SAFETY TEST:
Photo eye sensors installed on opposite sides of your door opening
are intended to detect a person or object in the path of the door
and prevent the door from moving downward. The following steps
will determine if the system is functioning properly:
Open door using the operator’s transmitter or wall control.
Place a box or other object in the path of the door so it breaks
the photo eye beam. See Fig. 38A. Red indicator light on
receiver should go out.

PHOTO EYE SENSORS ALIGNMENT:
The photo eye sensors maintain an invisible, unbroken beam
between each other. See Fig. 38.
NOTE: Sensor alignment must be done with the door in the closed
position in order to ensure proper visibility of the sensor
indicator
LED.
When the photo eye system is connected to the operator
and the power is on, the green light on the transmitter sensor
flashes, if the sensors are not aligned. When the sensors are
aligned, the green light on the transmitter sensor will turn
steady. See Fig. 38.
Sensors must be installed parallel to the door plane and make
sure the sensors are facing each other.
Press and release the wall control button. The door should
not move in the down direction. LED# 7 and #8 on the
operator will flash. If this does not happen, disconnect
operator and call for service.
To reset operator, remove the obstruction and operate the
door normally.
If photo eye sensors are not aligned or are damaged, door
can only be closed by pressing and holding wall control
button until door is fully closed.

The safety reversal function of your operator is an extremely
important feature of your operator. Testing this function ensures the
correct operation of your operator and door.
The reversal system test should be performed:
Once per month.
Anytime the travel or force limits are reset or changed.
Place a 1-1/2" high rigid object (or a 2x4 board laid flat)
on the floor directly in the path of the door. See Fig. 36.
S
tart the door in the downward direction and watch what happens.
When door contacts the object (or 2x4), it should stop,
reverse, and automatically return to the fully opened position.
If the door does not reverse, reset the down travel limit
so that the door travels slightly further down in the closed
direction. Then, retest the unit as described above.
If the door still does not reverse, disconnect your operator
and call a service person.
Once the adjustments have been set and the door has
been run up and down twice uninterrupted for the
operator to “learn” the new settings, you must test the
reversal system for proper operation.

CONNECTING WIRES TO THE PHOTO EYE SENSORS
SUPPLIED WITH SEPARATE WIRE BUNDLE AND PREWIRED
GARAGES (if required). Fig. 25
Separate 2” of the double wire from each photo eye sensor into
two single wires.
C
onnect the solid color (white) wires leads from each sensor together
with the wire (white) leads to operator quick-connect terminals. Repeat
the same procedure for the sensors stripe wire (black / white). Use
the cable couplers shown in Fig. 25 for connections between sensor
wire and installation wires.
Run wires along the wall and the top of the rail assembly to the
operator. Use the three wire holders to secure wires.
See Fig. 25A.
MOUNTING THE PHOTO EYE SENSOR BRACKETS TO WALL:
Locate the mounting position for brackets (bracket can be
mounted in any position as long as photo eye beam will have a
clear path from one side of door to other side after mounting).
U
se the bracket mounting holes as a template to locate an drill (2)
3/16" diameter pilot holes on both sides of the garage door as shown
in Fig. 26.
S
ecure the bracket with 1/4" x 1-1/2" lag screws provided as shown
in Fig. 26.
MOUNTING THE PHOTO EYE SENSORS TO MOUNTING

Install the sensors to the mounting bracket by inserting bend
clips of sensor bracket through the vertical slot on mounting
bracket. See Fig. 27A.
I

bracket.
T
wist one of the straight clips slightly to lock the sensor in place
once inserted through vertical slot on the mounting bracket.
See Fig. 27B.
Repeat the above pr
ocedure for the other sensor.
