Troubleshooting GPS-based seed-
ing with PF3000
1. No Target Rate appears on the PF3000
• has field been selected? Select target file (see
PF3000 Settings, Step 4)
• check recipe to verify that it is valid
• if recipe calls for zero rate as the default, do you
have GPS signal, or are you outside of field?
2. No Actual Rate appears on the PF3000.
• actual rate cannot be logged using the PF3000
with the Great Plains Precision Population Con-
troller.
3. Target Rate appears on PF3000 but not on GP
Controller Console.
• make sure GP Controller Console is set to VR
Mode (see Figure 129 page 90)
• double-check all cable connections
• check Nominal rates on both the PF3000 (PF3000
Settings, Step 5), and on the GP Controller Con-
sole (GP Settings, Step 2) These must be set to
the same number.
4. Rates on GP Controller Console and on PF3000
do not match.
• check Nominal rates on both the PF3000 (PF3000
Settings, Step 5), and on the GP Controller Con-
sole (GP Settings, Step 2) These must be set to
the same number.
• Re-check GP calibration number, with metering
wheel and row spacing.
• The recipe rates from the PF3000 are in 4% incre-
ments. If the two rates are within this 4% range,
the units are operating normally.
• Check the target conversion number (PF3000
Settings, Step 6). If the recipe requires a target
conversion number, i.e. the recipe is for 25 which
means 25,000 seeds/acre, the target conversion
number will be 1000. In this case the Nominal
Rate on the PF3000 and on the GP Console
should be near 25,000. See PF 3000 Settings,
Step 5 for calculating Nominal Rate.
5. Population Monitor rate does not match GP Con-
troller Console.
• Make certain that PF3000 and GP Controller Con-
sole agree. If not, see Troubleshooting step 4
above.
• Re-check GP calibration number, with metering
wheel and row spacing.
• Re-check planter monitor settings: calibration
number, row spacing, number of rows, swath
width, seed, etc.
• When planting small size seeds and/or at high
rates, if population monitor consistently indicates
a lower population than the GP Controller Con-
sole, contact monitor manufacturer for perfor-
mance specs for that application.
