Monitoring the supply period

Under "Totalizer functions" (page 62) you can reach two input fields under "Load limits" where the
maximum value of the current supply period or the maximum value of the gas day can be entered. If
these limits are exceeded, an entry will be made in the event archive (see page 17). You can also
set an output contact in case these limits are exceeded (see page 101 et seqq.). If the load limits
are set at zero, no entry will be made in the event archive.

Archive displays

In the periodic archive, the totalizer readings at the end of the relevant period or at the beginning or
end of an event are stored among other things. The periodic archive has a depth of more than
4,400 entries; this corresponds to a period of time of 6 months with a periodic duration of 60
minutes.
In the daily archive, the totalizer readings at the end of a gas day, the maximum periodic values for
the volumes at base and measurement conditions of a month and the maximum daily values for the
volumes at base and measurement conditions of a month are stored among other things.
The archive has a depth of 731 entries; this corresponds to a period of time of 2 years.
In the monthly archive, the totalizer readings at the end of a month and the maximum periodic val-
ues for the volumes at base and measurement conditions of a day are stored among other things.
This archive has a depth of 24 entries; this corresponds to a period of time of 2 years.
All archives have a circular structure which means that if there is an archive overflow, the new entry
will overwrite the oldest one in the archive. For further details about archives, see the description in
this manual from page 13 onwards.
