Check LookAhead pressure regulation at section change
1.
Go to menu [4.6 speed simulation]. Key in 4 mph and press # to
use the value.
2.
Press ~ to leave to workscreen.
3.
Press ® button for pressure regulation on the HC 6400. Confirm
that check mark icon appears in upper left corner of the display.
4.
Start PTO at nominal RPM.
5.
Flip down all section switches.
6.
Press main ON/OFF at the grip to ON, to open all sections. Check
that pressure regulation valve rotates and that pressure stabilizes
at 30 psi.
7.
Press main ON/OFF at the grip to OFF, to close all sections.
8.
Flip up half of the section switches to close half of the sections.
Check if pressure regulation valve rotates counterclockwise (to
reduce pressure) immediately after the change of section
switches. If pressure regulation valve rotates when all sections are
closed, then LookAhead is activated and works correctly.
Open/close the Main On/off = No movement
Pressure based regulation (optional equipment)
When the pressure based regulation is enabled, the HC 6500 will
prompt for a nozzle choice. The last used nozzle is designated by the ‰
symbol at the line of the nozzle description in the display. If the nozzle
and application rate used at last spray job is going to be re-used, then
press ~ and the work screen will appear. If another nozzle will be used,
then confirm your nozzle selection by pressing #. Then the minimum
pressure screen will appear. If LookAhead is enabled, then LookAhead
calibration will be done before menu [E8.1.3 Minimum pressure]
appears.
In menu [E8.1.3 Minimum pressure] the minimum pressure allowed is
typed in. Confirm by pressing #.
In practice this means the regulation valve will stop if the pressure goes
below this value. See “Check LookAhead pressure regulation at speed
change” for illustration of pressure regulation valve functionality.
