Re: Pressure Switch Not Working?
I can't comment on your code, but you can test if the switch closes at ~90 PSI and opens at ~120 with an ohmmeter.
Then verify (using code) that the DIO port is 'seeing' the switch change properly.
If it is, then make a program to command the compressor relay on and off, and see if you can get that to work. Pay attention to the LEDs at the DSC Relay ports.
If you do these 3 things, good chance you'll find the issue.
