Menu 3.7.X LookAhead calibration
At start-up of the HC 6500, the user is prompted for a nozzle choice. If
the selected nozzle holds no LookAhead calibration in the HC 6500
memory, it will need to be calibrated.
Press ® to enable “auto” mode prior to calibration. Calibration method:
1.
Select menu 3.7 and press #.
2.
Select the nozzle to be calibrated and press #.
3.
Enter an application rate in the display.
4.
Confirm by pressing #.
Two spraying speeds for calibration are now calculated in the HC
6500. Set P.T.O. revolutions to fit the calculated spraying speed.
5.
Start spraying at the calculated speed.
6.
While spraying at calculated speed, a digit in the 3rd line of the display “Counter to 9” is counting up to 9. If calibration
value is found, “ok” is shown in the display. If a value is not found, the digit starts re-counting up to 9 until a value is
found.
7.
Another calculated speed is now shown in the display. Repeat steps 5 and 6 again for this 2nd calculated speed. It is
preferred to maintain the same P.T.O. revolutions at second driving speed.
8.
The digit in the display counts up as told in step 6. But when a value is found this time, “done” is shown in the display
since calibration is now finished.
If custom nozzle LookAhead calibration is selected, the flow at 40 psi must first be defined.
1.
Enter value.
2.
Confirm by pressing #.
3.
Do all the above calibration routine as usual.
μ
ATTENTION! To calibrate, the speed must exceed the minimum speed set in the controller memory. If minimum
driving speed is set too high, please contact your local
HARDI®
dealer.
μ
ATTENTION! If all section valves are turned off, then LookAhead is in standby. When turning single sections off, e.g.
in wedge shaped fields, then the last valve must be turned off by using the main on/off.
μ ATTENTION! During the entire calibration process, the fluid system should be in “Auto” mode. If not, press ® to
enable it.
μ ATTENTION! When using very large nozzles, it could be necessary to reduce speed until application rate is stable.
μ
ATTENTION! If controller suggests a speed lower than min. regulation speed, then choose a higher application rate.
