INSTALL ONE SET OF LIGHT CURTAINS
The mounting brackets must be securely fastened to a solid surface such as a wall framing. If installing the mounting brackets in masonry construction,
add a piece of wood at each location to avoid drilling extra holes in the masonry. NOTE: If the Light Curtain is installed with coil cord, the coil cord needs
to be secured so it will not interrupt the light beams.
1. Fasten the mounting brackets loosely to both Light Curtains with the screws provided.
2. Measure a minimum of 12 inches above the photoelectric sensors. Mark this location. The Light Curtain must be installed above this point.
3. Hold the Light Curtain up to the desired mounting location with the cable end pointing upward. Secure the bottom mounting bracket to the mounting
surface.
4. Make sure the Light Curtain is level and secure the upper mounting bracket to the mounting surface.
5. Tighten the screws to secure the Light Curtain to the mounting bracket.
6. Secure the other Light Curtain to the opposite side of the door following steps 2 - 5, making sure they are aligned.
7. Run wires to the operator.
8. Twist like colored wires together, brown to brown and blue to blue.
To prevent possible product damage and incorrect operation:
• NEVER scratch or paint the optical sensors.
• DO NOT drill ANY additional holes into the Light Curtain.
• Correctly connect and align the Light Curtain transmitter and receiver.
• DO NOT bend or twist the Light Curtain.
• Oil may damage the Light Curtain cable so contamination MUST be
avoided at ALL times.
• DO NOT mount the Light Curtain where sunlight or other external
infrared light sources will shine directly into the optical sensors of the
Light Curtain receiver. If necessary, switch the mounting side of the
Light Curtain transmitter and receiver.
INSTALLATION
INSTALL TWO SETS OF LIGHT CURTAINS ON THE SAME DOOR
Installing two sets of light curtains on the same door is recommended for high volume vehicle traffi c.
1. Install the fi rst set of Light Curtains on the door as described in the Install One Set of Light Curtains section.
2. Install the second set of Light Curtains above the fi rst set. The black and white wires are wired in parallel and the blue and brown wires are wired in
