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/Manual

key in the “MAN” mode, the valve should close when the Plus key is

pressed and open when the Minus key is pressed.
The pressure regulating valve can also be mounted in a throttling

situation as an alternative location. Refer to pages 3 and 4, and Figures

3 and 4.
NOTE: The diagrams in Figures 1 and 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 2 and 3).
