Operation
Ambient temperatures
Devices can be operated within the following temperature ranges only:
• Alien LED driver units can be operated at ambient temperatures from 5° C (41° F) to 40° C
(104° F).
• Alien LED Downlight transformers can be operated at ambient temperatures from 0° C (32° F)
to 40° C (104° F).
• Alien LED Downlight luminaires can be operated at ambient temperatures from -25° C (-13° F)
to 45° C (113° F).
Status LEDs on the driver unit
Colored LEDs on the driver unit indicate current system status:
• Green = mains power on
• Yellow = valid DMX signal is present at DMX input
• Red = driver unit is in program mode
DMX-controlled operation
When the Alien LED Downlight system is set up for DMX-controlled operation, faders on the
DMX controller are used to control color and intensity. The control method depends on which
color control mode the Alien LED Downlight system is set to (see “Setting the color control mode
to RGBW or HSI” on page 21):
In RGBW mode, four channels on the controller are used to control the intensity of red, green,
blue and white from 0% to 100%.
In HSI mode, three channels on the controller are used to control hue, saturation and intensity.
• Hue is controlled in the following order: Red
→
Orange
→
Amber
→
Yellow
→
Green
→
Cyan
→
Blue
→
Indigo
→
Violet
→
Magenta
→
Red.
• Saturation and Intensity can be varied from 0% to 100%.
When the Alien LED Driver Unit is receiving a valid DMX signal, the yellow DMX OK LED next to
the DIP switch on the Driver Unit lights.
Stand-alone operation
When the Alien LED Downlight system is set up for stand-alone operation, downlights begin
displaying their stand-alone scene as soon as power is applied to the driver.
