See Programmable Output Contact Mask Settings in Section 5: Applications
in the SEL-221-16 Instruction Manual for a description of output masks. In
the SEL-311C, output masks are replaced by SEL
OGIC control equations as
shown in Table 14.29.
Table 14.30 shows all SEL-221-16 Relay Word bits, and an approximate
equivalent SEL-311C SEL
OGIC expression, when setting APP = 221-16 in the
SEL-311C. Table 14.29 shows each SEL-221-16 Mask Logic Setting and the
equivalent SEL-311C SEL
OGIC control equation. To convert an SEL-221-16

SEL-311C phase-to-phase fault detector settings (50PP1, 50PP2, and 50PP3) are set to their minimum values and hidden. This
corresponds to SEL-221-16 setting 50P.
SEL-311C phase-to-ground and residual fault detector settings (50L1, 50L2, 50L3, 50GZ1, 50GZ2, and 50GZ3) are set to their minimum
values and hidden. This corresponds to SEL-221-16 setting 50NG.
SEL-221-16 function “Remote End Just Opened” (REJO) is not implemented in the SEL-311C.
b
Curve U1 in the SEL-311C is slightly different from curve 1 in the SEL-221-16. Time dial adjustments may be necessary.
