Autoreclose initiation
Programmable binary input ARC-READY(CB& 63condition) is alive and Reclaim time TRDY
has elapsed and Scheme switch [ARCEN] is set to "On," then autoreclose initiation is ready. The
reclaim time is selected by setting [TRDY] to "0.0-600.0s".
ARC INIT(Autoreclose initiation) can consist of the following trips. Whether autoreclose initiation
is active or not is selected by setting [∗∗∗∗-INIT].
- OC1 to OC4 trip
- EF1 to EF4 trip
- SEF1 to SEF4 trip
Setting [∗∗∗∗-INIT] = NA / On / Block
EXT TRIP(External autoreclose initiation) is an autoreclose initiation via programmable binary
inputs. Whether autoreclose initiation is active or not is selected by setting [EXT-INIT].
Setting [EXT-INIT] = NA / On / Block

Autoreclose shot output (ARC-SHOT)
The maximum number of autoreclosing shots is selected by setting [ARC-NUM].
Setting [ARC-NUM] = S1/S2/S3/S4/S5
The passage of TD∗ time(Dead timer) is selected for each shot number by setting [TD∗] to
"0.01-300.00s."
The command output pulse(One shot) time is selected by setting [TW] to "0.01-10.00s."
NA: Autoreclose initiation is not active.
On : Autoreclose initiation is active.
Block: Autoreclose is blocked.
