SELOGIC Variables Equations
SV1 = 25A1
SV2 = 59VP * !59VS * !50L * LT1 + 59VS * !59VP * !50L * LT2
SV3 = M3P + Z3G
SV4 = 0
SELOGIC Latch Equations
The SELOGIC latch equations emulate the SEL-221F setting PSVC for
settings P, S, and E.
The following contact input assignments are made automatically by the
SEL-311C when setting APP = 221F. These assignments cannot be changed
unless setting APP is changed back to APP = 311C.
Default Contact Input Functions
IN101 = Programmable Input (Direct Trip)
IN102 = PT (Permit trip)
IN103 = BT (Block trip)
IN104 = CL (Close breaker)
IN105 = 52A
IN106 = EXT (External event report trigger)
