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 measurement voltage under Rot.field U. These settings apply to a standard network
(voltage Ph-Ph: 400V primary, 400V secondary). With measurement voltages of over 500V, the parameters
specified on the voltage transformer have to be configured, e.g. 690V / 100V, as well as the measuring mode,
e.g. L12 for the measurement 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.
Possible discharge times are 0, 3, 30, 60, 300, 600, 900 sec. Please make sure that the correct value is set,
otherwise the capacitors could be damaged.
Configuring the capacitor stages:
There are two ways of configuring the capacitor stages: The stages can be configured manually or using the
learning mode.
It is important to set the stage power correctly. The stage power can be looked up on the nameplate of the
stage or the circuit diagram and then programmed manually. In this case, skip the menu item Activate learning
mode and individually enter the power value vor each stage.
If you want to Activate the learning mode, you have to make sure that all previous submenu parameters
have been set correctly.
The learning mode is activated by pressing the button
U
. Change to Yes with the button
V
and confirm with
the button
X
.
After starting the learning mode,
"active"
is flashing, and the remaining time until the end of the learning
mode is displayed.
b
Note!
If the menu item Activate learning mode cannot be selected, you have
to verify that there is measurement voltage available at the controller.
If this is not the case, the menu item is automatically disabled.
b
Note!
The learning mode then automatically sets the stage power. However,
this value has to be checked after each time the learning process is
performed.
