14.8 Limit counter L4UFCNT
14.8.1 Identification
Function description
Limit counter
14.8.2 Application
Limit counter (L4UFCNT) is intended for applications where positive and/or negative sides on a binary
signal need to be counted.
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.
14.8.3 Setting guidelines
The parameters for Limit counter L4UFCNT are set via the local HMI or PCM600.
14.9 Running hour-meter TEILGAPC
14.9.1 Identification
Function Description
Running hour-meter
14.9.2 Application
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.
