Regulation Principle - Deif Multi-line 2 Description Of Options

GPC, PPU
Input setup
The scaling of the transducer can be adjusted in the input setup, menu 3520.
This can only be adjusted from the USW.
The input can only be scaled in percent.
If the scaling is not done according to the specific application, the regulation
will work but the display reading will be false.
Principle
When the regulation is started, the multi-line 2 will regulate the power according to the water
level and the fixed power set point.
The below drawing illustrates how the regulation works:
1. The power set point is set to 90% (menu 4041).
2. The water level transducer gives 20mA when the water level is above 180% (menu
404X).
3. The water level transducer gives 4mA when the water level is below -60% (menu 404X).
When the turbine is running and the regulation is activated, the power of the
gen-set will depend on the available water level.
