Autoreclose start requirement
Using PLC function, various autoreclose start requirements can be designed. In Figure 2.15.2.8,
a reclose start requirement for "SPAR", "TPAR", "SPAR&TPAR" or "MPAR" can be
respectively assigned to the following signals by PLC:
"SPAR":
"TPAR":
"SPAR&TPAR":
"MPAR":
The default setting for the follower CB autoreclose start requirement is as follows:
Reclose start
Default setting
requirement
"SPAR"
[SPR.F-ST.REQ] = CONSTANT_1
"TPAR"
[TPR.F-ST.REQ] = ARC-SET or CCB-SET
"MPAR"
[MPR.F-ST.REQ] = CONSTANT_1
Autoreclose requirement
The autoreclose requirement can be designed by assigning a reclose requirement to the signals
[SPR.F-REQ], [TPR.F-REQ] and [MPR.F-REQ] same as above.
The default setting for the follower CB autoreclose requirement is as follows:
Reclose requirement
"SPAR"
"TPAR"
"MPAR"
Others
If the autoreclose start requirement is designed such as starting the follower CB in no-ready
condition of the leader CB, it is assigned to the signal [R.F-ST.REQ].
By assigning the autoreclose start requirement to the signal [R.F-ST.REQ], both the leader CB
and the follower CB are set the same dead time. The reclose requirement is assigned to the
signals [SPR.F2-ST.REQ], [TPR.F2-ST.REQ] and [MPR.F2-ST.REQ].
The default setting for the follower CB is as follows:
Requirement
Reclose requirement
Reclose start requirement
"SPAR"
"TPAR"
"MPAR"
[SPR.F-ST.REQ]
[TPR.F-ST.REQ]
[SPR.F-ST.REQ], [TPR.F-ST.REQ]
[MPR.F-ST.REQ]
Default setting
[SPR.F-REQ] = CONSTANT_1
[TPR.F-REQ] = SYP-ON
[MPR.F-REQ] = CONSTANT_1
Default setting
[R.F-ST.REQ] = CONSTANT_0
[SPR.F2-ST.REQ] = CONSTANT_0
[TPR.F2-ST.REQ] = CONSTANT_0
[MPR.F2-ST.REQ] = CONSTANT_0

Remarks
No condition
ARC-SET becomes "1" when the leader CB is
reclosed.
CCB-SET becomes "1" when [ARC-M]=M2 or
M3 and [ARC-CCB]=TPAR setting.
