7.28 Nominal settings
7.28.1 How to change the nominal settings
The nominal settings can be changed to match different voltages and frequencies. The controller has four
sets of nominal values for the generator, and they are adjusted in menus 6000 to 6030 (Nominal settings 1 to
4). There are also two sets of nominal settings for the busbar, they can be adjusted in menus 6050 to 6060.
If no busbar voltage transformer is present, the primary and secondary side values are set to
generator nominal value.
The possibility to switch between the four sets of nominal setpoints is typically used on rental
gensets, where switching between 50 and 60 Hz is required.
Activation
The switching between the nominal setpoints can be done in two ways; digital input or menu 6006.
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.
Example:
Event A
Event B
Event C

Menu settings
In menu 6006 the switching is made between settings 1 to 4 simply by choosing the desired nominal setting.
7.29 Scaling
Default voltage scaling is set to range 100 V-25000 V (menu 9030). To be able to handle applications above
25000 V and below 100 V, it is necessary to adjust the input range so it matches the actual value of the pri-
mary voltage transformer. This makes it possible to support a wide range of voltage and power values.
Setup of the scaling can be done in menu 9030 from the display.
