INTRODUCTION NOTE: The present manual is updated for the product it is sold with in order to guarantee an adequate reference to perform diagnostics and repairs normally carried out by the service engineer. The manual may not reflect changes to the product not impacting service operations. This manual provides the instructions for proper and safe installation and maintenance of the appliance by technical personnel. This manual is limited to the description of the radiographic equipment; the instructions for the image acquisition, manipulation and processing are given in the user manual supplied with the imaging software used with the I-Max Touch or I-Max Touch 3D unit. WARNING: 1. The I-Max Touch/I-Max Touch 3D is an electro-medical device and it can be used only under the supervision of a physician or of highly qualified personnel, with the necessary knowledge on X-ray protection. 2. The device must be used in compliance with the procedures described, and never be used for purposes different from those herewith indicated. 3. The user is liable with regards to the legal fulfillment related to the installation and the operation of the device. For any technical queries please contact the technical service of your vendor. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 7 SERVICE MANUAL 1.1 Description of the system The I-Max Touch produced by Owandy Radiology is a complete panoramic system that allows for the acquisition of all X-ray examinations commonly used in dentistry and orthodontics (excluding intraoral radiographs): Panoramic, Emi-panoramic, Reduced dose Panoramic, Frontal dentition, Improved orthogonality Panoramic, Bitewing, Sinus, TMJ and Implant examinations of the maxillo-facial complex. The evolution of panoramic X-ray units now provides, in addition to traditional methods of examination (Panoramic, TMJ, Sinus, etc.), the use of three-dimensional images of the patient's maxillofacial complex. This allows the doctor to investigate a targeted selection of the patient's mouth and to use it both during the planning phase of the treatment as well as a diagnostic aid. The I-Max Touch 3D produced by Owandy Radiology is a complete panoramic system that allows for the acquisition of all X-ray examinations commonly used in dentistry and orthodontics (excluding intraoral radiographs) and also allows the acquisition of volumetric tomographic, or 3D, X-rays. In this type of device the linear digital sensor traditionally used in the digital panoramic X-rays has been replaced by a wide range digital sensor also known as a flat panel. These sensors allow for the capture of an area of the maxillofacial complex that includes the most important anatomical details by acquiring a series of two-dimensional images (imaging) and reconstructing it with a computer. These options are available for the I-Max Touch and I-Max Touch 3D and must be ordered separately:  Digital ceph; allows the acquisition of the following exams, available in High Resolution mode or Normal Resolution (high speed): o Ceph exam in different formats. o Carpus exam. 1.2 Physical principles of operation The I-Max Touch (2D) unit uses a CCD sensor that converts the amount of dose that affects every single sensor element (pixel) into an electrical signal that can be processed through an analog-digital conversion system. The digital CCD system of the I-Max Touch is designed by Owandy Radiology. The I-Max Touch 3D uses the Varian PaxScan 1313DX wide range digital system, used for the acquisition of 3D and panoramic type images. The flat panel sensor functions as a normal digital sensor. Unlike traditional sensors used for panoramic exams that normally return one image column at a time, the flat panel returns the entire contents of the sensor. Special functions inside the sensor also allow the acquisition of a specific part of the sensor, functioning as a normal digital sensor. The system must be connected to a dedicated computer, on which is installed all the software needed for image acquisition, processing and display. The resulting images are stored in the system's database in correspondence with the selected patient. The cephalometric images on the I-Max Touch or I-Max Touch 3D are obtained using a cephalometric digital system designed by Owandy, similar to that for the panoramic acquisitions on the I-Max Touch. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 8 SERVICE MANUAL 1.3 Image acquisition on the I-Max Touch 3D Volumetric (3D) acquisitions) In 3D acquisitions a sequence of two-dimensional images is acquired during a rotation of the rotating arm. In this type of acquisition, the X-ray generator is operated in pulsed mode, with short pulses emitted at each degree of the rotating arm. The sequence of images thus obtained is passed to special software residing on the dedicated computer, which uses sophisticated mathematical algorithms to generate the corresponding volume. The spatial resolution of the image obtained is the result of both the size of the sensor's pixels and the quality of the reconstruction software; in this case the resolution is measured in "voxels" (short for VOlume piXEL). The volume thus reconstructed is returned to the image display software, in which different operations are possible that allow the operator or the physician to select which part of the volume to display, to obtain specific sections at a given point, etc. Panoramic image acquisitions Special functions of the flat panel also allow acquiring partial sensor images with a frame rate (acquisition speed) higher than that used for 3D images. In this mode, the X-ray emission is continuous, as in normal panoramic radiography. The sequence of images obtained are the input for special reconstruction software, developed specifically for the I-Max Touch 3D, which allows the reconstruction of the standard panoramic X-ray simulating the physical mechanism of "kinetic cancelation" as used in analogue systems. 1.4 Icons appearing in the manual Indicates a NOTE; please read the items marked by this icon thoroughly. This icon indicates a WARNING; the items marked by this icon refer to the safety aspects of the patient and/or the operator. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 9 SERVICE MANUAL 2. USABILITY The I-Max Touch or I-Max Touch 3D medical system is intended to be used in radiology or dental practices. In the first case the user is either the radiologist or the technician specialized in radiology, in the latter case it is the dentist. The radiologist or the dentist is responsible for the assessment of the risk/benefit ratio. In both cases, these are people who already have basic knowledge about:  Emission of ionizing radiation.  Danger of physical harm related to the excessive use of ionizing radiation.  Methods to reduce the risk of excessive radiation to the patient (use of lead-lined protections, etc.). The operator must be familiar in the use of a personal computer and related programs, in order to use the functions on the computer easily. 