Installation of X-ray Tube Housing
When you install the new X-ray Tube Housing you must ensure that tube is mounted without any extra
horizontal play. To do this proceed as follows:
1. Rotate the tube to the left (CCW) 90° so that the tube you will install can rest naturally on the fixed
brass fitting.
2. On the Interface board PL104, plug cable W402
(connector J4).
3. Reconnect the ground cable (6) to the grounding
points.
4. Reconnect the stator cable connector (4).
5. Reconnect the HT connector (5) to the housing.
6. Re-attach the two screws to securing the interface
plate to the new tube head.
CAUTION
Do not touch the molybdenum and rhodium
filters with fingers.
7. Re-attach the two screws securing the filter wheel
to the interface plate.
8. Carefully replace the newly constructed housing.
9. Reattach the pivots (3) on both sides.
•
Re-attach the left pivot so it is flush against the hous-
ing and tighten the three screws to secure it.
•
Re-attach and push down firmly on the right pivot to
ensure a tight fit.
•
CAUTION: Failure to do this can create a gap that
causes the tube to shift laterally during arm rotation.
The resultant X-ray beam shift can show up as inter-
mittent lateral collimator blade cut-off on images.
10. Re-attach the screws (2) to securing the tilt assembly
(5 mm allen wrench).
11. Re-attach the four screws to secure the upper spacer (1)
(4 mm allen wrench).
12. The HT connector must be lightly coated with silicone lubricant to facilitate easy and full insertion. It is
not used for HV insulation, only as a lubricant.
WARNING
You must use the silicone lubricant that is supplied with the new X-ray tube. If you use any
other type of lubricant such as HV grease it will destroy the HT connector.
