INSTALLATION STEP 1

Determine the Header Bracket Location

To prevent possible SERIOUS INJURY or DEATH:

• Header bracket MUST be RIGIDLY fastened to
structural support on header wall or ceiling,
otherwise garage door might NOT reverse when
required. DO NOT install header bracket over
drywall.

• Concrete anchors MUST be used if mounting
header bracket or 2x4 into masonry.

• NEVER try to loosen, move or adjust garage
door, springs, cables, pulleys, brackets, or their
hardware, ALL of which are under EXTREME
tension.

• ALWAYS call a trained door systems technician if
garage door binds, sticks or is out of balance. An
unbalanced garage door might NOT reverse when
required.

Installation procedures vary according to garage door
types. Follow the instructions which apply to your door.

1. Close the door and mark the inside vertical centerline of
the garage door.

2. Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 feet

(1.22 m) of the left or right of the door center only if
a torsion spring or center bearing plate is in the way;
or you can attach it to the ceiling (see page 9) when
clearance is minimal. (It may be mounted on the wall
upside down if necessary, to gain approximately
1/2" (1 cm).)

If you need to install the header bracket on a 2x4

(on wall or ceiling), use lag screws (not provided) to
securely fasten the 2x4 to structural supports as shown
here and on page 9.

3. Open your door to the highest point of travel as shown.
Draw an inter secting horizontal line on the header wall
above the high point:

• 2" (5 cm) above the high point for sectional door

and one-piece door with track.

• 8" (20 cm) above the high point for one-piece door

without track.

This height will provide travel clearance for the top edge

of the door.

NOTE: If the total number of inches exceeds the height

available in your garage, use the maximum height
possible, or refer to page 9 for ceiling installation.

INSTALLATION STEP 5

Hang the Opener

Three representative installations are shown. Yours may
be different. Hanging brackets should be angled
(Figure 1) to provide rigid support. On fi nished ceilings
(Figure 2 and Figure 3), attach a sturdy metal bracket
to structural supports before installing the opener. This
bracket and fastening hardware are not provided.

1. Measure the distance from each side of the motor unit
to the structural support.

2. Cut both pieces of the hanging bracket to required
lengths.

3. Drill 3/16" pilot holes in the structural supports.

4. Attach one end of each bracket to a support with
5/16"-18x1-7/8" lag screws.

5. Fasten the opener to the hanging brackets with
5/16"-18x7/8" hex bolts, lock washers and nuts.

6. Check to make sure the rail is centered over the door
(or in line with the header bracket if the bracket is not
centered above the door).

7. Remove the 2x4. Operate the door manually. If the door
hits the rail, raise the header bracket.

NOTE: DO NOT connect power to opener at this time.

To avoid possible SERIOUS INJURY from a falling
garage door opener, fasten it SECURELY to structural
supports of the garage. Concrete anchors MUST be

Install the Door Control

Locate door control within sight of door at a minimum
height of 5 feet (1.5 m) where small children cannot
reach, and away from moving parts of door and door
hardware. The installation surface must be smooth and
fl at. 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 or

amber 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" (11 mm) 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 WHT and white/red
wire to the RED (Figure 3).

2. Remove cover by gently prying at slot in the top of the
cover with a small fl at head screwdriver (Figure 4).
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" (3 mm)

to protrude above wall surface.

• Position bottom of door control on screw head and

slide down to secure. Adjust screw for snug fi t.

• Install top screw with care to avoid cracking plastic

housing. Do not overtighten.

• Insert bottom 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" (11 mm) 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 (Figure 5).

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 power and operate 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.

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
(1.5 m), 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.

Install the Light

• Press the release tabs on both sides of lens. Gently
rotate lens back and downward until the lens hinge is in
the fully open position. Do not remove the lens.

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

• Reverse the procedure to close the lens.

• Use A19, standard neck garage door opener bulbs for
replacement.

NOTE: Use only standard light bulbs. The use of short neck
or speciality light bulbs may overheat the endpanel or light
socket.

To prevent possible OVERHEATING of the endpanel or
light socket:

• DO NOT use short neck or specialty light bulbs.

• DO NOT use halogen bulbs. Use ONLY
incandescent.

To prevent damage to the opener:

• DO NOT use bulbs larger than 100W.

• ONLY use A19 size bulbs.

Attach the Emergency Release Rope and Handle

• Thread one end of the rope through the hole in the top
of the red handle so “NOTICE” reads right side up as
shown. Secure with an overhand knot at least 1"
(2.5 cm) from the end of the rope to prevent slipping.

• Thread the other end of the rope through the hole in the
release arm of the outer trolley.

• Adjust rope length so the handle is 6 feet (1.83 m)
above the fl oor. Ensure that the rope and handle clear
the tops of all vehicles to avoid entanglement. Secure
with an overhand knot.

NOTE: If it is necessary to cut the rope, heat seal the cut
end with a match or lighter to prevent unraveling.

