IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING
SENSOR
The safety reversing sensor must be connected and aligned
correctly before the garage door opener will move in 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 effi ciency the garage door opener will enter
sleep mode when the door is fully closed. The sleep mode shuts
the garage door opener down until activated. The sleep 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. The garage
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.
