1. Introduction
Dear BETA User!
The new XENOTEST BETA LM presents you with a state-of-the-art light exposure and weathering
equipment for obtaining vital information about the long term behaviour of your products when exposed
to the influences of weather, and solar radiation in particular, using the time acceleration effect. The
optimum conditions for an accelerated laboratory test are created by simulating the natural influencing
factors and simultaneously intensifying important parameters at sample level.
Important hints

1.2 Safety hints
• Operating the system presupposes knowledge of this manual. The operating manual should be
kept close to the unit.
• For work at and with the unit the user needs instructions in his mother language based on the
operating manual (FRG: UVV VBG1 § 7 (2)).
• The XENOTEST BETA units shall only be used for the exposure and weathering of materials in
the intended areas of application .
• For the functioning of the water circuits and the humidity system the unit has to be leveled by its
height adjustable feet.
• Before starting the unit ensure that the necessary requirements for a failurefree operation of the
unit are given. Observe the installation requirements in chapter 2.2 of this manual as well as
valid national laws, regulations and guiding principles.
• Inflammable or explosive materials at temperatures below 150 °C must not be inserted into the
unit.
• Do not insert materials which despite their application as directed release toxical substances.
• Disconnect the system from the mains before carrying out any maintenance work, e.g. exchange
of lamps, cleaning, emptying the water tank (remove the safety contact plug).
• The lamp is switched off when the test chamber door is opened. The lamp must be re-ignited to
continue testing once the door has been closed again.
• The lamp is switched off when the casing lid on the upper side of the unit is opened. The lamp
must be re-ignited to continue testing once the casing lid has been closed again.
• Within the stipulated proof intervals, or at least once a year, the door safety switch and the
safety device of the upper casing lid have to be proved for their safety function.
• Within the stipulated proof intervals, or at least once a year, the temperature cut-offs of the
humidifier, lamp supply, heating system and the lamp exhaust air have to be proved for their
safety function.
• Within the stipulated proof intervals, however at least once a year, the water level indicator
switch of the water tank and the humidityfier have to be proved for their safety function.
• Within the stipulated proof intervals, or at least once a year, the carousel switch of the water

• The cable of the lamp contact plugs are provided with numbers. It´s absolutely necessary to
ensure that the lamp contact plugs are connected to the corresponding lamps (fig. 25).
• Under extreme conditions, especially at high temperature exposures lamps, specimens,
specimen holders and sensors heat up considerably during the weathering tests. Protective
gloves must therefore be worn when removing them to prevent injury to your hands. This applies
in particular to high temperature tests.
• Because of exhaust air temperatures up to 120 °C max. the hoses of lamp and test chamber air
outlets must be of flexible and heat resistant material.
• The maximum length of the exhaust air hoses of lamp and test chamber including two 90° ben-
dings is limited to 3 meters. With longer exhaust air hoses or more than two 90° bendings an
external blower is required.
• Overheating may occur if air inlets or outlets are obstructed. Please ensure that the necessary
space is available (fig. 1).
• The unit has to be switched off when carrying out any maintenance work. Turn the main switch to
position "0" and pull mains plug. Secure against reconnection to the mains.

test chamber.
4.1.3 Water tank (fig. 5)
The water tank is placed in the bottom part of the
apparatus and provides for the supply with ultra-
pure water for the humidity and rain functions (see
fig. 11 water circuits).

