RS Series 172
Voltage 1 122 122 122 122
3 120.5 120.5 120.5 120.5
Frequency 420 410 650 800
Table 9-2: Normal Voltage and Frequency Maximum
This test will set the voltage and frequency to levels defined by Table 9-1. The test will last for 30
minutes. The test will be repeated for the Group 2 and 3 using the Voltage setting from Table 9-2
and the frequency from Table 9-1. The ← key (backspace) will terminate the test at any time.
VOLT FREQ MAX
This test will set the voltage and frequency to levels defined by Table 9-2. The test will last for 30
minutes. The test will be repeated for the EURO standard using the Voltage setting from
Table 9-1 and the frequency from Table 9-2. The CLR Key in local operation will terminate the test
at any time. Group execute trigger will terminate the test remotely. The unselected phases will
remain at 115 volts. The ← key (backspace) will terminate the test at any time.
VOLT UNBALANCE
Standard/Group RTCA Group1 Group2 Group3
Voltage offset 6 6 6 9
Frequency 400 400 360/650 360/800
Table 9-3: Normal Voltage Unbalance
This test will change the output voltage for each phase from 115 volts to 115V + offset. Refer to
Table 9-3 for the offset value and the Frequency. 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 ← key will terminate the test at any time.
WAVEFORM DISTORTION
This test will generate a 5% THD voltage distortion on the output voltage waveform. The
distortion is generated by using a clipped sine wave. The test will last for 30 minutes. The ←
key (backspace) will terminate the test at any time.
VOLTAGE MODULATION
This test requires a numeric value entry equal to the modulation rate in Hz. This entry value
must be between 1 Hz and 200 Hz. The amplitude modulation is calculated based on the
modulation rate as defined in Figure 9-4. This test will last for 2 minutes.
