Compressed-Air System Having a Safety Function and Method for Operating Such a Compressed-Air System
Publication number: 20170051768Abstract: A compressed-air system having a safety function and a method for operating such a compressed-air system. The compressed-air system contains two working valves, which each can selectively assume an aerating position that aerates a load and a venting position that vents the load. Both working valves are redundantly connected on the output side to the load by means of a separating device. The separating device allows one or the other of the working valves to be separated, while the aeration of the load is maintained, in order to subject the one or the other working valve to an examination of the switching function of the one or the other working valve.Type: ApplicationFiled: March 6, 2015Publication date: February 23, 2017Applicant: Festo AG & CO.
