9.3.6 Single frequency with
electronic speed control (SF)
The Single frequency option provides an electric
speed controller which improves the output frequency
of the generator at 50 Hz/60 Hz at constant load.
R11 ..... Supply voltage adjust potentiometer
See “Electronic speed regulator”.
R12 ..... Voltage adjustment
Allows to adjust the output voltage.
9.3.7 Electronic speed regulator
The electronic speed regulator makes sure that the
output frequency of the generator is 50 Hz/60 Hz,
independent of the amount of load.
9.3.8 Dual frequency with electronic
speed control (DF)
The Dual frequency with electronic speed control
option allows the unit to work at 50 Hz or at 60 Hz at
constant load. The frequency selection is done by
means of switch S12.
R11 .....Speed adjustment
See “Electronic speed regulator”.
R12 .....Voltage adjustment
Allows to adjust the output voltage.
S12 .....Frequency selector switch (50 Hz/
60 Hz)
Allows to choose the output frequency:
50 Hz or 60 Hz.
9.3.9 Dual voltage (2V)
1 phase - 3 phase
The generator can run in two different modes:
1 phase, lower voltage
When using this selection, the generator provides a
230 V output voltage.
3 phase, higher voltage
When using this selection, the generator provides a
400 V output voltage.
3 phase - 3 phase
The generator can run in two different modes:
3 phase, lower voltage
When using this selection, the generator provides a
230 V output voltage. (IT = active)
3 phase, higher voltage
When using this selection, the generator provides a
400 V output voltage. (ELR = active)
Changing the output frequency is
only allowed when the unit has
stopped.
After changing the output
frequency, adjust the output voltage
by means of potentiometer R12 to
the required value.
The dual voltage option is only
available on 50 Hz units with
Qc1103™ controller.
