PRODUCT FEATURES
The purpose of this booklet is to provide assembly,
installation and operation information concerning the
Challenger AC9000 Series (Models AC9300, AC9500, and
ACJ9500) Residential Garage Door Openers and related
Accessory Products.
NOTICE
IT IS IMPORTANT THAT THIS INSTRUCTION
MANUAL BE READ AND UNDERSTOOD
COMPLETELY BEFORE INSTALLATION OR
OPERATION IS ATTEMPTED.
NOTICE
THE IMPORTANT SAFEGUARDS AND
INSTRUCTIONS IN THIS MANUAL CANNOT
COVER ALL POSSIBLE CONDITIONS AND
SITUATIONS WHICH MAY OCCUR DURING ITS
USE. IT MUST BE UNDERSTOOD THAT
COMMON SENSE AND CAUTION MUST BE
EXERCISED BY THE PERSON(S) INSTALLING,
MAINTAINING AND OPERATING THE
EQUIPMENT DESCRIBED HEREIN. DO NOT
USE THIS EQUIPMENT FOR ANY OTHER THAN
ITS INTENDED PURPOSE - OPERATING
OVERHEAD GARAGE DOORS.
STANDARD FEATURES:
Safe Finish™ Photosystem: An invisible infrared beam of
light guards the door opening and reverses a downward moving
door if the beam is broken by a stationary or moving object.
The AC9000 Series motor control circuitry constantly monitors
the Safe Finish Photosystem for proper operation.
Manual Release: A pull cord allows separation of the drive
mechanism and manual operation of the door when desired, as
in the event of a power failure. (Page 16)
Automatic Reconnection: Once power is restored, or
automatic operation of the door is again desired, initiating
operation in the normal manner (Push Button, Radio Control,
etc.) will effect automatic reconnection of the Manual Release
Mechanism. (Page 16)
Alternating Action Operation:The mechanical wall
pushbutton functions in an Open/Stop/Close/Stop mode in
normal operation. (Page 16)
Sensing System: A built-in sensing system detects
obstructions during door operation. If in the downward
(close) travel mode, the Opener will sense an obstruction
and reverse the direction of the door. In the open mode,
the Opener will stop. Since all doors are different, the
Sensing System has independent adjustments for
customizing the level of force required for the normal
opening and closing of specified doors. ( Page 18)
Close Limit Switch: In winter months it's common
for small pieces of ice or packed snow to be trapped
under the door. Ground swelling can also effect the
close limit setting of the Opener. The AC9000 Series
Close Limit Switch overrides the Sensing System during
the last one inch of closing travel and prevents the door
from reversing if it encounters an obstruction at this
point.
Constant Contact To Close: For utmost safety and
security, the standard operation mode requires constant
contact on the mechanical Push Button to close the door
if the Safe Finish™ Photosystem becomes misaligned
or if there is an irregularity in the wiring to the device.
In this mode of operation, a Radio Transmitter cannot be
used to close the door. (Page 19)
OPTIONAL FEATURES:
Digital Radio Controls: The AC9000 Series
Openers covered in this Manual can be fitted with
Allstar’s optional Radio Controls. Up to 19,683 private
codes can be easily selected without use of tools.
(PageZ14)
Super Station Deluxe Wall Push Button: A
feature-packed accessory unit, the Deluxe Wall Station
allows access to all of the Opener's functions. Open/
Close button permits full control of the door’s operation.
The Opener's built-in light can be turned on or off
independent of door operation. A Security Switch
allows the Opener to be deactivated for extended periods
of time. (Page 12)
Keyless Entry System: A tamper resistant outdoor
keypad, the optional Keyless Entry System permits entry
to the garage without use of key or radio transmitter.
Easily programmable, it accommodates four separate
access codes of 4 digits. Lighted Buttons enhance
nighttime use.

