Product Description

The General Electric Direct Current Power Supply and Instrumentation Board DS200SDCIG2 serves as an interface to DC2000 drives. There are multiple fuses on the DS200SDCIG2 that help protect the components of the board from current overload, accidental electrical shorts, defective MOV assemblies, and defective SCR packages. A blown fuse might indicate that the  board is defective. One feature to assist with troubleshooting is that each fuse has a LED light that is lit when the fuse is blown. That helps with problem identification.  

However, because the LED are only visible if power is supplied to the board, safety procedures must be followed to view the LEDs. The DS200SDCIG2 is installed behind another board in the drive cabinet so several steps are involved in viewing the LEDs.

First, turn off the drive to initiate a controlled power down of the drive. Remove the fuses from the power supplies to remove all power. Open the cabinet and tilt forward the first board in the cabinet. You now have a clear view of the DS200SDCIG2. Apply current to the drive and perform a restart procedure. Open the cabinet and inspect the board for lit LED lights.

To remove the DS200SDCIG2, first remove all cables. If ribbon cables are connected to the board, grasp the plastic connector on the ribbon cable and the connector on the board and disconnect them by pulling them apart. It is critical to not pull from the ribbon cable to disconnect. The ribbon might break off or be damaged.
