Tariffs

NOTE
The parameterization of the tariffs is described in detail in chapter 9.3.5.2. Note the information specified there.
SICAM Q100 supports up to 8 tariffs for power meters for supplied or consumed active energy, reactive
energy, and apparent energy. If the tariff change is controlled, up to 8 tariffs can be set. If tariffs are changed
via binary inputs, up to 2 tariffs can be set. The value of the binary inputs which there is at the time of the
beginning of the subperiod at the binary input is decisive for it.
The tariff is changed via the external interfaces. A time-related tariff change is only possible by a superordinate
system.
Tariff Change on Load-Profile Synchronization
The recorded load profile is always assigned to the current tariff.
If, during a running measuring period, a tariff change is made, for instance, from high to low tariff, this has
initially no effect on the load-profile recording.
The new tariff becomes effective in the load-profile recording and in the power meters of SICAM Q100 only
with the start of the next measuring period.
Tariff Change without Load-Profile Synchronization
If no external and internal synchronization of the load profile is performed, the tariff change becomes effective
immediately. If in the parameterization of the load profile "None" has been selected as a synchronization
source, see chapter 9.3.5.1, a tariff change without synchronization
