The PLC (Programmable Logic Controller) is
mounted on the joystick console. It is activated
when the PTO switch is turned ON.
The Main screen displays debris tank and clean
water levels, vacuum pressure and the rotation
speed for each spray bar. Buttons at the bottom of
the display are used to set the maximum RPM for
each spray bar (0-3000 RPM), raise and lower the
rotation speed of each spray bar and turn spray
bar rotation ON or OFF. The operator can also se-
lect different screens to change the PLC operation
mode or program different preset maximum head
speed RPM settings into the memory.
