9. Place an obstruction (ex. hand) between the IRB-4X transmitter and receiver. The red LED on the
receiver will turn on. Check the operator control board and verify that the safety input is recognized
by the operator. Test the beam with an obstruction between the transmitter and receiver
at multiple distances to confirm proper operation.
10. Remove the obstruction and red LED will turn off.
• If IRB-4X is aligned but not detecting an obstruction, consider slowly reducing
the sensitivity (clockwise) on the receiver until the obstruction is detected.
This may be applicable for installations with a detection zone of less than 20 ft.
• 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.
