Control Equations and
Monitor Logic
Introduction
The SEL-701-1 Monitor is equipped with programmable logic so you can
customize various monitor functions. Use the programmable logic components
described in this appendix to modify the factory default logic settings discussed in
Section 3: Settings Calculation
. This appendix also describes SEL
OGIC®
control
equations and their various applications within the SEL-701-1 Monitor. Specific topics
include:
General Operation of the Monitor.
Relay Word Bits.
SEL
OGIC
Control Equations.
Front-Panel Display Configuration Settings.
Nondedicated SEL
OGIC
Control Equation Variables.
Latching Variables.
Stop/Trip Logic.
Breaker Auxiliary Contact Input.
Start and Emergency Restart Logic.
ACCESS2 Input Logic.
TARR Input Logic.
Speed Switch Contact Input.
Event Triggering.
Output Contact Control.
Remote Control Functions.
and
summarize all the Relay Word
bits. Use the Relay Word bits to create SEL
OGIC
control equation settings. Figures in
this section summarize the operation of many protection elements.
