Section 3 REF611 standardized configurations
3.1 Standardized configurations
REF611 is available in three alternative configurations.
To increase the user-friendliness of the configurations and to emphasize the relay's
simplicity of usage, only the application-specific parameters need setting within the
relay's intended area of application.
The standard signal configuration can be altered by local HMI, Web HMI or optional
application functionality of Protection and Control IED Manager PCM600.
