2.3 Operation and data input
Menu selection
The numerical keypad is used for activating a menu and for entering
data. They are displayed differently depending on the operating mode.
 During setup, Teach-in mode etc., the functions are shown in a 9-
field box, the menu window. The meaning of the selected symbol
/ menu item is described in the footer.
 In other operating modes, the keypad symbol is shown with the
position of the function marked (see figure).
Press the corresponding numerical key, or move the highlight with the
arrow keys to the symbol on the screen and press the ENT key.
Soft keys
 With some system functions, the available functions are arranged
on several soft-key levels.
 Some soft keys work like “toggle switches.” A function is active
when the associated field in the soft-key row is highlighted in color.
The setting remains in effect until the function is switched off again.
 With functions like Take over position you do not have to enter
values manually. The data are automatically written into the
appropriate input fields.
 Data entries are not concluded until the Save or Input finished soft
key has been pressed.
 The Back soft key takes you back to the previous operating level.
