Voltage Controller
In case of transfer operation mode, the unit controls frequency and voltage with droop behavior.
For the transfer operation mode, a droop characteristic for the voltage controller is required, otherwise the gen-
erator set would not be able to maintain a stable reactive power being in parallel with the mains.

Frequency controller droop
0 to 20 %
The internally set value for voltage will be reduced by the configured value, when
the maximum reactive power of the generator is reached.
Example: In case of a 200 kW engine power, the reactive power will be 200 kvar as
base value.

Power Factor Controller
In case of transfer and mains parallel operation mode, the power factor controller is required.

ON
................ In a mains parallel operation automatic control of the power factor is
carried out. If there are excessively low currents (secondary current
less than 5 % I
rated
) the power factor cannot be accurately measured.
In order to prevent power swings, the controller automatically locks
the power factor at a set value. The subsequent screens of this func-
tion are displayed.
OFF
.............. Power factor control is not performed, and the subsequent screens of
this function are not displayed.
