own protection and for avoiding damage to the unit.



Use the unit solely for its intended purpose.



The unit is intended for use in dry and dust-free rooms

where there is no risk of explosion.



Prior to connecting the unit to the mains power supply,

ensure that the protective conductor of the power supply
unit is correctly connected to the protective conductor of
the mains power supply network. The mains power plug
may only be plugged into a mains power socket that is
equipped with a protective conductor. Do not eliminate
this protective effect by using an extension lead without a
protective conductor.



Ensure that the mains voltage that is stated on the type

plate of the unit matches the mains voltage of your power
supply network.



When setting the unit up, ensure that the mains power

switch and the device plug are freely accessible. Ensure
also that the venting slots of the unit are not covered or
blocked.



Do not connect any devices to the unit other than the

ones that are intended for this purpose.



Attention: Disconnect the unit from the power supply

prior to loosening, replacing, or removing any of the ca-
ble connections!



Do not start the unit if the mains power cable or the unit

itself are damaged.



Switch the unit off after using it. Continuous operation is

not permissible. The maximum runtime per day is
10 hours. It is not a syfety risk if you the tube for longer
intervals but this could reduce the lifetime of the tube.



Start the unit at least twice per year and check its safety

functions. The tests that are included in the checklist at
the end of this document must be performed.
If damaged, the unit must be returned to the manufac-
turer for repair. Only the manufacturer or a certified com-
pany that has been appointed by the manufacturer are
authorised to repair and maintain the unit.



Since X-ray units generate dangerous radiation that is

hazardous to health, only trained and qualified persons
are authorised to start the X-ray unit in accordance with
the local, country-specific rules and regulations.



In Germany: When working with the X-ray unit, the man-

datory measures and duties that are outlined in the Ger-
man X-ray ordinance (Röntgenverordnung, RÖV) must
be strictly complied with.



The requirements of the certificate are to be followed



In particular, the operator must ensure that

the X-ray unit is protected against access by unau-
thorised persons;

the unit is not in use longer than necessary;

persons working with the unit do not remain in the
direct vicinity of the unit longer than absolutely
necessary.



The use of the unit is prohibited if

the sliding door that is made of lead-containing
acrylic glass and that is used for opening the ex-
periment chamber, or the other protective glass
windows that are used to observe the X-ray unit
and the experiment chamber, are damaged;

the fan at the X-ray plug-in side inside the unit is
inoperative (acoustic check);

the safety circuits for interrupting the X-ray opera-

tion when the sliding door is opened do not oper-
ate properly.



How to clean:

S-LOCK.

2 OPERATING

INSTRUCTIONS



The device fulfils the technical requirements that are

summarised in the current guidelines of the European
Community. The characteristics of the product entitle it to
bear the CE mark.



The unit must be used under the supervision of an expert
and in the electromagnetically controlled environment at

research, teaching, and training facilities (schools, uni-
versities, institutes, and laboratories).



This means that, in such an environment, radio transmis-
sion devices, e.g. mobile phones, should not be used in
the direct vicinity of the unit. The connected cables must
not be longer than 2



Electrostatic charges or similar electromagnetic phe-

nomena (HF, bursts, indirect lightning discharge, etc.)
may affect the unit so that it will not work within the
specified data range.
Occuring interfering signals may result in an automatic
shutdown of the high voltage during measurement! In
this case please follow section 6.6.
The following measures reduce or eliminate potential in-
terferences: avoid carpets; provide equipotential bond-
ing; perform the experiments on a conductive, earthed
surface; use shields and shielded cables. Do not use ra-
diofrequency transmitters (radio sets, mobile phones) in
the direct vicinity of the unit. After a total exit by actuating
the mains power switch, perform a reset.

This unit corresponds to class A of the standard DIN
EN 61326 and may be used without any restriction only in
non-residential areas. If - although the use of the unit is re-
stricted to special classrooms in a school or another training
facility - electromagnetic interf erences occur in the surround-
ing residential area, the operator can be required to take the
appropriate measures (e.g. shielding, long distance with re-
gard to sensitive equipment, short periods of use, use of the
shortest possible connecting cables, etc.) and to pay for
these measures.

