ARC1 and ARC2 functions being generating 'ARC1 IN-PROG OR' or 'ARC2-S1 IN-PROG'

signals. The switch [FT-3P FAULT] requires signals of the external relay; PLC connection

points 'RYOP-A, RYOP-B, and RYOP-C' are used to get the signals.

signals are injected, provided 'ARC1 IN-PROG OR' or 'ARC2-S1 IN-PROG' signals is being

If, with regard to the tripped poles of CBs, there is not consistency between the CB#1 and

the CB#2, the ARC function can generate the 'CB1_94TT' and 'CB2_94TT' signals when an

external device is able to detect the consistency; use PLC connection points 'F.CB1_94TT' and

'F.CB2_94TT' for the operation of the inconsistency.

The Start logic can receive a stop signal not to operate the ARC function; use PLC

connection point 'ARC NO ACT'.
