tube head molex plugs together
and fit them into the slot in the
scissor arm and replace side covers
7- Insert the scissor arm “c” clip

14. BALANCING THE SCISSOR ARM
The scissor arm must be adjusted only AFTER the tubehead is assembled
To prevent damages to the internal mechanism while performing adjustment and the balancing
tests, the adjustment key must not be left in place. These adjustments are necessary to ensure
proper balance of the tube head and scissor arm. It may be necessary over time to perform
these adjustments if the tube head does not stay in place when moved.

15. 1- Remove both tube end side covers from the scissor arm by first loosening the side screws
2- Using a phillips screwdriver or other such tip push on the unlocking tab to release the side covers
NOTE: Failure to do this will result in breakage of the side covers!!!
4- Remove both elbow
side covers by removing
the relevant screws
This now exposes the screw in the scissor arm that’s used to tighten the spring for balancing the tube head and scissor arm

16. To reach the adjustment screw X, the arm A must be put in vertical position.
To reach the adjustment screw Y, the arm B must be put in horizontal position.
The adjustment key provided can be inserted only under the above conditions.

17. BALANCING THE ARM A

20. Insert the plastic exterior plate C between the scissor arm plastic housing and metal frame
Align the cover D to slide in front of the plate C; then position them and check that everything is locked into place then replace screw and cap D C

21. BASIC START UP PROCEDURE

22. Make sure the green power and the key switch are turned to “0”
Attach the main power cord to the wall mains.
Switch main green power switch on top of timer to “I” (on).
Turn key switch to “I”
Timer will now beep for 1 second displaying a time* in
the LED screen
If no error codes are present the system is ready for use
* The exposure time and parameters which appear on the display are the last that were set before the timer was turned off.
If the timer remains inactive for a few minutes, it switches to the stand-by mode
Press any key on the control panel to restore it to the operative mode.

23. GETTING READY FOR AN EXPOSURE

24. Before making an exposure check that the control panel parameters
(from Step 1 to Step 8) are suitable for the
radiographic exam.
Step 1- The led of the desired tubehead should be lit
Step 2- The led of the cone length in use should be lit
Step 3- The led of the selected tubehead should be lit
Step 4- The led of the desired radiographic voltage should be lit (DC only)
Step 5- The led of the desired radiographic current should be lit (DC only)
Step 6- The led of the desired type of patient should be lit
Step 7- The led of the desired film speed (or digital led if using sensors) should be lit or
Step 8- The led of the selected teeth should be lit

25. FINAL SETTINGS
Follow the standard intra-oral procedures positioning the patient.
Position either the film or the digital sensor depending on the technique to be used.
Follow the standard intra-oral procedures positioning the cone.
Before proceeding with the exposure check the selected time on the display.

26. Taking the exposure
1. Remove the firing keypad from the timer and extend out to keep a safety distance of a least 6 feet from the tubehead.
2. Advise the patient to remain still
3. On the firing keypad press the yellow button and keep it pressed until the acoustic signal (beep) stops and the yellow led indicator turns off.
Notes:
If the exposure key is released early, the exposure is immediately interrupted and the E12 error message appears on the display.
At the end of the exposure the green PAUSE led on the timer will intermittently light…This time is necessary to allow thex-ray tube to cool down.
The display indicates the actual exposure time

47. INTERNAL SETTINGS

48. Shown in the next section of slides is how to set the internal dip switches for using an AC tube head with an 8 and 12 inch cone with no external firing button. This is a straight forward example and can be applied to either an AC or DC tube head or a combination of heads and cones.

49. Once again in the bottom picture switch 1 & 2 work as a pair
Once again in the bottom picture switch 1 & 2 work as a pair. Switch 1 is on – this selects tube head #1, switch 2 is off - this selects an AC tube head…(Again for clarity, if it were a DC head it would be on).
Switch 3 & 4 also work as a pair for the second tube head and since there is none being used switch 3 is off and switch 4 then has no function.
Switch 5 is off - this de-selects a remote firing switch (if one is not used).
Switch 6 is off - this selects an 8 inch cone…(Again if a 12 inch cone is used it would be on.
Again, switches 7 & 8 are always left off.
As can be seen in the top picture switch 1 & 2 work as a pair. Switch 1 is on – this selects tube head #1, switch 2 is off - this selects an AC tube head…(For clarity, if it were a DC head it would be on).
Switch 3 & 4 also work as a pair for the second tube head and since there is none being used switch 3 is off and switch 4 then has no function.
Switch 5 is off - this de-selects a remote firing switch (if one is not used).
Switch 6 is on - this selects a 12 inch cone…(Again if an 8 inch cone is used it would be off.
Switches 7 & 8 are always left off. ,

52. This section provides instructions for some basic troubleshooting if an error code is shown. This information is provided to you as an “extra” should you need/want to know basic troubleshooting especially if an emergency “quick fix” situation should arise

53. If an error is detected when the system is turned on, the anomaly is indicated as follows:
- A beeping sound for several seconds
- The MALFUNCTIONING INDICATOR LED on timer will light briefly
- The error code (Exx) appears on the display
- All control panel functions are inhibited…In this case turn off the timer and then turn it back on.

