Circuit configuration for error reporting, having a signal transmitter (1) for issuing error signals, having an error reporting line (46) that is connected with an error report evaluation device (6), having a coupler (2) for galvanic separation of the error reporting line (46) from the signal transmitter (1), and having a power supply (5) for making available an operating voltage for the coupler (2). A connection circuit (3) is provided between coupler (2) and error reporting line (46), which places the error reporting line (46) at a predetermined potential, the error report potential, if the operating voltage of the coupler (2) is insufficient. The connection circuit (3) can furthermore be controlled by the coupler (2), in such a manner that if the signal transmitter (1) issues an error signal, the connection circuit (3) places the error signal onto the error reporting line (46).
