with respect to extremities, in case of operation errors:
o between patient table and patient tabletop
o between patient table and catapult Bucky
o between patient tabletop and handle of the Bucky
o between patient tabletop and base frame in tabletop movement
o between tube unit and object/floor when moving the tube unit down
o between tabletop and 3D ceiling support when raising or
lowering the tabletop
o between bottom edge of the tabletop and object in table downwards move-
ment
o between persons, MULTIX unit, VERTIX Bucky wall stand, wall or objects and

Safety Information
o between handles of the 3D ceiling support and the collimator when rotating
the collimator
o at collimator accessory rails
Please take special care when the patient is getting onto or leaving the patient
table that no unintentional activation of the operating elements occurs.
If the patient slips, for instance, it is possible that the table brake may be activated unintentionally, or the active brakes are overridden and thus a system movement occurs.
Warning
The patient and operating personnel may grip only the handles which are inten-
ded for this purpose. If this is not possible, please pay attention to posssible
risks of injury by crushing between moving parts and their guide openings.
The operator is obliged to ensure that system movements are released only if
it is assured that neither the patient nor third parties can be endangered by
these movements.

(1) Actuate the left or right (1) foot kick switch in the tablebase to release the
table brakes. This enables the tabletop to be moved in the longitudinal and
transverse direction.
The function of the switch can be programmed by the Siemens Uptime Service:
o Foot kick switch in "Push-button mode" ("Deadman switch")
The table brakes are released only as long as the switch is actuated.
o Foot kick switch in "Switch mode" ("Sensor switch")
– If the foot kick switch is actuated only one time, the table brakes will be
released. The second time it is actuated, the brakes will be locked again.
If the table brakes are not actuated this second time within a certain time
(time-out time), then the brakes will be locked automatically.

Momentary-contact switches
Example: MULTIX TOP ACSS-P (the different control panels and collimators are described in the
following)
The 3D ceiling support and X-ray tube unit are positioned by the user directly and
manually.
u Use the handles (5) to rotate the X-ray tube unit about the vertical telescopic
axis (+154° to -182°) or about its own horizontal axis (± 120°), thus ensuring
that the X-ray tube is moved in the desired direction.
– Click stops in the vertical axis: every 90°
– Click stops in the horizontal axis: at 0° and ± 90°
u The longitudinal (354 cm), transverse (222 cm) and vertical (150 cm) travels of
the 3D ceiling support with X-ray tube unit are also performed manually using
the handles (5) to ensure that the X-ray tube unit is moved in the desired
direction.
B
u Like "brake release" push button (4) on the control panel, momentary-contact
switches "A" or "B" on the left or right handle release the vertical movement of
the X-ray tube unit on the telescopic column.
– The momentary-contact switches are programmable, i.e. can be set only
for "SID brake" actuation or for "floating" travels as well.
The "floating" travel can in addition be programmed by the SIEMENS Uptime
Service (except for the configuration TOP manual without planigraphy):
– During slow movement over click stops, either to stop or not to stop,
as well as
– "with" or "without" alarm.

Warning
Do not exert downward force on the 3D ceiling support if its vertical movement
is blocked! If necessary, it may, however, be moved upward if a continuous
clicking noise can be heard.
Please contact your Siemens Service representative immediately. This is
important, since the main cables may be defective or a spring might be broken.
Such a defect would then mechanically block the downward travel.
Warning
In order to prevent collisions, all longitudinal, transverse or vertical travels and
rotations of the 3D ceiling support must be executed concurrent to manual
guidance of the 3D ceiling support by the operator. Especially important in this
regard is the residual braking distance of the 3D ceiling support following
actuation of the brake switch. This point must be taken into consideration in
order to prevent collisions with persons or objects.

We recommend to perform this check on a regular - e.g. monthly - basis.
If the SID values are incorrect, overexposures might occur.
Please notify our Uptime Service if this is the case.
SID checks which are performed on a regular base will prevent unintentional
overexposures.
For ACSS systems with or without planigraphy the following applies:
The system can be programmed for "metric" SID and "metric" cassette formats
by service. If inch-format cassettes are inserted no ACSS mode, and hence, no
automatic format limitation will be activated..
This also applies to the reverse case, i.e. if the system is programmed for the
"inch" format and cassettes with a "metric" format are inserted.
In this case, mixed operation using both "metric" and "inch" cassette formats is
not permissible!
Is the system programmed for mixed operation, mixed operation using both
"metric" and "inch" cassette formats is permissible.

For ACSS systems with or without planigraphy the following applies:
The system can be programmed for "metric" SID and "metric" cassette formats
by service. If inch-format cassettes are inserted no ACSS mode, and hence, no
automatic format limitation will be activated
This also applies to the reverse case, i.e. if the system is programmed for the
"inch" format and cassettes with a "metric" format are inserted.

In this case, mixed operation using both "metric" and "inch" cassette formats is
not permissible!
Is the system programmed for mixed operation, mixed operation using both
"metric" and "inch" cassette formats is permissible.

