Operations
Before going to the field
Once calibration procedure above has been followed,
Console will store the calibration and rate information
until new information has been entered.
Refer to Figure 97
1.
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 2.
2. To double-check calibration before planting, follow
same procedure as for mechanical ground drives as
outlined in Great Plains Precision Seeding System
Operator’s Manual, with these differences:
Volumetric: use extreme caution when performing
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 98
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 arrow 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.
3. Engage the hydraulic flow by pushing FORWARD on
the tractor remote hydraulic lever. The remote lever
must be LOCKED OPEN in this position to provide
constant flow to the drive motor.
