SPS Board LEDs
There is one green LED on each of the SPS boards labeled DS1. If the SPS board
is healthy, the corresponding LED will be illuminated (need 1, 2 or 3 test power
harnesses for 2kV/3...4 kV/6 kV drives, respectively). If any of the SPS board DS1
LEDs do not illuminate, the SPS board is defective. The output voltage should be
within 20 V, ± 2%.
Gating Tests After testing the drive converters without Medium Voltage and verifying the
power supply output values, test the SCRs and SGCTs under low voltage control
power.
The following procedures describe the next level of device testing:
• Gating Test Mode
• SCR Firing Test
• SGCT Firing Test
