APPENDIX C
92 ISO Product Controller II and Hawkeye Operation Manual
FOR EXAMPLE:
Application Pressure = 30 PSI, Target Application Rate = 20 GPA, Target Speed = 5.2 MPH, and Nozzle Spacing
= 20 inches
Using the calculated nozzle volume per minute of 0.35 at an application pressure of 30, select a boom nozzle
which comes closest to providing the desired output.
PRODUCT CALIBRATION SETTINGS
RESPONSE SENSITIVITY
The response sensitivity controls how sensitive the system is to changes in pressure, flow, and speed. Decrease if
the system pressure and rate oscillate slightly. Increase sensitivity if control is unresponsive. Avoid setting response
rate and sensitivity above 70. The default value is 50.
DEADBAND
The deadband value is the allowable difference between the target rate and the actual application rate. The values
range from 1 to 9, where 1 equals a 1% difference and 9 equals 9% difference.
PRESSURE CONTROL SETTINGS
RESPONSE RATE
The response rate controls how fast the system adjusts pressure and rate output. Decrease response rate if system
pressure and rate oscillate greatly. Increase if control is unresponsive. Avoid setting the response rate and
sensitivity above 70. The default value is 35.
