Note
Activate hardware write protection
When connecting the measuring device to a network, it is recommended that the hardware
write protection is activated.
Tariffs
PAC3200T supports 2 tariffs for the integrated energy counters (high tariff and low tariff).
Control of tariff switching
Switching between off-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.
Tariff switching after synchronization
When synchronizing the average power demand values via the communication interfaces or
the digital input, the tariff change will only become effective after expiry of the period. The
power demand is always synchronized by the time. Tariff switching is only done after expiry
of the current period.
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.
