  • Page 38: Messages Of Alarms And Faults

    1.2 MESSAGES OF ALARMS AND FAULTS The faults of the MVW3000 can be subdivided into Alarms (Axxxx) and Faults (Fxxxx). In general, the alarms serve to indicate a situation that, if not corrected, can lead the inverter to a stop by fault. A signalized fault indicates a situation that caused the inverter to be disabled (the main circuit breaker may open or not, depending on the type of fault).

    4 HMI OPERATION The HMI Interface (HMI - Human Machine Interface) provides a series of new resources to the medium voltage frequency inverter MVW3000. They are: Visualization: text and graphic visualization mode. Monitoring: up to 6 parameters can be monitored simultaneously on the screen.

  • Page 66: Starting The Use Of The Hmi

    4.2 STARTING THE USE OF THE HMI The HMI works as the communication master. When the panel is energized, the HMI performs a parameter initialization with the MVC4 board. During this process the firmware versions of the HMI and of the MVW3000 control boards are exhibited.
