Chamber Troubleshooting

To enable the automatic fuse

If the chamber's automatic fuse is triggered due to overload, proceed as follows:

1. Open the chamber door as described in 

Chapter 7.3.3, "Opening the Door"

,

on page 46.

2. Make sure that no movable parts inside the chamber are blocked mechanically.

For example, if something is blocking the antenna elevation positioner, operating
its motor can draw an excess amount of current.

3. If you find that movable parts are blocked, remove the cause of blocking.

4. On the lower rear side of the chamber, remove the four Torx

 

10 screws securing

the acrylic glass window.

5. Remove the acrylic glass window.

6. Switch the fuse's lever to the left to enable the fuse.

Figure 9-1: Power supply module at feedthrough [A221] (photo on the right: switch lever of the

automatic fuse highlighted in red)

Lever switched to the left = Fuse enabled
Lever switched to the right = Fuse triggered

7. Close the chamber door.

8. Operate the chamber in the same way as you did when the fuse triggered.

9. If the fuse triggers again, contact Rohde
