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, conrm that the console and

all sensors are working properly.

IMPORTANT! Before beginning, review the following program Guidelines that control the programming process.

To exit any Setup Mode, press and hold the Program key for 3 seconds. The inputs are stored and the computer will exit Program Mode.

To increase the value of a programmable digit, press the Plus key. To decrease the value, press the Minus key. These keys are located

directly to the right of the display. For some program steps, press and hold the Plus and Minus keys to quickly change the values. Press the

Plus and Minus keys once to increment/decrement the values by one unit.

Press and hold the Plus and Minus keys simultaneously to reset the value to “0” or begin automatic calibration.

Press the Program key to advance the system to the next program step. After the nal program step is complete, the console will nish the

programming loop and return to the initial programming step.

System Setup mode contains the options that customize the controller to the sprayer or sprayer components. These include calibration steps and

parameters that seldom change once programmed.

Application Setup mode contains settings that are frequently changed (tip spacing, number of tips per boom section, density, nozzles used and

target application rate).

CHAPTER 2  APPLICATION MODE

The 844-AB gives the possibility of working in two different ways

to t the application. Therefore, the console should be set up and

consequent programming and working features will be dependant of

the chosen mode.

Airblast Mode

This mode is designed to work with Airblast sprayers, mostly spraying

on two sides (Left and Right) with the possibility to switch on or off

sections in the height. The working width is dened by the distance

between two rows of trees. This mode is called AB (airblast).

Figure 4: Airblast (AB) Principle

Vineyard Mode

This mode is designed to work with vineyard sprayers that are spraying

horizontally. Several rows are covered and sections can be switched

on or off to adapt the working width. Each section covers a number of

faces. The working width is dened by the number of faces and the row

width.

One or more nozzles can be spraying each face. If all nozzles spraying

on a face are not equal, they should be considered as a unique nozzle

and the total ow has to be set up in the conguration menu. But all

faces have to be sprayed equally. This mode is called HC (vineyard).

Figure 5: Vineyard (HC) Principle

CHAPTER 3  OEM SETUP

OEM Setup mode contains the options that customize the controller

to the sprayer or sprayer components. These include calibration steps

and parameters that will never change once programmed.

ADVISORY! OEM setup parameters (except HC/AB mode) should

not be changed unless advised by TeeJet Technologies or an

authorized dealer.

To enter System Setup mode, power off the console. Press and hold

the Plus and Minus keys simultaneously. While holding the

Plus and Minus keys, also press the Program key four times

(within 3 seconds) and then release all keys to enter OEM Setup mode.

Press and hold the Program key for three seconds to exit OEM Setup

mode. Changes will be saved to the console’s memory.

Application Type

As explained above, the 844-AB is capable of working in either Airblast

(AB) or Vineyard (HC) mode.

Use the Plus and Minus keys to switch from AB to HC mode.

Press the Program key to accept the value and advance to the next

program step.

Sensor Selection

The 844-AB can accommodate a ow meter, pressure transducer or

both. Sensor Selection instructs the console which sensor is being

used on the sprayer. The default value is “FLO” (ow-based system)

using a ow meter. To maintain this setting, press the Program

key to advance to Flow Meter Pulses. To change the setting to “PRS”

(pressure based system), use the Plus or Minus keys to select

“PRS”. Press the Program key to advance to Flow Meter Pulses.

NOTE: Pressure-based regulation is used only with linear tips. For

non-linear tips, ALWAYS select flow-based regulation. Most tips

are linear and may be used with pressure-based regulation.

ConeJet tips are non-linear.

If both sensors have been installed on the sprayer, this step will

determine which sensor will be used.

◄If “FLO” is selected, the ow meter will be used to control ow

and the pressure transducer will be used only to display actual

pressure.

◄If “PRS” is selected, the pressure transducer will be used to

control ow and display the actual pressure. Flow meter signals

will be ignored.

The regulation mode determines the following program steps.

◄If “FLO” is selected, the next Setup Mode screen displayed will

be the calibration step for the ow sensor (refer to Flow Meter

Pulses).

◄If “PRS” is selected, the next Setup Mode screen displayed will

be the calibration step for the pressure transducer (ow sensor

calibration will be skipped).

Flow Meter Pulses

During the Flow Meter Pulses step, the symbol (ow meter turbine)

will ash at the top of the console. The ow meter calibration number

can be entered manually from the factory-calibrated ow meter pulse

rate tag or an Auto Calibration procedure can be activated to determine

ow meter pulses based on a known volume of uid.

Manual Entry

Locate the factory-calibrated ow meter pulse rate tag on the ow

meter. If this varies from the default value (it usually does) of the

console, use the Plus or Minus keys to modify the value.

In some cases, larger ow meters with small calibration numbers

will include decimals for greater accuracy. To add a decimal to the

calibration number, press the Auto/Man key.

Automatic Calibration

To complete an automatic calibration of the ow meter, press the

Plus and Minus keys simultaneously. This will clear the existing

value and initiate the calibration procedure. “CAL” will be displayed

in the screen. This indicates that the controller is ready to begin the

calibration process.
