5 GENERAL 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.

A-6 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter A - GENERAL & TECHNICAL DATA

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.

Technical Manual Planmeca Proline CC panoramic x-ray A-7

Chapter A - GENERAL & TECHNICAL DATA

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.

CTL

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.

Main display
The main display in the upper left corner normally displays the tube head temperature. However,
if the system has detected an error the main display indicates the error number occurred. The
error is cleared by pressing CTL-key and the temperature display reappears. Also, similarly to
the normal mode, if the tube head temperature exceeds 60 °C the temperature display blinks and
the exposures are not allowed and if it is not possible to make a new exposure due to the X - ray
tube cooling characteristics the blinking count down time is displayed.
When the CTL-key is pressed (the CTL key indicator light is on), the potentiometer signal of the
cephalostat soft tissue light is shown on the display.

3.4 Exposure counter display

CTL
Total exposure counter
OR
CTL
Panoramic exposure counter

OR
CTL Cephalometric exposure counter

In the service mode it is possible to verify the amount of exposures taken. There are three
counters in the system, one counting the normal panoramic exposures, one counting the cepha-
lostatic exposures and one counting every exposure (also the ones made in the service mode).
Exposures that caused an error and were interrupted are not counted. When one of the counters
is wanted to be seen, after the right key sequence the counter is displayed in the main display for
a few seconds after which the normal temperature display reappears. The key sequence always
needs to be started with the CTL-key to get the indicator light on and the second key determines,
which counter is displayed.
Because the main display has only four numbers on it and is therefore capable of showing counts
only up to 9999 a special method has been provided to be able to display counts up to 49 999.
The two dots between the numbers indicate the amount of 10 000 to be added to the displayed
number as follows:
Lower dot on Add 10 000
Upper dot also on Add 20 000
Lower dot blinking Add 30 000
Upper dot also blinking Add 40 000
When 50 000 exposures has been taken the counter is cleared to zero and starts to count the
next 50 000.

3.5 Error history display

CTL READY
PRET

In order to make the equipment failure analysis easier an error history display has been provided.
This error memory contains the 50 last errors occurred (not Er 00). The stack depth is not neces-
sarily 50, if less errors have occurred. In this case only the amount of errors that have happened
is displayed.
Press the CTL-key and the return key to enter this mode. The last error occurred (-01) is shown.
If no errors were memorized the displays appear blank. In this mode all the indicator lights are
undetermined and the numeric displays have a different function as is explained in the following:
PRIMARY SLOT DISPLAY Blinking E to indicate Error display mode
kV-DISPLAY Day of month when error occurred
mA-DISPLAY Month when error occurred
MAIN DISPLAY Hours and minutes when error occurred
EXPOSURE TIME DISPLAY Error code number that occurred
mm-DISPLAY Running number of this error in the stack (-01 - -50)
In this mode the keys READY, UP and DOWN only are operative. The functions of these keys
are:
UP Find next error (newer one, towards -01)
DOWN Find previous error (elder one, towards -50)
READY Exit to service mode

mm PRET

OR
CTL

hold for
4 seconds

The up/down motor first second speed can be adjusted individually to both directions to suit the
various needs of the equipment operators and to compensate for the individual frictions and
weight balances of the equipment.
Press the CTL and press and hold down the up key for 4 seconds to activate the adjustment
mode for up-direction (CTL and down key for down-direction). In this mode the keys ready, up,
down, mm- and mm+ only are operative. The functions of these keys are:
UP Move the equipment into direction up
DOWN Move the equipment into direction down
mm- Adjust the speed slower
mm+ Adjust the speed faster
READY Exit this mode and program the new speed into the memory
The main display indicates the direction to be adjusted and the relative percentage of the current
speed with an arrowhead pointing up or down and the speed (00-99). The speed indication is rel-
ative, 00 meaning the minimum and 99 the maximum possible slow adjustment speed. 00 is not
stop and 99 is about half of the maximum speed of the motor. The factory default is 55.
The adjustment is altered with the mm- and mm+ keys after which the speed can be checked by
moving the equipment with UP or DOWN keys. Note that the direction under modification never
accelerates to the full speed but continues at the slow speed to allow the proper verification of it.
The opposite direction operates normally.

NOTE In this mode the end limit sensors are not checked to the direction under modification.
This allows to get the Z-carriage easily in it’s normal operating range if it was for some
reason jammed outside the limit sensor and had lost the right position information. See
chapter UP/DOWN motor for information of the operating philosophy.

3.7 Exposure switch selection

CTL READY
PRET

The remote exposure switch type can be selected. The new type is equipped with a ready light
that will come on when the unit is correctly se up and ready to take an exposure.
Press the CTL-key and the READY key to select the desired exposure switch type. When the
switch type equipped with the ready light is selected, the ready light on the holder will come on. If
there is not a ready light on the holder, the exposure indicator light will come on to indicate that
the wrong type switch has been selected and you must select the other switch type. When the
switch type without the ready light is selected, the ready light on the holder is off and indicates
that the wrong type switch has been selected.

3.8 Panoramic/cephalostatic setup

CTL

The equipment software has been readily equipped with the functions needed for cephalostatic
operation. In the service mode it is determined whether the equipment is equipped with a cepha-
lostat. Of course the cephalostatic locking coils have to be added, the special cassette holder
assembled, adjustments made etc. to gain the cephalostatic operation. This chapter only
describes the keyboard operations needed when changing the equipment to a cephalostatic one.
Press the CTL-key and then press either the sec- or sec+ key to change the mode of operation.
The new state of operation is indicated for a few seconds in the main display, PA for panoramic
operation and CE for panoramic/cephalostatic one.

3.9 Tube type programming

CTL B D EXP

A P E hold until finished

hold for
4 seconds

A possibility has been provided to be able to use two different types of X-ray tube in the equip-
ment. The possible types are Comet XL-90-5°/0.6B and Toshiba D-052SB. The main difference
is the size of the focal spot of these tubes: 0.6 x 0.6 mm and 0.5 x 0.5 mm correspondingly.
Because the filament characteristics and the loading curves of the tubes are not the same, the
type of the X-ray tube in the tube head must be entered into the system to ensure proper opera-
tion. Also, if the Toshiba type is used the jumper J3 (see picture below) on the generator board
must be placed in position “T” and with Comet types in position “C”. Change fuse F7 to 4 A.
Press the CTL-key and press and hold the segment key A, B or C for 4 seconds, the tube fila-
ment definition will start. The display will now show Fd.
To prevent from accidental programming the segment key has to be held down for 4 seconds
before it operates.

CAUTION Always program the tube type into the system when the generator processor board or the
tube head is replaced. Even if the new tube type is the same than the previous one, the fil-
ament characteristics are not exactly the same and must be reprogrammed. Failing to do
this may damage the tube head.

Pressing down the exposure key after the tube type programming starts the generator with 70 kV
and 2 mA (the system adjusts for these values automatically). The system regulates the filament
voltage to get the 2 mA tube current accurate, changes to 3 mA and so on till all tube current val-
ues up to 12 mA have been adjusted. After the learning procedure the generator stops and the
tube type display stops blinking to indicate that the system is now ready for normal operation. If
the exposure switch is released before the procedure is complete (about 2 minutes), it will be
continued from that point on when the switch is operated again. If the power was switched off the
procedure starts from beginning. When the tube filament definition is done the exposure time dis-
play will indicate “C.6” for Comet 0.6 tube and “t.5” for Toshiba tube.

The error code is displayed on the main display. Press the CTL-key to clear the error from the
Er 12 display. Please refer to the section “Error history display” on page B-13 how to display the error
list. If you need further assistance with fault-finding, please refer to section “TROUBLESHOOT-
CTL ING” on page G-1.

3.1 Errors 00-07 (User related errors)

Er 00 Exposure switch was released too early during exposure

The exposure switch was released too early by the operator.
Exposure switch not making good contact or connecting cable broken.Try exposures in the serv-
ice mode while moving the cables.

Er 01 Line voltage drop detected

Equipment has been switched off and immediately on again which is detected as a short line volt-
age drop by the equipment. After switching off the equipment, about 5 seconds should be waited
before switching on.
Line voltage has dropped below - 10% from the nominal. This more often happens during the
exposure when the full 1.5 kW power is drawn and if the mains wiring is not properly done. Meas-
ure the line voltage when loaded.

Er 04 The cassette carriage not in ready position when the exposure switch was pressed.
The cassette carriage was not driven to the ready position before taking an exposure. Press the
ready key to move the cassette carriage and the rotating unit to the ready position and then take
an exposure.

Er 05 Wrong secondary slot

The wrong secondary slot was used. The wide secondary slot can not be used in the panoramic
mode. Select the narrow slot and take an exposure.

Er 06 Rotating unit not in the end sensor (in Transversal slicing system mode)
The rotating unit is not in the end sensor (Transversal slicing system mode). Drive the unit to the
end sensor with the special program keys and take an exposure.

Er 07 The rotating unit is not in the ready position

The rotating unit is not in the ready position. Check that the program selection is completed.
Press the ready key to move the rotating unit to the ready position and then take an exposure.

Er 08 The wrong type sensor head attached to the cephalostat

The wrong type sensor head (i.e. panoramic type) attached to the cephalostat. Remove the sen-
sor head from the quick connector of the cephalostat and attach the cephalometric sensor head
to the quick connector.

3.2 Errors 10-12 (recoverable errors)

Er 10 Overvoltage in tube head (tube arching)

An individual overvoltage detector circuit, located on the generator processor board stops the
generator when over 92 kV voltage is detected.
X-ray tube arching may trigger this circuit. This is the case when an audible ‘knock’ can be heard
from the tube head at the same time. It is quite normal that this happens every now and then and
causes no extra actions to be taken. If this continues to happen more frequently, tube head, gen-
erator processor or tube power generator is to be suspected in this order.
If this error indication appears after 1 second when the exposure switch was pressed (in the mid-
dle of the pre-heating) the generator is defective.

C-4 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter C - HELP & ERROR MESSAGES

Er 11 Sudden kilovolt drop detected (tube arching)

kV feedback cable making bad contact
Tube arching. This is the case when an audible ‘knock’ can be heard at the same time. Quite nor-
mal but if it starts to appear more frequently, the tube head is to be suspected.
Generator stops operating when the exposure is on. More likely the generator voltage drops and
the undervoltage detector operates. Bad wiring or poor connections. Check generator voltage
while operating.
Generator or tube head defective. If this is the case the next exposures give indication ‘kV does
not rise’.

Er 12 Tube filament initializing not done

When first taken into use after tube head or generator processor replacement the tube filament
pre-heating values must be initialized. In the service mode this will be automatically done when
exposure switch is continuously pressed till operation stops. If this is not done, an attempt to
make a normal exposure will give this error indication.

