Configuration Test

causym CAUTION: Running this test will discharge liquid from the nozzles. To avoid injury from exposure to chemicals, use clean water and appropriate personal protective equipment. If necessary, use the master switch to stop application.

This warning occurs when any configuration test is selected on sprayer or liquid fertilizer applications that will discharge liquid.

Configuration Test

 

A-Tests Drop-Down Menu

B-Start Configuration Test Button

C-Master Switch Indicator

  

NOTE: The configuration test is for use on sprayers and liquid fertilizer (not for use on NH3).

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: Master switch must be off to enter data.

To begin configuration test:

1. Select Configuration test from the tests drop-down menu.
2. Turn the Master Spray Switch ON.
3. Press Start button on the screen.
4. Turn Master spray switch off any time to cancel test.

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 turned on 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.

  • Ensure to enter the correct value for the valve type (or a similar valve type) that is being used. This value is a starting point and can be changed.
  • The lower the Variance (%), the better the 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: or the amount of liquid in the sprayer tank.
    • 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 (e.g. tractor speed, pump speed, etc.) may need to be adjusted to increase performance at certain levels.