2 Aperture for hose connections
3 Inlet socket
4 Outlet socket
5 Water level indicator
Water quality
The water quality must be of high-grade purity to
prevent deposits building up on the optical
filter system, the internal walls and the
samples. Deposits will alter the exposure
results. The use of ion exchange cartrid-
ges alone is not sufficient.
Regarding the water purity we refer to the mini-
mum requirements of some important standards,
such as DIN 53387 „Light exposure and weathe-
ring of plastics“:
1. Electrical conductivity: < 5 µS/cm
2. PH value: 6-8
3. Content of solid bodies < 1 ppm measured
as silicon dioxide
Maintenance
4.1.2 Test chamber (fig. 6)
The test chamber becomes accessible after un-
locking the test chamber door and swinging it to
the side. It is equipped with a safety switch allo-
wing to switch off the machine during a running
program.
This safety switch must be checked for its
perfect technical function within the deter-
mined inspection intervals, or at least once
a year.
Are located in the centre of the test chamber the
selected outer cylinder (1) with the three xenon
lamps (2) and the filter lantern (3).
The 16 sample holders (4) are latched into the
two carousel racks (5) and during operation rota-
ted around the lamps and the filter lantern.
Test chamber and xenon lamps are supplied by
separate air flows. A uniform air ventilation over the
specimen surface is achieved by an appropriate air-
flow above and below the specimen carousel (fig.
10 ventilation scheme). At the bottom rear of the
test chamber two connection hoses are provided
which supply the two humidifiers with air. The ma-
ximum chamber humdidity can be adjusted up to
95% r.h. depending on the preset temperature.
The rain bars (6) mounted in the test chamber
spray ulra-pure water in cyclical intervals and with-
out any pressure from the water tank on to the spe-
cimens (7). The bars can be withdrawn from the
test chamber by pressing on the unlocking base
(8) at the bottom end of the rain bar. A so-called
XENOSENSIV sensor (9) is installed on a samp-
le holder by means of a special adapter to measu-
re the irradiance in the range between 300-400nm
and the black standard temperature in the surface
temperature range up to 130°C. If no sensor is used
the end plug must be fitted.
A sensor is mounted in the upper rear part of the
test chamber which measures the test chamber
temperature and the relative humidity. The sensors
combined with the program control guarantee con-
trol of constant setting values.

of the current program.
The interface (3) on the right-hand side of the main
switch provides for the data output and external
computer control.
Right to the test chamber (4) is the climatic duct
(5) with the integrated heating (6) to warm up the
test chamber air. The two air flap motors (7) serve
to adjust the air flaps in the ventilation duct (8).
The climatic fan (9) recirculates the air and is
controlled by the climatic fan control (10).
The operating hour counter (11) counts the
operating time of the equipment.
The three power supply units (13) of the lamps
are placed behind a protective wire mesh (12).

The fuse for the heating (14) and the fuses for
the three lamps (15) are located below the
protective wire mesh. The fuse protection for the
three lamps is 25 amps and for the heating it is 16
amps.
4.3 Apparatus top (fig. 8)
The separate exhaust air flows for lamp cooling and
test chamber warming are evacuated at the top of
the unit via separate exhaust air sockets to the open
(see fig. 11 ventilation scheme). Exhaust air sok-
ket lamp cooling (16) diameter 100mm, exhaust
air socket test chamber warming (17) diameter
200mm.
The hoses for the lamp and test chamber
exhaust air must be made of flexible heat-
resisting material, as the temperatures of
the exhaust air may reach up to a max. of
120°C.
The max. length of the exhaust hose is li-
mited to 3m including the option of two 90
degree bends. In case of longer exhaust
air ducts or with more than two 90 degree
bends an external blower is needed.

(fig. 9)
The fan to cool down the lamps (1) is seated
below the test chamber. At the same level on the
left side the two humidifiers (2) are fitted. The
water supply to the two humidifiers can be adjusted
by means of a valve (3). Via two fexible, heat
resistant hoses (4) the humidifiers are supplied
with air out of the test chamber and direct the
humidified air via 8 outlets (5) to the ventilation
duct. From there the humidified air is inserted to
the test chamber by means of a fan (see fig. 11
ventilation scheme).
The sensor for the test chamber temperature and
the rel. humidity transmits the actual values taken
from the exhaust air flow of the test chamber to
the program control system. With a target/actual
comparison the requested test parameters are
adjusted permanently by adjusting aggregates.
With an inserted XENOSENSIV sensor (see fig.
6.9) a slip ring collector (7) transmits the
measured values to the program control. The rain
pump (8) provides the three rain bars with pure
water.
The inlet and outlet lines of the humidifier, the
water return line from the test chamber and the
supply line of the water pump are led through the
top of the water tank (9).
The ignition units (10) in conjunction with the
power supply units ignite the xenon lamps.
