currents. Either Block-3P or Block-PerP should be set for the scheme switch [OCSTUB-2fBlk]:

the Block-3P is used when the trip signal should be blocked when the 2f is observed in three-

phase; whereas the Block-PerP is used when the trip signal should be blocked when 2f is

observed in a phase. The user can program a block signal using PLC connection point

"STUBOC_BLOCK".

If an STUB-OC operation test is required in Stub protection area, the user can have a

test by setting [STUB-Test]=On. Consequently, the user can examine the function regardless

of the DS condition in the stub area.
