IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING
SENSORS
The safety reversing sensors 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 efficiency 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
l
the door.
Sensors are facing each other with the lenses aligned and the
l
receiving sensor lens does not receive direct sunlight.
Sensors are no more than 6 inches (15 cm) above the floor
l
and the light beam is unobstructed.
