TripCircuitSup100OpenPos
Figure 3.2-2. Trip circuit supervision when the circuit breaker is open. The
supervised circuitry in this CB position is marked with an extra parallel
line. The resistor device VR10CB offers an active input state for the digital
input although the open coil auxiliary contact is open.
