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.
• Stand-Alone sets the fixture to play its stored stand-alone scene (see DMX Shot below)
when the fixture is not receiving a DMX signal. If no stand-alone scene is stored in
memory, the fixture will black out.
• DMX Shot takes a snapshot of the DMX values that are currently being received and
stores them in the fixture's memory as its stand-alone scene. The fixture will display this
stand-alone scene if it is set to Stand-Alone (see above) and is not receiving a DMX
signal.
You can select one of the four settings above using either the control panel or the
Special / Control DMX channel.
Stand-Alone operation
If the fixture is set to Stand-Alone and if a stand-alone scene has been stored in its
memory using the DMX Shot command, it will display its stand-alone scene at all times
when it is powered on but not receiving a DMX signal. You can therefore use this
setting if you want fixtures to automatically start stand-alone operation when you
apply power to them.
