WIRING THE SAFETY REVERSING SENSORS
TROUBLESHOOTING THE SAFETY
REVERSING SENSORS
1. If the
sending eye
indicator LEDs are both flashing
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.
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
and the LED indicator light will flash 10 times. See
page 21.
