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.
Start 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 service support. The serial number is located on a sticker on the back of the console. U2.
System Setup Mode The System Setup Mode contains the programming steps that customize the monitor to the sprayer or sprayer components. These include calibration steps and parameters that, once programmed, will likely never 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). ☛ Ensure the Master boom switch is OFF. ☛ Then press and hold the key and wait key for 3 seconds to enter the Program Mode.
press the key to advance to the next step. SPEED SENSOR CALIBRATION 250 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. Tip select GPA tip spacing (inch) MPH PSI speed cal (pulses/300ft.) density On PROGRAM MODE push 3 sec. Auto Calibration The speed sensor can be automatically calibrated by driving 300ft.
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 r10.0 Tip select tip spacing (inch) GPA MPH PSI speed cal (pulses/300ft.
TIP SPACING 20 Default = 20 inches keys to adjust this value. Use the + or Once the correct units have been selected, press the key to advance to the next step. Tip select GPA tip spacing (inch) The value shown is represented in inches. MPH PSI speed cal (pulses/300ft.) density On PROGRAM MODE push 3 sec. PRESSURE REGULATING MODE Default = byP The default value "byP" indicates that the pressure regulating valve is plumbed in a bypass line. If the default value is correct, press the key.
Normal Working Mode INTRODUCTION In normal working mode, the display can show four different pieces of information indicated by the LED’s below the display e.g.
SPEED DISPLAY In this display the speed is shown in MPH. Press the key to advance to the pressure display. 3.5 Tip select GPA tip spacing (inch) MPH PSI speed cal (pulses/300ft.) density On PROGRAM MODE push 3 sec. PRESSURE DISPLAY In this display the pressure is shown in PSI. Press the display. 42 key to advance to the tip selection Tip select tip spacing (inch) GPA MPH PSI speed cal (pulses/300ft.) density On PROGRAM MODE push 3 sec.
TIP SELECTION DISPLAY This display is the tip selection display. On the display the two last digits of the VisiFlo color coded tip are shown, e.g. an XR11004 corresponds with _04. (See Table Below) The last selection _P is a programmable selection in case the tips being used do not match one of the preprogrammed flow rates. _04 Tip select tip spacing (inch) See the following page for programming instructions on the _P selection. GPA MPH PSI speed cal (pulses/300ft.
Programmable Tip As mentioned above the _P section of the Tip Selection Display can be programmed to match the flow rate of the tips on the sprayer if they do not fall into one of the categories listed above. To access the programmable section, while viewing the _P display, simulataneously press the Auto/Man and keys for 3 seconds. The display will then display a flashing flow rate represented in US GPM at 40 PSI. The Tip Select LED will also be flashing.
Operating Instructions SPRAYER CHECKOUT Before spraying check all connections related to the Sprayer Control assembly. Particular attention should be given to the speed sensor to be sure the sensor and bolts or magnets are inline, and properly secured or that the radar is installed at the proper height and correct angle. Very important: Whenever you are working around a sprayer or farm chemicals, be sure to wear protective clothing and eyewear.
THE SPRAYING OPERATION You have filled the sprayer tank and have thoroughly mixed the chemical(s). Your application rate has been 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. ☛ Toggle the boom switches to their “ON” position, for each of the booms on your sprayer.
Alarms and Warnings On the 834 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.
