ABB CTB811 HN800/CW800 Troubleshooting Information Card

Description

Single PBA

To install the PBA cables for a nonredundant configuration

(one PBA):

1. Install the redundant processor bus adapter cable.

NOTE: Refer to Section 8 and Appendix B to determine the type and length of

the cable.

2. Position the end socket connector on the PBA bracket so

that the pins of the cable are facing outward.

3. Install a terminator to the end socket connector on the

redundant processor bus adapter cable.

NOTE: The end socket connector is keyed, but the terminator is not. The termi

nator can be installed in any direction.

4. Insert the next keyed connector on the redundant proces

sor bus adapter cable into the P1 connector on the PBA with

the terminator mounted to it.

5. The next keyed connector on the cable is used only for

redundant installations and has no purpose in single PBA

installations. It can be left hanging.

6. Attach the final cable connector to the I/O column after

the PBAs have been mounted. Continue to Mounting in this

section to mount the PBA.

NOTE: The TU cable for the direct station link can be installed at any time after

the PBA is installed. Refer to Appendix B for more information.

Before installing a controller:

1. Check all controller dipswitch and jumper settings (normal

and special operation).

2. Verify that the PBA if required, is attached to the proper

slot on the MMU backplane.

NOTE: Controllers can be installed and removed under power. When doing so,

the status LED will turn red momentarily and then turn green. If it does not,

refer to Section 5 for troubleshooting information.

To install a controller:

1. Slide the controller into its mounting slot while guiding the

top and bottom edges of the controller along the top and bot

tom rails of its assigned slot in the MMU.
