SPINDLE DRIVE Instructions for Removal and Installation of the Spindle Drive Circuit Boards 1 . 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. 5 . 9 . Illinois 6M$2 . 10 . Shut off the Control and turn off the Main Power Switch 2 . squezze the tabs together with a pair of needle-nose pliers while gently lifting the board . Remove the screws and gently lift the board free . back to their white connectors and pull *NOTE : These plugs are labeled I and 2 . 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 . The large board is no nnally held down by 9 screws.FOR TYPO YS-626 A. *CAUTION : When handling circuit boards ensure that they are not set on a wet surface . 4 . 3 . To remove the board. All of the Ribbon cables and all of the connectors are keyed to fit only in one direction in their appropriate sockets . Make a list of all the wires onto the terminal strips on both the large and small boards on the spindle drive . lift it gently away . 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 . The small board is held down by plastic squeeze tabs .8 of which are located on the outside edge of the board . When the board is free. To install the new boards simply reverse the above procedure .and set it aside . Ensure that all of the wires on the terminal strip are in their proper location and that they are tightly screwed down . Open the door to the Spindle Drive Cabinet 3 . Remove the clear plastic cover on the Spindle Drive . The remaining screw is located in the very middle of the board . 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 the connectors apart .C . If possible set them on plastic of some sort . 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 .
