Description of the display window
Setting target cosine:
You can ask your electricity supplier for the target cos, which should be set up at this
point. By default, the target cos is set to 0.95 inductive (see the "Default settings" chap-
ter).
Setting the voltage transformer parameters:
Specify the primary voltage in the U primary submenu, the secondary voltage under U
secondary and the phase allocation of the measuring voltage under Rot.field U. These set-
tings apply to a standard network (voltage Ph-Ph: 400 V primary, 400 V secondary). If you
use a voltage transformer, configure the parameters indicated on the voltage transformer,
e.g. 690V / 100V, as well as the measuring mode, e.g. L12 for measuring voltage connec-
tion between phases L1 and L2.
Setting the discharge time:
Checking or, if necessary, changing the discharge time of the capacitor stages is a very
important menu item. Please make sure that the correct value is set, otherwise the sys-
tem could be damaged!
Setting the maximum stage power per switching cycle (switching opera-
tion):
To quickly compensate missing compensation power or overcompensation, it is possible
to switch identical or different stage powers simultaneously. The number of stages to be
switched simultaneously is determined by the value “Max. stage power per switching
cycle”.
Example:
If there is a missing compensation power of at least 50 kvar and a limit of 50 kvar for this
function, the controller simultaneously switches 2x20 kvar and 1x10 kvar, for example.
The same applies for deactivation in case of overcompensation.
If the stage power limit is set lower than the value of the largest existing stage, the
controller automatically uses the largest capacitor stage available. If the maximum stage
power is set to "0", this function is deactivated and the controller switches each capacitor
stage individually.
