Use the configuration tools in PCM600 to verify that the IED has the expected
configuration. A new configuration is done with the application configuration tool.
The binary outputs can be selected from a signal list where the signals are grouped
under their function names. It is also possible to specify a user-defined name for
each input and output signal.
Each function included in the IED has several setting parameters, which have to be
set in order to make the IED behave as intended. A factory default value is
provided for each parameter. A setting file can be prepared using the Parameter
Setting tool, which is available in PCM600.
All settings can be
• Entered manually through the local HMI.
• Written from a PC, either locally or remotely using SMS/SCS. Front or rear
port communication has to be established before the settings can be written.

Entering settings through the local HMI

Procedure
1. Set each function included in the IED in the local HMI.
2. Browse to the function to be set and enter the appropriate value.
3. Find the parameters for each function in the local HMI
The operator's manual is structured in a similar way to the local HMI and provides
a detailed guide to the use of the local HMI including paths in the menu structure
and brief explanations of most settings and measurements. See the technical
reference manual for a complete list of setting parameters for each function. Some
of the included functions may not be used. In this case the user can set the
parameter Operation = Off to disable the function.

Configuring analog CT inputs

The analog input channels must be configured to get correct measurement results
as well as correct protection functionality. Because all protection algorithms in the
IED utilize the primary system quantities, it is extremely important to make sure
that connected current transformer settings are done properly. These data are
calculated by the system engineer and normally set by the commissioner from the
local HMI or from the SMS.
The analog inputs on the transformer input module are dimensioned for either 1A
or 5A. Each transformer input module has a unique combination of current and
voltage inputs. Make sure the input current rating is correct and that it matches the
order documentation.
