Calibration Of C500; Adjusting The Box; Determining Your Offset - Pioneer Appli-Pro SLV C500 Operation Manual

Calibration of the C500
Your C500 has been calibrated from the factory at 13.5 volts. Different tractor charging systems, alternators,
voltage regulators, bad batteries, or faulty battery cables may affect the output voltage supplied to the C500,
which could cause variation in initial calibration. We recommend that if any of these components are replaced
during the season, you test and recalibrate your C500. Also test and recalibrate your C500 at the beginning of
each season, and when you have a significant change in tonnage harvested (summer to fall crops). Below are
the steps that walk you through the recalibration sequence.

Adjusting the box

(Must be in SL Mode)
1. Power up the box by pushing the ON/OFF Button.
2. When the display shows the word (STOP), Press and hold the START/STOP button for five or more
seconds. A letter ( C ) should appear on the left side of the screen.
3. Adjust number that is shown on the right side of same screen by pushing the SELECT RATE button.
Note: Some boxes have an offset already programmed into the box from the factory. Make your offset
corrections, from the number that is displayed. The numbers will scroll up only. To get to a number
lower then what is originally displayed you will have to scroll up to 40 and then it will go to a negative
39 and then scroll up. Use the formula listed under (Determining your off set) to get your numbers.
a. Example: The box shows (C – 5) and according to the calculations, you did below, you have
to adjust your box up 18. Since there is a negative number displayed (-5) you will move the
number up 18 from that point. So the new displayed number will be (C 13).
4. When the new number has been achieved, press and hold the Start/Stop button until the
(C) is removed.
5. Power down box by pushing the ON/OFF button. (THIS MUST BE DONE TO SAVE THE NEW
VALUE.)

Determining your offset

1.
Start with a clean and empty tank.
2.
If you are running the C500 in Greenstar mode (GS), switch it to the (SL) mode.
3.
Fill the tank with water to just above the 500 treatable ton mark.
4.
Prime unit.
5.
Set the C500 to run at the rate you are going to be chopping at.
6.
Run the unit at this rate and stop when it gets to the 500 treatable ton mark.
7.
Push the TONS TREATED button and release. Reset this screen by holding the same button for
five seconds. This is your start point.
8.
Press START and run the unit for 100 tons (This is the distance between 500 and 400 on the
bottle).
9.
Once complete, write down the new number from the tons treated screen and use the two simple
equations below (Cross multiplication and subtraction) to determine your offset.
First Equation:
(Tons Treated)
Second Equation: (New Rate) – (Set Rate) = Box Adjustment (amount to change up or down)
(100) (Set Rate)
--------------- = -------------------
X (New unknown rate)
