MOUNTING AND WIRING
THE SAFETY REVERSING SENSORS
Slide a 1/4"-20x1/2" carriage bolt head into the slot on each
•
sensor. Use wing nuts to fasten sensors to brackets, with
lenses pointing toward each other across the door. Be sure the
lens is not obstructed by a bracket extension (Figure 5).
Finger tighten the wing nuts.
•
Run the wires from both sensors to the opener. Use insulated
•
staples to secure wire to wall and ceiling.
Strip 7/16" (11 mm) of insulation from each set of wires.
•
Separate white and white/black wires sufficiently to connect to
the opener quick-connect terminals. Twist like colored wires
together. Insert wires into quick-connect holes: white to white
and white/black to grey (Figure 6).
ALIGNING THE SAFETY REVERSING SENSORS
Plug in the opener. The indicator lights in both the
•
sending
and
receiving eyes
will
glow
steadily
if wiring connections and
alignment are correct.
The
sending
eye amber indicator light will glow regardless of
alignment or obstruction. If the green indicator light in the
receiving eye
is
off, dim, or flickering (and the invisible light
beam path is not
obstructed), alignment is required.
Loosen the
•
sending
eye
wing nut and readjust, aiming directly
at the
receiving
eye.
Lock in place.
Loosen the
•
receiving
eye
wing nut and adjust sensor until it
receives the sender’s beam. When the green indicator light
glows steadily
, tighten the wing nut.
TROUBLESHOOTING THE SAFETY REVERSING SENSORS
If the
1.
sending eye
indicator light does not
glow steadily
after
installation, check for:
Electric power to the opener.
•
A short in the white or white/black wires. These can occur
•
at staples, or at opener connections.
Incorrect wiring between sensors and opener.
•
A broken wire.
•
If the
2.
sending
eye
indicator light
glows steadily
but the
receiving
eye
indicator light doesn't:
Check alignment.
•
Check for an open wire to the
•
receiving
eye
.
If the
3.
receiving
eye
indicator light is dim, realign either sensor.
NOTE:
When the invisible beam path is obstructed or misaligned
while the door is closing, the door will reverse. If the door is
already open, it will not close. The opener lights will blink 10
times. See page 20.
