Functional diagrams for protection

The functional diagrams describe the relay protection functionality in detail and
according to the factory set default connections.
Four overcurrent stages are offered for overcurrent and short-circuit protection. Three
of them include directional functionality DPHxPDOC. Three-phase non-directional
overcurrent protection, instantaneous stage, PHIPTOC1 can be blocked by activation
of inrush protection.

The output BLK2H of three-phase inrush detector INRPHAR1 enables either blocking
the function or multiplying the active settings for any of the available overcurrent or
earth-fault function blocks. In the configuration, INRPHAR1 blocks the non-
directional instantaneous stage.
