Pressure Regulator in Throttling Mode
The pressure regulating valve, as shown in the 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 14. When in throttling mode, the valve should open when the Plus key is pressed, and close when the Minus key is pressed. Be
sure to check this before plumbing the valve into the system.
