6.33 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.
Changing the voltage scaling will also influence the nominal power scaling:

10 V-2500 V 1.0-900.0 kW 10.0 V-2500.0 V 10.0 V-2500.0 V
100 V-25000 V 10-20000 kW 100 V-25000 V 100 V-25000 V
1 kV-75 kV 0.10-90.00 MW 0.4 kV-75.00 kV 0.4 kV-75.00 kV
10 kV-160 kV 1.0-900.0 MW 10.0 kV-160.0 kV 10.0 kV-160.0 kV
All nominal values and the primary VT settings must be corrected after the scaling has been
changed in menu 9030.
6.34 Fan logic
The AGC is able to control four different fans. This could e.g. be air supply fans for supplying air to a genset
in a closed enclosure, or radiator fans for switching on and off cooling fans for air coolers.
There are two features in the fan control of the AGC.
1. Priority rearranging depending on running hours of the fans
2. Temperature-dependent start and stop
