It can be extended or retracted and moved up and down while keeping the tubehead balanced in the position it has reached. An additional extension arm is attached to the arm which is available in three different lengths: 15.75 in (40 cm), 23.6 in (60 cm) or 34.25 in (87 cm). X-ray tubehead with collimator The X-ray tubehead is self-contained and due to its operating characteristics, the exposure time can be reduced so that less radiation is absorbed by the patient. Moreover, the tubehead is provided with a collimator (cone) capable of operating at a minimum skin/focus distance of 7.88 in (20 cm); the maximum diameter of the X-ray beam is 2.17 in (5.5 cm). The X-ray tubehead is attached to the arm in such a way as to permit unlimited rotation. With this arrangement it can be rotated 360∞ on its horizontal plane while the rotary movements on the vertical plane are limited by the collimator. Micro-processor X-Mind control panel The microprocessor-based control system is used to automatically set the exposure time from a minimum of 0.02 s to a maximum of 3.00 s. The electronic controller automatically determines the exposure time according to the changes in the electrical supply and in relation to the rated voltage (in the range of + 10%). The standard version of the controller can operate up to two X-ray tubeheads. By adding an optional device to the controller, up to four X-ray tubeheads can be operated.

Basic patient position The patient should be positioned on the table in whatever position that is appropriate for the radio- graph to be taken. A3.2. Positioning the X-ray tubehead assembly Position the tubehead by moving the double-jointed pantograph arm so as to bring the collimator into contact with the patientís skin at the point where the radiograph is to be made. The X-ray tubehead is set to the correct position by using the bisecting angle technique A3.2.1. Bisector technique a) Vertical incidence angle of the main beam: In order to obtain a precise image of the tooth, the main beam must be perpendicular to the bisector of the angle created between the longitudinal axis of the tooth and of the film. Having positioned the tube head and the film, as said above, an average incidence angle can be used for each area. The incidence angle of the main beam can be determined by using the graduated scale located on the bracket of X-ray tube. The diagram at the side shows an example of posi- tioning the x-ray cone using the bisecting technique. 13 A3.2.4 Interproximal radiographs To carry out this type of radiograph, the tubehead must be perpendicular to the surface of the film. A3.3. Turning on the X-Mind control Use the main switch (a) to turn ON the control unit. The green light built into the switch will come ON to indicate that power is being delivered to the control unit. All the indicator lights come on and ì8 8.88î will be shown on the display. IMPORTANT Each time the unit is turned ON, the equipment runs a test which lasts 10 seconds. During this time, no radio- graphs will be produced. A3.4. Operating modes The operating modes are determined when the equipment is installed and can only be modified by AFP Imaging Corp. authorized technicians. Always prepare the patient before exposure with appropriate protective shields, aprons or equivalent de- vices to protect the patient from unnecessary radiation. 14 A3.4.1.Use of the equipment with one tubehead When the equipment is installed with one tubehead, the display shows the sensitivity of the film. 15 A3.5. Setting the exposure time To set the radiation exposure time, the following operations must be carried out: ∑ Press the key corresponding to the type of dog tooth being radiographed. Otherwise press the key for upper or lower cat jaw radiographs or the ones for paw or exotic radiographs. The light built into the key that has been pressed will light-up. ∑ Press the key which corresponds to the jaw size of the patient. i.e. a Small or light jaw b Medium or average jaw (default) c Heavy or dense jaw ∑ Set the sensitivity level for the film used (see chart) by using the (f) key. WARNING! The green light comes on to indicate that the equipment is READY for emitting X-rays. The X-Mind control stands by for 30 seconds after which it will terminate and needs to be reset if no radiographs are made. ∑ If an electronic radiographic sensor is used (instead of film), press the DIGITAL key. In this case, the exposure time will be less than 80% in comparison with the normal time needed for producing images on film. ∑ Move to a shielded or safe location before exposure. Use caution in the area where the X-rays are to be emitted. Press the radiation control button and hold it down. The yellow light will come on together with an audible warning device which will continue sounding until the X-ray emission has been completed. IMPORTANT! The radiation control button must be held down during the entire expo- sure! If the button is released prema- turely, X-ray emission is interrupted and the radiograph may be underexposed.

