2-1.   Unpack the tube and identify which stick is the Emitter (2  

wires) and which is the Receiver (4 wires). The Receiver  

typically mounts on the same side as the operator.

2-2.   Identify the preferred location, usually close to the door 

tracks on the inside of the door opening.

2-3.   Attach the brackets to any available mounting points, using 

the screws provided or other appropriate hardware.  One 

bracket should go approximately 6” below the top and another 

6”above the bottom of the sticks.  For the 6-foot sticks, an 

additional bracket should be added in the middle.

2-4.   Make sure the brackets are all in-line. The functional 

operating distance between Emitter and Receiver is 

between 6 feet and 33 feet.

2-5.   Press the sticks into the brackets. The flat surface should 

be facing across the door opening so that the sticks are 

pointing at each other and the bottoms are resting on the floor.

2-6.    Wire the sticks to the operator. A total of six (6) wires need to 

connect at the operator, 2 run from the Emitter and 4 from the 

Receiver. The black and red wires from both sticks will connect 

to the accessory power (usually 24VAC or 12VDC).  The 

Green and White wires will connect to the photo-eye input (ex: 

LMEP & Common). 

Refer to the electrical connection diagram.

2-7.   Note that only one device can be connected to the photo-eye    

input on the operator.      

2-8.   Confirm that the Green LED is ON at the bottom of both sticks.

2-9.   The Red LED on the receiver indicates either an obstruction or 

a mis-alignment.  The light curtains have a wide acceptance 

angle and should align easily.  Test proper operation of the 

sticks by standing in the opening and observing the Red LED

turning ON.

2-10. Test for proper operation with the operator and door.

Installation

The MLC-K36/K72 Light Curtain is a UL approved light curtain that can be used in place of a monitored photo-eye.

It provides additional protection for the area above the floor, protecting people and vehicles more effectively than

a single-beam eye.
