HAWKEYE® NOZZLE CONTROL AND SIDEKICK PRO ICD SETUP
overridden and the rate controller will maintain maximum pressure. For the Hawkeye
®
nozzle control, the
maximum operating pressure of Hawkeye
®
nozzles is 80 PSI (550 KPA).
NOTE: The maximum pressure feature may result in lower than desired application rates. If the maximum
pressure feature will be used during field operations, be sure to enter a value that will not interfere
with normal target rates during field application.
SPARGE PRESSURE CALIBRATION
This option will only appear if a transducer is detected. Sparge Pressure Calibration calibrates the sparge pressure
transducer (if present) to a known value. The system will calibrate this automatically during the calibration wizard
but the value can be adjusted at any time. Calibrate to a known pressure using a pressure gauge or turn the
product pump off and open the section valves to relieve sparge pressure before resetting to zero.
Sparge Pressure Calibration is presented on the control valve selection on PWM and a second pressure transducer
is detected on the sparge or system agitation line. This value can typically be controlled by an operator in the cab.
For Fast or Standard valve operation, this value changes to Pump Pressure and represents the pressure at the
pump. The system will control the Pump Pressure value if the master switch or all boom switches are Off.
BOOM PRESSURE CALIBRATION
This option will only appear if a transducer is detected. A boom pressure transducer is required for Hawkeye
®
system operation. Calibrates the boom pressure transducer (if present) to a known value. The system will calibrate
this automatically during the calibration wizard but the value can be adjusted at any time. Calibrate to a known
pressure using a pressure gauge or turn the product pump off and open the section valves to relieve boom
pressure before resetting to zero.
PRESSURE TRANSDUCER CALIBRATION
To calibrate the Hawkeye
®
system pressure transducers:
1. Open the UT Menu and select the Hawkeye
®
Menu button.
2. Select the Tools Menu softkey along the right side of the display.
3. Select the System Settings tab along the top of the display.
4. Select the Pressure Settings button.
5. Verify the Pressure Type and Transducer Type selections.
6. Zero the transducer at ambient air pressure. Refer to the Advanced Transducer documentation provided with
the equipment, or contact the equipment manufacturer, for assistance with bleeding pressure from the
application system.
NOTE: If the Hawkeye
®
system came installed on the equipment from the equipment manufacturer, or if a
sparge pressure transducer is installed with the Hawkeye
®
control system, check the transducer
specifications and refer to the Advanced Transducer Calibration to verify transducer settings before
operating the Hawkeye
®
nozzle control system during field applications.
ADVANCED TRANSDUCER CALIBRATION
Navigate to the second page of the Pressure Settings menu to access the following settings:
Pressure Type. Select the pressure type drop down field and select the boom or sparge transducer to be
calibrated for Hawkeye
®
operation.
Transducer Type. Select the transducer type drop down field and select the range for the transducer used with
the Hawkeye
®
system. The following options are available for calibrating the Hawkeye
®
nozzle control system:
