SPINDLE DRIVE Instructions for Removal and Installation of the Spindle Drive Circuit Boards 1 . Shut off the Control and turn off Main the Power Switch 2 . Open the door to the Spindle Drive Cabinet 3 . Remove the clear plastic cover on Spindle the 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 complete and correct before removing any wi res 6 . 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 wires (the wires are wound together as a twisted pair) Trace these back to their white connectors and pull the connectors apart . *NOTE : These plugs are labeled and I 2 . 3 . The small board is held down by plastic squeeze tabs . To remove the board, squezze the tabs together with a pair of needle-nose 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 set on a not wet surface . If possible set them on plastic of some sort . 9 . The large board is nonnally 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 fit only to in one direction in their appropriate sockets . Ensure that all of the wires on are the terminal strip 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) 564-0806 Please return the bad boards to : YASNAC America Inc .
