Interlocking can be used to help protect personnel and equipment, enforceprocesses, and improve productivity.More information on interlock devices and their use on machinery can be found in ISO 14119, Safety of machinery - Interlockingdevices associated with guards - Principles for design and selection. Further information on trapped key interlocking can befound in the technical specification ISO/TS 19837.Why Mechanical?• Mechanical interlocking can be used to control hazardous energy sources.• A key from one isolation control device can be used in an intermediate transfer (key exchange) device to release keys formultiple guards.• Personnel keys released from access locks can be used to proactively prevent unexpected start up of machinery as per ISO14118.• Mechanical systems reduce wiring and fault masking risk.Key Operated SwitchKey removed, contacts openedKey Exchange DeviceAccess LockA key exchange device allows Key trapped, the intermediate transfer of actuator removedkeys within a system2Access Lock with Personnel KeyAccess key trapped, personnel key removed, guard (door) open
