is a summary that compares SEL

control equation programming
in SEL-351 series relays and SEL-311 series relays with typical SEL-400 series
relays.
shows the SEL-400 series Boolean operators compared to the opera-
tors used in the SEL-351 series relays.
In the SEL-351 series relays, SEL
OGIC
control equation variables and timers are
connected. Each SEL
OGIC
control equation variable is the input to a timer. In
SEL-400 series relays, timers and SEL
OGIC
control equation variables are independent.
The SEL
OGIC
control equation Boolean operators in SEL-400 series relays are
different from those used in SEL-300 series relays. For example, if you wish to
convert programming from an SEL-311 or SEL-351 series relay to an SEL-400
series relay, you must convert the operators.
demonstrate conversion of several settings to the SEL-451 setting.