3.3 Error 15 (Transversal slicing system error)

ER15 Layer positioning motor not calibrated

If the layer positioning motor has not been calibrated or there has been a flat battery, the trans-
versal slicing mode can not be entered.
Calibrate the layer positioning motor according to the instructions given in section “Patient posi-
tioning mechanism adjustment” on page D-14 (film-based panoramic x-ray) or “Patient position-
ing mechanism adjustment” on page E-31 (Dimax digital system).

3.4 Errors 20-28 (time out errors)

Er 20 Tube power generator time out

There is an individual RC-timing circuit on the generator processor board that measures the
exposure time length. If it exceeds about 25 seconds the generator is stopped with this error indi-
cation.
Check in service mode the length of the exposure. If it is less than 22 sec. and this error comes
on, the RC-circuit is defective. Replace the generator processor board.

Er 21 Up / down motor time out

If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
If keyboard button was operated all the time the reason is either that the up/down motor cable is
broken (no movement or sound) or the carriage is jammed (humming sound 200 Hz can be
heard but no movement). If the carriage was moving but never stopped on the end limits the limit
sensor is inoperative. Check sensor operation in service mode.
If the motor was running while the keyboard was not operated and no buttons operate, defective
keyboard.

Er 22 Temple rest motor time out

If this motor runs more than 3 seconds continuously this time out error is generated and all action
is stopped.
Motor or motor cables broken if motor is not running
Motor limit detector inoperative. Check in service mode.

Er 23 Layer adjust motor time out

If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running
If keyboard button was operated all the time the reason is either that the layer motor cable is bro-
ken (no movement or sound) or the carriage is jammed (loud sound can be heard). If the carriage
was moving but never stopped on the end limits the limit sensor is inoperative. Check sensor
operation in service mode. End limits do not stop the motor in service mode, be careful not to
break the mechanism!
If the motor was running while the keyboard was not operated and no buttons operate, defective
keyboard.

Er 24 Primary slot motor time out

If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running
The calibration sensor is inoperative. Check in service mode. Note that the sensor operating volt-
age is on only when the calibration sequence is performed in order to avoid aging of the sensor.
In service mode the voltage is continuously on.

Er 25 Cassette motor time out

If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running.
The end limit detector(s) are inoperative or misplaced. Check in service mode. The sensor mag-
nets should be placed in such a positions that it is not possible to move the cassette over the lim-
its. Check both the cassette holder and the holder carriage limits.

Er 26 Rotation motor time out

If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running.
The start position sensor is inoperative or the rotating arm has been pushed over to wrong side
of the limit sensor. Check in service mode and/or push the arm towards center.
Check that the friction drive is not slipping.

Er 27 Cephalostat scanning mechanism time out.

If this motor runs more than 25 seconds continuously this time out error is generated and all
action is stopped. Check that the movement is not obstructed.
Limit sensor cable is loose or broken.
Motor or cables broken if motor is not running.

Er 28 Panoramic sensor head motor time out

If this motor runs more than 10 seconds continuously this time out error is generated and all
action is stopped.
The wrongly installed Frankfort light or a cable prevents the sensor head from reaching the pan-
oramic position.
The safety limit switch is pressed and the movement of the sensor head is prevented.

3.5 Errors 30-33 (generator errors)

Er 30 kV value does not reach given value

If the kV value remains more than 6 kV below the desired value (in service mode if kV does not
exceed 35 kV) this error is indicated.
- kV feedback cable short circuit
- Defective tube head
- Defective generator
- Defective generator processor board
- Check operating voltages and locate fault by replacing boards
- see Er 11

Er 31 mA value does not reach given value

If the mA value remains more than 1 mA below the desired value (in service mode if mA does not
exceed 0.5 mA) this error is indicated.
- mA feedback cable short circuit
- Faulty tube head filament power cables
- Faulty x-ray tube filament
- Power generator tube filament power supply inoperative
- Defective generator processor board
- Check operating voltages and locate fault by replacing boards
- If it appears between Er 11 and continuous Er 30, most likely defective tube head

Er 32 Tube filament control inoperative

If the mA value exceeds more than 1 mA the desired value during exposure this error is indi-
cated.
Error during exposure:
- mA feedback opened during exposure (try new exposure Er 32)
- Filament power supply broken during exposure (try new exposure to see if Er 33 occurs)
- Generator processor board measuring circuits broken during exposure. (Try new exposure to
see if Er 33 occurs)

Er 33 Tube filament control inoperative

After 2 seconds pre-heat period the tube filament voltage must be within 0.1V. If not, this error is
indicated.
Error in the beginning of the exposure:
- Generator operating voltage missing (mains)
- Tube filament short circuit
- Generator board filament power supply defective (likely when after Er 11)
- Check operating voltages and locate fault by replacing boards.

3.6 Errors 40-43 (mechanical errors)

Er 40 Rotation remains short

At the end of the panoramic exposure the rotation end sensor must be reached. If not, this error
is indicated.
- Friction drive slipping (surfaces, motor spring)
- Inoperative sensor
- Sensor misplaced
- Check in service mode and adjust if necessary

Er 41 Rotation too long

At the end of the panoramic exposure the rotation must not go over the end sensor. If so, the
operation is stopped with this error indication.

Technical Manual Planmeca Proline CC panoramic x-ray C-7

Chapter C - HELP & ERROR MESSAGES

- Friction drive slipping forward (centering spring drawing it to this forward direction)
- Inoperative sensor (giving pulses, not good signal)
- Check in service mode and adjust if necessary

ER 42 Secondary slot not locked

The secondary slot was not locked into position (CEPH units only).
After returning from CEPH mode, the secondary slot did not engage with the slot on the top of the
secondary slot. Return the unit to the CEPH mode and then back to PAN mode.
Enter the service mode. If the square incisor light is not on, the sensor magnet must be adjusted.
If the square incisor light is on, the solenoid needs to be adjusted.

Er 43 Secondary slot out of position

The secondary slot is out of position in CEPH mode (CEPH units only).
The secondary slot has moved with the soft tissue filter. This would cause the beam to be atten-
uated and possibly cause the patients nose to be cut of film when making a lateral CEPH expo-
sure.
The magnet that hold the secondary slot in position or the sensor needs adjustment. Probably
both.

Er 44 The patient positioning mechanism zero point set incorrectly

The patient positioning mechanism can not reach the -24 position.
Loosen the patient positioning mechanism screws and move the mechanism backwards. Try to
calibrate the mechanism again. If the position -24 is not reached, remove the patient position
mechanism from its place and file the holes in front of the mechanism so that the mechanism can
be positioned back enough.

Er 45 The soft tissue filter position not calibrated

The soft tissue filter position must be calibrated. If not, this error is indicated.
Perform the calibration according to instructions given in section “Soft tissue filter positioning light
calibration and adjustment” on page D-40.

3.7 Errors 50-57 (connector or cable errors)

Er 50 Temperature sensor shorted

Before each exposure and after pressing READY or kV, mA adjustments the temperature of the
tube head is measured. If the result is too low it is assumed that the sensor is short circuiting.
Sensor broken. Measure the resistance that should be 1000 ohms at 25 °C. If not near, replace.
If disconnecting the cable to cassette end limit sensor board cures this error, then this cable and/
or sensor board is partially shorting the + 15V.
Check in service mode the measured temperature. If still low with cables disconnected, faulty
generator processor board.

Er 51 Temperature sensor open (overpressure when applicable)

Before each exposure and after pressing READY or kV, mA adjustments the temperature of the
tube head is measured. If the result is too high it is assumed that the sensor is open circuit. In
some models there is an overpressure sensor in the tube head, connected in series with the tem-
perature sensor and breaking the circuit at overpressure. Also, if the tube head and generator
processor grounds are not properly connected to the protective earth this error will be indicated.
Check the earthing cables.
If seems ok by resistance measurement (about 1000 ohms at 25°C) then the generator proces-
sor board is faulty.

C-8 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter C - HELP & ERROR MESSAGES

Er 52 mA or kV feedback cable open

Before each exposure and after pressing READY the kV and mA feedback signals are meas-
ured. If the result is too high it is assumed that the cables are not properly connected.
If seems ok by resistance measurement (kV about 16 kΩ, mA about 383R), measured at the
generator processor board inputs while cables connected, the board is faulty.

Er 53 Up/down motor does not consume power

If this error occurs, check the up/down motor condition and the motor cables.

NOTE If the unit is equipped with the STOP switch, check that it is not activated.

Er 54 Up/down motor consumes too much power

There can be a fault on the up/down motor control electronics. This error can also occur because
of the up/down motor cable short circuit, or if the motor is jammed.

Er 57 Exposure button activated

If the exposure circuit is activated when the unit is turned on or service mode is entered, Er 57
occurs. This is to prevent unintentional exposures.

3.8 Errors 60-61 (generator processor and AEC related errors)

Er 60 Supply voltage ± 15 too low

Generator processor board analog circuits have operating voltages of ±15V.
If these are below about 12.5V this error is indicated.
If disconnecting the cable to cassette end limit sensor board cures this error, then this cable and/
or sensor board is shorting the + 15 V.
Otherwise faulty generator processor board.

Er 61 Generator processor does not respond

If the generator processor is not responding to the calls of the keyboard (master) processor oper-
ation is stopped with this error indication.
- +33 V operating voltage below 24 V.
- Serial communications cable broken
- No power to the generator processor
- One sensor is shorting the generator processor +5 V
- Faulty software EPROM in the generator processor
- Generator processor defective
- Measure voltages and cables to locate problem. Try to disconnect sensors and motors from
generator processor. Replace EPROM.

Er 62 Limit sensor power missing

This error occurs when the power detected from the Keyboard CPU limit sensor: up/down, layer
or temple rest is missing. Check the sensors. Replace the Keyboard processor board.

Er 64 The radiation reaching the AEC sensor is very low or missing completely
Check that the cassette is AEC compatible, i.e. marked with text “AEC COMPATIBLE”. If the
cassette type is correct, perform the AEC calibration, refer to section “AUTOMATIC EXPOSURE
CONTROL (AEC) CALIBRATION” on page D-26. If the calibration does not correct the situation,
change the AEC slide frame assembly.

Er 65 The radiation reaching the AEC sensor is too high

If the cassette is in the cassette carriage and the patient is positioned when this error occurs, per-
form the AEC calibration, refer to section “AUTOMATIC EXPOSURE CONTROL (AEC) CALI-
BRATION” on page D-26. If the calibration does not correct the situation, change the AEC slide
frame assembly.