NOTE: The Rail/Chain Assembly is
packaged separately from the Power
Head Unit. The trolley, front idler/
tension adjustment assembly, chain,
drive gear and limit cams are assembled
to the Rail/Chain Assembly at the
factory. Follow the steps outlined
below to complete assembly prior to
installation. Refer to the component
identification illustrations on the
previous page.
STEP 1: Prior to attaching the motor
drive unit to the rail assembly, the Open
and Close adjustment bolts must be
installed. Place the threaded end of the
adjustment bolt through the hole in the
rail and then slip the head of the bolt
through the center of the double key
hole. Slide the spring over the bolt and attach load adjusting nut. Tighten until the tip of the bolt extends 3/16” outside the nut.
Repeat above for the other side.
STEP 2: Protect the Power Unit cover from scratching during assembly by placing it on cardboard. Loosen the two 5/16" lock
washer nuts on top of the power head drive unit.
STEP 3: VERY IMPORTANT ! Position a paper shim around the power head unit drive gear (standard weight paper, see
illustration). Shim must remain in place while assembling the power head unit to the Rail/Chain assembly to ensure a proper gear
mesh and avoid excessive long term wear.
STEP 4: Align the four key holes in the Rail/Chain assembly with
the two front guide tabs and the two rear bolt studs on the power
head unit and place the rail/chain assembly in place over the power
head unit. The power head drive unit limit lever protrudes up
through the rail/chain assembly sensing plate. Take care not to bend
the lever when
assembling. Slide the
power head drive unit
forward until the gear
meshes with the rail/
chain assembly drive
gear. Check to make
sure the front guide tabs
on the power head unit
are securely locked on
the rail/chain assembly.
STEP 5: The power head drive unit should be move forward until
all play between the gears has been eliminated, but no additional force should be used that could cause pressure on the motor (power
head unit) drive gear. Tighten the two 5/16" lock washer nuts on top of the power head drive unit that were loosened in Step 2 above.
When the opener is first activated the paper shim will be ejected. The paper shim should have the profile of the gears to indicate the
proper mesh between them.
STEP 6: Recheck the nuts used to secure the Rail/Chain assembly to the Power Head Unit, making sure they are tight.
Assembly is now complete and you are ready to begin installation of the opener.
If Your Opener Is Supplied Fully Assembled, Please Disregard This Page.

STEP 1: Mounting the Front Bracket — Sectional Doors and One-
Piece Doors with Track (For One-Piece Doors without track see Step 1A,
next): Mark a vertical centerline on the header above the door. By
manually raising the door, determine the high arc of the door’s travel (see
illustration, top of previous page) and using a level, transfer this
measurement to the header (see illustration at left). Draw a horizontal line,
crossing the previously drawn centerline, at this point. Install the Front
Mounting Bracket securely wit lag screws as shown below. If necessary,
reinforce the header with steel angle iron or wood to ensure a secure
mount.

STEP 4: Mount Power Head to Ceiling: Since there is such variety in ceiling structures, all the mounting possibilities for the Power
Unit cannot be illustrated here. The main concern is mounting the Power Unit securely to the ceiling joists for operational strength,
rigidity and safety. Although there are a series of mounting slots provided on the power unit, try to secure the mounting straps in
the slots closest to the front. Mounting
may usually be accomplished using
standard 1-1/4“ perforated steel angle
available at most hardware stores. If in
doubt about location of, and attachment to,
ceiling joists, a carpenter should be
contacted to provide assistance. A cross
brace will be necessary if power head is
mounted 8” or more from the ceiling.
STEP 5: Return to the Rail/Wall
Mounting Bracket and securely tighten
the bolt and nut that connect the Rail Front
Idler bracket and the Wall Mounting
Bracket. Take care not to over tighten the
nut; tighten only until the end of the bolt is
(See Step 2).

STEP 6: Align the center of opener tracks
with the center line previously marked on the
top section of the garage door to ensure rail
will be parallel with the direction of door
travel.
Use supplied hangers from the ceiling beams
to hang the opener at the power head end (be
sure to locate and mount to the solid structural
beams, as illustrated). Predrill with 3/16” drill
bit and use supplied 1/4” x 1-1/2” lag screws
to ensure a rigid mount.
NOTE: Hanging brackets should be at an
angle to provide rigid support. If hangers have no angle or if you use longer hangers, cross brace the
hangers to eliminate the possibility of sway during operation of the opener.

