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" 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.

• 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" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener quick-connect terminals: white
to white and white/black to black. See Figure 5.
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.
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 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 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, it will not close.
The opener lights will blink 10 times. (If bulbs are not
installed, 10 clicks can be heard.) See page 17.
• 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.

– Turn the UP limit adjustment screw counter-
clockwise 5-1/2 turns.
3. Connect the door arm to the trolley:
– Press the Door Control push bar. The trolley
will travel to the fully open position.
• 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.
– 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" 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

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.
ADJUSTMENT STEP 1
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 one-inch high object (or 2x4 laid flat) on
floor.
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (see Adjustment Step 3, page 26).
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.

ADJUSTMENT STEP 2
WARNING
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
Adjust the Force
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 one-inch high 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 one-inch
obstruction. See Adjustment Step 3, page 26.
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.

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 one-inch 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 one-inch 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 22.
• Repeat the test.
• When the door reverses on the one-inch board,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.

Having a Problem?
3. The door operates from the Door Control, but
not from the remote control:
1. The opener doesn't operate from either the
Door Control or the remote control:
• Is the door push bar flashing? If your model has
the Lock feature, make sure it is off.
• 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 7.
• 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:
• Change the location of the remote control in your
car.
• 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.
• Check to be sure the antenna on the side or back
panel of motor unit extends fully downward.
• 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:
2. Opener operates from the remote, but not from
the Door Control:
• 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.
• Is the door control lit? If not, reverse the wires. If
the opener runs, check for a faulty wire connection
at the door control, a short under the staples, or a
broken wire.
• Are the wiring connections correct? Review
Installation Step 6, page 14.

11. The door reverses for no apparent reason and
opener lights blink for 5 seconds after
reversing:
Having a Problem? (Continued)
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 (100 watts maximum). Use
a standard neck garage door opener bulb if regular
bulb burns out.
• Clear memory and re-program all remote controls.
13. The opener lights don't turn off:
7. The door doesn't open completely:
• 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 force is
needed to operate door:
• 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, the travel limits
may need to be increased. One turn equals 2
inches of travel. See Adjustment Step 1.
Repeat the safety reverse test after the adjustment is
complete.
8. The door stops but doesn't close completely:
15. The opener motor hums briefly, then won't
work:
• Review the travel limits adjustment procedures on
page 24.
• The garage door springs may be broken. See
above.
Repeat the safety reverse test after any adjustment
of door arm length, close force or down limit.
• If the problem occurs on the first operation of the
opener, door may be locked. Disable the door lock.
9. The door opens but won't close:
Repeat the safety reverse test after the adjustment is
complete.
• If the opener lights blink, check the safety
reversing sensor. See Installation Step 10.
16. The opener won't operate due to power
failure:
• If the opener lights don’t blink and it is a new
installation, check the down force. See Adjustment
Step 2, page 25. For an existing installation, see
below.
• 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 28.
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
• 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 7.)
where the door closes.
• Review Adjustment Step 2 on page 25.
• 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.
