Abstract
Abstract The main purpose is to provide an electronic controlling apparatus for controlling the setting members for processing tools and guides of a fish processing machine, which apparatus is easy to handle and designed to guarantee a disturbance-free operation. To this end, there is provided a first module as central computer, a second module comprising a signal amplifier and adapting means, as well as third module designed as a computer periphery circuit. The third module comprises a control unit commonly forming memory, combinatorial and control means, as well as an input part and an output part, which are provided for signal decoupling, signal noise suppressing and signal processing. In particular, each module is designed in the form of a plate, the three plates being interconnected electrically and mechanically for forming a structural unit.
