If a modification takes place with an activation date which is different to the existing date and
which is after the current one, the date from the latest modification is taken as the new
activation date.
1.25.3.- Deleting contracts
Deleting a contract leaves all previously defined parameters undefined, and removes all data
referring to it from the screen.
If more than one contract has been defined and is active and one of those belonging to the set
is deleted, a billing close for the contract to be deleted is carried out in that moment and from
then on the information referring to the deleted contract is removed, with no information about
it being displayed other than that relating to any existing billing closures. The rest of the
contracts and the corresponding totalizers are not modified.
1.26.- Load curve
The meter features two load curves, in accordance with the specifications included in Royal
Decree 2018/1997 and its Complementary Technical Instructions. Both load curves store
registers with the number of fields demanded by this standard. The depth of the register is in
both cases 4,000, and the integration period is completely user-configurable. With a period
recorder of 1 hour, the meter can save more than 5 months of load profile.
In the event of voltage drops or clock changes, any gaps produced in the load curve are filled
in with zeros.
An incremental load curve value that does not correspond exactly to the time at which it is
included is marked as invalid. For example, this would be the case for a value that
corresponds to the consumption of several time different times.
If in the request for a load curve quantities that are not registered on the device are requested,
those that are registered will be sent and zero and void will be sent for those that are not
registered.
In both cases, the resolution is 6 digits for the energy values measured in kWh or kvarh (the
same as that in the meter display).
The load profile is initialized if the period of register is modified.
1.27.- Power excesses
These are calculated according to the average power in the last quarter of an hour and the
contracted power, in accordance with RD164/2001.
