Abstract (en)
[origin: WO2011048155A2] In order to operate an electromechanical converter system comprising at least one piezoelectric converter element, if necessary at least an identification element, and control electronics, the useful signals of a certain useful operating range defined by the frequency band and time window, which signals are associated with at least one piezoelectric converter, as well as polling and response signals for identifying and/or checking the function of the converter system are transmitted by means of a line system comprising only one electric signal line. In order to enable a simple and reliable diagnosis possibility of the input circuit for cable breaks, that suitably increases the operational reliability, shortens the troubleshooting times, and simplifies the operation, at least one polling signal located outside of the useful operating range of the converter element is transmitted to the converter system, and at least one characteristic value is formed from the resulting response signal and polled for at least one previously determined criterion, wherein an error message is generated when the criterion is not met.
