The Protector System

Information you'll need before you begin the installation of 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.

Installation procedures are the same for sectional and one-piece doors.

Be sure power to the opener is disconnected.

The sending eye transmits an invisible light beam to the receiving eye. The units can be installed on either side of the garage door as long as the sun never shines directly into the receiving eye lens.

Look at the label on the connector end of each case to identify the sensors.

The brackets must be connected and fastened so that the sending and receiving eyes face each other as shown.

If an obstruction breaks the light beam while the garage door is closing, the door will stop and reverse to full open position and the opener lights will flash for 5 seconds.

The brackets must be securely fastened to a solid surface such as the studs on either side of the door, or add a piece of wood at each location if installing in masonry construction.

WARNING

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

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.

The invisible light beam path must be unobstructed. No part of the garage door (or door tracks, springs, hinges, rollers or other hardware) can interrupt the beam while the door is closing. If it does, use a piece of wood to build out each sensor mounting location to the minimum depth required for light beam clearance.

Installation Step 4

Install the Safety Reversing Sensor (Receiving and Sending Eyes)

Figures 1 and 2 show assembly of brackets and "C" wrap based on the recommended installation of the sensors on each side of the garage door as shown on page 16.

However, Figures 3 and 4 are variations which may fit your installation requirements better. Make sure the

wraps and brackets are aligned so the sensors will face each other across the garage door.

1. Fasten the "C" wraps to the mounting brackets having square holes, using the hardware shown in Figure 3.

2. Connect each assembly to a slotted bracket, using the hardware shown in Figure 2.

Note the alignment of the brackets for left and right sides of the door.

3. Finger tighten the lock nuts.

4. Use bracket mounting holes as a template to locate and drill (2) 3/16" diameter pilot holes on both sides of the garage door, 4"-6" above the floor but not exceeding 6". (See warning on page 16.)

5. Attach bracket assemblies with 1/4"x1-1/2" lag screws as shown in Figure 2.

6. Adjust right and left side bracket assemblies to the same distance out from the mounting surface. Make sure all door hardware obstructions are cleared. Tighten the nuts securely.

Install the Door Control and Connect all Wiring

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.

1. Strip 1/4" of insulation from one end of the bell wire and connect it to the two screw terminals on the back of the door control by color: white to 2 and white/red to 1 (see Figure 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. Be careful not to pierce the wire with a staple, creating a short. If your access door is near the

garage door, you may run this wire with the Safety Reversing Sensor wires along the top of the rail. See page 18.

4. Remove the Control Center door on the right panel of the opener to access the terminal screws.

5. Thread all wires through the opening at the base of the drive shaft cover (see Figure 2).

6. Insert the remaining wire through the hole in the power unit and strip 1/4" of insulation from each set of wires.

7. Connect the door control wire to the opener terminal screws: white to 2 and white/red to 1. (See Figure 3.)

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

9. 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.

Installation Step 8

Electrical Requirements

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.

To avoid installation difficulties,

do not run the opener until Step 9 below.

WARNING

To prevent electrocution or fire, installation and wiring must be in compliance with local electrical and building codes.

Do NOT use an extension cord, 2-wire adapter, or change the plug in any way to make it fit your outlet.

If permanent wiring is required by your local code, refer to the following procedure:

WARNING

To prevent electrocution

garage door opener use for the permanent connection.

To make a permanent connection through the 7/8" diam. hole in the top of the opener (according to local code):

• Remove the opener cov er screws and set the cover aside.

• Remove the attached 3-prong cord.

• Connect the black (line) wire to the screw on the brass terminal; the white (neutral) wire to the screw on the silver terminal; and the ground wire to the green ground screw. The opener must be grounded.

Installation Step 9

Complete Safety Reversing Sensor Installation

Aligning the Safety Sensors

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

sending and receiving eyes will glow steadily if wiring connections and alignment are correct.

The sending eye indicator light will glow regardless of alignment or obstruction. If the indicator light is off, dim, or flickering in the receiving eye (and the invisible light beam path is not obstructed), alignment is required.

• Loosen the sending eye wing nut and re-adjust, aiming

directly at the receiving eye. Lock in place.

• Loosen the receiving eye wing nut and adjust sensor

vertically and/or horizontally until it receives the sender’s beam. When the green indicator light glows steadily, tighten the wing nut.

