REG615 standard configurations
3.1
Standard configurations
REG615 is available with three alternative standard configurations. The standard
signal configuration can be altered by means of the signal matrix or the graphical
application functionality of the Protection and Control IED Manager PCM600.
Further, the application configuration functionality of PCM600 supports the creation
of multi-layer logic functions using various logical elements, including timers and
flip-flops. By combining protection functions with logic function blocks, the relay
configuration can be adapted to user-specific application requirements.
The protection relay is delivered from the factory with default connections described
in the functional diagrams for binary inputs, binary outputs, function-to-function
connections and alarm LEDs. Some of the supported functions in REG615 must be
added with the Application Configuration tool to be available in the Signal Matrix tool
and in the relay. The positive measuring direction of directional protection functions
is towards the busbar.
