844E Sprayer Control
NOTE: If you are going to be spraying with a different density of liquid other than water and you have
programmed that specific gravity (density) into the Specific Gravity (Density) Step in the System Setup
Mode, you must select the
D
symbol at the top of the display in order for all of the calculations to be
performed in the regular spraying mode. If when in the regular spraying mode, you do not see the
D
symbol at the top of the display, this means that you have not selected a different specific gravity of liquid
and that all calculations will be performed with water (1.00).To spray with a different density liquid, the
specific gravity must first be programmed into the System Setup Mode in the Specific Gravity (density)
step on page 24. Once a number has been programmed into that step, you must select the
D
symbol in
the Application Setup Mode by pressing the Auto/Man key.
NOTE: The tip flow rate, in the lower right corner of the display, will always display the flow rate in US Gallons Per
Minute (Liters Per Minute) {Imperial Gallons Per Minute} at 40 psi (2 bar), regardless of changes to the
indicated pressure.
After performing the calculations, you can advance to the beginning of the Application Setup sequence to make
any changes by pressing the
key once. If no changes are necessary, you have completed the Application
Setup Mode of the TeeJet 844 Sprayer Control.
NOW, PRESS AND HOLD THE
KEY FOR THREE SECONDS, AND THE ENTIRE APPLICATION SETUP
MODE WILL BE STORED IN THE COMPUTER’S MEMORY.
NOTE: For your protection, the 844 console will not automatically power down while in the Application Setup
Mode. You must exit properly as described above to enable the console auto power down feature.
NOTE: Cutting the power to the controller while in the Application Setup Mode will not save any changes made
into the computer’s memory.
