Duty Cycle Percentage
Setting Duty Cycle Percentage – Using PWM
The 1550+ spray controller can be used for PWM, Pulse Width Modulation. This feature is only used with electrically
actuated spray nozzles, like the PulsaJet
®
spray nozzle from Spraying Systems Co.

This unique feature allows the system to control the flowrate by ‘pulsing’ or rapidly opening and closing the spray
nozzle during the
spray period .

This works in the application by the system receiving the sensor or trigger signal the system is activated; the start
delay time is activated.

Once the delay time is finished the spray period starts the system then sprays for the set amount of time.

During the spray period the controller sends a duty cycle signal to the nozzle at a rate based on the percentage.

The percentage of the time in which the nozzle is spraying is controlled by this setting. The duty cycle percentage
can be set from 1 to 100 percent.

The driver frequency is calculated by the controller based on the duty cycle % inputted on the home screen and
the maximum frequency inputted on the setup screen.
