2. If closing, the door will reverse.
3. If opening, the door will stop.
4. If the door has been stopped in a partially open
position, it will close.
5. If obstructed while closing, the door will reverse. If the
obstruction interrupts the sensor beam, the opener
lights will blink for fi ve seconds.
6. If obstructed while opening, the door will stop.
7. If fully open, the door will not close when the beam is
broken. The sensor has no effect in the opening cycle.
If the sensor is not installed, or is misaligned, the door
won’t close from a hand-held remote. However, you can
close the door with the door control, the Outside Keylock,
or Keyless Entry, if you activate them until down travel
is complete. If you release them too soon, the door will
reverse.

conditions: when the opener is initially plugged in; when
power is restored after interruption; when the opener is
activated.
They will turn off automatically after 4-1/2 minutes or
