Menu 3.4 Regulation user setup
The sensitivity of the pressure regulation valve can be adjusted.
The values is to be set for obtaining precise regulation, even if a
sensor fail.
The valve is controlled by up to five main sensors:
• Sprayer speed sensor:
This sensor reads the sprayers forward speed which is used
for calculating the volume rate at all spraying speeds.
• Flow sensor:
This sensor reads the flow at the operating unit which is used
for calculating the pressure at all flow rates.
• Pressure sensor:
This sensor reads the pressure at the operating unit which is
used for calculating the flow at the pressure regulation valve.
• PTO RPM sensor:
This sensor read the pump RPM’s which is used to calculate the flow from the pump at all pump speeds.
• Regulation valve opening angle sensor:
This sensor read the opening angle for the rotary valve inside. When the opening angle is known, the flow can be
calculated when the pressure is also known.
The result is when forward speed, pump RPM’s, etc. is known, then the regulation valve can predict a setting (Feed
Forward) before opening the main ON/OFF. Thereby the volume rate is correct even the forward speed has changed
significantly since closing the main ON/OFF (no fluctuation).
Menu 3.4.1 Flow sensor restriction
The menu defines the resistance in the plumbing and circuits of
the specific sprayer setup.
As the resistance varies with the choice of flow house, this must be
set up prior to spraying.
The flow sensor restriction value is fixed for the flow sensor
currently used with the SmartCom system. The value must be set
for the specific sprayer:
Sprayer Value (L/min)
NAVIGATOR without options 156
NAVIGATOR with DilutionKit 127
NAVIGATOR i 112
MEGA 1” hose* 100
MEGA 5/4” hose* 176
MEGA 1” hose* and with DilutionKit 88
MEGA before February 2019 63
