When switch is released, an input signal is sent to Node-1
controller. Node-7 controller sends a zero volt output to
hydraulic solenoids HS-72 and 73 to return valve to center
position.
Node-3 sends a variable voltage output to accessory system
proportional relief solenoid HS-68 to provide approximately
3,000 psi (207 bar) system pressure.
