Password protection:

To protect a system against unauthorized access of the con gured parameters,

a password can be entered (4-digit number code, e.g. 4321).

In case the password gets lost somehow, the controller can be unlocked with

the master password 1976.

When unlocking a password protected controller, it is possible to press a button

within 300 seconds. If no button is pressed during this period, the controller is

locked again.

The password can be con gured by pressing

to start entering and chang-

ing the entry position,

 to change or set the value and  to save the entry.

Con guring current transformer values:

For the compensation controller to function properly, all current transformer

parameters a ecting the current transformer have to be set correctly. Primary

and secondary current of the transformer have to be set (submenu Iprim. /

Isec.). These parameters can be read on the nameplate of the current trans-

former. In addition, the phase allocation of the transformer has to be set cor-

rectly. In the controller, the phase (L1, L2, L3) in which the current transformer

is integrated has to be set (submenu Rot. eld I). If the transformer connections

are mixed up (k and l interchanged), this can be corrected with the setting -L1,

-L2 and -L3.

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

primary, 400V secondary). With measuring voltages of over 500V, the param-

eters 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 con-

nection between the phases L1 and L2.
