Battery-Powered Operation - Siemens SITRANS F MAG 8000 Standard Operating Instructions Manual

Data logger / Consumption alarm
The integrated data logger has 26 logging periods in which data can be stored daily, weekly
or monthly. The logger stores the consumption for totalizer 1 and totalizer 2 in the selected
period. Forward consumption is stored as a positive value and reverse consumption is stored
as a negative value. Alarm and meter status are also stored for the same period to indicate
alarms that have been active, or that revenue data has been influenced in the specific period.
The logged information has a time and date stamp. The data logger never stops storing data
- old data is overwritten following the first in/first out principle, i.e. log 1 is the last stored
information which is moved to log 2 when the next logging is made and so on.
The consumption alarm indicates that the actual consumption on totalizer 1 is above or below
the consumption limits.
Note
Invalid log date
If the log date "00.00.2000" is shown in the device display, the log period was never set.

Battery-powered operation

The MAG 8000 Standard (7ME6810) and MAG 8000 CT (7ME6820) are factory-configured
for 6 years and MAG 8000 Irrigation (7ME6880) for 4 years of typical operation on internal
battery pack (2 D-cell). High or low temperature, frequent use of IrDA communication, high
pulse output rate, high excitation frequency in leakage detection mode, and use of add-on
communication module will reduce actual operation time.
The MAG 8000 power management function controls each power consuming element and
measures the temperature for optimal calculation of remaining battery power capacity.
