2Installation of equipment
2.3 Location requirements
Climatic conditions required for the place of installa-
tion:
• During continuous operation, the hot air emitted by
the air-cooling system results in a constantly chan-
ging climate in the room. Therefore, the SUNTEST
equipmentshould onlybe installedin air-conditioned,
sufficiently ventilated places of installation.
• The places of installation must be kept free of dust.
• The room temperature must be maintained between
18°C and 25°C.
• The max. relative humidity should be 70%.
The requirement for coolant air is as follows:
• Lamp cooling 250 m³/h,
• Air conditioner for the test chamber 340 m³/h.
Installation:
• Dimensions of equipment (width x depth x height):
930 mm x 500 mm x 485 mm,
• Weight of equipment approx. 80 kg,
• The equipment must be set up on a sufficiently stable
laboratory bench with a non-flammable support un-
derneath and the laboratory bench should be aligned
so that it is horizontal.
• Please lift the unit for any displacement to avoid that
the rubber feet fall off the fixing screws.
Caution - Overheating of the equipment:
Blocking of the air inlet and air outlets can result in
overheating and damage to the equipment!
When installing the equipment, the following mini-
mum distances to the neighboring walls or objects
must be maintained:
to the front 700 mm
to the back 500 mm
to both sides 300 mm
on top 400 mm.

The radiation $is generated by the Xenon-Lamp #.
The radiation $is filtered through an optical filter
"coated quartz dish" %.
Note!
There are optional filters (see Chapter 5, „Accessories’)
available for various spectral distributions (see chapter.
4.1.3, „Spectral distribution with additional filters“).
• The UV-component of the radiation, that is directed
upwards, is reflected on the specimens !by the
mirrors &that are placed above the Xenon lamp #.
• The components of the non-dangerous IR-radiation
(heat radiation) are absorbed by an absorber, and re-
moved out of the equipment via the air circuit of the
Xenon lamp.

4.2 Ventilation circuits
• The coolant air of the test chamber !is sucked in-
ward on the rear side of the equipment (see chapter
3.3, „Rear side of equipment“) through an air filter,
flows through the test chamber and exits at the bot-
tom of the equipment ".
• The coolant air of the Xenon lamp #is drawn in on
the rear side of the equipment (see chapter 3.3,
“Rear side of equipment”) through an air filter, flows

on the exhaust opening on the rear side $.
NOTE!
During continuous operation, the hot air emitted by the
air cooling system results in a continuous change in the
labboratory climate.

4.4 Sensor system in SUNTEST XLS+
SUNTEST XLS+ has integrated sensors:
• Sensor for measuring and controlling the irradiance
(E) in the range 300 - 800nm,
• Sensor for measuring and regulating the black stan-
dard temperature (BST) in the range ambient tempe-
rature up to about 90°C,
• Sensor for measuring the test chamber temperature
(CHT).
Irradiance (E):
• During the testing, the irradiance is measured by a
photo-diode !and controlled electronically to achie-
ve a constant value.
Black Standard Temperature (BST)
• Duringthe testing, temperature measurementsareta-
ken continuously by the black standard-sensor (BST)
".
• The black standard temperature (BST) is controlled
via the speed of the test chamber ventilator.
Test chamber temperature (CHT):
• The test chamber temperature (CHT) is measured by
a temperature sensor in the exhaust air flow of the
test chamber.
• The test chamber temperature cannot be controlled.
The test chamber temperature is indicated in the dis-
play unit of the program controller.
Measurement data:
• The measured data can be transferred, with the te-
sting program running, via the RS 232-port #toa PC
or a printer with a serial interface.

4.5 Safety devices
There are safety and protection devices that increa-
se the operational and functional safety of the equip-
ment:
• To switch off the equipment in an emergency, set the
ON (I) / OFF (0) switch !to position “OFF (0)”.
• A door switch switches off the equipment when the
test chamber door "is opened.
• Asafety switch interrupts the power supply when the
covering hood #is pushed back.
• The gas-pressure spring $on the door of the test
chamber stabilizes the door in its open position.
• A temperature safety device switches off the equip-
ment if there is a danger of the Xenon lamp getting
overheated because of insufficient cooling.
Figure 9
4.6 Safety markings
Please check whether the safety markings mentio-
ned below have been put on the equipment.
If any of the safety markings should be absent, plea-
se inform your supplier.
• The safety notice “Pull out power plug” !on the ab-
sorberprovides a warning about touching live partsof
the equipment.
• The safety notice “Warning of danger" "on the ab-
sorber warns about touching the radiation system
when it is hot and about sharp edges on the optical
filter and reflecting mirror.
• The safety notice “Warning of danger” #on the door
of the test chamber warns of a possible danger of
fingers getting caught in the door of the test chamber
if the door is closed abruptly, and of touching hot spe-
cimens.
So also, there is a warning about the dangers of the
UV-radiation being emitted if the sample table is not
fitted.
• The notice “Do not open!” $on the gas pressure
spring warns about opening the gas pressure spring,
which is under high tension.
