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.
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. 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.
Work screen
On screen indicators
Current droplet size – displays the current droplet size using both the
appropriate colour droplet icon and size letter code.
PWM duty cycle – displays the current PWM duty cycle as a
percentage.
Active solenoid (high flow mode only) – displays if one or both sets of
solenoid are active.
Actual pressure – displays the actual pressure.
Current nozzle selection – displays the current selected nozzle.
Boom status
►Blue – turned on (standard mode or high flow mode single
solenoid active)
►Green – turned on (high flow mode both solenoids active)
►Empty – turned off
Pressure gauge
►Red diamond – actual pressure
►Colors – droplet size,
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.
Droplet size selectors
►Red X and greyed out – not selected
High flow mode
►Single – one set of solenoids active
►Dual – both sets of solenoids active
Droplet size chart
When choosing a spray nozzle that produces droplet sizes in one
of the eight droplet size classification categories, it is important to
remember that a single nozzle can produce different droplet size
classifications at different pressures. A nozzle might produce medium
droplets at low pressures, while producing fine droplets as pressure
is increased.