Exposure time chart This chart shows the exposure time (in seconds) for radiographs with the standard film sensitivity of 4 and the equipment running at the rated voltage. The first column indicates the type of teeth or radiograph. The second column shows the degree of suggested inclina- tion as indicated on the relevant dial located on the X-ray tubehead. The third column indicates the exposure time for animals with light jaws, the fourth the exposure time for animals with medium or average jaws, and the fifth that for animals with large or dense jaws. If an electronic radiographic sensor is used (instead of film), press the DIGITAL key. In this case, the exposure time will be less than 80% in compari- son with the normal time needed for producing images on film. 17 Selecting film sensitivity with the key: Start off with the standard setting of 6 first. If more density is needed, try settings higher than 6. If less density is needed, try settings lower than 6. The above chart shows the amount of exposure time variation for the different film sensitivity values Radiograph-film correction chart Sensitivity Standard Variation coefficient 1 0.500 - 50 % 2 0.630 - 37 % 3 0.800 - 20 % 4 1.000 0% 5 1.250 + 25 % 6 1.600 + 60 % 7 2.000 + 1 00 % 8 2.500 + 150% 9 3.200 +220% NOTE: If the range of variation of the actual supply voltage is greater than +/- 10% of the rated voltage, the equipment will not emit X-rays. The chart shown on the right shows the time correction coefficients in relation to supply voltage variations. The correct exposure time is shown on the display when the radiograph has been produced. The timerís software will automatically compensate for line voltage variations by increasing or decreasing the exposure time accordingly. -10,00 % 1.338 -9,54 % 1.318 -9,09 % 1.298 -8,64 % 1.279 -8,18 % 1.261 -7,73 % 1.244 -7,27 % 1.227 -6,82 % 1.211 -6,36 % 1.195 -5,91 % 1.179 -5,45 % 1.163 -5,00 % 1.147 -4,54 % 1.132 -4,09 % 1.117 -3,64 % 1.102 -3,18 % 1.088 -2,73 % 1.074 -2,27 % 1.061 -1,82 % 1.048 -1,36 % 1.036 -0,91 % 1.024 -0,45 % 1.012 0,00 % 1.000 +0,45 % 0.988 +0,91 % 0.976 +1,36 % 0.964 +1,82 % 0.952 +2,27 % 0.940 +2,73 % 0.929 +3,18 % 0.18 +3,64 % 0.907 +4,09 % 0.897 +4,54 % 0.887 +5,00 % 0.877 *5,45 % 0.867 +5,91 % 0.857 +6,36 % 0.848 +6,82 % 0.840 +7,27 % 0.832 +7,73 % 0.825 +8,18 % 0.819 +8,64 % 0.813 +9,09 % 0.808 +9,54 % 0.804 +10,00 % 0.801 % Line % Coefficient voltage variation 18 POSSIBILITIES DEFECTIVE EXPOSURE DEVELOPING STATE OF THE POSITION IMAGES TIME TIME BATHS Underexposed Too short Too short Cold Overexposed Too long Too long Hot Lack of detail Too short Cold or depleted Blurring or Patient moved during double image exposure Distorted Film bent during exposure Not centered incorrect angle Teeth elongated Incidence angle of center beam too horizontal teeth shortened Incidence angle of central beam too vertical Too light or Fixing time transparent too long Not transparent Fixing time enough too short A4. Film developing A4.1 Automatic Processor Automatic film processors designed for processing dental films with RP type chemicals (such as the DENT-X Excel or 810 Basic) control all of the processing parameters (such as temperature, time, washing and drying) automatically. When set up and maintained properly, they will develop the images with very little attention required by the operator. A4.2 Manual Hand Tank Processing In order to obtain good quality images, the film must be developed by carefully following the instructions below: 1.) Remove the film from the package in a dark room taking care not to damage it with fingerprints or scratches. 2.) Immerse the film in the developer and shake it for a few seconds then leave it for 5 minutes at a temperature of 68∞F (20∞C), 6 minutes at 66∞F (18∞C) or 4 minutes at 72∞F (22∞C). 3.) Rinse in running water for approx. 20 seconds. Immerse the film in the fixing agent, shake it for a few seconds and leave it there for at least 5 minutes. 4.) Wash the film in running water. This operation and the ones that follow can be performed outside the dark room. Dry the film in the open air away from dust. 5.) The slightest amount of fixer will contaminate the developer solution. Never move a film from the fixer solution back into the developer solution. It is extremely important to use fresh chemicals dispensed in the correct proportions. Do not add developer to make the baths stronger as this increases contrast but reduces detail. 