X20 Sprayer Reference Manual
100kpa.
The idea is to maintain a spray pattern, even if the application
rate is above the desired rate. If a value is set in this option, and
the Sprayer speed falls below the set value, the spray system
switches to Manual mode and locks the Regulator Valve. When
the Sprayer is in this mode it is most likely that the Sprayer will
be over applying the chemical.
When the Sprayer speed goes above the set value the spray
switches to Auto mode and the Regulator Valve will start
controlling.
Select the calculator icon in the Low Pressure Hold window
(Figure 8-16 on page 8-46) to enter the value (in kph). Select
Enter to save the value you entered and close the window.
Pressure Boost
Leave the Pressure Boost value at ‘0’ when using a 6 second
Regulator Valve or faster and especially when using ASC.
Pressure Boost is a function mainly used for viticulture
applications and if using a 20 second Regulator Valve (slow).
The idea is to close the regulator to increase the pressure in
the Sprayer after the boom spray has switched OFF under
Low Speed Shutoff, so the correct application occurs when the
Sprayer turns ON again, when entering the next row.
The Pressure Boost compensates for the pressure loss the Sprayer
experiences as it travels slower, coming out of the row or when
entering the row.
Select the calculator icon in the Pressure Boost window (Figure
8-16 on page 8-46) and enter the value (normally 2-3 seconds).
