7.7 Fan
The BEAM 250 XT is cooled by one axial fan. The speed of the fan (and of course the noise) can be continuously
reduced if very quiet performance is required.
By the Control Board using the „FAnS“ function you can choose 4 types of the fan speed operating modes:
1. „HIGH“ - high speed of the fan
The cooling fan works on max. speed (max. cooling).
2. „reG“ - continuous controlling of the fan speed
The fan automatically raises its speed in order to control inside temperature of the lighting, if the temperature
inside increases about certain level (the low fan speed reduces the cooling of the lighting). This cycle can
repeats several times until the temperature inside is on suitable level.
3. „Lo.OF“ - low speed / Switch off the lamp
The fan keeps the adjusted low speed until the temperature exceeds max. inside temp. then the BEAM 250 XT
automatically switches off the lamp.
4. „Lo.HI“- low/high speed of the fan operating
The fan keeps the adjusted low speed until the temperature exceeds max. inside temp. of the fixture, then the
BEAM 250 XT automatically switches from low to high the fan speed.
8. Control Board
The control board situated on the rear panel of the BEAM 250 XT offers several features. You can simply set the
lighting address, read the number of lamp or unit hours, switch on and off the lamp, run test show, make a reset
and also use special functions for manual control and service purposes.
