Answer Posted / kkrameshkumar
Interlock ckt or generally interlock means providing safe
conditions for startup and running of industrial
machines.For example, In some machines cooling water is
required for startup and lubrication oil pressure should be
available. In this above machine interlocking system is to
be done with cooling water flow and lubrication oil
pressure to avoid any unsafe condition for the machine.The
machine can be started only if both the conditions are
satisfied. During running of the machine if any one fails
then the machine must be tripped. Interlock is necessary in
industrial machines for safe operation of the machine as
well as the process.
