Operations
Before going to the field:
1.
Once calibration procedure above has been
followed, Console will store the calibration
and rate information until new information has
been entered.
Refer to Figure 99
2. Turn on Console by pressing On/VR key.
Pressing the On/VR key twice will put the unit
in VR (Variable Rate) mode. Leave Console in
manual mode.
NOTE: For units with P/N 21567 skip step 3.
3.
To double-check calibration before planting,
follow same procedure as for mechanical
ground drives as outlined in Great Plains Pre-
cision Seeding System Operator’s Manual,
with these differences:
• Volumetric: use extreme caution when per-
forming this calibration to prevent injury due
to drive entanglement. Also, turn drive gauge
wheel with a consistent speed of at least 30
rpm for maximum calibration accuracy.
• Singulated: Rather than calibrating from a
standing start, measure the distance as listed
in the GP manual, and set two flags. Start
driving far enough in advance of the first flag
that your unit is operating at field speed (min.
3 mph) during the calibration distance.
In Field:
Refer to Figure 100
1. Turn on Controller Console by pressing the
On/VR key. Green light above On/VR key will
illuminate when power is on. Pressing the
On/VR key twice will put the unit in VR mode.
VR will appear on the screen along with the
Rate that is being sent from the computer.
Press On/VR key again to toggle back to
manual mode. (Mode and rate changes take
effect with the release of the key.)
2. To change rates manually whether in manual
or in VR mode, simply touch the Up/Down ar-
row keys. This will change the Controller to
the rate you select manually. To return to VR,
simply touch the On/VR key to toggle back to
VR mode.
