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 work 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.  2.Electric Shock To avoid the risk of electric shock ,this equipment must only be connected to a supply with protective earth.  3.No modification of this equipment is allowed!!

Warning

Cautions

Caution to interface with X-ray Generator 1.Over Rating X-ray tube assembly can be broken with applying just one over rated shot. Please read the technical date sheets carefully and follow the instructions. 2.Permanent Filtration The total filtration and the distance between X-ray focal spot and human body are regulated legally. They should be complied with the regulation. 3.Safety Thermal Switch X-ray tube assembly has safety thermal switch to prohibit further input power when the tube housing reaches to the temperature80 of switch-open. The switch is not recommended connecting stator coil in series circuit. Even if the switch works ,never turn the system power off. The cooling unit should be activated if used with the system. 4.Unexpected Malfunction X-ray tube assembly may have the risk to be unexpectedly malfunctioning due to life termination or failure.If the serious problems caused by the above risk is expected,you are requested to have a contingency plan to avoid such a case. 5.New Application If you use the product with new application not to be mentioned in this specification or with different type of X-ray generator,please contact to us for confirming its availability.

Caution in Operation

1 .X-ray Radiation protection

This product fulfills the requirements of IEC 60601-1-3. This X-ray tube assembly emits X-ray radiation in operation.Only correspondingly qualified and trained personnel are therefore allowed to operate the X-ray tube assembly. Relevant physiologic effects may cause harm to patient,system manufacture should take proper protection to avoid ionization radiation. 2.Dielectric 0il X-ray tube assembly has dielectric 0il contained for high voltage stability. As it is poisonous for human healthif it is exposed to the non-restricted areait should be disposed as following to the local regulation. 3 .Operation Atmosphere X-ray tube assembly is not allowed to be used in the atmosphere of flammable or corrosive gas· 4Adjust the Tube Current Depending on the operating conditionsthe filament characteristics might be changed. This change might Iead to the over rate exposure to X-ray tube assembly. To prevent the X-ray tube assembly from being damagedadjust the tube current  regularly. Besides when the X-ray tube has arcing Problem in a long time useadjustment of the tube current is required. 5.X-ray Tube Housing Temperature Do not touch on X- ray tube housing surface just after operation due to high temperature. Stay X-ray tube to be cooled. 6 .Operating limits Prior to usageplease confirm the environmental condition is within the operating Iimits. 7 .Any Malfunction P1ease contact to SAILRAY immediatelyif any malfunction of the X-ray tube assembly is noticed. 8.Disposal The X-ray tube assembly as well as the tube contain materials such as oil and heavy metals for which environmentally friendly and proper disposal in accordance with the valid national legal regulations must be assured.Disposal as domestic or industrial refuse is forbidden.The manufacturer possesses the required technical knowledge and will takes the X-ray tube assembly back for disposal. Please contact customer service for this purpose.
