Install the Door Control
To prevent possible SERIOUS INJURY or DEATH from
electrocution:
• Be sure power is not connected BEFORE installing door
control.
• Connect ONLY to 24 VOLT low voltage wires.
To prevent possible SERIOUS INJURY or DEATH from a
closing garage door:
• Install door control within sight of garage door, out of
reach of children at a minimum height of 5 feet, and
away from all moving parts of door.
• NEVER permit children to operate or play with door
control push buttons or remote control transmitters.
• Activate door ONLY when it can be seen clearly, is
properly adjusted, and there are no obstructions to door
travel.
• ALWAYS keep garage door in sight until completely
closed. NEVER permit anyone to cross path of closing
garage door.
Locate door control within sight of the door at a
minimum height of 5 feet where small children cannot
reach, and away from moving parts of the door and
door hardware. The installation surface must be
smooth and flat. If installing into drywall (Figure 1),
drill 5/32" holes and use anchors provided. For
pre-wired installations (as in new home construction),
it may be mounted to a single gang box (Figure 2).
NOTE: After installation, a green indicator light behind
the cover will indicate proper connection. If not lit, the
Lock and Light features will not function (reverse wires
to correct).
1. Strip 7/16" of insulation from one end of bell wire
and connect to the two screw terminals on back of
door control by color: white wire to 2 and white/red
wire to the 1 (Figure 3).
2. Remove white cover by gently prying at slot in top
of the cover with a small flat head screwdriver.
Fasten with 6ABx1-1/4"self-tapping screws (drywall
installation) or 6-32x1" machine screws (into gang
box) as follows:
• Drill and install bottom screw, allowing 1/8" to
protrude above wall surface.
• Position bottom of door control on screw head and
slide down to secure. Adjust screw for snug fit.
• Install top screw with care to avoid cracking plastic
housing. Do not overtighten.
• Insert top tabs and snap on cover.
NOTE: The push bar may stick if the door control is
not mounted on a smooth surface. If a click is not
heard when pressing the push bar, loosen the two
mounting screws or relocate the door control to a
smoother surface.
3. (Standard installation only) Run bell wire up wall
and across ceiling to motor unit. Use insulated
staples to secure wire in several places. Do not
pierce wire with a staple, creating a short or open
circuit.
4. Strip 7/16" of insulation from end of bell wire.
Connect bell wire to the quick-connect terminals as
follows: white to white and white/red to red.
NOTE: When connecting multiple door controls to the
opener, twist same color wires together. Insert wires
into quick-connect holes: white to white and red/white
to red.
5. Use tacks or staples to permanently attach
entrapment warning label to wall near door control,
and manual release/safety reverse test label in a
prominent location on inside of garage door.
NOTE: DO NOT connect the power and operate the
opener at this time. The trolley will travel to the full
open position but will not return to the close position
until the sensor beam is connected and properly
aligned. See Safety Reversing Sensor Instructions
beginning on page 15.

®
• Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
• 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.
– Install the safety reversing sensor so beam is NO
HIGHER than 6" above garage floor.
CAUTION
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
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.
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 mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.
Sensor Beam
6" max.
above floor
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 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.

TROUBLESHOOTING 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 opener connections.
• 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:
• 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 blink 10 times. (If bulbs are not
installed, 10 clicks can be heard.) See page 15..
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.
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.
• 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.

INSTALLATION STEP 11
Fasten the Door Bracket
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.

WARNING
ADJUSTMENT STEP 1
Adjust the UP and DOWN Travel
Limits
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.
• 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.
CAUTION
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?
• 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 22).
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.
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.
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.
WARNING
CAUTION
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.

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 3" of travel.
NOTE: To prevent the trolley from hitting the cover
protection bolt, keep a minimum distance of 2-4"
between the trolley and the bolt.
Limit Adjustment Screws
ADJUSTMENT LABEL
• 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 3" of travel.
If door still won't close completely and the trolley
bumps into the pulley bracket (page 4), try
lengthening the door arm (page 19) and
decreasing the down limit.
• 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 17.
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 3"
of travel.
20
WARNING
ADJUSTMENT STEP 2
Adjust the Force
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
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 one-inch high object (or 2x4 laid flat) on
floor.
CAUTION
Force adjustment controls are located on the right
side panel of the motor unit. Force adjustment
settings regulate the amount of power required to
open and close the door.
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
• 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 22.
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.
• 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.
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.
• If the door doesn’t open at least 5 feet,
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.

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.
• 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.
CAUTION
TEST
• With the door fully open, 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.
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 19.
• 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.
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).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.

Having a Problem?
3. The door operates from the Door Control, but
not from the remote control:
• Is the door push bar flashing? If your model has
the Lock feature, make sure it is off.
• Program the opener to match the remote control
code. (Refer to instructions on the motor unit
panel.) Repeat with all remotes.
1. The opener doesn't operate from either the
Door Control or the remote control:
• 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.
• 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.
4. The remote control has short range:
• Change the location of the remote control in your
car.
• 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:
• 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.
2. Opener operates from the remote, but not from
the Door Control:
• 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 12.
25
11. The door reverses for no apparent reason and
opener lights blink for 5 seconds after
reversing:
• Check the safety reversing sensor. Remove any
obstruction or align the receiving eye. See
Installation Step 10.
Having a Problem? (Continued)
6. The garage door opens and closes by itself:
• Be sure that all remote control push buttons are
off.
• 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.
• Clear memory and re-program all remote controls.
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.
13. The opener lights don't turn off:
• Is the Light feature on? Turn it off.
7. The door doesn't open completely:
• Is something obstructing the door? Is it out of
balance, or are the springs broken? Remove the
obstruction or repair the door.
• 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 3
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:
• Review the travel limits adjustment procedures on
page 20.
Repeat the safety reverse test after any adjustment
of door arm length, close force or down limit.
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.
15. The opener motor hums briefly, then won't
work:
• The garage door springs may be broken. See
above.
• 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.
9. The door opens but won't close:
• If the opener lights blink, check the safety
reversing sensor. See Installation Step 10.
• If the opener lights don’t blink and it is a new
installation, check the down force. See Adjustment
Step 2. For an existing installation, see below.
Repeat the safety reverse test after the adjustment
is complete.
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 24.
• 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.
10. The door reverses for no apparent reason and
opener lights don’t blink:
• 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.
• Clear any ice or snow from the garage floor area
where the door closes.
• Review Adjustment Step 2.
• 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.
17. The chain droops or sags:
• 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.)
