TECHNOLOGIES 834-P Sprayer Control Normal Working Mode (GPT Mode) Note: This section covers operation of the 834-P in Gallons Per Ton mode. Operating instructions for Gallons Per Acre mode can be found on page 6. INTRODUCTION In the Gallons Per Ton (GPT) normal working mode, the display can show three different pieces of information indicated by the LED’s below the display e.g.
834-P Sprayer Control TECHNOLOGIES SPEED/RPM DISPLAY (GPT MODE) In this display the shaft RPM is shown on the display. Press the 12 key to advance to the pressure display. tip select GPA GPT Inch lbs/rot Gal/min @40 psi SPEED RPM P/300ft P/rot PSI On min MPH RPM PROGRAM MODE push 3 sec. PRESSURE DISPLAY (GPT MODE) In this display the pressure is shown in PSI. Press the 35 key to advance back to the rate display.
TECHNOLOGIES 834-P Sprayer Control TARGET APPLICATION RATE DISPLAY In this display the application rate in gallons per acre (GPA) is shown. The target application rate will be displayed any time the master boom switch is in the off position (a "t" is on the display when the target application rate is displayed). When the master switch is on, no “t” is on the display and the actual application rate is displayed. Press the + or keys to select another target application rate.
834-P Sprayer Control TECHNOLOGIES SPEED/RPM DISPLAY (GPA MODE) In this display the vehicle speed is shown in MPH. Press the 40.0 key to advance to the pressure display. tip select GPA GPT Inch lbs/rot Gal/min @40 psi SPEED RPM On PSI P/300ft P/rot min MPH RPM PROGRAM MODE push 3 sec. PRESSURE DISPLAY (GPA MODE) In this display the pressure is shown in PSI. Press the 35 key to advance back to the rate display.
TECHNOLOGIES 834-P Sprayer Control Operating Instructions THE SPRAYING OPERATION Fill the sprayer tank and thoroughly mix the chemical(s). Your application rate should be determined as well as the spray tip you will be using, with the sprayer data programmed into the computer. Switch the computer on by pressing the key on the display panel.
34-P Sprayer Control TECHNOLOGIES Alarms and Warnings On the 834-P Console there are three LED's for indication of alarms or warnings. • The Speed alarm LED flashes when no speed pulses are received during spraying (Master in the ON position). This indicates that there is something wrong with the speed sensor or that you are standing still while spraying.
TECHNOLOGIES 834-P Sprayer Control Programming Guidelines Make sure that all hardware components are properly installed and tested. Before you start the programming process you should first check if the console and all sensors are working properly.
834-P Sprayer Control TECHNOLOGIES Console Programming (GPT Mode) To begin the programming process: Be sure the Master boom switch is “OFF.” Turn console “ON” by pressing the key. When the control console is turned on, the software version will be displayed for approximately 5 seconds. At the same time all LED’s will be ON. The software version and serial number of the console will be needed when calling for support. The serial number is located on a sticker on the back of the console. Y1.
TECHNOLOGIES 834-P Sprayer Control System Setup Mode (GPT mode) The System Setup Mode contains the programming steps that customize the controller to the sprayer or sprayer components. These include calibration steps and parameters that, once programmed, are not likely to change. To enter the System Setup Mode: First be sure that the console is ON (if not turn it on by pressing the until the normal display is visible). key and wait Ensure the Master boom switch is OFF.
834-P Sprayer Control TECHNOLOGIES SHAFT SENSOR CALIBRATION The shaft speed sensor needs to be calibrated in order to provide the proper speed reading. The value for this step is the number of pulses generated by the shaft speed sensor in one revolution. For example, if the shaft speed sensor is mounted to sense the teeth of a sprocket, enter the number of teeth on that sprocket. SPRAY TIP CAPACITY Enter the combined capacity of all nozzles on the system.

TECHNOLOGIES 834-P Sprayer Control SPEED SENSOR CALIBRATION Default = 250 pulses/300ft The speed sensor needs to be calibrated in order to provide the proper speed reading. The value for this step is the number of pulses generated by the speed sensor in 300 feet. For example, if the speed sensor is mounted to sense lug bolts on a sprayer wheel, this value would reflect the number of bolts passing the sensor over a 300 foot distance.
834-P Sprayer Control TECHNOLOGIES Radar A radar speed sensor will be indicated with an "r" on the display e.g. The "r" will automatically appear during the auto calibration process when the console has determined that a radar is being used. When manually entering a radar calibration number the "r" must be turned on by pushing the Auto/Man key. With this key you can toggle between radar or wheel sensor. The calibration value itself is adjusted with the + and r10.
TECHNOLOGIES 834-P Sprayer Control SPRAY TIP CAPACITY Enter the combined capacity of all nozzles on the system. This should be measured in Gallons Per Minute at 40 PSI. These capacities can be obtained from the nozzle manufacturer’s catalog. Use the + or keys to adjust this value. Once the correct units have been selected, press the key to advance to the next step. Example: Two 8004 nozzles would have a combined capacity of .8 GPM at 40 PSI.
