    What to do if Skov Media Converter stopped after multiple restarts?
    • A
      Ashley LopezAug 11, 2025
      If the Skov Media Converter stops after 5 restart attempts due to the same error within 60 minutes, the possible causes are: * Supply voltage too high. * Power consumption of the motor too high. * Phase errors (L1, L2, L3). * Blocked impeller. * Wrong direction of rotation. * Phase error on the motor supply (U, V, W). * Internal communication error. Suggested solutions: * Measure the supply voltage. * Check for motor errors. * Measure the voltage between the phases. * Remove the blocking. * Invert the rotation direction. * Measure the voltage going to the motor. * Replace frequency converter.

    Why is my Skov Media Converter performance reduced?
    • K
      Kristin SanfordAug 15, 2025
      Reduced performance of the Skov Media Converter can be caused by several factors: * Supply voltage too low. * Internal temperature of the frequency converter too high (>95°C). * Motor current has reached its limit value. * Error in internal circuit of the LPC. * Ripple voltage too high. To resolve this: * Measure the supply voltage. * Check the assembly of frequency converter. * If the negative pressure in the livestock house is too high, check the air inlets. * Replace frequency converter. * Measure the supply phases.
