Select ‘Raven’ if the sprayer has a Raven Fast Flow regulator valve fitted.
Note: Unless a KEE part number: 495181 ( KEE Pressure Relief) has been fitted to the Raven
Fast Flow regulator valve. See Section 22 for more information.
The Raven Fast Flow, has a three way valve, which acts as both regulator and dump valve. The
valve will go from fully closed to open in 1.5.seconds. The PWM Setting must left on FULL
(100%) otherwise this will impair the operation of the dump valve and Automatic Section
Control (ASC).
a) Select ‘Raven’
b) Enter the settings for the Raven Fast Flow regulator valve as displayed in Figure 33.
c) Select the option ‘Close Valve When Flow OFF’.
Note: When using a Raven regulator that operates as a ‘Dump Valve’ then select the option
‘Close Valve When Flow OFF’.
Failure to do this could dead end the system and cause damage to pumps, hoses etc.
See Service Bulletin Section 22, if a positive displacement (piston or diaphragm) pump and a
Raven Fast Flow regulator valve is fitted. KEE recommends a Pressure Relief kit (part number
495181) be fitted to the sprayer. If the kit is fitted then follow the settings as recommended
in the Service Bulletin.

All regulator valves have a two wire control system. Polarity is reversed to change the
direction of the regulator when in use.
Select this option if the valve is turning in the wrong direction i.e. pressure is being increased
when the decrease button is selected on the ‘ZYNX Working’ screen.

The ‘Sensitivity’ setting refers to the Flowmeter signal, and may need to be set to ‘Reduced’
to stop ‘hunting’. This setting will also make the response to rate changes sluggish.
It is recommended to select ‘Standard’.
