Operation counterphase fault trip counter runningOperation counterApplicationThis counter displays the number of closing operationsperformed by the breaking device. This data gives anindication of the degree of equipment mechanicalwear and facilitates equipment maintenance.OperationPhase fault trip counterApplicationThis counter displays the number of opening operations for which breakingperfomances were required (phase-to-phase short-circuits, breaking of strongcurrents). This data gives an indication of equipment electrical wear and facilitatesequipment maintenance.Operationinput I1KP19access to pocket terminal:- reading of counter C1- reset by contact KP19counter C1countingresetThe event counter C1 increments with each rising edgeof input I1, the image of the closed position of thebreaking device.input I2input I17O/C trippingdir.
