DESCRIPTION
Maximum waiting time to enable CB Closing by auto-reclose.
Input DDBs (436/437) are used for CB1 Healthy & CB2 Healthy respectively to enable CB1 and CB2 Close by auto-reclose.
If the set time runs out with the input DDB: CBx Healthy low (= 0), alarm AR CBx Unhealthy (DDB307 or 329 for CB1 & CB2 respectively) is set
and the CBx auto-reclose sequence is cancelled.
AR CheckSyncTime 49 70 5
From 0.01 to 9999 in steps of 0.01
[Courier Number (time-seconds)]
Maximum waiting time for relevant signals CB1L SCOK or CB1F SCOK from system check logic, to enable CB1 Close by auto-reclose.
Same waiting time setting applies to input signals CB2L SCOK or CB2F SCOK to enable CB2 Close by auto-reclose.
If the set time runs out with the input signal CBx SCOK low (= 0), System Check Synchronization fail alarm AR CBx NO C/S (DDB 308 or 330 for
CB1 & CB2 respectively) is set and the CBx auto-reclose sequence is cancelled.
Z1 AR 49 72 Initiate AR
Initiate AR
Block AR
[Indexed String]
Setting that determines impact of instantaneous zone 1 on AR operation.
(Only in models with distance option)
Dist Aided AR 49 74 Initiate AR
Initiate AR
Block AR
[Indexed String]
Setting that determines impact of the aided distance schemes tripping on AR operation.
(Only in models with distance option)
Z2T AR 49 75 Block AR
No Action
Initiate AR
Block AR
[Indexed String]
Setting that determines impact of time delayed zone 2 on AR operation. Set Initiate AR if the trip should initiate a cycle, and Block AR if a
time delayed trip should cause lockout. Set No action if Zone 2 tripping should exert no specific logic control on the recloser.
