SENSOR
The safety reversingsensormust be connectedand aligned
correctly before thegaragedooropenerwill movein the down
direction.
The sending sensor (with an amber LED)transmits an invisible
light beam to the receiving sensor (with a green LED). If an
obstruction breaks the light beam while the door is closing, the
door will stop and reverse to the full open position, and the
garage door opener lights will flash 10 times.
NOTE:For energy efficiency the garage door opener will enter
sleep mode when the door is fully closed. Thesleep mode shuts
the garage door opener down until activated. Thesleep mode is
sequenced with the garage door opener light bulb, as the light bulb
turns off the sensor LEDs will turn off and whenever the garage
door opener lights turn on the sensor LEDs will light. Thegarage
door opener will not go into the sleep mode until the garage door
opener has completed 5 cycles upon power up.
When installing the safety reversing sensors check the following:
• Sensors are installed inside the garage,one on either side of
the door.
• Sensors are facing each other with the lenses aligned and the
receiving sensor lens does not receive direct sunlight.
• Sensors are no more than 6 inches (15 cm) above the floor and
the light beam is unobstructed.
Be sure power is NOTconnected to the garage door opener
BEFORE installing the safety reversing sensor.
To prevent SERIOUSINJURY or DEATHfrom 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 floor.