19 A5. Cleaning and disinfection The external surfaces and parts of the equipment must be cleaned and disinfected. Clean with warm water and mild detergent (optional), using a soft cloth. Disinfect with a disinfectant such as ìCavicideî or equivalent. Take care not to get any of these on the x-ray port. Never immerse the tubehead or timer control in water or other liquids. The wide variety of pharmaceuticals and chemi- cals used in dental operatories can damage coated and plastic parts if not compatible with these products. Tests and research carried out have shown that parts cannot be completely protected from the aggressive action of all products available on the market. The aggressive effects of these products depends on the length of time they are left on the parts. It is therefore important to remove these sub- stances from the equipment quickly. IMPORTANT! Do not use products containing methylated spirits, ammonia or benzol. The material used for cleaning and disinfection should be thrown away afterwards. How to dispose of the waste products. When disposing containers of disinfectant, be sure to abide by local and national regulations. A5.1. Cleaning and disinfection instructions Instruments. Use soft, non-abrasive, disposable paper or cloth for cleaning and disinfection. Do not use sponge cloths or any other re-usable material. Procedure. Cleaning and disinfection are two closely related operations and should be performed together. This is to protect the user from contact with contami- nated parts and to avoid the danger of spreading the contamination when wiping the parts. Pre-disinfection: If the parts are extremely dirty or contaminated, soak disposable paper or cloth with plenty of ìCavicideî or equivalent disinfectant. Using the paper or cloth, generously apply the disin- fectant to the contaminated parts in order to cover them thoroughly (be careful to prevent seepage). Wait 10 minutes to allow the disinfectant to eliminate the bacteria and remove the organic deposits. Cleaning: at this point, take a new piece of disposable paper or cloth soaked with disinfectant or warm water and wipe the dirty parts. Disinfection: soak clean paper or cloth with disintectant and go over the parts to be disinfected again. Leave on for 10 minutes and then remove the residue with dry disposable paper or cloth. If the parts are not particularly dirty, the Pre-disinfection stage can be omitted and it is possible to go straight to the Cleaning stage. 20 A6. Maintenance Preventive maintenance is described in Section B3 under Installation . Any servicing should be carried out by qualified service personnel. A6.1. Periodic maintenance Every year: Perform radiation emission testing as required by your local codes. Check the labels located on the control panel and X-ray tube for condition. Check the exterior of the equipment for damage that may reduce protection against radiation. Make sure the double-jointed pantograph arm is properly balanced. Lubricate the pivot bushing and the pivot pin, located between the arm and the tubehead, with MOLIKOTE D graphite-based grease or equivalent. Check the earth ground connection.

Pre Installation requirements Determine if the optional large Wall Mounting Plate will be necessary. If not, the wall mount pivot assembly used to mount the X-ray support arms and tubehead must be firmly secured to the wall. Use fasteners suitable for the site conditions and have an adequate load capacity (i.e. capable of withstanding a 390 Lb / 177 Kg total load). In the presence of concre- te or brick walls, use anchor bolts. As an alternative, resinbonded anchor bolts can be employed: For Wall Plate Only: (6) Pieces 5/16î diameter bolts and wall plugs or expansion anchors (1) Piece 1/4î Dia X 2 1/2î long flat head wood screw or equivalent on center (6) Sets of bolt head covers are supplied System shown on new optional Steel Wall Plate 28 NEW STEEL WALL MOUNTING PLATE TO FACILITATE IMAGE VET 70PLUS AND X-MIND TIMER INSTALLATIONS AFP KIT PN 9992700112 Effective June 1, 2002, AFP is pleased to introduce a new, optional, steel fabricated Wall Mounting Plate (AFP Plate only is P/N 897-000007) which will be available for all Image Vet 70PLUS sales and installations. Although the current, white surfaced, Wooden Wall Plate AFP (P/N 9992700109) has been in use since 1993, and will remain available, we have often received comments that when the building wall structure is not rigid enough to support the cantilevered weight of the X-ray tube, the wall and the Wall Plate will bow. This was most common when using the longest (90 cm) Extension Arm AFP (P/N 9992700108). To solve the problem with the Wooden Wall Plate, a centrally located, 3î long wood screw was added to the instal- lation kit to fasten the center to a wall stud and prevent the bowing. However, if the internal wall studs (2x4, 2x6, or metal studs) were not exposed during room preparation and were not doubled up to receive the 3î screw or bolt, then the problem was not adequately solved. The new Optional Steel Wall Mounting Plate eliminates any bowing problems, provided it is installed according to AFPís instructions. Please note the Steel Wall Plate is a little larger overall with the six vertical bolt hole patterns increased in length, compared to the Wood Plateís, but the horizontal 16î stud centers remains the same. The new steel Wall Plate fabrication is 1 ºî thick compared to the æî thick wooden one. AFP appreciates feedback from our sales organization as well as from our dealers/customers as we still strive to improve our products. Our ISO 9001 corporate goal is ìCustomer satisfaction through continuous improvementî.

