9 Field-IQ system setup Equipment calibration for Field-IQ
Setting Explanation
Calculate the gear ratio from the encoder to the metering
point of the material.
Calculate the Rawson gear ratio from the motor to the
metering point of the material.
Note –
If the gear ratio is figured incorrectly, the system may
over or under apply, even if it is showing the correct rate on the
screen. You may also have issues in the drive calibration screen.
Calibration Constant A calculated value the system determines during
calibration. To begin, leave the value at 1.000. After the
calibration test, the system may adjust this value.
4.
Place a clean, empty container under the rows that contain seeds to capture the seeds
dispensed during the calibration.
WARNING – Moving parts during this operation. Ensure the implement is safe to operate.
5. Tap Test.
6. The system asks if you would like to prime the system. Tap Yes. To to ensure that the seed disk
is full, the system turns the seed disks one revolution.
7. Turn on the master switch to prime the system and then when prompted on-screen, turn off
the master switch.
8. For Number of Seed Meter Revolutions, enter a value and tap Start. The higher the number of
revolutions the more accurate the calibration. Five to 10 revolutions is recommended.
9. Follow the on-screen prompts of operating the master switch. After the system turns the
specified number of revolutions, enter the number of seeds dispensed per row and then tap
Continue.
10. The next screen shows the minimum and maximum speeds for the target rate specified. Tap OK
and then either press Test to repeat the calibration or tap OK to continue.
11. Select the Limits tab to view a listing of the limits that are set.
12. Tap OK.
13. Repeat the previous steps for other Rawson Control Modules that need calibration.
Hydraulic test
The purpose of this test is to exercise the hydraulics to establish whether there is sufficient oil flow
to run the system. The Rawson hydraulic test is used to make sure the drive will turn. After entering
a desired RPM the master switch is turned on and the drive should begin to turn.
If the drive does not turn, check all electrical connections. If the motor is plugged in properly, it will
make a hissing or whining noise.
