Function Blocks (abbreviated as: AFBs). Owing to this modular design principle, each device can be optimally adapted to individual requirements. The enCore FC1 belongs to the enCore Flow Computer device series (in short: enCore FC). This series comprises several different device types that are used as industrial process computers for special tasks for measuring gas and liquids.

2 About this Technical Documentation 2.1 About the Documentation on Hand This technical documentation is part of the enCore FC1 manual; it briefly describes the properties of the enCore FC1 flow computer being relevant for the use of the device in legal metrology.
About this Technical Documentation 2.2 The enCore FC1 Manual at a Glance The FC1 manual has a modular structure; it is made up of several volumes. Apart from the documentation on hand, all other single volumes of the manual cover all devices of the enCore FC series; they are therefore independent of the device type.

4 FC1: General Information 4.1 FC1: General Device Description The enCore FC1 flow computer is an electronic conversion device for meas- uring and calculating the flow of natural gas or, in special applications, indus- trial gas or gases with a fixed composition. Different measurement devices are to be connected to the flow computer (gas meters, pressure transmitters, temperature transmitters and, optionally, gas quality measurement devices).

An alarm is an error event affecting the legally relevant functionalities severely; the calculation of the fiscal results is stopped. In case of a warning, a minor error has occurred but the calculation of the fiscal results is continued. enCore FC1 Use in Legal Metrology Page 25 of 61...
5.3 Display and Navigation 5.3.1 Display Test The enCore FC1 provides a display test functionality to check that the dis- play functions correctly. For starting the display test, you have to activate the button in the device's home display at first. The information display is evoked. The display test can be started by activating the Display test hyperlink.
If an AFB has been assigned to a structuring folder in this way, the name of the related folder appears as a hint when selecting the correspond- ing button on the screen. enCore FC1 Use in Legal Metrology Page 27 of 61...
Most displays show measurement results, status information or settings. An underlined text element always represents a hyperlink, e.g. a reference to another display showing further details. Actions are also marked as hyperlinks in the FC1 display. Page 28 of 61 Use in Legal Metrology enCore FC1...

1.3 Type plates For the design of the type plates there are two alternatives differing slightly in label size and arrangement. Figure 3 shows the first and Figure 4 the second alternative. In the second alternative, a 2D code can be applied on the left part of the type plate optionally.
Figure 5 and Figure 6 show the FC1 front markings for both Elster and Honeywell design in case of a device with a housing width of 1/2. As there is more free space on the front plate in 1/2 housing width, the exact positioning of the type plates in practice may also deviate from Figure 5 or Figure 6.

4 Sealing of Process Connectors For fiscal use, the connectors of legally relevant process boards have to be officially secured. Plug-in connectors with screws are used for connecting the lines of the ExMFE5 and the MFE7 board. Sealing of ExMFE5 connectors In case of an ExMFE5 board, there is only one connector for all lines.