Trouble Shooting

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 under staples or at screw terminal connections.

• Incorrect wiring between sensors and opener.

• An open wire (wire break).

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 opener lights will flash 10 times. (If bulbs are not installed, 10 clicks are audible.) See page 16.

Page 23

Installation Step 10

Install the Lights and Lens

• Install a 100 watt maximum light bulb in each socket. The lights will turn ON and remain lit for approximately 4-1/2 minutes when power is connected. Then the lights will turn OFF.

• Insert bottom lens tabs into slots on chassis and tilt towards chassis to engage top tabs, then drop down gently into place. (See illustration.)

• To remove, lift lens up and gently tilt slightly outward and down, then pull out to clear bulbs. Use care to

avoid snapping off bottom lens tabs.

• If the bulbs burn out prematurely, replace with standard neck Garage Door Opener bulbs. (Fluorescent bulbs are

not recommended because of possible interference with receiver/transmitter signals.)

Fasten Door Bracket

Follow instructions which apply to your door type as illustrated below or on page 25.

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.

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.

in the illustration, decrease the UP limit until the door is parallel to the floor.

Page 28

Adjustment Section: Pages 28 – 30

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 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 30).

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.

WARNING

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

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

How and When to Adjust the Limits

If the door does not open completely but opens at least five feet:

Increase up travel. Turn the UP limit adjustment screw clockwise. One turn equals 2" of travel.

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, try lengthening the door arm. (Page 26.)

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 12 and 13.

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 22.

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.

Page 29

Adjustment Step 2

Adjust the Force

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. Turn force adjustment controls with a screwdriver.

WARNING

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

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 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.

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.

3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in sight until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.

4. Check safety reversal system monthly. See page 30. The garage door MUST reverse on contact with a one inch object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to one of the controls (either force or limits of travel), the other control may need to be adjusted also, and the safety reversal system must be checked. Failure to properly adjust the opener may result in severe injury or death.

5. If possible, use the manual release only when the door is in a closed position. Caution should be taken whenever the disconnect cord is actuated with the door open. Weak or broken springs may cause the door to

fall rapidly, causing injury or death to persons.

6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not reverse when required, and could result in severe injury or death. Repairs to cables, spring assemblies and

other hardware must be made by a professional garage door person.

7. Disconnect the electric power to the garage door opener before making any repairs or removing the covers.

Force and Limit Adjustment Controls

FORCE CONTROLS

LIMIT CONTROLS

Weather conditions may cause some minor changes in door operation requiring some re-adjustments, particularly during the first year of operation.

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.

Maintenance Schedule

Once a Month

Manually operate door. If it is unbalanced or binding, call for professional garage door service.

Check to be sure door opens & closes fully. Adjust limits and/or force if necessary. (See pages 28 & 29.)

The Remote Control Transmitter

The opener must learn the code of any new remote control. Page 33 explains how to program your receiver and how to erase all codes if required. Self service of your receiver and remote controls is not recommended. If service is needed, call the toll-free number listed on the back page.

The Transmitter Battery

The green test light will glow and the opener will operate when the remote control is activated, as long as there is adequate battery power.

If the power indicator light is dim or off, replace the battery. Also check the test light if transmission range decreases.

The 12 volt battery should produce power for at least a year.

Dispose of your old battery properly.

Repeat the safety reverse test. Make any necessary

adjustments (See page 30).

Once a Year

Oil door rollers, bearings and hinges. The opener does not require additional lubrication. Do not grease the door tracks.

Page 32

Operation of Your Opener

Activate the opener with any of the following:

• The Remote Control Transmitter. Hold push button

down until the door starts to move.

• The Door Control. Hold push bar or button down

until the door starts to move.

• The Outside Keylock or Keyless Entry. (See

Accessories)

When the opener is activated with the safety reversing sensor installed and correctly aligned:

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

2. If closing, the door will reverse.

3. If opening, the door will stop (allowing space for entry and exit of pets and for fresh air).

4. If the door has been stopped in a partially open position, it will close.

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

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

7. The garage door will reverse in the closing cycle when the invisible beam is broken. 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 not aligned correctly, the door won't close from any remote transmitter. You can close the door with the Door Control, the Outside Keylock, or Keyless Entry, however, if you activate them until down travel is complete. If you release them too soon, the door will reverse.

