F.3.47 DMU misplaced
This alarm message appears when the DMU is in the panoramic
position and the collimator is in one of the ceph positions.
To reset it, it is enough to move the collimator to the panoramic
or transcan position.
If the alarm message still persists, this can be due to one of the
following possible causes:
1.
one of the optoswitches S21, S22 or S30 (used to detect the
panoramic, transcan or ceph position of the collimator) is
damaged
2.
wiring of the connector X50(collimator)-X45(converter board
3.
If the converter board PQ1 needs to be replaced,
the service programs Tube calibration and Vf tube
editing must be performed (see the relevant para-
graphs of this section for more information).
F.3.48 DMU not present
This alarm message appears in one of the following conditions:
a)
the system is ready to make a panoramic\transcan exposure
but the DMU is not inserted in the panoramic bay
b)
the collimator is in the panoramic position but the DMU is
in the ceph bay.
To reset the alarm is enough to restore the proper working
condition.
If the alarm message still persists, this can be due to one of the
following possible causes:
1.
one of the optoswitches S21, S22 or S30 (used to detect the
panoramic, transcan or ceph position of the collimator) is
damaged
2.
wiring of the connector X50(collimator)-X45(converter board
3.
If the converter board PQ1 needs to be replaced,
the service programs Tube calibration and Vf tube
editing must be performed (see the relevant para-
graphs of this section for more information).

F.3.49 DMU not ready
This message appears on the display when the system is switched
on, during the booting time (duration about 30 s) of the Auxiliary
board PA7.
If after the booting itme the message is still present on the display,
the PA7 board is damaged.
the new PA7 by using the Service Programs (see
the relevant paragraphs of this section for more
information).
F.3.50 DMU busy
This message appears on the display when the system has ac-
quired an image but this image is not yet downloaded to the
personal computer.
If the alarms persists, check the connection between the auxiliary
board PA7 and the LAN network.
the new PA7 by using the Service Programs (see
the relevant paragraphs of this section for more
information).
F.3.51 CEPH collimator
The reset position of the secondary ceph collimator is detected
by the optoswitch S40.
When the secondary ceph collimator is in the reset position, this
position must be congruent with the reset position of the DMU
ceph bay, defined by the optoswitch S42.
If the optoswitch S42 is active (DMU ceph bay in reset position)
but the optoswitch S40 is not active, then the alarm Ceph col-
limator appears on the display.
Possible causes:
1.
optoswitch S40 defective
2.
wiring between optoswitch S40 and the ceph DMU interface
board PH3 connector X94 damaged
3.
check if the actuator of the optoswitch S40 is in the middle
of the optoswitch, when the secondary ceph collimator is in
the reset position; if not, adjust the position of the actuator
(for more details refer to the paragraph
collimator of this section of the Service Manual).
