Security / Reliability
Protection against overheating with user-
defined temperature limits for the fans
Special heat/temperature sensors constantly monitor the temperature
within the display. NeC’s public displays in the MultiSync
®
20 series and the
MuLTeOS series contain respectively two or three fans which can be adjusted
to switch on at a user-defined temperature limit. As soon as the selected
temperature limit is reached within the monitor, the fans automatically switch
on to cool the display back down to the user-defined desired temperature.
Control of the temperature levels of the integrated heat sensors is easily
performed using the On Screen display.
Together with additional mechanisms, such as automatic brightness reduction
at extreme temperatures, the measures to protect against overheating allow
trouble-free and unbroken, continuous operation (without emergency shut-
down) even in the most difficult of environments. The longevity of the display
is therefore also ensured. (Recommended inner temperature limit is approx.
45°C).
displays without protection against overheating quickly succumb to an
emergency shut-down or power-down in order to avoid any damage. in
extreme cases the displays can even completely fail or be damaged.
With its multi-level protection systems, NeC display Solutions has solved the
problem of overheating for its public displays. Their trouble-free operation is
now assured.
