Nominal Settings
How to Change the Nominal Settings
The nominal settings can be changed to match different voltages and frequencies. The
EMS-GC10 has four sets of nominal values for the generator, and they are adjusted in
parameters.

Parameters
1
6001–6005
2
6011–6015
3
6021–6025
4
6031–6035
There are also two sets of nominal settings for the busbar, they can be adjusted in
parameters.

Parameters
1
6051–6053
2
6061–6063
NOTE: If no busbar voltage transformer is present, the primary and
secondary side values are set to generator nominal value.
NOTE: The possibility to switch between the four sets of nominal
set points is typically used on rental gensets, where switching
between 50 and 60 Hz is required, or switching between different
generator tapping or steering (single phase, three phase, 208/120,
480, ect.
Activation
The switching between the nominal set points, for the generator, can be done in two
ways; digital input & parameter 6006. Switching between busbar parameters sets is
done in parameter 6054.
Digital Input
M-Logic is used when a digital input is needed for switching between the four sets of
nominal settings. Select the required input among the input events, and select the
nominal settings in the outputs.
