ORTHORALIX 9200
Service Manual
There are three different tests:
(1)
Constant speed test.
By pressing keys mA+ and mA- on the keyboard, the step
motor is supplied so as to have a constant speed.
By releasing the key, the movement is stopped.
(2)
Variable speed test.
By pressing keys kV+ and kV- on the keyboard, the step
motor is supplied with a variable speed, starting from the
lowest and reaching the maximum. When the key is
released, the speed decreases from the speed reached to zero.

Modify the movement start position.
With this procedure you can modify the start position of the
movement via software, instead of by changing the actuator
of the corresponding optoswitch.
Pressing keys s+ and s- will change the number indicating
the start position (default = 0).
The correspondence between the number displayed and
the shift in mm is the following:
mm = 0.0728 X n displayed
This procedure is useful when you have to change the start
position of the Y movement after having checked the system with
the image quality phantom (see the paragraph "Verify
centering of the system with the image quality phantom" in this
section).
4.3.3. R movement test and adjustment
By selecting this service program you can check the functioning of
the R (rotation) movement (step motor, wiring and power supply
from the host computer board PC1) and change the relevant start
position of the rotating cycle.
The following message will appear on the display:
-R- TEST & ADJ.
+0 +0 XYRABC
where:
-
the first number indicates the actual position of the
movement with respect to the reset position - the second
number the correction introduced to modify the start position
of the movement
-
XYRABC the status of the optoswitches related to the
movements :
. X = start position of the X movement
. Y = start position of the Y movement
. RAB = start position of the rotation movement (2
optoswitches)
. C = start position of the cassette movement
If a capital letter is visualized (XYRABC) the related optoswitch
has been activated; if a small letter is visualized,the related
optoswitch has not been activated.

4.3.4. C movement test and adjustment
(1)
For Orthoralix 9200 / Plus / Ceph / DPI versions:
By selecting this service program you can check the functioning of
the C (cassette) movement (step motor, wiring and power supply
from the host computer board PC1) and change the relevant start
position of the rotating cycle.
The following message will appear on the display:
where:

the first number indicates the actual position of the
movement with respect to the reset position
-
the second number the correction introduced to modify the

-
XYRABC the status of the optoswitches related to the
movements :
. X = start position of the X movement
. Y = start position of the Y movement

If a capital letter is visualized (XYRABC) the related optoswitch
has been activated; if a small letter is visualized,the related
optoswitch has not been activated.
