While in the nozzle selection step, the display will remain the same as in the Target Application Rate step except the indicator arrow
will be
flashing at the bottom of the display just above a color coded strip.
NOTE: The tabbed color strip along the bottom of the display represents color coding for TeeJet® VisiFlo® spray tips. If you are using tips made
by another manufacturer, you should use the programmable tip capacity as explained in the System Setup section on page 14.
Select the representative color to match the spray tips being used to apply the desired application rate. Use the Plus key or Minus key
to toggle the indicator arrow through the tabbed color strip at the bottom of the display panel. The corresponding flow rate for each color will
be displayed in US Gallons Per Minute (Liters Per Minute) {Imperial Gallons Per Minute} at 40 psi (2 bar) at the lower right of the display. If the
programmable tip is to be used, toggle the indicator arrow symbol to the “P” tab. Flow rate will always be displayed in US Gallons Per Minute
(Liters Per Minute) {Imperial Gallons Per Minute} at 40 psi (2 bar) regardless of any changes to other display parameters.
The table at the bottom indicates flow rates in US Gallons Per Minute (Liters per Minute) {Imperial Gallons Per Minute} at 40 psi (2 bar) for the
TeeJet® VisiFlo® color coded spray tips represented in the 844 Spray Control.
WARNINg: Color coding of spray tips is not uniform from manufacturer to manufacturer. Flow rates for all nozzles should be checked prior to use.
Tips that are worn should be replaced to ensure an accurate application rate.
Required Speed to Achieve the Application Rate
Based on the tip programmed and nozzle spacing (programmed in the System Setup Mode), the 844 console will calculate the required
speed to achieve the application rate that was entered in the last programming step. The speed will be displayed in the lower left corner of the
display window. Keep in mind that this speed is based on a spraying pressure of 40 psi (2 bar). More calculations can be performed in the next
programming step.
When the correct flow rate for the spray tips being used has been entered, press the Program key to accept the value and advance to the next
step.
