Figure 3.4-1. Trip circuit supervision when the circuit-breaker is closed.
The supervised circuitry in this CB position is double-lined. The digital
input is in active state. The value for R1 in this application is 3k3 and 2W.
These can be calculated from the resistance and voltage operating range of
the coil of K1 and the tolerance of the wetting voltage.
