REX640 Engineering Manual

The protection relay contains a default configuration when delivered. The default configuration contains a simple application configuration and an LHMI configuration which can be used as a basis when the actual application configuration is created for the protection relay installation. The default configuration does not have output relays connected in the application configuration, so the relay and its configuration must not be used in installation as they are; modification of the application configuration is always required before commissioning.

The default configuration is available for IEC 61850 Edition 2 only, though the relay supports the IEC 61850 Edition 1 as well. For instructions on how to enable Edition 1 for the relay, see chapter IED insertion.
