6.4 Configuring the device
Configuration steps:
1. Select the application conditions (only for 2-channel devices) (
→
Chap. 6.4.1)
2. Configure the universal input(s) (
→
Chap. 6.4.2)
3. Configure the calculations (
→
Chap. 6.4.3)
4. Configure the analog output(s) (
→
Chap. 6.4.4)
5. Configure relays (if option selected); assign and monitor limit values (
→
Chap. 6.4.5)
6. Advanced device configuration (access protection/operating code; saving the current setup/
user setup) (
→
Chap. 6.4.6)
7. Configure the display functions (
→
Chap. 6.4.7)
The following section provides a detailed account of how to set up the two-channel device and the
differential pressure application package (brief overview of the configuration

22, only
available in the two-channel version). If you want to configure a single-channel device, please
proceed as explained in Section 6.4.2.
6.4.1 Step 1: Selecting the application conditions/number of active
input channels
Application conditions of a two-channel device
Call up the Setup menu after performing the post-installation check.
Press ‘
E ’
É
press ‘ + ’
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 pressure ’): application package; parameters are automatically
preconfigured for you.
2. Single channel (‘ 1-channel ’): universal input 2 (‘ Analog in 2 ’) is deactivated (‘ off ’) from the
software side. The second channel can always be activated at a later stage via
‘
Setup ’
É
‘Analog in 2’ (
→
Chap. 6.4.2).
3. Two channels (‘ 2-channel ’): universal input 1 (‘ Analog in 1 ’) and universal input 2 (‘ Analog
in 2 ’) are preconfigured with the following values:
– Signal type (‘ Signal type ’): ‘ Current ’
– Signal range (‘ Signal 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 (‘
Analog in 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).
