Important! To ensure correct operation of the displays, the standby
switch should be set to the ON position when using DMX.
DMX may be used without changing any of the settings on the main
control panel. When the system detects a valid DMX data stream on the
input, the control will default to the DMX system levels. Any attempt to
control the machine from the control panel will have no effect until the
DMX signal is removed. Though it is impossible to operate the machine
from its control board while using DMX512, the displays will show the
current input values for Fog and Density.
DMX control uses two channels:
Channel 1
controls level of fog output.
Channel 2
controls the density of the fog, by adjusting the speed of the
fan that pushes the fog out.
For detailed information refer to “DMX protocol” below.
The system implements true proportional control of the fog output rather
than the simple switching functions found on other equipment. The output
levels of FOG and FAN are linked during DMX operation via the Density
setting.
The machine uses a 'pump ramping' technique to allow continuous
operation. This means that transmitting DMX 100% will cause the
machine to run at full output until the temperature falls and the output is
automatically reduced. The output will remain at this level until the DMX
signal is reduced, or the fluid is exhausted. There is no possibility of
damage, since the electronic fluid level sensor will shut the machine down
(if local fluid supply is used). The fan output level is affected by the
ramping system via the Density setting.
Note!
The onboard timer functions are not accessible via the DMX
system. Any timing of the output must be done using the
programming capabilities of the DMX console.
