Procedure 14. W3 Line Switch Cable
Replacement (Using Contact Removal Tool, HP part number 8710-1791)
1. Ensure that the action of the switch is working properly. With a pair of wire cutters, clip
the tie wrap holding the cable to the contact housing of the replacement W3 assembly.
2. Using the contact removal tool, remove the four wires from the replacement cable
assembly’s connector.
3. From the bottom side of the analyzer, insert the contact end of W3 through the slotted
opening in the main deck. W3 should come through to the top side of the analyzer
between the Al8 CRT assembly and the post-accelerator cable.
4. Place LED AlWlDSl into the line-switch assembly.
5. Attach the line-switch assembly into the front frame, using the captive panhead screw. Be
sure to connect the line-switch grounding lug with the screw.
6. Dress W3 between the main deck standoff and the side frame. See Figure 3-24.
7. On the top side of the analyzer, redress W3.
8. Insert the four contacts into the W3 connector.
9. Attach the cable to the connector housing using the supplied tie wrap.
10. Connect W3 to
A6J2. Dress W3 into the slotted opening in the deck.
11. Connect AlAlWl to A3J602.
12. Secure the power-supply cover shield to the power supply, using three flathead screws.
One end of the cover fits into a slot provided in the rear-frame assembly.
13. Redress W3 and the other cable assemblies down between the CRT assembly and the
power supply cover such that the
W9 wires are below the surface of the power-supply
cover.
14. Fold up the A2, A3, A4, and A5 assemblies into the analyzer as described in Procedure 5,
“A2, A3, A4, and A5 Assemblies Replacement,” steps 5 through 10.
15. Fold up Al4 and Al5 assemblies as described in Procedure 9, “Al4 and Al5 Assemblies
Replacement,” steps 9 through 11.
