SERVICE MANUAL

Safety information


2.12.12.12.1 WarningsWarningsWarningsWarnings

The system has not been designed to be used in presence of vapours, anaesthetic mixtures that are flammable with air, or oxigen or nitrous oxide. Ensure that water or other liquids do not get into the machine so as to prevent short-circuits and corrosion. Always disconnect from mains before cleaning the machine. Where necessary, accessories such as lead-sealed aprons must be used to protect the patient from radiations. Only the patient and the operator may remain in the room during the execution of the radiography examination. I-MAX EASY has been developed for continuous use with intermittent load. The prescribed operating cycles to allow the heat accumulated by the radiogenic source to be discharged must be observed. Although the appliance has been designed to have a reasonable degree of protection from electromagnetic interference, it must be installed at a certain distance from electricity transformer rooms, static continuity unit, portable two-way hand radios and cellular phones. The latter may only be used at a distance of over 1.5 meters from all elements of the machine. All instruments or equipment for professional use and used near the machine must be in conformance to the electromagnetic compatibility standards. Nonconforming instruments whose low immunity to electromagnetic fields is known must be installed at least 3 meters away from the I-MAX EASY and be powered via an independent electric line. I-MAX EASY must be switched off during the entire period of use of ESU (Electro Surgery Units) units or similar equipment. Clean or eventually disinfect the chin support, positioning handles, temples clamp support, nose rest and any other part that may come in touch with the patient. At the end of the examination, replace the bite and the ear rods.

SERVICE MANUAL

Safety information


Although the X-ray dosage supplied by dental radiology appliances is on average low and distributed over a relatively small surface, the operator must take the necessary precautions and/or follow the safety procedures for both himself and the patient during an exposure. We recommend that the X-ray activation always be commanded from an X-ray protected area via remote control. If it is necessary to operate the exposure near the patient, remain at the maximum distance allowed by the remote control cable in the direction opposite to the emission of the X-rays, at a distance of at least 6.6 feet (2 meters) from both the radiation source and patient.

2.22.22.22.2 Environmental risk and disposalEnvironmental risk and disposalEnvironmental risk and disposalEnvironmental risk and disposal

A number of machine parts contain materials and liquids that upon completion of the machine’s life cycle must be disposed of at recovery centers established by the local health units. The machine contains the following materials and/or components:

• Tubehead: dielectric oil, lead, copper, iron, aluminum, glass, tungsten, beryllium

• Control box and remote control: iron, copper, glass resin, non-biodegradable plastic casings

• Column, rotating arm, extensions: iron, lead, aluminum, copper, non-biodegradable plastic materials, glass resin.

WARNING: Before disassembling the parts, lock the counterweight of the slider inserted in the column. This is possible only after having slid the slider all the way down and inserted a pin approximately 25cm in length and 8mm in diameter. Once the pin has been inserted, move the slider towards the top until the counterweight rests on the pin. Remove the tubehead and some of the parts of the rotating arm. Holding the slider firmly, remove the pin and move the slider towards the top to the metallic stop of the column. At this point, remove all the remaining parts.

Description


3.23.23.23.2 DescrDescrDescrDescriptioniptioniptioniption

I-MAX EASY has been designed to perform the following examinations:

• Panoramic examination

• "SINUS" examination of the paranasal sinus

• Examination of the Temporo-Mandibular Joints (TMJ) with open or closed mouth on a single image

All the allowed examination may be made with different parameters according to the setting of the remote-control (please refer to chapter 6 of User’s Manual).

I-MAX EASY is controlled by a soft touch console and equipped with an alphanumeric digital display for a clear indication of the working parameters and operative messages. The operative cycle is entirely run by a microprocessor, controlling its different modes : from programming of the emission parameters according to the chosen examination and the patient's size, to the voltage fluctuation and to the notification of possible anomalies, failures or errors.

The excellent quality radiographs thus obtained is the result of a clever design based upon the pseudo-elliptic rotation system, the original light beam-luminous cross pattern centering system, the use of green emitting Rare Earth Intensifying screens and most of all the small dimension of the focal spot. This particular rotation system allows an orthogonal imaging of all teeth and wide image layer with an optimum focused zone of 10 mm for the incisors and 20 mm for the molars.

I-MAX EASY, besides operating in the programmed mode, can also operate in the manual personalized mode by modification of the parameters, as described in chapter 5.

