I just got back from a successful installation of a new system and about a week later the customer has informed me of this problem.


Apparently the Panelview Plus 700 had suddenly gone dim. They could still see the values, but everything was quite dark. They powered off, and after cycling the power to the panel a few times the panelview came on at full brightness.

The one concern I have is temperature. I recall the panel getting warm while the machine was running for some time (the panel is a large stainless steel panel with purge) and it is mounted near a large induction motor which it may pick up heat from. The specs on all panelviews say that they can run at 55ºC or 131ºF, and though the temperatures didnt approach this (i think) when I was there, would this be the result?

If anyone has any input on this, or maybe has seen a panelview dim like this please share.

is this normal feature (screen saver) or failure?
if it is failure, it is most likely related to background lighting, maybe just loose connection or "cold joint".

If this is true temperature could cause it. I would suggest you call Rockwell Support. Of course the first thing they are going to ask you is what is the temperature of the panel. Can you get the people there to put a thermometer in the panel and give you the temperature inside the panel when it happens?

It is not the screen saver, that was my first thought as well, and I always turn it off for this exact reason. The thermometer inside the panel was my thought as well, however this is in russia, and i had a tough enough time getting some other basic things, so a thermometer might prove to be tough. I was more wondering if anyone had seen a problem like this caused by excessive heat.
