Description
2.1 Performance features
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.
MID-approved
MID-approved devices are included in the portfolio. These devices are suitable for billing the
active energy.
The following actions cannot be carried out on MID-approved devices:
● FW update
● Resetting the secondary energy values
● Parameterization of the voltage input
● Inversion of the direction of current flow
The secondary value of the total active energy is suitable for billing purposes.
The current transformer ratios set have no effect on the secondary total energy value.
The secondary total energy value may already display a counter value upon delivery as a
result of factory device testing.
