RIA16 Function and system design
Endress+Hauser 7
3 Function and system design
The field indicator is directly looped into the 4 to 20 mA measuring circuit. The energy required is
taken from the loop of the measuring circuit. The device records an analog measured value and
displays it on a clearly legible LC display. In addition, a bargraph displays the measured value
graphically. The illuminated display makes it easier to read the display in dark surroundings.
4 Installation
4.1 Incoming acceptance, transport, storage
The permitted ambient and storage conditions must be observed. The precise specifications can be
found in Section "Technical data".
4.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Are the packaging or contents damaged?
• Is anything missing from the delivery? Compare the scope of delivery with the information you
specified in the order. See also section 2.2 "Scope of delivery".
4.1.2 Transportation and storage
Note the following points:
• Pack the device so that is protected against impact for storage and transportation. The original
packaging provides optimum protection.
• The permitted storage temperature range is -40 to +80°C (-40 to +176 °F); it is possible to store
the device in the limit temperature ranges for a limited period (maximum 48 hours).
4.2 Installation conditions
The process indicator is designed to be used in the field.
The orientation is determined by the readability of the display. Cable entries are located on the
bottom of the device.
Operational temperature range:
-40 to +80 °C (-40 to +176 °F)
-20 to +80 °C (-4 to +176 °F) when the Open Collector output is used
!Note!
If the device is operated in the upper temperature limit range, this reduces the operating life of the
indicator.
The display may react slowly at temperatures below -20 °C (-4 °F).
Readability of the display cannot be guaranteed at temperatures below -30 °C (-22 °F).

6.4 Configuration via interface & FieldCare Device Setup
PC configuration software
#Warning!
The device must be configured outside the hazardous area.
"Caution!
The device can assume undefined states while configuring with FieldCare! This can result in the
undefined switching of outputs and relays.
To configure the device with the FieldCare Device Setup software, connect the device to your PC.
You need a special interface adapter for this purpose - the Commubox FXA291 (see Chapter
’Accessories’).
The 4-pin connector of the interface cable must be plugged into the corresponding socket inside the
device and the USB connector must be plugged into a free USB slot on the PC.
Connection establishment
When connecting the device, the device DTM is not automatically loaded in FieldCare, i.e. the
device has to be added manually.
• Firstly, add the Communication DTM "PCP (Readwin) TXU10 / FXA291" to an empty project.
• In the Comm DTM settings, set the baud rate to 2400 baud and select the COM-port used.
• Add the RIA14/16 Version Vx.xx.xx device DTM to the project using the "Add device..."
function.
!Note!
Online configuration is not possible with the RIA14/RIA16.
• To then configure the device itself, follow these Operating Instructions for the device. The entire
Setup menu, i.e. all the parameters listed in these Operating Instructions, can also be found in the
FieldCare Device Setup.
a0011272-en
Fig. 11: Configuring the field indicator via interface adapter
!Note!
In general, it is possible to overwrite parameters with the FieldCare PC software and the appropriate
device DTM even if access protection is active.
If access protection by means of a code should be extended to the software, this function should be
activated in the extended device setup.

Measured value decimal point
'DI DP'
Indicates the number of places after the decimal point for the numerical display of the
measuring range.
– Selection range 0 - 3 places after decimal point
– Default: 1 place after decimal point
If the number of spaces after the decimal point is increased, the value for all the
dependent operating parameters must be recalculated based on the formula new value
= old value * 10PDnew - PDold. If the value of one of the dependent operating parameters
is < -19999 or > 99999, the number of places after the decimal point cannot be
increased and error message C561 is shown on the display.
Measured value 0 % 'DI LO' Indicates the display value for the 4 mA value.
– Value range -19999 to 99999
–Default:0.0
Measured value 100 % 'DI HI' Indicates the display value for the 20 mA value.
– Value range -19999 to 99999
– Default: 100.0
Measured value offset 'OFFST' This is used to correct the display measured value. The offset is added to the measured
value.
– Value range -19999 to 99999
