Not sure what you refer to with"ckt" but interlocks is all
about starting a application or machine safely.
For example if you want to start up a compressor the
discharge valve must be closed, the recycle valve must be
open, the guide vanes must be at 10%, there must be power
available, there must be air available, the oil must be at
60 degrees, the cooling water recycle pump must be running
and so on. The local control system(PLC) will only allow you
to start the compressor when all these interlocks have been met.
Good luck