To prevent possible SERIOUS INJURY or DEATH from
a falling garage door:

• If possible, use emergency release handle to
disengage trolley ONLY when garage door is
CLOSED. Weak or broken springs or unbalanced
door could result in an open door falling rapidly
and/or unexpectedly.

• NEVER use emergency release handle unless
garage doorway is clear of persons and
obstructions.

• NEVER use handle to pull door open or closed. If
rope knot becomes untied, you could fall.

INSTALLATION STEP 9

Electrical Requirements

To avoid installation diffi culties, do not run the opener
at this time.

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 fi t into a grounding type outlet.
If the plug doesn’t fi t into the outlet you have, contact a
qualifi ed electrician to install the proper outlet.

RIGHT WRONG

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

To make a permanent connection through the 7/8" hole in
the top of the motor unit:

• Remove the motor unit cover 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.

• Reinstall the cover.

To avoid installation diffi culties, do not run the opener
at this time.

To prevent possible SERIOUS INJURY or DEATH from
electrocution or fi re:

• Be sure power is NOT connected to the opener, and
disconnect power to circuit BEFORE removing cover
to establish permanent wiring connection.

• Garage door installation and wiring MUST be in
compliance with ALL local electrical and building
codes.

• NEVER use an extension cord, 2-wire adapter, or
change plug in ANY way to make it fi t outlet. Be sure
the opener is grounded.

INSTALLATION STEP 10

Install The Protector System

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 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 fl ash 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" (15 cm) above the fl oor. 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.

®

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" (15 cm) above garage fl oor.

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.

INSTALLING THE BRACKETS

Be sure power to the opener is disconnected. Install

and align the brackets so the sensors will face each other
across the garage door, with the beam no higher than
6" (15 cm) above the fl oor. They may be installed in one of
three ways, as follows.

Garage door track installation (preferred) (Figure 1):

• Slip the curved arms over the rounded edge of each
door track, with the curved arms facing the door. Snap
into place against the side of the track. It should lie
fl ush, with the lip hugging the back edge of the track,
as shown in Figure 1.

If your door track will not support the bracket securely,
wall installation is recommended.

Wall installation (Figures 2 & 3):

• Place the bracket against the wall with curved arms
facing the door. Be sure there is enough clearance for
the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket
(see Accessories) or wood blocks can be used.

• Use bracket mounting holes as a template to locate and
drill (2) 3/16" diameter pilot holes on the wall at each
side of the door, no higher than 6" (15 cm) above the
fl oor.

• Attach brackets to wall with lag screws (Not provided).

• If using extension brackets or wood blocks, adjust
right and left assemblies to the same distance out from
the mounting surface. Make sure all door hardware
obstructions are cleared.

Floor installation (Figure 4):

• Use wood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the lenses
will be no higher than 6" (15 cm) above the fl oor.

• Carefully measure and place right and left assemblies
at the same distance out from the wall. Be sure all door
hardware obstructions are cleared.

• Fasten to the fl oor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY REVERSING SENSORS

Mounting:

• Slide a 1/4"-20x1/2" 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).

• Finger tighten the wing nuts.

Option A - Installation Without Pre-Wiring:

• Run the bell wire from both sensors to the garage
door opener. Attach the wire to the wall and ceiling
with the staples (Figure 6).

Option B - Pre-Wired Installation:

If your garage already has wires installed for the safety
reversing sensors, follow the instructions below:

• Cut the end of the safety sensor wire, making sure there
is enough wire to reach the pre-installed wires from the
wall (Figure 7).

• Separate the safety sensor wires and strip 7/16 inch
(11 mm) of insulation from each end. Choose two of
the pre-installed wires and strip 7/16 inch (11 mm) of
insulation from each end. Make sure that you choose
the same color pre-installed wires for each sensor
(Figure 8).

• Connect the pre-installed wires to the sensor wires with
wire nuts making sure the colors correspond for each
sensor (Figure 9).

ALIGNING THE SAFETY REVERSING 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 amber indicator light will glow regardless
of alignment or obstruction. If the green indicator light in
the receiving eye is off, dim, or fl ickering (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.

TROUBLESHOOTING THE SAFETY REVERSING 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. See page 15.

INSTALLATION STEP 11

Fasten the Door Bracket

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.

SECTIONAL DOORS

1. Center the door bracket on the previously marked
vertical centerline used for the header bracket
installation. Note correct UP placement, as stamped
inside the bracket.

2. Position the top edge of the bracket 2"-4" (5-10 cm)
below the top edge of the door, OR directly below any
structural support across the top of the door.

3. Mark, drill holes and install as follows, depending on
your door’s construction:

Metal or light weight doors using a vertical angle
iron brace between the door panel support and the door
bracket:

• Drill 3/16" fastening holes. Secure the door bracket
using the two 1/4"-14x5/8" self-threading screws
(Figure 2A).

• Alternately, use two 5/16" bolts, lock washers and nuts
(not provided) (Figure 2B).

Metal, insulated or light weight factory reinforced doors:

• Drill 3/16" fastening holes. Secure the door bracket
using the self-threading screws (Figure 3).