3 INSTRUCTIONS OF THE GERMAN X-RAY
ORDINANCE

In Germany, the operation of the X-ray unit is subject to the
regulations that are outlined in the X-ray ordinance (Rönt-
genverordnung, RöV). In accordance with this ordinance, the
unit fulfils the mandatory requirements of an X-ray unit for
schools as well as those of a full-protection device.
In Germany, the operation of the unit is not subject to ap-
proval, but to reporting. Thus, report the unit to the appropri-
ate controlling institution.
For reporting, the test certificate and a copy of the design ap-
proval must be submitted to the responsible authorities. Only
specifically trained and instructed personnel is authorised to
operate the unit. When this unit is used as an x-ray device for
schools a radiation protection officer must be authorized.
If the unit operates at the maximum operating data, the local
dose rate at a distance of 0.1

m from the parts of the housing

that can be touched is less than 1

Sv/h.

Two independent safety circuits monitor the opening of the
sliding door that leads to the experiment chamber.
X-rays can only be generated when the sliding door is prop-
erly locked. The safety circuits also prevent the maximum
permissible operating values of the tube from being ex-
ceeded.
Do not use the device if the X-ray unit is manipulated in a
way that is not necessary for its set-up or for performing ex-
periments. It is absolutely forbidden to loosen the safety
screws of the sheet steel housing or to tamper with the win-
dows. Only the manufacturer is authorised to repair the unit.
For any operation of the unit outside of Germany, the appli-
cable local rules and regulations must be complied with.

5.2 Experiment chamber (

)

The experiment chamber (Fig. 4) includes the following func-
tional elements:

5.2.1 Sliding door (A)

Made of lead-containing acrylic glass. The door is perma-
nently monitored by a safety circuit and it is either locked or
released via an actuator.
For monitoring the position of the sliding door (open/closed),
two independent encoders are connected to the central
safety unit of the XR 4.0 X-ray expert unit. If the sliding door
is closed and the unit is in a safe state, the operator can lock
the sliding door via the control panel. The position of the ac-
tuator for this purpose is monitored by two additional inde-
pendent encoders that are also connected to the central
safety unit.
In order to open the sliding door,push it first against the stop
on the right-hand side.The S-Lock is now unlocked and the
door can be opened.
X-rays can only be generated when the door is locked.

5.2.2 X-ray outlet (B)

The X-ray outlet is located on the left-hand side of the ex-
periment chamber. It is used to hold metal tubes with circular
double-apertures for generating a beam of rays that is suited
to the experiment in question.

5.2.3 Socket panel in the experiment chamber (C)

Socket panel for the connection of devices that are located
inside the experiment chamber, e.g. a goniometer. The sock-
ets connect the devices either with the X-ray unit itself or they
lead to the external socket panel that is located on the right-
hand side of the unit (looping-through). This enables, for ex-
ample, the control or read-out from the outside of a digital
camera that is located inside the experiment chamber.

5.2.4 Working channel (D)

The working channel is located on the back wall of the ex-
periment chamber, at the bottom on the right-hand side. It

ends on the right-hand side outside of the unit and, thereby,
forms a connection through which, for example, a contrast
medium can be fed into the experiment chamber through
hoses during the operation of the unit. The shape and cross-
section of the working channel ensure that no X-radiation can
escape.

5.2.5 Optical bench (E)

An optical bench is fastened to the bottom of the experiment
chamber along the optical axis of the X-rays. The adapters
that are required for the experiments can be attached to, and
shifted on, this optical bench.

steel housing with a carrying handle, ready for use in the
X-ray XR 4.0 X-ray expert unit. The housing of the tube has a
catch lock and two safety contact pins that enable the tube
operation only if the plug-in unit has been installed correctly.

Fig. 6: X-ray plug-in unit on the left-hand side of the unit

The bay for receiving the X-ray plug-in unit is equipped with
coupling sockets and subsequent safety switches. These are
connected to the central safety monitoring system of the
XR 4.0 X-ray expert unit.

The following ready-prepared plug-in units are available:



Plug-in unit with a Cu X-ray tube



Plug-in unit with a Fe X-ray tube

order no. 09057-71



Plug-in unit with a W X-ray tube

order no. 09057-81

The plug-in units consist of a sheet steel housing with a fac-
tory-adjusted X-ray tube. In order to prevent them from over-
heating, the tubes are enclosed in a Duran glass cylinder.
This glass cylinder has side connecting pieces through which
forced air cooling via a fan in the XR 4.0 X-ray expert unit is
ensured.

The plug-in units also have an HV plug and a plug for the
tube cathode heating so that the operating values can be
taken over from the corresponding sockets of the XR 4.0
X-ray expert unit.
Make sure that the plug-in is inserted completely. Otherwise,
it is not going to work.

