PC software supporting all enCore devices along with a number of other Elster devices. The enSuite software provides tools for configuration, parameterization, diagnosis, software downloads and other services.
2 About these Instructions Part 4 of the enCore FC1 manual has a modular design and consists of individual volumes which document an Application Function Block . The advantage of this feature is that you can specifically compile documents of those AFBs used in your application.
You can download all parts of the FC1 manual in PDF format from our Docuthek (www.docuthek.com). The documents are regularly updated. 2.1 The enCore FC1 Manual at a Glance The manual FC1 is made up of four parts: • Part 1: Brief Instruction The first part describes the legally relevant properties of the FC1 flow computer in brief.
2.2.1 Presentation of Instructions Safety instructions Safety instructions include notes and information which if disregarded may lead to functions not working correctly or not working at all. Page 8 of 53 Flow Conversion AFB enCore FC1...
