Programming the Air Compressor and Pressure Switch

If there is no light on the DSC relay channel the spike isn't malfunctioning (not yet at least).

How is your pressure switch wired?

You should have a signal wire and ground wire going to the switch. This cable should plug into a digital I/O port on the DSC.
See the wires on the pressure switch in this figure

1. put together a test project in RobotBuilder that has one subsystem, one relay output (where the compressor is) and one digital input (where the switch is).
2. Load the project into the robot.
3. Put the robot into test mode
4. Go into the livewindow and manually try to turn the compressor on.
5. If the compressor doesn't fire up, you've got data flow or power problem; if the compressor fires up, you know your wiring is good.
