Press ‘E’ Épress ‘+’ É‘Setup’ is displayed, press É‘E’.
Select your application conditions in the first point of the setup. The following options are available:
1. Differential pressure (‘Diff press’): application package; parameters are automatically
preconfigured for you.
2. Single channel (‘1-channel’): universal input 2 (‘AnalogIn 2’) is deactivated (‘off’) from the
software side. The second channel can always be activated at a later stage via ‘Setup’É‘AI
2’ (→Chap. 6.4.2).
3. Two channels (‘2-channel’): universal input 1 (‘AnalogIn 1’) and universal input 2
(‘AnalogIn 2’) are preconfigured with the following values:
– Signal type (‘Sign type’): ‘current’
– Signal range (‘Sign range’): ‘4-20mA’
The following section provides a detailed description of the "Differential pressure" application
package.
To set up the device in single-channel/two-channel applications, please proceed with the device
setup as explained in Section 6.4.2 (analog input 1 (‘AnalogIn 1’)).
!Note!
If the application or the parameter selected are subsequently changed, parameters already
configured are retained (e.g. if the differential pressure application is changed to two-channel É
‘Calc Value 1’ remains at the Difference parameter).

RIA46 Commissioning
Endress+Hauser 19
Differential pressure application
A concise setup is available for differential pressure applications.
Once the differential pressure application setup has been successfully completed, the configured
parameters of the analog inputs and the linearization points are used to automatically form the
difference between the two inputs and linearize the signal. As a result, the volume is already shown
on the display (= calculated value 2).
"Caution!
The following is essential to ensure values are calculated correctly and that the setup functions
properly:
• Sensor returning the higher pressure: connected to analog input 1 (‘AnalogIn 1’)
• Sensor returning the lower pressure: connected to analog input 2 (‘AnalogIn 2’)
a0010350
Fig. 8: Differential pressure application
Setup ÉApplication ÉDiff pressure
After selecting the differential pressure application by confirming the "Diff press" parameter, the
parameters, which are displayed in succession and can be edited, must be configured individually
for your application.
Some parameters are already configured for you by selecting the application setup (→ä20).
The parameter “CV Factor” serves for the regard of the density of the medium at level
measurement, i.e. it equates the mathematic formula 1/(density*gravitational acceleration). The
standard value of the factor is 1.
At this the density is to be named in kg/m3and the pressure in Pascal (Pa) or N/m2. The
gravitational acceleration is defined by the constant on the earth’s surface.
It amounts g=9.81m/s2.
Tables and examples for the conversion of application related units into the defined values kg/m3
and Pa respectively N/m3 can be found in the appendix, →ä47.
!Note!
If you want to activate other parameters (see Step 4, 5, and 6 or offset for analog inputs, change
display options, display original values of analog channels, etc.), you can do so afterwards in the
setup of the corresponding parameter.

6.4.2 Step 2: Configuring the universal input(s) (‘AnalogIn 1/2’)
The device has one universal input, and optionally another universal input for current (‘current’),
voltage (‘voltage’), resistance thermometer (‘RTD’) or thermocouples (‘TC’).
The input is monitored for a cable open circuit (see "Measuring range limits" table (→ä32) and
"Troubleshooting" section (→ä35).
Minimum/maximum values at the inputs:
Each universal input saves the smallest and biggest measured value measured. These values can be
reset individually for every channel. In the setup, the administrator can decide whether a user can
reset the minimum and maximum values of the individual channels directly in the main menu
without the need for a release code. It is reset in the event of a PRESET and if the scaling of the
channel is changed.
!Note!
The current min./max. value is saved every 15 minutes. If the power supply is disconnected (mains
off/mains on), a gap in the recording may result. The measuring interval starts when the device is
switched on. It is not possible to synchronize the measuring cycles to full hours.

Create the linearization table:
If the volume value should be calculated - i.e. a linearization of the difference is
output - the X and Y coordinates have to be specified as the basis for performing the
calculation.
‘No lin points’: number of linearization points required (max. 32)
‘X-value’: X-coordinate for linearization point X1, 2, ...
‘Y-value’: Y-coordinate for linearization point X1, 2, ...
CV Factor Factor for the regard of the density of the medium at level measurement, i.e. it
equates the formula 1/(density*gravitational acceleration); Standard value: 1
