18.2 Replacement of the fluorescent tubes
The average life expectancy of the fluorescent tubes is about 10,000 hours. We recommend replacing
the tubes every year in order to ensure full light intensity.
To replace the fluorescent tubes, unscrew and remove the clamping strips resting against the glass plate
(Allen screwdriver). Then lift the plate from the cassette. Rotate the tubes by 90° and pull them out of
their holders. When setting in the new tubes, observe the tube orientation (inscription, Figure 26). Fix the
glass plate screwing the clamping strips.
Figure 39: Dismounting a light cassette
Always replace all the fluorescent tubes of a light cassette together. Otherwise, homogeneity
of light intensity cannot be guaranteed.
18.3 Calibrating the light sensors and adjusting the controller display
The light sensors are delivered with a calibration certificate on which at least 2 measuring values with the
corresponding measuring current values are indicated. So it is possible to adjust the input channels to the
sensor current values. Instead of the sensor a calibrating device is plugged in the sensor socket inside
the chamber. This source of current is voltage stabilized and independent from the power supply voltage.
The supply point for the sensors inside the chamber is automatically left out.
