trip logics and gas pressure alarm and circuit breaker spring charging. The OKPOSoutput from the DCSXSWI block defines if the disconnector or breaker truck isdefinitely either open/in test position or close/in service position. This, together withthe open earthing switch and non-active trip signals, activates the close-enable signalto the circuit breaker control function block. The open operation is always enabled.The auto-recloser close command signals are directly connected to the output contactPO1 (X100:6-7).If the ENA_CLOSE signal is completely removed from the breakercontrol function block CBXCBR with SMT, the function assumesthat the breaker close commands are allowed continuously.The ITL_BYPASS input can be used, for example, to always enable the closing ofthe circuit breaker when the circuit breaker truck is out in the test position, despite ofthe interlocking conditions being active when the circuit breaker truck is closed inservice position.The circuit breaker condition monitoring function (SSCBR) supervises the circuitbreaker status based on the binary input information connected and measured currentlevels. The function introduces various supervision methods. The correspondingsupervision alarm signals are routed to LED 8.Section 3 1MRS756378 DREF615 variants78 REF615Application Manual
