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.

• 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).

For a description of the process boards refer to chapter 5.5
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.

risks that arise from the specific working conditions when the
enCore FC is being used. The operator must include these items in
the form of Operating Instructions for the enCore FC.
• The operator must review, over the entire operational life of the
enCore FC, whether the Operating Instructions prepared by him or
her correspond to the current status of the bodies of regulations,
and adapt the instructions if necessary.
• The operator must definitively regulate and establish the respon-
sibilities for enCore FC assembly, connection, commissioning,
operation and maintenance.
• The operator must ensure that all employees who work with the
enCore FC have read and understood these Operating Instructions.
In addition, the operator must train these personnel at regular
intervals and inform them of the risks involved with the device.
• The operator of the overall system in which the enCore FC is
integrated must provide the personnel with the required protective
equipment.
In addition, the operator is responsible for ensuring the enCore FC is always
in a technically perfect state. The following therefore apply:
• The operator must ensure that the installation and maintenance
work described in these Operating Instructions are performed
properly.
• The operator must have all safety installations checked regularly to
ensure they function correctly and are complete.

5 Design and Function
5.1 Functional Description of enCore FC devices
The specific function of an enCore device depends on its device type
( chapter 4.2 Intended Use, p. 25):
• enCore FC1
The FC1 is a process computer, which is mainly used as a flow
computer for natural gas, thus to measure and calculate the gas
flow.
• enCore MC1
The MC1 is a monitoring and controlling unit, mainly for use in
industrial gas measurement.
For these special tasks, various measuring devices are connected to the
device (depending on the application, e.g. gas meter, pressure transmitter,
temperature transmitter and gas quality measurement device).
The enCore FC provides various interface options for the various types of
measurement device types:
Device Type Connection Option
gas meter • pulse interface for turbine, rotary piston or
other pulse-generating gas meters
• serial interface for ultrasonic gas meters via
a manufacturer-specific digital protocol

5.2 Device Description
The enCore FC is housed in a 19“ housing with 1/3 overall width (max. 4
process boards) or 1/2 overall width (max. 7 process boards).
screen as well as the 2 function keys and 5 navigation keys for operation are
located on the front panel. In addition, the USB connection, security switch
and 2 status LEDs are located on the front panel.
At the rear side of the device, the CPU board provides a LAN interface and
two RS232/RS422/RS485 serial interfaces. Devices with protocol interfaces
can be connected to these interfaces, e.g. gas quality measuring devices.
Various other I/O boards can be mounted from the rear side of the device.
The maximum number of boards depends upon the housing design. A
maximum of four process boards can be installed in a device with 1/3 overall
width, while a maximum of seven can be installed in a device with 1/2 overall
