CHAPTER 1 – INTRODUCTION & INSTALLATION

The DynaJet Flex controller works in conjunction with an existing rate controller that regulates flow via a control valve or pump regulation to achieve a target application rate while maintaining target droplet size(s) when a speed change occurs. This system only works with automatic rate controllers that use flow based monitoring systems and not pressure based monitoring systems. Automatic rate controllers equipped for both flow and pressure based control should have the pressure-based system disabled to work in conjunction with DynaJet Flex.

The independent automatic rate controller loop performs the same as it would if the DynaJet Flex controller were not present. The DynaJet Flex controller changes flow output to each individual nozzle based upon input provided from the operator about the optimum droplet size (pressure) for the application.

SYSTEM COMPONENTS

DynaJet Flex Console The DynaJet Flex console is designed to provide years of service under typical agricultural and turf operating conditions. A tight fitting enclosure means that typical dusty environments will not cause operational problems. While occasional splashing of water will not damage the unit, the DynaJet Flex console is not designed for direct exposure to rain. Take care not to operate the DynaJet Flex console in wet conditions.

INSTALLATION

The following are basic guidelines for installing the DynaJet Flex. Contact the dealer or OEM for additional details.

DynaJet Flex Drivers There will be one DynaJet Flex driver 78-05124 per eight (8) nozzles.

• Mount each DynaJet Flex driver centred within the eight (8) nozzles it controls.

PowerPower will be sourced from the battery using the 60 amp fused cable 45-05943.

Power from the battery will be routed to the boom using the 6 gauge power cables 45-05942-xx

The Power distribution modules 78-05121-xx will connect to the 45-05942-xx cables.

Power will then route from 78-05121-xx to each DynaJet Flex driver 78-05122 using cables 45-05971-xx, and 45-05997-xx or 45-05998-xx.

Nozzle HarnessesWhen installing Nozzle harnesses 45-04005-xx-xx always start with section 1 and continue to the last section.

Nozzle harnesses are designed for your specific nozzle spacing.

Always start with nozzle #1 and work left to right (while facing in the machine’s forward direction.

CAN Cables & TerminatorsThe Start terminator 45-04006-START must be connected to the DynaJet Flex driver 78-05124 for section 1.

CAN cables must be connected in series.

The End terminator 45-04006-END must be connected to the Driver module 78-05124 for the last section.

DynaJet Flex InterfaceThe DynaJet Flex interface 78-05123 connects to the DynaJet Flex interface harness 45-10193:

NO. 2 SETUP UP MACHINE

When initially setting up the system, setting parameters for Units, Number of Sections, Number of Nozzles, and Maximum Pressure Sensor Value is strongly suggested. Selections are automatically saved when adjusted. Other console settings, machine settings and user parameters can be adjusted as needed after calibrating the system.

1. From the Work screen, access the Menu Options .

2. Press the SETUP button .

3. Establish: X Units – Sets the units to US (psi) or Metric (bar). X Number of Sections – Set the number of boom sections.

This should match the number of sections used on the spray controller.

X Number of Nozzles – Set the number of nozzles for each section. This value should match the number of nozzles used on the spray controller. When programming is complete, values should match and show in green.

X Maximum Pressure Sensor Value – Verify this value by looking at the pressure sensor description. Values will be either 10 bar or 25 bar.

NO. 4 GET TO KNOW THE CONTROL MODES

To begin calibrating the system, an operation mode needs to be established. There are two types of Operation Modes:

Nozzle Mode (Pressure) – when the user changes the desired drop sizes choices (via the droplet size selectors checkboxes) the system will recalculate the desired pressure. It will then adjust the PWM duty cycle to attempt to attain the desired pressure in the system.Manual Mode (PWM) – The user can manually adjust the PWM duty cycle to attempt to attain the desired pressure in the system.

NO. 5 PREFORM SYSTEM FUNCTIONAL TEST

The following is instructions for performing a functional test of the system.

• Ensure that current rate control system is operating normally prior to attempting to use the DynaJet Flex.

1. On the Work screen, set DynaJet Flex operating mode to Manual Mode .

2. Using the MANUAL ADJUSTMENT buttons , set PWM duty cycle at 100%. This will make the system operates as if DynaJet Flex was not present.

3. Use this configuration to verify the rate control system is operating normally.

4. Using the MANUAL ADJUSTMENT buttons , set PWM duty cycle to 50%.

5. Use this configuration to verify the rate control system is operating normally.

• Confirm boom section functionality.

1. Continue operating DynaJet Flex in Manual Mode with PWM duty cycle set to 50%.

2. Switch the master switch ON (on rate controller or other boom section control switches)

3. Using the switch box, turn ON each section verifying the proper section turns blue on the DynaJet Flex Work screen.

4. Turn the master switch OFF. On the DynaJet Flex Work screen, verify all sections are now grey.

• Start pump and ensure no leaks.

