ORTHORALIX 9200 Service Manual
F.4.3.17 80 kV limit.
With this service program you can limit (when required) the
maximum value of the kV generated at 80, instead of 84 and the
maximum value of the mA at 14, instead of 15.
The following message will appear on the display:
80 kV LIMIT Y/N
< NO>
1.
modify the condition (YES / NO) by pressing the keys projec-
tion+ or projection- on the keyboard.
2.
the new condition will be stored when the system is switched
off.
F.4.3.18 X-ray alignment
This service program is applicable only for Orthoralix 9200 DDE
versions.
By using this service program it is possible:
1.
to align the panoramic and transcan collimator respect to
the DMU digital sensor
2.
to align the ceph collimator respect to the secondary ceph
collimator and respect to the DMU digital sensor
3.
to make the conditioning of the X-ray tube, having the pos-
sibility to select kV, mA and exposure time and to make an
exposure without movements.
The following message will appear on the display:
X-RAY ALIGNMENT
Press DUMMY RUN to go
Then:
1.
for the panoramic and transcan alignment, please refer to
the paragraph
9200 DDE panoramic and transcan alignment) of this sec-
tion of the Service Manual.
2.
for the ceph aligment, please refer to the paragraph Ad-
alignment) of this section of the Service Manual.
3.
for the conditioning of the X-ray tube, please refer to the
paragraph
of the Service Manual.
4.
switch off the system to leave the service program.
F.4.3.19 Still ceph
This service program is applicable only for Orthoralix 9200 DDE
versions.
With this program you can have an X-ray emission with the param-
eters of the ceph technique, without having the ceph scanning;
the rotating arm and the ceph DMU (Digital Module Unit) can be in
any position (so it is not necessary to reach the reset position); the
READY LED on the operator panel is always ON, enabling always
the exposure even if the ceph DMU is not inserted.

This is useful whenever you need to have a ceph exposure with-
out movements (i.e. measurement of kV and mA, measurement
of the dose emitted).
The following message will appear on the display:
STILL CEPH
Press DUMMY RUN to go
1.
Press the DUMMY RUN key on the keyboard
2.
select the desired exposure parameters (kV, mA and s)
3.
make an exposure
4.
switch off the system to leave the service program.
F.4.3.20 Free exposure
This service program is not applicable for Orthoralix 9200 DDE
versions.
With this program you can have an X-ray emission with the param-
eters of the ceph technique, without having rotation; the rotating
arm can be in any position (so it is not necessary to reach the reset
position); the READY LED on the operator panel is always ON,
enabling the exposure even if the cassette is not inserted.
This is useful whenever you need to have an exposure without
rotation (i.e. centering the panoramic/tscan X-ray beam on the
secondary slit, measurement of kV and mA, measurement of the
dose emitted).
The following message will appear on the display:
FREE EXPOSURE
Press DUMMY RUN to go
1.
Press the DUMMY RUN key on the keyboard
2.
select the desired exposure parameters (kV, mA and s)
3.
make an exposure
4.
switch off the system to leave the service program.
F.4.3.21 Still panoramic
With this program you can have an X-ray emission with the param-
eters of the panoramic technique, without having rotation; the
rotating arm can be in any position (so it is not necessary to reach
the reset position); the READY LED on the operator panel is always
ON, enabling the exposure even if the cassette is not inserted.
This is useful whenever you need to have an exposure without
rotation (i.e. centering the panoramic/tscan X-ray beam on the
secondary slit, measurement of kV and mA, measurement of the
dose emitted).
The following message will appear on the display:
STILL PANORAMIC
Press DUMMY RUN to go
1.
Press the DUMMY RUN key on the keyboard
2.
select the desired exposure parameters (kV and mA)
3.
make an exposure
4.
switch off the system to leave the service program.
