PCD CPU Module Replacement Procedure
Follow these instructions to replace the PCD CPU Type 2 modules.
CPU Type 2 Part Number: 616016-T2
Precautions
The following precautions should be taken when replacing or servicing any of the PCD modules:
1. Use antistatic precautions when handling modules. Always use antistatic bags for transporting modules
2. Remove AC power
and
DC power from the PCD before removing, installing or wiring any of the PCD
modules.
3. Incorrect wiring may result in damage. Before energizing the PCD verify that the connectors are
plugged into the correct locations and the wiring agrees with the connection diagram.
4. Apply only the rated AC control voltage.
Instructions
The following instructions contain information required to correctly replace the PCD CPU Type 2 module,
located in Slot D.
1. Remove AC and DC system power from the PCD, following your company safety guidelines
2. Locate the module labeled “CPU Type 2”, which is mounted Fourth from the left side when
facing the rear of the PCD in Slot D , see figures 1 & 2.
3. Locate the mounting screw in the top center of the CPU Type 2 module. Remove the screw
and set aside.
4. Locate the mounting screw in the bottom center of the CPU Type 2 module. Remove the screw and set
aside.
5. Carefully remove the CPU Type 2 module from the relay housing and set aside.
6. Carefully remove the replacement CPU Type 2 module from the packaging and insert into
the PCD chassis. Be certain to align the printed circuit board with the card guides in the
housing.
7. Insert the mounting screws that were previously set aside and tighten.
8. Reconnect DC then AC power and the PCD should power up normally.
9. Once the new module is installed, you may get the following prompt on the LCD: “Modules
have changed, Press key to update”. If so, do the following:
a)
Press the ENTER key. Prompt will appear: “Update Catalog number?”
b)
Press the right arrow key to select “Yes” then press ENTER

Prompt will appear: “Confirm Update?” Press the right arrow key to select “Yes”.
f)
A password prompt will appear. Press ENTER to proceed, as the default password is 4 spaces.
g)
After the modules have been updated, reset the PCD by pressing the reset button on the rear of the
CPU module. The Self Check LED at the right hand side center of the faceplate should now be
GREEN. If it is RED call ABB for assistance.
h)
All settings on the PCD are stored in the CPU card. Therefore, after installing the new CPU card,
the desired protection setting will need to be reprogrammed into the unit.
