Section 15
Monitoring
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.
15.8.3 Setting guidelines
The parameters for Limit counter L4UFCNT are set via the local HMI or PCM600.

Function Description
Running hour-meter
15.9.2 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.
15.9.3 Setting guidelines
The settings tAlarm and tWarning are user settable limits defined in hours. The achievable resolution
of the settings is 0.1 hours (6 minutes).
The limit for the overflow supervision is fixed at 99999.9 hours.
The setting tAddToTime is a user settable time parameter in hours.

tAlarm and tWarning are independent settings, that is, there is no check if tAlarm >
tWarning.