Technical Manual Planmeca Proline CC panoramic x-ray C-9

Chapter C - HELP & ERROR MESSAGES

3.9 Errors 70-75 (software errors)

Er 70 Conflicting commands in communications line

If the generator processor is receiving conflicting commands from the keyboard processor (for
example drive cassette back and forth at same time) the operation command is ignored, all activ-
ity is ceased and this error code is sent to the keyboard processor to be put on the display.
- Not matching software versions in generator and keyboard processors
- Faulty keyboard processor board

Er 71 Generator processor program memory failure

At power up the generator processor calculates a check sum from the program memory circuit
(EPROM). If it doesn’t match all operation is ceased and an error code is sent to keyboard proc-
essor. If the EPROM is completely broken it is obvious that this kind of error code cannot be sent
but more likely the Er 61 will be displayed. This error indication is merely meant to detect a single
EPROM failure before complete break down.
- The generator processor EPROM is to be changed immediately

Er 72 Keyboard processor program memory failure

At power up the keyboard processor calculates a check sum from the program memory circuits
(EPROM). If it doesn’t match all operation is ceased and an error code is displayed. If the
EPROM is (are) completely broken it is obvious that this kind of error code cannot be displayed
but more likely the equipment does nothing. This error indication is merely meant to detect a sin-
gle EPROM failure before complete break down.
- The keyboard processor EPROMs are to be changed immediately

Er 73 Keyboard processor program error

If the keyboard processor detects an illegal command (from EPROM) it will stop and give this
error indication. Most likely faulty component on the keyboard processor board. A single hazard-
ous code error is also possible.
- If appears more than once, replace keyboard processor board.

Er 74 Keyboard processor operating improperly

There is a so called watchdog circuit both in the generator processor and in the keyboard proces-
sor. If the microprocessor does not perform its program but is running wildly, this circuit will stop
the operation within 0.1 second. If it was only a hazardous error the microprocessor will recover
and indicate this error. If there is a serious problem on the keyboard processor board the equip-
ment will most likely do nothing and blank the display after this kind of an error. Replace the key-
board processor board.

NOTE If the generator processor is not working properly the error is indicated by Er 61. In some
cases it might happen that the improperly operating generator processor generates Er 74
by overloading the keyboard processor. Check by disconnecting generator processor.

Er 75 Keyboard processor operating improperly

The keyboard processor has a peripheral IC called ASIC (PM 2002IC) which controls input and
output functions of the CPU board. This chip has for some reason lost its configuration and the
microprocessor has detected it.
- If appears more than once, replace keyboard processor board.

3.10 Errors 80-83 (microprocessor chip errors)

Er 80 Keyboard processor EEPROM failure

There is some non volatile memory for various parameters in the microprocessor chip itself. The
writing of this memory is limited to a minimum of 10 000 times that is in practice 20 years of
equipment life.
However, if this memory did fail, this error is indicated.

Take an exposure. Hold the exposure down for the duration of the exposure.

CAUTION Radiation is generated when exposure button is pressed.

Press the return key to drive the cassette to the loading position, remove the cassette and proc-
ess the film.
The images of 23 balls should appear on the film (Fig. 15). They should be round, all the same
size, and evenly spaced. Note that they will not necessarily be at the same vertical height. The
outermost balls on the left and right sides should appear symmetrically. If the distance from the
outermost ball to the edge of the exposed area on the right side differs more that 2mm from the
corresponding distance on the left side, the rotation start limit must be adjusted (see section
“Rotation limits” on page D-23). Note, that the adjustment of the patient positioning mechanism
must be performed first.
The distance from the center of the middle ball to the center of the rear middle ball should be less
than 2mm. If the distance is not correct you will have to adjust the position of the patient position-
ing mechanism (see section “Patient positioning mechanism adjustment” on page D-14).

The distance from the center of the middle ball to the center of the tenth ball to the left and the

tioning mechanism need not be adjusted, and you should then check the patient positioning
lights (see section “PATIENT POSITIONING LIGHTS” on page D-19).
If these distances are not correct you will have to adjust the position of the patient positioning
mechanism. The following diagrams are a rough guide as to how to position it correctly. Note that
you may have to make more than one adjustment as the patient positioning mechanism could be
incorrectly positioned in more than one direction. For example it may be too far forward and too
near the column.

5 MECHANICAL ADJUSTMENT OF THE ROTATIONAL PART

When designing the unit we aimed at minimizing need for adjustments in connection with assem-
bly and service. The technique used, particularly guidance electronics, has permitted us to elimi-
nate most adjustments, but there are still certain adjustments to be done.
Some of the adjustments related to the mechanics of the unit cannot be done without special
tools (alignment tools). It is important therefore to check that all special tools for assembling the
unit are available, see “REQUIRED TOOLS” on page D-2.

5.1 Guiding profile and counterprofile

The clearance between the guidance profile and the counterprofile can be checked and adjusted
if necessary when the loading spring of the drive wheel is removed. Also the drive wheel with
transmission can be removed, but this is not necessary. Note that all major parts must be
installed so that the rotational part has about its final weight.
Provided that these requirements are fulfilled the clearance can be observed by moving the rotat-
ing unit sidewards from both ends (see figure below). Note that the rotating unit has to be half
way trough the rotating cycle. When moving the rotating unit parallelly sideways the longitudinal
clearance appears as clearance.

Figure 33
If there is any clearance it is eliminated by unscrewing screws (see figure below) and pushing the
counterprofile towards the cassette mechanism. Do not use any tools to move the counterprofile.
Tighten the screws by pressing the screw head with finger. Check once more that there is no
clearance left but also that the contact between the counterprofile and the guidance profile is not
tight. This can be done by carefully pushing the rotating unit from the cassette end using the
same speed at which it moves when it is driven by the stepper motor and turn it approximately
45Ž to both directions. If there is too much tension, the movement is stiff and continually sticks in
the middle area.

Figure 34

Technical Manual Planmeca Proline CC panoramic x-ray D-21

Chapter D - ADJUSTMENT & CALIBRATION

5.2 Adjustment of the guidance wheel

The guidance wheel can be adjusted if the driving wheel with gear is detached and clearance
between guidance and counter profile and is correctly adjusted. The guidance wheel is attached
to the rotating unit (1) through a flange (2). The flange is fixed to the rotating unit with screws (3)
and a bolt pin (4). By unscrewing the screws (3) the flange can be turned around the bolt pin (4).

Figure 35
The guidance is adjusted when the rotating unit is in a position corresponding to the middle point
of the exposure. In principle, the guidance wheel should be placed as near the inner edge of the
groove as possible. For proper adjustment turn the rotating unit with both hands. Always turn the
rotating unit from the cassette head end and move it throughout the rotating cycle calmly and at a
speed corresponding to the actual speed. If the guidance wheel has been adjusted too far from
the inner edge of the groove, a clack of the counter profile meeting the guidance profile can be
heard when moving the unit from the start position to the middle position. If the guidance wheel
has been adjusted too close to the inner edge of the driving groove the movement is sticky in an
area corresponding to a 45° angle in relation to the central area. The adjustment can be found
only by experimenting.

D-22 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter D - ADJUSTMENT & CALIBRATION

5.3 Rotation limits

NOTE The adjustment of the patient position mechanism must be performed before adjusting
the rotation limits.

The rotating movement is controlled by two Hall detectors: one determines the start position and
the other the end position. The latter has no importance for the normal function because the step
motor drives the rotating unit according to the programmed number of steps The end limit is of
great importance in case of abnormal function, because it informs the processor that the rotating
unit has not reached the end position.
The start limit is adjusted so that the movement of the guidance wheel in the drawing groove is
symmetric to the groove. The distance of the boss of the wheel from the end of the groove should
be the same both when the movement starts and when it ends. The symmetricity of the move-
ment has more importance to the quality of the radiograph than the absolute length of the move-
ment which varies a little because of production tolerances.
Remove the necessary covers. Slide the ball phantom into the patient positioning mechanism.
Check that the y-line on the ball phantom is parallel to the line on the underside of the alignment
ruler according to instructions given in section “Patient positioning mechanism adjustment” on
page D-14.
Remove the alignment pin. Enter the test mode if you are not already in it.
Press the ready key to drive the x-ray unit to the exposure position. When the x-ray is ready the
READY indicator light will come on. Place the alignment ruler in position between the primary and sec-
PRET
ondary slot and write down the angle between the ball phantom “start”-line and the alignment
ruler.

Start to take a test exposure by pressing and holding down exposure button on the remote con-
trol until the rotation unit has reached the end position. Place the alignment ruler in position
between the primary and secondary slot and write down the angle between the ball phantom
“end”-line and the alignment ruler.

The positions corresponding to end and start positions should not differ more than ± 1 mm. The
position of the start limit (Hall detector) can be changed by unscrewing the screws. This should
be repeated until the tolerance area is reached.
The adjustment of the end position is done after the start position has been adjusted.
No special tools are needed. The end limit should activate about 5 mm before the end of the
movement and it should activate even when the rotating unit is at 5 mm past the end position.
The indicator light shows this when the equipment is in the service mode.

8 AUTOMATIC EXPOSURE CONTROL (AEC) CALIBRATION

NOTE If the x-ray unit is equipped with optional Automatic Exposure Control (AEC), the AEC cal-
ibration must be performed after the AEC retrofit kit installation and whenever the pano-
ramic x-ray beam is adjusted. The AEC calibration is performed after the panoramic x-ray
beam adjustment.

Perform the AEC calibration in the following order:

1. Check/adjust the panoramic x-ray beam.
2. Adjust the positions of primary slots number 0 and 1 so that the AEC signal value is as large as
possible.
3. Adjust the base value so that the film density is 1.0 ±0.1 OD.
4. Adjust the AEC detector offset value (base signal) to value 8 ±2. The offset value is shown on
the main display when the unit is in the AEC mode and no exposure is taken.
5. Adjust the AEC-signal value to approx. 60. During the exposure this AEC-signal value is
shown on the main display.
6. Fine adjust the AEC-signal in normal mode.

8.1 Checking/adjusting the primary slot position

After the panoramic x-ray beam adjustment the AEC-signal for primary slots number 0 and 1
must be checked. The position of the slot must be adjusted so that the AEC-signal value is as
large as possible, and the value for the primary slot number 1 must be equal to the value for pri-
mary slot number 0.
Enter the service mode: press the CTL-key and simultaneously press and hold down the cepha-
lometric mode selection (CEPH) key until the temperature of the tube head appears on the dis-
CTL
+ CEPH
play (about four seconds). The ready key indicator light will start to flash. This indicates that you
have entered the service mode.

AUTO Enter the AEC mode by pressing and holding down the auto key until the indicator light will come
on.

Place the AEC calibration filter to the front of the first primary slot.

CAUTION Radiation is generated when the exposure button is pressed. Take adequate protection
measures. Keep the exposure time as short as possible.

During the exposure the AEC-signal is shown on the main display. Adjust the slot position in hor-
U nn izontal direction until the signal reaches its maximum value as follows.