Wall Mounting bolt hole pattern is on standard 16î centers horizontally and 7î centers vertically. No extra screw is required to prevent bowing. The hollow, steel box design and construction allows for internal (hidden) wiring and interconnection of components. 2) Before installation, review site specifications, chair location in the room layout, 115 Volt power supply location and wall mounting location. Respecting local x-ray safety codes, determine the most suitable location for the operator of the X-Mind Timer Hand Control, which includes a 12 foot extension coil cord. 3) Choice, at time of installation: X-Mind Timer can now be mounted directly on the Wall Plate to left or right of the Wall Pivot Assembly which supports the x-ray tube. Alternatively, X-Mind Timer can be located elsewhere in the operatory to suit the specific site plan or local x-ray safety codes. 4) Two sets of pre tapped # 10-32 holes are provided to mount the X-Mind Timer to the left or right of the Wall Pivot Bracket plus there are two æî diameter wire access holes. Alternatively, surface mounted or internal wall wiring can be used to connect the components, if the Timer is mounted elsewhere. 29 5) Determine the best location of the Wall Mounting Plate. Use the Template (P/N 897-000009) information to determine the reach of the x-ray tube support system towards the operatory chair and patient so sufficient coverage will be achieved. 6) Prepare or plan the most desirable wiring method for the X-Mind Timer in the operatory site considering the location of an available 115 Volt power supply. 7) Mark the six Wall Mounting Plate bolt hole locations on the wall, in alignment with the internal wall studs or other sufficient support means. DO NOT MOUNT WALL PLATE AT THIS TIME. 8) Determine if external surface wiring or internal to the wall wiring will be used to provide 115 Volts to the X-Mind Timer control. If the X-Mind Timer Control will be mounted directly to the Wall Plate then only the 115 Volt power supply should be routed to the Wall Plate location. 9) If X-Mind Timer will be mounted directly to the Wall Plate, before mounting anything on the plate prepare three ìjumperî wires (black, white and green/ground or three different colors) of sufficient length (14 gauge x 24î long) from the appropriate æîdia. access hole thru the plate interior and exiting at the central 2îdia. wire ac cess hole. Later, when the Timer and Wall Mount Pivot Assembly are actually mounted, these wires will be trimmed to suit the terminal strip. DO NOT MOUNT X-MIND TIMER TO WALL PLATE AT THIS TIME. 10) If the X-Mind Timer will be mounted to the Wall Plate, route the 115 Volt Power Supply to a point central to the Wall Plate location using surface wiring or internal wall wiring. Allow a 24î pigtail of the 115 Volt supply line and ground to exit from the wall. If the X-Mind Timer will be located elsewhere, route the 115 Volt power supply wires to the X-Mind location. Route three wires (115Volts plus ground) from the Timerís location back to the Wall Plate location. 11) Using six appropriate 5/16 dia. lag bolts or toggle bolts (DO NOT USE PLASTIC WALL SHIELDS) fasten the Wall Plate to the wall after routing the 24 inch 115 Volt power supply pig tail through the selected æîdia. X-Mind Timer wire access hole. 12) Mount the Wall Mount Pivot Assembly on center of the Wall Plate using four 5/16-18 Allen Cap Screws. Note: The top two screws will be visible, therefore they will utilize mounting disc under the head of the screw and two white plastic covers. 13) Mount the X-Mind Timer to the wall plate using two 10-32 screws. Route the power supply wires and two jumper wires thru the access cut out in the X-Mind Timer for termination on the terminal strip. See Section B2.2 for detailed electrical connection information. 14) Trim and terminate the two jumper wires on the Wall Mount Pivot Assembly terminal strip as per Section B2.2 (Electrical) 15) Mount Extension Arm, Pantograph Arm and X-Ray Tube as per section B2.1 16) Insert six 1îdia. white plastic hole plugs to finish appearance. Insert æ inch dia. white plastic hole plugs and two 10-32 screws to fill the unused holes in the Wall Plate. 