What does it mean when my ABB Controller displays 'Ground fault'?
- L
  Leslie HoltAug 25, 2025
  A ground fault indicates that the sum of the instantaneous line currents in your 3-phase system differs more than the specified value. Examine the motor cables and the motor itself for any issues.

What does it mean when my ABB Controller displays 'Overvoltage'?
- Z
  Zachary JohnsonAug 27, 2025
  An overvoltage error indicates that the main voltage is too high. Perform a check of the main voltage.

What does it mean when my ABB Controller displays 'Under voltage'?
- L
  Laura SanchezAug 27, 2025
  An undervoltage error indicates that the main voltage is too low. Perform a check of the main voltage.

What does 'High current' mean on my ABB PSTX250?
- T
  Tim BennettSep 15, 2025
  A high current fault indicates that a fault current, higher than 8 times the softstarter's rated current, has occurred. Check the circuits and the motor for an insulation fault between phases or a ground fault.

What does 'Auto-restart time-out' mean on my ABB Controller?
- C
  Caitlyn NolanSep 12, 2025
  The auto-restart time-out error means that the time between a trip and an auto-restart attempt has exceeded the configured setting. Review the automatic restart parameters and correct them as needed.

Why does my ABB PSTX250 Controller display 'Too long start time'?
- S
  Summer WarrenSep 14, 2025
  This indicates that the time taken to soft start the motor is longer than the set value. Check the starting conditions and current limit.

How do I fix an ABB PSTX250 Controller that shows a blank screen and no LED is active?
- M
  Melinda AnthonySep 4, 2025
  First, ensure that the supply voltage is properly connected, referring to the circuit diagram. Also check that the RJ45 plug is connected between the HMI and the softstarter, and that the RJ45 network cable is not damaged.

What to do if my ABB PSTX250 Controller motor is humming or starts without a given start signal?
- S
  Samantha WolfeSep 2, 2025
  This issue could be due to a few reasons. If it's a PSTX30...170 model, a bypass relay might be closed due to inaccurate handling. To resolve this, disconnect the operation voltage and the control supply voltage, remove the USB cable if connected, and then reconnect the voltage in the following sequence: first, the control supply voltage on terminals 1 and 2 (refer to chapter 5.1.2), wait 4 seconds, and then connect the operation voltage on terminals L1, L2, and L3. Alternatively, the bypass contactor/relay could be stuck in a closed position, or there might be a shorted thyristor. In either of these cases, it is best to speak to your ABB Sales Office.
