Hello, following a description of the failure message “Bypass part fault” =defective -> bypass contactor welded or not closed. If the bypass contactor is welded the failure can detected if the current continue flow or on the missing zero crossings of the voltage. If the bypass contactor not close ( e.g. wires not connected) the zero crossings of the voltage are further present and the current flow further via the thyristors, not via the open bypass contactor. if the error still exists contact the Siemens technical support.
