<p>The window lifter includes the microcontroller (400) which is supplied with current from a regulator (402) and connected to an inhibitor (405) and a clock (406). It operates on logic input signals provided by input modules (414,424,434,444) to a selection module (407), and drives (C1-C4) the switching transistors of relays (413,423,433,443) feeding the motors (411,421,431,441) of the control modules (410,420,430,440). Additional relays (451,452) operate two-position contactors connecting the power supply wires (403,404) to a positive terminal (491) and earth in accordance with the polarity of the supply voltage. <IMAGE></p> |
