Unit for compliance with legal requirements for the handling of water-hazardous substances

摘要

The adaptation of machinery and equipment (24) in the handling of water-hazardous substances to the legal requirements under the Water Budget Act WHG requires electrical circuits defined in this context for sensors (18) and actuators (20), which do not follow any standard at the first installation and are only to be realized afterwards with great effort. The present invention therefore concerns one unit (10),which enables standardised insurance to guarantee legal requirements. This unit (10) is particularly suitable for retrofitting existing plants (24). Furthermore, the present invention includes a system (22) with such a unit (10) and a procedure for complying with the legal requirements for the handling of water-hazardous substances.