The opener lights will blink for 5 seconds when the safety reversing sensor causes the door to reverse.

Opener Lights will turn on under the following conditions: When the opener is initially plugged in; when the power is interrupted; when the opener is activated. They will turn off automatically after 4-1/2 minutes or provide constant light when the Light feature is activated. Bulb size is 100 watts maximum.

WARNING

Weak or broken springs could allow an open door to fall (either rapidly or unexpectedly), resulting in serious injury, death or property damage.

Receiver & Remote Control Programming

NOTICE: To comply with FCC rules, adjustment or modification of this receiver and/or transmitter are prohibited, except for changing the code setting or replacing the transmitter battery. THERE ARE NO OTHER USER SERVICEABLE PARTS.

Your garage door opener receiver and remote control transmitter have been set at the factory to a matching code. The door will activate when the remote control push button is pressed.

Your "Smart" garage door opener will operate with:

• up to four "Smart" remote control transmitters (with green indicator lights),

• a Keyless Entry System, and

• code switch remote controls with red indicator lights.

Below are instructions for programming your opener to match any additional remotes you may purchase. See available accessories on page 38.

To add a single function remote control:

1. Press and hold the remote push button, see Figure 1.

2. Then press and release the "Smart" (learn) button on the right side panel of the opener, Figure 2. The opener lights will flash once.

3. Release the remote push button.

Now the opener will operate when the remote control push button is pressed.

If you release the remote control push button before the opener lights flash, the opener will not accept the code.

To change the selected push button on the same remote:

If you decide to use a different remote control button than originally programmed into the opener, you need to erase all the learned codes and reprogram each remote used to operate the garage door opener.

To erase all remote control codes:

• Press and hold the "Smart" button on the opener panel

until the indicator light turns off (about 6 seconds). All

the codes the opener has learned will be erased.

• To reprogram, repeat Steps 1 – 3 for each remote control in use.

Code programming instructions are also located on the opener panel.

To Add the Keyless Entry

We recommend that you program your code before you install the Keyless Entry. You will not need assistance, and you can test the reception at the mounting location before installation.

1. Choose a 4-digit code using numbers from 0 to 9. You can use a number more than once (for example, 4, 0, 4, 1). Press the selected code digits on the keypad.

2. Press and hold the Enter button while you press the “SRT” (learn) button on the opener panel. The indicator light will blink and the door will begin to move.

3. Release the Enter button. Now the opener has learned the selected keypad code.

To ensure that your portable remote control codes were not disturbed while you were programming the Keyless Entry, test your remotes and reprogram them if necessary.

To change the code at any time, repeat steps 1-3.

Having a Problem?

Situation Probable Cause & Solution

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

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

The door operates from the door control, but not from 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 w all switch.)

2. Have you disabled all door locks? Review installation instruction warnings on Page 11.

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 Installation Step 7, page 21.

1. If your model has the Lock feature, turn it off.

2. Is the wall push button flashing? Your opener needs to re-learn a remote control code. Refer to instructions on the opener panel.

3. Does the battery test light glow when the remote control push button is pressed? If not, replace the battery.

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

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

The remote control has short range:

Opener noise is disturbing in living quarters of home:

The garage door opens and closes by itself:

The door doesn't open completely:

1. Check the battery test light. If the light is dim, replace the battery.

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

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

4. 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.

1. Be sure that all remote control push buttons and battery indicator lights 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.

1. If the door has been working properly but now doesn't open all the way, increase the up force. See page 29.

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 28.

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 28.

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

Page 35

Having a Problem?

Situation Probable Cause & Solution

(continued)

The door opens but won't close:

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… don't turn on:

1. If the opener lights blink, check the safety reversing sensor. See page 22.

2. If the opener lights do not blink and it is a new installation, check the down force. See Adjustment Step 2, page 29. For an existing installation, see below.

Repeat the safety reverse test after the adjustment is complete.

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 29.

4. If door reverses in the fully closed position, decrease the travel limits (page 28).

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.

Check the safety reversing sensor. Remove any obstruction or align the receiving eye. See pages 12 and 22.

Replace the light bulb(s) (100 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 opener strains or maximum force is needed to operate door:

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

The opener won't operate due to power failure:

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. 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.

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 32.

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.
