DynaJet Flex
DYNAJET FLEX OVERVIEW
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 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 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.
INSTALLATION
CONSOLE
The DynaJet Flex console is designed to provide years of service under typical agricultural 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
Dynajet Drivers
Nozzle Harnesses
The DynaJet Drivers will mount on the boom at the end of each
section.
Each section will require Nozzle Harnesses designed for your
specific nozzle spacing and number of nozzles.
There will be one DynaJet Driver 78-05122 per boom section with a
limit of 20 nozzles per section.
• Mount them so they are at the end of each section that is
closest to the middle of the boom.
Power
Power will be sourced from the battery using the 60amp 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.
When installing Nozzle Harnesses 45-05935-xx-xx always start with
Section 1 and continue to the last section.
• Nozzle harnesses are built with an even number of outputs.
• Some sections will use more than one harness to equal the
number of nozzles in that section.
The yellow and white solenoid cables on the nozzle harnesses must
alternate across the entire boom. When sections have odd numbers
of nozzles then accounting for the altering can be accomplished
one of two ways:
a.By crossing the two solenoid cables
b.By installing Nozzle Harness Reversing Adapters 45-05952
Power will then route from 78-05121-xx to each DynaJet Driver
78-05122 using cables 45-05971-xx.

Ready to Pressure Test the System
1. Ensure that current rate control system is operating at the
optimum level. Set DynaJet operating mode to manual and set
PWM duty cycle at 100%. This will make the system operate as if
DynaJet was not present. Use this configuration to verify the rate
control system is operating normally.
2. Keep DynaJet operating mode on manual and change PWM
duty cycle to 50%. Use this configuration to verify the rate control
system is operating normally.
3. Confirm boom section functionality by observing the row of
rectangles below the on the operating display.
5. Start pump and ensure no leaks.
6. Verify pressure on mechanical gauge matches the digital
pressure display within reason. If not, adjust max. pressure
sensor value as previously described.
7. Configure in PWM mode DynaJet at duty cycle of 50%. Confirm
each e-ChemSaver (ECS) is pulsating.
At this point the system is functioning. Further details for fine-tuning
the system are available in the User Settings section of this guide.
4. Switch the master switch ON (on rate control or other boom
section control switches) and individual sections one at a time.
Make sure each section appropriately changes colour to blue.
With the master switch OFF, all active sections will be grey again.

Units
Minimum Duty Cycle
Sets the brightness level of the display. Range is 5% to 100% in 5%
increments.
Sets the units to US (psi) or Metric (bar).
Sets the value from the pressure sensor description. Either 10 bar or
25 bar.
Sets the minimum duty cycle to which the DynaJet will control.
Default is 30%, minimum is 20%.
Higher values reduce the overall control range of the system.
Key Beep
Enable/disable all beeping from console.
Control Hold Delay
When any boom switch changes state, DynaJet Flex will not make
control adjustments for the specified time period. Range is 0.0 to
10.0 seconds. Default is 1.0 second.
Number of Sections
Set the number of boom sections. Range is 1 to 15.
Fine Gain
Boom Section On/Off Beep
Enable/disable beep when a boom section is turned on or off.
Allows the control system to make minor adjustments when close to
the target, with the goal of stable pressures and minimal overshoot of
target. Range is 0 to 100. Default is 30.
Fine gain settings are 1/10 as powerful gain as coarse gain settings.
98-05334-EN R1
9
DynaJet Flex
Coarse Gain
This is the more aggressive gain setting and will have the largest
impact on the stability and function of the DynaJet Flex system.
Coarse gain makes major adjustments to duty cycle to attempt to
bring actual pressure back to the target. A Coarse Gain setting that is
too high will result in pressure oscillation. Range is 1 to 100. Default
is 5.
Coarse Gain On
This setting determines the threshold at which Coarse Gain becomes
active. Value is shown in the pressure units previously chosen (bar or
PSI). Range is 0.07 to 1.38 bar.
For example, if operating in PSI units with a setting of 7; coarse gain
becomes active when actual pressure is 7 or more PSI away from
the target value. Increasing this value makes the Coarse setting in
effect less of the time (higher value means higher tolerance between
actual pressure and target pressure). Decreasing this value means
coarse regulation is active more frequently. Setting coarse gain ON
too high would disable the feature. Decreasing this value too much
will result in pressure oscillations.
Coarse Gain Off
This setting determines the threshold at which coarse regulation
is switched OFF and fine regulation takes over. Value is shown
in the pressure units previously chosen (bar or PSI). Range
is 0.07 to 1.38 bar (1 to 20 psi).
This value must be lower than coarse gain ON. For example, if
operating in PSI units and with a setting of 4; coarse regulation
will be switched OFF (and Fine Gain becomes active) when the
difference between target and actual pressure is 4 psi or less.
Regulation will remain in Fine until the error reaches the Coarse Gain
On value described above.

