1 General Information

1.1 The enCore/enSuite Concept

enCore is the name of an Elster product platform for advanced measure-
ment devices. All enCore devices are based on the same hardware components and software concepts. Both the hardware and software of enCore devices have a modular design; the configuration of the process board equipment and the arrangement of software components are variable. On one hand, the software components consist of basic functionalities, which are provided by the Basic System with its System Function Blocks
(abbreviated as: SFBs), and on the other hand consist of application-related functionalities, which come with different Application Function Blocks
(abbreviated as: AFB). Owing to this modular design principle, each device can be optimally adapted to individual requirements.
enSuite is the name of the 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.
Parameterization in enSuite
Please note that the changes that you make in parameterization of enSuite become active in the device only when you activate the action Transfer parameterization to device and after the enCore
device restarts (automatically).

3 Security considerations for your network

enCore FC devices are used in modern accounting infrastructures and network control technology with the task of transmitting process information such as counters, measurements and messages to an accounting center or control station. Such a connection represents a significant security risk and therefore careful consideration must be given to the design.
Reporting a security issue to Honeywell
As soon as you encounter a possible security gap of a Honeywell product, please report it directly to Honeywell.
FAQs 11.1 How to report a security vulnerability to Honeywell? (p. 116)
Enforce a strong password policy
here are different attacks on passwords today, so you should follow the
T best practices for managing your passwords. Here are some of the best practices:
Always change default passwords.
Choose strong passwords.
Use a combination of uppercase and lowercase letters, numbers, and special characters when assigning a password.
In addition, protection increases with the password length. A strong password consists of at least 8 characters.
Document deviations of the best practices
If the system does not allow one of the best practices to be followed this should be documented. For example: maybe you do not allow the special character "=" in the password.
Security considerations for your network 3
Page 22 of 120
Operating Instructions
enCore FC
Preventing unauthorized external access using a firewall
To reduce the risk to your network, we highly recommend to include a firewall or some other mechanism to limit the network traffic between the (external) central accounting center resp. control station and the (internal) network of the gas measuring plant.
Furthermore, we recommend to allow protocols and ports only that are actually used for data exchange with the external network, e.g. by adding these to the white list of the firewall ( 10.5.1 Data protocols and its TCP
default port (Ethernet), p. 113).
For example:

4 Safety

4.1 General Safety Instructions

WARNING!
Risk of explosion
A risk of explosion exists if the enCore FC device (FC1 or MC1) is improperly assembled and connected!
The enCore FC device must be installed outside of Ex zones 0, 1 and 2.
Assemblies which are authorized as associated category ib electrical equipment with intrinsically safe electrical circuits in accordance with EN 60079-11 can be installed in the enCore FC device, e.g. input boards with the label ExMFE5. The enCore FC device is therefore suitable for connecting to transmitters, pulse and signal sensors that are located in the potentially explosive area e.g. in zone 1. A mixed connection of intrinsically safe and non-intrinsically safe circuits is not permitted for these assemblies.
Only measurement transmitters and pulse sensors that follow at least the requirements of the intrinsically safe protection class [Ex ib Gb] II C may be connected to the ExMFE5 assembly terminals provided for that purpose.
When using input boards of ExMFE5 type, it is not permitted (according to the EC type examination certificate ATEX) to include more than one ExMFE5 board (i.e. more than one associated apparatus) into the same intrinsically safe circuit.
All signals from the potentially explosive area (zone 0, zone 1, zone 2) must be regulated using suitable Ex isolators if they are connected to some other assembly group that is not the input board ExMFE5.

Operating Instructions
enCore FC
The regulations in the relevant standards, especially EN 60079-0, EN 60079-11, EN 60079-17 and EN 60079-25, must be obeyed unconditionally.
Safety and warning instructions
The following safety and warning instructions must be observed unconditionally:
Any individual appointed to perform work on or with the enCore FC device must read and understand these Operating Instructions before beginning work. This also applies if the individual concerned has already worked with such a device or a similar one, or was instructed by the manufacturer.
In order to avoid risks and to ensure that the enCore FC device performs in an optimal manner, no changes or modifications that were not expressly authorized by the manufacturer may be performed on the device.
The enCore FC device must not be exposed to temperatures below 25°C or above +60°C during storage.
A temperature that is between 10°C and +55°C must be en- sured while the enCore FC device is being operated.
The power supply in enCore FC device is over a 24 V DC, and this supply must be protected externally using a 1A time- delay fuse.
The grounding system is connected to the power supply socket PE for potential equalization.
The threshold values listed in the certificates of conformity (e.g. EC type examination certificate ATEX) for the boards to be connected to the device must be observed.
The threshold values that are listed in the certificate of conformity for the applicable authorization must be observed while using the device within the scope of legal metrology e.g. of EU type examination certificate (MID).

