Brown +

White (sig) to digital side car
Black nothing
If the Sensor is Green: Sensor is powered but does not sense reflection. no output on blk or wht.
If sensor is Orange: ON sensor is recieving at least 2.5 times the signal strength needed to trigger an output and green will turn off. May have to adjust the sensitivity adjustment on top of the sensor to get an orange on if already mounted. Do this by placing over reflective surface and adjust until it comes on. Sensitivity is the screw on top. If orange is not on there will be no output on blk or wht.
If sensor is Yellow: the output has been energized meaning it sensed a reflective object. be careful most bright objects can be sensed regardless of color.
Typical sensor indication is the following
Green ON, Orange OFF, Yellow OFF over dull none reflective surface wht low and blk high
Green OFF, Orange ON and Yellow ON over bright reflective surface wht high and blk low
If you have a flashing LEDs, the sensor has gone in to short circuit protection mode becasue one of the outputs is shorted to ground or it is not wired up correctly. Make sure the black wire is not connected ianything. Make sure the white is connected to the signal pin on the digital side car pwm input and not the + or -. Best way to prevent the shorting out of the black wire is to clip the stripped wire and then wrap it with electrical tape. Inspect the sensor cable for any nicks. I will try and post a quick video by the end of today to show how it works and how to connect it.
