Your switches or valves have a safe control that prevent access to dangerous areas?
Our security systems use mechanical key interlocks that garantee, while power to the system is activated, the access doors to the hazardous area remain locked. The key A remains locked in the lock (1) while the process is actived and the line is powered. To access the hazardous area, the disconnector is moved to the OFF position and the bolt A is advanced, locking the disconnector in the open position (OFF). Key A is then picked up and taken to the grounding switch. By inserting and turning the key A in the second lock (2), the operation of the grounding lever is released. Once rotated, the slot on the lever aligns with the next lock lock (3), whose key B is trapped in the lock. Now the key B can be removed from the lock (3), thus locking the lever in the closed position, ensuring that the earth connection can not be interrupted. The system is now disconnected and connected to earth, the B key can be used to operate the access unlocking lock on the dangerous area door to access it.
