I’ve seen it before where they have connected dimmers from a smaller architectural rack to stage circuits intended for work or rehearsal lighting. This allows the larger rack to remain offline, so you are not running the fans sucking in dirt.<br>
<br>
Probably the best thing to do, if you don’t already have them, is to contact ETC and provide them with the serial number (job number) from the rack.<br>
They can usually provide you with system drawings as long as the system was properly commissioned by ETC.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve had to do this in a few places over the years where when the building owners had no idea who the original installer was or connected to the system.<o:p></o:p></p>

<p class="MsoNormal">As you may know, I began my return to educational theatre last week at a small university in central Iowa and have run across something that I am confused about regarding the lighting system. It appears to be an older ETC system with a
single Sensor rack (96 dimmers). However, we are somehow driving discrete 120 circuits (there are a couple that are labeled as duplicates, but not enough to account for the 24 extra circuits)
