  • Page 7: Function

    The product has queries from proximity sensors, which are intended for diagnostics of the internal valves. Performance level d/e in category 3 can be achieved by using proximity sensors S1 and S2. Performance level e in category 4 can be achieved by using an additional proximity sensor S3.
