Penumantics confused LabVIEW

Hello, I am a rookie and was lost in why the compressor when I used an FRC example with a pressure sensor did not turn. I stop the compressor before it got higher than 80 PSI because I was afraid to go any higher. When does the compressor turn off. I am using LabIVEW to program. If someone could help me, that would be great thanks.

The compressor should run up to about 120 PSI. Then the switch should trigger and automatically turn off. Are you using the compressor hooked up to the PCM, or directly to the RoboRIO with a spike?
