Energy counters
7.1 How the energy meter works
Changing properties in RUN
You can change the following properties of energy counters in runtime:
● Enable / disable energy counter
● Reset energy counter
● Set initial values for the energy counter
● Change the mode of the energy counter
Automatic reset of the energy counter
The energy counters are automatically reset to "0" when parameter settings relevant to the
energy counter are changed. In the case of phase-specific changing of parameter settings
relevant to the energy counter only the energy counters of the respective phases are reset.
Changing of the following parameters results in resetting of the energy counters:
● Measurement type or range
● Current transformer (primary current/secondary current)
● Voltage transformer (primary voltage/secondary voltage)
● Direction of current
● Full-scale value for energy counter
● Mode of the energy counter (infinite / periodic)
