Factory Default Logic Settings
When you use the factory default logic by setting FACTLOG equal to Y, the relay
hides the logic settings and default settings shown below. Operation of these default
settings is described in Section 4: Settings Calculation.
If you set FACTLOG equal to N, the relay displays each of the settings in the
screen capture below. You can modify one or more of these settings to customize the
relay function. Descriptions of the functions controlled by the default settings are
included in the remainder of this appendix.
NOTE: If you change SELOGIC control equation settings, then
return the FACTLOG setting to Y, the relay will clear your
changes and resume using the factory settings shown below.