Visually align the door arm connecting hole with the middle hole of
the door bracket by rotating the tube section in the appropriate
direction.
Release the trolley (leave door arm attached) with the manual release
cord and pull trolley toward the power head unit. Now rotate the door
arm tube section two turns counterclockwise (increasing the exposed
length of the door rod) to provide a cushion when the door is closed or
encounters an obstruction. Align connecting hole in the door arm to
middle hole in the door bracket; insert 3/8” diameter bolt and tighten
locking nut, allowing for free pivot of the arm. Note: Do not
overtighten locking nut as this will cause binding between the door
arm and door bracket.
110054-2
Type 2: Strut Mounted Bracket
Visually align the door arm connecting hole with the connecting
pin of the strut by rotating the tube section in the appropriate
direction.
Release the trolley (leave door arm attached) with the manual
release cord and pull trolley toward the power head unit. Now
rotate the door arm tube section two turns counterclockwise
(increasing the exposed length of the door rod) to provide a cushion
when the door is closed or encounters an obstruction. Align
connecting hole in the door arm with the strut mounted connecting
bracket. Insert connecting pin through the hole in the door arm.
Secure the connecting pin to the strut bracket according to the
manufacturer’s instructions.

110051-3
C: INSTALLING THE OPERATOR
STEP 11: Connecting The Electrical Power Consult the label on the rear panel of the Opener to determine its proper
working voltage. Normally it will be marked for 115V, 60 cycle operation. (If it is an export model designed for 220V, 50 cycle
operation, the label will clearly indicate this.) The Opener must be plugged into a properly grounded receptacle within 3 FT of the
Power Unit. A GFI Type receptacle is recommended. Do not use 2-prong adapters and do not use extension cords for anything
more than temporary hook-up and testing purposes. Receptacle wiring should be No. 14 or heavier, and must be in compliance with
local building and electrical codes.
If local codes require permanent wiring, a GFI type circuit
breaker is recommended to protect the line. Remove the Strain
Relief Bushing and withdraw the Line Cord from the rear of the
Power Unit to expose the three insulated connectors. Cut the
wire at the rubber jacket of the Line Cord and wire in
permanently, employing proper wiring practices. Discard Strain
Relief. It is not used with permanent wiring.
Using the two wires (black & white) that were left when you
cut off the line cord, splice in the permanent connections.

D: CONTROL AND AUXILIARY EQUIPMENT
INSTALLATION OF A STANDARD WALL PUSH BUTTON OR DELUXE WALL STATION CONTROL
A standard wall push button is included
in your hardware package, an optional
Deluxe Wall Station may be purchased
from your installing dealer. The operat-
ing parameters for the standard wall
push button and the Deluxe Wall Station
are outlined on pages that follow
(“Operating Instructions”) to see what
mode of operation is right for you. All-
star recommends the Deluxe Wall Sta-
tion installation, as it will provide full
control over the garage door operator and its functions at all times. You may install one Deluxe Wall Station and one or more stan-
dard push buttons to a Challenger AC9000 Series operator following the cautions and instructions outlined below.
STEP 1: After determining a suitable location, usually near the access door and at least 5 feet above the floor to prevent use by
children, use the standard wall push button or Deluxe Wall Station as a guide to mark the mounting holes. Drill holes for drywall
anchors or screws. NOTE: Do not mount directly to masonry walls. Use backer board.
STEP 2: A length of 2-conductor, #22 gauge wire (or heavier) is required to connect the control button to the garage door operator.
Strip approximately 2” of the wire jacket from one end and 1/2” of insulation from each wire. Carefully connect one wire to each of
the two terminals. Carefully tuck the loose wires into the case and mount the unit using appropriate screws.
STEP 3: Run the wire from the control button to the operator, supporting it at 18” intervals with suitable staples. Leave a
sufficient length to make the necessary connections to the operator terminal strip.
WARNING: SOME LOCAL BUILDING CODES DO NOT ALLOW
SURFACE WIRING. BE SAFE AND CHECK WITH YOUR LOCAL
BUILDING INSPECTOR FIRST.
STEP 4: Ensure power is OFF to the operator or disconnect the power from the
operator. Strip approximately 4” of jacket from the end of the wire and 1/2”
insulation from each wire. Connect to terminals 0 and 1 as shown in the
illustration. Support the wire near the operator with wire ties.
Step 5: Install the
Control Button
Warning Label
supplied with your
Challenger AC9000
Series operator near
the control button
(see illustration).
Repeat the Steps 1
thru 5 above to in-
stall additional stan-
dard wall push but-
tons if desired.

