1 Description of instrument
1.1 Description
Designation: SPECTRO XEPOS
Model: XEP05
Type: 76004852
1.2 Function
X-rays excite the atoms of the sample, causing them to emit radiation. This
radiation is measured by a semiconductor detector.
To achieve a higher sensitivity, the exciting radiation can be optimized by using X-
ray optical elements or filters.
The instrument comes with a prepared analysis method. Data are already stored
in the instrument's memory. The measured values are compared with these data.
After the measurement is complete, the results of a sample relating to an unknown
composition are displayed on the screen.
The sample material may be solid, liquid or in powder form, see Chapter "How to
measure different samples".

Safety
SPECTRO XEPOS — 19.01.2017 — 13
2.2 User information
Compliance with all safety instructions is mandatory. It's for your own safety.
Carry out only operator maintenance work that is described in chapter 6. The
operating personnel is not permitted to proceed with any other maintenance
work. Any further services (e.g. technical maintenance) or repairs must only
be performed by service personnel that are authorized by the manufacturer.
Comply with all safety instructions and accident prevention regulations at all
times while operating and maintaining the instrument. This regulation is, for
example, DIN EN 61010 or any other comparable national standard.
The safety measures must be checked following every technical maintenance
or repair activity. This check must be performed according to VBG4/DIN EN
61010 or a comparable national standard.
Compliance with the maintenance schedule specified by the manufacturer is
mandatory, All maintenance activities must be recorded. This will maintain the
operational safety of the instrument.
Never tamper with the safety devices! If you feel that a safety device does not
work properly, shut down the instrument immediately! Please contact your
Service Center.
Only genuine spare parts must be used when repairing the instrument. The
use of non-genuine spare parts will make the CE Declaration of Conformity
null and void.
The instrument may only be connected to the power supply with a protective
grounding conductor.
If an instrument is positioned on a sloped surface, it may roll away during the
operation. Secure the instrument while in operation. This applies also when
the instrument is being transported.
Compliance with the relevant safety regulations when using tools and
operating equipment is mandatory.
Compliance with the safety instructions when handling and preparing the
samples (material safety data sheet) is mandatory. The contact with certain
metals, plastics, powders, liquids, or other materials can be hazardous to
health.
2.3 Intended use
The spectrometer must only be used to analyse liquid substances or powdery
materials inside special containers (e.g., cuvette, sample cup). Solid samples, e.g.,
metal parts, may be analyzed outside of these containers.

Safety
— 14 SPECTRO XEPOS — 19.01.2017
2.4 Prohibited operating conditions
Do not operate the instrument if one of the following conditions exists:
If the instrument is faulty or damaged.
If the ambient conditions do not comply with the specification.
2.5 Residual risks
This instrument has been manufactured in accordance with the state of the art.
Nevertheless, a residual risk cannot be completely excluded.
Danger! Risk of electric shock!
The spectrometer produces electric voltages of up to 60 kV.
Shut down the instrument immediately if damaged.
Caution! Danger of poisoning!
The ray exit window of the X-ray tube and the detector window contain beryllium.
Vapors or dust of beryllium and its compounds are toxic and hazardous to your
health when inhaled.
Do not touch this window.
Should you have broken the beryllium window of the detector, immediately
seal off the measurement window of the spectrometer with adhesive tape.
This ensures that no broken beryllium window pieces can leave the
spectrometer. Switch off the spectrometer and inform the service department
of SPECTRO. The detector and the spectrometer can no longer be used.
Caution! Risk of crushing injuries!
When closing the sample chamber lid, there is an inherent risk of crushing injuries.
When closing the sample chamber lid keep the fingers out of the sample
chamber.

Safety
SPECTRO XEPOS — 19.01.2017 — 15
Caution! Ionizing radiation!
This spectrometer operates with ionizing radiation (X-rays). The safety devices
ensure that the spectrometer can be operated only in a safe, closed and shielded
condition.
Never tamper with the safety devices.
If you are concerned that the safety devices do not work properly, shut down
the spectrometer immediately. Please contact your Service Center.
The results of the ambient dose rate measurements are an integral part of the
documentation supplied with the spectrometer (radiation protection
certificate).
The condition of the beam stop (it cannot be seen from the outside since it is
immediately in front of the X-ray tube) is shown by the combination display
"Beam-Stop / X-Rays ON".
"Green" indicates that the Beam Stop is on, "Red" indicates that the Beam
Stop is open. If the Beam Stop is opened, this always caused the sample
chamber lid to be locked. An orange-colored LED indicates the operation of
the X-ray tube. See also Chapter 5.1.2 on page 24.
Note
If the instrument is in its normal operating mode (standby or measuring mode), it
produces ionizing radiation (X-rays).
The safety circuits in the instrument are designed to ensure the sample chamber
lid is always locked during the measurement.
For your safety, the safety circuits are checked automatically. Therefore, when
starting the software, a message is displayed requesting the opening and closing
of the cover (referred to as Start-up test, see Chapter 5.3).
Automatic safety circuit checks must be carried out at least once a month. If the
device has not been switched off and switched on again at the main switch for one
month, the software prompts you to do so (see also chapter 5.3.4). Three days
before the deadline, a first reminder appears in the status display of the software.
