position, it will close.
5. If obstructed while closing, the door will reverse.

The sensor has no effect in the opening cycle.
If the sensor is not installed, or is not aligned correctly,
the door won't close from any remote control
transmitter. You can close the door with the Door
Control, the Outside Keylock, or Keyless Entry,
however, if you activate them until down travel is
complete. If you release them too soon, the door will
reverse.
The opener lights will
blink for 5 seconds
when the
safety reversing sensor causes the door to reverse.
Opener Lights will turn on under the following
conditions: When the opener is initially plugged in;
when the power is interrupted; when the opener is
activated. They will turn off automatically after 4-1/2
minutes or provide constant light when the Light
feature is activated. Bulb size is 75 watts maximum.
The lockout feature
prevents the trolley from
reconnecting automatically.
Pull the manual release
handle down and back
(toward the opener). The
door can then be raised
and lowered manually as
often as necessary. To
disengage the lockout
feature, pull the manual
release handle straight
down. The trolley will
reconnect on the next UP
or DOWN operation.
