Protection Flexlogic™ Operands - GE D90 Plus Instruction Manual

PROTECTION FLEXLOGIC™
Protection FlexLogic™ operands
414
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 will appear 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 listed below 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 item.
