SEL-311C Relay Instruction Manual Date Code 20060320
Application Settings for SEL-221 Series Relays
SEL-221H to SEL-311C Settings Conversion Guide
Table 14.11 shows all SEL-221H Relay Word bits, and an approximate
equivalent SEL-311C SEL
OGIC expression, when setting APP = 221H in the
SEL-311C. Table 14.10 shows each SEL-221H Mask Logic Setting and the
equivalent SEL-311C SEL
OGIC control equation. To convert an SEL-221H
Mask Logic Setting to a SEL
OGIC control equation, logically OR each
appropriate SEL-221H Relay Word bit equivalent expression (Table 14.11)
and enter the resultant expression in the related SEL
OGIC control equation
listed in Table 14.10.
