Measuring Inputs - Siemens SENTRON PAC3200T Product Manual

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. 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.

Measuring inputs

Current measurement
NOTICE
AC current measurement only.
The device is not suitable for measuring DC current.
PAC3200T is designed for:
● Measuring current of 5 A for connecting standard current transformers. Each current
measuring input can take a continuous load of 10 A. A momentary overcurrent of up to
100 A and a duration of 1 s is possible.
The powerconfig configuration software enables the current direction to be changed
individually for each phase. It is not necessary to change the terminal connections of the
current transformers in the event of connection errors.
