Thanks all for the replies!
I got it to work! But there were some other details that were needed to get it running. Would the below be a correct guide?
*PWM cables come in different colors but work the same, the darkest is the ground, positive is the middle and signal is the remaining one.
-Attach a PWM (3 pin) connector to Relay 1 on the Digital Side Car and connect the other end to the Spike-Relay, with the black wire on the furthest right of the slot.
-Attach another PWM(3 pin), but only the Ground (black) and signal (white) to the Pressure detection valve you should have put in place next to the pressure release valve. There should be signs G(B) for ground and signal for the other. And then connect the other end of the PWM to slot one of the Digital I/O slots, (Right above relay slots)
-Make sure M+ and M- are going to the Air compressor, 12v and G(B) are going the over way. Just wire the positive/negative correspondingly across to how the air compressor is wired.
* Wire the 12V and G(B) side to a 20-amp Snap-Action breaker on the Power Distribution Board.
-Make
sure that you add the correct programming in Labview, here is mine.
Begin.vi:
Teleop.vi:
Periodic Tasks.vi: (Make sure it's outside of any loops)
With this setup, when you enable your robot in Teleop, it then starts the air compressor and automatically shuts off after 117 PSI. You can set this up to start when your robot initializes if you just put the "enable" node in the Begin.vi right after the registry set node.
