CABLE TENSION SENSOR ASSEMBLY AND INSTALLATION INSTRUCTIONS
NOTE: Left hand assembly shown, for right hand assembly,
orientation will be opposite.
1. Introduce cable slack on the side of the door where the
CTS will be installed (Left side of door from inside of garage
looking out for left hand unit and right side of door for right
hand unit).
2. Use a 5/32” alan wrench to remove the socket head cap
screw from the pivot arm assembly. Place the pivot arm
assembly around the torsion shaft as shown, reinstall the
socket head cap screw and tighten.
3. Slide the pivot arm towards the cable drum and feed the
door cable over the front side of the pivot arm roller. Place
the assembly against the side of the drum.
4. Use a 3/16” alan wrench to remove the socket head cap
screws from the split shaft collar. Place the collar
around the torsion shaft and reinstall screws. Do not tighten.
5. Slide the collar towards the pivot arm and touch the side of
the pivot arm lightly. Tighten the screws in the collar.
NOTE: Make sure that the pivot arm is free to rotate after
the collar is tightened. The collar must hold the pivot
arm as close as possible to the cable drum, however, not
so tightly that the arm is not free to rotate on the torsion
shaft.
6. Place the CTS assembly into position. Make sure
that the roll pin on the pivot arm extends through the angled
slot on the CTS. Rotate pivot arm down towards header side
of the angled slot. With the roller on the CTS over the front
side of the door cable and the assembly in position, mark the
location of the 5 CTS assembly mounting holes and then
remove the assembly.
NOTE: Measure the distance from the center of the torsion
shaft to the header where the CTS will be mounted. The
optimum distance is 2-3/4”. If your measurement is
more than the 2-3/4” the CTS must have a backer
installed to make up the difference.
EXAMPLE: If you measure 2-7/8” you will need a 1/8” thick
backer. If you measure 3” you will need to install a 1/4”
thick backer, etc. Repeat step 6 if a backer was installed.
7. Drill pilot holes for the 5 CTS lag bolt mounting screws.
To prevent possible SERIOUS INJURY OR DEATH,
SECURELY mount the operator for proper operation
of the Cable Tension Sensor Assembly.
WARNING
CAUTION
WARNING

8. Reinstall the CTS and attach to the header using the 1/4” x
1” lag screw provided.
NOTE: If it is necessary to use longer screws, due to
backer or other conditions, to securely fasten the
assembly, obtain them at local hardware store. 1/4”is
the required size.
9. Rotate the pivot arm out away from the header. Maintain the
pivot arm in this position. Rotate the torsion spring counter
clockwise and place the end of the spring beneath the pivot
arm roll pin.
NOTE: Make sure that the other leg of the spring hooks
onto the tab extending from the CTS as shown. (Had this
been a right hand assembly, the spring would have been
rotated clockwise as viewed.)
10. You may now remove the slack that was introduced into the
door cable.
11. Attach the door stopper bracket to the CTS by removing
the 2 mounting screws with a 5/16” wrench. The bracket can
be mounted with the long leg or the short leg attached to the
CTS. This will depend on the distance from the CTS to the
top of the top door section. Tighten the 2 mounting screws.
Apply the self adhesive bumpers supplied to the bottom side
of the door stopper bracket.
12. Try to raise the door manually and check to make sure that
the door stopper bracket contacts the top of the top door
section when this is done. Loosen, adjust and relighten as
needed to accomplish this.
13. Wire the common and the normally open contacts of the
CTS switch in series with one of the wires from the receiving
photo eye. Flag style terminals have been provided to make
your connections. Refer to the wiring diagram in the back of
the owner’s manual.

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 SENSORS
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 indi-
cator 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 operator light will flash 10 times.
The photo eyes must be installed inside the garage so that
the sending and receiving eyes face each other across the
door, no higher than 6" above the floor.
Either can be installed on the left or the 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.
THE PROTECTOR SYSTEM
If it is necessary to mount the units on the wall, the brack-
ets must be securely fastened to a solid surface such as
the wall frame. Extension brackets are available if need-
ed. 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.

INSTALL THE PROTECTOR SYSTEM
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” above the floor.
They may be installed in one of three ways, as follows.
Garage door track installation (preferred):
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 flush, with the lip hugging the back edge of
the track, as shown in figure 9.
If your door track will not support the bracket securely,
wall installation is recommended.
Wall Installation:
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
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" above the
floor.
Attach the 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:
Use wood blocks or extension brackets (see
accessories) to elevate sensor brackets so the lenses
will be no higher than 6" above the floor.
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 floor with concrete anchors as shown.

