ACCLAIM LED CYC

All Vari-lite and Strand lighting luminaires are governed by the same fan
speed versus noise levels and maximum power output rules as detailed
below. The noise related to these levels conforms to noise criteria levels
detailed within the document.
There are three control parameters that can can be selected separately or
in conjunction when permitted to manage fan speed versus noise levels
and maximum power output.
NOTE:
Not all fi xture have all modes or functions. Refer to DMX map and/
or user interface menu tree to verify the modes and functions in your
fi xture.
FAN VERSUS OUTPUT PRESET MODES
These modes are selectable at either / or the fi xtures DMX control chan-
nel or via the fi xture user interface screen.
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 set-
ting). 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 out-
put 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.
