1
To configure the items on this menu, you must enable the speed limit.
Set the minimum spraying speed: the VT closes the main valve when the tractor speed is lower than the set value.
2
To configure the items on this menu, you must enable the pressure limit.
Set the minimum spraying pressure: the VT blocks the automatic regulation of the proportional valve when the pressure is lower than the set value.

When using a paddle flowmeter and the sprayed fluid has a different viscosity than that of water, the VT could display wrong measurements;
to correct them change the flowrate correction factor:
• if at the end of the spraying the tank still contains fluid, reduce the factor;
• if the fluid finishes before the job has ended, increase the factor.
Flowmeters of the ORION series (code 462xxx) are not affected by the viscosity difference of the fluids: set the value to 1.00.
4
If the sprayed fluid is lighter than water, the device may indicate wrong measurements; to correct this measurement, edit the sprayed liquid weight,
referred to 1 liter of product.
A tank level sensor must be installed.

Regulating valve positioning
to enable this function, to be used with a control unit without
calibrated backflows and with
the active automatic management of spraying points (Seletron systems)
.
OPERATION
When spraying is interrupted during treatment by setting main control to OFF (i.e. at the end of the field), the control valve fully opens to reduce system
pressure to the minimum level.
When spraying is restored (main control set to ON), the control valve partially closes to restore output to the correct pressure level.
Use this function to set the
Flowrate limit
(with main control set to OFF), under which the control valve closes for the duration of the set
Activation time
, so as to increase the pressure level before main control is set to ON and to restore the correct treatment in the shortest delay.
