• Center each sensor unit in a "C" wrap with lenses
pointing toward each other across the door (see
Figure 7).
• Secure sensors with the hardware shown. Finger
tighten the wing nut on the
receiving eye
to allow
for final adjustment. Securely tighten the
sending
eye
wing nut.
• Run the wires from both sensors to the opener.
Use insulated staples to secure the wire to wall
and ceiling.
• Strip 1/4" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener terminal screws:
white to 2 and white/black to 3.
• Plug in the opener. Make sure the Lock Feature is
off
. Green indicator lights in both the sending and
receiving eyes will
glow steadily
if wiring
connections and alignment are correct.
If the indicator light is
off
in the
receiving eye
(and
the invisible light beam path is not obstructed),
alignment is required.
• Loosen the receiving eye wing nut to allow slight
rotation of unit. Adjust sensor vertically and/or
horizontally until the green indicator light
glows
with a steady light
.
• When indicator lights are
glowing steadily
in both
units, tighten the wing nut in the receiving eye unit.
