TeeJet 844 Sprayer Control - Manual (Page 29)

APPLICATION SETUP MODE
The Application Setup Mode contains the programming steps that are most
frequently changed (target application rate, and nozzles used). Spraying Systems
Co. has added this separate setup mode to speed the programming process
when minor changes are made in the spraying operation (i.e. changing fields,
switching nozzles, changing crops, etc.). The operator can avoid toggling through
all of the programming steps unnecessarily.
To enter the Application Setup Mode, depress the key twice. Depressing the
key once inadvertently will cause the display to flash “
” in the upper left and
“ USEr ” at the lower right of the display for three seconds before the 844 will return
to normal operating mode. The “ ”/ “ USEr ” indicates that the console is about to
enter the Application Setup Mode. Depressing the key a second time puts
the Control Console into the Application Setup Mode.
Target Application Rate
US Default = 20.0 US GPA
Trf Default = 2.00 Gal/1000 ft 2
iNp Default = 20.0 Imperial GPA
nh3 Default = 200 Pounds of Nitrogen/Acre
si Default = 200 l/ha
While in the Target Application Rate step, the application rate, pressure, speed,
and flow rate in US GPM (l/min) {Imperial GPM}, will be displayed. The
application rate units (GPA, G/1000 ft
2 or l/ha) will be flashing indicating that the
corresponding value can be adjusted or programmed.
Your target application rate should be entered in this step. Depress the or
keys to adjust the value. Depressing the and keys simultaneously will
clear the value to zero. When the desired application rate has been entered,
depress the key to accept the value and advance to the next step.
NOTE: If you are using NH
3
units, only the Target Application Rate will
appear in this step.
Nozzle Selection
Default = Red or 0.4 US GPM (1.29 l/min) {0.33 Imperial GPM}
While in the nozzle selection step, the display will remain the same as in the
Target Application Rate step except the symbol 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 20.
