17.9.2 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.
17.9.3 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).
tAlarm and tWarning are independent settings, that is, there is no
check if tAlarm > tWarning.
The limit for the overflow supervision is fixed at 99999.9 hours.
The setting tAddToTime is a user settable time parameter in hours.