2.1 Training The operator training follows at the end of the system's installation and concerns both the use of the system and the image acquisition and display programs. The training does not require the use of special tools. The user manual describes the steps necessary to perform standard panoramic and cephalometric type X-rays and volumetric X-rays (or 3D). 2.2 Patient profile The machine is suitable for all types of patients. Depending on the type of patient, the different execution modes of each examination can be selected on the operating console (adult, child - small, medium or large bone density - 3 types of dentition). 2.3 Prescription use statement (USA) CAUTION: Federal law restricts this device to sale by or on the order of a dentist or any other practitioner licensed by the law of the State in which he practices to use or order the use of the device. 2.4 Indications for use The I-Max Touch and I-Max Touch 3D panoramic X-ray imaging systems with cephalostat are extra-oral source X-ray systems, intended for dental radiographic examinations of the teeth, the jaw and oral structures. It is specifically suited for panoramic examinations, implantology, TMJ studies and cephalometry. It has the capability, using the CBVT technique, to generate dento-maxillofacial 3D images. The 3D unit uses a cone-shaped X-ray beam projected onto a flat panel detector to acquire the data; the examined volume image is then reconstructed to be viewed on 3D imaging workstations. 2D Images are obtained using the standard narrow beam technique. The device is to be operated and used by dentists, radiologists and other legally qualified healthcare professionals. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 10 SERVICE MANUAL 3.

More details about the electronic circuits which compose the system can be obtained by analyzing the schematics provided at the end of the manual. From the electrical point of view, the system can be divided into 4 main blocks:  Power supply assembly  Main CPU board (A5)  Generator board (A10), Generator CPU board (A9) and tubehead  Column CPU board (A1)  Control panel with its electronic board (A4) All control boards above listed are equipped with a local microcontroller that shares information with the main CPU (A5) using a CANBus transmission line and protocol. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 29 SERVICE MANUAL 4.3.1 I-Max Touch block diagram Figure 4 I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 30 SERVICE MANUAL 4.3.2 I-Max Touch 3D block diagram Figure 4 I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 31 SERVICE MANUAL 4.3.3 Power supply assembly It is located in the rear part of the column and is mainly composed by the mains switch (S1), a 24Vdc 7A switching mode power supply which supplies all circuits of the machine excluding the column motor, another power supply which supplies the column motor and the enabling circuit for the X-ray emission. The power supply assembly also acts as an interface with a number of external signals and circuits like:  Input for the remote X-ray push button (S7) and output of the same signal to the CPU.  Outputs for the "Ready" and "X-ray ON" lamps (X3).  Driving of the DC column motor (M1): this motor can be activated either through its control board (A1) in case the movement is requested by the operator acting on the keyboard, or through switch S2 located in the rear part of the column base. This switch can be used to raise or lower the column during the installation phase when the CPU has not yet been connected to the system.  Input for the emergency column motor microswitches (S3 and S5): these microswitches indicate the limits for the movement of the column. If for any reason the column goes beyond these microswitches the motor is deactivated by cutting off the voltage. Normally the position of the column is also monitored by two other microswitches (S4 and S6) that, as for all the other positioning sensors, provide their signals to the column CPU board (A1). The unit does not include a voltage selector circuit for the mains voltage. Therefore, the unit is manufactured in different versions, depending on the line voltage of the installation place. The power supply assembly module also includes the column CPU board (A1) that is dedicated to the control of the vertical column motion during all phases (slow speed, ramp up to high speed, ramp down from high to low speed, end run microswitches control, etc.). 4.3.4 CPU Board (A5 and A6) It is located in the head of the unit. Its main tasks are:  General controlling of the unit, receiving the signals from the keyboard and from the different microswitches.  Driving of the 3 stepper motors which compose the system.  Monitoring the functioning of the motors through the analysis of the signals coming from the positioning sensors.  Driving of the HF group (generator board and tubehead) in order to provide the X-ray doses set by the operator on the keyboard (kV and mA) as well as checking the functioning of this HF group by managing the relevant alarm signals.  Activation of the 2 luminous centering devices.  Managing of the alarms that can be generated by anomalous conditions present in the unit and caused by the operator or by a fault. These signals are sensed by the local CPU boards and signalled using specific CANBus messages. The CPU board is based on a 32 bit Motorola microprocessor MCF5232 mounted on a piggy-back board (A6), which also includes the Flash EPROM, the RAM and other logic and passive components. The CPU board also includes a number of input/output channels necessary for the functioning of the system and 3 stepper motors. Each of these motors is associated to positioning sensors that monitor their functioning; the signals of these sensors are fed back to the CPU board. The number and the type of sensors depend on the function of each motor; in general optical switches are used. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 32 SERVICE MANUAL Depending on the physical location of the motors in the machine, their signals and the ones of the relevant positioning sensors are routed directly to the CPU through dedicated cables or through interconnection boards located closeby. The transmission of the motion from the motor to the relevant movement assemblies is achieved through toothed belts (rotation motor and Y axis motor) or through actuators (column motor, primary collimator, Soft Tissue Filter, secondary collimator and ceph sensor). The functioning of the different motors and relevant positioning sensors can be tested through the use of the service programs (passwords) described further down in this manual. The circuits of the CPU board are supplied starting from the +24Vdc (LED H12) provided by the power supply assembly and generating the requested voltages (+5V, +3.3V and +1.5V). Three LED's on the board indicate the presence of these 3 voltages (+5V=LED H2, +3.3V=LED H3, +1.5V=LED H5). 4.3.4.1 CPU Board jumper configuration I-Max Touch The CPU board contains some jumpers that define the system configuration.

