Description of the display window
Note
Changing the series transformer parameters later on can directly infl uence the
capacitor stages for which the stage power was determined using the auto
confi 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 confi 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.fi 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
specifi ed on the voltage transformer have to be confi 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 diff 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-off in case of overcompensation.
