9. Function of light measurement, and integration: Light Quantum
Control
The KBF-LQC is equipped with fluorescent tubes for UVA and the visible spectral range. These fluores-
cent tubes can be manually switched on (switch in position “I“) using switches (10) and (11) located in the
left lateral control panel. Or they can be switched on by entering a dose target value in Manual Mode
higher than a dose value already reached. In Manual Mode the fluorescent tubes are automatically
switched off when the respective dose target value is reached. The manual switches permit switching on
the fluorescent tubes independent from automatic turn-off (or to prevent automatically switching-off) and
thus to attain dose target values which are higher than the entered maximum dose. This permits inde-
pendent switching of the UV and the VIS tubes.
Intensity of illumination [LUX] and UV intensity [W/m
2
] are measured by optical sensors in the inner
chamber (actual value display) and are integrated temporally (dose display), i.e. the doses of illumination
[MLUXh] and of UV intensity [Wh/m
2
] increase every minute by the respective actual value. The position
of rocker switch (2) determines if the light values are displayed as actual values or as dose values. Actual
value display serves to help the user find a representative measuring spot after charging and to control
the correct function of the illumination equipment.
In Manual Mode, you can numerically enter target dose values for UVA and visible light. When the VIS
dose is reached the message
LUX DOSE REACHED
appears, when the UVA dose is reached the mes-
sage
UVA DOSE REACHED
is displayed. The according fluorescent tubes are switched off automatically
to avoid exceeding the selected dose. Switching off is possible only if the corresponding switches (10)
and (11) are in position “OFF”. Otherwise exposure to illumination and integration continue even after the
message until the switches are manually set to position “OFF”.
As soon as the second dose is reached as well the message
LUX AND UVA DOSE REACHED
appears
as an alarm message, and a buzzer sounds. The alarm message can be reset with the RESET key. The
alarm message can be seen in the Event List of the MB1 controller.
In Idle Mode and in Program Mode the display function of the actual values and the integrative function
can be used, but without automatically switching the fluorescent tubes and without a preselected limit of
the doses.
9.1 Illumination measurement and temporal integration
Key switch (12) in the left lateral control panel serves to start and stop the integrative function and to re-
set the integrated values of UVA and VIS.
Position of key switch “LIGHT INTEGRATOR” (12):
Position “OFF”: Integrative function off (key can be removed)
There is no integration. Previously reached integrated values, if any, remain stored but are not dis-
played.
Independent of the controller operating mode and of the position of rocker switch (2), the actual values
of UVA and VIS are displayed under X.
In Idle Mode and in Program Mode, 0.0 is displayed under W; in Manual Mode the respective dose
target values are displayed under W.
On the lower left part of the controller, the notifying message “
LIGHT INTEGR. OFF
” is displayed al-
ternating with the units “LIGHT kLUX W/m
2
”.
The illumination equipment can be turned on and off by hand with switches (10) and (11).
Position “ON”: Integrative function on (key can be removed)
Integration takes place as soon as the key switch (12) is in position “ON” and at least one target dose
value other than 0.0 has been entered. With target dose value 0.0, the fluorescent tubes are not
switched on automatically. The illumination can be switched on and off using switches (10) and (11).
