Programmable Logic P44x/EN PL/Hb6MiCOM 40 Agile P442, P444 (PL) 6-25Ordinal English Text Description Source1043 Man. Close CB Circuit breaker manual close - order received.'If it is assigned to an opto input in the PSL andenergised the DDB:'Man Close CB' signal will enable theinternal 'SOTF Enable' logic without CB controlactivation. If CB control is activated, SOTF will beenabled by internal detection ('CB close' order managedby CB control).Manual closure of the circuit breaker will force theautorecloser in a lockout logic, if selected in the'Distance schemes / TOR-SOTF Mode') menu.Any fault detected within 500 ms of a manual closure willcause an instantaneous three pole tripping, withoutautoreclose (see Block Autoreclose (BAR) logic)When autoreclose lockout (BAR) is activated, theautorecloser does not initiate any additional reclosingcycle. If autoreclose lockout picks up during a cycle, theA/R close is blocked.This prevents excessive circuit breaker operations,which could result in increased circuit breaker andsystem damage, when closing onto a fault.PSL (IN) CBStatus1044 Man. Trip CB Circuit breaker manual trip - order received.If it is assigned to an opto input in the PSL andenergised, the DDB:'Man Trip CB' signal will inform theprotection of an external CB trip command by the CBcontrol function (if activated).PSL (IN) CBStatus1045 CB Discrepancy CB Discrepancy (one pole open).If it is assigned to an opto input in the PSL andenergised, the DDB:'CB Discrepancy' signal will informthe protection of a pole discrepancy status (one poleopened and the other two poles closed). It must be setto high logical level before Dead time 1 has elapsed – itcan also be generated internally (see Cbaux logic).PSL (IN) CBStatus1046 External Trip A Phase A trip by external protection relay. This input canbe used to update the CB condition monitoring.Opto input is assigned to External Trip A (external Tripcommand issued by main 2 or to initiate the internal A/Rbackup protection). External trip is integrated in theDDB: 'Any Trip'. As for an internal trip, no dwell timer isassociated to it.PSL (IN)1047 External Trip B Phase B trip by external protection relay. This input canbe used to update the CB condition monitoring.Opto input is assigned to External Trip B (external Tripcommand issued by main 2 or to initiate the internal A/Rbackup protection). External trip is integrated in theDDB: 'Any Trip'. As for an internal trip, no dwell timer isassociated to it.PSL (IN)1048 External Trip C Phase C trip by external protection relay. This input canbe used to update the CB condition monitoring.Opto input is assigned to External Trip C (external Tripcommand issued by main 2 or to initiate the internal A/Rbackup protection). External trip is integrated in theDDB: 'Any Trip'. As for an internal trip, no dwell timer isassociated to it.PSL (IN)1049 DIST.
