The limit counter provides four independent limits to be checked against theaccumulated counted value. The four limit reach indication outputs can be utilizedto initiate proceeding actions. The output indicators remain high until the reset ofthe function.It is also possible to initiate the counter from a non-zero value by resetting thefunction to the wanted initial value provided as a setting.If applicable, the counter can be set to stop or rollover to zero and continuecounting after reaching the maximum count value. The steady overflow output flagindicates the next count after reaching the maximum count value. It is also possibleto set the counter to rollover and indicate the overflow as a pulse, which lasts up tothe first count after rolling over to zero. In this case, periodic pulses will begenerated at multiple overflow of the function.18.9.3 Setting guidelines GUID-5AECCDBC-7385-4D9F-940C-9D4A0E59B106 v1GUID-DA5DA8D7-4821-4BFB-86CC-28658E376270 v2The parameters for Limit counter L4UFCNT are set via the local HMI or PCM600.18.10 Running hour-meter TEILGAPC18.10.1 Identification GUID-3F9EF4FA-74FA-4D1D-88A0-E948B722B64F v1Function Description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2 devicenumberRunning hour-meter TEILGAPC - -18.10.2 Application GUID-225D8341-2D31-49F1-9B49-571346C0FE26 v1The function is used for user-defined logics and it can also be used for differentpurposes internally in the IED. An application example is to accumulate the totalrunning/energized time of the generator, transformer, reactor, capacitor bank oreven line.Settable time limits for warning and alarm are provided. The time limit foroverflow indication is fixed to 99999.9 hours. At overflow the accumulated timeresets and the accumulation starts from zero again.18.10.3 Setting guidelines GUID-D3BED56A-BA80-486F-B2A8-E47F7AC63468 v1The settings tAlarm and tWarning are user settable limits defined in hours. Theachievable resolution of the settings is 0.1 hours (6 minutes).Section 18 1MRK 506 369-UEN BMonitoring796 Line distance protection REL670 2.2 IECApplication manual
