I’m new to pneumatics and my controls team is trying to get a test system to run. We can’t figure out how to set up a pressure switch to shut off our compressor at 120 psi. I know 60 is our working pressure, but once our pressure reaches that, it keeps going. How do we program our pressure switch to shut our compressor off?
The pressure switch is preset for somewhere around 110 psi.
The pressure switch gets wired to a sidecar Digital Input, just where gets specified in your code.
The control PWM cable for the Spike controlling the compressor gets connected to a sidecar Relay output.
Here’s an example of the code:
