5GENERAL FEATURES
5.1 Fault protection
In order to protect the x-ray tube high voltage generator circuitry as well as the tube head and the
x-ray tube itself against various kinds of overload conditions certain actions are taken, explained
in the following.
Amplifier section voltage check
The generator operational amplifiers have operating voltages of about +14V and -14V. If one of
them is below about 12.5V the generator is disabled with corresponding error indication in order
to prevent erroneous operation.
Tube head temperature
The tube head temperature is measured continuously and exposures are not allowed if the tem-
perature rises to 60°C or above. Should the temperature sensor be inoperative (open circuit or
short circuit) the exposures are as well not allowed.
Earthing check
The temperature measurement is done by using the tube head protective earth wire as signal
return to the generator processor board. This will create a less than 2 mA current to the wire and
allows to check that both the tube head and the electronics ground are connected to the protec-
tive earth. If not, a temperature sensor open error will be indicated and generator is disabled.
Feedback check
Before the exposure is started both the kV- and mA-feedback inputs are measured. If the cables
are not connected properly or for some other reason the results are not normal the system does
not allow exposures and an error is indicated.
Focal spot temperature
During each exposure the x-ray tube focal spot is strongly heated up. Therefore a certain time
must be allowed between exposures in order to allow the heat to spread in the tube head. The
cooling characteristics depend on the tube type and therefore the cooling times are calculated
using different formulas based on the tube manufacturer data. Before each exposure the tube
thermal conditions are checked and based on the requested exposure parameters (kV, mA and
time) it is calculated whether an exposure can be started immediately or only after a waiting
period, that is visible to the user.
Pre-heating and filament check
When the kilovolts are raised across the x-ray tube the tube filament must be in such a tempera-
ture which will generate the desired current through the tube. To achieve this the filament must
be pre-heated. During this two second long pre-heat period the filament voltage is adjusted by
the microprocessor to match the mA-value requested. (The actual filament voltages have been
measured by the system at each mA-value during so called ‘filament initializing’ procedure that
has to be run through once when the system is first taken into use. If this is not done, normal
exposures will not be allowed by the system.) At the end of the pre-heat period the filament volt-
age is checked. If it differs more than 0.1 volts from the desired one the exposure is not started
and an error indication is given. The filament power supply has a current limit of about 4 A and it
is fused with a 3.15 A fuse. The two second time is short enough not to create overheating of any
kind or blow the fuse even if the filament was shorted. If the current limit is defective and the
adjustment circuits are inoperative the fuse will blow.

Chapter A - GENERAL & TECHNICAL DATA
Planmeca Proline CC panoramic x-ray A-7
Technical Manual
Starting exposure
If the pre-heat phase was passed without error the high voltage generator is enabled. In normal
conditions the kilovolts will rise within about 8 ms and the mA-value rises simultaneously.
Depending on the component tolerances the voltage rise will start from 5 to 15 ms after the ena-
ble first was active. After 40 ms from the enabling both the tube voltage and current are moni-
tored. If the voltage has not reached the desired value within 6 kV the generator will be stopped
with an error indication ‘kilovolts do not rise’. Correspondingly, if the current is not within 1 mA the
generator is stopped with indication ‘mA does not rise’.
Generator current limit
The high voltage generator has a current limit circuit built in the hybrid IC10. It will limit the cur-
rent of the end stage to about 13 A cycle by cycle basis. The normal operating current at maxi-
mum exposure parameters is about 7.5 A but when the generator is started the charging of the
cascade capacitors need some extra current. In the case that the tube head is short circuiting
momentarily or continuously this circuit will limit the current through the end stage FET’s Q6 -
Q10 to about 13 A. The microprocessor monitors the tube head parameters after 40 ms from the
beginning of an exposure and during the exposure with a time interval of 2.5 ms. If the end stage
was operating at full 13 A current the FET’s would be overheated within few seconds but the
microprocessor detects the problem and stops the generator well before anything will break
down.
Exposure parameter check
During the exposure the microprocessor monitors all the parameters and adjusts them. If for
some reason the kV-value drops more than 6 kV from the nominal, the exposure is stopped with
error indication ‘kV does not rise’. Also, if the mA-value differs more than 1 mA from the nominal
the exposure is stopped with an error indication ‘mA does not rise’ or ‘filament control inopera-
tive’ when overcurrent is detected.
Tube arching
If during the exposure a sudden drop of kV is detected the generator is stopped with an error indi-
cation ‘Sudden drop of kV detected’. If the x-ray tube is arching this is normally the procedure.
However, it might happen that the kV drops down and rises back up between the 2.5 ms micro-
processor measurement interval. In this case the generator is stopped by overvoltage and error
indication “overvoltage in tube head” will be displayed.
Overvoltage detection
The generator has a separate overvoltage detection circuitry that will stop the generator if the
tube head voltage exceeds about 92 kV. The microprocessor is monitoring and adjusting the volt-
age, but this circuit is a separate hardware comparator, working independently from the micro-
processor.
Generator time out
The longest panoramic exposure takes a little above 18 seconds. The microprocessor has an
independent timer routine to check the exposure time. If it exceeds 22 seconds the generator is
stopped with time out error indication. In service mode this timer will stop exposure without error
indication if the exposure switch is continuously pressed. To be able to operate the equipment’s
two microprocessors must have their clock frequencies synchronized to each other better than
1%. This guarantees that the timer function will be accurate enough.

Chapter A - GENERAL & TECHNICAL DATA
A-8 Planmeca Proline CC panoramic x-ray Technical Manual
5.2 Maximum exposure rate
The maximum operating frequency is limited due to the heating of the X-ray tube. There are two
different limiting factors:
First is the time that has to be waited between exposures in order to allow the heat to spread out
from the tube anode into the oil of the tube head. If this was not done, the tube anode can start to
melt during the next exposure.
The second factor is the maximum allowed temperature of the tube head itself. It shall not
exceed 60 °C because of the thermal expansion of the oil and also because of the thermal limits
of the components inside.
In Planmeca Proline CC Panoramic X-ray unit, there is an automatic function implemented in the
microprocessor to calculate the cooling periods between the exposures. Depending on the type
of the X-ray tube and the exposure parameters used the wait time will be calculated and shown
in the clock display. This function protects the X-ray tube not allowing an exposure to be taken
while the wait time is on. The maximal wait time that can be generated by this function is about 1
min. 40 sec., so it does not remarkably reduce the actual exposure rate and still makes it impos-
sible to destroy the X-ray tube by misuse.
In order to control the tube head temperature the microprocessor is measuring it all the time. If it
raises above 40 °C the fan is started and if it raises above 60 °C the temperature is displayed in
the clock display and further exposures are prevented. The system is not able to calculate the
actual waiting time in this case because that depends mainly on the ambient parameters (room
temperature, air flow etc.), but the temperature is displayed to allow the user to estimate the wait-
ing time. (It will normally be about 10 min.) It is very important that the temperature measurement
is in order. Therefore it is checked all the time and an error message is generated, preventing fur-
ther exposures, if the measurement circuit is either short circuiting or an open circuit.

2.6 Test mode
The test mode enables the X-ray to be operated without radiation being generated. Press the
CTL-key and press any of the kV selection and mA selection keys. The kV and mA displays will
clear indicating that the X-ray tube has been switched off and that you have entered the test
mode.
Repeat the above procedure to exit the test mode and switch the radiation on again. The mA and
kV values will reappear on the display.
2.7 Parameter history display
The parameters of the 25 previously taken exposures are stored into the memory of the equip-
ment and can be examined or taken into use if desired. Pressing CTL and then the UP or DOWN
key activates this parameter history display mode showing the last taken exposure parameters.
In this mode the keys ready, up, down and CTL only are operative. Operating the other keys
does nothing. The functions of these keys are:
UP Find next parameters (newer one)
DOWN Find previous parameters (elder one)
READY Take the parameters shown into use and exit to normal
mode
CTL Exit to normal mode
All displayed parameters (but the time display) indicate the parameters selected during the spe-
cific exposure. If the exposure time display is blinking, it indicates that the taken exposure was a
cephalostatic one. Note that everything, including the special segment selections, sinus mode
etc. are stored into the memory and can be restored with ready key.
NOTE The cephalostatic exposures don’t store the layer position but the soft tissue wedge posi-
tion.
NOTE The height adjustment is not restored.
The time display indicates the used exposure mode, e.g. PAn, CEPH, P 30.
If less than 25 exposures have been taken the history does not go down to 25 but only to the
amount of exposures taken.
If the history parameters are not desired to be taken into use, there are two ways to exit this
mode without altering the currently selected parameters.
When the CTL- key is pressed the equipment returns to normal mode.
When ready is pressed while the running number 00 is displayed the currently selected parame-
ters are taken into use (no change).
Pressing ready changes the currently selected parameters to the ones that were displayed and
returns the equipment into normal mode.
