The Artiste Van Gogh has got several options of fan modes and low noise operation available. So you’re able to adjust the fan behaviour for certain applications and environments. If you have an event or a noise critical environment where you need an absolute silent fixture or fan noise reduced, such as Theater, Opera or Orchestra Halls, it offers various fan operation modes which remove any distraction for the audience and performers. Conversely, you may be in a very high temperature environment where the noise maybe isn’t an issue, but the fans may need to run at 'High' for a certain time.
Fan Modes can be changed remotely via the DMX control channel, allowing the fixture to offer high output or quiet operation within seconds. Alternatively, they can be set in the fixture menu (Personality > Fans Control > select one of the 5 options)
All Fan Modes smoothly transition over a brief time period, preventing unwanted attraction to the fixture.
Your Van Gogh fixtures should have the latest software version installed to make sure all options are available to you, please download here - viewtopic.php?f=3&t=237&p=281&hilit=art ... eb902#p281
Here are the 5 options and a description of each –
Auto (Default) –Fans only run at the speeds needed to keep the LED engine within a safe temperature range and ensures optimal performance of the fixture. They will turn off if possible, for example when the fixture is dimmed to a low intensity. Fans sense the ambient and fixture temperature and will at all times try to keep noise levels at a minimum.
The fixture output will only reduce when the LED engine cannot be cooled down to its safe operating range due to high ambient temperature.
NOTE: Recommended for daily operation.
Low – Fan speeds are reduced throughout for a lower noise profile. The fixture output is also reduced to approximately 80%. This mode should be sufficient for most uses where lower noise is required.
High – Fan speeds are increased throughout for the most efficient cooling of the fixture. This mode will increase wear on the fans and should only be utilized in exceptional circumstances. Fans will always run, even if the fixture is dimmed down. Fixture output is kept at 100% unless the LED engine temperature reaches an unsafe temperature at which point the fixture will reduce power carefully to ensure continued safe operation. This mode is only required in very high ambient temperatures when automatic fan speed adjustments are not desired.
Low Noise Modes
For very critical noise environments, the fixture offers two additional Low Noise Modes for silent operation. The fixture output will be reduced, however due to the extremely high luminous flux the fixture still offers outstanding performance. In Low Noise Modes all parameters of the fixture operate quieter with reduced fan speeds.
Studio – Almost all fixture fans are turned off and only run when absolutely necessary. The fixture LED power output is reduced to 50%.
Mute – All but one fixture fan is turned off for whisper quiet operation. The fixture LED power output is reduced to 25%.
