Setup
17
Whatever cooling mode is selected, a thermal cutout shuts down power to the LEDs if the fixture
temperature exceeds safe limits. If this occurs, you must reset the fixture via the control menus or via
DMX, or cycle power to the fixture off and on again.
If a thermal shutdown occurs, you are pushing the fixture to its limits. Clean the fixture, particularly the air
vents, and check that there is sufficient airflow around the fixture. Consider increasing ventilation,
reducing the ambient temperature, or switching to
FULL
mode.
Dimming
DIM
allows you to select a dimming curve for overall intensity. You can choose from an optically linear
curve, a square-law curve that gives finer control at low intensity and coarser control at high intensity, an
inverse square-law curve, and an S-curve that gives finer control at low and high intensities and coarser
control at medium intensities (see Figure 6).
Display settings
The
DISP
submenu can be used to adjust the length of time the display is on before it switches off
automatically and goes into Sleep mode. You can also deactivate Sleep mode so that the display remains
on all the time.
You can set the intensity level of the display using the
DINT
submenu.The default is 100%.
Two modes are available for displaying error messages in the
ERRM
submenu. The default is setting is
normal, where error messages appear on the display at 100% intensity (regardless of what the display
intensity has been set to), and the service light illuminates. Alternatively, a ‘silent’ error mode is available,
where no error message is displayed, but the service light illuminates.
