Shut off the Control and turn off the Main Power Switch2. Open the door to the Spindle Drive Cabinet3. Remove the clear plastic cover on the Spindle Drive.4. Make a list of all the wires onto the terminal strips on both the large and small boards on the spindle drive. These strips are located on the left side of both boards and also there are some small terminals on the bottom of the small board.5. Remove all wires from the board to be replaced★CAUTION: Insure that your wire list is plete and correct before removing any wi res6. Remove all ribbon connectors and if necessary remove the connector with the yellow wires at the top of the large board (it has 5 straight pins in a row)7. If the large board is to be removed: At the top of the board there are 2 pairs of Red and White wi res (the wires are wound together as a twisted pair) Trace these back to their white connectors and pul 1 the connectors apart.★NOTE: These plugs are labeled 1 and 2.3. The small board is held down by plastic squeeze tabs. To remove the board, squezze the tabs together with a pair of needlenose pliers while gently lifting the board. When the board is free, lift it gently away and set it aside.★CAUTION: When handling circuit boards ensure that they are not set on a wet surface. If possible set them on plastic of some sort.9. The large board is normally held down by 9 screws,8 of which are located on the outside edge of the board. The remaining screw is located in the very middle of the board. Remove the screws and gently lift the board free.10. To install the new boards simply reverse the above procedure. All of the Ribbon cables and all of the connectors are keyed to fit only in one direction in their appropriate sockets. Ensure that al1 of the wires on the terminal strip are in their proper location and that they are tightly screwed down.If you have any questions or problems please call: YASNAC Service Department Phone Number (312) 5640806Please return the bad boards to:YASNAC America Inc.Attn: Field Service Oepartzsent 305 Era DriveNorthbrook, Illinois 60^2q.
