Circuit breaker monitoring SSCBRThe circuit breaker condition monitoring functionSSCBR is used to monitor different parameters ofthe circuit breaker. The breaker requiresmaintenance when the number of operations hasreached a predefined value. For proper functioningof the circuit breaker, it is essential to monitor thecircuit breaker operation, spring charge indication,breaker wear, travel time, number of operationcycles and accumulated energy. The energy iscalculated from the measured input currents as asum of I^2 t values. Alarms are generated when thecalculated values exceed the threshold settings.The function contains a blocking functionality. It ispossible to block the function outputs, if desired.11. MeteringPulse counter logic PCGGIOPulse counter (PCGGIO) function counts externallygenerated binary pulses, for instance pulses comingfrom an external energy meter, for calculation ofenergy consumption values. The pulses arecaptured by the BIO (binary input/output) moduleand then read by the PCGGIO function. A scaledservice value is available over the station bus.Function for energy calculation and demandhandling ETPMMTROutputs from the Measurements (CVMMXN)function can be used to calculate energyconsumption. Active as well as reactive values arecalculated in import and export direction. Valuescan be read or generated as pulses. Maximumdemand power values are also calculated by thefunction.12. Human Machine interfaceLocal HMIANSI12000175 V1 ENFigure 6. Local human-machine interfaceThe LHMI of the IED contains the following elements:• Display (LCD)• Buttons• LED indicators• Communication portThe LHMI is used for setting, monitoring andcontrolling.The Local human machine interface, LHMI includesa graphical monochrome LCD with a resolution of320x240 pixels. The character size may varydepending on selected language. The amount ofcharacters and rows fitting the view depends on thecharacter size and the view that is shown.The LHMI is simple and easy to understand. Thewhole front plate is divided into zones, each with awell-defined functionality:• Status indication LEDs• Alarm indication LEDs which can indicate threestates with the colors green, yellow and red,with user printable label. All LEDs areconfigurable from the PCM600 tool• Liquid crystal display (LCD)• Keypad with push buttons for control andnavigation purposes, switch for selectionbetween local and remote control and reset• Five user programmable function buttons• An isolated RJ45 communication port forPCM600Bay control REC650 ANSI 1MRK 511 265-BUS BProduct version: 1.230 ABB
