WIRE THE SENSORS
1. Separate the ends of the new sensor wire. Cut any exposed wire downto the
insulation.
2. Usingthe four locking connectors, connect the new wire to the existing wire by
color: white/black to white/black, white to white. NOTE: If installing in a pre-wired
garage, connect the new sensor wires to the same pre-installed wires as the old
sensors. Insert the wire allthe way into the connector. Firmly crimpthe connector
with adjustable pliers. Once crimped, the connector cannot be re-used.
Reconnect power to the garage door opener.
ALIGN THE SENSORS
IMPORTANT: The safety reversing sensors MUST be connected and aligned
correctly before the garage door opener will move in the down direction.
When the garage door opener has power, check the safety reversingsensors. If the
sensors are aligned andwired correctly, both LEDs will glow steadily.
To align the safety reversing sensors:
1. Loosen the wingnuts.
2. Adjust the sensors upor downuntilboth LEDs glow steady indicatingalignment.
3. Tighten the wingnut to secure the sensor.
TROUBLESHOOTING
If either of the sensor LEDs are off, there is no power to the sensor:
1. Check that you have power to the garage door opener.
2. Check the sensor wire is not shorted or broken.
3. Check that the sensors are wired correctly; white wires to white terminal and
white/black wires to grey terminal.
If the green receiving sensor LED is blinking, the sensors are obstructed or
misaligned:
1. Check for obstructions inthe sensor light beam.
2. Alignthe sensors.
3. If the receiving sensor (green LED) faces direct sunlight, switch the sensors to
opposite sides of the door toassure proper operation.
TEST THE SENSORS
Without a properly installed safety reversingsensor, persons (particularly small
children) couldbe SERIOUSLY INJURED or KILLED by a closinggarage door.
1. Open the door. Place the garage door opener cartonin the path of the door.
2. Press the remote control push button to close the door. The door will not move more
than 1"(2.5cm), the garage door opener lights willflash 10times, the green LED on
the receiving sensor will blink.
The garage door opener will not close froma remote controlif the sensor light beam is
misaligned or obstructed. If the garage door opener closes the door when the safety
reversingsensor is obstructed (andthe sensors are no more than 6"[15cm] above the
floor), callfor a trained door systems technician.

TEST THE SAFETY REVERSAL SYSTEM
Without a properly installed safety reversal system, persons (particularly small
children) couldbe SERIOUSLY INJURED or KILLED by a closinggarage door.
• Safety reversal system MUST be tested every month.
• After ANY adjustments are made, the safety reversal system MUST be tested.
Door MUST reverse oncontact with1-1/2" (3.8 cm) high object (or 2x4 laidflat)
on the floor.
1. Withthe door fully open, place a 1-1/2inch (3.8 cm) board (or a 2x4 laidflat) onthe
floor, centered under the garage door.
2. Press the remote controlor wall-mounted door controlto close the door. The door
shouldstopand reverse when it makes contact withthe board. The door returns to
the previous open position. Newer model openers will beep andthe lights willflash 5
times to indicate reversal.
3. If the door reverses, remove the board. The test is complete.
If the door stops but does not reverse:
1. Refer to your garage door opener manual andset the down limit closer to the
garage floor. NOTE: On a sectional door, make sure adjustments do not force the
door arm beyond a straight up and down position.
2. Repeat the Safety Reversal test.
If the test continues to fail, calla trained door systems technician.
