Function Diagram for Regulation Valve
μ
ATTENTION! Auto-mode icons are shown, but they could be
Manual or Increment Steps icons, depending on driver selection.
Spray job begins
Start condition:
Controller is turned OFF. Pump is turned OFF.
Pressure SmartValve to pressure draining/TurboFiller. Suction
SmartValve to main tank. Water in main tank.
Driver action
Turn the controller ON.
Controller reaction
Controller detects no pressure or flow.
Starts in auto-mode. Sets regulation valve to safe angle to
avoid overpressure at pump start, and to ensure that software
detects, that pump is started (avoiding delay).
Driver action
Turn the pump ON.
Controller action
Controller detects no pressure or flow. Stay in safe position.
Driver action
Turn Pressure SmartValve to Spraying.
Controller reaction
Headland (boom is closed)
Software uses nozzle size and feeds forward
to prepare for opening of boom.
Max. pressure limit is disabled, because last
saved nozzle size is reliable, and therefore the
software “dares” to close the regulation valve
completely.
Headland (boom is closed)
for over 5 minutes
Boom has been closed for a
longer period, so that operator
could have changed to
another nozzle size. Last saved
nozzle size becomes
unreliable.
Software enables maximum
pressure limit.
Controller reaction
Headland (boom is closed)
Controller detects pressure at armature and bypass flow back
to tank. Software uses last saved nozzle size and feeds forward
to prepare for opening of the boom.
Max. pressure limit is enabled, because last saved nozzle size
is unreliable, and therefore the software will not close the
regulation valve completely. PrimeFlow booms are primed.
Driver action
Turn Main valve OFF at headland.
Turn Main valve ON to spray.
Driver action
Turn Main valve OFF at headland.
Turn Main valve ON to spray.
Controller reaction
Spraying (boom is open)
Boom is open and sprays.
Both flow measurement and pressure
measurement are good, and the actual
nozzle size is calculated.
The actual nozzle size is used to adjust to
correct volume (liter/hectare).
Flow and pressure are
good
Both flow measurement and
pressure measurement are
good.
Software disables maximum
pressure limit.
Controller reaction
Spraying (boom is open)
Boom is open and sprays.
Software uses last saved nozzle size and pressure sensor to
adjust to correct volume (liter/hectare).
Max. pressure limit is enabled to avoid overpressure. in case
operator has changed to smaller nozzles.
