Volts • Check the external control supply (A1, A2, A3) and reset the starter. • If the external control supply is stable, contact your local supplier for advice.
  • Page 90 1200V soft starter Troubleshooting Display Possible cause/Suggested solution Motor thermistor The motor thermistor input has been enabled and: • The resistance at the thermistor input has exceeded 3.6 kΩ for more than one second. • The motor winding has overheated. Identify the cause of the overheating and allow the motor to cool before restarting.
  • Page 91 Troubleshooting 1200V soft starter Display Possible cause/Suggested solution Phase sequence The phase sequence on the soft starter's input terminals (L1, L2, L3) is not valid. Check the phase sequence on L1, L2, L3 and ensure the setting in parameter 5R is suitable for the installation. Related parameters: 5R, 6P Power loss This trip is not adjustable.
