Dimming curves
The electronic dimming effect provides smooth 16-bit dimming of the Main module
and Sub modules. The following three dimming curves are available:
● The Linear setting gives a dimming curve that the eye perceives as linear.
● The S-Curve setting gives finer control at lower light levels and at higher light levels,
with coarser control at medium light levels.
● The Soft setting gives finer control at lower light levels, where the eye is most
sensitive to changes in light intensity, and coarser control at higher light levels.
Note: Depending on the selected Subfixture Mode, the dimmer and shutter channels
of the Sub modules can operate independently of or subordinately to the dimmer and
shutter channels of the Main module.
Fan modes
Five cooling fan modes let you give priority to lowest fan noise or most powerful
cooling:
● Regulated mode gives priority to light output and only operates fans as necessary. If
the fixture is blacked out, fans switch off after some seconds. Only the fans that are
necessary operate, and they run at minimum speed. When light output intensity is
increased, temperature regulation increases fan speed to the level necessary to
keep the fixture at optimum temperature.
If light output is set to maximum intensity but the fans can keep the fixture at
optimum temperature, there is no regulation of light intensity. If the fixture begins to
exceed optimum temperature and the fans are running at maximum speed, light
intensity is limited until optimum temperature can be maintained.
● High mode sets the fixture to give maximum light output and suits operation in high
ambient temperatures. Fans are set to constant operation at high speed. Light
output intensity is limited smoothly if it becomes necessary in order to keep fixture
temperature at optimum level.
You can also use High mode to cool down a fixture quickly after a period of
operation or to help remove dust from cooling fans.
● Medium mode sets fans to constant operation at medium speed. Light output
intensity is reduced to a level where it will normally remain constant at ambient
temperatures of up to 45° C (113° F). Intensity is smoothly limited further if it
becomes necessary in order to keep fixture temperature at optimum level.
