- sample holder mountings (5).

Function:
The samples rotate around the lamp and filter lan­tern. In turning mode operation the samples are
turned by 180° per caroussell revolution.

Ventilation:
Test chamber and Xenon lamp are supplied by two
separate air flows. A uniform air ventilation is achie­ved by an appropriate air flow (fig. 10 ventilation
scheme).

Temperature, humidification and rain:
Air is taken from the test chamber by an air ex-
haust hose (6), warmed up by a heating system
and humidified in the humidifier, and then sent back
to the test chamber by an air supply hose (7).
The maximum chamber humidity can be adjusted
up to 95% r. h. depending on the preset tempera­ture.

The rain bar (8) mounted in the test chamber is
used to spray ultra-pure water in cyclical intervals
and without any pressure on to the specimens.

Sensors:
At sample level a XENOSENSIV sensor (9) for
measuring the irradiance in the range between
300-400nm and the black standard temperature in
the surface temperature range up to 130°C can
be fitted to the test chamber by means of an ad-
apter (10) (fig. 31). The sensor is connected to
the program control via a connection socket (11).
If no sensor is used the end plug must be fitted to
the connection socket (fig. 36).
A sensor to measure the test chamber tempe-
rature and rel. humidity (12) is mounted in the
upper rear of the test chamber. The sensors com­bined with the program control guarantee control
of constant setting values.

Contrast to ALPHA:

Are locared in the test chamber:

- arc-shaped Xenon lamp (1)

Ventilation:
A uniform air ventilation of the sample area is achie­ved by an air conduction plate (2) (fig. 11 venti­lation scheme).

Data output:
Data of stored programs as well as current measu­ring values can be printed-out by a thermoprinter
(2). The interface (3) on the right-hand side of the
main switch provides for the data output and ex­ternal computer control.

Electrical components:
The mains transformer of the humidifier (5), the

control transformer (6), a mains voltage inter-
ference filter (7) and the fuse base of the con­trol voltage (8) are located below the test cham-
ber (4).

The power supply unit (10) of the lamp is moun-
ted below a protective wire mesh (9).
The mains transformer (11) and the lamp choke
(12) (not HIGH ENERGY unit) are located below
the power supply unit. The heating relay (14) is
seated next to the main contactor (13) and the
control of the test chamber fan (15). There is a
25 amps lamp fuse (16) protection and a 10 amps

heating fuse (17) protection. The operating hour
counter (18) records the operating time of the

equipment.

Ventilation:
The air intake for the lamp cooling (19) passes
through a filter pad in the equipment door.

The main switch (1) (fig.7) is located on the upper
left of the unit. Use this switch to disconnect the
unit from the mains in case of trouble.

The lateral two-leaf doors of the unit
must only be opened by XENOTEST, or
an authorized customer service engineer
or an electrical specialist.
Contact with live parts of a unit connec­ted to the mains may involve electrical
shock.
Before opening the lateral two-leaf doors
disconnect unit from the mains. Unplug
the connection socket and secure
against replugging!
