control command to the circuit breaker, either local or remote, also blocks theautoreclosing function via the CBXCBR1-SELECTED signal.The circuit breaker availability for the autoreclosing sequence is expressed using theCB_READY input in DARREC1. The signal, and other required signals, are connectedto the CB spring charged binary inputs in this configuration. The open command fromthe autorecloser is connected directly to binary output X100:PO3, whereas the closecommand is connected directly to binary output X100:PO1.Set the parameters for DARREC1 properly.Check the initialization signals of DARREC1.DARREC1INIT_1INIT_2INIT_3INIT_4INIT_5INIT_6DEL_INIT_2DEL_INIT_3DEL_INIT_4BLK_RECL_TBLK_RCLM_TBLK_THERMCB_POSCB_READYINC_SHOTPINHIBIT_RECLRECL_ONSYNCOPEN_CBCLOSE_CBCMD_WAITINPROLOCKEDPROT_CRDUNSUC_RECLAR_ONREADYACTIVEOR6B1B2B3B4B5B6OOR6B1B2B3B4B5B6OORB1B2OX120_BI3_CB_OPENEDDARREC1_OPEN_CBDARREC1_CLOSE_CBX110_BI3_GAS_PRESSURE_ALARMX110_BI4_CB_SPRING_CHARGEDSECRSYN1_SYNC_OKPHIPTOC1_OPERATEPHHPTOC1_OPERATENSPTOC1_OPERATEPHHPTOC2_OPERATENSPTOC2_OPERATEEFLPTOC1_OPERATEEFHPTOC1_OPERATEPDNSPTOC1_OPERATEARCSARC1_OPERATEARCSARC2_OPERATEARCSARC3_OPERATECBXCBR1_SELECTEDDARREC1_INPRODARREC1_UNSUC_RECLGUID-8569C1BF-C7CF-4853-901E-9C5871B85919 V1 ENFigure 342: Autoreclosing functionThree overvoltage and undervoltage protection stages PHPTOV and PHPTUV offerprotection against abnormal phase voltage conditions.
