MOUNTING AND WIRING THE SAFETY
REVERSING SENSORS
•
Run the wires from both safety reversing sensors to the
operator. Use insulated staples to secure wire to wall
and ceiling.
• Strip 11mm (7/16") of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the operator quick-connect terminals: white to
white and white/black to grey (Figure 6).
TROUBLESHOOTING THE SAFETY
REVERSING SENSORS
1. If the
sending eye indicator LEDs are both blinking
after installation, check for:
• Electric power to the operator.
• A short in the white or white/black wires. These can
occur at staples, or at operator connections.
• Incorrect wiring between safety reversing sensors and
operator.
• 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.