SAFE FINISH™ PHOTOSYSTEM INSTALLATION
Identify which side of the garage door opening (if any) the sun is “likely” to shine
into. As sunlight may cause undesirable operation, mount the sending unit (black
button below the window) on the side of the door opening exposed most to the sun.
STEP 1: Mounting the Photosystem Wall Brackets Select a
mounting position 5 inches above the floor to the center line wall bracket. The
sending and receiving units should be mounted inside the door opening to minimize
any interference by the sun. However, the sensors should be mounted as close to
the door track or inside edge of the door as possible to offer maximum entrapment
protection. The brackets may be temporarily
mounted to the wall (or jamb) with the 1” flathead
nail provided. Leave this nail in place after
installation of the lag screw below to prevent
accidental rotation of the bracket NOTE: It is very important that the wall brackets be mounted at
exactly the same height so they will be aligned.
Using the 1/4” x 1-1/2” lag screw provided, attach the wall bracket securely to the wall. In some
installations it may be necessary to attach wooden spacers to the wall to achieve the required
clearance. Expansion bolts (not supplied) may be required to attach brackets to walls constructed of
materials other than wood or gypsum. Repeat for the wall bracket on the other side of the door
opening.
STEP 2: Wire Connect the Photosystem
Refer to page 20 for wiring diagrams of the Safe Finish™ Photosystem and garage door opener. The following outlines the
“PHOTOCELL SERIES CONNECTION (RECEIVER FIRST)” wiring diagram.
A. Run a wire pair (not supplied) around the garage door jamb between the transmitter and receiver "L" mounting brackets.
NOTE: Leave about 12” of extra wire at each end. Use a minimum 22 gauge solid "trace" wire (one wire in set should be
marked to identify it at each end) for interconnect.
B. Run a wire pair (20 or 22 gage solid wire) from the receiver position (unit with "LED" light in the front, may be either side of
the door) back to the rear bulkhead of the garage door opener. NOTE: Leave about 12” of extra wire at the receiver end and
about 24” of extra wire at the opener end. Use a minimum 22 gauge solid "trace" wire (one wire in set should be marked to
identify it at each end) for interconnect.
C. Strip approximately 5/16” from each wire end at the photosystem units and at the opener.
D. Using two (2) wire nuts (supplied), connect the wire ends at the Safe Finish™ Photosystem transmitter to the pigtail wire ends
coming out of the transmitter unit. Observe polarity, connect the trace wire ends (with black stripe) together and the
unmarked wire ends together. See wiring diagrams on page 20 .
Using two (2) wire nuts (supplied), connect the wire ends at the SAFE FINISH™ Photosystem receiver to the pigtail wire ends
coming out of the receiver unit. Observe polarity, connect the trace wire ends (with black stripe) together and the
unmarked wire ends together.
STEP 3: Final Installation of Photosystem Units
A. Attach the"U" brackets to the "L" brackets with a 1/4-20 carriage bolt,
washer and hex nut (provided). Insert the bolt from the inside of the
"U" bracket and hand tighten only at this time.
B. Place the transmitter and receiver units into their respective "U"
brackets. NOTE: It is easier to slip the photosystem units in from the
side of the bracket than forcing them in from the front of the bracket.
See Illustration, at right.
C. Connect the interconnect wire pair to the garage door opener terminals.
Connect the trace wire (with black stripe) to the operator
terminal marked “4” and the solid color wire to the operator
terminal marked “5”. See Wiring Diagrams on page 20 .

