Fan
The MH-660 is cooled by three axial fans - one each in the projector head and one in the base. 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 low fan speed operating:
1. "HIGH" - high speed of the fans
The cooling fans work 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 repeat 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 MH-660
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 MH-660 automatically switches from low to high the fan speed.
The Control Board situated on the top side of the MH-660 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 demonstration
sequences, make a reset and also use special functions for manual control and service purposes.
