FIGURE 4. Symbols
9. HP+ uses P1 & P2 pressures to monitor pump performance. A 'Pump Fault' message is displayed if the pump
does not boost pressure after 10 seconds of operation and shuts the pump off after 60 seconds.
ADJUSTING THE RATE CAL
Enter the target rate in actual pounds [kilograms] of nitrogen (N) per acre [hectare].
CALCULATING THE REQUIRED CAPACITY
To ensure that the desired application rate (in pounds [kilograms] of actual nitrogen per minute) does not exceed
the AccuFlow system capacity, the required capacity of the application must be verified.
Using the following formula to calculate the required capacity:
Target Application Rate x Target Application Speed x Implement Width = lbs[kg](N)/min
5940[60,000] (EQ 1)
NOTE: Be sure to enter the target application rate in pounds [kilograms] of nitrogen per acre [hectare] and
the implement width as calculated in the “Entering Boom Cal” section on page 43.
If boost pump speed or 'Max Pw' is set too high, excess vapor will form in the supply lines. If vapor builds up in the
supply lines, the boost pump may become vapor locked which results in no pressure boost.
This is more likely to occur when plumbing is too small, nurse tanks are near empty, in cold conditions, or plugged
strainers. Reduce travel speed or lower pump speed (Max Pw) setting as required to reduce boost pump RPM.
FOR EXAMPLE:
(English Units) Given a target application rate of 150 lbs(N)/acre at an average of 5.5 mph and a calculated
implement width of 480 inches, the required capacity is:
