Timing member for evaluating signal condition for monitoring and evaluating position switches for lasers, e.g. in robot treatment cells for car body treating

摘要

Time member (10) evaluates signal state, e.g. safety position and working position of operating laser source etc. Logic unit (L1,2) evaluates signal state and energizes release path (20) via output plane (18) when first signal state appears. Logic unit energizes timer (T1,2) which, at change into second state, can be directed into second signal state, i.e. in state, taking over energizing of release path for preset time period. Clock generator (TG1,2) is controlled by logic unit, while its connection and function is specified. Independent claims are included for timing member testing method.
