Selecting and setting/changing values in the operating menu; pressing the '-' and '+' keys
simultaneously takes the user back up a menu level. The congured value is not saved.
6.1 Operating functions
The operating functions of the process display unit are divided into the
following menus. The individual parameters and settings are described in
the “Commissioning” section.
If the operating menu is disabled by means of a user code, the
individual menus and parameters can be displayed but not changed. To
change a parameter, the user code must be entered. As the display unit
can only display digits in the 7-segment display and not alphanumeric
characters, the procedure for number parameters is different to that for
text parameters.
If the operating position contains only numbers as parameters, the
operating position is displayed in the 14-segment display and the
configured parameter is displayed in the 7-segment display. To edit,
press the ‘E’-button followed by the user code.
If the operating position contains text parameters, only the operating
position is initially displayed in the 14-segment display. If the ‘E’
button is pressed again, the configured parameter is displayed in the
14-segment display. To edit, press the ‘+’ button followed by the user
code.
