<p>The system (10) has input device (20) comprising input terminal (32) and ground terminal (34). An input circuit (70) is connected between input terminal and ground terminal for detecting an input signal. A sensor device (100) is connected to input terminal, and is optionally connected to ground terminal. A supply voltage source (40) is provided for supplying the sensor device with energy. A switched current increasing unit (80) is connected to input terminal and ground terminal, to supply high current to input circuit as a function of applied voltage for adjustable time period.</p> |
