CTRL/Latch functions" menuThrough the Blocking Logic submenu, the user can block each delayed threshold using a "BlockLogic" input (refer to Inputs menu). MiCOM P122 & P123 relays have the submenu BlockingLogic 1 and Blocking Logic 2 available for setting.It is possible to enable or disable the “blocking” of most protection functions even if a logicinput has been assigned to that function.Function P120 P121 P122 P123 INFORMATION and COMMENTStI> X X X X Time delayed first phase overcurrentthresholdtI>> X X X X Time delayed second phase overcurrentthresholdtI>>> X X X X Time delayed third phase overcurrentthresholdtIe> X X X X Time delayed first earth overcurrent thresholdtIe>> X X X X Time delayed second earth overcurrentthresholdtIe>>> X X X X Time delayed third earth overcurrentthresholdtIe>>>> X X Time delayed of derived earth overcurrentthreshold.tI2 > X X Time delayed first negative phase sequenceovercurrent thresholdtI2 >> X X Time delayed second negative phasesequence overcurrent threshold.Thermal θ X X Trip threshold for thermal overload.Brkn.Cond X X Broken Conductor trip signal.tAux 1 X X X Aux1 Logic Input delayed by Aux1 timetAux 2 X X X Aux2 Logic Input delayed by Aux2 timetAux 3 X X Aux3 Logic Input delayed by Aux3 timetAux 4 X Aux4 Logic Input delayed by Aux4 timetAux 5 X Aux5 Logic Input delayed by Aux5 time
