Do you have an access door in addition to the
garage door? If not, Model 1702 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.
• Installation Step 10 -Alternate floor mounting of
the safety reversing sensor will require hardware
not provided.

Requirements

To prevent possible SERIOUSINJURYor DEATHfrom
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 BEFOREremoving cover to
establish permanent wiring connection.
• Garagedoor installation and wiring MUST be in
compliance with all local electrical and building codes.
• NEVERuse 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.

System

• Be sure power is not connected to the garage door
opener BEFOREinstalling the safety reversing sensor.
• To prevent SERIOUSINJURYor DEATHfrom a closing
garage door:
- Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.

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

- Install the safety reversing sensor so beam is NO
HIGHERthan 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 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.

MOUNTING AND WIRING THE SAFETY SENSORS

Figure 5

• Slide a 1/4"-20xl/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).

Carriage Bolt
1/4"-20xl/2"

• Finger tighten the wing nuts.
• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.

TROUBLESHOOTING

• 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).

THE SAFETY SENSORS

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

• Loosen the sending eye wing nut and readjust,
aiming directly at the receiving eye. Lock in place.

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, # will not close.
The opener lights will blink 10 times. (If bulbs are not
installed, 10 clicks can be heard.) See page 21.

• 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.

To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.

Follow instructions which apply to your door type
as illustrated below or on the following page.
A horizontal reinforcement brace should be long
enough to be secured to two or three vertical
supports. A vertical reinforcement brace should
cover the height of the top panel.
Figure 1 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.
NOTE: Many door reinforcement kits provide for
direct attachment of the clevis pin and door arm. In
this case you will not need the door bracket; proceed
to Step 12.

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.
• 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

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?
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

If the opener lights are flashing, the Safety
Reversing Sensors are either not installed,
misaligned, or obstructed. See Troubleshooting,
page 23.

If door still won't close completely and the trolley
bumps into the pulley bracket (page 4), try
lengthening the door arm (page 26) 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

Force

Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLYINJUREDor 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.
• NEVERincreaseforce beyond minimum amount
required to close garage door.
• NEVERuse 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.

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
Force Adjustment

• 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 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.

i=l

• 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.

FORCEADJUSTMENTLABEL

• 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.

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" (3.8 cm) high 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 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).

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

Opener

Your Security-P R_
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.

Activate your opener with any of the following:
• The hand-held Remote Control: Hold the push
button down until the door starts to move.

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.

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.

• The wall-mounted Door Control'. Hold the push
button or bar down until the door starts to move.
• The Keyless Entry (See Accessories): If supplied
with your garage door opener, it must be
programmed before use. See Programming.

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.

When the opener is activated (with the safety
reversing sensor correctly installed and aligned)
1. If open, the door will close. If closed, it will open.

The light will also turn on when someone walks
through the open garage door.

2. If closing, the door will reverse.
3. If opening, the door will stop.

It will turn off automatically after 4-1/2 minutes. Bulb
size is 75 watts maximum.

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
LIMITCONTROLS
during the first year of operation. (Leftsidepanel)

• 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.

Pages 28 and 29 refer to the
limit and force adjustments.
Only a screwdriver is required.
Follow the instructions carefully.

Once a Month

• 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.
• Repeated operation may have tripped the
overload protector in the motor. Wait 15 minutes
and try again.

• Manually operate door. If it is unbalanced or
binding, call a trained door systems technician.

2. Opener operates from the remote, but not from
the Door Control:

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

• Is the door control lit? If not, remove the bell wire
from the motor unit terminals. Short the red and

• Is the door push bar flashing? If your model has
the Lock feature, make sure it is off.

THE REMOTE CONTROL BATTERY

• Program the opener to match the remote control
code. (Refer to instructions on the motor unit
panel.) Repeat with all remotes.
4. The remote control has short range:

To prevent possible SERIOUSINJURY or DEATH:
• NEVERallow small children near batteries.

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

• If battery is swallowed, immediately notify doctor.

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.

• Check to be sure the antenna on the side or back
panel of motor unit extends fully downward.

Batt_krYe(+)

• Some installations may have shorter range due to
a metal door, foil backed insulation, or metal
garage siding.
5. 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 89LM can be installed. This
kit was designed to minimize vibration to the house
and is easy to install.

Dispose of old battery properly.

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 a
standard neck garage door opener bulb if regular
bulb burns out.

• Clear memory and re-program all remote controls.

• Is the Light feature on? Turn it off.

• Is something obstructing the door? Is it out of
balance, or are the springs broken? Remove the
obstruction or repair the door.

14. The opener strains or maximum
needed to operate doon

• 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 is in good working order but now
doesn't open all the way, increase the up force.
See Adjustment Step 2.
• 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.

Repeat the safety reverse test after any adjustment
of door arm length, close force or down limit.
9. The door opens but won't close:

• If the problem occurs on the first operation of the
opener, door may be locked. Disable the door lock.

• 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:

• 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.

• 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.

17. The chain droops or sags:

• Clear any ice or snow from the garage floor area
where the door closes.

• 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
