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.
16.8.3 Setting guidelines
The parameters for Limit counter L4UFCNT are set via the local HMI or PCM600.

16.9.1 Identification
Function Description
Running hour-meter
16.9.2 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.
16.9.3 Setting guidelines
The settings
resolution of the settings is 0.1 hours (6 minutes).

identification
TEILGAPC
tAlarm and tWarning are user settable limits defined in hours. The achievable
tAlarm and tWarning are independent settings, that is, there is no check if tAlarm >
tWarning .
