Align the Safety Beam Sensor

If the receiver LED is off,
dim, or flickering (while the
invisible light beam path is
not obstructed), alignment
is required.
Receiving
Sensor
(Green LED)
Green Light:
On – Beam Aligned, No Obstructions
Off – Beam Not Aligned Or Obstruction - Sensors Need Alignment
Dim / Flickering – Sensors Need Alignment
If the green LED on the receiving unit is on steadily, your
safety sensors are aligned properly. If the green LED is
flashing or off, loosen the wing nut on the receiving unit,
adjust the angle until the green LED is on steadily, then
tighten the wing nut.

Testing with Obstruction
With the sensors properly aligned, place an obstacle in
the path of the beam. The transmitting sensor red LED
should be on, the receiving sensor green LED should be
off. Remove the obstacle, both LEDs should be on steadily.
Note:
Be sure to stay out of the beam's path while aligning
Note:
If the transmitting sensor LED does not glow steadily, check the following:
I. Power to the Opener is connected
II. A short in the white or white/red wires (from wire holders or at the openers terminals)
III. Incorrect wiring between sensors and opener
IV. A broken wire
If the transmitting sensor LED glows steadily but the receiving sensor LED doesn't glow:
I. Check alignment
II. Check for an open wire to the receiving sensor
III. Check for dirt on lens, or sun shinning into lens

Indicator LED
Loosen/Tighten this Wing
Nut to align the sensors
Plug in the opener. The receiving sensor
indicator LED (green color) should glow
steadily if the wiring and alignment are
correct. The transmitting sensor indicator
LED (red color) will glow steadily regardless
of alignment or obstruction.
Loosen the wing nut on the transmitting sensor (with
RED LED on) and adjust the angle so it points toward
the receiving unit.
