Cooling Kit
For outdoor applications, a cooling kit may be desired to prevent excessive heating of the LCD display.
In direct sunlight, the front surface of the display (the LCD cell) may reach temperatures well above the
ambient temperature. Possible effects of extreme surface temperatures include:
• LCD polarizer damage (permanent degraded image)
• LCD fluid clearing (display unreadable)
• Latent image (image burn-in visible)
• Flicker (image jitter)
• Localized non-uniformity (permanent spotty appearance).
The cooling kit consists of a rear-mounted housing containing three fans and a front-mounted baffle
that channels the air flow across the display surface. The fans' speed is governed by a temperature sen-
sor adjacent to the photo sensor that is mounted on the front of the monitor. At temperatures above
15°C the fans will turn on at low speed and reach maximum speed at 25°C, thus minimizing the effects
of sun loading and high temperatures.
The total fan kit power consumption is approximately 3.6 watts with fans at max speed. Fan power is
derived from the 12V input (4-pin DIN connector.)
All cooling kit version monitors are shipped with the cooling kit pre-installed.
