Select the representative color to match the spray tips being used to apply the

desired application rate. Use the or keys to toggle the symbol 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 symbol to the “

” 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

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.

Feature:

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,

depress the key to accept the value and advance to the next step.

Calculation/What If? Step

This Programming Step is a diagnostic tool only and has no effect on the

operation of the TeeJet 844 Sprayer Control. It allows the user to adjust the

indicated pressure to see what effects it would have on the operating speed;

or the user can adjust the speed to see what pressure would need to be used

to maintain the target application rate. This step should help determine if the

correct nozzle size was chosen for the application.

While in the calculation step, either the pressure “PSI” (bar) or speed “MPH”

(Km/H) units will be flashing.

Adjust Speed:

While in the Calculation Step, the user is able to view the nozzle flow rate,

pressure, speed and application rate simultaneously. When first entering this

step, the speed “MPH” (Km/H) units will be flashing, indicating that this digit can

be changed. By depressing the or keys, the programmer can change

the indicated speed to a desirable speed or typical operating speed.