Press the CTL and press and hold down the primary slot key for 4 seconds to enter the beam
CTL alignment mode.

hold for 4
seconds

° Adjust the position of the beam by pressing the patient positioning (mm) keys. The minus key will
mm
move the slot mechanism, and beam to the left, and the plus key will move the slot mechanism,
and beam to the right. The primary slot adjustment in horizontal direction is described in section
“Radiation beam too far to the right or left” on page D-8.

Check the x-ray beam position with the beam alignment tool after the adjustment. If the beam
image is not within the borders of the rectangle marked on the alignment tool, adjust the beam
position slightly.

After the primary slot number 0 has been adjusted, select the primary slot number 1 and adjust it
1 in the same way. Make sure that the value for the primary slot number 1 equals to the value for
the primary slot number 0.

Check the x-ray beam position with the beam alignment tool after the adjustment. Adjust the
beam position slightly, if needed.

NOTE Remove the AEC calibration filter from the primary slot before selecting the primary slot
number 1. Position the AEC calibration filter to the front of the second primary slot before
adjusting the AEC-signal.

8.2 Base value adjustment

The default kilovolt value, i.e. the value that is used when the AEC exposure starts, is 68 kV. The
film density is adjusted by changing the default milliampere value. The adjustment range is from
-3 to +3. The density value 0 corresponds the mA value 8. Changing the density value will
change the mA value as follows: one density step equals to one mA step. The negative value
decreases the mA value from the value 8mA, whereas the positive value increases it.

Density

68 5 -3
68 6 -2
68 7 -1
68 8 0
68 9 1
68 10 2
68 11 3

To find the exposure values that give the film density closest to value 1.0 ±0.1 OD the test expo-
sures are taken. The films are either compared to the reference film which density is approx. 1.0
OD (supplied with the system), or the film density is measured using a film densitometer.
It is recommended to start with exposure values 68kV and 7mA and check the film density. In
case other exposures are needed, decrease/increase the mA value until the correct film density
is achieved.

Place the AEC calibration filter to the front of the first primary slot (primary slot number 0).

Move the cassette carriage to the loading position.

In the darkroom open the cassette and place a film inside the cassette. Close the cassette. Slide
the cassette into the cassette holder.

NOTE The film density adjustment must be performed in normal panoramic mode. Make sure
that the unit is NOT in the AEC mode, i.e. make sure that the auto key indicator light is
NOT on.

Select a kilovolt value of 68 and a milliampere value of 7.

8.3 Adjusting the AEC-signals

NOTE Take five 10 seconds exposures in the service mode with a kilovolt value of 68 and a milli-
ampere value of 7 before adjusting the AEC-signals.

Make sure that the unit is in the service mode and that the AEC mode is selected. If needed,
enter the AEC mode by pressing and holding down the auto key until the indicator light will come
on.

In the service mode the AEC detector offset value (base signal) is shown on the main display
U 8 when the unit is in the AEC mode and no exposure is taken. Set the offset to value 8 ±2 with the
offset adjustment trimmer located on the Cassette limit PCB. Turning the trimmer clockwise
increases the value and turning it counterclockwise decreases it.
AdjAEC.eps

Adjust the offset.

After the offset value is set the AEC-signal during the exposure is adjusted.
Make sure that the primary slot number 0 is selected (the horizontal sector display is empty).
Check that the aluminium block is in front of the slot.

In the darkroom open the cassette and place a film inside the cassette. Close the cassette. Slide
the cassette into the cassette holder.
Protect yourself from radiation and press the exposure button.

CAUTION Radiation is generated when the exposure button is pressed. Take adequate protection
measures. Keep the exposure time as short as possible.

D-30 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter D - ADJUSTMENT & CALIBRATION

During the exposure the AEC-signal value is shown on the main display. Set this value to approx.
U 60 60 with the gain trimmer located on the Cassette limit PCB. Turning the trimmer clockwise
decreases the value and turning it counterclockwise increases it. Repeat the adjustment until the
AdjAEC.eps
correct value has been reached.

Adjust the AEC-signal with the gain trimmer.

NOTE The final adjustment of the AEC-signal during the exposure must be done in the normal
mode.

Final adjustment in normal mode

NOTE In the normal mode the AEC-signal is only shown on the main display if you previously
were in the film density adjustment mode. In case the AEC-signal is not shown on the
main display, enter the service mode and enter the film density adjustment mode. Then
exit the film density adjustment and the service modes and the signal can be seen on the
main display.

CEPH To exit the service mode press the CEPH key briefly.

Chapter D - ADJUSTMENT & CALIBRATION

After the exposure the difference between the offset value and the AEC-signal during the expo-
U 51 sure is shown on the main display. Set this value to 51 ±1 with the gain trimmer located on the
Cassette limit PCB. Repeat the adjustment until the correct value has been reached and check
the value by taking at least two exposures.

Check the value for the primary slot number 1 and adjust the slot position in horizontal direction,
if needed. Do not adjust the value by turning the trimmer.

NOTE Remove the AEC calibration tool from the primary slot before selecting the primary slot
number 1. Position the AEC calibration tool to the front of the second primary slot
(number 1) before adjusting the AEC-signal.

NOTE In the service mode the difference between the offset value and the AEC-signal value of

2.4 Radiation beam adjustment

NOTE In case the radiation beam is not correctly aligned first check the sensor head position by
using a spirit level. The sensor head (i.e. the sensor alignment tool) must be perpendicu-
lar to the rotating unit (see Fig. 20 on page E-15), otherwise the angle of the quick connec-
tor mechanism must be adjusted according to the instructions given in section “Adjusting
the sensor head position” below.
After adjusting the sensor head position adjust the primary slot according to the instruc-
tions given in sections “Primary slot adjustment - radiation beam too low, high or not ver-
tical” on page E-16 and “Primary slot adjustment - radiation beam too far to the right or
left” on page E-17, if needed.

Adjusting the sensor head position

In case the sensor head is attached to the rotating unit, remove the sensor head from the quick
connector mechanism (see instructions given in Planmeca Proline CC panoramic x-rays user’s
manual), or remove the fixed sensor head from its adapter (refer to section “Removing and
attaching the fixed sensor head” on page E-4).
Remove the adapter covers. Refer to section “Removing and attaching the fixed sensor head” on
page E-4 or to section “Sensor head with quick connector mechanism - removing the covers” on
page E-9.
Attach the sensor alignment tool to the adapter.
Loosen the two screws located on the outer side of the mechanism with the 3 mm allen key (see
Fig. 19 below).

Loosen these screws.

Adjust the head angle with
these screws.

The outermost balls on the left and right sides should appear symmetrically. If the distance from
the center of the middle ball to the center of the tenth ball on the right side differs more than 2mm
from the corresponding distance on the left side, the rotation start limit must be adjusted (in the
same way as in the film-based panoramic x-ray, see section “Rotation limits” on page D-23).
Note, that the adjustment of the patient positioning mechanism must be performed first.
The distance from the center of the middle ball to the center of the rear middle ball should be less
than 2mm. If the distance is not correct you will have to adjust the position of the patient position-
ing mechanism (see section “Patient positioning mechanism adjustment” on page E-31).

The images of 23 balls should appear on the image (Fig. 51). They should be round, all the same
size, and evenly spaced. Note that they will not necessarily be at the same vertical height. The
outermost balls on the left and right sides should appear symmetrically. If the distance from the
center of the middle ball to the center of the tenth ball on the right side differs more than 2mm
from the corresponding distance on the left side,, the rotation start limit must be adjusted (in the
same way as in the film-based panoramic x-ray, see section “Rotation limits” on page D-23).
Note, that the adjustment of the patient positioning mechanism must be performed first. The dis-

NOTE Before you can measure the true distance between the balls, you have to define a refer-
ence distance as follows:
Click the CAL button and then draw a long horizontal line to the image by clicking the
start point, releasing the mouse button and clicking the end point. The Reference distance
window appears.
Calculate the line length using the formula A x 0.132mm = B, where A is the distance in
pixels and B is distance in millimetres. Enter the value B (line length in millimetres) to the
Reference distance window and click OK.
The distance from the center of the middle ball to the center of the tenth ball to the left and
the tenth ball to the right can now be measured.

The distance from the center of the middle ball to the center of the tenth ball to the left and the
tenth ball to the right should be 120mm ± 2mm. If this distance is correct then the patient posi-
tioning mechanism need not be adjusted, and you should then check the patient positioning
lights (see section “PATIENT POSITIONING LIGHTS” on page D-19).
If these distances are not correct you will have to adjust the position of the patient positioning
mechanism. The following diagrams are a rough guide as to how to position it correctly. Note that
you may have to make more than one adjustment as the patient positioning mechanism could be
incorrectly positioned in more than one direction. For example it may be too far forward and too
near the column.

The bite piece of the chin rest can be removed and cleaned with alcohol-based solutions. The
patient support handles can be cleaned with alcohol-based solutions.
Other unit surfaces can be cleaned with a soft cloth damped in a mild cleaning solution.

1.2 Operator’s checks

Exposure indicators
Confirm that the exposure indicator lights turn on in the control panel and in the remote control
for the length of the exposure.

Exposure warning signal

Confirm that the buzzer comes on for the length of the exposure. If needed, adjust the tone of the
signal, see section “EXPOSURE WARNING SIGNAL ADJUSTMENT” on page D-25.

Exposure switch
Confirm that the exposure switch requires continuous activation to maintain the exposure.
Releasing the exposure switch during the radiation should produce the ER00 message on the
displays (clear it by pressing the CTL-key once). Make a visual check that the exposure switch
spiral cable is not damaged.

Labels
Check that no labels are detached or worn and that they are all legible.

2 PREVENTIVE MAINTENANCE CHECKS

2.1 Electrical checks

Annually or after every 10 000 exposures whichever appears first the electrical exposure param-
eters of the Planmeca Proline CC Panoramic X-ray should be checked in order to maintain the
initially accurate operation of the equipment despite of the possible long term component value
alterations.
There are no adjustments in the equipment because of its’ self-calibrating microprocessor based
operation and therefore no actual parameter trimming of the kV, mA and exposure time can be
done.If one of the parameters to be checked by this periodical preventive maintenance proce-
dure is found to be beyond the limit values allowed, the corresponding electrical circuit board is to
be changed in whole and sent back to the factory for recalibration that is done by replacing the
faulty component.
The parameters to be checked are the following:
Before exposure:
• kV measurement circuit impedance
mA measurement circuit impedance

During exposure:
• kV value
• mA value
• exposure time

In order to perform the calibration measurements the x-ray equipment must be powered off and
the rotating arm bottom cover is to be removed. The generator processor board connectors P2
and P13 are disconnected from their connectors and the PM 2002 CC Panoramic X-ray Calibra-
tion unit (order No. 50980) is connected in between these connectors. Please, be certain that the
calibration unit is connected to both the cable end connectors and to the generator processor
board connectors.
Before powering on the x-ray equipment the circuit impedance measurements should be per-
formed in order to verify the condition of the measurement resistors in the tube head and the
operational amplifier input resistors on the generator processor board.
Because the calibration unit is battery operated first put it in the BATT mode and check that the
battery voltage is above 8 V. Note that the battery check loads the battery and should therefore
be done shortly to avoid unnecessary battery discharge.

kV measurement circuit impedance measurement

Select for kV measurement and resistor mode and read the calibration unit display.
Acceptable value is from 16.20 kohms to 16.80 kohms.
If the value is not within the limits disconnect the calibration unit from the generator processor
board and make a new measurement to measure the tube head resistor only.
Acceptable value is from 17.70 kohms to 18.30 kohms.
If this result was within the limits the generator processor must be replaced. If this was not within
the limits the tube head must be replaced.

