While in the Tips Per Boom Section step, the symbol will be flashing at the
top of the console display. The console will also display “
SEC 1
” at the left and a
number (6) at the right of the display. The “
SEC 1
” refers to boom section #1 on
your sprayer. The number at the right is to be adjusted to match the number of
tips you have on boom section 1.
The default value of “6” will appear for all booms sections. The next 3 or 5
programming steps are Number of Spray Tips Per Boom Section steps. These
steps correspond with the 3 or 5 boom switches on the lower portion of the
console, depending on the 844 console you purchased. The section you are
programming can be identified by looking at the
SEC
# at the left of the display.
You must program the correct number of spray tips for each boom section on
your sprayer. Use the or keys to produce the correct value. Depressing
the and keys simultaneously will clear the value to zero.

User Programmable Tip
Default =
0.00
While in the User Programmable Tip step, the symbol will be flashing above
the
P
tab at the bottom of the display.
In some cases you may find that nozzles other than those pre-programmed
for the 844 Sprayer Control will need to be used. If one of the eleven
pre-programmed tips do not meet your needs, this programming step allows
the user to program a tip.
Use the or key to adjust flow rate in US Gallons Per Minute (Liters Per
Minute) {Imperial Gallons Per Minute} at 40 psi (2 bar). Depressing the and
keys simultaneously will clear the value to zero. To accept the value,
depress the key to advance to the next programming step.
The flow rate information for the tip is only used to calculate the pressure reading
for flow based controls. With non-linear tips, the calculation would be incorrect.
Therefore we recommend a “
0.00
” setting for non linear tips so that the pressure
will read “
0
” at all times, instead of an inaccurate pressure. Non linear tips should
not be used with pressure based controls. Pressure based controls use the tip
flow rate information to adjust the pressure to achieve the right application rate
based on the size of the tips. With non linear tips, there is no way for the
controller to accurately calculate what the pressure should be at various speeds.
