7.14.2 Changing the Voltage Limiting Values for the Generator
Significance of the voltage limits:
The voltage limiting values determine the range within which the generator voltage is allowed to
fluctuate. When the off-grid inverter switches to the generator, the stand-alone grid will also fluctuate
within this range.
A breach of the set voltage limiting values leads to disconnection of the generator, to disconnection
of the line conductor from the stand-alone grid or to the generator not being switched on.
1. Switch to expert mode (see Section 7.6).
2. Select the 234.01 GnVtgMin parameter and set it to the minimum generator voltage.
3. Select the 234.02 GnVtgMax parameter and set it to the maximum generator voltage.
7.14.3 Changing the Frequency Limiting Values of the Generator
Voltage
Significance of the frequency limits:
The frequency limiting values determine the range within which the frequency of the generator voltage
is allowed to fluctuate. When the off-grid inverter switches to the generator, the stand-alone grid will
also fluctuate within this range.
A breach of the set frequency limiting values leads to disconnection of the generator, to disconnection
of the line conductor from the stand-alone grid or to the generator not being switched on.
1. Switch to expert mode (see Section 7.6).
2. Select the 234.04 GnFrqNom parameter and set it to the rated frequency of the generator
voltage.
3. Select the 234.05 GnFrqMin parameter and set it to the minimum frequency of the generator
voltage.
4. Select the 234.06 GnFrqMax parameter and set it to the maximum frequency of the generator
voltage.