The power supply voltage is provided directly by the p0ower supply assembly. Dedicated switching circuits, directly located on the board, generate the voltage used on the board itself. The management of the generator board is done by the dedicated generator CPU board (A9) that is interfaced with the main CPU board (A5) using a CANBus cable (X20-X20). This cable also has a dedicated wire to bring the X-ray trigger signal to this board to handle the "dead man switch" directly from this board. The high frequency (HF) circuit is based on an inverter circuit working at the frequency of about 100 kHz, which drives the tubehead through an output stage based on IGBT components. The generator board receives the signals about the X-ray dose it needs to provide (kV and mA) from the CPU board through CANBus messages; it is the generator CPU that generates the commands used for the X-ray emission. The generator board provides to the tubehead the voltages that drive the high voltage transformers that then drive the anode and filament of the X-ray tube; it also provides the relevant timing. The tubehead is composed of the X-ray tube (CEI OPX/105) inserted in a sealed container together with the high voltage transformers and filled with dielectric oil. Checking of the proper functioning of the X-ray emitting system is achieved through the analysis of feedback signals generated inside the tubehead and transmitted to the generator board and relevant generator CPU. Possible anomalous conditions are then communicated to the main CPU board (A5) which in turn generates error codes to alert the operator. 4.3.6 Control panel with electronic board (A4) The control panel is the interface with the operator and is composed of the following items:  Matrix of keys constituted by microswitches with a short stroke, necessary to activate the different functions available  Signalling LEDs integrated in the control panel  LCD display equipped with back-light (QVGA) and touch panel assembly  Keyboard electronic board The keyboard electronic board is directly connected to the main CPU board (A5) which controls it. The language of the messages shown on the display can be selected among different options (English, French, Spanish, Italian, Portuguese, German, Dutch and Turkish). The language selection is only available for the user messages; the messages in the service programs are always in English.

Replace after every use. NOTE: These removable parts are considered "type B applied parts" in accordance with IEC 60601-1 2nd edition. Some of these parts do not carry identification codes due to their small size. The use of these parts on other devices is not possible as they are parts designed specifically for the I-Max Touch 3D. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 48 SERVICE MANUAL 5.5 Measurement method technical factors 5.5.1 Invasive method WARNING: These measurements require the removal of the HF group covers; this means gaining access to internal parts where high voltage is normally present. For the measurement of the exposure parameters with the invasive method, please follow the procedure described further down in this manual. WARNING: During the panoramic examination the KV and mA values vary according to a predetermined curve to compensate for the different absorption of the X-rays due to different anatomical structures. This makes it possible to obtain a good uniformity of the image contrast. This is done by lowering the chosen value in the initial phase of the panoramic exam and increased it in the inscissor/canine area to compensate for the denser cervical spine. The value displayed during the panoramic examination corresponds to the one selected by the user while the real value can differ; these effects must be considered when measuring the exposure parameters using a standard diagnostic mode. As an example, the variation follows this curve: 1 Selected value 2 Real mA value 3 Real KV value Accuracy declared on the section "Technical data" is in reference of the actual values of kV and/or mA. The manufacturer guarantees that the accuracy of the loading factors is always in compliance with the international standard for safety of medical devices IEC 60601-1. In accordance with IEC 60601-2-7, the maximum deviation (including the correction and instrument’s accuracy) is less than or equal to ±10% for kV, while for the tube current (mA) it is less than or equal to ± 15%. 5.5.2 Non-invasive method The exposure parameters (kV, time and dose) can also be verified using the so called "non-invasive method".. In this way the exposure parameters can be checked with a non-invasive instrument, please follow the procedure described further down in this manual. WARNING: The machine collimator gives a narrow X-ray beam. Measurement by a non invasive kV meter on a very narrow beam can be difficult and/or unreliable and special probes with reduced sensitive area must be used. It may result helpful to use a fluorescent screen to locate the X-ray beam and consequently position the probe of the kV meter.