Setting The Coding Switches: When setting the Coding Switches THE FACTORY
PRE-SET CODES MUST BE CHANGED TO PREVENT UNAUTHORIZED
OPERATION. Transmitter and Receiver codes must be set IDENTICALLY. If just
one Code Switch is mismatched, the Radio Controls will not function.
NOTE: For security reasons, it is advisable NOT to set all the switches in the
same position.
Mounting The Receiver: After setting the Coding Switches, mount the Receiver on
the rear panel of the Opener by connecting it to Terminals 1, 2 and 3. For proper
operation, the Antenna Wire should be POINTED STRAIGHT DOWN toward the
floor.
After installing the Radio
Controls, check their operation
by moving approximately 35
FT away from the garage door
and pressing the Transmitter
Button. Operation at this
distance should be reliable.
If the Transmitter doesn't
activate door operation, check
that all Coding Switches are set
identically. If the operational
distance is inadequate, try
moving the position of the
Transmitter in the car. If the distance is still inadequate, try bending the Antenna Wire
to a different angle. If the distance is still
inadequate, replace the Battery with a standard 9-
Volt “transistor radio” Battery (NEED 1604). The
Battery is located in the front compartment next to
the Coding Switches.
The Transmitter may be hand held if desired by
removing the Visor Clip from the rear of the Case

•KEEP THE GARAGE DOOR PROPERLY BALANCED. See the door owner's manual. An
improperly balanced door MAY CAUSE SEVERE INJURY OR DEATH. Have a QUALIFIED
SERVICE PERSON MAKE REPAIRS TO CABLES, SPRING ASSEMBLIES AND OTHER
HARDWARE.
•SAVE THIS INSTRUCTION MANUAL.
WARNING
TO REDUCE THE RISK OF SEVERE
INJURY OR DEATH: READ AND FOLLOW
ALL USER / SAFETY INSTRUCTIONS!
TURNING ON POWER TO THE OPERATOR
NOTE: It is now necessary to turn on the power in order to run the Opener to test the operation and check the
limit settings. Before doing so, ensure that all mounting hardware is installed and has been properly tightened,
that all electrical connections are per local code requirements, and that proper wiring practices have been
followed. Also, double-check that all ropes have been removed from the door and that the doorway is clear.
BASIC OPERATING PARAMETERS
Please note the following Operating Parameters which apply to Openers with Auxiliary Entrapment Protection System (Safe Fin-
ish™ Photosystem, Installation Instructions on Page 13) and a standard wall push button connected. Please see page 17 for instruc-
tions concerning the Deluxe Wall Push Button operating parameters.
HOW TO ACTIVATE THE OPENER
Never let children operate or play with the door controls. Keep Remote Control Away for Children.
Use any of the following devices:
1. The Remote Control Transmitter. Hold the push button down until the door starts to move, then release button.
2. The Door Control Button. Momentary push of the button until the door starts to move. Constant push of the button until the
door is closed is required if light flashes.
3. An Outside Keylock or Keyless Entry System (if you have installed either of these options, see Mfg’s instructions).