Available Process Boards (p. 40).

4.2 Intended Use

The enCore FC device is designed and constructed exclusively for its intended use as described here.
All enCore FC devices are process computer which process information on the externally connected measurement devices and signal sensors.
The specific intended use varies according to device type:
enCore FC1
The FC1 is mainly used for (fiscal) gas measurement. In this case, the main task of the device is to convert the gas volume measured at the measurement conditions to base conditions (volume conversion). Moreover, the corresponding thermal energy and mass can be calculated. The measured and/or calculated data can be recorded and monitored.
The FC1 can also carry out other functions and calculations depending on the scope of application (e.g. volume or mass flow conversion for liquids).
Moreover, the FC1 can also be used to measure, record and monitor other process signals.
enCore MC1
The MC1 is a process computer, which processes the information from the connected external measurement devices and signal sensors. This device type is mainly used in industrial gas measure- ment. The main tasks of the device are monitoring and controlling processes. The measured and/or calculated data can be recorded and archived.
Safety 4

Operating Instructions
enCore FC
Compliance with all the specifications in these Operating Instructionsalso falls under the device's intended use.
Any use of the enCore FC that goes beyond or deviates from its intended use is considered a misuse of the device, and may lead to hazardous situations.
Claims of any kind due to loss resulting from non-intended use of the device are excluded.
Adhering to age and profession-specific regulations
When selecting a personnel, make sure to comply with the specific regulations of the overall gas system that concern age and occupation.

4.3 Unacceptable use while Impaired

Individuals whose ability to react is impaired, e.g. because of drugs, alcohol or medication, are not permitted to operate, assemble and configure the device. The operator is responsible for the careful selection of the personnel.

4.4 Operator Liability

The enCore FC is used in industrial applications. The operator of the device is therefore subject to legal obligations of occupational health and safety.
In addition to the safety instructions in these Operating Instructions, current regulations of safety, accident prevention and environmental protection must be observed for the enCore FC area of application.
The following items especially apply:
The operator must ensure compliance with the current regulations of safety, accident prevention and environmental protection that apply for the overall system in which the enCore FC is integrated.
The operator must keep himself or herself informed of the applicable occupational health and safety regulations, and determine, over the course of a risk assessment, the additional

Operating Instructions
Page 41 of 120
WARNING!
Risk of explosion
A risk of explosion exists if the enCore FC (FC1 or MC1) is improperly assembled and connected!
The enCore FC must be installed outside of Ex zones 0, 1 and 2.
Assemblies which are authorized as associated category ib electrical equipment with intrinsically safe electrical circuits in accordance with EN 60079-11 can be installed in the enCore FC, e.g. input boards with the label ExMFE5. The enCore FC is therefore suitable for connecting to transmitters, pulse and signal sensors that are located in the potentially explosive area e.g. in zone 1. A mixed connection of intrinsically safe and non-intrinsically safe circuits is not permitted for these assemblies.
Only measurement transmitters and pulse sensors that follow at least the requirements of the intrinsically safe protection class [Ex ib Gb] II C may be connected to the ExMFE5 assembly terminals provided for that purpose.
When using input boards of ExMFE5 type, it is not permitted (according to the EC type examination certificate ATEX) to include more than one ExMFE5 board (i.e. more than one associated apparatus) into the same intrinsically safe circuit.
All signals from the potentially explosive area (zone 0, zone 1, zone 2) must be regulated using suitable Ex isolators, if they are connected to some other assembly group that is not the input board ExMFE5
The regulations in the relevant standards, especially EN 60079-0, EN 60079-11, EN 60079-17 and EN 60079-25, must be obeyed unconditionally.

ATTENTION!
Risk of short circuit
The enCore FC device can be damaged if lines are connected while the device is connected to the power supply.
Always make sure the enCore FC is free of voltage before making any changes to device wiring or before connecting sensor, supply, signal or data lines.
The transmitter, pulse, signal and data lines are connected to the enCore FC by using plug-in screw terminals that are located in a cable housing. Fixed screw terminals are used for the power supply connection.
Special attention must be paid to the intrinsically safe electrical circuits. Before switching on the power supply, the operator must ensure that the plug connections for the gas meter, pressure and temperature inputs of the ExMFE5 input board are inserted, since this is the only way the minimum distance of 50 mm required in the relevant guidelines can be maintained.
The relevant installation guidelines must be observed when arranging the wiring.
The device lines must be free of tensile stress and must be provided with a kink protection if the enCore FC is being installed in a swivel frame.
Enough length must be allocated to cables so no tensile stress occurs in cables when the swivel frame is opened up.
It is recommended that the lines be placed on transfer terminals in a switch cabinet, and then be connected with the enCore FC from that point. However, these terminals must sometimes fulfill Ex regulations, and must also be sealable if applicable, for example in order to fulfill the requirements of an applicable approval.

