6.2Proportional Valve Settings
Figure 34: Proportional Valve Settings page
Spraying systems that use a proportional valve are controlling a hydraulic valve, which in turn drives a hydraulic motor which drives a pump. Spray regulation is controlled by changing the pump speed. The settings will need to be tuned for the sprayer.
Select ‘Prop. Valve’ in the ‘Controller’ window.
Select ‘Settings’, this will then open up the window to allow the operator to alter the settings for the proportional valve for the tank selected.
