Wiring pressure switch

Careful. The pressure switch is not rated to 12 volts, so it must be wired through the robot controller.

2008 Manual <R96> 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
terminal on the Robot Controller, and the controller must be programmed to sense the state
of the switch and operate the relay module that powers the compressor.

Last year's manual gives more detail:

2007 Manual <R103> The Nason pressure switch must be connected to the output end of one of the Clippard
tanks to sense the tank’s pressure. The two wires from the pressure switch must be
connected directly to a digital input and ground terminal on the Robot Controller, and the
controller must be programmed to sense the state of the switch and operate the relay
module that powers the compressor. The Parker pressure vent valve must be connected to
a Clippard tank such that, when manually operated, it will vent to the atmosphere to relieve
any stored pressure. The valve must be placed on the ROBOT so that it is visible and
accessible.
