Operations
Before going to the field:
1.
Once calibration procedure above has
been followed, Console will store the cali-
bration and rate information until new infor-
mation has been entered.
Refer to Figure 102
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
Precision Seeding System Operator’s Man-
ual, 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 accu-
racy.
• Singulated: Rather than calibrating from a
standing start, measure the distance as list-
ed 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 103
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 man-
ual or in VR mode, simply touch the Up/
Down arrow keys. This will change the Con-
troller to the rate you select manually. To re-
turn to VR, simply touch the On/VR key to
toggle back to VR mode.