In the Panoramic and TMJ modes, with all interlock enabled, it is possible to activate the TEST push button 31 (see Figure 7-7 at the end of the manual).

The TEST functioning mode allows the operator to check the functionality of the selected examination cycle or to show to the patient the examination he will undergo (including all movements of the machine) without emitting X-rays.

The TEST push button as X-ray button is a "dead man" button, which means thus if it is released during the examination cycle, the latter is interrupted stopping the movements in progress. To re-start the cycle first reset the unit by means of the key 32 (Figure 7-7), than start again the function which was interrupted.

kVp The peak tube potential is directly measured with a non invasive

kVp-meter, accuracy ±3kVp. When performing the measurement, make sure that measuring probe is completely covered by the X-ray beam. A direct measurement of the high voltage can only be carried out by specialized technicians in a suitable testing laboratory as it requires disassembling of the tubehead.

mA The output current is determined by measuring the voltage drop on a

resistor (1kΩ, 5%) using a digital multimeter, connected to the corresponding plugs, as indicated on paragraph 7.4 (digital multimeter set to VDC 20V, 1V=1mA).

t The exposure times are determined by using a timer/counter, having an

accuracy of 0.1%, measuring the duration of part of the voltage applied to the primary side of the tubehead, during the exposure phase.

WARNING: The following test implies X-ray emission; please follow all measures envisaged by local safety regulations. The system is qualified to operate with a maximum line voltage regulation of 3% at 108V, which is the line voltage generating the highest current draw from the line. Check of line regulation: a proper installation has to make sure that the line provided in the facility where the device is being installed, meets the requirement of line voltage regulation. In order to carry out this test proceed as follows:

1. Using a true RMS Voltmeter asses the line voltage value under no load condition (Vn).

2. Select a timer setting of 2 seconds and make an exposure.

3. Using the same RMS Voltmeter, read the line voltage during exposure which is the under load condition (Vi).

4. Calculate line voltage regulation as: ((Vn-Vi)/Vi)x100. To make absolutely sure that the line meets the requirement independently from possible drift of the line voltage during life of the equipment the measured line voltage regulation must be smaller than 2.4%.

5. In case line voltage regulation does not meet the spec, refer to paragraph 5.1 of this manual and consult with a certified electrician or the local Power Company.

5. Press "R" key (32; Reset); the arm will rotate up to reach the 0° position.

6. Read the value of the potmeter voltage on the DVM: if the value is between 160mV and 180mV the position of the micro is already correct and proceed to step 16; if it is outside the range move to next step.

7. Press "T" key to move away the arm of an angle between 45° and 90°.

8. If the reading of the potmeter voltage of step 7 was below the lower limit of the range, move the microswitch so that the arm will reach it earlier than in the previous position; on the contrary if the reading of the potmeter voltage of step 7 was over the upper limit of the range, move the microswitch so that the arm will reach it later than in the previous position. To move the microswitch release the plate supporting it and adjust its position.

9. This procedure is a trial and error process: repeat steps 6 to 9 until the reading of the potmeter voltage with the arm in 0° position is between 160mV and 180mV.

11. Read the value of the potmeter voltage on the DVM: if the value is between 2.00V and 2.30V the position of the micro is already correct and proceed to step 16; if it is outside the range move to next step.

12. Press "R" key (32; Reset) to move away the arm which will go back to 0° position

13. If the reading of the potmeter voltage of step 12 was below the lower limit of the range, move the microswitch so that the arm will reach it later than in the previous position; on the contrary if the reading of the potmeter voltage of step 12 was over the upper limit of the range, move the microswitch so that the arm will reach it earlier than in the previous position. To move the microswitch release the plate supporting it and adjust its position.

14. This procedure is a trial and error process: repeat steps 11 to 14 until the reading of the potmeter voltage with the arm in 245° (STOP) position is between 2.00V to 2.30V.

NOTE: After the above mentioned test, it is suggested to verify and store the start/stop angles following the procedure described at paragraph 7.9.1, steps from 8 to 23. 15. Run the procedure to verify centering and symmetry of the

panoramic, making an exposure on the round centering tool as described in paragraph 7.7.4.

16. On the basis of the values determined for the PAN adult (A2, A3, A4, A5) set the value of the angles A2 and A5 for child as follows:

− A2 child = A2 adult +9°

− A5 child = A5 adult -9°
