844E Sprayer Crontrol
98-70006 R3
Pressure Regulator in Throttling Mode
The pressure regulating valve, as shown in the
fi
gures below, can be located in the supply line before the boom
control valves. If you choose this location, the 844 will need to be properly programmed to reverse the polarity of
the valve. This step can be found in the System Setup instructions on page 23. When in throttling mode, the valve
should open when the
key is pressed, and close when the
key is pressed. Be sure to check this before
plumbing the valve into the system.
