Clarity SN-4620-1080 manual 117

the top of the array experience a higher ambient tem- perature and overheat.

Should the thermal ratings be exceeded, the most likely visible affect will be that the display may start to ‘clear’ which means the LC material within the display starts to lose its light altering properties and off-color or black voids will start to be visible in the display. This is not destructive to the display and will correct itself once the thermal issue is adequately addressed.

WARNING

Chronic overheating may shorten the unit lifespan and void your warranty.

In each case, either moving the display away from a heat or light source, providing shielding from that source, or providing additional ventilation to ensure against heat buildup should be sufficient to address the thermal issue.

A built-in thermal sensor on the display electronics (see “Internal Temperature” on page 85) which can be moni- tored in the UI and through RS232. While not directly cor- relating to the ambient temperature, it can be used to determine if changes to the displays environment have had a positive or negative effect. It can also be used to thermally map a large group of displays to determine if some are run- ning significantly warmer or cooler than the others.
