• 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

opener lights will flash 10 times. (See page 15.)

• 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 27. Follow adjustment procedures

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

- Turn the UP limit adjustment screw

counter-clockwise 4 turns.

3. 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.

- 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.

• Closed door adjustment: decrease DOWN travel

limit

- Turn the DOWN limit adjustment screw clockwise

4 complete turns.

ADJUSTMENT STEP 1

WARNING

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.

Limit adjustment settings regulate the points at which the

door will stop when moving up or down.

• Incorrect adjustment of garage door travel limits will

interfere with proper operation of safety reversal system.

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

control may also need adjustment.

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?

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on contact

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

If your door passes both of these tests, no limit

adjustments are necessary unless the reversing test fails

(Adjustment Step 3, page 29).

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.

CAUTION

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.

HOW AND WHEN TO ADJUST THE LIMITS

• If the door does not open completely but opens at

least 5 feet (1.5 m):

Limit Adjustment Screws

Left Side Panel

Increase up travel. Turn the UP limit adjustment screw

clockwise. One turn equals 2" (5 cm) of travel.

• If door does not open at least 5 feet (1.5 m):

Adjust the UP (open) force as explained in Adjustment

Step 2.

• If the door does not close completely:

ADJUSTMENT LABEL

Increase down travel. Turn the down limit adjustment

screw counterclockwise. One turn equals 2" (5 cm) of

travel.

If door still won't close completely try lengthening the

door arm (page 25) and decreasing the down limit.

Test the door for binding: Pull the emergency release

handle. Manually open and close the door. If the door

is binding or unbalanced, call for a trained door

systems technician. If the door is balanced and not

binding, adjust the DOWN (close) force. See

Adjustment Step 2.

• If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit adjustment

screw clockwise. One turn equals 2" (5 cm) 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 22.

WARNING

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.

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.

• Too much force on garage door will interfere with proper

operation of safety reversal system.

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.

• 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" high (3.8 cm) object (or 2x4 laid flat) on floor.

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

Force

Adjustment

Controls

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" (3.8 cm)

obstruction. See Adjustment Step 3, page 29. If the

door is hard to hold or doesn't reverse,

Back Panel

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.

Antenna

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.

FORCE ADJUSTMENT LABEL

• If the door doesn’t open at least 5 feet (1.5 m),

INCREASE UP (open) force by turning the control

clockwise. Make small adjustments until door opens

completely. Readjust the UP limit if necessary. After

each adjustment, run the opener through a complete

travel cycle.

ADJUSTMENT STEP 3

Test the Safety Reversal System

TEST

• Safety reversal system MUST be tested every month.

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

control may also need adjustment.

• 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.

• After ANY adjustments are made, the safety reversal

system MUST be tested. Door MUST reverse on contact

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

floor.

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

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 25.

• 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.

• If the unit continues to fail the Safety Reverse Test, call

for a trained door systems technician.

IMPORTANT SAFETY CHECK:

Test the Safety Reverse System 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.

WARNING

Without a properly installed safety reversing sensor, persons

(particularly small children) could be SERIOUSLY INJURED

or KILLED by a closing garage door.

ADJUSTMENT STEP 4

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 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.
