OPERATION
ALIGNING THE SAFETY SENSORS
See Figure 57.
WARNING:
DO NOT operate the garage door opener unless the
safety sensors are installed and working correctly. Failure
to properly install and ensure that the safety sensors are
working correctly can result in death or serious personal
injury.
WARNING:
The effectiveness of the safety sensors included in this
system directly relates to the placement and installation
of the sensors. Incorrect placement or installation could
prevent the sensors from working as intended and result
in death or serious personal injury.
NOTICE:
The garage door will not close unless the safety sensors
are installed, wired, and aligned correctly.
Install and wire the safety sensors as described earlier in
the Installation section.

LED
Connect the garage door opener to an AC power supply.
NOTE: Make sure the power supply is normal household
voltage, 120 volts, AC only, 60 Hz
If wired correctly, the LED lights on both sensors should
shine continuously. If the LEDs do not come on, unplug
the garage door opener and ensure that the sensors are
wired correctly. If problem persists, refer to the Safety
Sensor Diagnostic Feedback chart later in the manual.
If the LED lights on both sensors shine continuously, then
the sensors are aligned and no adjustments are needed.
If the LED lights are blinking, then the sensors need to
be aligned.
Loosen, but do not remove, the fasteners securing the
sensors in place and adjust the position of the sensors
until the lens on the source and receiver are directly facing
one another.
When the sensor lenses are in the correct position, the
invisible light beam emitted by the source will be captured
by the receiver and the LEDs will shine continuously.
NOTE: If an object crosses the path of the beam, an open
garage door will not close and a closing garage door
should stop and reverse to the fully open position.
After the sensors have been aligned, retighten fasteners.
