hi K.Ljungberg,

U = A      Und = And

E = I        Eingang = Input

A = Q      Ausgang = Output

There are also some differences in some instructions.

Have a look to this FAQ:

What are the differences between German and English mnemonics?

 hope this helps,

regards,

 HI thanks i did figure it out, on my own, 

i refared to that manual, if you look at it you cant find it there.
