<p>An electronic control unit (13) switches a number of electrical loads (16), especially solenoid valves of a load-switching drive, as a function of the position of various information switches (19). The electronic control unit (13) has a plurality of load lines (17), which each lead to one load (19), and a central unit (15) with a plurality of electronic switches (1). The load lines (17) can in each case be connected via an electronic switch (1) to a supply voltage (14). The electronic switches (1) can in each case be switched by means of a logic signal and have an output (5) for a logic status signal. The logic status signal indicates an open load when the switch is open and a short-circuited load when the switch is closed. In the case of an open, short-circuited switch (1), the status signal suggests an open load. One information line (18) is connected like the load lines (17) via one of the electronic switches (1) to the supply voltage and leads out of the central unit (15). The information line (18) is in each case connected via an information switch (19) to at least one load line (17). <IMAGE></p> |