E: OPERATION AND ADJUSTMENT INSTRUCTIONS
HOW THE DOOR MOVES WHEN THE OPENER IS ACTIVATED
Always keep moving door in sight and away from people and objects until it is completely closed
NO ONE SHOULD CROSS THE PATH OF A MOVING DOOR.
IF THE DOOR IS...
...FULLY OPEN, then pushing the standard wall Push Button or the radio control will cause the door to begin MOVING
DOWNWARD.
...FULLY CLOSED, then pushing the wall Push Button or the radio control will cause the door to begin MOVING UPWARD.
...MOVING UPWARD, then pushing the wall Push Button will cause the door to STOP. The next push of the wall button will
cause the door to begin MOVING DOWNWARD (Alternate Action Operation).
...MOVING DOWNWARD, then pushing the wall Push Button or the radio control will cause the door to STOP. The next
activation will cause the door to BEGIN MOVING UPWARD.
...MOVING DOWNWARD and an obstruction is encountered, the door will STOP, PAUSE AND REVERSE TO THE OPEN
DIRECTION.
...MOVING UPWARD and an obstruction is encountered, the door will STOP. The next activation will CLOSE the door.
The SAFE FINISH PHOTOELECTRIC uses an invisible beam which, when broken by an obstruction, causes a closing door to open
and prevents an open door from closing.
HOW THE LIGHT WORKS AND WHAT IT MEANS WHEN IT FLASHES
1. The convenience light automatically turns on when the opener is activated and remains on for 4-1/2 minutes for your convenience
and safety.
2. The light will flash after coming upon an obstruction in the down direction to alert you of a problem. It will continue to flash for
4-1/2 minutes, then shut off.
3. Optional Wall Station adds the convenience of allowing the light to be turned on and stay on until turned off by a second push of
the button or activation of door cycle.
If the light begins to flash and the door does not move in the close direction from a push button or radio, the
external safety device (Safe Finish Photoelectric) is activated or defective (misaligned or blocked etc.). To
temporarily override and close door, activate pushbutton or wall station for 2 seconds; opener will begin moving
in the down direction. The button must remain depressed until the cycle is completed. If the button is released
before cycle is completed, the door will reverse and come to a fully open position. Problems with the safety system
should be inspected by a professional garage door installer.
HOW TO OPERATE THE DOOR MANUALLY - MANUAL RELEASE DISCONNECT
The door should be fully closed, if possible, before using the manual disconnect. Weak or broken springs
could allow an open door to fall rapidly. Property damage or serious personal injury could result. Do not
use the manual release handle to pull the door open or closed.
Your opener is equipped with a manual release recessed trolley-type disconnect
system, enabling manual operation of the garage door during a power failure.
The trolley is disconnected from the chain by pulling down on the red release
handle, allowing the garage door to be operated manually.
The trolley will automatically reconnect when power is restored and the door is
activated.
If the manual release is used, close the door before reactivating the opener.
NOTE: Outside keylock manual releases are an available accessory and are recommended for garages without a service
entrance.

E: OPERATION AND ADJUSTMENT INSTRUCTIONS
Adjustment #1: Opening Travel
Your opener is assembled at the factory with the trolley in the forward position with the
open limit stops snapped in place on the chain, set for a standard door.
If you door is non-standard, move BOTH open limit stops, located just behind the trolley.
As an example: For a 6 FT, 6 INCH door, move both open limit stops six inches or 12 links
toward the power head unit.
To confirm final opening travel adjustment, activate the opener to bring the foor to the
fully open position. When properly adjusted, center of the open limit stops should come to
rest opposite the load adjusting nut.
NOTE: If the door drifts forward, move the open limit stops toward the
power head unit. If the door does not drift forward it is still advised that you
perform one additional check. Operate manual release on the trolley and
allow the door to seek its natural fully open position, then move the open limit
stops to align trolley to this position. If the door does not open fully at its
natural open position, it indicates a door spring or hardware problem that
should be referred to a door system professional.
(See instruction label on side of track for proper limit stop location.)
Adjustment #2: Opening and Closing Force
Hex nuts for adjusting force are located on either side of the rail at the motor end.
The left hex nut, labeled “CLOSE”, adjusts the closing force; the right hex nut,
labeled “OPEN”, adjusts the opening force.
Turning the hex nuts clockwise increases force; counterclockwise decreases force.
Your garage door opener is built with a safety system that allows the door to reverse
in the close direction and stop in the open direction. This must be adjusted so your
opener does not use excessive force in the down direction or react to the weight of the
door during upward travel.
To help determine that the force is not excessive, grasp the door handle or bottom
edge during downward travel. The opener should reverse to this force. Do not stand
under the door during this test.
If the handle is hard to hold and the door does not reverse, adjust the CLOSE hex nut to decrease force until the door reacts properly.
Repeat the adjustment procedure for upward travel. The door should stop without using excessive force.
DO NOT USE ADJUSTMENTS TO COMPENSATE FOR A POORLY WORKING DOOR. THIS WILL
INTERFERE WITH THE PROPER OPERATION OF THE REVERSING MECHANISM AND MAY
DAMAGE THE DOOR.

