Figure 24: Arrangement of the fluorescent tubes in the light cassette KBF LQC 240
The fluorescent tubes are turned on by two switches (10) and (11) on the left lateral control panel
(switches in position “I“).

The fluorescent tubes can be turned on manually by switches (10) and (11) or by entering a dose set-
point value in Manual Mode higher than a dose value already reached. In Manual Mode the fluorescent
tubes automatically turn off when the respective dose target value is reached. The manual switches per-
mit turning on the fluorescent tubes independently from that value or to prevent automatic turning off. This
enables attaining dose values, which lie above the entered maximum dose.
You will obtain optimum homogeneity by alternately placing the fluorescent tubes of the same type, i.e.,
opposite arrangement of the inscription:

When replacing the fluorescent tubes, observe tube orientation (inscription).
The description how to replace the fluorescent tubes is given in chap.18.2.
Operation with light cassettes and illumination on: Maximum temperature 60 °C / 140°F.
Operation with light cassettes and illumination off: Do also NOT operate the unit at tempera-
tures >60 °C / 140°F. Otherwise the lifetime of the fluorescent tubes will be considerably re-
duced.
When operating the chamber at temperatures > 60 °C / 140°F, remove the light cassettes.
Entering the set point values when operating without illumination:
•
Adapt the setting of the temperature set-point according to the table in chap. 8.2.
• Adapt the setting of the humidity set-point according to the table in chap. 8.2.
