There is also a possibility to activate a preset change of the set operation current viaa binary input (enable multiplier MULTEN). In some applications the operation valueneeds to be changed, for example due to transformer inrush currents.EFPIOC function can be blocked from the binary input BLOCK. The trip signals fromthe function can be blocked from the binary input BLKAR, that can be activatedduring single pole trip and autoreclosing sequences.8.3.8 Technical dataTable 171:EFPIOC technical dataFunction Range or value AccuracyOperate current (5-2500)% of lBase ±1.0% of Ir at I ≤ Ir±1.0% of I at I > IrReset ratio > 95% at (50–2500)% oflBase-Operate time at 0 to 2 x Iset Min. = 15 msMax. = 25 ms-Reset time at 2 to 0 x Iset Min. = 15 msMax. = 25 ms-Critical impulse time 10 ms typically at 0 to 2 xIset-Operate time at 0 to 10 x Iset Min. = 5 msMax. = 15 ms-Reset time at 10 to 0 x Iset Min. = 25 msMax. = 35 ms-Critical impulse time 2 ms typically at 0 to 10 xIset-Dynamic overreach < 5% at t = 100 ms -8.4 Four step residual overcurrent protection, (Zerosequence or negative sequence directionality)EF4PTOC8.4.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberFour step residual overcurrentprotectionEF4PTOC 4(IN>)4 alt4TEF-REVA V2 EN51N/67N1MRK502052-UEN B Section 8Current protection353Technical manual
