4.11.3 Example of automatic sequence operation
Figure 4.11-2 exemplifies some sequence logic programmed using the PLC function; the logic
is coded to operate two disconnector (DS1 and DS2) and a circuit breaker (CB). The logic can
provide an instruction to close DS1 (i.e., device #2), close DS2 (i.e., device #3), and then close
the CB (i.e., device #1) in a prescribed order.
