2.4.1 Configurations
In this section, the user can enter the settings of many different parameters concerning the relay
and circuit-breaker, such as the size of the CB, the frequency, the Neutral setting, the
programmable contacts, the communication parameters, etc.
Use the  and  keys within the menu to position the cursor on the required parameter, then
change the values of the parameters within the permitted range using the  and  keys. Once
the changes have been made, press ESC to display the confirmation page.
2.4.1.1 PR223DS: Current Measure Calibration
The current readings in the PR223DS relay can be corrected in the manual mode by means of the
calibration procedure.
The relay only accepts corrections for current values exceeding 0.05In. The maximum deviation
in relation to the value read without calibration is 5%. Calibration can be reset by restoring the
default configuration (the “Restore Default” command in the calibration menu).
2.4.1.2 PR223EF: S51/P1 Contact configuration
The option allowing the status of contact S51/P1 and the external contacts to be configured and
read is available from relay release 3.01 onwards.
2.4.2 Protections
The settings are made by means of the same procedure used for programming the configuration
parameters.
Different protections are available, depending on the model and version of the relay. Consult the
manuals and catalogues of the individual values for a full description.
With PR223EF, the type of interlock for the IL protection (Driver), required for connection to
relays of a different type, is available from release 3.01 onwards. Consult the manual of the unit
for details.
