Abstract
A nominal value is supplied both to a control in a first channel and to a regulator in a second channel parallel to the first channel. The control signal and the regulation signal are transmitted to an apparatus to be regulated. The regulation signal is monitored by a regulator monitoring unit, which generates a shutdown signal when a certain regulation signal level is exceeded and thereby controls or regulates the apparatus into a safe state of operation. In order to effect the regulation, an apparatus output quality is detected by a sensor and the output signal from the sensor is substracted from the nominal value at the input of the second channel. Due to the installation of a control in the first channel, only a single sensor is required for secure two-channel regulation.
