PLC setting sample for autoreclosing (UARCSW application)
If the follower Terminal is reclosed after checking the leader Terminal reclosed in the autoreclose
mode "SPAR", the leader Terminal is assigned to the signal number 1 with signal name
"CONSTANT_1" and the follower Terminal assigned to the signal number 498 with signal name
"3PLL" as shown in Figure T-2.1.
In this case, the reclosing condition of [SPR.L-REQ] is the difference between the leader Terminal
and the follower Terminal. If the same setting is required for the reclosing condition of
[SPR.L-REQ], set the PLC using the [UARCSW] described in 2.10.2 as follows:
The reclose condition can be changed by the position of [UARCSW].
[UARCSW] = P1: (No condition for reclosing)
[UARCSW] = P2: 3PLL (Three phase live line condition for reclosing)
The [UARCSW] is effective when the reclosing condition of PLC setting has the difference
between the leader Terminal and the follower Terminal.
