Preparing your garage door

WARNING

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.

• 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.

• 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:

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.

CAUTION

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.

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 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.

• Installation Step 10 – Alternate floor mounting of

the safety reversing sensor will require hardware

not provided.

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

rail extension kits listed on Accessories page.

ASSEMBLY STEP 1

CAUTION

Assemble the Rail & Install the Trolley

To prevent INJURY from pinching, keep hands and

fingers away from the joints while assembling the rail.

To avoid installation difficulties, do not run the

garage door opener until instructed to do so.

The front rail has a cut out “window” at the door end

(see illustration). The hole above this window is

larger on the top of the rail than on the bottom. A

smaller hole 3-1/2" (8.9 cm) away is close to the rail

edge. Rotate the back rail so it has a similar hole

close to the opposite edge, about 4-3/4" (12 cm)

from the far end. NOTE: Using the sequence above

the clips will be facing down.

NOTE: Rail sections may be assembled with the

clips up or down (down is preferred) disassembly of

rail may damage clips.

3. Place the motor unit on packing material to protect

the cover, and rest the back end of the rail on top.

For convenience, put a support under the front

end of the rail.

4. As a temporary trolley stop, clamp locking pliers

onto the rail 8" (20 cm) from the center of the idler

pulley hole, as shown.

1. Remove the straight door arm and hanging

bracket packaged inside the front rail and set

aside for Installation Step 5 and 12. NOTE: To

prevent INJURY while unpacking the rail carefully

remove the straight door arm stored within the rail

section.

5. Check to be sure there are 4 plastic wear pads

inside the inner trolley. If they became loose

during shipping, check all packing material. Snap

them back into position as shown.

2. Align the rail sections on a flat surface as shown

and slide the tapered ends into the larger ones.

Tabs along the side will lock into place.

6. Slide the trolley assembly along the rail from the

back end to the locked pliers.

WARNING

Electrical Requirements

To prevent possible SERIOUS INJURY or DEATH from

electrocution or fire:

To avoid installation difficulties, do not run the

opener at this time.

• 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.

INSTALLATION STEP 10

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.

IMPORTANT INFORMATION ABOUT

THE SAFETY REVERSING SENSOR

– Install the safety reversing sensor so beam is NO

HIGHER than 6" (15 cm) above garage floor.

When properly connected and aligned, the 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 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.

MOUNTING AND WIRING THE SAFETY SENSORS

Figure 5

• 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 (Figure 5).

Wing Nut

Carriage Bolt

1/4"-20x1/2"

• Finger tighten the wing nuts.

Lens

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

insulated staples to secure wire to wall and ceiling.

TROUBLESHOOTING THE SAFETY SENSORS

• Strip 7/16" (11 mm) of insulation from each set of

wires. Separate white and white/black wires

sufficiently to connect to the opener quick-connect

terminals. Twist like colored wires together. Insert

wires into quick-connect holes: white to white and

white/black to grey (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 opener connections.

• Incorrect wiring between sensors and opener.

• A broken wire.

ALIGNING THE SAFETY 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.

2. If the sending eye indicator light glows steadily but

the receiving eye indicator light doesn't:

• Check alignment.

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.

• 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 blink 10 times. See page 20.

• 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.

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.

ADJUSTMENT STEP 1

WARNING

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.

Adjust the UP and DOWN Travel

Limits

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.

• Does the door open and close completely?

• 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.

• 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 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.

Cover Protection Bolt

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 five 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.

NOTE: To prevent the trolley from hitting the cover

protection bolt, keep a minimum distance of 2-4"

(5 cm - 10 cm) between the trolley and the bolt.

ADJUSTMENT LABEL

• 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 reverses when closing and there is

no visible interference to travel cycle:

• If the door does not close completely:

Increase down travel. Turn the down limit

adjustment screw counterclockwise. One turn

equals 2" (5 cm) of travel.

If the opener lights are flashing, the Safety

Reversing Sensors are either not installed,

misaligned, or obstructed. See Troubleshooting,

page 22.

If door still won't close completely and the trolley

bumps into the pulley bracket (page 4), 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.

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

Force adjustment controls are located on the right

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.

• 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.

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

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, 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.

Right Panel

Antenna

• 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.

FORCE ADJUSTMENT LABEL

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.

Open Force

Close Force

• 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

WARNING

Test the Safety Reversal System

Without a properly installed safety reversal system,

persons (particularly small children) could be

SERIOUSLY INJURED or KILLED by a closing garage

door.

TEST

• 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.

• Safety reversal system MUST be tested every month.

• 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 the floor.

• 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 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.

1-1/2" (3.8 cm) board

(or a 2x4 laid flat)

• Any repair to or adjustment of the garage door

(including springs and hardware).

• 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 door will not move more than an inch

(2.5 cm), 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.
