Safety Instructions

1.4 General safety instructions

Safety instruments:

The Xenotest 440® is equipped with safety switches and temperature sensors which monitor the individual functions.

• If the chamber door is opened during operation, all functions are turned off

• A temperature switch monitors the build up of heat near the test chamber heater. All the functions are turned off if
the temperature exceeds 85 °C

• Safety temperature switches exist for monitoring the lamp cooling

• A float switch turns off all the functions as soon as the height of the water reservoir drops below a minimum filling

level

• If the xenon lamps are not ignited after three tries, the ignition process is aborted

After turning off due to an error, an interrupted test continues at the place where it stopped.

Incoming power connection:

The Xenotest 440 is connected to an incoming voltage of 400 V ± 10%, 50/60 Hz
The incoming power connection is made by a PE plug: (3P/N/PE) or (3P/PE) CEE (32A,5pol., 6h)

Disposal:

Requirements for the installation site

3.1 Room climate

Climatic requirements for the installation room:

In continuous operation the Xenotest® 440 can cause a
constant change in the room climate due to the emission
of warm air. Therefore, the instrument should only be

installed in an adequately cooled, dust-free room.

• Room temperatures of 18 °C to 25 °C

• Relative humidity of 50% (± 10%)

3.2 Room ventilation

The installation room must be equipped with a ventila­tion system that can accommodate a fresh air volume

flow of at least 300 m³/h.

• The fresh air must be filtered through an air filter of
filter class EU 4

• The installation room must be kept dust-free

3.3 Instrument exhaust air system

The lamp cooling of the Xenotest 440 must be connected

to an exhaust system. The exhaust system may be pro­vided by a contractor or direct extraction to the outdoors
whereby the following basic conditions must be satisfied:

• The exhaust air channel must be made of flexible,

heat-resistant material because the temperature of

the exhaust air can rise up to 120 °C

• The exhaust air channel may be a maximum of 3 m

long

• The diameter of the exhaust air channel must be

at least 100 mm. The connection nozzle on the Xe­notest 440 has a diameter of 100 mm

• The exhaust air channel may have a maximum of two
90° bends

• If greater lengths than 3 m or more than two 90°

bends are necessary for laying the exhaust air chan­nel, a blower must be installed by the customer

• The exhaust air system must work in such a way that

no air can be blown back into the instrument by back
pressure (see also Atlas price list)

The exhaust air of the test chamber can be fed into the
installation room and recirculated by the room ventila­tion.

NOTE – protective system failure

The instrument exhaust air system can overheat if the
maximum length of the exhaust air channel and the

maximum permissible number of two 90° bends is not

observed. This results in the protective mechanisms of

the Xenotest 440 interrupting the power supply to the

instrument.

Operating Manual Xenotest® 440

- 12 -

Inhalt/Content/Sommaire

3.4 Water supply

The Xenotest® 440 requires purified water for humidify-

ing the test chamber. Purified water circulates in a closed
pipe system which is fed from the internal 60-liter water

tank. The water tank can either be refilled manually or
connected to a water treatment system.

• Connection: G 3/8 " (inch)
The purified water must have the following quality char-

acteristics:

• Conductance: < 5 μS/cm

• pH value: 6 – 8

• Max. silicate content: 0.2 ppm

NOTE – water quality

Poor water quality not only leads to poor test results but

also affects the function and life of the components in
the instrument.

Requirements for the installation site

3.5 Transport

NOTE – Transport

The instrument may only be transported by experienced
service personnel using suitable equipment. The instru­ment may not be lifted by the front or side doors for
transport.

NOTE – lifting points (fig. 1)

The instrument may only be lifted at the lifting points
indicated in fig. 1.

Requirements for the installation site

3.6 Space requirements

Position the instrument on a sufficiently stable, nonflam­mable floor and align horizontally.

Weight of the instrument:

• Xenotest® 440 approx. 290 kg

NOTE – load at the installation site

If several instruments are to be installed in a room, en­sure the static load-bearing capacity of the floor.

An access area of at least 1 m is needed around the

machine to allow for operation, maintenance and repair
work, see fig. 2 (page 14).

• Instrument dimensions:
900 mm × 780 mm × 1800 mm (W × D × H)

CAUTION – overheating of the instrument!

The air exchange of the instrument takes

place via air inlet and outlet openings on
the top of the instrument and the side air
vents. If the air exchange is blocked, tests
will be interrupted because the safety de­vices will shut the instrument off. Also, re­peatedly turning the instrument on/off, will
shorten the life of instrument components.
Make sure that the ventilation openings are
always clear!

• The room of installation must have a minimum height
of 2.5 m

• Comply with the minimum distances at the side and

back of the instrument. The safety and maintenance
distances can be found in fig. 2 (page 14)

5.1

Xenotest® 440 program control panel

Fig. 7:

The Xenotest 440 is turned on with the main switch 3

and then operated by the keypad on the program control
panel 2. The microprocessor-aided program control
enables both opening of already pre-programmed test

sequences and the design and initialization of user­specific tests. The parameter values required for the test

are entered with the numeric block of the keyboard and
initialized by the different function keys. The inputs and
the resulting status messages are shown in the display.
The test documentation can be output in data form via

the communication interface. Detailed specifications for
the program control and programming of test sequences

are described in the instrument’s software documenta­tion manual.

5.2 XenoLogic™ Function

NOTE – XenoLogic function

XenoLogic is a new control technique based on two xe­non lamps with which high irradiances and longer useful
lives can be achieved. The lamps are operated intelli-

gently and alternately or together as required.

NOTE – expiry of useful life

On expiry of the useful life, the lamp parame-

ters that ensure proper operation of the device
are no longer guaranteed. Especially negative
effects on the results gained with these cannot

5.3 Optical filter systems

NOTE – spectral power distribution

Depending on the selected test method, the appropriate

filter system which surrounds the xenon lamps 1 in
order to create the prescribed/desired spectral energy
distribution.

5.3.1 TM16 filter system (fig. 8)

An aging-stable filter system for simulation of sunlight

behind window glass; e.g. for tests conducted in accor­dance with AATCC TM16. The filter system consists of:

• a filter lantern 2 with six optical filter 3

• the clamping springs for fixing the individual filter

5.3.2 XENOCHROME® 320 filter system/
daylight B04 filter system (fig. 9

)

Aging-stable filter systems. XENOCHROME 320 for
simulation of sunlight behind window glass; e.g. for tests
conducted in accordance with ISO 105-B02. Daylight
B04 for simulation of sunlight outdoors; e.g. for tests con­ducted in accordance with ISO 105-B04, -B10, 4892-2.

The filter systems consist of: a filter lantern 2 with elev­en optical filter as well as an additional, uncoated com­pensation filter disc 3 in the XENOCHROME 320 filter
system.
