1.10 Storage
CAUTION!
Reduced performance after exceeding or falling below the valid temperature range of the batteries.
Exceeding or falling below the valid temperature range can reduce the performance of the batteries when storing the device.
Therefore:
– For longer-term storage, ensure that the valid temperature range of the builtin batteries between -40 °C and +60 °C is not exceeded or fallen below.
CAUTION!
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.
Therefore:
– After the device has been stored or transported in cold weather or if it has been subject to extreme variations in temperature, bring it slowly 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.
If the power supply of the device is interrupted during storage from clamping the batteries, the time and date need to be reset.
The following regulations apply for storage:

• Relative humidity may not exceed 93%.
• Do not store the packaging units outdoors.
• The storage temperature may not fall below -40°C and exceed +60°C.
• Avoid mechanical vibrations during storage.

Security considerations for your network

EK series volume converters are used in modern billing infrastructures and network control systems to supply process information such as meter readings, measurements and messages to a billing or control centre. A connection of this type constitutes a significant security risk which must be given careful consideration when designing the network.
2.1 How to report a vulnerability
A vulnerability is defined as an error or weakness in the software which can be exploited to adversely affect or reduce the operation or security of the parameterization or device software.
Honeywell reviews all reports about vulnerabilities relating to Honeywell products and services.
You can find further information about the Honeywell Security Policy at: www.honeywell.com/product-security
If you would like to report a possible vulnerability in a Honeywell product, follow the instructions on the Honeywell website at: www.honeywell.com /product-security
You can find information about current malware threats at: www.honeywellprocess.com/en-US/support/Pages/security- updates.aspx
Or
Contact your local Honeywell Process Solutions Customer Contact Centre (CCC) or our Elster Gas Technical Support team (see section 1.4.1 “Customer services and repairs”, page 11).
2.2 Implementing stringent password guidelines
Since various types of attacks on passwords take place these days, you should follow best practices for password management. Here are a few time-tested methods:

• Change standard passwords
• Use secure passwords. A secure password for LIS devices consists of eight characters.
• Change passwords on a regular basis.
• Change passwords immediately in case someone has tried to attack the system.
• LIS200 uses role-based authentication, please follow best practices for shared passwords like secured distribution and secured storage.

Passwords can be changed via so-called insecure protocols without reauthentication!
Note that when a password is changed via IEC 62056-21 and DLMS, the initial password is not queried again. This vulnerability enables a potential attacker to assign a new password without specifying the old password!
It is therefore even more important to protect data communication from third- party access.
Document any changes from time-tested methods.
If your system does not allow one of these time-tested methods to be used, you should document this. For example, if special symbols such as the equals sign “=” are not allowed in passwords.
2.3 Preventing unauthorized external access using a firewall
To reduce the risk for your network, we recommend that you use a firewall or another mechanism to restrict network traffic between the “external” central billing or control system and the “internal” network of the gas metering systems. Furthermore, EK devices should only be installed in the gas metering system, where access control is guaranteed, i.e., protective action is taken to prevent unauthorized persons gaining access to the device.
We also recommend that you only allow protocols and ports which are actually used for data exchange with the external network and that these are added, for example, to the firewall’s whitelist.
Refer to the information in section 2.4 Data security for data at rest and in transit. Fig. 1: Router and firewall between the metering systems and control centre – example with indication of security zones L0..L3 and higher according to IEC 62443
We recommend opening safety zone L0 only for zone L1 and not for zones L2, L3 and L4.
2.4 Data security for data at rest and in transit
2.4.1 Data security for data at rest
Data at rest are the data which are temporarily or permanently stored in the EK205-M. These data are unencrypted in the EK series. This means it is even more important to protect the device from unauthorized access.
See section 2.3 “Preventing unauthorized external access using a firewall”.
2.4.2 Data security for data in transit
Data in transit are data which are currently being transferred between the EK205-M and, for example, a control station in a public or trustworthy network.
The protocols used with the EK205-M normally transfer the data in plain text form. If possible, you should therefore use the secure version of a protocol (see section 4.9 “Supported protocols”, page 28).
See section 2.3 “Preventing unauthorized external access using a firewall”.
Using an encrypted VPN connection
We recommend that you use a VPN connection whenever you require a secure data connection, but a secure protocol is not supported for the data transfer.
In a VPN, the data are transferred between two or more subscribers in encrypted form. Therefore, a VPN connection is extremely important, for example for mobile access to a volume conversion device, for accessing a private network or for data communication using different systems.

