and filtered through an optical filter "coated quartz fil-
ter segment" ".
NOTE:
There are optional optical filters (see Chapter 5 "Acces-
sories") available for various spectral distributions (see
chapter. 4.3, "Spectraldistributionwithadditionalfilters").
• The UV component of the radiation that is directed
upwards is reflected on the specimens &by the mir-
rors!placed above the Xenon lamp #.
• Thecomponentsofthenon-dangerousIRradiation(heat

remaining heat is removed out of the unit via the air
circuitof the Xenon lamp.

4.2 Ventilation circuits
• The coolant air of the Xenon lamp and the test cham-
ber !is aspirated on the rear side of the unit (see
chapter 3.3, "Rear side of unit") through an air filter,
flowsthrough thetest chamber andthe assemblycom-
partment of the irradiance unit and exits through the
exhaust openings "(at the left and the rear side of
the unit (see chapter 3.3, "Rear side of unit").
NOTE:
Duringcontinuous operation, the hot air emittedbythe air
cooling system results in a continuous change in the cli-
mateinside the chamber.

4.4 Sensor system in SUNTEST CPS+
SUNTEST CPS+ has integrated sensors:
• Sensor for measuring the global irradiance (E) in the
rangeof 300- 800 nmand for regulationin the rangeof
250 -765 W/m²,
• Sensor for measuring and regulating the black stan-
dardtemperature(BST)up to about 100 °C,
• Sensor for measuring the test chamber temperature
(TCT).
Irradiance (E):
• Duringtesting, irradianceis measured bya photodiode
!and regulated electronically to achieve a constant
value.
Black Standard Temperature (BST)
• During testing the black standard sensor (BST sen-
sor)"continuously measures the temperature.
• Theblack standard temperature(BST) is regulated via
the speed of the test chamber ventilator.
Test chamber temperature (TCT):
• Thetest chambertemperature(TCT) ismeasuredby a
temperature sensor in the exhaust air flow of the test
chamber.
• The test chamber temperature cannot be controlled
andis indicated in the display unit of the program con-
troller.
Measurement data:
• The measurement data can be transferred, with the
testing program running, via the RS 232-port at the
rear side of the unit to a PC or a printer with a serial
interface.