17) Attaching Trim Covers for exposed Mounting Bolts. See Secion B 2.1 In the Installation Manual, ìInstalling X- ray Equipmentî, page 31. The Extension Arm Mounting Wall Pivot Assembly and Wall Bracket are three names for the same component used to support the system. This assembly has two visible mounting holes just above the two rubber bumpers and two mounting holes located under/inside the Wall Pivot Mount cover. To improve the appearance of the final installation, the factory has supplied additional bolt trim covers (white plastic) and mounting discs that go under the head of the bolts, similar to a large washer. These are the same bolt trim covers used when installing on the large wooden or steel Wall Mounting Plate shown on page 30. 30

Wood Wall Mount Plate Kit P/N 9992700109 31 B1.4. Pre Installation electrical requirements. Refer to wiring diagrams included with the unit Installation method and materials must be in compliance with local electri- cal codes. Determine if supply wiring will be internal to the wall or surface mounted. Confirm that installation is for 115 VAC operation. Control unit power supply Electrical power must be supplied to the control unit through a 3 conductor, 16 AWG power cord. NOTE: The X-Mind control is provided with a 10 A, On-Off switch. The main or primary power source or supply (LINE, NEU- TRAL & EARTH) must be controlled by an independent cut-off switch or circuit breaker as specified by local electrical standards. Determine the best location for the x-mind timer with respect to the wall pivot mount. Take into consideration the location of operatory equipment and a safe location for the operator when exposing x-rays. Connecting the X-Mind timer to the wall mount pivot assembly X-ray tubeheads must be connected to the control unit by using the following wire conductors: Wiring from X-Mind Timer to X-ray tubehead: Black or brown, 16 AWG supply wire White or blue, 16 AWG neutral wire Yellow-green earth wire. 16 AWG or larger For the size of the earth ground conductor, see chart: Max. length of Min. gauge of conductor (feet/m) earth conductor (AWG) 10/3 16 16.5/5 14 26.25/8 12 39 - 49/12 - 15 10 IMPORTANT: While wiring, allow for 1.5 feet extra wire for service loop at both ends of the cables. 32
B2. Installation procedures X-ray equipment should only be installed by qualified personnel following the instructions in this manual and local code requirements. CAUTION! First of all, make sure the supply voltage corresponds to that indicated on the X-ray tubehead nameplate. Most domestic installations are for 115 volt operation. Turn off all power sources for the x-ray equipment. B2.1. Installing the X-ray equipment Determine if masonry or dry wall construction will be utilized. Locate vertical studs or structural members in the wall before mounting the pivot support assembly and articulating arm and control unit. Determine if electrical power supply wires will be internal to the wall or surface mounted. Use appropriate sized wall plugs, through bolts or expansion bolts to support the system. Prepare the power source and disconnect switch before mounting the system. B2.1.1. Wall Mount Pivot Assembly or optional wall mount plate Extension arm mounting plate First, determine if the wall mount pivot assembly will be mounted directly on the wall or if site conditions require the optional wall mount plate. This will be determined by the existing wall construction and load bearing ability. The wall mount plate spreads the load over a larger area and is recommended for dry wall/stud construction sites. The articulated arm Pivot Support Assembly must be mounted according to the type of wall (see diagram in section B1.3.). Locate the best position for the X-ray equipment by referring to the installation PLAN (Drawing no. 853-000002-1). Mount to the wall. X-Mind Digital timer mounting plate Place the X-Mind mounting plate where desired. If the control unit is to be placed near the X-ray equipment, refer to the measurements given in the installation plan. If, on the other hand, the control unit is to be installed a certain distance away from the tubehead(s) (e.g. in the corridor), 39 ft/12m long (max) electrical wiring must be provided (refer to the installation plan). In this case, the bottom part of the controller must be no lower than 