The four possible programs may be set in address 362SPRGH, as described
in Sub-section 6.3.1: $OO]RQHVEORFN or ==%EORFNor =WR=EORFN
or ==%=EORFN.
Additionally the tripping function for unstable oscillations (out-of-step condition, loss of
system synchronism) can be set with parameter 3RZHU6ZLQJWULS (address ),
which should be set to <HV if required (presetting is 1R). In the event of power swing
tripping it is sensible to set 362SPRGH = $OO]RQHVEORFNfor the power swing
blocking, to avoid premature tripping by the distance protection.
