STT 300

3.1. Control system

The control system is switched on at the main switch. The control system is operated via a ”selection window” and the keyboard of the operator panel.

The facility’s control system is factory-programmed. Nevertheless, you have to set specific values (basic parameters) which are dependent on the processed material, for instance.

The values entered are stored in the control system and remain so, even after the unit is switched off or in the event of a power cut. All messages are displayed in plain text.

In describing this start-up, we have assumed that the various sub-menus are selected from the ”table of contents”.

This structure of the description has been selected since, in most cases, you will only work on one item in the ”submenu”.

If you want to work on several ”submenu” items in succession, you can select the individual items directly by means of the arrow keys.
