Inhalt/Content/Sommaire

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

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

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)

5.2 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 be ruled out. Use of the lamps beyond the useful life specified by Atlas is therefore at your own risk.

5.6 Ventilation system

The Xenotest® 440 is an air-cooled instrument. The cooling system uses two different air sources.

• Air flow system for the lamp cooling

• Air flow system for the test chamber cooling

5.6.1 Lamp cooling

Fig. 14:

The cooling air for lamp cooling is brought in by a fan and enters through the air vents 3 on the right hand side of the instrument. The air current flows along the right hand module shaft and cools the electronic components first. The air is then fed through the outer cylinder 2 and cools the xenon lamps. The heated cooling air emerges from the air vent on the top of device 1 and must be extracted by a separate exhaust system

(see 3.3).

CAUTION – overheating!

If the exhaust air current impairs the cool-

ing of the lamp, the instrument may overheat and cause damage to the samples. The exhaust at the top of the instrument must always be kept clear!

5.6.2 Test chamber cooling

Fig. 15:

The cooling air 1 for cooling the test chamber is brought in by the fan 9 at the air inlet opening 7 though the air filter 8. Depending on the temperature preset in the test chamber, the volume of cooling air is controlled by a motordriven vent 6. The air is fed past the heating system B where it is heated to the necessary temperature, then mixed with humid air in the humidity system C according to the preselected values and fed in through the air shaft on the rear wall of the test chamber 4. The air is distributed evenly over the sample rack 3 and the temperature and humidity are measured continuously by the integrated sensor system 2. The used air A is passed through the air outlet 5 in the front left section of the test chamber and, together with the heated cooling air of the lamp cooling, is either exhausted by a technical ventilation system or discharged directly into the outside air.

5.7 Humidity function

The humidity function of the Xenotest 440 enables samples to be tested under controlled humidity conditions.

• The humidification of the test chamber is generated

by an aerosol-free ultrasonic humidifier.

Fig. 16:

The humidity system is fed from a water tank 1 inside the instrument. The fill level of the water tank is monitored by a float valve 4. A magnetic switch 3 reports the fill level to the program control. There is an immersion pump 2 in the water tank which supplies the humidifier 5 with water for air humidification. Water flows back into the tank via return tubes 6.

5.8 Sample spraying

The sample spraying of the Xenotest® 440 enables spraying of the samples with the processed water during a wet cycle.

Fig. 17:

The humidifier as well as the sample spraying are fed from a water tank 1 inside the instrument. The filling level of the water tank is monitored by a floating switch

4. A magnetic switch 3 reports a low water fill level to the program control panel. The following pumps are installed:

• The immersion pump 2 which supplies the humidi- fier 5 with water for air humidification.

• The spray rod 7 supplies water from the water tank into the spray lance 8 for spraying the samples.

Draining water is fed into the water tank or into a gravity

drain through the return pipe 6.

NOTE – Fresh water operation

The purity of the water is an important criterion for the test. Therefore, it is recommended that the return line 6 is connected to the laboratory drain (gravity drain) if the samples give off particles in the test with spraying.

The water tank inside the instrument is then constantly supplied with fresh, processed water by a water treatment system or from an external tank.

Weathering tests of materials which release chlorine or

reactive chlorine compounds during weathering tests or extract with spray water should only be conducted in fresh water operation. In this case, the return pipe 6 must be connected to a laboratory drain!

6.6 XENOSENSIV® RC

6.6.1 General

The XENOSENIV RC sends the measured data to the

instrument by a wireless connection. The instrument

must be equipped with an appropriate receiver.

The sensor is available in the following versions:

XENOSENSIV RC-34 BST XENOSENSIV RC-420 BPT

6.6.2 Sensor allocation

Every XENOSENSIV RC must be allocated to an instrument. This is especially important when operating several instruments. After the allocation, the instrument only receives data from the sensor allocated to it. This sensor may only be used in this instrument. The allocation remains valid until another sensor is allocated to the instrument.

The ID and serial number of the sensor allocated to the instrument can be requested by the instrument control

panel. If a sensor is allocated to several instruments, only one of these instruments may be switched on otherwise transmission errors will occur.

Allocating XENOSENSIV RC to an instrument:

NOTE – sensor allocation

This process may not be performed on several instruments simultaneously.

• Open the XENOSENSIV menu in the instrument control panel (see software documentation manual) and

select the sensor function. Once this function is selected, for a period of approx. 10 seconds, the instru-

ment will be ready to receive a connection to a new sensor.

• Hold the included magnet 1 (fig. 30) against the top of the sensor for approx. 2 seconds. The sensor then sends its contact data (frequency and channel number) to the instrument.

• The process can be repeated if necessary.

• After successful allocation, the ID and serial number

of the sensor allocated to the instrument is displayed for verification.

• Any existing calibration factors which were determined for the old (previous) sensor must be deleted.

NOTE – screw

The screw 2 may not be removed.

NOTE – adhesive label

The field on the back of the sensor may not covered with (metal) adhesive labels.

Setting the test chamber humidity

The desired humidity in the test chamber is entered as a parameter on the instrument control panel. The maximum humidity which can actually be achieved in the test chamber depends on the ambient conditions. In addition, the amount of humidity which must be introduced into the test chamber by the humidifier has an influence on the maximum temperature which can be reached

in the test chamber. Under dry ambient conditions, the

maximum settable sample chamber temperature in the device may not be reachable.

Fig. 40:

The diagram shows the maximum achievable sample chamber humidity at a given sample chamber tempera-

ture under dry laboratory conditions, i.e. 20 °C and approx. 30% relative humidity, with closed air vent. With

the air vent open, the achievable humidities are lower and highly dependent upon the ambient laboratory conditions.

7.4 Temperature fields

Fig. 41:

The diagram shows the ΔT temperature fields for XENOCHROME® 320 and daylight B04 depending on the irradiance. The black standard temperature (BST)

is regulated by the fan speed and dependent upon the irradiance, test chamber temperature and the selected filter system. The setting range for the fan speed is be-

tween 500 and 2,500 rpm. Minimum ΔT values are possible at maximum fan speed and maximum ΔT values at

minimum fan speed. Tolerances are possible within the

temperature fields shown in Fig. 41.
