Scheme logic and settings
2.6.6
The following CH evaluation logics (Figure 2.6-5 to Figure 2.6-7) have the non-directional OC1
and OC2 elements. OC elements can operate when On is set for setting [OC*-EN]. On the
occurrence of a fault, an OC element can pick up the fault; then, it can generate signals
'OC1/2.OPT_CH*' that will be transferred to the output logic (see Figure 2.6-8).