7 Device Configuration and Commissioning

All newly delivered devices are factory-configured so as to support all available interfaces.
Setting enCore device parameters, i.e. configuring device functions and adapting the device to the actual measuring point, is done on site using the enSuite software.
enSuite system requirements and installation
System requirements and details about how to install enSuite are available in a separate installation guide. The currently valid version of the file is always located on the enSuite installation CD. Alternatively you can download the PDF from the Elster Instromet website from the section Software downloads:
www.elster-instromet.com/en/software-downloads
A gas specialist must be consulted for this procedure. The presence of a metrology expert is also required when the device is being used within the scope of legal metrology.
The online help function in enSuite software contains instruc- tions for operating enSuite as well as a detailed description of its parameters.

7.1 Device Configuration

This section gives brief instructions on how to create a complete confi- guration for enCore devices and how to transfer the configuration into the device on-site via USB. For details refer to volume Configuration of Device Software” of the enCore FC manual.
Opening the security switch
As a general rule, there are parameters which cannot be changed, if the security switch is closed especially if the device is used within the scope of legal metrology. If a new parameterization refers to such a parameter, then the security switch must be opened, such that the presence of a metrology expert may be required in some instances.
The following steps are required:
Start enSuite on your computer. Establish the USB connection with your enCore device. Use enSuite to create a suitable device parameterization. Open the security switch if required. Transfer the parameterization to the device.
As soon as the transfer of the parameterization begins, a login dialog
appears on the computer screen.
Login as an administrator.
Standard login
A standard login as an administrator (user name admin1 and an
empty password) typically works here if you have not changed the start-up settings for user administration. Otherwise follow the individual user configuration of the device.
After a successful login the data transfer begins.

Operating Instructions
enCore FC
In very rare cases, it may happen that the device shows a prohibitive sign in the home display after parameterization and restart, e.g.:
Fig. 7-1: Emergency mode
The prohibitive sign indicates that the device has started in emergency mode due to a system error that has been detected during re-start. In this case only basic functionalities for error handling are active; all the other functions are disabled.
Typically, this error is caused by an erroneous parameterization configuration and can be solved by transferring a correct para- meterization to the device.
Please contact us if you require further assistance for diagnosing the error.

7.2 Commissioning the Measurement System

The presence of a metrology expert is required for final commis- sioning of the device when it is used within the scope of legal metrology. In this case, the conditions of the applicable authori- zation must be observed as well.

7.2.1 Checking Device Settings

The legally relevant parameters can be checked in special device displays ( volume “Use in Legal Metrology of the enCore FC manual). The enSuite software will allow you to carry out a complete check of the current device parametrization when the software has an online connection to the device.

7.2.2 Checking Measurement Input Values

Input measurements, in particular input values for flow conversion (measurement data from gas meters, pressure transmitters, temperature transmitters and, if applicable, gas composition measurement devices) can be checked on the device display ( volume “Use in Legal Metrology of the enCore FC manual).

7.2.3 Checking Output Signals

Parameterized output signals can be measured using appropriate measure- ment devices and checked in that way.

7.2.4 Checking Digital Communication (Modbus, etc.)

Appropriate tools (e.g. a protocol analyzer) can be used to check digital communication.

7.2.5 Checking Measurements and Calculations

A final check of the accuracy of measurement results and calculations must be executed when the device is used within the scope of legal metrology. A metrology expert is required for this process, and the applicable legal regu- lations must be observed.

7.2.6 End of Commissioning (from Basic System 03-24)

enSuite provides a convenient function to prepare an enCore flow computer for operation at the end of commissioning. This function combines different actions (e.g. the action Erase fiscal audit trail or Set counters) per stream.

enCore FC
This function is available in normal mode during online parametrization only. Requirement is that the calibration switch is open. Depending on the action you want to execute, you need the user right Erase fiscal audit trail/fiscal archives and/or the rights for the individual counters on parameter level.
Call:
<Stream 1/Stream 2>, tab End of commissioning

7.2.7 Sealing (if necessary)

It may be necessary for the device as well as sensor and signal lines to be sealed by a metrology expert when it is used within the scope of legal metro- logy. The conditions of the applicable authorization must be observed in this case.
