Tariffs

SENTRON PAC3200 supports 2 tariffs for the integrated energy counter (on-peak and off-
peak).
Control of tariff switching
Switching between on-peak and on-peak can be controlled via the digital input or the
communication interfaces.
Time-related switching is only possible using a higher-level system. SENTRON PAC3200
does not have its own clock.
Tariff switching after synchronization
When synchronizing the power demand values via the communication interfaces or the
digital input, the tariff change will only become effective after expiry of the period. Without
synchronization, the tariff change takes effect immediately.
The synchronization frame contains the length of the demand period in minutes. The
synchronization command is ignored if the period length sent to the device with the
synchronization frame is different to the length parameterized in the device.
