7. Press FIELD key. Set Field. Set Product (press key to right of product).
Settings for Great Plains Precision Population Controllers:
1. Connect PF3000 to console using 9-pin serial cable.
2. Follow instructions to set calibration number based on row spacing and metering wheel.
3. Press Function key and go to Rawson mode. Press Function key until the nominal rate appears on
the display. Using the Up/Down arrow keys, set the nominal rate to the same number as you set the
PF3000 in step 5 above. Once nominal rate is set, press Function key until the main operating
screen appears.
4. Press On/VR key again to toggle to VR mode. VR should appear on the screen along with the rate
that is being sent from the PF3000. Verify that the rate shown on the GP Controller Console is the
same as the recipe sent from the PF3000. Press Engage key to activate the Precision Population
Controller.
5. To change rates manually when 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.
Troubleshooting GPS-Based Seeding with PF3000
1. No Rx rate appears on SiteMate
• 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 Controller
3. Target Rate appears on PF3000 but not on GP Controller Console
• make sure GP Console is set to VR mode
• double-check all cable connections
• check Nominal Rates on both the PF3000 (PF3000 Settings, step 5) and on the GP Console (GP
Settings, step 2); these must be set to the same number
4. Rates on GP Console and on PF3000 do not match
• check Nominal Rates on both the PF3000 (PF3000 Settings, step 4) and on the GP Console (Gp
Settings, step 2); these must be set to the same number
• recheck GP calibration number with metering wheel and row spacing.
• the recipe rates for PF3000 are in 4% increments; If the two rates are within this 4% range, the units
are operating normally
• check the target conversion number (PF3000 Settings, step 2); 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 num-
ber will be 1000; (In this case the Nominal Rate on the PF3000 and the GP console should be near
25,000); see PF3000 Settings, step 4 for calculating Nominal Rate
5. Population Monitor rate does not match GP Controller Console
• make certain that PF3000 and GP controller Console agree; if not, see Troubleshooting, step 4
above.
• recheck GP calibration number with metering wheel and row spacing