WARNING: X-rays will be emitted during these operations. The authorised technicians are therefore recommended to use the greatest caution and to comply with the safety regulations and laws of their country. 7.8.6.1 kVp check Use a multimeter (R input >= 10MΩ) in working conditions VDC and end of scale 5/10V (maximum value 4.3 V); position the cold pole on TP40 (GND) and the hot pole on TP44 (kV) on the generator board (A10). Set these parameters on the unit: 60kV - 6mA - 3s. Acquire an exposure and, considering that the ratio between the value on the voltmeter and the high voltage is 1V= 20kV, verify that the value indicated by the multimeter ranges from 2,85V to 3,15V (3V±5%). Should this last value be outside the specified limit, measure the "set kV" voltage supplied by the CPU by connecting the voltmeter between TP40 GND test points and TP46 kV (located nearby X57). The value on these points must range from 2.7V and 3.3V (3V±3%). If it is out of tolerance replace the generator CPU board (A9) otherwise replace the generator board. Measured values for the different set values are listed in the table below: kV Nominal value Minimum value Maximum value 60 70 80 86 3 3.5 4.0 4.3 2.85 3.325 3.8 4.085 3.15 3.825 4.2 4.515 If all the measures are within the specified range and there is an evidence of performance loss, measure the high voltage supplied by the tubehead and the exposure time using a non-invasive kilovoltmeter with ≤±3kVp tolerance. The high voltage value must be within 8% of the set value while the time value must be within 10% of the set value. If the voltage is not within the expected range replace the tubehead otherwise replace the generator CPU board. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 108 SERVICE MANUAL 7.8.6.2 mA check Use a multimeter (R input >= 10MΩ) in working conditions VDC and end of scale 5/10 V (maximum value 4VDC), position the cold pole on TP40 (GND) and the hot pole on TP29 (mA). Set these parameters on the unit: 60kV - 6mA - 3s. Acquire an exposure and, considering that a ratio 1V DC ≈ 3 mA, verify that the value indicated by the multimeter ranges from 1,86V to 2,138V (6mA±8%). Set 80kV - 12mA - 3s on the unit and acquire a new exposure. After acquisition the value read must range from 3,643V to 4,276 V (12mA±8%). Measured values for the different set values are listed in the table below: mA Nominal value Minimum value Maximum value 6 7 8 9 10 11 12 1.98 2.31 2.64 2.97 3.30 3.63 3.96 1.822 2.125 2.429 2.732 3.036 3.340 3.643 2.138 2.495 2.851 3.208 3.564 3.920 4.277 In case the detected values are outside these ranges, check that the voltage between TP40 (GND) and TP34 (mA) is contained on the above ranges. If not, replace the generator CPU board (A9). 7.8.6.3 Time Verify the accuracy of the exposure time using an oscilloscope connected at the same test points used to measure mA (TP40 for GND and TP29 for mA) of the generator board (A10). The exposure time calculated at about 75% of the maximum kV value must correspond to the set one ±10%. In case the time is outside the prescribed values replace the CPU board. 7.8.7 Verification exposure parameters - Non-invasive method The exposure parameters (kV, time and dose) can also be verified using the so called "non-invasive method". WARNING: The machine collimator provides a narrow X-ray beam. Measurement by a non invasive kV meter on a very narrow beam can be difficult and/or unreliable and special probes with reduced sensitive area must be used. It may be helpful to use a fluorescent screen to locate the X-ray beam and consequently position the probe of the kV meter. The exposure parameters can be checked with a non-invasive instrument by performing this procedure: 1. With the unit switched on select the panoramic examination mode by pressing the "Exam selection" key (9). 2. Press the "Anatomic/Manual" mode indicator (13) until it turns green and displays "S", then press the "Test" key (4); the display will show: xxkV xxmA xx.xs EMISSION PROGRAM I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 109 SERVICE MANUAL WARNING: X-rays will be emitted during these operations.

Power off the unit and, after 1 minute delay, power it ON again. If the error is displayed again replace the microprocessor CPU board (A6). 8.2.1.1 E108: Hardware key fault This error is shown when the firmware of the I-Max Touch 3D does not sense the presence of the U.I.C. (Unique Identification Code). The unique code is read with its check byte from the control system at the startup; if the check byte is incorrect the system displays this error number. In case this error is displayed, pressing the "Patient entrance" key >O< (5) allows the system to continue functioning but only standard basic examinations will be possible. Verify the presence of the key and that is well inserted. In case there is a fault on the hardware key itself it must be replaced and all the optional features must be re-enabled with the proper codes. Before requesting a new hardware key the serial number of the equipment and/or the U.I.C. itself must be recorded and reported to Owandy Radiology. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 117 SERVICE MANUAL 8.2.1.2 E110: Battery fault This message means that the clock battery on main CPU board (A5) is low or faulty. If after the power-on a 90 second cooling time starts, wait until the end of the time, then the display will show "E110 – Press >0<". Follow the instructions shown on the display and acquire an exam. At the end of the exam power off the machine and wait a couple of minutes before powering it on again. If the message is not displayed it means that the battery is low. Leave the machine powered on to recharge it. If the message is still displayed it means that the battery is faulty; replace the main CPU board (A5). 8.2.2 Error codes E200 to E299 These errors are related to the various axis movements and require the replacement of some parts; only error message E206 can be generated by a special condition and can be reset. 