The operator can run a configuration test to ensure that the system is functioning properly.

IMPORTANT: Always fill the solution tank with clean water to do a proper configuration test.

NOTE: Turn Master Switch OFF at any time to cancel test.

    To begin configuration test:

  1. Select Configuration test from the tests drop-down menu (A).
  2. Turn the Master Switch ON.
  3. Enable Pump checkbox (D) if it is displayed. NOTE: Enable Pump Checkbox (D) will only be displayed if control valve type is PWM and Pump Enable checkbox was selected in PWM settings.
  4. Select Start button (C) on the screen.

    When the test is started, the following procedures are automatically performed in sequence:

  1. The agitator valve (if equipped) is opened for 15 seconds.

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

  3. The flow control valve is tested across the entire range of flow. The results are displayed on in the Flow / Variance table on the screen. A low Variance % indicates a properly functioning flow control valve.

    If the system does not control rate accurately, there are a few things to look for and adjust. (A high variance number in the desired flow range indicates inaccurate rate control.)

  • Ensure to enter the correct calibration value for the control valve type (or a similar valve type) that is being used. This value is a starting point and can be tuned specific to your system.

  • The lower the Variance (%), the better the GreenStar Rate Controller is able to control at a desired flow rate. There are a few issues that might cause the variance on the configuration test to be inconsistent:

    • Low pump speed (low flow through SCV).

    • The amount of liquid in the sprayer tank. For example, if the liquid in the sprayer tank is low and the back of the sprayer is on a down hill slope, it may not be able to draw in enough liquid to achieve the higher flow rates.

  • System operating parameters (example: tractor speed, pump speed, etc.) may need to be adjusted to increase performance at certain levels.
