UGroup X Setting
Some voltage groups support special genset
configurations. See Table 12 above.
UOver Volt Warn X
Over voltage warning setpoint in VAC L-L for
voltage group X.
UOver Volt Warn X
Over Voltage Failure Setpoint in VAC L-L for
voltage group X.
UUnderVoltWarnX
Under Voltage Warning in VAC L-L for
voltage group X.
UUnderVoltFailX
Under Voltage Failure in VAC L-L for voltage
for group X.
Note: Warnings/failures for voltage
group 2 (2 wire option enabled) are in
units of VAC L-N (even though the units
displayed in the menu are L-L).

Voltage Group 3 with the Group 3 Setting set to “Two Times Voltage” is also
useful in 4 wire Wye and 3-wire Delta applications where the user wishes to
measure a voltage greater than 600VAC – the maximum voltage the GSC400
supports. In this case the user can use a 2:1 potential transformer (PT) to step
down the voltage to the GSC400 and still have the GSC400 display the correct
voltage.
