Section 3 REU615 standard configurations

3.1 Standard configurations

REU615 is available in two standard configurations. The standard signalconfiguration can be altered by means of the signal matrix or the graphicalapplication functionality of the Protection and Control IED Manager PCM600.Further, the application configuration functionality of PCM600 supports thecreation of multi-layer logic functions using various logical elements, includingtimers and flip-flops. By combining protection functions with logic functionblocks, the IED configuration can be adapted to user-specific applicationrequirements.

The IED is delivered from the factory with default connections described in thefunctional diagrams for binary inputs, binary outputs, function-to-functionconnections and alarm LEDs. The positive measuring direction of directionalprotection functions is towards the outgoing feeder.

3.1.1 Addition of control functions for primary devices and theuse of binary inputs and outputsIf extra control functions intended for controllable primary devices are added to theconfiguration, additional binary inputs and/or outputs are needed to complementthe standard configuration.

If the number of inputs and/or outputs in a standard configuration is not sufficient,it is possible either to modify the chosen IED standard configuration in order torelease some binary inputs or binary outputs which have originally been configuredfor other purposes, or to integrate an external input/output module, for exampleRIO600, to the IED.

The external I/O module’s binary inputs and outputs can be used for the less time-critical binary signals of the application. The integration enables releasing someinitially reserved binary inputs and outputs of the IED’s standard configuration.

30 REU615Application Manual

The suitability of the IED’s binary outputs which have been selected for primarydevice control should be carefully verified, for example make and carry andbreaking capacity. If the requirements for the primary device control circuit are notmet, using external auxiliary relays should be considered.