TUNING DYNAJET
1. Identify the speed range, rate range and system pressures for the application. Ensure the operating conditions are compatible with the
nozzle capacity, speeds and duty cycles shown in the TeeJet PWM nozzle selection guide.
2. Using the identified speed range based on nozzle selection use the rate controllers test speed or simulated speed to target a desired
application rate and droplet size.
3. Fine tune the regulation performance of the rate control system and the DynaJet system.
a.Typical settings used for DynaJet fine-tuning include Fine Gain, Coarse Gain, Coarse Gain On and Coarse Gain Off.
b.Coarse Gain On must be a higher value than coarse gain Off. A good starting point for Coarse Gain On is a pressure value that is
about 35-40% of the target pressure.
c. Coarse Gain Off value is typically is about 25% of the target pressure, or 5-10 PSI (0.3 - 0.6 bar) lower than Coarse Gain On.
d.Coarse Gain On and Coarse Gain % are used to make major adjustments to pressure regulation. Once coarse gain has brought
pressure near target; Coarse Gain Off and Fine Gain will influence the smaller adjustments.
e.Coarse Gain should be increased if large pressure adjustments need to be made more quickly.
f. Fine Gain should be decreased if actual pressure constantly moves across the target pressure.
DynaJet and the existing rate controller are two control systems that must coexist. Because DynaJet is a second control device that is
installed on the same liquid system, users should be prepared to adjust the rate controller regulation settings to harmonize the two system.
For example, if subtle changes in duty cycle on DynaJet induce noticeable rate or pressure oscillations, the rate control regulation gain
settings may need to be reduced. Placing the rate control system in manual regulation mode during the tuning process will help determine if
oscillations are being caused by the DynaJet or by the rate controller.
TeeJet control systems like 844E, 854 or Radion will typically perform better with DynaJet when their coarse and fine regulating speeds are
reduced by 2-3 digits.
General rule of thumb under normal operating conditions for flow rate changes; DynaJet in combination with the rate controller should have
rate/pressure stabilized in ~ 2-3 seconds.
98-05334-EN R1

DynaJet Flex
DYNAJET NOZZLE SELECTION
Selection of the proper spray nozzle for use with the DynaJet system is much like selecting the spray nozzle for a traditional spraying operation.
Along with the extra application flexibility, DynaJet brings a few other nozzle-related considerations that will be summarized below.
1. Duty cycle
a. 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 system:
Spray Nozzle Flow Capacity = Spray Nozzle Size x Duty Cycle
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, care should be taken to select spray
nozzles that give the best possible results.
e.When selecting a spray nozzle, review the DynaJet 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 to reduce duty cycle when travel speed slows, while also providing additional capacity if travel speed
increases above the planned speed.
i.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 Selection
a. The DynaJet system is not compatible with air inducted spray nozzles. Be sure to select a conventional spray nozzle for use with the
system. The recommended options are XR TeeJet, DG TeeJet, Turbo TwinJet and Turbo TeeJet.
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.
3. Spray Height
a. In order to achieve the best possible spray coverage, make sure to keep spray height at or above 20″ from the nozzle to the target.
12

DynaJet Flex
Nozzle Selection Example
These columns show flow rates at various
pressures. The Delta P represents pressure
loss through the DynaJet solenoid valve, and
the resulting Nozzle PSI and Flow show actual
values at the spray nozzle.
These columns show droplet
sizes for different styles
of spray nozzle at given
pressures. Use these columns
to choose the best nozzle
style for your application.
Just like a normal nozzle chart, these columns 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.
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.
The next consideration is droplet size. The chart shows that a Turbo TeeJet (TT) nozzle will give Very Coarse (VC) 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 VC to M all at the same rate and speed.

INSTALLATION, SETUP AND USER GUIDE
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 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.
