Disabled
Enabled
[Indexed String]
If CB SC ClsNoDly is Enabled, CB can reclose as leader as soon as the synchro check conditions are satisfied, without waiting for the dead
time to elapse.
This option is sometimes required for the second line end to reclose onto a line with delayed auto-reclosing (typical cycle: first line end
recloses after the dead time with
live bus & dead line, then the second line end recloses immediately with live bus & live line in synchronism).
CB1L SC ClsNoDly 49 A8 Disabled
Disabled
Enabled
[Indexed String]
If CB1L SC ClsNoDly is Enabled, CB1 can reclose as leader as soon as the synchro check conditions are satisfied, without waiting for the dead
time to elapse.
This option is sometimes required for the second line end to reclose onto a line with delayed auto-reclosing (typical cycle: first line end
recloses after the dead time with
live bus & dead line, then the second line end recloses immediately with live bus & live line in synchronism).
