Fan modes
The four different cooling fan modes give you a range of options to choose from
depending on how much you want to give priority to high-intensity light output or to
low fan noise:
• Regulated gives priority to light output. If the luminaire is blacked out, fans run at
minimum speed. When light output intensity is increased, temperature regulation
increases fan speed to the level necessary to keep the luminaire at optimum
temperature.
• If light output is set to maximum intensity but the fans can keep the luminaire at
optimum temperature, there will be no regulation of light intensity. If the luminaire
begins to exceed optimum temperature, light intensity will be reduced until
optimum temperature can be maintained.
• High mode is optimized for maximum light output and suits operation in high ambient
temperatures. Fans are set to constant operation at high speed and light output
intensity is regulated in order to keep luminaire temperature at optimum level.
• Besides maximizing light output in high ambient temperatures, you can use this
mode to cool down a luminaire quickly or to remove dust from cooling fans.
• Medium mode is suitable for low-noise operation in normal ambient temperatures.
Fans are set to constant operation at medium speed and light output intensity is
regulated in order to keep luminaire temperature at optimum level.
• Low mode is optimized for minimum noise. Fans are set to constant operation at low
speed and light output intensity is regulated in order to keep luminaire temperature at
optimum level.
• This mode gives an extremely low fan noise level, but if you use it in high ambient
temperatures there may be a noticeable reduction in light output intensity.
In all fan modes, if luminaire temperature reaches a dangerous level, LEDs will be shut
down for a period until the fans have brought the temperature down to a safe level.
You can set the cooling fan mode using the control panel or the Control/Settings DMX
channel.
Movement performance
Three settings are available for the movement of mechanical effects (pan, tilt, zoom
etc.):
• In Normal mode, movement is set to achieve a balance between speed, noise and
smoothness that will be best in average situations. This is the default setting.
• In Fast mode, all movement is set to high speed. This mode gives impressively fast
effects, but noise levels will be higher than in Normal mode.
• In Smooth mode, movement is optimized to obtain the smoothest action and lowest
noise. This mode gives super low-noise operation and smooth performance, but effect
movement is slower than in Normal mode.
You can select movement performance settings using the control panel or the
Control/Settings DMX channel.
