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.