54. In the event the generator experiences an error during use a resulting code will show in the display in the format Exx where xx will be the error code number. This error code will only show for 3 seconds and then will change to ERR.
Normally when the user experiences an error code they should first record the error code then contact their dealer or Acteon for tech support and provide the error code to them.

55. DESCRIPTION OF COMMON ERROR CODES

56. * Timer must be replaced
1) Switch On the XGenus system (Timer) : green light is On and the screen display shows a value of time
If not :
A. Check the security key (turned to 1 « ON » and not to 0 « OFF »)
B. Main fuses burnt on the Timer board (Timer must be opened to replace them)
C. Out of order display board (nothing shown on screen display, but other functions are ok) *
D. Out of order Timer board (DIP switch on the replacement Timer board must be set) *
2) E00 and E01
A. Wrong tube head selected on the keyboard (if both are enabled on DIP switch setting)
B. Tube head fuses burnt on XRay 1 and/or XRay 2 (Timer must be opened to replace them)
C. Short-circuited or cut arm cable (inside the arm)  Refer to X-RAY Product Specialist
D. Internal tube head wiring insulation defective  Refer to X-RAY Product Specialist
3) E X-Ray button already pressed by the user or is jammed « On » when Timer is turned On
4) E12 ______Exposure prematurely interrupted (Do not realese the trigger button until after the yellow light turns off on the
remote trigger)
5) E Ask technician to check main line voltage - may be too low or too high
6) E DC only: do a recalibration. If this does not correct error elevate to higher level support.
* Timer must be replaced

57. TUBE HEAD CALIBRATION
In many circumstances on a DC system a simple calibration may correct many error codes. Please look at the next slide explaining how to perform this calibration

58. 1- Turn off the timer with the green power switch
Perform this for the following error codes on a DC system only!!:
E30
E32
E33
E41
E42
E43
E44
E45
E46
E47
E48
If no success refer to higher level support.
Caution: During this operation there is X-RAY output. It is mandatory to observe all the safety measures relevant to radio protection
1- Turn off the timer with the green power switch
2- Turn the timer on again while holding the mA selection key
3- The LED will display “TUBE”
4- Select the tube head to be calibrated with the tube head selection key
5- Take the exposure until the beep signal stops
6- Once the exposure is finished and there is no error code the calibration is finished
7- Turn the generator off and back on again and then take an exposure to verify the unit is ok

59. LINE VOLTAGE CHECK
The next slide discusses how to check the generator via the LED display for any line voltages that may be out of tolerance for this system that would result in a corresponding error code

60. This function can be used to see whether the incoming line voltages are adequate or ever exceeded or went below recommended values.
To be used when the below error codes are present:
E07 : nominal value -5% +10% (AC) or ±15% (DC)
E44 : DC only
E45 : DC only
E46 : DC only
E48 : DC only
If the values are outside of -5% +10% (AC) or ±15% (DC) of the nominal line voltage an electrician is needed to check the office and/or building wiring.
If the values are within -5% +10% (AC) or ±15% (DC) of the nominal line voltage pass onto higher level support.

61. With X-GENUS® AC/DC radiographic system it is possible to look at the nominal line voltage, actual line voltage, maximum line voltage detected , minimum line voltage detected and software version of the Timer.
To access the parameters:
Press simultaneously and keep pressed the following keys:
MAXILLA MOLAR (2)
MANDIBULARY MOLAR (31)
Then:

62. Then press: RADIOGRAPHIC SYSTEM NOMINAL VOLTAGE LINE VOLTAGE
Press and hold both buttons shown simultaneously then while holding these buttons in press each button shown below to view the parameters listed in the LED screen on timer
Then press:

63. If any of the above troubleshooting does not solve the issue then the doctor should be directed to an X-RAY Product Specialist for further support.

64. NOTE:
One frequent question you may encounter in a DeGotzen in-service is: “What is the difference between an AC and DC X-RAY generator?” Please read the below paragraphs to help you understand the difference and therefore better educate the prospective buyer
The most economical way to produce x-rays is to use the alternating current that comes from the power company to power the x-ray head. This alternating electric current changes direction in the wires sixty times each second. It also increases and decreases in intensity one hundred and twenty times per second. The effect of using this current is to produce x-rays that turn on and off sixty times each second. Further, the x-rays that are produced each begin too weak to use, then grow to proper strength, then decrease again to being too weak. The design of the AC x-ray calls for filters of aluminum to eliminate the x-rays that are too weak to use. This ultimately leaves sixty pulses of x-ray each some what shorter in intensity than the next one each second. The DC x-ray machine uses direct electric current to power the x-ray head. Direct current does not change direction nor does it change intensity. Direct current is a steady supply of power and consequently the x-rays that are produced are smooth and consistent. This smoothness of the DC x-ray machine produces a better effect on the digital sensors than an AC x-ray generator.
“Single pulse” radiation
(AC or low frequency – 60 Hz)
“Multi-pulse” radiation
(DC or high frequency – 200 kHz)

65. THE END
