Fan Speed and Control
All Vari-lite and Strand lighting luminaires will be governed by the same Fan
speed v Noise levels v Maximum power output rules as details below. These
noises related to these levels will confi rm to Noise Criteria levels details of
which are contained within the document.
There are 3 control parameters can be selected separately or in conjunction
when permitted to manage Fan speed v Noise levels v Maximum power output.
NOTE:
Not all fi xture have all modes or functions refer to DMX map and User
interface menu tree to see if you product has one of more of these functions.
Item 1 - Fan ‘v’ Output Preset Modes
These modes are selectable at either / or the fi xtures DMX control channel or
via the fi xture user interface screen. The section of the modes works in con-
junction with Items 3 and will also active or deactivate the Item 2.
Boost mode – LED output boosted to >120% of standard output fan speeds
increased manage heat level of LED (may be limited to only run for XXhrs).
Fixture will not exceed NC45 – NC55 sound levels in this mode
Standard mode - Full LED Fan Spin at top speed (loudest setting).
Fixture will not exceed NC40 sound levels in this mode
Studio Mode - Fan speed reduced to appropriate amount to reduce dB levels
>10% of full speed + LED @ max output approximately 80% of Standard output
at appropriate level to ensure LED work at optimum temperature and output
effi
ciency (fan speed remains at a constant speed and do not ramp up or
down) NC35
Whisper mode - Fan speed reduced to appropriate amount to reduce dB levels
to >30% of the full speed + LED Max output approximately 60% of Standard
output at appropriate level to ensure LED work at optimum temperature and
output effi
ciency (Fan speed remains at a constant speed and do not ramp up
or down) NC25
Silent Mode – ideally Fans do not spin + output capped at appropriate level to
ensure LED work at optimum temperature and output effi ciency (Fan should
never switch on in this mode or change speed if they on) NC15 target level.
