Problem 11
Second line does not work correctly
Information
Dual line Sprayers give a larger effective speed range of
operation without the need to change nozzles to travel faster or
slower and maintain the desired application rate. The X20 uses
2 different methods of controlling a second line, which is deter-
mined by the hardware tted to the Sprayer. The rst method
is to control the individual valves on both lines. For this the
X20 is congured as a dual line. The second line is turned on
as required by setting the low speed shutoffs for the second line
valves. The second line follows directly on from the main line
valves, ie: a 6 section Sprayer has boom 1 second line valve
on section 7. A fully featured harness is required to control this
conguration.
The second system uses a single output to control the second line.
For this, the Sprayer needs to be congured as a single line, with one
more section enabled than is used for spraying. This extra section
uses the speed to turn the line on at the right time, and must be
congured with a zero width. The hardware needs to be setup to
control the second line, either with a valve to turn the liquid on, or an
interface to drive the second line valves.
The X20 does NOT have Tiered Switching but with the Dual line
type of conguration, by setting the cut in speeds, you can determine
which line come on rst.
