Abstract

Processes and circuitry for the monitoring of final control elements, which was hitherto realised with acoustic or optical warning systems, but has proved insufficient for computer-controlled final control elements, in particular safety devices. In order to achieve a quicker, more reliable and essentially automatic monitoring of computer-controlled final control elements, the output of the computer and the control output of the final control element are both monitored. Certain disturbances can be deduced from the signal probes thus obtained, then either corrected or displayed.
