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 24). Fix the
glass plate screwing the clamping strips.
Figure 38: 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 supplied with a calibration certificate giving at least 2 measuring values with the
related measuring current values.
For recalibrating the light sensors, send the sensors to BINDER factory service.
If an independent reference measuring device is used to directly compare the light intensities,
it must bear the same spatial sensitivity characteristics (spherical) as the sensors of the
BINDER system (chap. 16.4).
