Pulse valence
With the manufacturer’s settings, the measured
value „sum real power“ is calculated by the real po-
wer of the single phases.
If a pulse valence is assigned to
„digital input 4“
,
the measured value „sum real power“ is calculated
by the incoming pulses of
„digital input 4“
, and
changes at the input are no longer registered in
event memory.
The EMAX program (Option) in UMG505 uses the
measured value „sum real power“ for the control of
disconnection and connection of the consumers and
generators.
