摘要:The invention relates to the maintenance of safety devices. Valves and similarautomatic mechanical safety devices normally maintaining a fixed position are in dangerof getting stuck, and consequently may not be fully operable in an emergency situation.In a system according to the invention, real-time data indicating the operability of, forexample, a valve actuator, is provided. When a fault is discovered, it can be localized usingonline diagnostic tools. A standby state is continuously maintained, as the unit foractivating the safety function is independent of the unit for monitoring the operability,and the latter is bypassed in an emergency situation.
