INTRODUCTION
CHAPTER 1 – INTRODUCTION & INSTALLATION
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 Flex 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.
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 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.

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.

INITIAL STARTUP
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 conguration to verify the rate control system is
operating normally.
4. Using the MANUAL ADJUSTMENT buttons , set
PWM duty cycle to 50%.
5. Use this conguration to verify the rate control system is
operating normally.
• Conrm 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.
• Conrm e-ChemSaver Solenoids is impulsing
• Congure 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 conguration to verify each of the corresponding
e-ChemSaver Solenoids is impulsing.
This conrms the basic functionality of the DynaJet Flex system.
Further details for ne-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 ow greater than
the maximum demand of the system. Consult sprayer
manufacturer specications.
• 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 specic 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 Tests
The following tests will conrm that impulse of ow 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 specied 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 ne 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 ne gain too low will allow the system to continue to
oscillate.
• A ne 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 ne 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 System
The following steps will use the DynaJet Flex’s coarse and ne
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 conguration.
6. Notate Course Gain and Fine Gain values for reference with
Lower Pressure/Larger Droplet Size verication.
7. Run Lower Pressure/Larger Droplet Size verication.
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 ne
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.
Course Gain value at highest pressure/smallest droplet size: ____
Calibrate Fine Gain
4. Using the same speed changes as before, view the Current
Nozzle Pressure diamond on the Nozzle Gauge when
changing speed
5. Begin increasing ne gain until the oscillations stop and the
target rate and target pressure are stable. Most machines
operate with a setting between 8 to 12 for ne gain.
Fine Gain value at highest pressure/smallest droplet size: ____
Lower Pressure/Larger Droplet Size
6. After coarse gain and ne gain have been set, using the
Droplet Size Keys , choose a lower pressure/larger
droplet size that will typically be used by disabling Droplet
Size Keys .
– Example: to
7. Run the system using the same speed changes and view on
the DynaJet Flex the Current Nozzle Pressure diamond on
the Nozzle Gauge when changing speed.
Typically, the settings will not have to be changed for the lower
pressure applications.

Droplet Size Chart
When choosing a spray nozzle that produces droplet sizes in
one of the eight droplet size classication categories, always
remember that a single nozzle can produce different droplet size
classications at different pressures. A nozzle might produce
medium droplets at low pressures, while producing ne droplets as
pressure is increased.

NOTE: Droplet size classifications are based on BCPC
specifications and in accordance with ASABE Standard
S572.1 at the date of printing. Classifications are subject
to change.
