The limit counter provides four independent limits to be checked against the
accumulated counted value. The four limit reach indication outputs can be utilized
to initiate proceeding actions. The output indicators remain high until the reset of
the function.
It is also possible to initiate the counter from a non-zero value by resetting the
function to the wanted initial value provided as a setting.
If applicable, the counter can be set to stop or rollover to zero and continue
counting after reaching the maximum count value. The steady overflow output flag
indicates the next count after reaching the maximum count value. It is also possible
to set the counter to rollover and indicate the overflow as a pulse, which lasts up to
the first count after rolling over to zero. In this case, periodic pulses will be
generated at multiple overflow of the function.

15.10.2 Application
GUID-225D8341-2D31-49F1-9B49-571346C0FE26 v1
The function is used for user-defined logics and it can also be used for different
purposes internally in the IED. An application example is to accumulate the total
running/energized time of the generator, transformer, reactor, capacitor bank or
even line.
Settable time limits for warning and alarm are provided. The time limit for
overflow indication is fixed to 99999.9 hours. At overflow the accumulated time
resets and the accumulation starts from zero again.
15.10.3 Setting guidelines
GUID-D3BED56A-BA80-486F-B2A8-E47F7AC63468 v1
The settings tAlarm and tWarning are user settable limits defined in hours. The
achievable resolution of the settings is 0.1 hours (6 minutes).
