Auto-calibration with external control of the application rate
In some cases, it is advisable to switch the automatic calibration off
temporarily. For example, if you are spreading by means of an
external signal. It can also happen that the dosing unit is closed at any
time while the spreader is connected. If the spreader automatically
recalibrates at that time, it might determine a partially incorrect
discharge curve. If the external system drives the dosing units open
shortly thereafter, the application rate will deviate from the desired
value because in the discharge curve, the flowrate calculated for the
highly deviant dosing setting is not totally correct.
See also section »The ISO control system« on page 30.
You can prevent similar errors by entering a flowrate limit in the
'Settings 3' screen. Below this flowrate, the control system will perform
automatic calibration but will continue to use the last set discharge
curve.
Setting calibration limit on or off
Press the option field calibration limit on/off.
The tick indicates that the automatic calibration is switched off
below the set limit.
Setting calibration limit
If you switch the limit on, you can then enter in the input field the flow
rate value under which automatic calibration is switched off.
Press on the input field of the flowrate.
The popup keyboard displays the old value.
Enter the desired flowrate.
The new value is on the screen of the keyboard.
Press the OK key to confirm the value
or cancel with the cancel key.
Automatic calibration stops below the new flowrate of 15 kg/min.