5.3 Brief description
The volume converter EK205-M is an explosion-protected, electronic device that calculates from a volume of a gas determined by an external meter in operating mode the volume in normal mode and therefore the energy share of the relevant gas volume.
In addition, using the registration function, the reporting inputs / outputs, the serial and optical data interfaces of the device, the gas load of a line can be monitored, registered and passed on.
The recording of the status parameters required for this is carried out via an internally connected pressure sensor and a temperature sensor. When using the EK205-M as a Temperature Conversion Device, the momentary values of temperature are measured, and the pressure is set as a constant. As an operating element of the EK205-M, an alphanumerical display and a keyboard on the front side of the device are available.
5.4 Connections
The Volume Conversion Device EK205-M has connection options for:

• Two batteries
• External supply for the basic device

To monitor and register the calculated data and to pass on the data and program its functions, the following are available:

• 2 meter and reporting inputs DE1, DE2
• 2 pulse and reporting outputs DA1, DA2
• Serial data interface
• Optical data interface

– For EK205-M powered with external power supply for the basic device, the external supply must be switched off before opening the housing.
Danger of death!
For EK205-M powered with external power supply for the basic device, the external power supply voltage must be switched off before opening the housing, ensure it is not turned back on and verify that there is no voltage.
– Remove the four screws from the top of the EK205-M and open it. (see Fig. 22) – Disconnect the modem and basic device battery if already connected. (see Fig. 23 and Fig. 24) – Push the metal bracket in the SIM card slot back halfway (towards right in Fig. 24), and flip open the cover (see Fig. 25).
Only SIM card slot A should be used while using the EK205-M. SIM card slot B usage is not recommended.– Insert the SIM card from the rear into the card slot (in the lid), so that the gold contacts face downwards in the closed end and the bevelled side is at the open end of the lid (see Fig. 26).
– Click the lid shut again and gently slide the metal bracket outwards towards left to close the lock.
– Re-connect the modem and basic device battery.
Before using the EK205-M for the first time, connect the battery to the modem. It has not been connected at the factory in order to avoid an unnecessary load on the battery!
– For EK205-M powered with external supply for basic device, switch-on the external power supply after re-connecting the modem battery supply.
– Close the housing cover and retighten the screws.
Caution
The “ECM-2G-UG350” (GSM / GPRS)” modem is supplied with a battery, after connecting the modem to the battery, the modem must be quickly commissioned as described in ⇒ section 8.1.4 or 8.1.6 in order to avoid an unnecessary load on the modem battery! (Up until the first opening of a time window approx. 1 … 5 mA, flow after the closing the first time window. After all the other time windows only 0.03 … 0.09 mA flows!)
8.1.3 Unlocking the SIM card
a) If necessary, the SIM card must be unlocked, the PIN must be entered.
If the inserted SIM card’s PIN (“Personal Identification Number”) is activated, carry out the following instructions to unlock it: − Move the cursor to the “Serv.” tab in the EK205-M’s display, then to
Interfaces > internal modem > GSM and GPRS > PIN.
− Press the ENTER key and enter the first PIN digit using the and arrow keys.
The PIN must be entered right aligned in the EK205-M!
− Move the cursor through the next digits using the key and enter them.
− After entering the last digit press the ENTER key, to save the input.
− Under “P.Sta” the “Pin New” is now ready for confirmation.
If “P.Sta” is not displayed, move the cursor down using the arrow keys.
− As soon as a communications time window is opened via the modem, the new PIN is used. After a few seconds, under “P.Sta” the message “PIN OK” is displayed if the correct PIN was entered, or the message “PIN Error” if the PIN was incorrectly entered.
