Data logger /
Consumption alarm
34
5. Operation
The integrated data logger has 26 logging periods where data can be stored daily, weekly or
monthly.
The logger stores the real consumption for totalizer 1 and totalizer 2 in the selected period.
Forward calculated consumption is stored as positive values and reverse calculated consumption
is stored as negative values.
Alarm and meter status are also stored for the same period to indicate the alarm that has been
active or revenue data has been influenced in the specific period.
SFIDK.PS.026.D9.02
The logged information has a time & date stamp
and the data logger never stops storing data -
old data is overwritten following the first in/first
out principle. Log 1 is the last stored information,
that is moved to log 2 when the next logging is
made and so on.
The consumption alarm monitors whether the
actual consumption on totalizer 1 is above or
below the consumption limits.
