2.  If the system displays within the listed range.
   A. The system is operating correctly.
   If the system displays higher than the listed range, some common problems could be:
   A. Leak in line, tip missing, tip worn, and high tractor voltage.
   If the system displays lower than the listed range, some common problems could be:
   A. Make sure there is preservative in the tank and ball valve is in the open position.
   B. Air in lines. Pump will not prime. Check for leak in lines, or defective check valve.
   C. Pump is working, but not producing desired output. Pump needs to be rebuilt.
   D. Main filter plugged. Check filter by tank and clean if necessary.
   E. Tip or tip screen plugged. Check both tip and tip screen and clean if necessary.
   F. Kink in hose. Straighten or replace hose.
   G. Voltage from tractor is low. Check power cord with multimeter for 12 volts at baler mounted processor. Clean connections on battery. Dielectric grease connections at baler mounted processor and at hitch connection.

4. Drain all lines on the outlet side.
5. Never use oils or alcohol based anti-freeze in the system.
6. For spring start-up, if the pump is frozen, turn off the power immediately to avoid burning the motor out or blowing a fuse. The pump head can be disassembled and freed or rebuilt in most cases. Check the fuses after the pump has been freed.
7. Disconnect power from the Dual Channel Processor.
8. Remove Touch Screen Display from tractor and store in a warm, dry place.

Common Questions

1. How do I turn the system on/off?

– To turn the system ON, simply press anywhere on right side of screen followed by pushing the ‘Press to Start’ key. To turn the system OFF, return to the Main Menu screen and press the POWER OFF key.

2. How to get in the LBS/TON, MC%, and TONS/HR screens?

– In the Main Menu press the SETUP MODE key. From this screen you can change your application rates and how much product is applied. See SETTING UP FOR INITIAL USE for a detailed explanation of this process.

3. The unit is stuck in the Application Rate screen.

– In the Application Rate screen, level 1 must be less than level 2, and level 2 must be less than level 3.
– For example, if level 1 is set at 16, level 2 must be set at 17 or higher, and level 3 must be set higher than level 2.

4. How does OVERRIDE work?

– Override turns on all three pumps at full output.
– The pumps will remain at full output until the operator turns these pumps off by pressing the OVERRIDE key again.

5. The flow meter reading is more or less than the programmed level set in the box.

– Some variation in flow meter readings compared to the programmed set point is normal due to factory tolerances on the pump motors as well as varying tractor voltages inputted to the control box. The flow meter reading is an accurate measure of how much product is actually being applied. The set points then will need to be adjusted if you want to attain a different flow meter reading.

6. Why don’t all the pumps turn on even at higher application rates?

– The selections of what pumps turn on when are automatically controlled by the control box’s flow rate look up chart. Thus, not all the pumps turn on at once and the combination of what pumps turn on when is automatically controlled by the software. If you want to make sure all three pumps are working, go to the – Diagnostics screen and run pump outputs. .

7. The moisture content displays “LO” or “HI” all the time.

– When the moisture content display does not change frequently while baling, there is likely a faulty star wheel connection. One of the first places to check is inside the white star wheel block. Check to see if the electronic swivel is in the star wheel shaft and check to see that the star wheel shaft is not working out of the block. Also, check all star wheel wires and connectors to see if there is a continuity or grounding problem.

8. Should the battery connections be removed before jump starting or charging a battery?

– Yes. Anytime the tractor will have voltage going up rapidly the connections should be removed.

Backup fuse

The Model 462 is equipped with a backup system if your display is not functioning. This function is intended for use only as a temporary means for application and not as a way to apply preservative over multiple fields or for a lengthy amount of time. The baler mounted processor has a location for a backup fuse on the same side as the pump and flow meter harness that bypasses all other system inputs and applies preservative using one pump (Pump Three) at a constant lbs/hour shown below. These values are based upon on input voltage of 13.5 DC. Insert at least a 10 amp up to 20 amp fuse (3 AG style) into the backup fuse port to activate the bypass. The system will not turn off or pause until the fuse is removed. The main fuse must also be functional for the backup fuse to work. | Tip Set| Output (lbs/hour)
---|---|---
462| High| 180
 | Low| 150