Further commissioning steps are necessary, before the power for the basic device is switched on again on an EK205-M with external power for the basic device.
8.1.4 GSM Operation
The 2G modem is already prepared for transmission via GPRS when delivered. If GSM operation (CSD) is explicitly desired, the modem must first be set to CSD mode according to the following section. Please note that CSD mode is no longer guaranteed by the provider.
8.1.4.1 Parameterization
For parameterization of the EK205-M, you need a connection cable for the optical interface as well as the enSuite program. enSuite can be downloaded free of charge from the Honeywell website in the “Software Downloads” section: www.elster-instromet.com/en/software-downloads
a) Close time window / pre-allocate connections
To ensure that parameterization functions correctly, the time windows 1 to 4 need to be closed, and parameterization of the connections must be pre- allocated. To do this:
− Connect a PC or laptop with enSuite installed to the EK205-M optical interface using the connection cable.
− Start enSuite and set up the communication link to the EK205-M using the optical interface. (⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
− Send the following files to the EK205-M (⇒ section 7.6 Send parameter file, p. 51):EK205 -M Reset all types of connections and time windows to factory setting ()11
− Then wait a minute, for any communications activity in progress on the EK205-M to be safely stopped.
b) Sending parameter file
− Send one the following file to the EK205-M (⇒ section 7.6 Send parameter file, p. 51): ECM-2G-UG350: EK205_1v07.. – int. GPRS-Modem (uBlox)_a.WPP mode only ()11
Caution: Even if a GPRS modem is only to be put into operation for GPRS data transmission in the GSM network, there is a risk that unconscious costs will be incurred if no APN is entered in the EK205-M AND if an APN is stored on the SIM. In this case, the modem uses the APN from the SIM and, as a result, every time a GPRS session is set up (at each time window start), a minimum data volume (e.g. 10 or 100 kB) will be available depending on the provider and the tariff invoice! You can avoid this by using one of the parameter files listed here.
− For the following customized settings and tests required, press “Navigation” on the left-hand side and then “Parameterize online” at the bottom of the navigation window.
All the values listed in enSuite under “Parameters” can be found on the “Serv.” display tab of the EK205-M under the same path.
c) Setting time window for potential data retrievals
In the base configuration now displayed you can define cyclic time windows, during which data can be retrieved from the EK205-M via the modem. There are two available time windows, which operate on EK205-M basic device battery power only and for versions of the EK205-M with external power supply for the basic device there are two more, which operate only on mains voltage.
Make the battery power time windows only as long and frequent as absolutely necessary. Each time window reduces the EK205-M’s battery life.
The editable time windows are not directly accounted for in calculation of expected battery life of the “Bat.R” EK205-M batteries. Therefore, the expected battery life is not updated when the time windows are changed. Past time windows and data transfers are however used in remaining battery and service life calculation for the “BatRC”.
− The two battery-power time windows for the basic device are set in the enSuite device window under:
11 The “x” stands for the version of software on the device, e.g. “2v2”.
The asterisk * stands for a small letter which indicates the version of the file, e.g. “a”.
– Parameters > Interfaces> Connections > Connection 1 and
– Parameters > Interfaces> Connections > Connection 2
− The two external power for the basic device voltage time windows are set under:
– Parameters > Interfaces> Connections > Connection 3 and
– Parameters > Interfaces> Connections > Connection 4
If you do not need a time window, you can deactivate it by setting the time window start and end to the same value.
− Press the “Transfer changes to device” icon at the top of the enSuite window.

