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).

What causes a preload problem in ABB PQFS Industrial Electrical?
- J
  Jennifer CookSep 4, 2025
  If you're encountering a preload problem with your ABB Industrial Electrical system, it means the DC capacitors couldn't be preloaded at startup, possibly because the voltage increase on the DC capacitors during the preload phase isn't high enough. To troubleshoot: * Measure the three line voltages to ensure they are within acceptable limits. * Verify the fuses (PF1 and PF2) and the resistors (R1 and R2) of the preload circuit (A001). * Inspect the DC-bus for traces of damage that may have caused a short circuit on the DC side of the IGBT module or on the DC voltage measurement board.

How to check phase rotation in ABB Industrial Electrical?
- E
  Eddie WagnerSep 5, 2025
  If your ABB Industrial Electrical system indicates a wrong phase rotation, it means the supply network feeding the filter has an incorrect phase sequence. To correct this: * Check the phase rotation of the filter supply. * Measure the three line voltages to ensure they are within 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 and P6-4) for loose connections and component damage. * Check the connections between the auxiliary fuses and the AC voltage measurement connectors (P6-1 to and P6-4).

Why is there no display on PQF-Manager and all LEDs are off in ABB PQFS Industrial Electrical?
- P
  Paula ArnoldSep 6, 2025
  If there is no display on the PQF-Manager and all the indicator LEDs on the electronic card are off in your ABB Industrial Electrical system, it indicates that the active filter (auxiliaries) is not energized or there is no power supplied to the filter. To resolve this: * Check if the protection devices (fuses, disconnector, etc.) feeding the active filter are in good condition. * Verify that the auxiliary fuse box is closed and the fuses are intact. * Check the mains and auxiliary supply voltages.

What does 'Bad CT connection' mean in ABB PQFS?
- B
  bjohnsonSep 7, 2025
  If you're getting a 'Bad CT connection' error with your ABB Industrial Electrical system, it means the automatic CT detection procedure encountered a problem during the CT identification process. Here's how to troubleshoot: * Ensure that the CTs are installed on the supply side of the filter. * Verify that the CTs are not shorted. * Check that the overall CT ratio (including summing CTs) is smaller than 20000/5. * Set up the CTs manually.
