Gemini Fan Settings

They spin and spin and spin

The fan behavior in Gemini fixtures can be set either manually (in the FIXTURE CONFIG -> FAN CONFIG menu) or through DMX control via DMX Profiles with the FAN MODE parameter. (see dmx chart for details)


Fan Control Options

  • Fan Auto: The fan will come on when fixture is at full power

  • Fan Delayed: The fan will come on only at high internal temperatures

  • Fan Max: Fan will always run at maximum speed

  • Fan Off: For silent operation but the maximum intensity is limited to 50% as maximum

  • Fan DMX Controlled: When using a DMX Profile with the FAN CONTROL parameter, you can control the Fan options from your lighting console or other dmx control device. (Auto, Off, Delayed, Max).
