5 SETTING CHECKS
The setting checks ensure that all of the application-specific relay settings (i.e. both the
relay’s function and programmable scheme logic settings) for the particular installation have
been correctly applied to the relay.
If the application-specific settings are not available, ignore sections 5.1 and 5.2.
5.1 Apply Application-Specific Settings
There are two methods of applying the settings:
• Transferring them from a pre-prepared setting file to the relay using a portable PC
running the appropriate MiCOM S1 Agile software using the relay’s front RS232 port,
located under the bottom access cover, or rear communications port (with a KITZ
protocol converter connected). This method is preferred for transferring function
settings as it is much faster and there is less margin for error. If programmable
scheme logic other than the default settings with which the relay is supplied are to be
used then this is the only way of changing the settings.
If a setting file has been created for the particular application and provided on a diskette, this
will further reduce the commissioning time and should always be the case where
programmable scheme logic changes are to be applied to the relay.
• Enter them manually using the relay’s operator interface. This method is not suitable
for changing the programmable scheme logic.
5.2 Check Application-Specific Settings
The settings applied should be carefully checked against the required application-specific
settings to ensure they have been entered correctly. However, this is not considered
essential if a customer-prepared setting file has been transferred to the relay using a
portable PC.
There are two methods of checking the settings:
• Extract the settings from the relay using a portable PC running the appropriate
software via the front RS232 port, located under the bottom access cover, or rear
communications port (with a KITZ protocol converter connected). Compare the
settings transferred from the relay with the original written application-specific setting
record. (For cases where the customer has only provided a printed copy of the
required settings but a portable PC is available).
• Step through the settings using the relay’s operator interface and compare them with
the original application-specific setting record.
Unless previously agreed, the application-specific programmable scheme logic will not be
checked as part of the commissioning tests.
Due to the versatility and possible complexity of the programmable scheme logic, it is
beyond the scope of these commissioning instructions to detail suitable test procedures.
Consequently, when programmable scheme logic tests must be performed, the Engineer
who created the application-specific scheme logic should devise written tests that will
satisfactorily demonstrate its correct operation. These should be provided to the
Commissioning Engineer together with the diskette containing the programmable scheme
logic settings file.
