2. Introductions

This manual is made for using instrument safe and rightly. This manual not respect changing the running mode and safety from external damage to instrument.

This high frequency inverter type of the photo/imaging system is operated by the built-in operation program. It is comfortably designed to satisfy the operator's comfort as well as to enhance the efficiency and the quality of X-ray. Operator can easily select or change the necessary conditions for necessary photographs/images.

(1) This manual is made for operating instrument safe and rightly

(2) This instrument must following this manual process.

(3) Read this manual carefully before using the instrument. Keep this manual closely

for referring later.

(4) EVA HF325/525 is a radioactivity medical instrument and using under the medical

management. So it needs the authorized person who has the know-how about the X-ray.

(5) High voltage generating circuit provides stable X-ray out put with little radiation through rectifying electric wave method.

(6) X-ray tube system is made in rotary bipolar method which uses two foci(small focus

1.0mm/ large focus 2.0mm) to enhance its durability.

(7) Control panel consists of x-ray controller and communication cable. So it can dealt the X-Ray irradiation and control from the long distance. LCD display allows the operator to irradiate at best X-ray irradiating conditions.

(8) Table and stand are connected into one single unit. Therefore, no extra stand rail work is needed. Table moves in four directions to provide easy-positioning.

(9) Temperature sensor is attached to prevent TUBE from overheating. micom-controller senses the temperature and protects the TUBE becoming too hot.

(10) X-ray Controlling device and high voltage radiation device are all built in one unit. Therefore, it is easy to convey and possible to install even in a small space.

(11) PSU(POWER STORAGE UNIT) does not need much power and works efficiently under 2kW~3kW. Therefore, you could reduce electricity rate and save electricity cost. (PSU OPTION)

(8) Wide selecting modes allow the operator to combine and create various working conditions.

Only the legally authorized person(doctor, radio-diagnosis technician, X-ray diagnosis engineer) has the permission to operate the system

4.1 Safety rule

◆ KOMED Co, Ltd designs and builds this instrument complying with

related safety requirement.

Only the authorized personnel can remove the covers and/or have access to the components under tension.

☞WARNING

This device has not been designed to be used in environments where vapours, anaestethic mixes flammable with air, or oxygen and nitrous oxide can be detected.

Avoid pouring water, even accidentally, or other liquids into the device, as this cause short-circuits.

Before cleaning the device, please disconnect it from the line voltage

Wherever necessary, use the accessories, such the leaded aprons, to protect the patient from radiation

While performing the radiography, no one, apart from the operator and the patient, must remain in the room.

EVA-HF 325/525 has been built to support a continuous operation at intermittent

load.

Cooling down the storing heating at a radioactivity origin, must follow the described use cycles.

Operating

☞ WARNING !

Though the X-ray quantity supplied by radioactivity units is quite low and distributed on a small surface, the operator must adopt the precautions and fit protections for the patient and himself, during the execution of radiography. It is advisable to control the X-ray emission from a protected area, by means of a remote control. If it is necessary to operate near the patient, stay as far as the cable of the remote control allows it, or at least 2m far both from the X-ray source and from the patient.

4.2 Electronic safety

◆ Before handling the system, be sure to check the following instructions.

● Make sure the source power voltage and capacity match up to AC220-240VAC(37.5kW/40kW). (When using PSU, DC voltage 370VDC)

● Make sure all the connecting terminals(collimator, high voltage cable, bulky, and etc.) are properly connected.

● Make sure the system's grounding is perfectly done. (If the grounding is imperfect, there may be noise.)

☞ Warning !

Through this unit has been designed with a quite acceptable protection level from electromagnetic interferences, it is advisable to install it a certain distance from electrical energy transformation chambers, from Uninterruptible Power Supply(UPS) units, from portable receiving-transmitting units.

Mobile telephones are only admitted at a distance of more than 1,5 m from any component if the device.

Other medical instruments and devices that must be used in the same installation area of the unit must comply the Electromagnetic Compatibility rules in force.

Non-complying instruments, of which the poor immunity from electromagnetic fields in well known, must be installed at least 3m far from the EVA-HF325/525 and supplied by a different electrical line.

AC input voltage is converted into DC voltage by a single-phase all wave rectifier circuit. This DC voltage is inverted in high-frequency voltage of about 20kHz by IGBT inverter. The high-frequency voltage is converted into the 40 (+20kV/-20kV) to 125kV (+62.5kV/-62.5kV) DC high voltage by a high-voltage transformer and the multi-voltage rectifier circuit. This DC high voltage is supplied to an X-ray tube through a high-voltage cable, and PWM INV controls this X-ray tube voltage. Modulating the Filament voltage controls the tube current.

. The operation panel can operate selection in each mode of operation and control, selection and setting of conditions. These operation conditions are transmitted by the communication system from OP-CONT to HT-CONT. HT-CONT controls the output of a high-voltage generator according to the instructions from OP-CONT.
