4.8 Energy
Warning!
After modification of energy parameters, the energy meters must be reset
otherwise all further energy measurements could be incorrect.
Active tariff
When active tariff is set, one of the tariffs (up to four) is defined as active.
Common energy exponent
Common energy exponent defines minimal energy that can be displayed on the energy counter.
On the basis of this and a counter divider, a basic calculation prefix for energy is defined (−3 is
10
−3
Wh = mWh, 4 is 10
4
Wh = 10 kWh). A common energy exponent also influences in setting a
number of impulses for energy of pulse output or alarm output functioning as an energy meter.
Define common energy exponent as recommended in table below, where counter divider is at
default value 10. Values of primary voltage and current determine proper Common energy
exponent.
Current
Voltage
1 A 5 A 50 A 100 A 1000 A
110 V −1 0 1 1 2
230 V 0 0 1 2 3
1000 V 0 1 2 3 4
30 kV 2 2 3 4 4*
* − Counter divider should be at least 100
Counter divider
The counter divider additionally defines precision of a certain counter, according to settings of
common energy exponent.
An example for 12.345kWh of consumed active energy:
Common energy exponent 0 2 2
Counter divider 1 1 100
Example of result, displayed 12.345 kWh 12.3 kWh 0.01 MWh
4.9 Inputs and outputs
Module settings depend on built-in modules.
Analog output module
Each of up to four analog outputs is fully programmable and can be set to any of 6 full-scale
ranges. Within each of those 6 ranges, other required output ranges can be set. For example,
4 … 20 mA range can be set when ± 20 mA full-scale range is selected:
