Menu 3.4.2 Simulated speed value
The “Simulated speed value” menu is used in 2 situations:
Furthermore, when the spraying speed drops below the lowest speed
value, where a spray job can begin when starting at headland (this
speed is set by the HARDI dealer), the speed will be simulated to
maintain normal spray pressure, until the normal spraying speed is
maintained.
÷
NOTE! Default value: 7.2 km/h.
μ
ATTENTION! Use this menu when a spray job has to be finished
before fixing the defect sensors.
μ
ATTENTION! Recommended setting is 75-90% of spraying speed.
•
At standstill or when driving
very slowly, while priming
the boom. This feature allows the sprayer to be stationary or to drive slowly and automatically get
normal spray pressure to prime the boom.
•
If the speed sensor is defect. In this case the computer will assume that the sprayer is travelling at the speed selected
in “Simulated speed value”. The operator should keep the tractor constantly at this
speed to maintain a good regulation with ability to handle changes in application rate
and changes in sections.
The selected speed should be appropriate also for headlands. If the speed is reduced at
headlands, the resulting application rate will be higher than the selected value.
Here is an example:
If the operator selects the application rate to be 100 litres/ha and speed of 8 km/h, and
then reduces speed from 8 to 6 km/h at headlands, the actual application rate will
increase to 133 litres/ha.
