IRB-4X Receiver connections (figure 2) Detect LED
1. Terminal output connections from left to right are:
Normally closed, Common, Normally open, Power, Power
2. Connect power (12 – 24V AC/DC to Power input terminals (no polarity)
3. Connect the Common to the operator control terminal per manufacturer
4. Connect either the Normally open or Normally closed as needed to the
Control terminal specified by the operator manufacturer.
5. The Power LED will glow green when powered.
6. Adjust sensitivity potentiometer as needed by turning counter clockwise
to increase gain. (range is 25 to 115 feet). (see arrow)
7. The detect Led will glow red when an obstruction occurs.
8. On some variable frequency drives and noisy installations, it may
be necessary to connect the bottom right mounting hole labeled
“Earth Ground” to a wire connected to earth ground.
* Do not connect unless necessary
9. Use minimum gain setting needed to achieve reliable detection. Power LED
Installation and Mounting Instructions
1. Mount to operator manufacturer and local ordinance requirements.
2. Remove grey front cover by removing (4) plastic retaining screws
3. Drill (4) mounting holes in surface of IRB-4X mounting location.
