ORTHORALIX 9200 Service Manual
F.4 Service programs
F.4.1 General
The Orthoralix system incorporates diagnostic service software
programs, which can be run either by the operator for routine
machine checks before use, or by the service engineer to assess
system operations before taking corrective maintenance action.
F.4.2 Test start up
The service program procedure is started by pushing together
the DUMMY RUN and PATIENT SIZE keys when switching on the
machine: the keys must be kept pressed till the message WAIT
disappears from the display.
The following message will appear on the display:
SERVICE PROGRAMS
Pls press Y- Y+
where Y- and Y+ are keys S16 and S17 on the keyboard (used to
move the rotating arm along the Y axis, to center the patient with
respect to the lateral vertical light).
By pressing the above mentioned keys, you can select the desired
service program.
To return to normal operations, switch off the system.
F.4.3 Test procedures
The service programs consist of several selective tests, each in-
dependent from the others.
The test sequence is as follows:
F.4.3.1 X movement test and adjustment
By selecting this service program you can check the functioning of
the X 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:
-X- TEST & ADJ.
+0 +0 XYRABC

ments :
- 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
has not been activated.
There are three different tests:
1.
Constant speed test.
By pressing the 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 the 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,
Be careful during these two tests that the electrical
the mechanical end stop with the step motor still
rotating.
3.
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 relevant 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 need to change the start posi-
tion of the X movement after having checked the system with the
image quality phantom (see the paragraph "Verify the centering
of the system with the image quality phantom" in this section).
F.4.3.2 Y movement test and adjustment
By selecting this service program you can check the functioning
of the Y 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:
-Y- TEST & ADJ.