F-2 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter F - PREVENTIVE MAINTENANCE

mA measurement circuit impedance measurement

Proceed as measuring the kV circuit but select for mA measurement. Both measurements (if the
latter is needed) should give a resistance value from 378 ohms to 387 ohms. If both results were
out of limits the tube head must be replaced. If only the first result was out the generator proces-
sor must be replaced.
If the first two tests passed check that the calibration unit is connected both to the cable end con-
nectors and to the circuit board connectors and power on the x-ray equipment. After the self test
phase has passed enter the service mode to avoid unnecessary rotation while measuring kV and
mA values.

CAUTION Put the lead radiation protection plate in front of the collimator to avoid radiation during
measurements.

kV - measurement
Select for kV value measurement and select x-ray equipment for kV values from 60 kV to 80 kV
(selected mA value has no effect but 2 mA is recommended to avoid unnecessary radiation),
press the exposure switch at each kV value and read the calibration unit display when the gener-
ator is on (warning sound of higher pitch can be heard), allow few seconds to the calibrator to
settle. The results must be the values selected ± 2.5 kV. If not, the generator processor board is
to be replaced.

CAUTION DO NOT OPERATE THE RESISTOR/BATT BUTTON WHILE THE X-RAY IS OPERATING.
DOING THIS MAY CAUSE PERMANENT DAMAGE TO THE TUBE HEAD.

mA - measurement
Select for mA value measurement and select x-ray equipment mA values from 2 mA to 12 mA
(selected kV value has no effect but 60 kV is recommended to avoid unnecessary radiation),
press the exposure switch at each mA value and read the calibration unit display when the gen-
erator is on (warning sound of higher pitch can be heard), allow few seconds to the calibrator to
settle. The results must be the values selected ± 1.0 mA. If not, the generator processor board is
to be replaced.

CAUTION DO NOT OPERATE THE RESISTOR/BATT BUTTON WHILE THE X-RAY IS OPERATING.
DOING THIS MAY CAUSE PERMANENT DAMAGE TO THE TUBE HEAD.

Exposure time measurement

Enter the x-ray equipment normal operation mode because the rotation is needed for the expo-
sure time measurement. (For cephalostatic exposure time measurements enter the cephalostatic
mode). Select the calibrator exp.time measurement mode. Select 70 kV and 10 mA and push
ready button. (70 kV and 10 mA must be selected for the exposure time measurement because
the calibration unit counts the time from 50% rising edge to 50% falling edge of the kV and mA
values using 35 kV and 5 mA limit values). Push the exposure switch till the end of the panoramic
(or cephalostatic) exposure and then read the calibration unit display. Starting an exposure will
clear the time display.If the exposure switch was released before the end of the exposure Er 00
is displayed on the x-ray equipment clock display and the measurement is invalid.Selecting for
kV or mA exp.time will measure the exposure time from kV over 35 kV or mA over 5 mA, respec-
tively.

CAUTION DO NOT OPERATE THE RESISTOR/BATT BUTTON WHILE THE X-RAY IS OPERATING.
DOING THIS MAY CAUSE PERMANENT DAMAGE TO THE TUBE HEAD.

Technical Manual Planmeca Proline CC panoramic x-ray F-3

Chapter F - PREVENTIVE MAINTENANCE

When using various focal trough forms or when in cephalostatic mode the exposure time varies.
The selected time can be seen from the x-ray equipment exposure time display and the meas-
ured time must correspond to that within ± 10%. If not, the generator processor must be replaced
and most likely also the keyboard processor. That is because the processor clocks are synchro-
nized to each other and variation in exposure times can only be due to the processor clock fre-
quency alteration that must appear in both processors within 1%. If the time differs from the
selected one because of some other reason, an error indication will always be present.

4 EQUIPMENT COMPLETELY DEAD

If the equipment cannot be started at all the following steps must be taken to locate and repair
the equipment.

4.1 Check the mains outlet voltage to be within limits. (±10% of nominal voltage)

a) Check the main fuses near the mains switch below the lower fixed part. If the fuses were OK take
step 4, if not take step 3.

b) Replace the fuses only with fuses of the same rating. With power off open the lid on top of the
upper fixed part and detach connector P3 from the low voltage power supply board. If fuses hold
take step 4, if not there is a short circuit in the mains wiring from mains switch to the filter in upper
fixed part, in the mains wiring from the filter to the loose connector P3 or the mains filter is
defective.

c) With power off open the lid on top of the upper fixed part if it was not already open, connect
connector P3 if it was taken off. If the fuse F3 was blown, it could be a result from an occasional
overvoltage in the mains. To check this replace the fuse and power on. If everything operates
normally this was the case, if the fuse blows again detach connectors P1, P2, P4 and P5. Check
all the fuses on the low voltage power supply board and replace if necessary with fuses of the
same rating. If the fuses hold take step 5, if not replace the low voltage power supply board.
Check that the primary voltage setting is the same.

d) Connect connector P2 while powered off. If the fuses hold when powered on take step 6. If not,
there is a short circuit to the protective earth in the mains wiring from this board to the tube power
generator board or on the tube power generator board itself. If the relay K2 on the low voltage
power supply board is inoperative and is connecting all the time the board must be replaced but
there is also a short circuit between the mains live wires from this board to the tube power
generator board or on the tube power generator board itself. Open the bottom cover of the
rotating part and detach the tube power generator board connector P1. If fault remains, replace
the cable harness. If not, replace the tube power generator board.

e) With power on measure the voltage across GND and +VCC labeled connector pins on either
connector P1 or P4. If it is within 30 - 39 VDC, take step 7, otherwise replace the low voltage
power supply board. Check that the primary voltage setting is the same.

Technical Manual Planmeca Proline CC panoramic x-ray G-5

Chapter G - TROUBLESHOOTING

f) Power off and wait for 1 minute to allow the capacitors to discharge. Connect connector P1. If the
fuses hold when powered on take step 8.
If not, there is a short circuit in the cable harness from this board to the generator processor or in
the generator processor and the circuitry connected to it. Open the bottom cover of the rotating
part and detach the generator processor board connector P5. If a fuse blows, replace the cable
harness. If not, power off and connect P5 to the generator processor board and detach all the
other connectors from it. Check the fuse on the board and replace if necessary. If a fuse blows
when powered on, replace the generator processor board (see chapter Circuit boards/generator
processor). If not, power off and connect the connectors back to the generator processor board
one at a time checking every time for the fault to reappear. Check the cable that caused the fault
and all the circuitry connected to it. Replace the defective parts.(see appropriate chapters for
adjustments that should be made).

g) Power off and connect connector P4 to the low voltage power supply board. Open the lower fixed
part cover and detach connector P1 from the keyboard processor board. If the fuses hold when
powered on take step 9.
If not, there is a short circuit in the cable harness from the low voltage power supply board to the
keyboard processor board. Replace the cable harness.

h) Power off and connect P1 to the keyboard processor board and detach all the other connectors
from it. Check the fuse on the board and replace if necessary. If a fuse blows when powered on,
replace the keyboard processor board (see chapter Circuit boards/keyboard processor). If not,
power off and connect the connectors back to the keyboard processor board one at a time (leave
the connector P7 out) checking every time for the fault to reappear. Check the cable that caused
the fault and all the circuitry connected to it. Replace the defective parts.(see appropriate
chapters for adjustments that should be made). If the fuses didn’t blow take step 10.

i) Power off and connect P7 to the keyboard processor board. Open the keyboard housing and
detach connector P2 from the keyboard/display board. If the fuses hold when powered on take
step 11. If not, there is a short circuit in the cable harness from the keyboard processor board to
the keyboard/display board. Replace the cable harness.

j) Power off and connect P2 to the keyboard/display board and detach connector P1. Check the
fuse on the board and replace if necessary. If a fuse blows when powered on, replace the
keyboard/display board. If not, the system should now start normally and you can take the step
12. If the display is still blank, look at the keyboard processor board for a red LED. If it is off or
blinking, replace the board. If it is continuously illuminating, replace the keyboard/display board.
If neither did help, power off and detach connector P1 from the low voltage power supply board.
If the system now starts, the fault should be located on the generator processor board. Replace
(see chapter Circuit boards/generator processor).

k) Power off and connect connector P1 to the keyboard/display board. Turn the rotating part
manually to the starting point (on the sensor) if it was not there. Shift the cassette on the sensor
at the patient positioning end (backwards when looking from the keyboard). connect the low
voltage power supply connector P5. Power on. Push either +mm or -mm button to switch on the
positioning lights. If a fuse blows, check the lamps and their wirings. If not take step 13.

l) Using the keyboard drive one motor at a time. (HOLD, LAYER, CASSETTE, PRIMARY
APERTURE). If a fuse blows, check the last motor operated and its wirings. Replace if
necessary. The rotation motor cannot be driven separately and it must be checked last. Push
READY and wait till cassette stops. Keeping the power on move manually the rotating part off
from it’s start sensor, after which the system automatically tries to return the rotating arm onto the
sensor, driving the rotation motor only. Check. If everything is normal take step 14.

m) Enter the service mode. Select for 60 kV and 2 mA and try one exposure. If still OK, select for
maximum values and try one exposure. If still OK enter normal mode and try one normal
exposure with maximum values. If still OK the problem actually was a bad fuse that had blown for
no reason or a bad connection on one end of the connectors. Check. If a fuse was blown during
the exposures the tube power generator takes too much current for some reason and must be
replaced. In this case fuses should not blow but an error indication should appear. Check the
ratings of the fuses.

5 FLAT BATTERY
The equipment has two different types of parameter memories. The most critical parameters that
are seldom changed are stored into an EEPROM-type memory that is non volatile but the
amount of changes made is restricted to about 10’000 times per single data.
The other parameters that are not fatal if lost and which are altered more often are stored into a
battery backup RAM-type memory on the keyboard processor board. This information is lost and
substituted with minimum or less harmful ones if the battery goes flat.
When the equipment is powered on the battery is charged. A completely flat battery will be fully
charged within about two hours. If the equipment is never switched on or just shortly after long
intervals as may be the case when stock keeping it, the battery will last at least two months.
When the equipment is turned on with a flat battery the clock display and mm display are blinking
all zeroes. In the following is explained, which information is lost and with which values it is sub-
stituted.

