User Configured Event Name
Range: up to 20 alphanumeric characters
Default: ---
Each available protection FlexLogic operand can be renamed to a user-specified value.
This feature allows users to rename operands to allow for clearer identification or to
match specific applications. The new operand name appears in protection and
automation logic, in settings that take operands as their value, and in event reports.
The following protection FlexLogic operands are available for the D90
alphabetically by operand syntax. The definitions reflect the default operand names. Some
operands can be renamed within their settings window, including the names of breakers,
contact inputs, virtual inputs, and virtual outputs. All operands can also be assigned user-
defined names through the Settings > Configure FlexOperands menu.
