9.14.1 Operating functions
The operating functions of the process indicator 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.
• Setup (SETUP)
Basic device settings
• Diagnostics (DIAG)
Device information, display of error messages
• Expert (EXPRT)
Expert settings for device setup. The Expert menu is protected from editing by an access
code (default 0000).
9.14.2 Operating modes
The process indicator can be used in two different operating modes:
• 4 to 20 mA mode:
In this operating mode, the process indicator is incorporated into the 4 to 20 mA current
loop and measures the transmitted current. The variable calculated based on the current
value and range limits is displayed in digital form on the 5-digit LCD. In addition, the
associated unit and a bar graph can be displayed.
• HART mode:
The indicator is powered via the current loop.
The device can be adjusted under the "Level" menu (see operating matrix). The measured
value displayed corresponds to the measured level.
HART communication operates according to the master/slave principle.
For additional information, see BA01170K.
9.14.3 Operating matrix
After power-up:
‣
Press the key twice
 The "Level" menu is then available
Using the following operating matrix, a display in percent can be set. To do this, select
"Mode" parameter => 4-20 and "Unit" parameter =>%
The LEVEL menu is only visible if the RIA15 has been ordered with the "Level" option
and the indicator is operated in the HART mode (MODE = HART). The basic settings
for the device can be made via the RIA15 with this menu.
