Introduction
This section details the corrective maintenance for the Orthoralix
9200 systems.
In general, the defective part is located by means of diagnostic
messages, self-test information or by the principle diagrams.
In the event of electronic defects, repairs are made by replacing
one of the following exchangeable units:
t UVCFIFBE
t PQFSBUPSDPOUSPMQBOFM1$
t DPOWFSUFSCPBSE12
t IPTUDPNQVUFSCPBSE1$
t QPXFSTVQQMZCPBSE1/

If the converter board PQ1 or the tubehead need
to be replaced, the service programs Tube calibra-
tion and Vf tube editing must be performed (see
the relevant paragraphs of this section for more
information)
If the host computer PC1 needs to be replaced, re-
member to remove the EEPROM D38 from the old
board and mount it on the new one, otherwise all
the following parameters will be lost:

In the event of mechanical or motor defects, the following as-
semblies can be replaced:

Do not move the Z-carriage along the column
when the system is off:doing so it could damage

Diagnostic messages
While the Orthoralix 9200 system is running, a number of mes-
sages may be generated on the display, to warn the operator
of equipment irregularities or to indicate that some fault has
occurred.
In the latter case a diagnostic message will help to find the
fault.
The meaning of each message is given, together with an expla-
nation about the electrical circuit involved with the defective
function.
If more than one alarm is detected, the first one acknowledged
is displayed and the others are stored: by pressing the RESET

the alarms acknowledged.
F.3.1
Over temperature
This alarm indicates that the temperature measured over the
power transistors (by a PTC sensor) of the converter board has
exceeded the limit (>80° C).

the alarm, temporarily disables the converter electronics and
communicates the alarm to the host board PC1.
The host provides a diagnostic message on the display and
waits for the alarm to self-reset before starting a new exposure
sequence.
