The Auto init parameter defines which INIT_X lines are activatedin the auto-initiation. The default value for this parameter is "0",which means that no auto-initiation is selected.A070871 V1 ENFigure 388: Example of an auto-initiation sequence with synchronization failurein the first shot and circuit breaker closing failure in the second shotIn the first shot, the synchronization condition is not fulfilled (SYNC is FALSE).When the auto wait timer elapses, the sequence continues to the second shot.During the second reclosing, the synchronization condition is fulfilled and the closecommand is given to the circuit breaker after the second reclose time has elapsed.After the second shot, the circuit breaker fails to close when the wait close time haselapsed. The third shot is started and a new close command is given after the thirdreclose time has elapsed. The circuit breaker closes normally and the reclaim timestarts. When the reclaim time has elapsed, the sequence is concluded successful.9.4.6.2 SequenceThe auto reclose sequence is implemented by using CBBs. The highest possibleamount of CBBs is seven. If the user wants to have, for example, a sequence ofthree shots, only the first three CBBs are needed. Using building blocks instead offixed shots gives enhanced flexibility, allowing multiple and adaptive sequences.Each CBB is identical. The Shot number CBB_ setting defines at which point in theauto-reclose sequence the CBB should be performed, that is, whether the particularCBB is going to be the first, second, third, fourth or fifth shot.During the initiation of a CBB, the conditions of initiation and blocking arechecked. This is done for all CBBs simultaneously. Each CBB that fulfils theinitiation conditions requests an execution.The function also keeps track of shots already performed, that is, at which point theauto-reclose sequence is from shot 1 to lockout. For example, if shots 1 and 2 havealready been performed, only shots 3 to 5 are allowed.Additionally, the Enable shot jump setting gives two possibilities:Section 9 1YHT530004D05 DControl functions714 615 seriesTechnical Manual