8.2.2.1 E200: Zero position optical sensor of rotation always active 8.2.2.2 E201: Zero position optical sensor of rotation never active 8.2.2.3 E204: Unexpected activation of zero position rotation sensor These messages mean that during the rotation there is no change or an unexpected activation of optical sensor B3. The position of the rotation is controlled by optical sensor B3 that is activated at the start of the rotation movement; if this sensor is found active at the start up phase and is never sensed de-activated the E200 message error is displayed meaning that the sensor itself is broken or that the motor is not running. In case that it is never sensed activated the E201 error is displayed for the same reasons. Error E204 means that during some movements the sensor changes its status to "Activated" in an abnormal condition. Entering the rotation motor service program it is possible to check the cause of the error: T ZERO [ff] a ZERO OFFS ±eeeee In normal conditions the display must visualise "X" instead of the character "a". In all cases the sensor’s functionality can be checked by placing an opaque thin material in the optical path and looking at the voltage coming out from the sensor. Using the left and right arrow keys it is possible to rotate the arm while checking if the status of the sensor changes accordingly. If there is no variation of the above signals, if the arm does not move or moves with difficulty or jumps:  Check the belt and verify that it is not broken; if the belt is loose adjust its tension.  Check the cable of the stepper motor, there can be a short circuit or a broken wire; check also for a loose contact. In case of a short circuit replace the cable, verifying also that no damage has been caused to the motor driver (D27) on the CPU. If the arm moves verify the cable up to CPU board (A5). If it still continues to not have a variation of the signals when there is an activation of the switches change the CPU board. 8.2.2.4 E205: Timeout on rotation This message means that no change on the rotation’s signal is detected; please follow the steps described above. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 118 SERVICE MANUAL 8.2.2.5 E206: Patient collision It is caused by a possible collision between the patient and the rotating arm. After removing the patient from the unit, press the patient centering key >O< (5) to restart the power-on procedure and correctly set the unit. If the error message is displayed again there is a fault on the rotation sensing circuit; these steps should be performed:  Check that rotation motor M3 is rotating; if not check the cable from the motor to the rotation group board (A7), connector X61 up to the main CPU board (A5), connector X25/X25.  If the motor is running, check the optical sensor B2 and its cables to X60 of A7 up to connector X25/X26 of main CPU board (A5). Replace the sensor or the faulty cables. 8.2.2.6 E240: Zero position sensor for Y axes always active 8.2.2.7 E241: Zero position sensor for Y axes never active 8.2.2.8 E242: Unexpected activation of Y axes 8.2.2.9 E243: Timeout of Y axes These errors are signalling a problem on the Y axis movement. Entering in the Y-axis service program it is possible to check the cause of the error: Y ZERO [ff] a ZERO OFFS ±eeeee In normal conditions the display must visualize "X" instead of the character "a". Using the left and right arrow keys it is possible to rotate the arm while checking if the status of the sensor changes accordingly. If there is no variation of the above signal, if the arm does not move or moves with difficulty or jumps:  Check the belt and verify that it is not broken; if the belt is loose adjust its tension.  Check the cables of the Y axis motor; there can be a short circuit or a broken wire; check also for a loose contact. In case of a short circuit replace the cable, verifying also that no damage has been caused to the motor driver (D27) on the CPU. If there is no variation of the above signal and the arm moves, verify the cable from the optical sensor up to the CPU board (A5). If there is stil no variation of the signals when there is an activation of the switches change the CPU board. In case of no motion it is possible that the problem is related to the motor: in order to check this connect the driver of the Y-axis motor to the rotation motor, connecting cable X28 to connector X26 on CPU board (A5). 8.2.2.10 E280: Unexpected activation of zero position sensor on ceph 8.2.2.11 E281: Timeout of zero position sensor on ceph 8.2.2.12 E282: Zero position sensor for ceph never active 8.2.2.13 E283: Zero position sensor for ceph always active All these messages refer to the optical barrier that is sensing the zero position of the digital ceph sensor holder; differences are that the first error message (E280) may occur during the examination meaning that the senor activation has occurred before the expected time. This can be caused by the loss of motion of the stepper motor due to a collision with the patient or a fault of the motor stepper driver. In case no collision has been observed or the message is frequently displayed follow the procedure below. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 119 SERVICE MANUAL The last 3 error messages are displayed during the power on phase when the system is controlling the functionality of the whole system. Errors E281 and E282 mean that the zero position sensor is never activated due to a motor that is not running or to a fault of the optical barrier (the sensor or its harness); error E283 means that this sensor is always activated, in this case the problem can also be the motor or the optical barrier.  Check that during the power on phase there are movements on these axes; the normal motion is going to engage the sensor and a reverse motion disengage it. If no motion is observed the problem can be the stepper motor or the cable connecting it to the main CPU. Check that the cables between motor M9 and X6 of board A12 is well inserted and check the cable X1-X2 of A12 to X23, X24 and X34 of the main CPU A5.  Check the continuity of the above cables from M9 to board A12 and from X1-2 of board A12 to X23, X24 and X34 of the main CPU (A5).  Repeat the power on sequence while checking the motion. If still there is no motion replace the stepper motor and if not repaired replace the CPU. If a motion has been observed but messages are displayed the problem can be the sensor or its wiring:  Power off the system and try to manually disengage the sensor with a smooth movement.  Power on the system and check the functioning of the sensor, measuring the DC voltage on the terminal of sensor B10 with and without an obstacle manually inserted. A variation of about 3.5 V minimum should be observed; if not replace the sensor.  If the variation is observed and the message is still displayed check the correct insertion of cable X5 on board A12 and from X1-2 of the board to X23, X24 and X34 of the main CPU; check the continuity of the wires and replace the faulty ones (if any).  If all cables are OK the fault is on the main CPU and it needs to be replaced. 