Troubleshooting GPS with PF3000
1. No Target Rate appears on the PF3000
• Has field been selected? Select target file (see
PF3000 Settings, step 5, page 57)
• 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 Con-
troller Console.
• Make sure GP Controller Console is set to VR
Mode (see Figure 37 on page 38).
• Double-check all cable connections
• Check Nominal rates on both the PF3000
(PF3000 Settings, step 6, page 57), and on the
GP Controller Console (GP Settings, step 4,
page 58) 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 6, page 57), and on the
GP Controller Console (GP Settings, step 4,
page 58) 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 Set-
tings, Step 6). If the recipe requires a target con-
version 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 6, page 57 for calculating Nominal Rate.
5. Population Monitor rate does not match GP Control-
ler 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.