Wood Doors:

• Use top and bottom or side to side door bracket holes.
Drill 5/16" holes through the door and secure bracket
with 5/16"x2" carriage bolts, lock washers and nuts
(not provided) (Figure 4).

NOTE: The 1/4"-14x5/8" self-threading screws are not
intended for use on wood doors.

Connect Door Arm to Trolley

Follow instructions which apply to your door type as
illustrated below and on the following page.

SECTIONAL DOORS ONLY

• Make sure garage door is fully closed. Pull the
emergency release handle to disconnect the outer
trolley from the inner trolley. Slide the outer trolley
back (away from the door) about 2" (5 cm) as shown in
Figures 1, 2 and 3.

• Figure 1:

– Fasten straight door arm section to outer trolley

with the 5/16"x1" clevis pin. Secure the connection
with a ring fastener.

– Fasten curved section to the door bracket in the

same way, using the 5/16"x1-1/4" clevis pin.

IMPORTANT: The groove on the straight door arm MUST
face away from the curved door arm (Figure 4).

• Figure 2:

– Bring arm sections together. Find two pairs of holes

that line up and join sections. Select holes as far
apart as possible to increase door arm rigidity.

• Figure 3, Hole alignment alternative:

– If holes in curved arm are above holes in straight

arm, disconnect straight arm. Cut about 6" (15 cm)
from the solid end. Reconnect to trolley with cut
end down as shown.

– Bring arm sections together.

– Find two pairs of holes that line up and join with

bolts, lock washers and nuts.

• Pull the emergency release handle toward the opener at
a 45° angle so that the trolley release arm is horizontal.
Proceed to Adjustment Step 1, page 23. Trolley will

• Open door adjustment: decrease UP travel limit

- Turn the UP limit adjustment screw

counter-clockwise 4 turns.

- Press the Door Control push button. The trolley will

travel to the fully open position.

- Manually raise the door to the open position (parallel

to the fl oor), 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 3" (7.5 cm) of trolley travel.

• Closed door adjustment: decrease DOWN

travel limit

- Turn the DOWN limit adjustment screw clockwise

4 complete turns.

- Press the Door Control push button. The trolley will

travel to the fully closed position.

closed trolley/door arm positions in the illustration. If
the arm is behind the connector hole, adjust the limit
further. One full turn equals 3" (7.5 cm) of trolley
travel.

3. Connect the door arm to the trolley:

• 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.

• 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 fl oor.

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 or closed from the fully open position.

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?

• 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 25).

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. 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.

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 1-1/2" high (3.8 cm) object
(or 2x4 laid fl at) on fl oor.

To prevent damage to vehicles, be sure fully open door
provides adequate clearance.

Cover Protection
Bolt

HOW AND WHEN TO ADJUST THE LIMITS

• If the door does not open completely but opens at
least fi ve feet (1.5 m):

Increase up travel. Turn the UP limit adjustment screw

clockwise. One turn equals 3" (7.5 cm) of travel.

NOTE: To prevent the trolley from hitting the cover

protection bolt, keep a minimum distance of 2-4"
(5-10 cm) between the trolley and the bolt.

• If door does not open at least 5 feet (1.5 m):

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" (7.5 cm)
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 21) and decreasing the down limit.

• If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit adjustment

screw clockwise. One turn equals 3" (7.5 cm) of travel.

2-4"

(5-10 cm)

Left Side Panel Limit Adjustment Screws

ADJUSTMENT LABEL

• If the door reverses when closing and there is no
visible interference to travel cycle:

If the opener lights are fl ashing, the Safety Reversing

Sensors are either not installed, misaligned, or
obstructed. See Troubleshooting, page 18.

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.

23

ADJUSTMENT STEP 2

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.

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 1-1/2" (3.8 cm) obstruction.
See Adjustment Step 3, page 25. 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 fl ashing, 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 (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.

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 1-1/2" high (3.8 cm) object
(or 2x4 laid fl at) on fl oor.

Test the Safety Reversal System

TEST

• With the door fully open, place a 1-1/2" (3.8 cm) board
(or a 2x4 laid fl at) on the fl oor, 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 21.

• 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.

• If the unit continues to fail the Safety Reverse Test, call
for a trained door systems technician.

IMPORTANT SAFETY CHECK:

Test the Safety Reverse System 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 fl oor.

• Any repair to or adjustment of the opener.

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 1-1/2" high (3.8 cm) object
(or 2x4 laid fl at) on the fl oor.

1-1/2" (3.8 cm) board
(or a 2x4 laid fl at)

ADJUSTMENT STEP 4

Test The Protector System

• Press the remote control push button to open the door.

• Place the opener carton in the path of the door.

• Press the remote control push button to close the door.
The door will not move more than an inch (2.5 cm),
and the opener lights will fl ash.

The garage door opener will not close from a remote if the
indicator light in either sensor is off (alerting you to the
fact that the sensor is misaligned or obstructed).

If the opener closes the door when the safety reversing
sensor is obstructed (and the sensors are no more than
6" (15 cm) above the fl oor), call for a trained door
systems technician.
