844E Sprayer Crontrol

MOUNTING SPRAYER COMPONENTS
Pressure Regulator in Bypass Mode
All pressure regulating valves for the 844 will be wired for use in a
by-pass system. While plumbed in a by-pass mode, with the Auto/
Man key in the “MAN” mode, the valve should close when the
key is pressed and open when the
key is pressed.
The pressure regulating valve can also be mounted in a throttling
situation as an alternative location. Refer to page 5, and Figures
1-3 and 1-4.
NOTE: The diagrams in Figures 1-1 and 1-2
are shown as general
guidelines to follow when plumbing the 844 components.
The type of pump used and location of other components
can vary from sprayer to sprayer. It is important to ensure
that if a pressure transducer is used, it is located as close
to the spray tips as possible. Normally, this is at the boom
control valves. However, if one particular boom section is
always used, the pressure transducer can be mounted on
that particular boom section. If a flow meter is used, make
sure that all of the flow going through the flow meter is
directed to the spray tips. Make sure that proper distance
is allowed on the inlet and outlet side of the flow meter
(refer to figures 1-2 and 1-3).