4.6 ft/1.4m (approx). Having checked that the mounting plate is hori- zontal and at the correct height, make three marks on the wall, drill holes and insert the anchor bolts which best suit the wall. Pass the tubehead supply power cable through the mounting plate, then fix the latter to the wall having made sure it is horizontal. X-Mind Mounting Plate 33 Wall mount pivot assembly Pass the main power supply cable through the access hole in the mounting plate, then fix the latter to the wall by tightening the upper and lower anchor bolts. Do not connect electrical power supply at this time. (Refer to B2.2.1) B2.1.2. Extension arm Determine if the system is to be a single or dual tubehead installation. 1. Single Head Configuration The wall mounted extension arm pivot assembly comes pre-lubricated with Molykote D grease. Fit the pin into the hole of the mounting plate by lowering it down. Micro switches will not be used for single head installations. Make sure a jumper is connected between positions 8&9 on X-Mind controller terminal strip M1 (as detailed in section B2.2.2.) Use a spirit level to make sure the extension arm is slightly tilted upwards (approx. 1∞). If necessary, shim the plate (b), near the lower anchor bolts (c), tighten the latter. Finally, fully tighten the anchor bolts. Extension Arm 34 B2.1.3. Double-jointed pantograph arm WARNING! IMPORTANT! The two main parts of the pantograph arm are held together with a tie band. The band MUST NOT BE REMOVED until the two ends of the arm are fixed to the wall extension arm (already secured) and to the Xray tube head. If the tie-band comes loose before the arm has been fixed in place, the abrupt spring-back movement may damage the arm itself and above all may injure the installer. Due to its preloaded spring, the double jointed panto- graph arm cannot be used unless the related extension arm and tubehead are in place. The pivot bushing in the double-jointed panto- graph arm is lubricated. Using the cloth tape provided, attach the X-ray tubehead power cable which comes out of the pantograph arm, to the tape and pull the wire through the hole in the extension arm until it goes out at the opposite end. Lower the pantograph arm into the extension arm bushing. Take up the slack on the power cable by pulling gently at the other end of the extension arm. Attach power cable from the pantograph arm to the cloth tape at this end of the extension arm. Gently pull on the tape (after attaching the power cord to the other end) until the power cord comes out this end of the extension arm. 35 B2.1.4. Tubehead Installing the tubehead: Make sure the tie-band of the arm is tight. Remove the tubehead from the pack- age, lubricate the pin and the bushing with MOLIKOTE (D) graphite-based grease. Do not lubricate the brass electrical contact as shown. After removing the collar screw, pull the collar up to this position and secure temporarily by putting the collar screw back in half way. Next, remove the grounding clip using a phillips screw- driver. Push the tubehead all the way up into the bushing until the slot in the tubehead lines up with the slot in the bushing. Insert the locking key into place and slowly release the weight on the tubehead until it is secure in place. Replace the grounding clip and screw. Remove the collar screw and lower the collar back down over the locking key and grounding clip. Replace the collar screw to lock the collar in place. Move the tubehead several times on the horizontal plane in order to evenly spread out the grease and balance the load. Removing the tubehead Repeat the above operations in reverse order. B2.1.5. Adjusting the arm lock Adjust the lock to prevent the arm from unnecessary horizontal motion. Loosen or tighten the friction screw in the hole in the end of the extension until the required friction is obtained (use a 3 mm Allen wrench). Once the adjustment has been made, replace the end cap onto the extension and secure with the phillips screw provided. Locking Key for tubehead Collar screw 36 B2.1.6 Balancing the double-jointed pantograph arm If the double-jointed pantograph arm ineeds balancing, carry out the following adjustments: Adjusting the first (vertical) arm (Friction adjustment only) Raise the second pantograph