Maintenance Instructions CDR PanElite |
|
1 General
To stay in compliance with the DHHS requirements the CDR PanElite must be maintained annually.
It is the responsibility of the user to insure that the equipment is maintained with the manufacturer's recommended Maintenance Instructions to insure compliance with the Federal Performance Standard.
The manufacturer and the assembler/installer are relieved from responsibility in those cases where the user fails to have the manufacturer's recommended maintenance performed.
The actual maintenance inspection and consequent service must be accomplished by a trained serviceman. Neither the inspection nor service is part of the equipment warranty.
Technical instructions required
Operating Instructions
Service Manual
Instruments and adjustment tools required
All measuring devices must be suitable for measurements on the mains potential.
This includes the pulse counter.
This means: A voltage of 1000 V between a connection and ground must be possible.
1.Digital multimeter Fluke 87 III or equivalent.
Accuracy:
DC voltage ± 0.1 % of reading plus 0.02% of range DC current ± 0.4 % of reading plus 0.1% of range.
2.Electromechanical pulse counter, model KESSLER ELLIS KT 203 ±1 pulse, or equivalent..
3.Adjustment set with alignment tool for X-ray beam , test block and needle phantom delivered with the unit, (customer's property).
ATTENTION
RADIATION!
Observe the radiation protection guide lines as outlined in the Operating Instructions manual.
X-radiation is emitted as long as the exposure switch is depressed.
The X-ray indicator must light up on the Control Pad during radiation. An acoustic signal should also be heard.
61 88 085 D3352 D3352.103.02.01.02
Power Supply Adequacy
To assure that the CDR PanElite system performance is in accordance with Schick specifications, an adequate power supply for permanent installation is essential.
The Federal Performance Standard for diagnostic X-ray units, code of Federal Regulations, Title 21 CFR, Subchapter J, mandates an adequate power supply.
Duty Cycle
Between exposures a minimum cool-off time is maintained (automatic exposure blockage, see Operating Instructions manual).
Operating Instructions
During measurements and adjustments it is necessary to energize or de-energize the unit. For all operating steps please refer to the Operating Instructions manual.
CAUTION with PC Boards!
All PC boards are fitted with electronic components sensitive to electrostatic discharge (ESD). Electrostatic charges are unavoidable due to friction caused by clothing, carpeting etc.
ATTENTION
To prevent damage of electronic chips do not touch components.
Always handle circuit boards by their edges.
ATTENTION
Electrical Shock Hazard!
Always turn unit OFF before connecting and disconnecting the test leads to the test points

•Unit ON LED:
Press the main switch to the ”I” position to turn unit ON. Power ON tests to take about 1 minute.
The ”Unit ON LED” in the upper right corner of the user interface will then be lit".
•Testing the keys and the functions on the user interface.
–When the height is adjusted, an acoustic signal is active.
–If the forehead support functions correctly, the max. holding torque is still present.
–If remote is installed, test the remote keys and verify proper operation of the display.
–The exposure switch must not be defective or broken.

•Take an exposure:
–X-ray head must be in the initial position (If not, press return key R).
–Make sure that CDR PanElite Service program is ready to take an image.
For more details and possible error messages see Operating Instructions.
–Set the P1 exposure program using the menu keys.
–Select 68kV/8mA using submenu keys.
CAUTION RADIATION
–Press and hold the exposure switch until the exposure terminates automatically.
–The exposure ends when the rotation and radiation switch off automatically.
–The radiation indication must light up during the exposure period.
–Simultaneously an audible beep must sound at the unit.
•Interrupt an exposure – deadman feature:
–Observe a cool-off time of max. 5 mins. between exposures (automatic exposure blockage).
–Setting same as above.
CAUTION RADIATION
–Press the exposure switch until X-ray lights up and subsequently release – the exposure must terminate immediately. The radiation indicator lights up.
ATTENTION
Defective light indicators constitute a safety hazard to the patient as well as to the operator.

5kV – verification, kV ramp during panoramic exposure
1. |
WARNING
The electronics of the X-ray tube assembly are always connected to line voltage.
Always switch the X-ray unit off and wait until V203 is no longer illuminated before contacting the test leads.
WARNING
The test leads and measuring instruments used must have a dielectric strength of at least 1000V!
Be sure to use a battery-powered measuring instrument with shock-hazard-protected sockets.
Use only test leads with shock protection.
ATTENTION
The X-ray tube assembly moves during the measurement. Therefore, be sure to use test leads of sufficient length and place the measuring instrument in a location where it is firmly seated so that it doesn’t fall down during rotation.

i NOTE |
Measurements: |
62kV correspond to 3.1V, tolerance +/-10% |
i NOTE
During exposure the kV is increased in the central region depending on kV/mA selected by up to 10%. This increase can be measured in VDC.
1.Remove cover (for details see Service Manual).
2.Remove the four screws A and remove cover plate B of the electronics box.

6 Tube Current Verification
WARNING
The electronics of the X-ray tube assembly are always connected to line voltage.
Always switch the X-ray unit off and wait until V203 is no longer illuminated before contacting the test leads.
WARNING
The test leads and measuring instruments used must have a dielectric strength of at least 1000V!
Be sure to use a battery-powered measuring instrument with shock-hazard-protected sockets.
Use only test leads with shock protection.
WARNING
Be sure to switch the X-ray unit off before removing the jumper for the mA measuring jack.

1.Remove shunt jumper A from MA+/MA – test points on PC board DX6. Connect digital multimeter to VDC and select range 20 mVDC.
2.Reattach cover C and tighten screw D securely.
3.Switch unit ON n.
Wait 1 min. for self-adjustment of the unit.
Press key R oto return X-ray tube head into the initial position.
4.Select 66kV/8mA. Make sure that CDR PanElite Service program is ready to take an image.
5.If P1 program and 66kV/8mA are selected . The unit must be ready for radiation.
Measurement:
CAUTION RADIATION
– Press and hold the exposure switch until meter reading is obtained.
The multimeter shall indicate 8mV ±1.6mV. Record reading.
i NOTE
Readings: 1mV corresponds to a tube current of 1mA, tolerance +/-20%.
i NOTE
If specified values cannot be obtained, see Service Manual, chapter ”Tube Current Verification”.
