What do DRd 0-10v loads powered from an ELTS2 do?

Question:

If I have a DRd with a 0-10v (FLO) option card, with those circuits powered by an ELTS2 in an emergency situation, what does the 0-10v card do, and what levels do those circuits end up at?

Answer:

The 0-10v card becomes unpowered, which will break the control line feed, and send the 0-10v load to full. The option card must be powered and active to perform any dimming.
