What to do if ABB Industrial Electrical shows RMS overvoltage?
- E
  Ernest TaylorAug 26, 2025
  If your ABB Industrial Electrical system is showing an RMS overvoltage, it indicates that the RMS value of the supply voltage, as measured by the AC voltage measurement board, exceeds the acceptable maximum. Here’s how to troubleshoot: * 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. * Make sure that the AC voltage is being correctly measured.

What to do if there is a loss of phase in ABB Industrial Electrical?
- T
  Travis TaylorAug 23, 2025
  If you're experiencing a loss of phase in your ABB Industrial Electrical system, it means the system has detected a loss of supply on at least one phase. Here's what you can do: * Measure the three line voltages to ensure they are within acceptable limits. * Compare the line voltages measured with a voltmeter to those displayed by the filter (PQF-Manager or PQ-Link). * Inspect the AC voltage measurement connectors (P6-1 to P6-4) for any loose connections or component damage. * Check the connections between the auxiliary fuses and the AC voltage measurement connectors (P6-1 to P6-4). * Review the filter parameters.

What causes DC overvoltage (HW) in ABB PQFS Industrial Electrical?
- C
  Cynthia YoungSep 2, 2025
  If the DC hardware overvoltage protection has been triggered in your ABB Industrial Electrical system, it means that the DC voltage has exceeded the hardware limit. To troubleshoot: * Check the connection between the DC voltage measurement connectors (P6-5 and P6-7) and the DC capacitors. * Verify the flat cable connections between the Control Board and the IGBT module. * Analyze network voltage stability (amplitude and phase). * Disable reactive power compensation and balancing options to see if the problem persists. * Deselect the high frequency components to free DC bus resources and to see if the problem persists.

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.

How to troubleshoot transient overvoltage (SW) in ABB PQFS Industrial Electrical?
- M
  Mary JohnsonSep 3, 2025
  If your ABB Industrial Electrical system is experiencing a software transient network overvoltage, here's how to address it: * If the errors occur sporadically and the system recovers, no action may be needed. * If the system frequently encounters transient errors: * Measure the line voltages with a device capable of measuring peak voltage (e.g., scopemeter) and ensure the values are within acceptable limits. * Measure the RMS value of the network voltage and compare it with the line voltages displayed by the filter (PQF-Manager or PQ-Link).
