General information
ATTENTION !
Proper shielding of room and operator
position is essential.
Since these requirements vary from state
to state it is the assembler's/installer's
responsibility that all local radiation
safety requirements are met.

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.
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 sensi-
tive to electrostatic discharge (ESD). Electrostatic charges
are unavoidable due to friction caused by clothing, carpeting etc.
English
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).
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.
To prevent damage of electronic chips do not touch components.
Always handle circuit boards by their edges.
Electrical Shock Hazard!
Always turn unit OFF before connecting and disconnecting
the test leads to the test points

• Look for mechanical damage that may affect radiation
safety.
• Verify that all labels are affixed and legible.
Defaced labels must be replaced.
Order labels from Schick (address, see rear)
in writing stating:
• Customer Name
• Customer Address
All Model Numbers with Serial Numbers should be legible
on the unit for identification purposes. For serial numbers
see also Installation Report.

5 kV – verification, kV ramp during panoramic
exposure
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.
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.
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.
Measurements:
62kV correspond to 3.1V, tolerance +/-10%
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.
