Note

Changing the series transformer parameters later on can directly in uence the

capacitor stages for which the stage power was determined using the auto

con guration mode. This way it is ensured that the stage power is adequately

adjusted in case of a subsequent correction of the transformer parameters.

Manually con gured stages are not taken into account here.

Setting target CosPhi:

You can ask your energy supply company for the target CosPhi, which should

be set up at this point. The target CosPhi is by default set to 0.95 inductive (see

chapter "Default settings").

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. eld U. These settings apply to a standard network (voltage Ph-Ph: 400V pri-

mary, 400V secondary). With measuring voltages of over 500V, the parameters

speci ed on the voltage transformer have to be con gured, e.g. 690V / 100V,

as well as the measuring mode, e.g. L12 for the measuring voltage connection

between the phases L1 and L2.

Setting the discharge time:

Checking or, if required, changing the discharge time of the capacitor stages

is a very important menu item. The discharge time can be set between 20 and

9999 milliseconds for thyristor stages and 0 to 900 seconds for contactor stages.

Please make sure that the correct value is set, otherwise the system could be

damaged!

Setting the maximum stage power per switching operation:

To quickly compensate missing compensation power or overcompensation, it is

possible to switch identical or di erent stage powers at the same time.

The number of stages to be switched simultaneously is determined by the

value “Maximum stage power per switching operation”.

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 e.g. 2x20 kvar and

1x10 kvar.

The same applies to switch-o in case of overcompensation.
