6 NEBULA OPERATION
The minimum setting can be used to keep lamp filaments warm for fast response time, or for example to maintain lighting
at a minimum level of illumination, a requirement often needed by orchestra lighting and working lights.
The maximum setting can be used for example to prolong lamp life, which is very sensitive to over-voltage conditions. For
this reason, the maximum setting has higher priority than the minimum setting.
As both Minimum and Maximum levels may be set to anywhere from Off to Full, care needs to taken in setting these levels.
Dimmer curves
Each dimmer in the Nebula may be set to a number of dimmer curves. Curves fitted as standard are:
Incandescent: The Incandescent dimmer curve is suitable for most Theatre and TV applications using incandescent bulbs
whether normal tungsten or tungsten halogen type. The curve is specially tailored to provide linear apparent light under these
conditions.
Non-Dim: The Non-Dim curve selection is for use with loads which must be switched on and off, such as motors, smoke
machines, and other effects. Each dimmer using the Non-Dim curve switches on at a user programmable Non-Dim level (see
below): any control level at this level or above will switch the dimmer to Full instantly. Once On, the dimmer will stay on until
the control level goes 5% below the Non-Dim level. An "All" function allows all Non-Dim switch levels to be set at the same
time. The Non-Dim facility may be combined with the Minimum and Maximum settings to switch the dimmer output between
any two selected output voltages.
Television: A modified Incandescent dimmer curve suitable for adjusting the colour temperature of incandescent bulbs in
TV or Film studios. This curve is not intended to used as a linear dimming curve.
Fluorescent: This curve is suited to dimming mains ballasted fluorescent lamps fitted with filament transformers and pulse
ballasts. The flicker apparent at low dim levels can be controlled by setting the Off level (see below).
Neon: This curve is suited to dimming neon discharge tubes fitted with pulse ballasts. The flicker apparent at low dim
levels can be controlled by setting the Off level (see below).
Linear Power: This dimmer curve outputs linear RMS power against DMX level for use when the Nebula is used to control
heating elements in ovens etc.
Linear Phase Angle: This dimmer curves outputs linear phase angle against DMX level.
The "All" function allows all dimmer curves to be set at the same time. Each dimmer can also be flashed instantly to Full for
identification. Other curves, or custom dimmer curves may be included by arrangement with Theatrelight.
