Connect to garage door opener:
• Strip 7/16" (11 mm) of insulation from each set of
wires. Separate white and white/black wires suffi ciently
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 10).
TROUBLESHOOTING THE SAFETY REVERSING
SENSORS
1. If the
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.
2. If the
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
.
3. If the
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 15.
Figure 10
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 fl ickering (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.
