Fan Control - Elation KL FRESNEL 6 CW PO User Manual

F A N C O N T R O L
The KL Fresnel 6 CW PO is a high-performance fixture suited for multiple applications. For
noise critical environments such as Theater, Opera, or Orchestral Halls, it offers various fan
operation modes which remove unwanted noise distractions for the audience and performers.
Fan Modes can be changed remotely via the DMX control channel, allowing the fixture to offer
high output or whisper-silent operation at a moment's notice. All Fan Modes smoothly transi-
tion over a brief period, preventing unwanted attraction to the fixture.
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 pos-
sible; 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 be reduced when the LED engine cannot be cooled to its safe operating range
due to a high ambient temperature.
NOTE: This mode is recommended for daily operation.
High – Fan speeds are increased throughout the fixture for the most efficient cooling. 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. Fixture output is kept at 100% unless the
LED engine temperature reaches an unsafe temperature, at which point the fixture will re-
duce 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 - For very critical noise environments, the fixture offers two additional Low Noise Modes
for silent operation. The fixture output will be reduced, yet due to the extremely high lumi-
nous flux, the fixture still offers outstanding performance. All parameters of the fixture oper-
ate more quietly with reduced fan speeds. Almost all fixture fans are turned off, and only run
when absolutely necessary. The fixture LED power output is reduced to 50%.
