How to troubleshoot Raven Farm Equipment when pressure and temperature gauge readings indicate NH is not in a liquid state?

  Becky KeySep 8, 2025
  Check that the vapor tubes have been affixed to the applicator knives correctly and that the openings for NH are not plugged or filled with debris. If additives such as N-Serve or ACA have been or are being used with the AccuFlow system, disassemble and clean Vortex cooler chamber. Determine if the operating pressure drop is within tolerances.

  Make sure that all calibration values are correctly entered on the console. Verify the speed display is registering accurately; if not, troubleshoot the speed sensor. In manual control mode, check that the rate display holds a constant value. Ensure hoses connecting the AccuFlow system do not exceed 15’ [4.5 m] of 1-1/2” hoses and use a 1-1/2” breakaway. Replace any street elbows with a conventional elbow and nipple. Verify that the nurse tank has a high flow valve.

  Check the control valve cabling for wear and breaks. Check and clean cable connections as necessary. Check the voltage at the control valve connector by powering on the console, setting the master switch to the ‘on’ position, and setting all products or the console to manual control mode. Hold the increase/decrease switch and check for movement & voltage at the control valve. Verify that the valve is turning by watching the coupler shaft. If the valve does not open or close, replace the control valve motor.

  Check the speed sensor cable and connectors, and the port on the back of the console for loose pins. Clean the pins and sockets on the speed sensor cable connectors. If no speed sensor extension cable is installed, the speed sensor switch assembly may require a replacement; contact a local Raven dealer.

What to do if my Raven AccuFlow Vortex rate reads “0000”?

  First, ensure the speed display is registering accurately. If the speed displays a constant zero value, troubleshoot the speed sensor. Next, verify that the console is registering flow by confirming the total volume display is correct. If the total volume display is incorrect, see the “Rate does not change in either manual or automatic control modes” for resolution.

  First, check the fuses on the back of the console or on the console cable. Then, check the power and ground connections to the battery, ensuring the power leads are connected directly to the battery and not to chassis ground or another power source. Check the operation of the master switch and verify power at valve connectors. If the issue persists, the console may require repair; contact a local Raven dealer.

How to resolve inaccurate speed display with Raven Farm Equipment wheel drive speed sensors?
- C
  Clayton WalkerAug 28, 2025
  First, check if the issue occurs on hard surface roads. If the speed display is accurate on hard surfaces, investigate mounting the speed sensor on a different wheel. If still inaccurate, verify that all magnets are detected by the speed sensor by removing one set of magnets (one red and one black) from the wheel, repositioning remaining magnets directly across from each other, and adjusting the speed cal by entering a value twice as large as the correct speed cal value. Recheck the speed display on a hard surface road. If the speed display is inaccurate with only one set of magnets, replace the bad set. If the speed display is inaccurate with all sets of magnets, replace the speed sensor assembly. Re-enter the original speed cal after testing is complete.

  Check the battery voltage. The console power may be connected to a “dirty” power source. Verify that the power leads from the console cable are connected directly to the battery, not chassis ground or another power source.
