• Patient airway (D) and manifold (E) pressures (transducers)
• Oxygen sensor (in breathing system)
• Inspiratory Flow Valve
• Gas Inlet Valve
• SCGO solenoid, SCGO/CGO position switches (if SCGO installed)
• Canister release switch
• ABS On switch
• ACGO position switch (if ACGO installed)
• O Flush switch