arm to a horizontal position. Pull the bellows on the center joint towards the tubehead in order to uncover the joint itself. Using the 10mm and 13mm open end wrenches, hold the 10mm nut in place while turning the 13mm flat on the bolt in 1/ 4 turn increments to either increase or decrease friction on the arm. Once the arm has been correctly adjusted, put the bellows back into place. Adjusting the second (horizontal) arm (Friction and Spring Tension) After raising the arm to the horizontal position, friction adjustments may be made in exactly the same way as previously explaned above. If the spring needs to be tightened or loosened, insert an 8mm allen wrench into the end of the lead screw (as indicated by illustration B at the left) and turn clockwise to tighten or counter-clock- wise to loosen. Once the arm has been correctly balanced, pull the bellows back over the collar. 37 B2.2. Electrical system - Refer to wiring diagrams on pages 38 - 40. B2.2.1. Electrical hook-up of wall mount pivot assembly Connect the wires coming from the pantograph arm and the tubehead supply power cable coming from the control unit (through the access hole)to the ìMî terminals on the terminal block: L - BLACK OR BROWN supply wire N - WHITE OR BLUE neutral wire YELLOW/GREEN ground wire Secure the cables to the related fasteners by using the buckle clips. WARNING If the Yellow/Green ground wire to the tubehead exceeds 14 AWG (6), use an eyelet terminal to fix it to the ground screw of the wall-mount plate. For single tubehead installations, the micro switches will not be used. . Connect the ground leads to the ground terminals as indicated here. WARNING To ensure proper electrical connec- tions, follow the wiring diagram.

Be advised that a 220/230 Volt board is physically different than a 110/115 Volt board. Simply chang- ing the jumper settings does not actually change the board from one voltage rating to the other. 40 B2.2.5. Conditioning the X-ray tube Once installation has been completed, the X-ray tube is to be conditioned so as to eliminate any impurities which may have built up on the anode during storage or shipment. To do this, proceed as follows: Set a time of 0.02 s. Allow the tube to emit radiation at least 1 5 times. Set a time of 1 s. Allow the tube to emit radiation and make sure the control unit does not indicate the presence of faults. WARNING Whenever making an x-ray exposure, use extreme caution. Keep as far as possible from the source of radiation. Stay opposite the direction in which the X-rays are emitted. Use protective apron or shields as necessary. B2.2.6. Checking the power supply to the control unit Take readings with an AC voltmeter (maxi- mum end-of-scale value: 200 Vac) to make sure the supply is as specified for the equipment. Connect the voltmeter to terminals L and N on the terminal block M2 of the control unit board. Turn on the control unit and check the voltage readings on the voltmeter (voltage with no load applied). Start an occlusal radiograph by turning the selector to position 9 and choose a large body size. Move as far away as possible from the area where the X-rays are to be emitted. Perform a radiograph then while the Xrays are being emitted check the voltage indicated on the voltmeter (voltage with load applied). The result of the following equation [(V without load - V with load): V with load] x 100 must not exceed 3%. If this is not the case, check the electrical supply. 41 B3. Preventive maintenance B3.1. Checks Dent-X recommends that the following maintenance procedures be carried out periodically. It is good practice to perform this check-out procedure when the equipment is installed and then once every year after. IMPORTANT CAUTION: TO BE PERFORMED ONLY BY A QUALIFIED SERVICE TECHNICIAN Should any trouble be found when these checks are made, consult the ìCorrective maintenanceî chapter contained herein or contact Dent-X technical support. In the meantime do not allow use of the equipment. B3.1.1. X-ray tubehead Make sure the nameplate is legible Check that the collimator firmly secured in place. B3.1.2. Attaching the X-ray tubehead Make sure the tubehead moves smoothly. Should this not be the case remove the tubehead then check and clean the internal parts.

