Using Automatic mode
 
In automatic mode, the job computer regulates the degree of opening of the control valve and the main valve on the manifold such that the target rate defined for the application rate can be reached.
 
 
You are in automatic mode when one of the following icons appears in the spray data area of the work screen:
 
 
Icon on the work screen
Meaning
Sprayer can apply.
The speed of the sprayer is lower than “Regulation off below”
Sprayer can apply. The flow will not be regulated. The control valve remains in the last known position until the speed changes.
The speed of the sprayer is lower than “Sprayer off below”
The main valve is closed automatically.
Regulation is not possible because the application was deactivated by the SECTION-Control app.
 
 
 
Requirements
 
 
 
To use automatic mode, the following conditions must be fulfilled:
▪
Target rate has been entered.
▪
Flow meter is calibrated.
▪
A speed signal is available.
▪
Working width is set.
 
▪
The speed of the field sprayer is higher than the speed for the “Regulation off below” parameter.
 
▪
The parameter “Regul. factor” has been set.
 
 
 
Mode of operation
 
 
 
In the following cases, the flow is automatically adjusted:
▪
Speed of the sprayer has changed.
▪
Number of switched-on sections has changed.
▪
You have changed the target rate manually.
▪
The application rate has been changed by the information from the application map.
 
 
The speed and precision of the regulation depends on the value of the “Regul. factor” parameter.
You can change the target rate manually while driving in Automatic mode.
 
 
To operate this function the user needs the ME joystick first of all.

Procedure
 
 
 
To change the target rate during work:
1.
 FS_JR3_Regelung AUTO MANU - Activate automatic steering.
2.
 FS_JR3_Regelung EIN AUS - Open main valve.
⇨
Spray cones appear under the boom icon on the work screen. Still, the sprayer is not spraying.
⇨
As long as you are at a standstill, the sprayer cannot start spraying. See icons:  SY_JR3_Regelung aus and  SY_JR3_Kein Durchfluss
3.
Exceed the speed defined in the “Regulation off below” parameter.
⇨
The sprayer begins adjusting the application rate to the defined target rate.
4.
 FS_JR3_Regelung-Sollwert +10 or  FS_JR3_Regelung Sollwert -10 - Press to change the target rate.
⇨
The degree of change appears on the work screen.
5.
 FS_JR3_Regelung Sollwert 100 - Restores the original target rate.
6.
If you have entered several target rates in the configuration, you can also use the function icons:  FS_Sollwert 1 wählen and  FS_Sollwert 2 wählen to switch among the target rates.
