APPENDIX C
90 Hawkeye Nozzle Control 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 RATE
This value controls the response time of the nozzle control valves. If the response rate is too fast, the valves will
over correct and the system may start to oscillate around the target flow rate. Set a value between 0 to 100, with 0
for fast response rate and 100 for slow.
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
This value controls the response time of the nozzle control valves. If the response rate is too fast, the valves will
over correct and the system may start to oscillate around the target pressure. Set a value between 0 to 100, with 0
for fast response rate and 100 for slow.
REMOTE SENSITIVITY
The sensitivity value sets the sensitivity of the pressure readings into the product controller. The values range from
1 to 9, with 1 the most sensitive and 9 the least sensitive. If the value is set too low, the pressure reading could be
unstable. The default value is 2.
