The Pneumatic Unit regulates the pressurized air coming from an external compressed air source. It includes an activation switch to quickly turn on or off the air supplied, an adjustable low-range pressure regulator (0 to 200 kPa (0 to 30 psi)) with its output air port, and an adjustable high-range pressure regulator (0 to 700 kPa (0 to 100 psi)) with its output air port. A fault panel is included to insert a fault in the system when performing troubleshooting exercises.
