Abstract
A circuit arrangement for controlling a load and for recognizing an interruption in a line to the load includes a measuring resistance connected in series with the load, a device for varying a resistance value of the measuring resistance as a function of a current passing through the load, and a diagnostic device for generating a diagnosis signal if a voltage drop, producible across the measuring resistance by a load current drops below a threshold value.
