The lateral two-leaf doors of the unit
must only be opened by XENOTEST, or
an authorized customer service engi-
neer or an electrical specialist.
Contact with live parts of a unit connec-
ted to the mains may involve electrical
shock.
Before opening the lateral two-leaf
doors disconnect unit from the mains.
Unplug the connection socket and se-
cure against replugging!
Ventilation and heating:
The climatic fan (2) is located on top of the test
chamber (1) and takes air in from the test chamber
through a filter mat (3).The air is warmed up by a
heating system (4) and led to the test chamber
through a ventilation duct.
Humidification:
Heated air is taken out of the test chamberand led
to the humidifier (6) through a flexible, heat
resistant hose (5). The humidified air is returned
to the test chamber via four humidification hoses
(7) (note fig. 10 and 11 ventilation schemes). The
water supply to the humidifier is adjusted by a
valve (8).

rel. humidity (fig. 5 Point 12) transmits the actual
values taken from the exhaust air flow of the test
chamber to the program control system. With a
target/actual comparison the requested test
parameters are adjusted permanently by adjusting
elements.
With an inserted Xenosensiv sensor (note fig. 5
Point 9) the slip ring collector (9) seated below
the test chamber transmits the measurd values to
the program control.
The fresh air supply to the test chamber is
controlled by an air flap which is adjusted by a flap
motor (10).
The ignition unit (11) in conjunction with the power
supply unit (note fig.8 Point 10) ignites the Xenon
lamp. The caroussel motor (12) drives the
caroussel in the test chamber. The turning- and
non-turning mode is switched on and off by a lifting
magnet (13). The function of the caroussel is
monitored by an inductive proximity sensor (14).
Rain:
The rain pump (15) provides the rain bar in he
test chamber with ultra-pure water. The inlet and
outlet lines of the humidifier, the water return line
from the test chamber and the supply line of the
water pump are led through the top of the water
tank (16). The water tank is emptied through the
water outlet tube (17).
The lamp exhaust air can be led to the open via a
flexible, heat resistant hose (19).
