Nominal line voltage
Remote control The unit may be equipped with a remote control to be used inside the
treatment room or outside of the X-ray room.
The release button with coiled cable can/must be removed from the
remote control and connected directly to the unit for testing.
Keep in mind that the disconnected cable may be the cause of defects.
Switch-on procedure
➢Switch the unit on.
ªIt will execute an electronic self-testing routine.
ªThe operational readiness indicator must be lit up.
Cooling period The cooling period between two exposures is maintained by an automatic
exposure blocking function according to the pulse/pause ratio.
Software version The DX4 board determines the software version.
You can find the software version with the following steps:
● Start service routine "2."
● A label next to the main switch includes an imprint of the software
version.
Disturbance of electronic equipment
caused by cell phones
To ensure safe operation of medical electrical equipment, the use of
mobile wireless phones in practice or hospital environments is prohibited.
CAUTION
No additional components on the support arm system
Attaching additional components to the support arm system is not
permitted.
Nominal voltage: 120V, 200V– 240V
Permissible fluctuation: ± 10%
Rated current: At 120 V: 10 A
At 200 – 240 V: 6 – 5 A
Nominal frequency: 50/60 Hz
Internal line impedance: At 120 V 0.3 ohms

not be disposed of as domestic refuse. This has been expressed using
the icon of the "crossed out trash can" since March 24, 2006, amongst
other methods.
Please observe the disposal regulations applicable in your country.
X-ray tube unit
The X-ray tube assembly contains a tube which can implode, lead lining,
and mineral oil.
Removing covers Observe the section on "Removing covers".
Measurements Observe the following when taking measurements:
● Always switch the unit off before connecting a measuring instrument.
● 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).
● Observe the radiation protection guidelines before releasing the
radiation.
1.4 Changing the device configuration
1.4.1 Changing the cone length
Explanation
If the cone length is changed, this change must be registered with service
routine S06 [ → 70].
1.4.2 Using and changing a diaphragm
Explanation
If a diaphragm needs to be used, this change must be registered with
service routine S07 [ → 71].

1.5 Measures when exchanging spare parts
Spare parts
The article numbers for ordering spare parts can be found in the spare
parts list, Order No. 62 34 111
Preparation
➢Always switch the unit off before replacing parts.
Replacement
The following must be observed when replacing individual
subassemblies:
● The unit must be disconnected from the power supply before
replacing any parts near the power supply, the power switch, or the
power supply board.
Disconnect the unit from the junction box of the building installation.
● Always wear an ESD wrist band to protect sensitive components on
printed circuit boards (ESD) and attach it to a ground conductor
(green/yellow).
● Always check the unit after replacing PC boards DX1 and DX4 or the
X-ray tube assembly.
● For safety reasons, the support arm must be secured with the safety
belt when replacing the X-ray tube assembly.
1.5.1 Safety-related tests
A protective conductor test and a leakage current test must be performed
prior to the installation or the hand-over of the unit as well as after repair
work.
See Sections "Protective conductor test [ → 63]" and "Leakage current
test."
NOTE
The diagrams contained in the spare parts list provide a useful guide
