FremgangsmÕte for styring av minst en elektronisk forbruker forbundet med en styringsanordning samt en tilhørende krets

摘要

The invention relates to a method for controlling at least one electric consumer which is connected to a control device via electric power lines. A control signal is transmitted to the electric consumers over the electric power lines. The invention provides a method and a more economical corresponding circuit having a simplified construction which make it possible to carry out a data or signal transfer in a secured and simple manner and also over large distances. To this end, the supply voltages transmitted to the electric consumers over the electric power lines are altered for a determined duration by the control device provided for coding the control signal. In the corresponding circuit, at least one element which reduces voltage and/or one switching device is assigned at least to the control device. Said element or switching device is provided for temporarily altering a maximal value of the supply voltage and/or for temporarily interrupting the supply voltage.
