J1(K1) Fault Phase lg:
Range:
For Ground CT: 0.000 to 46.000 x CT in steps of 0.001 x CT
For Sensitive Ground CT: 0.000 to 4.600 x CT in steps of 0.001 x CT
Default: 0.000 x CT
J1(K1) Fault la(lb,lc,lg) Angle:
Range: -359.9° to 0.0° in steps of 0.1
Default: 0.0°
The Post-fault state is intended to simulate a system that has tripped by replacing the
normal input parameters with programmed post-fault values.
Voltage magnitudes and angles are entered as Wye values only. The voltage setpoints are
not available if the corresponding VT Bank PHASE VT CONNECTION setpoint is Delta.
Voltages are set in secondary VT units.
The CT and VT Bank availability is dependent on the installed Order Code options.

The Test LEDs setting is used to program the state and color of each LED when in test
mode and Force LEDs is "Enabled".
Test LEDs setpoints here (in test mode) will revert to default values at power-up.
Path: Setpoints > Testing > Test LEDs
LED 1 (17)
Range: Off, Red, Green, Orange
Default: Off
Selects the color of each LED when the relay is in test mode (Simulation State is not set
to "Disabled") and Force LEDs is "Enabled". The setpoints Simulation State and Force LEDs
are found under
Setpoints > Testing > Simulation > Setup
