HARDI LookAhead
With LookAhead, the pressure regulation valve can predict the correct setting before the main switch goes to ON. It
improves application precision, also when re-starting after a tank fill.
LookAhead helps farmers who have tractors with semiautomatic gearbox, meaning the “hardimatic” function does not work
due to constant PTO revs.
The LookAhead system has 3 main features:
1.
To improve regulation response time when sections are shut OFF or opened.
2.
To improve regulation response time when the spraying speed changes during headland turns.
3.
To stabilise regulation during pressure/flow fluctuations in the period immediately after main ON/OFF function is
turned ON.
The LookAhead feature is active when the boom is unfolded and the LookAhead menu is activated and calibrated.
When the power is switched to ON, note the regulation valve will adjust from the actual setting to the minimum setting and
then back again to determine its actual position.
For LookAhead to function correctly the controller must know which nozzles and application rate will be used. This is
selected from a number of nozzle choices stored in memory. At start up of the controller, it will promt user for a choice
between using nozzles used at last spray job or select a new nozzle to be used.
μ
ATTENTION! The tractor gearbox must be an automatic or semi-automatic type with constant revolutions P.T.O. or the
tractor must be driven with constant R.P.M. for the LookAhead to work properly.
