RIA46 Commissioning

7 Commissioning

7.1 Post-installation check and switching on the device

Make sure that all post-connection checks have been carried out before putting your device
into operation:

• "Post-installation check" checklist →  11

• "Post-connection check" checklist →  15
After the operating voltage is applied, the green LED lights up and the display indicates

the device is ready for operation.
If you are commissioning the device for the first time, program the setup as described in

the following sections of the Operating Instructions.
If you are commissioning a device that is already configured or preset, the device starts

measuring immediately as defined in the settings. The values of the channels currently
activated are shown on the display. Changes to the display can be made in the Display
menu item →  33.

Remove the protective film from the display as this would otherwise affect the
readability of the display.

7.2 General information about configuring the device

You can configure your device onsite or put it into operation using the three integrated
keys or via the PC. You require the Commubox FXA291/TXU10 (see the ‘Accessories’
section) to connect the device to a PC.

Advantages of configuring via FieldCare Device Setup:

• The device data are saved in FieldCare Device Setup and can be retrieved at any time.

• Data entry is faster with the keyboard.

9. Confirm the last position of the code in order to exit the menu. The full code is
displayed. Press + to scroll back to the last item of the x Back submenu and confirm
this item. By confirming the point, the value is adopted and the display returns to the
Setup level. Again select the last parameter x Back to also exit this submenu and
return to the measured value/channel display level.

The x Back item at the end of every picklist/menu item takes the user from the
submenu to the next menu level up.

7.4 Device configuration

Configuration steps:

1. Selection of the application conditions (only for 2-channel device) →  24

2. Configuration of the universal input(s) →  26

3. Configuration of calculations →  27

4. Configuration of the analog output(s) →  28

5. Configuration of the relays (if option selected); assignment and monitoring of limit
values →  28

6. Advanced device configuration (access protection/operating code; backup of current
setup/user setup) →  32

7. Configuration of display functionalities →  33

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
→  25, only available in the two-channel version). If you want to configure a single­channel device, please proceed as described in Step 2 →  26.

7.4.1 Step 1: Selecting the application conditions/number of active input channels

Application conditions for two-channel device

Call up the Setup menu after performing the post-installation check.
Press E → press + → Setup is displayed → press E.
Select your application conditions in the first item of the setup. You have a choice of the

following settings:

• Differential pressure (Diff pressure): application package; parameters are automatically

preselected for you.

• One-channel (1-channel): universal input 2 (Analog in 2) is deactivated (off) in the

software. The second channel can be subsequently activated any time via Setup →
Analog in 2 →  26.

• Two-channel (2-channel): universal input 1 (Analog in 1) and universal input 2 (Analog

in 2) are pre-configured with the following values:
– Signal type: Current
– Signal range: 4-20mA

A full description of the "Differential pressure" application package is provided in the
following section.

To set up the device in single-channel/two-channel applications, please proceed with the
device setup as explained in Step 2 →  26.

If the application or the selected parameter are subsequently changed, parameters
already configured are retained (e.g. if the differential pressure application is changed
to two-channel, Calc value 1 remains set to Difference).
