Why is there no display on PQF-Manager if LEDs are OK in ABB PQFS Industrial Electrical?
- B
  Brandon WallaceSep 3, 2025
  If there is no display on the PQF-Manager of your ABB Industrial Electrical system, but all the indicator LEDs on the electronic cards are functioning properly, the auxiliary transformer might not be set correctly for your network voltage. Try these steps: * Check the tap selection on the auxiliary transformer. * Ensure the supply voltage is within the tolerance range of the nominal filter settings.

What to do if ABB PQFS Industrial Electrical shows DC overvoltage (SW)?
- S
  snyderjonathanSep 1, 2025
  If your ABB Industrial Electrical system triggers the DC software overvoltage protection, here's what you should check: * Verify the connection between the DC voltage measurement connector (P6-5 and P6-7) and the DC capacitors. * Inspect the flat cable connections between the Control Board and the IGBT module. * Analyze the network voltage stability, including amplitude and phase. * Disable reactive power compensation and balancing options to see if the problem persists. * Deselect the high-frequency components to free up DC bus resources and see if the problem persists.

What to do if ABB Water Filtration Systems show 'Unstable mains frequ.'?
- L
  Laura LeeSep 18, 2025
  If your ABB Water Filtration System shows 'Unstable mains frequ.', it indicates that the network frequency is varying too fast. You should measure the network frequency and its variation, and check if they are within the specified limits. Check the phase rotation, especially if there has been modification at the installation. Ensure that the AC voltage is properly measured and conduct the checks described for a ‘Loss of phase’ fault.

What to do if ABB Water Filtration Systems display 'Out of mains freq. Limit'?
- J
  James MartinezSep 16, 2025
  If your ABB Water Filtration System displays 'Out of mains freq. Limit', it means that the system has detected that the network frequency is out of range. You should measure the network frequency to check if it is within the specified limits. Also check the phase rotation, especially if there have been modifications at the installation. Ensure accurate measurement of the AC voltage. Perform the checks outlined for a ‘Loss of phase’ fault.

What to do if ABB PQF-Manager Water Filtration Systems show ‘ACK. FAULT’ and error message ‘Bad parameters’?
- D
  deniseburnsSep 23, 2025
  If the PQF-Manager of your ABB Water Filtration System shows ‘ACK. FAULT’ and gives the error message ‘Bad parameters’, it indicates that the filter parameters entered during commissioning are inconsistent with the filter configuration reported by the controller. You should check the commissioning parameters and correct them where necessary.

How to troubleshoot RMS undervoltage in ABB PQFS Industrial Electrical?
- B
  Brian WaltonAug 28, 2025
  If your ABB Industrial Electrical system is experiencing an RMS undervoltage, it means that the RMS value of the supply voltage, as measured by the AC voltage measurement board, is lower than the acceptable minimum value. To resolve this: * Measure the three line voltages to ensure they are within the specified limits. * Compare the line voltages measured using a voltmeter with those displayed by the filter on the PQF-Manager or PQ-Link. * Ensure that the AC voltage is being correctly measured, referring to the checks for a ‘Loss of phase’ fault.

  Steven WilcoxAug 27, 2025
  If your ABB Industrial Electrical system reports an unbalanced supply, it means the supply network imbalance is out of the acceptable range. To troubleshoot this: * Measure the three line voltages to ensure they are within acceptable limits, including the imbalance limit. * Compare the line voltages measured with a voltmeter to those displayed by the filter (PQF-Manager or PQ-Link). * Ensure that the AC voltage is being properly measured. Refer to the checks for a ‘Loss of phase’ fault.

What causes RMS overcurrent in ABB Industrial Electrical?
- D
  Desiree YoungAug 26, 2025
  If your ABB Industrial Electrical system detects an RMS overcurrent, it means the system has detected an excessive RMS current within the filter. To address this: * Verify that the filter CTs (Current Transformers) are correctly installed and not shorted. * Ensure that the unit current ratings and the programmed order during commissioning match the physical ratings and order. * Check the filter's cooling system and monitor the IGBT temperature using the PQF-Manager. * Try deactivating harmonic and reactive power requirements to see if the problem persists.
