Page 5: Chapter 1 - Introduction
844-AB cHApter 1 – introduction This User Guide provides information for software version 4.02. Make sure that all hardware components are properly installed and tested. Before starting the programming process, confirm that the console and all sensors are working properly. IMPORTANT! Before beginning, review the following program Guidelines that control the programming process. -
Page 6: Chapter 2 - Application Mode
844-AB cHApter 2 – ApplicAtion mode cHApter 3 – oem setup The 844-AB gives the possibility of working in two different ways OEM Setup mode contains the options that customize the controller to fit the application. Therefore, the console should be set up and to the sprayer or sprayer components. -

844-AB minimum Voltage display stable This will determine the minimum voltage that can be applied to the This will determine allowed tolerance percentage on the displayed dose regulation valve. If too low, the valve won’t fine tune the dose rate. If rate. -
Page 8: Memory Option
844-AB cHApter 4 – system setup memory option This feature enables the user counters. System Setup mode contains the options that customize the controller to the sprayer or sprayer components. These include calibration steps Select NO to disable this feature or YES to enable it. and parameters that will rarely change once programmed. -
Page 9: Units Of Measurement
844-AB units of measurement sensor selection The 844-AB is capable of working in either US or SI (Standard The 844-AB can accommodate a flow meter, pressure transducer or International metric). Use the Plus and Minus keys to switch both. Sensor Selection instructs the console which sensor is being units. -

844-AB Engage the sprayer pump. Turn the boom sections “On” and begin Flow meter pulses spraying a known volume of fluid (e.g. 100 gallons/400 liters). As the During the Flow Meter Pulses step, the symbol (flow meter turbine) known amount is sprayed, the console will count the pulses. After the will flash at the top of the console. -

844-AB pressure transducer low pressure pressure transducer maximum rating (p Hi) calibration (p ref) The Pressure Transducer Maximum Rating establishes the maximum rating of the pressure transducer. This number can be found stamped The Pressure Transducer Low Pressure Calibration step is used to on the pressure transducer. -

Page 13: Simulated Ground Speed
844-AB simulated ground speed reference Flow rate per section Simulated ground speed allows the console and sprayer to be tested AB Mode – The flow rate for each section of the sprayer must be input (and actually spray water) without physically moving the sprayer. This into the 844-AB console so that the necessary adjustments can be can and should be tested prior to any spraying activity. -

Once established, this value should not sprayer will regulate. When the vehicle slows down, the control system change unless the regulating valve is physically moved to a new will sometimes regulate the pressure so low that it falls below the plumbing location. -

Page 17: Chapter 5 - Swath Width Presets
844-AB cHApter 5 – swAtH widtH presets selecting swath preset The 844-AB can be programmed with up to 6 swath widths. This allows the operator to easily change from one swath to another during Once the swath widths are programmed, select the swath width to be application. -

844-AB cHApter 7 – operAtions Before operating, check connections related to the Sprayer Control NOTE: It is recommended that the entire sprayer be calibrated in Assembly. The sensors should be checked to ensure the console preparation for operation and to diagnose wear to spray receives uninterrupted signals. -

844-AB cHApter 8 – FeAtures Boost mode Area/Volume display Increased or decreased chemical application may be required during The 844-AB records application area and measures the total volume certain areas of application. The Plus and Minus keys allow for applied while the Master Boom Switch is in the “ON” position. The easy adjustment. -
Page 22: No Flow Alarm
844-AB no Flow Alarm If the 844-AB stops receiving pulses from the flow meter, the turbine symbol will flash at the top of the display. This indicates that there is a problem with the flow meter or elsewhere in the system. This alarm will occur only when the Master Boom Switch and at least one boom toggle switch are set to the “ON”... - Page 24 8 4 4 a b s p r ay e r c o n t r o l U s e r g U i d e M a n U a l 1801 Business Park Drive Springfield, Illinois 62703 USA www.teejet.com 98-70007-ENUS R4 English-US ©...
