Fan modes
The four different cooling fan modes give you a range of options to choose from
depending on how you want to allocate priority between high-intensity light output or
low fan noise:
• Fan regulated gives priority to light output and only operates fans as necessary. If the
fixture is blacked out, fans run at minimum speed. When light output intensity is
increased, temperature regulation increases fan speed to the level necessary to keep
the fixture at optimum temperature.
If light output is set to maximum intensity but the fans can keep the fixture at optimum
temperature, there will be no regulation of light intensity. If the fixture begins to
exceed optimum temperature, light intensity will be limited until optimum
temperature can be maintained.
• Fan constant high mode is optimized for maximum light output and suits operation in
high ambient temperatures. Fans are set to constant operation at high speed. Light
output intensity is limited smoothly if it becomes necessary in order to keep fixture
temperature at optimum level.
Besides maximizing light output in high ambient temperatures, you can use this mode
to cool down a fixture quickly or to remove dust from cooling fans.
• Fan constant medium sets fans to constant operation at medium speed. Light output
intensity is reduced to a level where it will normally remain constant at ambient
temperatures of up to 45° C (113° F). Intensity is smoothly limited further if it becomes
necessary in order to keep fixture temperature at optimum level.
• Fan constant low mode sets fans to constant operation at low speed and is optimized
for minimum noise. Light output intensity is reduced to a level where it will normally
remain constant at ambient temperatures of up to 30° C (86° F). Intensity is smoothly
limited further if it becomes necessary in order to keep fixture temperature at
optimum level.
In all fan modes, if fixture temperature reaches a dangerous level, LEDs will be shut
down for a period until the fans have brought the temperature down to a safe level.
You can set the cooling fan mode using the control panel or the Special / Control DMX
channel.
Effect wheel shortcuts
By default, the color wheel and gobo wheels take the shortest, fastest route from one
slot to the next, even if this means that they may pass through the open position. To
avoid the wheels passing through the open position when they change from one slot
to the next you can set Effect shortcuts on the Special / Control DMX channel to OFF.
Behavior when the fixture is not receiving a DMX signal
You can set the fixture to react in four different ways if no DMX signal is present (if the
fixture is being controlled by DMX but the DMX signal stops, or if you apply power to
the fixture when no DMX signal is present):
• Hold sets the fixture to continue obeying the last DMX values it received. This is the
default setting.
• Blackout sets the fixture to black out whenever it is not receiving a DMX signal.
