代码 230006: <location>Power unit: Thyristor Control Board

Message value: Drive object: All objects Reaction: OFF2 Acknowledge: IMMEDIATELY Cause: The Thyristor Control Board (TCB) of the Basic Line Module signals a fault. - there is no line supply voltage. - the line contactor is not closed. - the line supply voltage is too low. - line supply frequency out side the permissibl e range (45... 66 Hz). - there is a DC link short-circuit. - there is a DC link short-circui t (during the pre-charging phase). - voltage supply for the Thyristor Control Board ou tside the nominal range (5... 18 V) and line voltage >30 V. - there is an internal fault in the Thyristor Control Board. Remedy: The faults must be saved in the Thyristor Cont rol Board and must be acknowledged. To do this, the supply voltage of the Thyristor Control Board must be switched out for at least 10 s! - check the line supply voltage - check or energize the line contactor. - check the monitoring time and, if required, increase (p0857). - if required, observe additi onal power unit messages/signals. - check the DC link regarding short-circuit or ground fault. - evaluate diagnostic LEDs for the Thyristor Control Board.
