TROUBLESHOOTING THE SAFETY REVERSING SENSORS
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 safety reversing sensors and opener.
• A broken wire.
If the
sending eye
indicator light
glows steadily
but the
receiving eye
indicator light
doesn't:
• Check a lignment.
• Check for an open wire to the receiving eye.
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 remote lights will blink 10 times. (If bulbs are not installed, 10 clicks can be
heard.) See page 15.
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 the safety reversing sensor until it
receives the sender’s beam. When the green indicator light
glows steadily
, tighten the
wing nut.
