Configuration Test

PC22402-UN-01APR16

A - Start Button

B - Flow and Variance Table

Perform a Configuration Test to ensure that the system is functioning properly.

Always fill solution tank with clean water to perform configuration test.

Turn master switch off or leave Diagnostics at any time to cancel test.

1. Turn master switch on.

2. Select Start button (A).

When test starts, the following procedures are automatically performed:

1. Test Started

2. Agitator Test

   If equipped, agitator valve opens for 15 seconds.

3. Section Valve Test

   Each boom section valve is individually cycled on and off for approximately 6 seconds, starting from left to right then back from right to left. All boom section valves are then turned on for approximately 10 seconds.

4. Flow Control Test

   Flow control valve is tested across entire range of flow. Results are displayed in Flow and Variance table (B). A low Variance % indicates a properly functioning flow control valve.

5. Test Complete

   A high variance number in desired flow range indicates inaccurate rate control.

If system does not control rate accurately, there are a few things to look for and adjust:

• Ensure that correct calibration value is entered for control valve type being used. This value is a starting point and can be fine-tuned.
• The lower the Variance (%), the better the rate controller is able to control a desired flow rate. There are a few issues that might cause variance to be inconsistent:
  • Low pump speed (low flow through selective control valve [SCV]).
  • Tank level. For example, if liquid in tank is low and machine is on a downhill slope, it may not be able to draw in enough product to achieve higher flow rates.
• System operating parameters (for example, tractor speed or pump speed) may need to be adjusted to increase performance at certain levels.
