Description of the display window
Password protection (parameter protection):
A password (a 4-digit numerical code, e.g. 4321) can be used to protect a system against
unauthorized access to the configured parameters.
If the password should get lost, the controller can be unlocked with the master password
1976. To unlock a controller completely, enter the password 9999 (no password = 9999, all
functions are accessible).
Password protection is not active until a waiting time of 300 seconds has elapsed with-
out pressing any buttons.
After unlocking a password protected controller, it is possible to press a button for up
to 300 seconds. If no buttons are pressed during this time, the controller is then locked
again.
The password can be set or changed by pressing
U
to start entering or to change the
entry position,
V
to change or set the password and
X
to save the entry.
Configuring current transformer values:
All current transformer parameters need to be configured correctly for the compensation
controller to function properly. The primary and secondary current of the transformer
need to be set (submenu Iprim. / Isec.). These parameters can be found on the nameplate
of the current transformer. In addition, the phase allocation of the transformer needs to
be configured correctly. This means that the phase (L1, L2, L3) which the current trans-
former is integrated in has to be set (submenu Rot. field I) in the controller. If the trans-
former connections are mixed up (k and l interchanged), this can be corrected with the
setting -L1, -L2 and -L3.
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.