Operating modes of the follow-up control 0
There are four different operating modes of the follow-up control:
o Manually controlled motor-driven height adjustment of the tube unit
o Automatic height follow-up of the tube unit to the VERTIX TOP
(horizontal projection)
➩ Refer to the VERTIX TOP Operator Manual.
o Automatic control for constant SID on the MULTIX table (vertical projection)
o Automatic control for constant SID on the VERTIX TOP (vertical projection)
➩ Refer to the VERTIX TOP Operator Manual.
o On selection of the tomographic mode (planigraphy), the 3D overhead support
is moved automatically (if programmed that way by the Technical Service) into
the “Planigraphy” starting position that can be programmed by the Technical
Service. The associated table height must be actuated by operating the foot
kick switch. The automatic “Table height stop” then takes place at the table
height determined for planigraphy and thus corresponds to the intended SID
for planigraphy.

Operation
Manually controlled motor-driven height adjustment of
the tube unit
Function 0
o Manual operation of the push button in the control panel of the 3D ceiling
support for tube unit upwards or downwards movement releases the brakes
of the vertical movement of the tube unit and moves the tube unit on the 3D
ceiling support by motor drive in the required direction.
o The set radiation direction has no influence on the control of the motor-driven
height adjustment of the tube unit. The radiation direction can thus be freely
selected.
o Motor-driven total vertical movement 1480 mm (± 10 mm)
(unless limited by the Technical Service on customer preference)

Operation
– It is possible to release automatic switch-on of the light localizer with
LASER line light localizer on the collimator when operating the push button
for motor-driven tube unit upwards or downwards movement, if so
required. In this case the Technical Service can activate this programmable
function.
– Automatic end shutdown protects the tube unit upwards or downwards
movement if the tube unit on the 3D ceiling support has reached the upper
or the lower end position.
– During the installation of the system it is possible to determine a selectable
stop position for a SID value of 102 cm or 115 cm.
If the tube unit reaches the predetermined SID value when moving, then
the motor-driven movement is ended.
– The tube unit moves on in the required direction only after pressing a push
button for tube unit upwards or downwards movement once again.
o Prerequisites for the motor-driven height adjustment of the tube unit:
– Push button for motor-driven tube unit upwards or downwards
movement pressed
– No overhead support end position reached
– No collision protection has responded
– No EMERGENCY STOP switch operated
Warning
Please pay attention to collision-free movements of the 3D ceiling support
with tube unit and collimator, to protect patients and objects
against damage.

Operation
o The automatic collision protection is a safety device for protecting the
patient.
Function:
– If during motor-driven movement of the 3D ceiling support with tube unit
and collimator a collision occurs in the downwards direction, a force of not
more than 200 N becomes effective to protect the patient and objects.
– On response of the automatic collision protection, a brief acoustic signal
sounds as alarm to the operator.
– The motor-driven movement is then immediately ended.
– After pressing the push button for the motor-driven upwards movement or
manually, after releasing the vertical brakes, the tube unit on the 3D ceiling
support can be moved again out from the collision zone, also by motordriven lowering of the patient tabletop.
– For the protection of the patient and objects, the automatic collision protec-
tion is also effective in the upwards direction, if for instance the 3D ceiling
support with tube unit and collimator is moved under the patient table of
the MULTIX table or other objects such as a sickbed etc. A force of not
more than 200 N becomes effective in the collision.
– On response of the automatic collision protection, a brief acoustic signal
sounds as alarm to the operator.
– After pressing the push button for the motor-driven downwards movement
or manually, after releasing the vertical brakes, the tube unit on the 3D
ceiling support can be moved again out from the collision zone.
o To assure patient rescue in the case of a power failure with braked 3D ceiling
support, the tube unit on the 3D ceiling support can be pushed manually with
a force of 200 N out from its braked position.
o The motor-driven movement of the tube unit is not possible if:
– The EMERGENCY STOP switch is actuated or
– “Planigraphy” is selected
– On double operation of the upwards/downwards movement
– With released vertical movement
o The EMERGENCY STOP switch on the MULTIX table switches all motor-driv-
en movements off when it is operated.

o As long as the criteria are not yet fulfilled, the lamp of the push button
(MULTIX constant SID) beneath the two control lamps for the operational
status in the MULTIX table flashes.
➩ Criteria see e.g. paragraphs "Automatic end shutdown of the MULTIX con-
stant SID control ..." and "If the SID is less than 50 cm ..." on page 27.
o The lamp of the push button (MULTIX constant SID) beneath the two control
lamps for the operational status in the MULTIX table lights up constantly only
when the criteria are fulfilled.
o The SID set on selection becomes effective and is kept constant when the
table height changes, in that the 3D ceiling support with tube unit automatically tracks correspondingly.
o During the motor-driven movement of the table lift, the lamp of the push
button (MULTIX constant SID) beneath the two control lamps for the operational status in the MULTIX table flashes.
