Kawasaki AD-controller SIG buttons activation?

We have Kawasaki JS-6 robot with AD controller. I have installed two axis welding positioner that is used by 4 digital outputs. To ease teaching I would like to be able to command these outputs with TP buttons SIG A-D. I have configured these buttons at system data to robot IO'S. But nothing happens when I push these buttons when robot is in teach mode. What am I missing here?

Yes I know these are getting rare. But now it is working and until it does I will be using it. When it breaks down so that it cannot be easily repaired I will probably throw it into trash bin Sogic??
