-The Compressor requires a Digital Input for the Pressure Switch.
-The Set Relay for "braco" requires an enumerated constant, not a number. Enumerated constants evaluate to numbers but this is bad practice. This is why you see the red dot on the Set Relay, the .vi is basically doing implicit datatyping, i.e. it sees a datatype it doesn't expect but it can deal with it.
