Note
•
The scaling of the metered measurands at binary inputs ("Wp(puls)"
and "Wq(puls)") depends on the externally connected pulse
generator.
•
The error status bit of the metered measurands (except of the
operating hours meter) is set after a initial start or restart of the
SIPROTEC device until the second update cycle of the metered
measurands after the reset. This indicates the metered measurands
as "invalid by reset".
•
The error status bit of the metered measurand also signals the
condition of the external fault input of the metered measurands at
binary input (as far as this is parameterized).