LOST INFORMATION SUBSTITUTED INFORMATION

Calendar clock All zeroes
Layer position 00
Exposure counters All zeroes
kV value last used 60 kV
mA value last used 04 mA
Cephalostatic exposure time last used 0.2 sec (cephalostatic models only)
Cephalostatic soft tissue wedge position Position 00 (cephalostatic models only)
Up/down motor on one end limit Assumed to be not on an end position if not on
sensor
Automatic return mode Automatic return off
kV, mA pair select mode (AUTO) Individual settings
Temple rests open/closed Assumed to be open if not on sensor
Panoramic/Cephalostatic version Panoramic

After detecting this kind of a situation the substituted information must be corrected by resetting
the above listed parameters to actual ones.

CAUTION There are two parameters that must be corrected in order to gain the normal operation!

If the equipment was a cephalostatic one it must be once again programmed to be cephalostatic
as it is explained in the chapter “Panoramic/cephalostatic setup” on page B-15.
The correct place of the layer positioning motor must be learned into the system by driving the
motor in service mode twice past its reference sensor till the mm display ceases blinking. Take
care not to drive the motor into the mechanical ends that may cause damage.

I FUNCTIONAL DESCRIPTION

1 MECHANICAL CONSTRUCTION AND OPERATION

The equipment is attached to the column with steel cables and bearing brackets. The motor
placed in the upper end of the column moves the equipment up and down along the column.
Inside the column there is a counterweight which compensates the weight of the equipment. The
counterweight and the equipment are connected to each other with steel cables through pulleys
so that the movement of the counterweight is double related to the movement of the equipment.
Therefore the weight of the counterweight is only one half of the weight of the equipment.
The equipment itself consists of the Z-carriage and the rotating unit. The upper horizontal part of
the Z-carriage (upper support arm assembly) supports the rotating unit and contains mechanics
determining the kinematics of the rotation movement. Low power supply with mains filter is also
placed in the upper support arm assembly.
The vertical assembly of the Z-carriage contains the guidance wheels and pulleys of supporting
cables. Mains switch, fuses and Hall detectors for up/down movement are also located in this
assembly.
The lower horizontal assembly (lower shelf assembly) of the Z-carriage contains patient support
mechanism, keyboard and keyboard processor.
The rotating unit consists of three main assemblies: rotating part, tube head assembly and film
cassette mechanism. The rotating part includes the rotating motor with gears, generator proces-
sor and x-ray generator. The tube head assembly contains the collimator / primary slot mecha-
nism, and the cassette mechanism contains the secondary slot.
The remote control switch is connected to the equipment with a cable.

1.1 Rotational mechanism

The rotating mechanism is designed so that the x-ray beam passes the patient’s teeth and tem-
poro-mandibular joints in an optimal way throughout the excursion.
The geometry of the driving groove of the block (Fig. 3, 4) is as follows. The groove has the
shape of a curve of a circle symmetrically to both directions from the center the driving groove to
± 25° turning angle (point A being the center of the circle). From ± 25° turning angle to ± 85° turn-
ing angle, the radius of the shape of the groove varies and reminds of an evolvent curve. There-
after the groove follows the tangent of the curve.

I-2 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter I - FUNCTIONAL DESCRIPTION

The rotating unit (Fig. 2, 7) is attached with bearings to the upper horizontal part by means of a
cam (Fig. 2, 1). For both axles of the cam there are two angular contact ball bearings (Fig. 2, 2)
which are preloaded without clearance by means of nuts (Fig. 2, 3).
The cam has two main tasks: Firstly, it transfers the weight of the rotating unit to the main block
(Fig. 2, 4) through bearings. Secondly, it determines the path of the bearing point B during the
rotating cycle. Apart from point B, the path of the rotating movement is also determined by drive /
guide point C. On the main block (Fig. 2, 4) there is a U-groove and a guide wheel (Fig. 2, 5) rolls
along the inner edge of the groove. The bearing point of the wheel is fixed in relation to the rotat-
ing unit (Fig. 2, 7). There is also a driving wheel (Fig. 2, 6) which is concentrically located in rela-
tion to the bearing point. The fixing point of the driving wheel (transmission) is located so that the
driving wheel can move unhindered crosswise in relation to the groove.
The mechanism has a loading spring (Fig. 2, 8) which forces the driving wheel against the outer
edge with great pressure.

Chapter I - FUNCTIONAL DESCRIPTION

1.2 Cassette mechanism

The primary function of the cassette mechanism is to enable controlled linear movement of the
film cassette across the radiation beam synchronically in relation to the rotation movement.
Besides, the cassette mechanism has certain secondary functions such as secondary slot which
prevents the radiation scattering from patient from exposing the film and Frankfort positioning
light reflector which produces a horizontal light beam to facilitate patient positioning.
The assembly (Fig. 3, 1) is the frame of the cassette mechanism. A carriage (Fig. 3, 2) is
attached with bearings and axles (Fig. 3, 3 and 4) to the frame. The panoramic carriage is locked
to the frame.
The cassette holder (Fig. 3, 5) is attached with linear bearings to the carriage through axle (Fig.
3, 6) and support wheel (Fig. 3, 7). The cassette carriage is driven by an friction wheel (Fig. 3, 8)
which is in contact with the top surface of the carriage.
The lateral force caused by the cassette holder, the weight of the film cassette and the loading
spring of the driving wheel is compensated by a support wheel in the carriage (Fig. 3, 2). The
cassette holder rolls against the support wheel. The secondary slot (Fig. 3, 9) is attached to the
carriage (Fig. 3, 2). Commanded by the microprocessor a stepper motor (Fig. 3, 10) rotates the
friction wheel analogically with the rotation mechanism through worm gear transmission.
The cassette mechanism is shown below

1.3 Tube head

Tube head tank itself has got no serviceable parts and must always be returned to the factory for
repair.
For changing tube head see section“CHANGING THE TUBE HEAD” on page H-7.

1.4 Collimator/primary slot mechanism

The collimator tube (Fig. 4, 1) is attached with screws to the radiation window frame. Under a nut
there is an inner primary slot sheet which consists of an aluminium filter plate and lead plates
with holes. The lead plate reduces the radiation beam for the actual primary slot. The aluminium
plate filters the harmful soft radiation. In the outer part of the collimator tube there is a second
inner primary slot (Fig. 4, 2) which reduces secondary radiation scattering from the inner parts of
the collimator tube.
Part (Fig. 4, 3) is the frame of the primary slot mechanism. The primary slot (Fig. 4, 4) is attached
to a slot carriage (Fig. 4, 5) which is attached with bearings to the frame. The stepper motor
draws the slot carriage through a screw (Fig. 4, 6) and a nut (Fig. 4, 7). The drive nut has a plate
which together with an optic sensor (Fig. 4, 2) composes the place reference for the primary slot.
The microprocessor controls the stepper motor. Motor commandment is described in section
“Motors” on page I-10.
The function of the PCB 105-10-08 is described in section “Circuit boards” on page I-8.

Chapter I - FUNCTIONAL DESCRIPTION

1.5 Positioning mechanism

The fixed frame of the mechanism is the installation plate (Fig. 5, 1), to which the mobile frame is
attached with linear bearings through axes (Fig. 5, 2). All parts entering into contact with the
patient, i.e. patient handles, chin and/or bite support/s (Fig. 5, 3 and 4) and temple supports (Fig.
5, 5) are fixed to the frame (Fig. 5, 6) so that they move together with the frame.
Linear movement is driven by a stepper motor. Primary drive is realized by cogged belt and sec-
ondary drive by a screw. The screw is connected to a drawing nut (Fig. 5, 7) attached to the
frame (Fig. 5, 6). The adjustment of the linear movement position reference is realized with a
Hall-detector. The detector is located on a PCB card (Fig. 5, 8) and the magnet is located on a
bar attached to the installation plate (Fig. 5, 1). The microprocessor controls the linear move-
ment.
The cranks (Fig. 5, 8) of the temple supports are attached with bearings to the frame (Fig. 5, 6)
so that they can rotate freely. The movement of the cranks is synchronized to each other with
gearwheel quadrants. Clearance of the quadrants is adjusted with an adjustment piece (Fig. 5,
9). The force closing the temple supports is produced with a spring. The force is transferred to
the quadrant through lugs (Fig. 5, 10). The force opening the temple supports is produced with
the step motor to a lever (Fig. 5, 11) through a drive screw (Fig. 5, 12) and a drive nut. The lever
transfers the force over to the temple supports through an adjustment screw. The limit switch is
the Hall detector on the PCB card (Fig. 5, 7). The detector gets an impulse from a magnet
located on the lever (Fig. 5, 11). The microprocessor commands the movement of the motor. The
function of the command system is described in section “Circuit boards” on page I-8.

1.6 Height adjustment mechanism

The vertical part of the Z-carriage is supported to the groove of the column (Fig. 6, 1) with 8
wheels. Sideways it is supported with wheels (Fig. 6, 15). There are four more wheels (Fig. 6, 11)
in 90 ° angle. In vertical direction the carriage is supported by wires through pulleys (Fig. 6, 12).
In the upper part of the column there is a top trim cover (Fig. 6, 28) to the lugs (Fig. 6, 22) of
which pulleys (Fig. 6, 27) are attached with bearings.
A direct-current motor (Fig. 6, 44) draws the drive pulleys through a worm gear transmission (Fig.
6, 10). In practice only one of the two pulleys is closely connected to the secondary axle of the
transmission whereas the other is freely assembled with bearings. This means that one of the
two cables (Fig. 6, 4) moves the Z-carriage while the other cable only partially carries the weight
of the Z-carriage. One cable would be strong enough to carry the Z-carriage in case the other
should break.
The counterweight (Fig. 6, 2) compensates the weight of the Z-carriage. Cables are connected to
the counterweight through a compensating lever (Fig. 6, 7). The compensating lever compen-
sates small differences in length of the cables and ensures that both cables can carry the weight
of the Z-carriage. The counterweight is attached with four wheels (Fig. 6, 5) to the tracks of the
column.
A Hall detector in the vertical part of the Z-carriage is the limit switch for the Z-carriage move-
ment. The detector gets impulses from magnets (Fig. 6, 32) of the column. Commandment of
height adjustment motor is described in section “Motors” on page I-10.

Chapter I - FUNCTIONAL DESCRIPTION

2 ELECTRICAL PARTS AND THEIR FUNCTIONS

The electronics of the equipment consists of the tube head, ten printed circuit boards, six motors,
three lights and the cables connecting these parts to each other. These parts are located in the
equipment itself and in following it is explained where they are and what are their functions.

