pneumatics module/robot inspection

[Al Skierkiewicz]

R88 The pressure switch requirements are:
A. It must be Nason P/N: SM-2B-115R/443
B. It must be connected to the high-pressure side of the pneumatic circuit (i.e. prior to the pressure regulator) to sense the “stored” pressure of the circuit.
C. The two wires from the pressure switch must be connected directly to the pressure switch input of the PCM controlling the compressor or, if controlled using the roboRIO and a Spike relay, to the roboRIO.
D. If connected to the roboRIO, the roboRIO must be programmed to sense the state of the switch and operate the relay module that powers the compressor to prevent over-pressuring the system.

The PCM is by far the easier method. If you don't use one, you do have to use a Spike Relay for compressor control. You may replace the 20 amp fuse with a 20 amp breaker for this application only. All other motors must only use the 20 amp fuse.
