5.1

Overview

The customer specific values for each setting parameter and a configuration file have to be available
before the IED can be set and configured, if the IED is not delivered with a configuration.
Use the configuration tools in PCM600 to verify that the IED has the expected configuration.
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.The
Parameter Setting Tool in PCM600 is used when changing setting parameters.
All settings can be
• Entered manually through the local HMI.
• Written from a PC, either locally or remotely using PCM600. Front or rear port communication
has to be established before the settings can be written to the IED.
The IED uses a FLASH disk for storing configuration data and process data like counters, object
states, Local/Remote switch position etc. Since FLASH memory is used, measures have been taken
in software to make sure that the FLASH disk is not worn out by too intensive storing of data.
This means, that to be absolutely sure that all data have been saved to FLASH, it is necessary to
leave the IED with auxiliary power connected after all the commissioning is done(including setting the
Local/Remote switch to the desired position) for at least one hour after the last commissioning action
performed on the IED.
After that time has elapsed, it will be safe to turn the IED off, no data will be lost.

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 PCM600.
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.
The primary CT data are entered via the HMI menu under Main menu /Configurations /Analog
modules
The following parameter shall be set for every current transformer connected to the IED:

Make sure that the DC supply is not turned off when the IED saves the written
configuration.
