Al, the main regulator may be left off the robot when using an off-board compressor with 60PSI tanks per R76-D.
Quote:
<R76> “Working” air pressure on the ROBOT must be no greater than 60psi. All working air must be provided through one primary Norgren adjustable pressure regulator.
...
D. If the compressor is not included on the ROBOT (under the provisions of Rule <R75>), the regulator may be located on-board or off-board, provided all other pneumatic rules are satisfied. Note that if the regulator is kept off-board the ROBOT with the compressor, then only low-pressure (60psi or less) “working” air can be stored on the ROBOT.

The pressure switch must be connected to the high pressure side of the system per R78. As the high pressure side of the system is not on the robot, it would seem that the pressure switch not only can be held off the robot, but must be if the main regulator is also held off the robot.

<R78> The Nason pressure switch 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. The two wires from the pressure switch must be connected directly to a digital input and ground port on the Digital Sidecar, and the cRIO-FRC 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.
