Replacement of board D200
To replace the board D200 in the biopsy controller, proceed as follows:
1.
Remove the screws (3/Fig. 5) holding the connectors X201, X202, X206, X207,
X208.
2.
Loosen the four screws (1/Fig. 5) on the back side of the biopsy controller.
3.
Loosen the four screws (7/Fig. 5) on the side of the biopsy controller.
4.
Remove the screws (6/Fig. 5) holding the board.
5.
Remove the board and install the new board. If necessary, loosen the transformer.
Make sure to replace the isolation film at the connectors X203, X204 and X205.
When installing the board, pry the board holders carefully in position by using a
screwdriver at the slots (5/Fig. 5) on the back side of the biopsy controller.
6.
With an ohm meter verify that the isolation film at connectors X203, X204 and
X205 is functioning properly. The resistance shall be in excess of 10 Mc, when
measuring between the back side of the biopsy controller and the shielded
housing surrounding the pins of the connectors X203, X204 and X205. If the
resistance is less than 10 Mc, the isolation film has to be replaced.
