Raven RCM-Sprayer Hawkeye 2 Calibration And Operation Manual page 24

CHAPTER 3
5. When configuring the system for a pull-type sprayer, measure the distance from the pivot point to the
implement hitch. Enter the measurement in the C field in inches [centimeters].
NOTE: The value entered for the C distance must be measured parallel with the direction of vehicle travel.
6. Press Next to continue with the system calibration.
CALIBRATE INERTIALS
NOTE: If the Hawkeye® 2 system is not installed, the inertials calibration process will not be available. Skip to
the Pressure Sensor Setup to proceed with the calibration wizard.
1. Review the on-screen instructions and confirm the arrow number pointing toward the ground.
2. If necessary, touch the Redetect Orientation button.
3. When the Detected Orientation field matches the RCM - Sprayer ECU orientation, select the Next button to
continue to the Pressure Sensor Setup page.
PRESSURE SENSOR SETUP
1. Use the Boom and Sparge Pressure drop-down fields to select the type of pressure sensor or transducer
connected to the Hawkeye® 2 system.
2. Select the Next button to continue.
PWM SETUP
1. Enter the Coil Frequency of the hydraulic PWM pump control valve.
2. Enter the desired PWM High Limit % for the PWM pump control valve. Enter a value less than 100% to optimize
pump performance.
3. Enter the PWM Low Limit % for the PWM pump control valve. Enter a value above 0% to prevent delayed
pump output when spraying.
4. Check the Standby Pump PWM% and enter a value to maintain pump speed when boom sections are toggled
off.
NOTE: When Sidekick Pro ICD injection pumps are detected, Standby Pump PWM is automatically selected
and is not user-editable. If a check valve is present on the main product line, Standby PWM should be
enabled to prevent delayed pump output when transitioning toggling application on and off (e.g.
turning the boom on and off in headlands or border passes).
5. Select PWM High Side Drive to drive the "+" side of the PWM coil.
NOTE: This is typically only selected for direct drive electric PWM pump applications. Most hydraulic PWM
pump applications will not require PWM High Side Drive to be enabled.
RATE SENSOR SETUP
1. Select the Flow Meter Calibration field and enter the calibration value for the flow meter used to monitor the
product flow.
2. Select the units field and use the drop-down options to select the flow meter units.
NOTE: The flow meter calibration value and units are typically found on a tag or label affixed to the flow
meter. Raven flow meters use a meter cal in pulses per 10 gallons [37.9 L]. Other manufacturers may
use different meter cal units.
3. Enter the Flow Meter Low Limit value. This is the lowest specified reading of the flow meter and can be
obtained from the manufacturer. Raven flow meter low limit values are as follows:
•
RFM 5 - 0.1 gpm (0.4 L/min)
•
RFM 15 - 0.5 gpm (1.9 L/min)
