Hi all. I've been given a "problem" to figure out by my supervisor.

I am running a Mori-Seiki SV-50, control FS-15M. There is a light on the top of the machine which shows green while the machine is in cycle. My manager noticed that the green light is sometimes on at other times.

I experimented with it and found that using MDI mode would cause the green light to come on, and that it would stay on till given an M30, either from a program cycled or in MDI.

He is adamant that this is a problem which needs to be fixed and I would like to satisfy him. Can anyone help me?