2.1 Tube head

The tube head is located at the other end of the rotating part.The function of it is to convert the
high frequency power, supplied by the generator circuit board, into X-rays. The high voltage
transformer and cascade circuit board in the tube head rectify and multiply this power to a maxi-
mum of 80 kV DC to the X-ray tube which in turn generates the radiation. The metal case gives a
radiation-proof hermetically closed housing to the X-ray tube. Because of the high voltage
needed by the tube, the tube head is filled with transformer oil to give successive insulation. The
tube head inner parts cannot be serviced in the field, because the opening of it needs extra clean
environment and after opening the oil must be dried in vacuum, but the tube head temperature
sensor is located in the center of the connector P1 and can be replaced without removing the
tube head.
When the tube head is replaced it must be correctly aligned and the tube type must be given to
the system, after which the system must be allowed to learn the filament characteristics.

2.2 Circuit boards

There are nine circuit boards in the equipment. In the following their locations and functions are
described as well as the actions that should be taken when replacing one. Also the on board fuse
ratings are marked.

CAUTION When connecting or disconnecting cables and/or circuit boards the power must be
switched off and a 10 second time must be allowed to the capacitors to discharge. Other-
wise damage can be caused to the circuit boards.

CAUTION To avoid damage caused by static discharge always discharge yourself by touching the
earthed metal frame before touching the electrical parts.

Cascade circuit board (105-10-01)

This circuit board is in the tube head multiplying the high voltage to the X-ray tube. It cannot be
seen or serviced in the field, because the opening of the tube head needs extra clean environ-
ment, vacuum pumps etc.

Tube power generator (or simply generator) (105-10-02)

This circuit board is in the horizontal section of the rotating part, nearest to the tube head. It’s
function is to generate the X-ray tube filament power and the high frequency AC power to the
tube head high voltage transformer.
When this circuit board is replaced the jumper settings and fuse ratings must be checked to
match the ones of the faulty circuit board. Be sure that the voltage selection is the same than on
the LOW VOLTAGE POWER SUPPLY circuit board.
J1 selects the inverter operation voltage range (110 = 90 V - 130 V; 220 = 190 V - 265 V)
J2 selects the control circuitry operating voltage and must be set accordingly to J1
J3 selects the tube filament voltage range (C = Comet tube; T = Toshiba tube)
F1 is the main fuse (8AT for 190 - 265 V; 15AT for 90 - 130 V)
F2 protects the current inrush limiting resistor R1 and is always rated 1AT
F3 is the mains transformer fuse (250 mAT for 190 - 265 V; 500 mAT for 90 - 130 V)
F4 is the inverter end stage fuse and is always rated 8AFF (Superfast)
F5 is the inverter end stage fuse and is always rated 8AFF (Superfast)
F6 is the control circuitry secondary fuse and is always rated 1AT
F7 is the filament circuitry secondary fuse (3.15 AF for Comet; 4 AF for Toshiba)

CAUTION Always turn off the mains switch before handling the board because the mains voltage
comes onto this board. Always allow at least two minutes of time to the capacitors to dis-
charge after the power has been on.

I-8 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter I - FUNCTIONAL DESCRIPTION

Generator processor (105-10-03)

This circuit board is located beside the generator in the horizontal section of the rotating part.
This is the circuit board that is nearer to the cassette end of the rotating part. Its function is to
control the generator and to operate three stepper motors, the rotating part rotation motor, the
film cassette transportation motor and the tube head primary aperture motor. It also operates the
tube head cooling fan and the cephalostatic solenoids when applicable.
When this circuit board is replaced, the new one must be adapted to the system. This circuit
board contains information about the primary aperture positions as well as the X-ray tube type
and filament characteristics. Therefore the primary apertures must be aligned and the tube type
must be programmed, after which the system must be allowed to learn the filament parameters.
F1 protects other circuits than the stepper motor drivers on this board and is rated 1AT

Cassette limits (105-10-04)

This circuit board is located in the cassette end of the rotating part. It’s function is to detect the
end limits of the cassette motor movements and pass the information to the generator processor
through a 20-pole flat cable.
When replaced, the four Hall-detector magnet adjustments are to be checked.

Low voltage power supply (105-10-05)

This circuit board is located in the upper fixed part. It supplies power to all of the electronics
(including lamps) in the equipment and has the main secondary fuse on it. If the equipment is
completely dead and the fuses near the mains switch are OK this is the place to look at.
When replaced, the operating voltage jumper and the primary fuse must be checked to match the
ones of the faulty circuit board.
Voltage selection: The jumper can be installed into four positions to adjust the operating voltage
range (100, 110, 220, 240 V) The equipment operates at this voltage ± 10% with full load. Be
sure that the selected voltage range is similarly selected on the TUBE POWER GENERATOR
circuit board.

F2 Mains primary fuse (500 mAT for 220 V and 240 V; 1 AT for 100 V and 110 V)
F3 Main secondary fuse 4 AF
F4 Layer positioning light fuse 2.5 AT
F5 Sagittal positioning light 2.5 AT

CAUTION Make sure that the power is switched off before handling the board to avoid electrical
shock and unnecessarily blown fuses if some live parts touch the frame.

Keyboard processor (105-10-06)

This circuit board is located in the lower fixed part. It is the master microprocessor that controls
everything in the equipment. It operates three motors, the up/down motor, the layer adjust motor
and the patient temple rest motor. It also controls the operation of the generator processor and
gives the operation commands to it via one serial communications cable. It operates the two
relays on the low voltage power supply that give power to the generator and to the lamps. The
keyboard and display are also controlled by this processor.
When this circuit board is replaced, the new one must be adapted to the system. This circuit
board contains information about the warning signal pitch, up/down motor speed settings, layer
adjust motor location and zero point, operational parameters (kV, mA, sectors, layer forms etc.),
the exposure counters and the time. Also the error history and previous technical factors memo-
ries go along with this circuit board. There are two things that MUST be done before use when
this board is replaced:
In the service mode pass twice the layer motor reference sensor to find the place.
Tell the system whether it is a panoramic or a cephalostatic one.
F1 protects other circuits than the motor drivers on this board and is rated 1AT

Layer/hold limits (105-10-07)

This circuit board is located at the layer adjust mechanism in the lower fixed part. It’s function is
to detect the layer adjust motor and the temple rest motor limits and pass the information to the
keyboard processor via a 6-pole cable.
When replaced the layer adjust and temple rest motor operations should be checked.

Primary position detector (105-10-08)

This circuit board is located at the inner side of the tube head, above the collimator. It detects the
reference point of the primary aperture mechanism and passes the information to the generator
processor via a 3-pole cable.
When this circuit board is replaced or even moved from it’s place the primary apertures must be
aligned. It is impossible to “put it back to the very same place”, because it should be repositioned
with an accuracy of 1/100 mm.

Display/keyboard (105-10-09)
This circuit board is located in the keyboard housing below the lower fixed part. It’s function is
rather obvious, to drive the displays according to the information it receives from the keyboard
processor and to pass the information of the keyboard states to the keyboard processor via a 6-
pole cable.
This circuit board can be replaced without any further actions.
F1 protects the circuits on this board and is rated 1AT

2.3 Motors

There are six motors in the equipment that perform all the movements needed. In the following is
explained where the motors are, what they do, where they get their driving power from and what
is the system how they are operated.
Five of the motors are stepper motors the operating method of which is different from the DC-
motor. They have two coils with two wires to each and the current is flowing through the coils in
both directions in turn with a phase difference that causes the rotation. Now, if the stepper motor
is wrongly connected or one or two wires are broken the motor might run not at all, run with low
torque, run to wrong direction, change the rotation direction by itself or run at double or half
speeds. To check this the coil resistances should be about 5 ohms each and one coil connected
to connector pins 1 and 2 and the other to pins 3 and 4. If it runs to wrong direction just reverse
one coil polarity. Reversing both causes nothing. Measuring the voltages needs an oscilloscope
because the motors are driven by about 40 kHz switch mode current regulated power supplies.
Best to have a reference motor with or to cross connect two motors to check the driver circuit
operations. If cross connecting, remember that the limit sensors operate wrongly.

Up/down motor
The up/down motor is located on the top of the column. It’s function can clearly be seen, it is
moving the actual X-ray part in vertical direction along the column. It is a DC brush motor with a
worm gear of 1:72 and it gets it’s drive from the keyboard processor first downwards along the
spiral cable (on the left side seen from the front) and then upwards along a cable located inside
the column.
When this motor is activated, it is first driven one second slowly and then accelerated softly to full
speed. When the button is released the motor stops immediately if it was still in the slow mode,
but slows down softly if it was running faster. If the motor is driven to the end of it’s traverse path
(limit sensor) the system performs a quick stop by using the motor as a brake (short circuit). The
motor speed is controlled with pulse width control at 200 Hz frequency, that can be heard as a
humming sound.
The slow speed can be adjusted independently to both directions to fulfil all needs.

I-10 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter I - FUNCTIONAL DESCRIPTION

When the motor is driven to the limit sensor and stopped, it will not start to that direction but only
to the other. When started to the other direction it will run slowly as long as it gets back to the
sensor and over it. To avoid hazards the system will speed up the motor if it doesn’t reach the
sensor within 5 seconds when the button is kept pressed, that normally is long enough, and
ignore the sensor pulse. Therefore it should be noted that if for some reason the up/down move-
ment is driven over the limit sensor and cannot be driven back within this time (jammed) the but-
ton should not be operated more than 4 seconds at a time while helping the motor by hand. If this
is not taken care of, the system detects the sensor as if it was the sensor of the other end and
never comes to the normal operating range.
In this case enter the slow speed adjustment mode to the direction you want to go and press the
button. This mode ignores the sensor and enables you to reach the normal range between sen-
sors. While in the normal range exit the adjust mode and then drive the motor to the other end
sensor to get it operative again.

Layer adjust motor

This motor is located at the layer adjust mechanism in the lower fixed part. It’s function is to move
the bite block, temple rests and handles (and the patient) horizontally in order to get the patient’s
teeth in the right position relative to the layer positioning light. It is a stepper motor and it gets it’s
drive from the keyboard processor.
When this motor is activated, it will first drive one second at a slower speed and then accelerate
to the full speed.
When it reaches one end of it’s movement range it will slow down and stop in the end. When the
operating button is released the motor stops immediately.When the motor is moving, it’s coordi-
nates are updated in the mm-display. They are calculated from the motor steps and show the
position relative to the sharp layer (00) that is programmed during the alignment procedure. The
position of the sharp layer relative to the motor movement range varies and is not the same for all
equipment. For this reason the movement is not always from -30 to 09 but can be somewhat dif-
ferent. Still the full range is always 39 mm.
The motor has one reference sensor on the LAYER/HOLD LIMITS circuit board. Every time
when the sensor is passed to the positive direction the position information is checked and cor-
rected if necessary. If the layer adjust mechanism or the keyboard processor is replaced it may
happen that the motor is not driving in correct range and cannot be driven past the sensor to find
the reference point.
To solve this the system in the service mode does not stop the motor at the point it considers to
be the mechanical end but continues at slow speed to enable you to drive it past the sensor in
positive direction (to be sure pass it first in negative direction). Care must be taken not to drive
the motor to the mechanical stop that may damage the gears.

