Table 9-10: Emergency Voltage Unbalance
This test will change the output voltage for phase A and B to 122V and phase C to a voltage lower by a
value specified by an offset. Refer to Table 9-10 for the offset value and the Frequency. The test will
repeat with the same frequency and phase A and B volt is set to 100V and phase C set to a higher
voltage specified by the offset. The test will last 30 minutes. The test will be repeated for a second
Frequency if applicable. The test can be terminated at any time.
The BACK key (backspace) will terminate the test at any time.
