4 Assembly and Installation
The FC1 is provided for assembly within a 19" cabinet, and is available in
either a mounting width of 1/3 or a mounting width of 1/2 model. Compliance
with the device's installation depth of 170 mm (with plugs approx. 220 mm) is
necessary so the connection terminals located on the rear of the device
remain accessible.
The FC1 must be installed in an Ex-free installation area (electrical
operating area) outside of ex-zones 0, 1 and 2, in accordance with
protection class IP 20.
It is recommended that the FC1 be installed in a swivel frame.
4.1 Line Connection
WARNING!
Risk of explosion
A risk of explosion exists when connecting any lines to the
ExMFE5 board while the FC1 is powered on!
- Only connect transmitter, pulse generator or signal lines
to the ExMFE5 board when the power supply of the FC1
is disconnected completely.
4 Assembly and Installation
Page 30 of 78 Operating Instructions enCore FC1
ATTENTION!
Risk of short circuit
The FC1 device may be damaged when connecting any lines
while the FC1 is powered on.
- Always make sure the power supply of the FC1 is
disconnected completely before making any change to
device wiring or before connecting transmitter, pulse
generator, signal or data lines.
The transmitter, pulse generator, signal and data lines are connected to the
FC1 by using plug-in screw terminals, each of which is located in a cable
terminal box. 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, make sure 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 straight line-gap of 50 mm
required in the relevant guidelines can be maintained.
The relevant installation guidelines must be observed when arranging the
wiring.
The lines must be free of tensile stress and must be provided with a kink
protection if the FC1 is mounted in a swivel frame.
Dimension the cable length in such a way that there is no tensile stress on
the cables when the swivel frame is opened up.
It is recommended that all incoming lines be placed on transfer terminals in a
switch cabinet, and then be connected with the FC1 from that point.
However, these terminals have to comply in part with the Ex-regulations, and
must possibly also be sealable, for example in order to fulfill the
requirements of an applicable approval.

5.2 Device Parameterization
This section gives brief instructions on how to create a complete
parameterization for enCore devices and how to transfer it into the device
on-site via USB. Please refer to FC1 Manual Part 3a for details on this
process.
The following steps are required:
1. Start enSuite on your computer.
2. Create the USB connection to your enCore device.
3. Use enSuite to create an appropriate parameterization for the device.
4. Transfer the parameterization into the device.
As soon as the transfer of the parameterization starts, a user login
dialog appears on your computer screen. If the initial settings for the
user administration have not been changed, the default administrator
login (user name admin1 and empty password) will work. Otherwise,
you have to regard the individual user configuration of the device.
There are probably parameters that are not allowed to be changed
when the security switch is closed - especially if the device is within the
scope of legal metrology. If a new parameterization affects such
parameters, it is therefore necessary to open the security switch, so that
the presence of an authorized metrology expert may be required.
Device Configuration and Commissioning 5
enCore FC1 Operating Instructions Page 63 of 78
In very rare cases after parameterization and restart, it may happen
that the device shows a ‘No entry’ sign in the home display (see
figure below).
Figure 5-11
The ‘No entry’ sign indicates that the device has started in emergency
mode because of a system error that has been detected during
restart. All functions apart from basic functions for error handling are
deactivated. Typically, this error results from a wrong configuration
and can be solved by transferring a correct parameterization. Please
contact Elster if any further assistance or error diagnosis is required.
5.3 Commissioning the Measurement System
Note: The presence of a metrology expert is required for final commissioning
of the device when it is used within the scope of legal metrology. In this
case, the conditions of the applicable approval must be observed as well.
5.3.1 Checking Device Settings
The legally relevant parameters can be checked in special device displays
(cf. Part 1 of the FC1 Manual). The enSuite software will allow you to carry
out a complete check of the current device parameterization when the
software has an online connection with the device.
5.3.2 Checking Measurement Input Values
Measurement input values, in particular input values for flow computing
(measurement data from gas meters, pressure transmitters, temperature
5 Device Configuration and Commissioning
Page 64 of 78 Operating Instructions enCore FC1
transmitters and, if applicable, gas quality measurement devices) can be
checked on the device display (please refer to part 1 of the Manual).
5.3.3 Checking Output Signals
Parameterized output signals can be measured using appropriate measuring
instruments and checked in that way.
5.3.4 Checking Digital Communication (Modbus, etc.)
Appropriate tools (e.g. a protocol analyzer) can be used to check digital
communication.
5.3.5 Checking Measurements and Calculations
A final check of the accuracy of measurement results and calculations must
be carried out if the device is used within the scope of legal metrology. A
metrology expert is required for this process, and the applicable legal
regulations must be observed.
5.3.6 Sealing (if necessary)
It may be necessary for the device as well as for transmitter, pulse generator
and data lines to be sealed by a metrology expert when it is used within the
scope of legal metrology. The requirements of the applicable approval must
be observed in this case.
Maintenance 6
enCore FC1 Operating Instructions Page 65 of 78
6 Maintenance
The FC1 is practically maintenance-free. Only the battery, which is required
for purposes of data retention when the power supply is switched off, must
be replaced at certain intervals.
This section contains instructions for replacing the battery and cleaning the
device, as well as contact data for customer service and the service hotline.
6.1 Battery Replacement
The FC1 battery mainly comes into use when the FC1 is switched off
permanently, or it is being switched off then switched back on at frequent
intervals. The battery consumption can be neglected while the device is
powered on.
In addition, the battery loses energy as it ages.
The battery must be replaced with a new one at least every 10 years.
Special case: When the device is being stored and therefore permanently
disconnected from power supply, the battery loses approx. 3% of its charge
every month. The battery is therefore completely discharged after 3 years. It
is therefore recommended that the battery be replaced by a new one when
the FC1 has been without power supply for longer than 1 year.
Special case: The battery also loses additional charge when the power
supply is frequently disconnected and reconnected during operation. It is
therefore recommended that the battery be replaced by a new one when the
power supply has been disconnected and reconnected for 1,000 times.
The FC1 automatically signals as soon as battery capacity has dropped to
20% of that of a new battery.
A dead battery may sometimes lead to a loss of the measurement
data that was calculated and saved.

7.1 Storage
ATTENTION!
Material damage from formation of condensation!
Storing the device can lead to the formation of condensation
resulting from variations in temperature. This may result in the
device malfunctioning at a later time.
- After the device was stored or transported in cold weather
or if it was subject to extreme variations in temperature, it
must be slowly brought to room temperature before it is
commissioned.
- The device must undergo a waiting period of at least 12
hours before it is put into operation if condensation formed
during storage.
The device's time may no longer be exactly correct after it is stored
for longer periods; i.e. its clock must be checked and set if
necessary.
It is also possible counters and archive files may have been
deleted.
Counters and archive files as well as time and date settings are
deleted if the device's power supply was interrupted during storage
because the battery was disconnected.
The battery (operational life of 3 years) must be replaced in case of
longer device storage times (cf. section 6.1).