8.2.3 Error codes E300 to E399 8.2.3.1 E300: Unexpected activation of zero position sensor on secondary ceph collimator 8.2.3.2 E301: Timeout of zero position sensor on secondary ceph collimator 8.2.3.3 E302: Zero position sensor for secondary ceph collimator never active 8.2.3.4 E303: Zero position sensor for secondary ceph collimator always active The X-ray beam coming out of the tubehead assembly is collimated to the area required for the exam by a secondary collimator that is moving synchronously with the ceph sensor holder; this collimator is moved by stepper motor M7. All these messages refer to this mechanism; all the procedures described above for errors E280 to E283 for patient collision are applicable. In case of absence of collision between the secondary collimator and the patient the cause can be a fault on motor M8 and/or optical sensor barrier B11.  Check that during the power on phase there are movements on these axes; the normal motion is going to engage the sensor and a reverse motion disengage it. If no motion is observed the fault can be the stepper motor or the cable connecting it to the main CPU (A5). Check that the cables between motor M7 and X4 of board A12 is well inserted as for cable X1-X2 of A12 to X23, X24 and X34 of the main CPU.  Check the continuity of the cables mentioned above from M7 to X4 of board A12 and from X1-2 of A12 up to X23, X24 and X34 of the main CPU.  Repeat the power on sequence while checking the motion. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 120 SERVICE MANUAL If there is still no motion replace the stepper motor and if not fixed replace the CPU. If a motion has been observed but messages are displayed this can be due to the sensor or its wiring.  Power off the system and try to manually disengage the sensor with a smooth motion.  Power on the system and check the functioning of the sensor, measuring the DC voltage on the terminal of sensor B11 with and without an obstacle manually inserted. A variation of about 3.5 V minimum should be observed; if not replace the sensor.  If the variation is observed and the message is still displayed check the correct insertion of cable X3 on board A12 and from X1-2 of the board up to X23, X24 and X34 of the main CPU; check the continuity of these wires and replace the faulty ones (if any).  If all cables are OK the fault is on the main CPU and it needs replacing. 8.2.3.5 E320: Unexpected activation of zero position sensor on primary collimator 8.2.3.6 E321: Timeout of zero position sensor on primary collimator 8.2.3.7 E322: Zero position sensor for primary collimator Ceph never active 8.2.3.8 E323: Zero position sensor for primary collimator Ceph always active All the messages refer to the optical barrier that is sensing the zero position of the primary beam collimator that is moved by a stepper motor. This mechanism is located in front of the tubehead assembly. The slit collimator does not move during the pan examination while it has a scanning motion during ceph exams that is synchronous with the secondary collimator and the ceph sensor holder. The first error message E320 may also occur at the end of an examination while the system is checking if the motion is correct, meaning that the senor activation has occurred before the expected time. This can be caused by the loss of motion of the stepper motor. The last 3 error messages are displayed during the power on phase when the system is controlling the functionality of the whole system. Errors E321 and E322 mean that the zero sensor position is never activated due to a motor not running or to a fault of the optical barrier (the sensor or its harness); error E323 means that this sensor position is always activated, in this case the fault can also be the motor or the optical barrier.  Power off the system and remove the front cover of the tubehead assembly.  Check that during the power on phase there are movements on the primary slit collimator; the normal motion is going to engage the sensor and a reverse motion disengage it. If no motion is observed the fault can be stepper motor M5 or the cable connecting it to the main CPU. Check that the cables between motor M5 and X64 is well inserted as for the cable X64 to X29 and X30 of the main CPU A5.  Check the continuity of the above cables from M5 to X64 and from X64 to X29 and X30 of the main CPU A5.  Repeat the power on sequence checking the motion. If there is still no motion replace the stepper motor and if not fixed replace the CPU. If a motion has been observed but messages are displayed this can be due to the sensor or its wiring.  Power off the system and try to manually disengage the sensor with a smooth motion.  Power on the system and check the functioning of the sensor, measuring the DC voltage on the terminal of sensor B8 with and without an obstacle manually inserted. A variation of about 3.5 V minimum should be observed. If not replace the sensor.  If the variation is observed and the message is still displayed check the correct insertion of the cable from sensor B8 to X58 and from that connector to X31 of the main CPU A5; check the continuity of these wires and replace the faulty ones (if any).  If all cables are OK the fault is on the CPU and it needs replacing. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 121 SERVICE MANUAL 8.2.3.9 E340: Sensor holder not in pan position An exam requiring the sensor holder in the pan position has been selected but it is not sensed in the proper position. Close the pan sensor holder to its position and press the "Patient centering" key >O< (5) to restart the power on procedure. If this does not reset the error message check the proper functioning of optical sensor B6 and check the continuity of cables from the optical sensor to board A8, connector X48, and from that board to the main CPU board (A5), connector X33. 8.2.3.10 E360 and E361: X-ray trigger pressed during power on This message is displayed if during the power on procedure the local (error E360) or remote (error E361) Xray trigger has been sensed as pressed. Release the trigger if it was pressed; the error condition is reset powering the unit off and on again. If the error is still present:  Check the continuity of the cables of the X-ray trigger; the local trigger S8 is connected to X18 of the control panel and is transferred to the main CPU using the CANBus cable.  Check that cable X18-X18 to the main CPU is well inserted and check its continuity.  From the main CPU the signal is routed to the generator board (A10) using CANBus cable X20-X20; check also that this cable is well inserted and check its continuity. Replace it if damaged.  