• Verify pressure on mechanical gauge matches the digital pressure display within reason. If not, adjust maximum pressure sensor value as previously described.

• Confirm e-ChemSaver Solenoids is impulsing

• Configure in PWM mode DynaJet Flex at duty cycle of 50%.

1. On the Work screen, set DynaJet Flex operating mode to Manual Mode .

2. Using the MANUAL ADJUSTMENT buttons , set PWM duty cycle to 50%.

3. Use this configuration to verify each of the corresponding e-ChemSaver Solenoids is impulsing.

This confirms the basic functionality of the DynaJet Flex system. Further details for fine-calibrating the system are in “Calibrate the DynaJet Flex System” section of this guide.

NO. 6 CALIBRATE THE RATE CONTROLLER REGULATION

The following procedure determines the most aggressive rate controller regulation valve gain that will work over all pressure ranges.

Before you begin:• Ensure product pump is providing flow greater than

the maximum demand of the system. Consult sprayer manufacturer specifications.

• Understand that the most aggressive value will be found by increasing valve gain until system oscillates and then decreasing the setting until the system is stable at that value.

NOTE: Other rate controller specific settings may apply based on your specific rate controller system

• The rate controller must be operating in automatic mode during these tests.

• To attain the minimum and maximum operating pressures for the specific nozzle in use under each test condition the user must be able to either: adjust the target application rate, or adjust the machine speed

Flow Impulses TestsThe following tests will confirm that impulse of flow through the solenoids will not affect rate controller stability even when duty cycle is below 50%.

1. Set DynaJet Flex operating mode to Manual Mode .

2. Using the MANUAL ADJUSTMENT buttons , set PWM duty cycle as noted in each test.

3. Preform tests as specified in the following sections, taking note of the pressure levels during each test.

4. Set rate controller valve gain to the highest value that will work with all three of the following tests. This will be the lowest gain value found in the 3 tests. Once established, this value should not need to be changed again.

If the system does not control acceptably with this gain value at all manual duty cycle settings, then something is wrong with the system that needs to be resolved before trying to calibrate the DynaJet Flex System. For assistance, contact TeeJet Technologies Customer Support or an authorised TeeJet Technologies dealer if additional support is required.

NO. 7 CALIBRATE THE DYNAJET FLEX SYSTEM

Coarse gain will be increased until the system is oscillating across the target pressure. Once that is occurring, then fine gain will be increased to smooth/eliminate the oscillation.

• A coarse gain too low will cause the system to be stable but slow to get on target.

• A coarse gain too high will cause the system to overshoot the target range when a speed change happens.

• A fine gain too low will allow the system to continue to oscillate.

• A fine gain too high will cause the system to oscillate too rapidly and cause a thumping in the system.

• The lower the target pressure, the higher the fine gain can be set, so calibrating needs to be done at highest pressure/smallest droplet size that the machine will typically be operating.

• Speed changes will be required for the best calibrating possible.

• Simulated speed changes are preferred, but driving the machine is acceptable.

• Steady speeds are required.

Calibrating the SystemThe following steps will use the DynaJet Flex’s coarse and fine gain settings to calibrate the system:

1. Set DynaJet Flex to Nozzle Mode .

2. Choose the nozzle being used from the Nozzle Selection options or Favourites List .

3. In Setup, set Coarse Gain to 2 and Fine Gain to 2 .

4. In OEM Settings, disable Jump Point by setting value to 0 .

5. Run Highest Pressure/Smallest Droplet Size configuration.

6. Notate Course Gain and Fine Gain values for reference with Lower Pressure/Larger Droplet Size verification.

7. Run Lower Pressure/Larger Droplet Size verification.

8. In OEM Settings, enable Jump Point by setting value to 0.35 bar / 5 psi .

If more than one nozzle size is going to be used on the machine, then run a test with the same values for coarse gain and fine gain for the other nozzles. Always check at the highest pressure/smallest droplet size that will typically be used.

Highest Pressure/Smallest Droplet Size Calibrate Course Gain

1. On the Operation screen, using the Droplet Size Keys , choose the highest pressure/smallest droplet size that will typically be used by disabling Droplet Size Keys .

– Example: to

2. Run the system and view on the DynaJet Flex the Current Nozzle Pressure diamond on the Nozzle Gauge when changing speed.

3. Increase the coarse gain until system is oscillating across the target pressure. Most machines operate with a setting between 4 to 6 for coarse gain.

APPENDIX B – DYNAJET APPLICATION CHARTS

DYNAJET FLEX NOZZLE SELECTION

Selection of the proper spray nozzle for use with the DynaJet Flex system is much like selecting the spray nozzle for a traditional spraying operation. Along with the extra application flexibility, DynaJet Flex brings a few other nozzle-related considerations that will be summarised below.

