X20 Sprayer Reference Manual

Reverse Valve Direction

All Regulator Valves have a two wire control system. Polarity is reversed to change the direction of the regulator when in use.

Select Reverse Valve Direction if the valve is turning in the wrong direction, ie: pressure is being increased when the decrease button is selected on the Working screen.

Close Valve When Flow Off

Select this option if using a 3 way Regulator Valve, which also operates as a Dump Valve, such as the Raven Fast Valve.

Also select this option if Anhydrous Gas is being used through the regulator.

Sensitivity

The Sensitivity setting refers to the Flow Meter signal and may need to be set to Reduced to stop ‘hunting’. This setting will also make the response to rate changes sluggish.

TIP TIP

It is recommended that Standard is selected.
