PROGRAMMING GUIDELINES
IMPORTANT PRELIMINARY INFORMATION
Before you begin, we recommend that you review the following Programming Guidelines that control the pro-
gramming process.
1. For your convenience, the programming of the 844 has been divided into two programming categories;
System Setup Mode and Application Setup Mode.
2. Depressing the key once will flash “P
RO
“ in the upper left hand corner of the display window. The word
“USER” will be displayed in the lower right corner indicating you are about to enter the Application Setup
Mode. Depressing the key a second time will put the Control Console into the Application Setup
Mode. If you inadvertently press the key once, wait for 3 seconds and the Control Console will return
to its normal operating mode.
3. Depressing and holding the and keys while simultaneously pressing the key once will flash
“P
RO
“ in the upper left hand corner of the display window. The word “PrO” will be displayed at the left of
the display window indicating you are about to enter the System Setup Mode. Depressing the key a
second time will put the Control Console into the System Setup Mode. A delay of three seconds will
return the Control Console to its normal operating mode. The System Setup programming steps will likely
only need to be programmed once, to customize the controller to your sprayer.
4. For either setup mode, if you depress and hold the key for 3 seconds, your inputs will be stored and
the computer will exit the respective setup mode. This action will not be necessary until the last program-
ming step has been completed.
5. To increase the value of a programmable digit, depress the key. To decrease the value, depress the
key. These keys are located directly to the right of the display.
6. For some programming steps, depressing and holding the or key will change the program-
mable value rapidly. Pressing the or key once will change the value by one increment.
7. Depressing the and keys simultaneously in some programming steps will set the value to “0”.
8. For either setup mode, depressing the key will advance you to the next programming step.
STEPS TO SUCCESSFUL PROGRAMMING
TO BEGIN THE PROGRAMMING PROCESS:
1. Read above for programming tips.
2. Be sure the “master” boom toggle switch is “OFF.”
3. Turn console “ON” by pressing the key. When the Control console is turned on, the software version
will be displayed at the top of the display and the serial number will be displayed in the lower left of the
display. This information will be needed when calling for service support.
