When [ARC-CCB] is set to "MPAR", the center breaker is also reclosed in the multi-phase
autoreclose mode at the time of the TMPR2 setting.
When [ARC-CCB] is set to "OFF", autoreclose does not start for the center breaker.
The scheme switch [ARC-CCB] used in single-phase autoreclose and single- and three-phase
autoreclose is invalid when multi-phase autoreclose is selected as a reclose mode.
The interlinking check scheme for two-breaker autoreclose is shown in Figure 2.15.2.5. Local
interlink check signals CBDS-A, -B and –C are originated by ORing the busbar and center
breaker conditions.
The scheme switch [ARC-SUC] is used to check the autoreclose succeeds. If all three phase CB
contacts have been closed within TSUC time after ARC shot output, it is judged that the
autoreclose has succeeded (AS). If not, it is judged that the autoreclose has failed (AF), and
becomes the final tripping (FT).
The relay provides the user configurable switch [UARCSW] with three-positions (P1, P2, P3) to
be programmed by using PLC function. Any position can be selected. If this switch is not used
for the PLC setting, it is invalid. The setting example is shown in Appendix S.
