The output for each limit isactivated when the counted value reaches that limit.Overflow indication is included for each up-counter.16.9.3 Operation principleGUID-4D58423F-329C-4553-9FAF-E55A368849A5 v2Limit counter (L4UFCNT) counts the number of positive and/or negative sides on thebinary input signal depending on the function settings. L4UFCNT also checks if theaccumulated value is equal or greater than any of its four settable limits. The four limitoutputs will be activated relatively on reach of each limit and remain activated until thereset of the function. Moreover, the content of L4UFCNT is stored in flash memoryand will not be lost at an auxiliary power interruption.1MRK 511 408-UUS A Section 16MonitoringPhasor measurement unit RES670 2.2 ANSI 585Technical manual
