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.

It must be either:

A. Nason P/N SM-2B-115R/443 (wired as described) and/or

The 2 wires from the pressure switch must be connected directly to the pressure switch input of the PCM/PH controlling the compressor or, if controlled using the roboRIO and a relay, to the roboRIO. 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.

B. REV Robotics P/N REV-11-1107 (wired as described)

The analog output of the sensor must be connected directly to analog input 0 of the PH (with firmware version 22.0.2 or newer) controlling the compressor.

The REV Robotics Analog Pressure Sensor may only be used with PH compressor control and may not be used with PCM compressor control.
