Applications

KL dual key bolt interlocks are used as a part of a safety system. A typical application is where the electrical and pneumatic supplies to the machine are switched on and the access doors to the hazardous area are locked closed.

Keys A and B are trapped in the KL bolt interlock, preventing access to the machine area. To enter the area, the pneumatic supply must be turned off. Turning the keys in the KL bolt interlock will extend its bolt. The released keys ensure the bolt remains in extended position locking off the disconnector. The released keys can now be taken to the machine area to gain access via the AI access interlocks.

The disconnector cannot be switched on until both access doors are locked closed and both keys replaced in the KL bolt interlock.
