4.6 Disassembly of the 130 for service
To disassemble a 130-01 refer to Figure 52 on page 69 and follow these
steps:
1. Power off the 130-01.
2. Check and make sure the cap (130-9002) is installed on the well disk enclosure
(Item 3).
3. Flip the 130-01 DAS upside-down on the top of the top case (Item 1).
4. Unbolt the bottom base case (Item 15) of the recorder by removal of twelve #8-
32x5/8 screws (Items 16) and the twelve #8 lock nuts (Item 17).
Note: The order of removal is not important until the 130 DAS needs to be
assembled.
5. Remove the bottom half of the case (130-9000) (Item 15).
Note: Make sure the O-ring (Item 14) (130-9004) stays on the bottom half of the
130-01 DAS assembly.
6. If the DAS has a protective EMI shield, remove the cover (form-fitting plastic).
7. If boards need to be removed, loosen and remove the six #6-32 screws (Item
12) or (Item 13) from the stack.
Note: Retain the lock washers (Item 21) with the screws so they do not get
misplaced.
8. Disconnect the CPU ribbon cables (Item 10) and (Item 11) from the CPU board
(Item 9) by spreading the ears on the connections of the CPU board (Item 9).
9. At this point the individual boards may be gently lifted off the stack.
10. The 130-01 DAS configuration can be changed, at this time, by:
ƒ
Adding a memory expansion board to the top of the CPU board (Item 9). Make sure
the board notches match where the cable connectors for the ribbon cables (Item 10)
and (Item 11) are located on the board.
ƒ
Adding a sensor control board (Item 8) after removing the CPU board (Item 9).
ƒ
Upgrade the 130-1/3 to a 130-1/6 6-Channel recorder.