If the error is still present check the correct insertion of the flat ribbon cable from the generator CPU board (A9) to the generator board (A10). The cable is labelled X53-X53; replace it if damaged. WARNING: On generator board (A10) there are dangerous high voltages, 230 VAC and 400 VDC. Before accessing the generator CPU and power board (A9 and A10) it is mandatory to switch off the mains and wait up to 2 minutes in order to allow the discharge of the capacitors. 8.2.3.11 E362: X-ray trigger released during examination procedure The X-ray emission is controlled using a "dead man's switch"; this means that the X-ray trigger must be pressed until the end of the emission and this also during the interrupted emission phase of TMJ. If this does not happen this error message is displayed; the emission is stopped and all motors are released in order to allow the patient to exit the unit. Press reset button >O< (5) and restart the acquisition keeping the X-ray trigger pressed unitl the end of the acquisition. 8.2.3.12 E363: TCP-IP connection problem This error appears when the TCP-IP connection between the VDSIB board and the computer encounters problems (delay or timeout) which can stop the X-ray emission. If restarting the unit and the computer does not help, check the Ethernet cable between the unit and the computer; make sure the Intel Pro 1000 network board is used to connect the unit to the computer. If the error persists verify if the cables of the VDSIB board are connected correctly; otherwise replace the VDSIB board. 8.2.3.13 E380: Invalid CANBus message (from generator CPU board A9) This error is displayed when the main CPU board (A5) receives an invalid message from the generator board (A10); this is a message whose contents are not listed on the valid data dictionary of the unit. This can be generated by a bad connection or by a fault of the local generator CPU board (A9). Check CANBus cable X20-X20 and replace it if faulty, otherwise replace the generator CPU board and then the generator board. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 122 SERVICE MANUAL 8.2.3.14 E381: Timeout on activating CAN protocol on generator board 8.2.3.15 E382: HF not answering to CAN protocol These two error messages have the same meaning: there is no answer from CAN messages to the main CPU but they occur at different times. Error E381 is generated during power on while error E382 is displayed after a normal power on sequence. In both cases the error can be generated by a bad connection of the CANBus or a fault on the local generator CPU board so the steps described above for error E380 need to be applied. 8.2.4 Error codes E400 to E499 8.2.4.1 E400: Timeout of zero position sensor on Soft Tissue Filter 8.2.4.2 E401: Zero position sensor for Soft Tissue Filter always active The Soft Tissue Filter for cephalometric exams is controlled by a stepper motor. During power on the system checks if the motion is correct, checking the activation and deactivation of optical sensor B9. If it is not sensed activated timeout message E400 is displayed; while if it is always active, error E401 is displayed. In both cases the error can be generated by the loss of movement of the stepper motor or by a fault of sensor B9.  Power off the system and remove the front cover of the tubehead assembly.  Check that during the power on phase there are movements on the primary slit collimator; the normal motion is going to engage the sensor and a reverse motion disengage it. If no motion is observed the problem can be stepper motor M6 or the cable connecting it to the main CPU. Check that the cables between motor M6 and X65 are well inserted as for cable X65 to X29 and X30 of main CPU board A5.  Check the continuity of these cables from M6 to X65 and from X65 to X29 and X30 of main CPU board A5.  Repeat the power on sequence checking the motion. If there is still no motion replace the stepper motor and if not fixed replace the CPU. If a motion has been observed but messages are displayed this can be due to the sensor or its wiring.  Power off the system and try to manually disengage the sensor wuth a smooth motion.  Power on the system and check the functioning of the sensor, measuring the DC voltage on the terminal of sensor B9 with and without an obstacle manually inserted. A variation of about 3.5 V minimum should be observed; if not replace the sensor.  If the variation is observed and the message is still displayed check the correct insertion of the cable from B9 to X33 of the main CPU board and the continuity of the connection.  If all cables are OK the fault is on the CPU and it needs replacing. 8.2.5 Error codes E700 to E799 WARNING: These errors are related to the X-ray generator, so they can be safety related. In case of error messages E759 and E755 the system must be immediately powered off because there is an unexpected X-ray emission (error E759) or the emission has not been terminated in the expected time. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 123 SERVICE MANUAL WARNING: On the generator board (A10) there are dangerous high voltage, 230 V AC and 400 VDC. Before accessing the generator CPU and power board (A9 and A10) it is mandatory to switch off the mains and wait up to 2 minutes in order to allow the discharge of the capacitors. 8.2.5.1 E750: No power to generator board This message is signalling that the generator board (A10) is not powered. Check if LED H3 of the generator board is ON; if that is the case check the insertion of connector X53 and insert it correctly if necessary. Check the voltage between TP21 and TP22, it should be 10V DC ±2V; if the value is inside the range replace the generator CPU board (A9). If the value is zero (or very low) replace the generator board. If LED H3 is off apply the operations as described in the previous subchapter. 8.2.5.2 E751: Overvoltage kV This message is displayed when a value higher than expected has been detected on the generator board (A10). Check that connector X57 is well inserted. With the connector inserted, measure the resistance between pins 2 and 4 of the connector (harness to tubehead) that should be 13,3k ±2% while it should be 14,3k ±2% between pins 4 and 3 of the same connector; if correct values are measured replace first the tubehead and if necessary the generator board. If incorrect values are measured replace the tubehead, then the generator board. 8.2.5.3 E752: Filament overload 8.2.5.4 E753: Overload on anodic current These messages are displayed when an abnormal value for the filament current or anodic current has been detected. Replace the tubehead, then the generator board. 