Warning

Warning to Interface with X-ray Generator

1. Housing Rupture

Never input over rated power to X-ray tube assembly.

If the input power exceeds tube specification, it causes the over temperature of anode, insert tube

glass shatter and ultimately the following serious problems due to generating over-pressure by oil

vaporization inside housing assembly.

In such a critical condition causing housing rupture by over load, the safety thermal switch can not

protect X-ray tube even if it works.

* Housing sealing parts rupture.

* Human injury including burns due to hot oil escape.

* Fire accident due to flaming anode target.

The X-ray generator should have a protective function which manages input power to be within

tube specification.

Careful handling is required to treat or transport.

3. Ground Terminal

X-ray tube assembly has ground terminal. Ground cable should be connected.

4. High Voltage

All X-ray tubes operate at voltages high enough to kill through electrical shock. Never touch the

high voltage delivered plugs or terminals.

When direct access to such parts is required, the primary circuit should be disabled and high

voltage capacitors / cables discharged.

5. High Voltage Plug

High voltage plug should be cleaned up and free from any physical damages. Silicon compound

application is required for high voltage stability.

6. Rotating Anode

(1) Test rotation of the anode with the large focus filament at the preheat condition. At this time, do

not apply the tube voltage.

(2) When the hand switch "READY" button is pressed, the filament will become brighter and the

anode target will start rotating. The anode for normal speed will reach the predetermined

number of revolution in 0.4 to 1 sec., and it will continue rotation for some time after the stator

drive input is cut off.

The anode for high speed shall be automatically braked to reduced speed and continue

coasting after the drive input to the stator is cut off.

- 11 -E7843X

(3) Ensure that the anode target rotates in the proper direction.

X-ray tube should always rotate counter-clockwise, viewing from the cathode side.

- Confirm direction of rotation -

(4) If the inside of any tube unit cannot be observed (for example, the tube unit with a beryllium

window, etc.), check the tube unit to ensure again that the terminal numbers of the drive circuit

of the low-voltage terminals are properly connected.

7. Operation Atmosphere

X-ray tube assembly is not allowed to be used in the atmosphere of flammable or corrosive gas.

8. Protective Cover

X-ray tube assembly is not allowed to be used without the protective cover attached.

9. Handling

Appropriate jig or tools are required for tube installation to avoid physical damages.

10. Returning Tube

X-ray tube assembly should be repackaged with the original material when it is returned back for

quality examination in our factory. Be careful to put the tube upside cathode. If the packaging is not

proper, the tube may not be correctly examined. CETD does not warrant it if returned X-ray tube

assembly is in damage at receiving.

Caution in Rupture Disc

The Rupture Disc is mounted on anode side housing wall.

When external cover is removed, it is visibly recognized as labeled with label 3 in Caution Labels

page.

Followings are important notice of the Rupture Disc:

Function:

When housing inner pressure reaches to the working pressure of the Rupture Disc, the Rupture

Disc collapses and vaporized oil and hot oil flow through the collapsed Rupture Disc.

The external cover can protect the initial impact of oil flow, however, it can not protect oil drop or oil

leakage.

Caution:

1. 2. Never touch the Rupture Disc or remove the label and the screws.

Otherwise, it could cause collapse of Rupture Disc.

Please note the Rupture Disc is not the device to protect X-ray tube from destruction when over

rated power input but just to reduce the impact of housing rupture.
