Electrical kirk key system.

Therefore the key is free. To close any one device the key is inserted. Both devices are shown open. Key interlocks avoid the limitations of electrical interlocking and the restrictions of mechanical interlocking by making use of easily portable keys carried in sequence from one interlock to the next.

The fundamental principle of interlocking disabling one electrical or mechanical function unless some other function or functions is in a particular state can be achieved in many ways. Kirk releases new coupler interlock system the coupler interlock system is an electromechanical interlock that is suitable for controlling access to tubular bulk material transfer systems such as those used for silo storage mitigating the risk of lost material and cross contamination during the loading or unloading process. Once the power has been turned off the key can be withdrawn and used in the next sequence of operation such as unlocking an access hatch or allowing valves to be operated. Key interlocked circuit breakers and bolted pressure switches are designed to be operated in a specific sequence.

For example to prevent access to the inside of an electric kiln while it is operating a trapped key system may be used to interlock a disconnecting switch and the kiln door. With the interlocks arranged as shown only one key is required in the interlocking system.

Our rotary trapped key interlock switches are used for electrical isolation of machinery to improve safe access and also as teach boxes in robot cells. A kirk key interlocking system eliminates mistakes with no dr. Using kirk interlocks when connecting ship s power cables to on shore power will ensure that the cables are properly coupled to the junction box before energizing. Whenever the kiln power switch is turned on the key is automatically held by the interlock and cannot be manually removed.

This process is also known as cold ironing.