Mobile Stand P/N 9992700110 Assembly and Maintenance Instructions The AFP Image-Vet70Plus Mobile Stand is constructed of steel and coated with abrasion resistant epoxy paint. It consists of a rolling base assembly and vertical support column. Four wheels attached to the base allow free movement of the system between locations. The folding arm with tubehead and x-mind timer are mounted at the top of the vertical support. Screws, located in the top of the support act as stops to limit the range of movement of the folding arm to an area extending over the base legs. This lends stability to the unit. CAUTION: Never attempt to operate the unit with the folding arm extended in the direction opposite the legs. The vertical post is bolted through the base assembly and is positioned by a roll pin inserted between the base and the vertical support. A power cable and handle are provided. Assembly Base Refer to Figure 1 for the following: 1) Using a flat surface, lay out the base legs (Items 1 and 2) as shown with the holes for the castors facing up and the counter-bored holes for the bolts facing outward. NOTE: One left handed and one right handed leg. 2) Place the support plate (Item 3) between the two base legs as shown. NOTE: The top side with two holes about center should face down. 3) Insert the four (4) bolts and washers (Items 4 and 5) through the base leg holes and screw into the corresponding holes in the support plate using the Allen key provided. Make sure they are tightened firmly. 4) Identify two locking castors and two plain castors. One of each is used per leg. Screw in each of the four castors provided into the holes in each of the legs (Items 1 & 2). Alternate construction may have smooth mounting stems on the castors that fit into a matching plastic guide. 5) Turn over assembly so the castors are on the floor. Description 1 2 3 4 56 Figure 1 51 Assembly (Contíd) Main Unit Refer to Figure 2 for the following: Using the Allen key provided, fasten the vertical support column (6) to the base assembly with the bolt (9) and lock-washer (10) provided, making sure that the locator roll pin (11) is inserted into both the base and the support column. Insert the cable (Z) from the folding arm through the bushing (M) at the top of the vertical support column and out through hole (L). TIP - Fold the cable over first, then insert the folded part down through the bushing to lend rigidity. Make sure that both the pin (P) of the folding arm and bushing (M) of the vertical support are clean. Apply a small amount of graphite based grease to the pin. Gently lower the pin and folding arm down into the bushing (M). Make sure that it rotates easily. CAUTION: Never operate the unit with the folding arm extended in the direction opposite the legs. Fasten the back cover of the timer housing to the mounting plate (N) and the vertical post (6) with the screws, flat washers, lock washers and nuts provided. No nut is needed for the third screw at the top of the housing since the column is pre-threaded. Carry out the electrical connections in accordance with the instructions in sections B1.4 (Electrical Requirements), B2.1.1. (Timer Mounting), and B2.2.2 (Wiring the control - Single Tubehead) in this manual. Fasten the timer cover. Attach the handle (5) with 2 allen cap-head bolts (4). Refer to section B2.1.4. for attaching the tubehead. To remove the tubehead, return the positioning arm to the upper position, raise the plastic cover and remove the retainer key (see Figure 3). Then slide the tubehead out of the connector. Warning: To avoid possible injury or sudden movement of the positioning arm, always remove the tubehead while the forearm section of the positioning arm is in the horizontal position. Refer to Sections B2.1.3. and B2.1.6. in this manual Cleaning and Maintenance For external cleaning use a soft cloth with warm water and mile soap. Once a year, lubricate pin (P) and bushing (M) in the following way: 1) Switch off the power supply. 2) Unplug the cable (G) from the wall outlet. 3) Remove the Tubehead. 4) Raise the folding arm just enough to expose the pin and bushing. Have a second person hold the arm for you while you perform the next step. 5) Remove old grease and dirt from the pin and bushing with a soft cloth and re-lubricate with MOLIKOTE D or equivalent. Lower the arm back into the bushing. 6) Check the wheels and clean if necessary in order to insure that the unit rolls smoothly. 7) Check the wheel locks. 52 M 13 P Z 1 2 3 N 4 5 L 12 3 6 H 7 8 9 10 11 1 G 14 15 #7 INCLU DES * I TEM S 17 16 18 19 * * * * * Vertical Support 45.7" X 6.3" X 3.6" Gross Weight 15.5 lbs Net Weight 11 lbs Horizontal Support 33.1" X 29.5" X 3.2" Gross Weight 62 lbs Net Weight 59.5 lbs 47.3" 31.5" 30" Figure 2 Figure 3 Retainer Key for attaching the tubehead to the folding arm. 48.3 ositioned by a roll pin inserted between the base and the vertical support.
