Configuring the on-board computer
As the SC-Box takes over the spread rate control function, many functions and settings on the onboard computer are redundant.
If you fit an existing system with the SC-Box, you can write down the field sprayer parameters from
the on-board computer and use them as the base for SC-Box configuration.
You can keep these functions as they are, deactivate them and/or set them to 0. Anyway, the SC-Box
will ignore them.
The following table shows an overview of replaced and new functions.

Entering field sprayer parameters
Enter the parameters in the following cases:
▪ Prior to initial start-up.
▪ When the field sprayer parameters change.
The parameters appearing on your screen depend on the type and configuration of your sprayer.
The quantity entered as the target rate will be applied when the sprayer is working in automatic
mode.
Working width of sprayer.
Number of impulses the wheel sensor sends to the job computer on a 100m distance. Used to
calculate the speed.
The number is determined by the wheel sensor calibration.
In Automatic mode, the spray pressure of the nozzles is adapted to the current speed of the sprayer.
The adjustment should ensure that the volume of spray liquid that is applied is exactly what you
defined in the target rate. The regulation factor plays a decisive role here.
The regulation factor adjusts the reaction speed of the regulation:
▪ The higher the regulation factor, the faster the spray pressure is adjusted.
▪ The lower the regulation factor, the more slowly the spray pressure is adjusted.
When setting the regulation factor, you can pay attention to the following:
▪ If, during movement at constant speed, the current application volume jumps around the target
value, you need to reduce the regulation factor.
▪ If, when speed is changing, the application volume does not adjust to the rate quickly enough,
you need to increase the regulation factor.
Set limit values for the spray pressure
This setting defines a spray pressure range within which the spray pressure is optimal.
If the spray pressure is above or below the maximum limit values, an alarm will be triggered.
You can choose your own limit values as required.
If no pressure sensor is installed on your sprayer, you must enter "0" as the value.
SC-Box ignores this parameter.
(Minimum working speed)
If the sprayer speed drops below the minimum working speed, the following happens:
▪ Application will be switched off automatically.
▪ The work screen displays the icon
When the value is set to 0, this function is deactivated.
If the sprayer falls below this speed, the following happens:
▪ The flow will no longer be regulated and the flow remains unchanged.
▪ Manual mode will be activated.

This parameter defines the way the job computer communicates with the terminal and which
information is sent in the process. The configuration depends on the type of terminal.
CAN:
▪ "ME Eco"
For ECO terminals
▪ "ME ISO / no Serial No."
For ISOBUS terminals The serial number of the hardware will not be transferred and will not
appear in the selection menu of the terminal.
▪ "ME ISO / Serial No."
For ISOBUS terminals The serial number of the hardware is transferred via CAN and appears in
the selection menu of the terminal. Important for working with the "ISOBUS-TC" app.

Calibrating the flow meter
▪ At the start of each season.
▪ When you detect deviations between the quantity actually sprayed and the quantity displayed.
▪ When you have replaced or repaired the flow meter.
There are two ways you can calibrate the flow meter:
▪ The tank method – it is time-consuming, but precise.
▪ The nozzle method – it is not as precise as the tank method, but is less time-consuming.
If the calibration is imprecise, the calculations will be very inaccurate and the application imprecise.
Calibrating the flow meter with the tank method
With the tank method, a large quantity of water will be applied from the tank over a specific time.
The flow meter measures the impulses during this time.
After the application, you must enter the quantity of water that has been applied.
The computer calculates the number of impulses per litre.
Spray liquid or spray liquid residues
Danger of poisoning or chemical burning
◦ Clean the spray liquid tank thoroughly prior to calibration. The sprayer must be free of spray
liquids or spray liquid residues.
◦ Use only clear water during calibration.
All sections are selected.
Manual mode is activated (the

Calibrating the flow meter
Calibrating the flow meter with the nozzle method
When calibrating the flow meter using the nozzle method, you determine the average quantity of the
liquid applied through a nozzle in a specific time.
When calibrating using this method, you must apply clean water over the entire working width and
measure the applied quantity on different nozzles using a measuring cup.
The flow meter measures the impulses during this time.
When you have finished the application, you must enter how much water was applied on average by
one nozzle in one minute.
The computer calculates the number of impulses per litre.
Spray liquid or spray liquid residues
Danger of poisoning or chemical burning
◦ Clean the spray liquid tank thoroughly prior to calibration. The sprayer must be free of spray
liquids or spray liquid residues.
◦ Use only clear water during calibration.
You have prepared a measuring cup you can use to measure the applied quantity.
You have prepared a stopwatch to be able to count one minute precisely.
All of the sections are preselected, and the sprayer can apply over the entire working width.

Calibrating the wheel sensor
⇨ The following screen appears:
2. Enter the number of pulses per liter in the line "Pulses main flow".
Calibrating the wheel sensor
▪ When you have fitted a wheel sensor (Sensor X) on the wheel of the tractor.
▪ Prior to initial start-up.
▪ After changing tires.
▪ After tractor change (if the wheel sensor was fitted to the tractor's wheel).
▪ When the speed shown on the work screen is incorrect.
▪ When the traveled distance shown on the work screen is incorrect.
Imprecise calibration
The speed cannot be precisely determined with an incorrectly calibrated wheel sensor.
As a result, all the calculations of the applied area, the traveled distance and the volume applied will
be highly imprecise.
Determining the pulses per 100 meters
When calibrating the wheel sensor with the 100m method, you determine the number of pulses
received by the sensor over a distance of 100 meters.
In order for the system to function correctly, the wheel sensor must receive at least 250 pulses over a
distance of 100 meters.
To increase the number of pulses, you must install additional magnets opposite of the wheel sensor.
If you know the number of pulses for the wheel sensor, you can also enter this number manually.
Wheel sensor is installed.
All wheel sensor magnets are fully functional.
A distance of 100m has been measured and marked. The distance must correspond to the field
conditions. It should therefore lead over a meadow or a field.
The tractor with connected implement is operational for a 100m drive and is positioned at the
start of the marked distance.
1. Ensure that all prerequisites have been fulfilled.
