CALIBRATIONS-VALVE AND
SPREADER
Valve calibrations are required for proper system operation for
planter, granular, and liquid flow channels. Some calibration
screens vary based on control channel type.
PLANTER CONTROL AND GRANULAR
VALVE CALIBRATION
Performing a valve calibration is required for planter, granular,
fan, shaft, and liquid flow channels to set system parameters and
should be performed for best results. A Valve Calibration button
appears on the control channel screen if this step is appropriate
for the assigned channel type.
TIP: Valve calibration steps 1-10 are the same when performing
for Planter, Granular, Liquid Flow, Fan and Shaft Control.
CAUTION
Hoppers are assumed to be empty for this calibration. If
loaded, material may dispense from the meter.
NOTE
Refer to the System Tests section for using a remote test
switch during a valve calibration.
PERFORM A VALVE CALIBRATION
1. At the Controls screen, press the
VALVE CALIBRATION
button to access the Valve Calibration screen (Figure 64).
-
If necessary, run Limit Output before running the Valve
Calibration. Refer to the Limit Output section.
2.
Move the implement to the “raised” position.
3. Apply the tractor brakes and lock in the applied position.
4.
Put the transmission in “park” or in a locked, neutral position.
-
Verify disc speed high limit is set correctly. Valve
calibration will try and obtain the high disc speed.
DANGER
When the START key is engaged, the machine will
become operational. All necessary precautions must be
taken to ensure user safety. Failure to practice all
necessary caution may result in serious injury or death.