1. Duty Cyclea. DynaJet Flex controls nozzle flow rate by varying the portion of time that each nozzle is ‘on’ vs. ‘off’. The on time is referred to

as duty cycle. The range of duty cycle available is typically 30% to 100%, meaning that the nozzles on the machine will have the approximately 30% to 100% of their rated flow capacity.

b. With the DynaJet Flex system:• Standard mode spray nozzle flow capacity = spray nozzle size x duty cycle • Dual nozzle mode spray nozzle flow capacity = spray nozzle size x duty cycle x 2

c. By varying the duty cycle, the DynaJet Flex is essentially varying spray nozzle capacity on the fly. When more pressure is required, the nozzle capacity (duty cycle) is reduced. When higher nozzle capacity is required, the duty cycle is increased.

d. Although the operator has a much more flexible and forgiving application system with DynaJet Flex, care should be taken to select spray nozzles that give the best possible results.

e. When selecting a spray nozzle, review the DynaJet Flex nozzle selection charts and select a spray nozzle capacity that produces the target application rate at a duty cycle of about 70% when running at expected travel speeds. In other words, choose nozzle capacity and desired pressure/droplet size closer to the high end of the speed (or rate) range than to the lower end. This will provide plenty of adjustment range for DynaJet Flex to reduce duty cycle when travel speed slows, while also providing additional capacity if travel speed increases above the planned speed.

– The default setting for minimum duty cycle is 30%. This means the system will not adjust the duty cycle below 30% ‘on’. While this setting can be set as low as 20% by the operator, the higher default value provides a more uniform application at lower speeds.

2. Spray Nozzle Selectiona. The DynaJet Flex system is not compatible with all spray nozzles. Approved nozzle series include: AI Turbo TwinJet, Turbo

TeeJet Induction TwinJet, Turbo TeeJet, Turbo TeeJet Induction, Turbo TwinJet, TwinJet 110, TX ConeJet, TXA ConeJet, TXR ConeJet, XR TeeJet 110 and XRC TeeJet 110.

NOTE: Listed series may not include all available capacities. Changes to series and/or capacities may occur with software updates.

b. Different nozzle styles have different droplet size characteristics across the range of operating pressures. The spray nozzle style should be selected based on the desired droplet size at the pressures expected to be in use for your application.

c. Always use spray nozzles with 110° (or wider) spray pattern. These spray nozzle part numbers will typically include the 110 in their name – for example TT11006VP or XR11006-VS. 80° spray nozzles are not recommended with DynaJet Flex.

3. Spray Heighta. In order to achieve the best possible spray coverage, make sure to keep spray height at or above 50 centimeters / 20 inches

from the nozzle to the target.

Nozzle/Tip Selection Chart ExplanationThese coloumns show flow rates at various pressures. The Delta P represents pressure loss through the DynaJet Flex solenoid valve, and the resulting nozzle PSI/bar and flow show actual values at the spray nozzle.

These coloumns show droplet sizes for different styles of spray nozzle at given pressures. Use these coloumns to choose the best nozzle style for your application.

Just like a normal nozzle chart, these coloumns show rates available at given speeds. The only difference is the range of values that corresponds to the range of flows available with DynaJet Flex.

Nozzle/Tip Size Selection ExampleMETRIC: If the operator wants to apply 250 l/ha at 10 km/h, he would look in the 10 km/h coloumn, and find the row that shows 250 l/ha with room above and below to compensate for higher and lower speeds that may be experienced in the field. In this case a TT11006 at 3-4 bar will work very well.

US: If the operator wants to apply 15 GPA at 10 MPH, he would look in the 10 MPH column, and find the row that shows 15 GPA with room above and below to compensate for higher and lower speeds that may be experienced in the field. In this case a TT11006 at 40-50 PSI will work very well.

Nozzle/Tip Series Selection ExampleMETRIC: The next consideration is droplet size. The chart shows that a Turbo TeeJet (TT) nozzle will give Coarse (C) to medium (M) droplets in this pressure range, and a Turbo TwinJet (TTJ60) will give Coarse (C) droplets. The benefit of the TT is that the operator could select droplets from C to M all at the same rate and speed.

DYNAJET® FLEX 7140INSTALLATION/SETUP/USER GUIDE

98-05345-EN A4/LT R2 English-International© TeeJet Technologies 2019

An innovative new product from TeeJet makes spraying more efficient and more productive. The DynaJet Flex system uses a touch screen controller and individual solenoids to control each spray nozzle. This innovative system works along with an existing rate controller, and allows the operator to choose specific droplet sizes that will be used for a particular job. The rate controller manages application rate, and the DynaJet Flex system uses PWM technology to control system pressure and thereby control spray droplet size. Droplet size data is built into the controller so setup is easy and droplet sizes can be changed on the go. PWM control of each nozzle delivers very large ranges of speeds and application rates with a single spray nozzle and with consistent spray quality.
