Autoreclose success judgement (ARC-SUCCESS)

If a re-trip does not occur within a set period of time after output of the autoreclosing shot, it is
judged to be an Autoreclose success(ARC-SUCCESS).
The period of time is selected by setting [TSUC] to "0.1-600.0s".

Final trip judgement (ARC-FT)

The following cases are judged ARC-FT(Final Trip) and autoreclose is reset without autoreclose
output.
• Autoreclose initiation when autoreclose initiation is not ready
• Autoreclose initiation after output of the final shot for the setting applied in the multi-shot
mode
• Autorecloce block signal

time after an autoreclose initiation, the autoreclose is forcibly reset.
