The CBB sequence is as follows:A071274 V1 ENFigure 112: Three shots with three initiation linesIf the sequence is initiated from the INIT_1 line, that is, the overcurrent protectionhigh stage, the sequence is one shot long. On the other hand, if the sequence is initiatedfrom the INIT_2 or INIT_3 lines, the sequence is two shots long.Table 94:Settings for configuration example 2Setting name Setting valueShot number CBB1 1Init signals CBB1 1 (line 1)First reclose time 0.0s (an example)Shot number CBB2 1Init signals CBB2 6 (lines 2 and 3 = 2+4 = 6)Second reclose time 0.2s (an example)Shot number CBB3 2Init signals CBB3 6 (lines 2 and 3 = 2+4 = 6)Third reclose time 10.0s10.4.3.4 Delayed initiation linesThe auto-reclose function consists of six individual auto-reclose initiation linesINIT_1...INIT 6 and three delayed initiation lines:1MRS756378 D Section 10Control functionsREF615 221Application Manual
