I don't think the bottom board has the logic to cycle between F-N-R by itself.  You can jumper them to go in one direction, but you have to change the jumpers to go the other way.  Here's a post by GGG, he knows more about these boards than I do for sure.

If you look at the board on a table in front of you and the relay and diodes on your right.  The header that is closest to you  is where the jumpers would go.  If you jumper the 2 slots to the far left (position 1 and 2 as example) you get one direction, if you remove that jumper and place it into the next 2 (3 and 4) you get the opposite direction.

The difference between QSI board or a DCRU is that it had the logic chips to do electronic sequencing.  PS-1 bottom board doesn't have the logic chip so the top board does the sequencing.  Those header positions are the same.   G
