Structure of the menus 

 
In accordance with the big function-variety of the PT50, there are many parameters for the adaptation of 
the controller to the tasks. To facilitate the survey the parameters of the same functions are merged in 
sub menus. 
 
Which  submenus  are  available  in  each  of  the  main  menus  can  be  selected  with  help  of  the  service-
program on the PC. Therefore it is not possible to describe here a main menu layout, but the table be-
low shows all available sub menus. 
 
 

Following sub menus can be included in the main menus:
