How does this trial room work with these timed portal?

Ive tried anything i can come up but nothig has worked. There are total 3 of these circles on the room. This is one of them on thje picture.
Its the 4th ascendance trial floor room.

When you walk into it its starts to spin and at some point teleports you back. But there are no more levers in the room only this and other 2 same circles middle of flames.
