    Trip Log and Event Log. 12.1. Protection Responses When a protection condition is detected, the MV-DS will write this to the event log and may also trip or issue a warning. The soft starter's response depends on the Protection Action setting (parameter group 16).
  • Page 55 Check for other equipment in the area that could be affecting the mains supply, particularly variable speed drives and switch mode power supplies (SMPS). If the MV-DS is connected to a generator set supply, the generator may be too small or could have a speed regulation problem.
  • Page 56 Check the DIP switch settings on the interface PCB. Refer to Ground Current CT Configuration. This trip is not adjustable. The MV-DS has tripped on an internal fault. Contact your local supplier with the fault Internal fault code (X). Related parameters: None During pre-start checks the starter has detected a phase loss as indicated.
  • Page 57 Check that the main contactor closes when a start command is given, and remains closed until the end of a soft stop. Check MV-DS fuses and confirm that all three mains supply phases are present. This trip is not adjustable.
