R812       *Pressure switch requirements. The 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.

R808       *Working air pressure limit. Working air pressure (air pressure used to actuate devices) on the ROBOT must be no greater than 60.0psi (413.7kPa, 4.137Bar) and must be provided through a single primary adjustable, relieving, pressure regulator. Additional regulators may be located downstream of the single primary regulator.

R813       *Vent plug requirements. Any pressure vent plug must be:

R809       *Limited devices at high pressure. Only the compressor, relief valve, pressure switch, pressure vent plug, pressure gauge, storage tanks, tubing, pressure transducers, filters, and connecting fittings may be in the high-pressure pneumatic circuit upstream from the regulator.
