This can be simply set up with two routes:

route 1 sets point 2 thrown, point 3 closed;

route 2 sets point 1 closed, point 2 closed.

The routes can be triggered by conditions - so they happen when another event occurs. In this case we want to trigger route 1 when point 1 goes to thrown, and trigger route 2 when point 3 goes to thrown. Use the "trigger route when" dialog box to program this.

the CVs that need to be set to make this happen are:

CV63=12, CV64=3;

CV75=2, CV76=1;

CV381=11, CV386=13
