The four possible programs may be set in address 36 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 36 2S PRGH = $OO ]RQHV EORFN for the power swing
blocking, to avoid premature tripping by the distance protection.