Handle the plug-ins with care!

6 OPERATION

This section describes the start-up of the unit and provides
an overview of its operation. Please read this section care-
fully in order to avoid problems or malfunctions.

6.1 Transport



Do not stress the drawer during transport. The device

should stand only on its feet.



During transport make sure that the sliding door is not

locked with the lock bar. If so, unlock the door using but-
ton IV, Fig 5 (switch on the device to use the button). The
door should not be open either - fix it with the S-LOCK.

6.2 Start-up

Connect the unit to the power supply via the supplied power
cable with an IEC connector. The socket for this purpose is
located at the back of the unit (see Fig. 9).

Fig. 9: Back of the unit with the socket for the power cable
and the central ON/OFF switch

6.3 Starting the unit

The central ON/OFF switch of the unit is located at the back
of the unit (Fig. 9). Actuate this switch to switch the unit on.
After the start, the unit will perform an automatic self-test
(safety test). For this purpose, the operator must open the
sliding door completely one time and then close it again. The
device status that is thus determined will be indicated on the
display unit in the control panel via the colours of the but-
tons IV and V.
In order to open the sliding door, push it first against the stop
on the right-hand side.The S-Lock is now unlocked and the
door can be opened.
If the unit had been switched off with the door being locked,
the door will be automatically unlocked once the unit is
switched on. The operator must then open the radiation pro-
tection door once and close it again (check of the safety cir-
cuit; described in the operating instructions and on the dis-
play unit).
If the X-ray plug-in is completely inserted and the door is
closed with the use of the SLOCK the left LED of button IV is
glowing in green. All other LEDs are enlighted in white. Now,
the unit is ready for use.
If this is not the case, contact the Service of PHYWE for help.

Caution:



It is only possible to lock the sliding door, if the

plug in with the X-ray tube is completely inserted
into the device.



if you switch off the device while it is locked you
have to switch it on again to unlock the door.

When used for the first time, the X-ray tubes should not run
at full power. Instead, we recommend letting the tubes run for
approximately 10 minutes at the maximum beam current, but
with an acceleration voltage that is limited to 25

kV maximum.

This procedure must also be repeated if a tube has not been
used for several weeks.

09057-99 / 2115

The unit has four device statuses that are listed in Table 2.
Depending on the status, the unit can be controlled entirely
via the buttons on the control panel together with the graphi-
cal representation.

6.5 Control via a PC with “measure”

As an alternative with regard to the direct control of the unit
via the control panel, the control of the unit and the represen-
tation of the measurement values can also be realised with
the aid of a PC and the “measure” software (14414-61).

6.6 Automatic shutdown of high voltage in case of fail-
ure

In case of interfering signals in the mains supply, the high
voltage will automatically be cut off in means to protect the
device from defects (introduced with firmware V

2.1). This

can be discerned by the fact that the x-ray tube stops to
gleam.
Running measurements eventually will not stop during the
shutdown, so they probably have to be restarted.
After removing the source of interference, check the door
status button IV and lock the door, if necessary (LED has to
be green). Afterwards, the device can be put into operation
again by pressing the X-ray button V. Thus, the high voltage
is switched on again and the measurement can be repeated.
If the device is controlled via a PC, the USB connection has
to be unplugged and plugged in, anew.

7 CHECKLIST

According to this list the device should be checked at least
two times per year:
1.  Check if the device shows any damage.
2.  All glass panes must be undamaged.
3.  Start the x-ray device according to chapter 6.1, 6.2 of this

operating instruction. Perform a functional test of the
status indications, e.g.:



Do all LEDs work porperly?



Is symbol „I“ enlighted in operating state 3 (Ta-

ble 3)?

4. Check all functionalities according to table 2 of this oper-

ating instruction:



In operating state 1 and 2 it is not possible to acti-
vate the x-radiation.



In operating state 3 the x-radiation is not active, the
door is locked.



Only in operating state 4 the x-radiation is active.

Does sign

appear on the screen (Fig. 11)?



If you activate the x-radiation with the following pa-
rameters: anode current 1

mA, anode voltage

kV, the x-ray tube should gleam brightly.

The device is only ready for use if the tests are performed in
the right way and successfully. Even if

only one

test fails the

device must not be used. Please contact the Phywe service
in this case. (service@phywe.com).
