Chapter 5 Troubleshooting
SCR Troubleshooting
Non-regenerative drives contain three SCR packs, A, B, and C. Each SCR pack contains two thyristors. Three
additional SCR packs (D, E, and F) mount above SCR packs A, B and C for regenerative drives. The layout of the
SCR packs is shown in Figure 5.17 as they appear on the drive heatsink, from left to right.
Use the tables in Figure 5.18 to determine which SCR pack is bad. The tables show the SCR being tested and the SCR
pack that contains it. Measure the resistance between each armature and supply terminal. A good SCR will measure
greater than one M
W
when read from the armature to the supply terminal. Reverse the leads and repeat these measure-
ments between the supply and armature terminals. Bad (shorted) SCRs should measure zero to one k
W
.
Remove the power supply board (see Chapter 7) and measure the resistance between the gate and the cathode. It
should measure between 18 and 40
W
if good. A schematic of the SCR pack appears in the right of Figure 5.17. The
outer most terminals connected to yellow leads at the bottom of each SCR pack are the thyristor gate terminations.
