You didn't say whether you tried unplugging the PWM cable to see if it stopped blinking, so I'm still not convinced that you don't have a wiring problem....
However, the black slot on the front IS the Callibrate adjustment, so you use this to set the sensor for your field. (I've not heard of a LEARN mode for this sensor.... but who knows).
Once you stop the flashing, Calibration is pretty simple. Put the sensor over the carpet. Turning the screw all one way should make the LED go green (this is the LEAST SENSITIVE setting).
Now position the sensor over the tape. Slowly turn the screw the other way until the LED switches to Orange. Turn it a little further, and then move the sensor over the carpet again, it should go back to green.
It may take some tweaking but you want to ensure that the LED is green over the carpet, and orange over the tape.
Note : My experience is that most students assume that "looking correct" IS "correct". I don't always track down credentials before answering a post, but base my reply on what's written. Sorry.

The power is the same for all of the photoswitches coming from the Power Distribution Board. The white wire from the photoswitch is connected to the white signal wire on the PWM.
I was wondering if people knew anything about the teach mode because I was trying to find the calibration screw and turned the front black piece. Now when I turn it on it is always flashing between the yellow and the orange lights.
