Customer Interface Board Replacement
The DCB-L, DCB-M, and CIB are all connected together using solid plug
connections. This means that the best way to change any of the boards
without physically stressing the connections and boards is to remove all 3
from the drive and change the board externally.
Instructions to replace the Customer Interface Board
1. Record all drive setup information using any of the options above, if
possible.
2. Ensure that all medium voltage and control voltage power to the drive
is isolated and locked out.
3. Loosen the two metal tabs on the top and bottom right of the panel on
which the SCB-L and SCB-M are mounted. The panel is hinged on
the right side, and should swing open to allow access to the DCB-L,
DCB-M and CIB boards. There is no need to remove any connections
from the SCB.
4. Note and mark the location and orientation of all the ribbon cables,
plugs and connectors into the DCB-L, DCB-M and CIB. Use the
electrical drawing as a reference.
5. Using your static strap, disconnect the fiber optic cables from the
sheet metal by cutting the tie-wraps. The purpose is to create enough
slack to allow the FOI Boards to be moved slightly out of the way,
allowing access to remove the boards. Use great care when handling
Fiber Optics, as any damage can affect transmission capabilities.
6. Remove the Fiber Optic Interface (FOI) Boards from the DCBs.
There are standoffs and pins from the DCB that slide into the FOI
boards, but they are physically attached only using the standoff
connectors, and you have to be firm, but CAREFUL, in freeing the
FOI boards.
7. There are numerous plastic clips holding all 3 boards to the plate.
Loosen the connectors and remove all 3 boards as one unit. If you
need to place the boards on a surface, ensure you have a static pad to
protect the boards.
8. Separate the boards and replace the damaged CIB with the new part.
Verify the part number is the same, and note the revision letters.
9. Follow Steps 7-3 in reverse to re-install the boards back into the low
voltage control cabinet.
