Operate logicThe OPERATE output of this module can be used for closing the circuit breaker if itis opened for an unknown reason. The OPERATE output is activated immediatelyafter the CB_POSOPEN input becomes active and CB_POSCLOSE inactive. Thepulse length for the OPERATE output signal can be set with the Operate pulse timesetting.The module is disabled if the signal power supply is faulty(SI_PWR_ON = FALSE) or the open command is sent to thebreaker (CB_OPEN_CMD = TRUE).5.7.5 ApplicationThe uncorresponding circuit breaker position means that the actual position of thecircuit breaker’s control switch is unmatched with the real position of the circuitbreaker. In a normal situation, the function is used in cooperation with theautoreclose function (DARREC). The operate signal can start the autoreclosingwhen detecting that the circuit breaker has opened in an unknown situation. If thefunction is used as a stand-alone function when an unknown circuit breaker open isdetected, the function output can be used as an information indication for thesupervision station.5.7.6 SignalsTable 492:UPSCBR Input signalsName Type Default DescriptionCB_OPEN_CMD BOOLEAN 0=False CB open command, commonCB_POSCLOSE BOOLEAN 0=False CB position closedCB_POSOPEN BOOLEAN 0=False CB position openSI_PWR_ON BOOLEAN 0=False Signal power onTable 493:UPSCBR Output signalsName Type DescriptionOPERATE BOOLEAN OperateSection 5 1YHT530004D05 DProtection related functions568 615 seriesTechnical Manual
