month set. The setting range for the target cosine values is the same as the default target
cosine values (ind. 0.5 to cap.0.5).
The summer CosPhi cannot be activated in the Systems-Setting Generator (Power gener-
ation plants).

4. Configuring the capacitor stages
There are two ways of configuring the capacitor stages. The stages can be configured
manually or using the auto configuration mode (a connected current measuring module
is required).
The most important setting to pay attention to is the stage power. The stage power can
be looked up on the nameplate of the stage or the circuit diagram and then programmed
manually. The auto configuration mode then automatically sets this value. However, it has
to be checked and confirmed after each time the auto configuration mode is applied.
Detailed instructions for the auto configuration mode are given
in chapter Extra

Auto configuration mode.
After the stage power has been configured, you have to set the detuning factor. This
factor can be read on the circuit diagram cover sheet or the nameplate of the stage.
If the compensation unit consists of several cabinets, the cabinet assignment should be
adjusted accordingly.
Detailed instructions for this step are given in chapter Start-up under Stages submenu.
5. Function test
A function test should be performed after all values have been programmed step by step,
by disconnecting the controller from the power supply for a few seconds.
The controller should start automatically after it is reconnected to the power supply. If the
cosφ voltage is read in the cosφ act. menu immediately after switching it on, the value
for cosφ should be low and inductive. After approx. 180 seconds, the controller starts to
switch on the individual capacitor stages.
The cosφ, which can be read in the cosφ act. menu, should have risen in comparison with
former values, or it should rise when switching on additional stages. If the compensation
system is designed correctly, the controller should compensate to the set target cos phi
after a while.
