DynaJet®Flex
DYNAJET® FLEX OVERVIEW
The DynaJet Flex controller works in conjunction with an existing rate controller that regulates ow 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 ow based monitoring systems and not pressure based monitoring systems. Automatic rate controllers equipped for
both ow 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 ow 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 and turf operating conditions. A tight tting
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.

DynaJet® drivers
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 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 driver
78-05122 using cables 45-05971-xx.
Figure 2: Installation diagram - standard mode
Nozzle harnesses
When installing nozzle harnesses 45-05935-xx-xx always start with
section 1 and continue to the last section.
Each section will require nozzle harnesses designed for your specic
nozzle spacing and number of nozzles.
• 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

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 conguration 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 conguration to verify the rate control
system is operating normally.
3. Conrm boom section functionality by observing the row of
rectangles below the on the operating display.
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.
5. Start pump and ensure no leaks.
6. Verify pressure on mechanical gauge matches the digital
pressure display within reason. If not, adjust maximum pressure
sensor value as previously described.
7. Congure in PWM mode DynaJet at duty cycle of 50%. Conrm
each e-ChemSaver (ECS) is pulsating.
At this point the system is functioning. Further details for ne-tuning
the system are available in the user settings section of this guide.

remember that a single nozzle can produce different droplet size
classications at different pressures. A nozzle might produce medium
droplets at low pressures, while producing ne droplets as pressure
is increased.

the system.
Setup is used to congure units, display brightness, key beep,
number of sections, boom section on/off beep, maximum pressure
sensor value, minimum duty cycle, control hold delay, ne gain,
coarse gain, and coarse gain on/off.

increments.
Units
Sets the units to us (PSI) or metric (bar).
Key beep
Enable/disable all beeping from console.

Set the number of nozzle locations for each boom section.
Range is 1 to 120.
Section number
Number of nozzle locations
Boom section on/off beep
Enable/disable beep when a boom section is turned on or off.
Maximum pressure sensor
Sets the value from the pressure sensor description. Either 10 bar or
25 bar.
Minimum duty cycle
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.
Control hold delay
When any boom switch changes state, DynaJet Flex will not make
control adjustments for the specied time period. Range is 0.0 to
10.0 seconds. Default is 1.0 second.
Fine gain
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.
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.
Range is 0.07 To 1.38 bar.
For example, if operating in bar units with a setting of 0.48; coarse
gain becomes active when actual pressure is 0.48 or more bar
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.

13 www.teejet.com
DynaJet®Flex
Coarse gain off
This setting determines the threshold at which coarse regulation is
switched off and ne regulation takes over. Value is shown in the
pressure units previously chosen. Range is 0.07 to 1.38 bar.
This value must be lower than coarse gain on. For example, if
operating in bar units and with a setting of 0.28; coarse regulation will
be switched off (and ne gain becomes active) when the difference
between target and actual pressure is 0.28 bar or less. Regulation
will remain in ne until the error reaches the coarse gain on value
described above.
OEM settings
The settings described below are engineering and development
values used in development of the DynaJet Flex system. Do not
alter these settings unless directed by TeeJet Technologies support
personnel.

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 identied 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 ne-tuning include ne 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 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 ne gain will
inuence 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 ne regulating speeds are
reduced by 2-3 units.
General rule of thumb under normal operating conditions for ow rate
changes; DynaJet in combination with the rate controller should have

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 exibility, DynaJet brings a few other nozzle-related considerations that will be summarized below.
1. Duty cycle
a. DynaJet Flex controls nozzle ow 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 approximately 30% to
100% of their rated ow capacity.
b. With the DynaJet system:
• Standard mode Spray Nozzle Flow Capacity = Spray Nozzle Size x Duty Cycle
• High ow 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 y. 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 exible 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.
• 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.

Nozzle selection example
These columns show ow rates at various
pressures. The Delta P represents pressure loss
through the DynaJet solenoid valve, and the
resulting Nozzle bar 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 ows available with
DynaJet Flex.

If the operator wants to apply 120 l/ha at 10 km/h, he would look in the 10 km/h column, and nd the row that shows 120 l/ha with room above and below to compensate for
higher and lower speeds that may be experienced in the eld. In this case a TT11006 at 3-4 bar 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 benet of the TT is that the operator could select droplets from VC to M all at the same rate and speed.
