8.6.2 Control variable
If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module and using the "single-phase" regulation mode, this parameter
can be used to select the phase used for voltage regulation. You can select
the following options:
▪ L1/N or L1/L2
▪ L2/N or L2/L3
▪ L3/N or L3/L1
To set the control variable, proceed as follows:
1. Go to Settings > Parameters > Measurement > Control variable.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.
8.6.3 Regulation mode
If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module, you can use this parameter to set whether you want 1-phase
voltage regulation or voltage regulation to the average value of the 3 phases.
You can select the following options:
▪ Single-phase: Voltage is automatically regulated to one selected phase.
Limit value monitoring, line drop compensation, and parallel operation
also take place on the selected phase using the circulating reactive cur-
rent minimization method.
▪ Average value regulation: Voltage is automatically regulated to the aver-
age of the 3 phases. Limit value monitoring, line drop compensation, and
parallel operation also take place using the circulating reactive current
minimization method to the average of the 3 phases.
If you activate the average value regulation option, automatic voltage regu-
lation is blocked should the voltage or current measurement of one of the 3
phases fail.
To set the regulation mode, proceed as follows:
1. Go to Settings > Parameters > Measurement > Regulation mode.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.
