Is there any resource out there for pnuematics code? I don’t quite understand how the pressure switches work, but the pnuematics manual doesn’t mention any pinouts or where to wire the switches.
Do a quick search of the forums, it will bring up many threads.
The pressure switch is a digital input that should be shown how to wire a digital input in the manual for the control system, you can pick the input. We had no pnuematics last year but I think it was adjustable for the pressure that will trip it. Then you can Turn on/off the compressor based on the switch or two switches (one for high, one for low) I think there are also a few white papers on Compressor programming
Check this white paper on the sixth page of white papers for an example

The pressure switches are like any standard digital input. There’s no + or -, no specific way to wire it or hook the tubing up for the pneumatics.
When it needs to be filled, the pressure switch will be closed, it will show up as a 1 in programming (current).
When it is filled, the pressure switch is open, which is a 0 in programming (no current).
The rubber stopper on top is removable. Underneath it is a screw that can be adjusted. Tightening (clockwise) will raise the tripping pressure. Loosening the screw (counter-clockwise) will lower the pressure.
I realized that one page didn’t print when I printed out the control manual - the page with ports and pin-outs for switches. Thanks for your help anyway
