Hello Control People and Engineers!
I'm digging a bit into safety circuits and safety relays and trying to analyze some simple safety circuits.
My problem is that I don't know a good method for describing and analyzing the functions of the circuits.
Here's the circuit I'm trying to analyze (the simplest safety circuit)

I've tried a bit with boolean expressions like these:
K1 = NOT(SW1) AND (K2 OR K1)
K2 = S1 * NOT(KL1) AND NOT(K1)
... but it seems like it's not the right way to do it, since this circuit is sequential.
Should I use flow diagrams or how would you analyze such a circuit?
Thanks in advance!
Peter