OPTIONAL THREE FUNCTION DELUXE WALL STATION
When the Wall Station is connected to the operator per instructions supplied with the wall station, it will provide the following
features:
1. “OFF-ON” will prevent inadvertent operation of the door from any other push button, radio or keyless entry device. It will also
as additional protection from unwanted operation during absence of the owner. This feature is to be activated only when the door is
at the full open or close position and never while the door is moving.
2. “LIGHT” button allows the convenience light to be turned on and stay on until turned off by a second push of the button or
activation of the door cycle.
3. “UP/DOWN” button provides normal opening and closing of the door by momentary activation of this push button. Function of
door cycle is described above - “How the Door Moves When the Opener is Activated”.

18
Adjustment #3: Setting Door Close Limit
Confirm trolley close position 9” to 10” between the inside face of the door
and the point where the door arm connects to the trolley (see illustration).
If adjustment of the close trolley position is necessary, activate the opener and
move the trolley 12” to 18” to provide access to the “Limit Stop” devices
(mounted on the chain). Move the limit stop to establish the correct trolley
close position as above.
Relocation of “Limit Stop” toward the door increases down travel.
Relocation of the limit stop away from the door reduces down travel. Note
that each chain link provides 1/2” adjustment of trolley travel. Cushion Arm

Adjustment #4: Obstruction Sensing (Closing Direction)
Your opener is designed to automatically reverse the door during closing travel
whenever it comes into contact with an object up to the last 1-1/2 inch of travel
above the floor. An object on the floor with a height of less than 1-1/2 inch will
cause the door to stop. (Test according to the instructions below.)
If the opener reverses properly with a 2” x 4” laid flat on the garage floor (as the test
below) and stops in the fully closed position, proceed to Adjustment #5.
If the door reverses when it comes into contact with the floor, move the close limit
stop, located on the left side (inside looking out, see figure Adjustment #1), towards
the power head unit. It is advised that you move the close limit stop one link at a
time and run opener through another close cycle, until the door stops when it comes
into contact with the floor.
When the door comes into contact with a 2” x 4” laid flat on the garage floor and stops intends of reversing, move the close limit stop
away from the power head unit. It is advised that you move the close limit stop one link at a time and run opener through another
close cycle, until the door reverses when it comes into contact with the 2” x 4”.

Adjustment #5: Alignment and Initial Test of Safe Finish Photosystem
A. Keep a portable transmitter with you to control the garage door opener. The red light on the receiver unit should now be on. If
not, recheck that the mounting screws are tight then, if necessary, align the photosystem by slightly bending the wall bracket
until proper operation is obtained.
B. Place an object (packing insert box or a similar object approximately six inches high) one foot in front of the transmitter or
receiver. The red LED should go OFF and remain OFF until the object is removed. NOTE: There may be a slight delay in
returning to normal depending upon how long the photosystem was blocked. If the light fails to go off when the object is placed
in the path of the beam check the wire connections and the installation height of the units (see Page 13).
C. Move to the center of the door. Make sure the red LED light is on. Move a solid object slowly through the beam. The
LED should go OFF and then ON.
D. Using the pushbutton or transmitter, activate the opener and check that it will operate through the full open and close cycles. If
not, re-align the photosystem by slightly bending the wall bracket until proper operation is obtained.
E. Tighten all mounting screws and bolts, loop and secure any extra wire.

Test Procedure
Place an object 6” x 12” on the floor (as illustrated)
progressively on foot from the left side of the door; center of
the door and one foot from the right side of the door. The
object must prevent an open door from closing in any other
mode other than constant pressure on the wall button. The
object should also cause a closing door stop and reverse to
the open position. If it doesn’t, the Safe Finish photoelectric
system must be adjusted lower and the test repeated until the
door responds properly to the 6” object.
If adjustments are needed, refer to preceding adjustment.
If the unit still will not respond and fails this obstruction
sensing beam test, the door may cause severe injury or death.
Have a qualified service person make repairs.
