I am assuming that you are using the photoelectric sensor that came in the kit, although other will be very similiar.

If connecting it to the DIO does not help - then check your wires

This wire will get attached to the Power Distribution Board
Brown is positive - so connect it to a red power wire
Blue is negative - so connect it to a black power wire

Now check your PWM cable
take the black wire and connect it to the white wire on a PWM cable, and attach it to your DIO - you pick a slot

You can also check to see if the sensor is working because the light will change color, you can adjust the sensitivity by using a small screwdriver
