1.1 Safety
Please be sure to observe the warnings and safety information listed in this
service manual.
They are specially labeled as CAUTION, WARNING or DANGER:
Nonobservance may result in minor physical injuries or material damage and
malfunctions.
Nonobservance may lead to serious physical injury or death.
Immediate danger to life and limb. Threat of serious physical injury or
death.
1.2 Operation notes
1.1
bеЦдблЬ
Rated line voltage The volume tomograph GALILEOS functions in the following
rated line voltage ranges:
z 200 – 240V
z 50/60 Hz
The permissible line voltage fluctuation is ±10%.
The internal line impedance must not exceed max. 0.8 Ω.
Only permanent electrical connection of the system is allowed in Germany.
Remote control The system can be equipped with...
z a 1 - 3 m coiled cable with release button inside the treatment room or ...
z a remote control with or without coiled cable located outside the X-ray
room (see installation instructions).
Warm-up time After it is switched ON, the system requires a warm-up time of approx. 1 min.
Self-adjustment routine At the same time, a mechanical and electronic self-adjustment routine is exe-
cuted. If a key is pressed during the self-adjustment routine, an error message
will display on the Easypad.
Cooling period The cooling period between two exposures is maintained by an automatic
exposure blocking function according to the pulse/pause ratio. The decrementing waiting time count is displayed on the Easypad.
Turn-off time The turn-off time must amount to at least 30s.

Demo units If the volume tomography unit is to be presented as a demo unit at trade fairs
or exhibitions, it must be ensured that radiation release is blocked (see "Demo
mode – Operation without radiation release" on page 1-6).
Software version The overall system software version is determined by the software statuses of
the EEPROMs on the boards (see "List of software versions" on page 1-10).

implosion hazard, a small amount of beryllium, a lead lining as well as mineral
oil.
Help messages are displayed on the control panel.
Proceed according to section "1.11 Removing the covers".
When removing covers, always remember that direct sunlight or bright room
lighting can cause system malfunctions due to activated light barriers.
Therefore: avoid direct sunlight and bright room lighting above the unit!
Reattach the covers.
When attaching the covers: be sure to screw the sheet metal cover back on.
IMPORTANT: For reasons of electromagnetic compatibility, be sure to fasten
all screws.
Select the correct current/voltage type and adjust the measuring range to
match the expected readings.
Perform continuity tests only on units which are switched off.
If several exposures with radiation must be taken to check a measurement,
make sure that the prescribed cool-down intervals are observed. They are
maintained by an automatic exposure blocking function (see operating
instructions).
The pulse/pause ratio is 1: 20, i.e. a
20 second pause is maintained for each second of radiation cycle. The pulse/
pause ratio is automatically maintained (automatic exposure blocking).
It is essential that you observe the radiation protection regulations applicable
in your country prior to radiation release.
The test rotations triggered by pressing the T key on the Easypad and then
the release button are executed without radiation.

Tab 1 1.2 Operation notes
When replacing parts Switch the unit OFF before replacing parts.
For safety reasons the power supply should be switched off at the junction
box of the building installation when replacing parts around the line transformer.
Please always wear an ESD wrist band to protect sensitive components on
printed circuit boards (ESD).
Always check the system and adjust it as required after replacing a board or
the X-ray tube assembly.
The article numbers for ordering spare parts can be found in the spare parts
list, Order No. 61 25 699. The diagrams contained in the spare parts list provide a useful guide when replacing parts.

For demo use, the "X-ray detector dummy for GALILEOS" (order no. 61 19
007) should be used instead of the actual X-ray detector. For further information, please refer to the instructions included with the dummy.
1.3.1 Switching the demo mode ON
When operated in demo mode, the unit must not release any radiation. For
this reason, you must take the following safety measures:
z Switch the unit OFF.
PERILOUS SHOCK HAZARD. It is essential to switch the unit off and to
wait at least another 1 minute before taking off the covers of the X-ray
tube assembly.
1. Remove the cover of the tube assembly.
2. Loosen screws A and remove cover plate B.
3. Set dip switch S2 (DX6) to position 2.
If switch S2 is not set to position 2 before switching off the unit, various error
messages will display when the unit is turned back on.

6. Switch the unit ON and check the mode with the info screen.
Demo mode: ON means that: The demo mode is switched ON (Radiation
release is not possible)
Demo mode: OFF means: The demo mode is switched OFF (Radiography, X-ray radiation are possible!)
z Switch the unit OFF again and reattach cover plate B and the tube
assembly covers by following the dismantling procedure in reverse order.

The software can be upgraded or downgraded to the desired version.
This update mode is required e.g. if a replacement component delivered
out of stock has a newer status than the prevailing overall system status.
In this case, a main version update to the overall system status (displayed

SW Update Manager
10. Reboot the system.
It is always necessary to reboot the system after any software update
.
(The new DX11 version can run only after the system is successfully rebooted;
see also Section 6.11, "Replacing circuit boards".)
Any errors with the consecutive numbers 01, 03, 04, 06 and/or 07 displayed
immediately following the software update may be ignored. If these messages
appear again after the system is rebooted, please carry out troubleshooting as
described in section 2.5.
If any conspicuous problems occur in connection with system handling after
the software update has been completed, please repeat the software update
immediately.
Checking the program versions 11. Check whether all modules contain the current program version via the
SW Update Manager or Service routine S008.2 (see page 5-35).
Modules that are connected and the program versions of which correspond to the current main program version are identified by a continuous
green bar.
Modules that are not recognized by the system are identified by a broken red bar.
If the actual status of the module could notbe queried for the update, then
V00:00 is displayed for the SW actual version.
If there is a hardware incompatibility for the program version to be newly programmed, or if the module contains a newer software version than what is offered in the update file, this is identified by a red triangle with exclamation
mark.
If the version of the selected update file is lower than the current software version of the system, nothing is displayed in the right-hand window. The downgrade required in this case is possible only via the MAIN VERSION mode.
12. Select the "Extended details" via SIXABCON.
This generates a XML file (with the system parameters) which is filed under the network name of the system in the PDATA/P2K_Config folder (see
also section 1.7 on page 1-17).