Temple rest motor

The temple rest motor is located beside the layer adjust motor. It’s function is to keep the patient
centered in the right position during the exposure and release the patient after the exposure. It is
a stepper motor and it gets it’s drive from the keyboard processor.
When the motor is activated the system checks with a sensor on the LAYER/HOLD LIMITS
board whether the temple rests are open or closed. If the sensor is active (near the magnet) it is
detected as a closed position and the motor is driven into open direction a certain length. If the
sensor was passive the motor is driven into closed direction as long as it finds the sensor. Note
that opening is performed at full speed but closing is done more gently not to startle the patient.

Rotation motor
This motor is located in the rotating part beside the generator processor board. It is rotating the
rotating part during the exposure and return. The drive to this stepper motor is delivered by the
generator processor.
÷This motor cannot be operated independently but is activated by the system whenever the rota-
tion is needed. The operating range of the rotation is controlled by two sensors fixed to the rotat-
ing part frame.

Technical Manual Planmeca Proline CC panoramic x-ray I-11

Chapter I - FUNCTIONAL DESCRIPTION

The rotation start sensor defines the starting point (home position) of the rotating arm. When
pressed READY the system will continuously seek for the sensor and rotate the arm to it if it was
pushed aside. Note that if the arm was pushed over to wrong side of the sensor (not towards
center) the system tries to find the sensor by rotating the arm but in wrong direction. In this case
the arm must be pushed over the sensor to the actual operating range and thus enable the sys-
tem to find the sensor.
The rotation end sensor is polled in the end of the rotation. The rotation must stop on the sensor,
otherwise an error is generated. If the sensor was reached and gone over the rotation is stopped
immediately with an error.

Cassette motor
The cassette motor is located on the top of the cassette holder in the cassette end of the rotating
part. It drives the cassette holder (and the film cassette) linearly across the X-ray beam during
the exposure and back during return. In cephalostatic models it also takes care of opening the
secondary slot wide enough and of moving the soft tissue wedge. It is a stepper motor and it gets
it’s drive from the generator processor.
The operating range of this motor is controlled by four sensors on the CASSETTE LIMITS circuit
board. Two of them control the position of the secondary aperture (cassette holder carriage) and
two the end limits of the cassette holder movements.
When driven to READY position the motor is operated till both the cassette holder and the cas-
sette holder carriage start sensors are active. If the cassette is pushed aside the system will seek
back for the sensors. When driven to the end direction normally a certain length is driven and no
sensors are used. The exception is when the equipment is powered on with the cassette not on
the start sensors. Then the cassette is driven all the way till it finds the end sensor of the cassette
holder.
In panoramic models the end sensor of the cassette holder carriage is never used. It is used
together with the end sensor of the cassette holder to detect the right position of the secondary
aperture when in cephalostatic mode.

Primary aperture motor

This motor is at the inner side of the tube head fixed to the collimator. It changes the primary
aperture to the selected one. The drive to this stepper motor is delivered by the generator proc-
essor.
The positioning of the primary apertures must be very accurate and is done with an accuracy of
1/100mm. To achieve this the final adjustment in the alignment procedure must be performed in
the same direction than they are driven when the apertures are changed (+). To avoid the inac-
curacies caused by clearances the apertures are always changed in this one direction and when
it is necessary to move into the other direction a calibration sequence is performed. Also when
the equipment is powered on the calibration sequence automatically takes place.
For calibration the system uses the PRIMARY POSITION DETECTOR circuit board with an infra-
red slot detector. The motor is first driven towards the sensor till it activates, after which the
speed is slowed down. The movement is continued a certain length to allow the clearances and
the sensor hysteresis. The motor is reversed with slow speed till it comes off the sensor, which is
the calibration position. The motor is driven to the desired aperture (always 0 after power on).
When driving from one position to another the system calculates the distances in between and
uses a certain speed profile to minimize the time but still reach the final position at minimum
speed for maximal accuracy. The aperture number display is blinking while the motor is running.
When not in use (not calibration sequence) the slot detector is powered off to prevent it from
aging that might affect the performance. In service mode it is though always on to make it easier
to make measurements.

2.4 Lamps

To make it as easy as possible to position the patient rightly, three positioning lights are provided.
All the lights are similar in construction and each of them has an individual fuse on the LOW
VOLTAGE POWER SUPPLY circuit board. The lamps are 6 VAC 10 W halogen bulbs with spe-
cial filament form. The light beam adjustment is done by bending the mirror rather than moving
the bulb and therefore the bulb replacement does not necessarily need the adjustment proce-
dure. It is good practice though to check the adjustments.

I-12 Planmeca Proline CC panoramic x-ray Technical Manual

 Chapter I - FUNCTIONAL DESCRIPTION

Focal trough positioning light

This lamp is located under the lower fixed part cover. It is reflecting a narrow light beam vertically
to the face of the patient in order to indicate the horizontal layer where the imaging is at the
sharpest. The power to this lamp comes from the low voltage power supply through the keyboard
processor. The lamp is fused with a 2.5 A slow blow fuse at the low voltage power supply board.
This is the most critical of all the lamps, because without this lamp there is no indication of the
actual sharp layer place.

Midsagittal positioning light

This lamp is located in the upper fixed part. It is reflecting a narrow light beam vertically along the
center line of the patient’s face to help the centering of the patient. The power to this lamp is
coming from the low voltage power supply circuit board, where is a 2.5 A slow blow fuse provided
individually for this lamp.

Frankfurt positioning light

This lamp can be found in the cassette end of the rotating part. It reflects a narrow horizontal light
beam on the left cheek of the patient. It’s vertical position can be altered by hand to correspond
the patient’s characteristics. The purpose of this light is to help to position the patient’s head to
be horizontal. The power to this lamp comes from the low voltage power supply circuit board,
where there is a 2.5 A slow blow fuse for it.

2.5 Wiring

The whole electronics of the equipment is constructed in order to keep the amount of wires at
minimum and especially minimize the wires at such points where they are subject to wear due to
movement etc.
The equipment wiring diagram (105-02-01-1/1-B) illustrates the whole wiring concept. It can be
seen that through the most critical rotating joint goes only seven wires that carry all the power
and information that is needed. The accurate information about each wire or cable harness can
be found from this wiring diagram or from the separate cable harness drawings that the reference
numbers on the diagram point to.
In the following few aspects are covered to give an overall view to the wiring concept.

Mains cables
The mains cables are tried to keep separate from all the other wires as good as possible. In the
220 V and 240 V equipments, where the currents are smaller the mains comes in along a spiral
cable on the right side of the column (front view). It ends up to the mains fuses and mains switch
that are located on the lower fixed part on the other side of the metal wall than the keyboard proc-
essor.
In 100 V and 110V equipments the thicker mains cable comes straight to this lower fixed part and
fuses.
From the mains switch the mains cable goes up to the upper fixed part and a mains filter. After
the filter it goes to the low voltage power supply that generates the operating voltages to the elec-
tronics.
Through a relay on the low voltage power supply the mains continues through the rotating joint to
the tube power generator circuit board that is in the rotating arm. Note that the relay only discon-
nects one of the mains wires and therefore even when the power is not connected to the genera-
tor by this relay the electrical shock hazard remains, depending on the polarity of the mains plug.
Always use the mains switch to disconnect both wires.
The mains filter in the upper fixed part takes care that no disturbances generated by the genera-
tor are allowed to the mains. Still there is a small filter on the generator circuit board, the purpose
of which is to cut off the very high frequency components that might be coupled to the low voltage
wires that are squeezed near to the mains wires when going through the rotating joint.
From the main switch on the mains cables are thick enough to be used also in the 100 V equip-
ments.

Technical Manual Planmeca Proline CC panoramic x-ray I-13

Chapter I - FUNCTIONAL DESCRIPTION

Protective earthing
In the 200 V equipments, where the mains comes in at the bottom of the column, the first earth-
ing is done there. From there it continues along the mains spiral cable to the lower fixed part,
where it is connected to the lower fixed part. In 100 V equipments the first earthing is done here.
From this point the vertical part is earthed by a separate wire. The earth wire continues also to
the upper fixed part, where it is connected to it and also to the mains filter. From this point on the
earthing wire proceeds through the rotating joint and is connected to the rotating part near the
bearing. This is the very point, where the ground of the electronics is connected to the protective
earthing. From this point goes one more earthing wire to the tube head.

When servicing the equipment always take care that all the earthing wires are properly con-
nected. If the earthing is not in order the equipment can be lethal to the user.
The microprocessor detects if the ground of the electronics is not connected to the protective
earthing (tube head not earthed) and will not start the generator, but it cannot tell if the earthing is
not connected to the mains plug.

Electronics power supply

To keep the wire count down there are only two operating voltages delivered along the cables.
One is 6VAC to the lamps and the other is an about 33 VDC voltage that is supplied to the circuit
boards. Them both have the same ground. The circuit boards have small separate switch mode
power supplies that generate from the 33 VDC the voltages needed on each circuit board. For
example the generator processor alone needs voltages of +33VDC, +15VDC, +5VDC, -5VDC
and -15VDC. The system operates normally if the 33 VDC remains between 26 VDC and 39
VDC thus allowing a good tolerance for the mains voltage variations and voltage losses in the
cables.
The layer positioning light, having such a long cable from the power supply, has a separate
ground wire not to affect the keyboard processor ground levels.
The generator circuit board needs the mains for the power stage but also two floating power sup-
plies for the control circuitry and the tube filament. Again, to save the wires the generator has a
small mains transformer on board to create these voltages from the mains.

Signals
To be able to minimize the wires two microprocessors were installed, both as near as possible to
the generator, motors and sensors. To pass all the information needed to operate the equipment
there is only one wire that connects the microprocessors together providing a serial communica-
tions channel. The keyboard/display is connected to the keyboard processor with a three wire
serial link and needs thus only five wires (actually six with double ground). The keyboard alone
should otherwise have needed 29 wires.

From the keyboard processor leaves a seven pole spiral cable down the left side of the column.
Two of these are needed for the up/down motor that couldn’t possibly be placed near to the proc-
essors. The other five wires go to the remote control box. Three of these are needed for the nor-
mal operation of the equipment and the two others provide one extra serial communications
channel to allow various kinds of new functions and equipment to be adapted to the equipment.
In the following are shortly described the signals in various interconnecting cables that can easily
be checked. The rightmost columns define the voltage range and type of the signal:
