The Protector System^®

IMPORTANT INFORMATION ABOUT THE

SAFETY REVERSING SENSOR

WARNING

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.

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.

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 opener light will flash for 5 seconds.

Disconnect power to the garage door opener before

installing the safety reversing sensor.

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, 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 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

garage door track without additional hardware.

Installation Step 8

Electrical Requirements

WARNING

To prevent electrocution or fire, installation and wiring

must be in compliance with local electrical and building

codes.

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.

Do NOT use an extension cord, 2-wire adapter, or change

the plug in any way to make it fit your outlet.

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

qualified electrician to install the proper outlet.

To avoid installation difficulties,

do not run the opener until Step 9 below.

If permanent wiring is required by your local code,

refer to the following procedure:

Installation Step 12

CAUTION

Fasten Door Bracket

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.

Follow instructions which apply to your door type

as illustrated below or on page 21.

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.

Adjustment Section: Pages 24 – 26

Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the safety

reversing sensors are completely installed.

WARNING

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 monthly, and following all adjustments to

the travel limits. See page 26.

Limit adjustment settings regulate the points at which the

door will stop when moving up or down.

The door will stop in the up direction if anything

interferes with door travel. The door will reverse in 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 or

button. 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).

LABEL

Repeated operation of the opener during adjustment

procedures may cause the motor to overheat and shut off.

Simply wait 15 minutes and try again.

Adjust DOWN Travel

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:

If the opener reverses in fully closed position:

Decrease down travel. Turn the DOWN limit adjustment

screw clockwise. One turn equals 2" of travel.

Increase up travel. Turn the UP 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 door does not open at least 5 feet: Adjust the UP

(open) force as explained in Adjustment Step 2.

If the opener lights are flashing, the Safety Reversing

Sensors are either not installed, misaligned, or obstructed.

See Troubleshooting, page 18.

If the door does not close completely:

Increase down travel. Turn the DOWN limit adjustment

screw counterclockwise. One turn equals 2" of travel.

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.

If door still won't close completely, try lengthening the

door arm. (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 8/9.

Adjustment Step 2

Adjust the Force

WARNING

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 monthly, and 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 up direction 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 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.

How and When to Adjust the Forces

Test the DOWN (close) force

If the door doesn't open at least 5 feet:

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.

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.

If the door reverses during the down (close) cycle and

the opener lights aren't flashing:

Make small adjustments until the door reverses normally.

After each adjustment, run the opener through a complete

cycle.

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.

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. After

each adjustment, run the opener through a complete

travel cycle.

Adjustment Step 4

Test the Safety Reverse System

WARNING

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.

Test

• 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

Having a Problem?

Situation

Probable Cause & Solution

The opener doesn't

operate from either

the door control or

the remote control:

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.

Opener operates from

the remote control, but

not from the door

control:

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 Installation Step 7, page 17.

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

the door control, but not

from the remote

control:

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.

The remote control has

short range:

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

2. Check to be sure the antenna on the right side panel of opener extends fully.

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

metal garage siding.

Opener noise is

disturbing in living

quarters of home:

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.

The garage door

opens and closes by

itself:

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.

The door doesn't open

completely:

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.

The door stops but

doesn't close

completely:

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.

Situation

Probable Cause & Solution

The door opens but

won't close:

1. If the opener lights blink, check the safety reversing sensor. See page 18.

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.

The door reverses for no

apparent reason and

opener lights don't

blink:

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.

The door reverses for no

apparent reason and

needed to operate door: 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.

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.

Repeat the safety reverse test after the adjustment is complete.

The opener won't

operate due to power

failure:

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.
