• Room temperature: between 18 °C and 25 °C

• Relative humidity: 50 % max

3.2 Room ventilation

The room where the instrument is installed must be connected to an air recirculation system with a capacity that ensures an incoming volume of air of at least 400 m³/h. The incoming air must be cleaned using a filter of filter class EU 4 The laboratory room must be kept free from dust.

3.3 Instrument exhaust air system

The irradiator cooling of the XENOTEST BETA+ must be connected to an exhaust air system. The irradiator cooling exhaust air can be routed directly into the open if the exhaust air system complies with the following:

• The exhaust air duct must be made of flexible, heat-resistant material since the exhaust air temperature can rise up to 120 °C.

• The length of the exhaust air duct must not exceed 3 m.

• The exhaust air duct must have a minimum diameter of 100 mm. The connecting sleeve at the XENOTEST BETA+ has a diameter of 100 mm.

• The exhaust duct must not have more than two 90° elbows.

• If a length of more than 3 m or more than two 90° elbows are required, an on-site exhaust air blower must be installed.

The exhaust air from the test chamber can be routed into the room where the instrument is located and recirculated by the room ventilation system.

NOTE - Function impairment If the maximal length of the exhaust air duct

and the permitted number of 90° elbows (max

2) are exceeded, the instrument exhaust air system may overheat. In this case, the safety devices of the XENOTEST BETA+ will interrupt the power supply of the instrument permanently.

Operating instructions XENOTEST BETA+

3. Location requirements

3.4 Water supply system

For the humidification of the test chamber and for spraying the samples with water, the XENOTEST BETA+ requires treated water. This treated water circulates within a closed system; the system is fed from the instrumentintegral reservoir or the used water is removed immediately from the XENOTEST BETA+. The water reservoir can either be filled manually or be connected to a water preparation system.

• Connection G 3/8 "

The treated water must have the following quality characteristics.

• Conductance < 5 µS/cm

5. Functional description

5.4 Ventilation system

Fig. 11: The XENOTEST BETA+ is air-cooled. The cooling system is supplied with two

different airflows: irradiator cooling D and test chamber cooling 6.

Irradiator cooling:

A blower C aspirates the air D for the irradiator cooling at the air vents 3 at the right side of the instrument. The air flows along the assembly duct and cool the electronic components. Then, the air is routed through the external cylinder 2 of the irradiator unit and cools the Xenon irradiators. The heated air is carried off through the vent at the top of the device 1 and is aspirated by a technical ventilation in or removed directly out of the laboratory.

Test chamber cooling in fresh air mode:

The air 6 for the test chamber cooling is aspirated by the blower 9 through the air filter 5 at the air inlet opening.

Depending on the present temperature in the test chamberF, the fresh air feed rating is controlled using the motor-driven doors 3 and 7. The airflow is routed past the heating system 8 and heated to the required temperature. The humidification system A then mixes the air with humidified air and feeds the mixture into the test chamber F. The humidification system removes air from the test chamber through the inlet air pipe B. The airflow E is distributed evenly around the sample turntable while temperature and humidity are constantly measured by the integral sensor system 2. The used air is carried off through the exhaust air opening 4 and is aspirated by a technical ventilation in or removed directly out of the laboratory.

Test chamber cooling in recirculating air mode:

In the recirculating air mode, the two air doors 3 and 7 are closed so that the airflow is routed into the closed air recirculation system.

Fig. 11

Operating instructions XENOTEST BETA+

5. Functional description

5.5 Spray and humidification system

The spray and humidification system of the XENOTEST BETA+ allows samples to be tested under clearly defined climatic conditions in the test chamber.

• The humidification system controls the relative humidity of the air within the test chamber. The settable range is between 10 % and 95 %. The test chamber is humidified by 8 ultrasonic atomizers.

• The spraying system sprays treated water through a sprayrod in cycles onto the samples without pressure.

Fig. 12: The spray and humidification system is fed through an instrument-integral water reservoir 4. A float switch 6 monitors the filling level of the water reservoir and a magnetic switch 5 reports an excessively low filling level to the program control. Two pumps are installed in the water reservoir:

• One pump 7 supplies the humidifier 2 with water for air humidification.

• The other pump 9 supplies the sample backside cooling E with cooling water trough a separate supply pipe.

Other pumps:

• The spray pump B pumps the water from the reservoir into the spray rods D that spray water onto the samples.

Water flowing off is fed back through the return pipe A into the reservoir or into a gravity drain. The water reservoir can be drained using the drain plug 8 .

NOTE - Fresh water supply If the samples release particles during a test

with spraying, and if the cleanliness of the water is an important criterion for the test, the spray and humidification system can be connected through the sleeve 3 to an external water circulation system. The water return is then connected to the drains (gravity drain). The instrument-integral water reservoir is continuously supplied with fresh, treated water from a water treatment system or from an external reservoir.

Operating instructions XENOTEST BETA+

5. Functional description

5.6 Measuring and control of sensor system

A combined test chamber temperature/humidity sensor is installed in the test chamber of the XENOTEST BETA+. This sensor is used to default and constantly control the chamber temperature and humidity. The XENOSENSIV sensor can be installed as an option. This sensor moves synchroneously with the samples and captures the measured values of the black standard temperature at sample level (within a temperature range of 0 °C to 130 °C) as well as the measured values of the irradiation intensity within a wavelength range of 300 nm to 400 nm. The program control uses the measured values to control the preset parameter values.

Integral sensor system, Fig. 13:

The sensor system 2 installed in the test chamber measures:

• the chamber air temperature and

• the relative humidity.

This measuring system supports the following functions:

• Display of the measured chamber air temperature on the touch screen of the control.

• Constant control of the chamber air temperature according to default values up to 80 °C max.

• Control in accordance with relative electric irradiator rating (0 or 53 to 120 %). 100 % irradiator rating corresponds with a nominal rating of 2200 VA. The control range 100 to 120 % indicates irradiator aging.

• Display of the measured relative humidity in the test chamber on the touch screen of the control.

• Constant control of the relative humidity in the test chamber according to default values up to 95 % r. h. max.

7.7 Temperature fields

The black standard temperature (BST) and the chamber air temperatur (CHT) or the difference between the two: ∆T = BST-CHT is of utmost importance for the material testing. The two diagrams show the temperature fields ∆T for the various filter systems in dependence of the irradiation intensity. The black standard temperature is controlled through the blower fan speed in dependence of illumination intensity, chamber air temperature, and selected filter system. The settable blower fan speed range is 800 to 2500 rpm.

At maximum blower speed, minimum ∆T values can be achieved; at minimum blower fan speed, maximum ∆T values can be achieved. With the idealized representation of the temperature fields, deviations are possible.
