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
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 20.
