GE Multilin L60 Line Phase Comparison System 5-2635 SETTINGS 5.6 CONTROL ELEMENTS5the transfer time. When set to “No” the closing command will be blocked by the AR BKR1 BLK signal and the schemewill be sent to lockout by the incomplete sequence timer.• AR TRANSFER 2 TO 1: This setting establishes how the scheme performs when the breaker closing sequence is 2-1and breaker 2 is blocked. When set to “Yes” the closing command will be transferred direct to breaker 1 without waitingthe transfer time. When set to “No”, the closing command will be blocked by the AR BKR2 BLK signal and the schemewill be sent to lockout by the incomplete sequence timer.• AR BKR1 FAIL OPTION: This setting establishes how the scheme performs when the breaker closing sequence is 1-2 and Breaker 1 has failed to close. When set to “Continue” the closing command will be transferred to breaker 2 whichwill continue the reclosing cycle until successful (the scheme will reset) or unsuccessful (the scheme will go to Lock-out). When set to “Lockout” the scheme will go to lockout without attempting to reclose breaker 2.• AR BKR2 FAIL OPTION: This setting establishes how the scheme performs when the breaker closing sequence is 2-1 and Breaker 2 has failed to close. When set to “Continue” the closing command will be transferred to breaker 1 whichwill continue the reclosing cycle until successful (the scheme will reset) or unsuccessful (the scheme will go to Lock-out). When set to “Lockout” the scheme will go to lockout without attempting to reclose breaker 1.• AR 1-P DEAD TIME: Set this intentional delay longer than the estimated de-ionizing time after the first single-pole trip.• AR BREAKER SEQUENCE: This setting selects the breakers reclose sequence: Select “1” for reclose breaker 1 only,“2” for reclose breaker 2 only, “1&2” for reclose both breakers simultaneously, “1-2” for reclose breakers sequentially;Breaker 1 first, and “2-1” for reclose breakers sequentially; Breaker 2 first.• AR TRANSFER TIME: The transfer time is used only for breaker closing sequence 1-2 or 2-1, when the two breakersare reclosed sequentially. The transfer timer is initiated by a close signal to the first breaker. The transfer timer trans-fers the reclose signal from the breaker selected to close first to the second breaker. The time delay setting is based onthe maximum time interval between the autoreclose signal and the protection trip contact closure assuming a perma-nent fault (unsuccessful reclose). Therefore, the minimum setting is equal to the maximum breaker closing time plusthe maximum line protection operating time plus a suitable margin. This setting will prevent the autoreclose schemefrom transferring the close signal to the second breaker unless a successful reclose of the first breaker occurs.• AR BUS FLT INIT: This setting is used in breaker-and-a-half applications to allow the autoreclose control function toperform reclosing with only one breaker previously opened by bus protection. For line faults, both breakers must openfor the autoreclose reclosing cycles to take effect.
