# – any virtual input number
Flag is set, logic = 1
Flag is set, logic = 0
The Volts per Hertz element 1 has picked up
The Volts per Hertz element 1 has operated
The Volts per Hertz element 2 has picked up
The Volts per Hertz element 2 has operated
VT fuse failure detector 1 has operated

of nominal)
If Phase to Phase mode is selected in this protection element, in "EVENT DESCRIPTION"
column, "Phase A" becomes "Voltage AB", "Phase B" becomes "Voltage BC" and "Phase C"
becomes "Voltage CA".
Some operands can be re-named by the user. These are the names of the breakers in the
breaker control feature, the ID (identification) of contact inputs, the ID of virtual inputs, and
the ID of virtual outputs. If the user changes the default name or ID of any of these
operands, the assigned name will appear in the relay list of operands. The default names
are shown in the FlexLogic Operands table above.