8.2.5.5 E754: Broken filament This message is displayed when there is a fault on the power circuit of the filament and not only on the filament itself. Check that connector X56 is well inserted. Check the continuity of the wires from X57 to the tubehead. Verify if the preheating parameters are correct. If all is OK replace the tubehead. 8.2.5.6 E756: PFC failure This message is signalling that the PFC (Power Factor Control) circuit is not correctly functioning. If the error is present in stand-by mode replace the generator board (A10). If the error appears during an exposure reset the error and repeat the exposure; if the error still appears replace the generator board, then the tubehead. I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 124 SERVICE MANUAL 8.2.5.7 E755: Alarm “Backup timer intervention” 8.2.5.8 E758: Alarm “No X-ray” 8.2.5.9 E759: Alarm “Unexpected emission” Check if the X-ray emission is correct by measuring the anodic current against the set nominal value on the generator board (A10). When the system is in idle mode, in a non emitting state, this signal must be low; the generator CPU board (A9) checks this condition. If this does not happen the E759 message is displayed. The CPU command for the emission, the X-ray on signal, is set to the on condition when it reaches 75% of its set value at the beginning and is higher than 25% at the end of emission. If the first condition is not met the exam is halted and the system has to be reset; message E758 "No X-ray" is displayed. In this case check the correct insertions of cables X56 and X57 between the generator board and the tubehead and X53-X53 (flat ribbon cable) between the generator board (A10) and the generator CPU board (A9). Check the CANBus connection between the generator CPU board (A9) and main CPU A5 (cable X20-X20). If all the connections are OK and the fault is repetitive apply the procedure for LED H1 (see LED subchapter). If the second condition is not met and the X-ray emission does not drop below the value in a pre-set time, message E759 "Unexpected emission" is displayed. This message can be also displayed if the X-ray on signal is sensed during the idle state. In this case check the main CPU board (A5) and the generator CPU board (A9) and cable X20-X20. If all are OK replace the generator board. The emission is also controlled through a safety backup timer that interrupts the power to the tubehead in case of a hardware or software fault in the generator CPU board. The intervention of the backup timer, message E755, is signalled by red LED H4 lighting up. This alarm can be reset only by powering off the unit and waiting for at least 1 minute before powering it on again. If LED H4 remains lit (on) replace the generator board. If the LED does not remain lit (off) after powering on the unit make a new acquisition and replace the generator board if the message appears again. 8.2.5.10 E760: Alarm "No X-ray trigger command" This message is displayed when the generator CPU board (A9) is not detecting the X-ray trigger during the emission start-up. In this case check the correct insertion of X53-X53 (flat ribbon cable) between the generator board and the generator CPU board (A9). Check the CANBus connection between the generator CPU board (A9) and main CPU A5 (cable X20-X20). If the error is still present check the cable of the X-ray trigger; If all connections are OK and the fault is repetitive replace the generator CPU board (A9). 8.2.5.11 E762: Alarm "No X-ray feedback" This message is displayed when the generator CPU board (A9) is not detecting the X-ray emission feedback signal. In this case check the correct insertion of X53-X53 (flat ribbon cable) between the generator board and the generator CPU board (A9). Check the CANBus connection between the generator CPU board (A9) and main CPU A5 (cable X20-X20). Check the correct insertion of cables X56 and X57 between the generator board and the tubehead. If all connections are OK and the fault is repetitive replace the generator CPU board (A9). I-Max Touch / I-Max Touch 3D – Ver. 4 Page: 125 SERVICE MANUAL 8.2.5.12 E771: Frame longer that expected 8.2.5.13 E772: Invalid analog channel selection 8.2.5.14 E773: Unknown command Protocol errors; power off the unit and on again. If the error is still present call the technical service department. 8.2.5.15 E774: X-ray trigger not pressed This error message is displayed when the generator CPU board (A9) is not detecting the X-ray trigger activation; it is also displayed if the main CPU (A5) has launched the emission with the corresponding CANBus message. In this case a possible interruption on cable X20-X20 from main CPU A5 to generator CPU board A9 is possible. From the main CPU the signal is routed to the generator board using CANBus cable X20-X20; check that this cable is well inserted and check its continuity and replace it if damaged. If the error is still present check the correct insertion of the flat ribbon cable between the generator CPU board and the generator board. The cable is labelled X53-X53; replace it if damaged. 8.2.5.16 E775: X-ray trigger released during emission This message has the same meaning as error E362 but is generated by the generator CPU board (A9); it is signalling a possible broken connection with the main CPU (A5). Repeat the test as for error E774 above. 8.2.5.17 E776: Watch dog CAN intervention Protocol error; power off the unit and on again. If the error is still present call the technical service department. 8.2.6 Error codes E800 and E801 These messages are signalling an error caused on the column movement. 8.2.6.1 E800: Timeout on CAN activation for vertical motor This error is displayed when there is no answer from CAN messages to the main CPU board (A5) during power on.

This is due to the fact that the new CPU board, provided as a spare part, has been factory tested from the functional point of view, but contains only default parameters which are not related to the unit where it will be installed. Entering of the listed parameters can be performed through the service programs (passwords) - for more information refer to the Technical service programs chapter. NOTE: The data listed in the table are the technical parameters set during factory testing. Preferences set by the user (e.g. exposure parameters different than the default ones) are not listed. The table also contains columns with blank cells; those cells must be filled in when during installation or during the life on the unit any of the listed parameters are modified (e.g. after replacing a motor or a positioning sensor).