INSTALL THE PROTECTOR SYSTEM (CON’T)
MOUNTING AND WIRING THE SAFETY SENSORS
Slide a ¼"-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. See Figure 12
Finger tighten the wing nuts.
Run the wires from both sensors to the opener. Use
included staples to secure wire to wall and ceiling.
NOTE: One wire from receiving eye must be cut and
connected to the cable tension sensor switch common
and normally open terminals using the flag connectors
provided. See wiring diagram on page 21.
Feed the wires from the IR’s and CTS through the
same bushing as the door control wires on the
operator.
Strip ¼" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener terminal screws: white to IR
white and white/black to IR white/black.
FIGURE 12
FIGURE 13
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 regard-
less 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), align-
ment 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 senders beam. When the green
indicator light glows steadily, tighten the wing nut.
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 operator light will blink 10 times. See page 13.

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.

FORCE ADJUSTMENTS
The open/down force adjustments are made by adjusting
two control knobs inside the operator end panel. One
knob controls the drive force adjustment. The second
knob controls the sensitivity, which is the change of force
as seen by the operator.
To set the forces
1. Adjust the drive force to minimum and the sensitivity
to minimum.
2. Increase the drive force in 10 degree increments until
the door travels freely from limit to limit.
3. Increase the sensitivity in 10 degree increments until
the door begins to reverse/stop in mid-travel.
4. Decrease the sensitivity by a 10 degrees and run the
door through a complete cycle to confirm normal opera-
tion. Refer to figure 17.
If the door stops normal travel of open/close to the limits,
decrease the drive and sensitivity knobs to minimum and
repeat steps 2 through 4.
DRIVE FORCE SENSITIVITY
FIGURE 17
Without a properly installed safety reversal system, per-
sons (particularly small children) could be SERIOUS-
LY 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 the floor.

How and When to Adjust the Forces
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
page 19. If the door is hard to hold or doesn’t reverse,
decrease the drive force by turning the control counter-
clockwise.
Make 10 degree turn adjustments until the door revers-
es normally. After each adjustment, run the opener
through a complete cycle.
Test the UP (open) force:
Grasp the door bottom when the door is about halfway
though UP (open) travel. The door should stop. If the
door is hard to hold or doesn’t stop, decrease drive
force by turning the control counterclockwise.
Make 10 degree turn adjustments until the door stops
easily. After each adjustment, run the opener through a
complete travel cycle.
If the door doesn’t open at least 5 feet:
Increase drive force by turning the control clockwise.
Make 10 degree turn adjustments until door opens
completely. Re-adjust the UP limit if necessary. After
each adjustment, run the opener through a complete
travel cycle.
If the door reverses during the down (close) cycle
and the opener light isn’t flashing:
Increase drive force by turning the control clockwise.
Make 10 degree turn adjustments until the door com-
pletes 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.
NOTE: If you open/close too many times, the motor
will stop due to thermal override cut off.

TEST THE SAFETY REVERSE 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.
WARNING
CAUTION
WARNING
WARNING
Test:
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.
Adjustment:
If the door
stops on the obstruction, it is not traveling
far enough in the down direction.
1. Increase the DOWN limit by turning the DOWN limit
nut away from the switch one notch at a time see
page 16.
2. Repeat the test.
Make sure limit adjustments do not force the door
down and introduce cable slack.
3. When the door reverses on the one-inch object (or
2x4 laid flat), remove the obstruction and run the
opener through 3 or 4 complete travel cycles to test
adjustment.
If the door will not reverse after repeated
adjustment attempts, call for professional garage
door service.
Important Safety Check
Repeat Adjustment Steps 1, 2 and 3 after:
Each adjustment of force controls or limit 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.

TEST THE PROTECTOR SYSTEM
Press the door control to open the door.
Place the opener carton in the path of the door.
Press the door control to close the door. The door
will not move more than an inch, and the opener
light will flash 10 times.
Professional service is required if the opener
closes the door when the safety reversing sensor
is obstructed.
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.
The garage door can be closed by pressing and
holding the door control button until down travel is
completed.
Without a properly installed working safety reversing
sensor, persons (particulary children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