8.1.4.2 Checking GSM field strength
Before starting a data transfer via the modem, you must ensure that there is adequate reception field strength.
Danger of death!
Ensure that before you switch the external supply for the basic device, the housing on the EK205-M is securely closed.
− For an EK205-M with external supply for the basic device, reconnect the external supply now.
a) Opening the test time window on the device
The test time window only needs to be open if none of the time windows 1 to 4 are open.
The use of a test time window is only possible if an appropriate battery for the modem is available.
− Move the cursor to the “Serv.” tab in the EK205-M’s display, then to Interfaces> internal modem > CWTst
− Press the ENTER key in order to enter the length of the test time window in minutes  ⇒ “0” flashes.
− Move the cursor with the arrow keys or **to the digits and change these with the arrow keys or  to 10, for example.
− After the desired digits have been changed, press the ENTER key in order to confirm the input.
It is possible to abort the entry by pressing the ESC key.
Only enable the test time window for battery operation for as long as is required. Each time the test time window is open, this reduces the life of the EK205-M battery.
The editable time window is not directly reflected in the forecast of the remaining battery life of the batteries” BatR” of the EK205-M. Therefore, the forecast battery life is not changed if the time window is changed. Past time windows and data transfers are however used in the remaining battery capacity “BatRK” and remaining service life forecast calculation.
b) Display GSM field strength
− Check whether corresponding bars indicating the reception level for the internal modem (“i”) appear on the main EK205-M display.
− Move the cursor to the “Serv.” tab in the EK205-M’s display, then to Interfaces > internal modem > GSM and GPRS > GSM.L
− The percentage field strength is now displayed under GSM.L.
− In order to update the level display, move the cursor to GSM.L, please press the ENTER key of the EK205-M and then wait approx. 30 seconds. This makes it possible to determine the best installation position for an external GSM antenna.
With a field strength below 50% data transfer issues may be encountered. You can remedy this in the majority of cases with the external antenna, mounted somewhere suitable.
8.1.4.3 Retrieving data with enSuite
a) Opening the test time window for the following test retrievals with enSuite
The test time window only needs to be open if none of the time windows 1 to 4 are  open.
− If the communication link to the EK205-M via the optical interface is not set up, it must be created.
(⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
− Select “Navigation” on the left-hand side of the enSuite window and then “Parameterize online” at the bottom of the navigation window.
− In the top of the device window open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs, and then select “internal modem” (not the plus sign before).
− Click on the “0” value next to “Test call acceptance window” in the right- hand side of the window and enter a duration in minutes (i.e. 10), for the test time window for the test retrieval to remain open. For a battery-operated EK205-M please do not enter an excessively long duration, as this will adversely affect the battery life.
− Press the “Transfer changes to device” icon at the top of the enSuite window.
The EK205-M is now available via the modem for the duration set.
− In enSuite press the “Disconnect” icon or “Disconnect from all devices” to terminate the optical interface communication link between enSuite and the EK205-M.
b) Test retrieval via the modem
− Set up the modem communication link (=GPRS12 connection) between enSuite and EK205-M.
(⇒ section 7.2 Setting up the communication link to EK205-M via a modem, p. 5050)
− Once the communication link is set up, you can carry out checks, for instance view certain parameters. To do this press “Navigation” on the left- hand side of the enSuite window and then “Parameterize online” in the bottom of the navigation window, then click on the plus sign next to “Parameters” and then its subsections.
− In enSuite press the “Disconnect” symbol or “Disconnect from all devices” to end the test retrieval.
8.1.5 National Roaming – Preferred Network Operator
If the SIM card used supports “National Roaming”, the modem usually first tries to connect to its own mobile network. If there is no coverage (i.e. sufficient reception field strength) at the measuring point, the modem books itself into a “foreign” mobile network, which is permitted by the “National Roaming” option of the SIM card.
For information on which “foreign” mobile networks are supported for National Roaming, please contact your mobile network operator / provider. Only he can tell you bindingly which foreign networks he allows via “National Roaming”.
If “National Roaming” is not to be used automatically, but a specific network operator is preferred, the preferred network operator must first be entered and then the “Network provider selection” mode must be specified.
8.1.5.1 Input „Preferred Network Operator“
To enter or change the information for the preferred network operator, navigate in the enSuite under “Parameterize online” > “Parameters” > “Interfaces” > „Internal Modem“ > „GSM & GPRS“ to the entry Name of the preferred operator “Oper.”.
The entry itself can be made either by the plain text name of the network (e.g. “t-online.de”) or by its “Mobile Country & Network Code” (e.g. “26201”). If this parameter is deleted, the network provider selection mode is selected automatically, regardless of whether another mode is selected.
The entry in plain text must exactly match the provider’s name specified on the SIM card. For example, “T-Mobile” is not identical to “telekom” or “T-D1”. We therefore recommend that you enter the unique Mobile Country & Network code.
Lists of the possible “Mobile Country & Network Code” can be found on the Internet at https://www.mcc-mnc.com/, for example. However, the specifications of your mobile phone provider whose SIM cards you are using are binding.
8.1.5.2 Mode „Network Provider Selection“**
To change the parameter for the “Network provider selection” mode, navigate in the enSuite under “Online parameter settings “Parameterize online” > “Parameters” > “Interfaces” > “Internal Modem” > “GSM & GPRS” to the entry “Mode for logging in with an operator” “MdLog”.
Now select one of the three possible modes. The meaning and function are described in the following table.

modem. Which network is selected depends on the local reception conditions and the tariff properties of the SIM card inserted by the respective provider. A value parameterized under “Preferred network provider” is not taken into account during selection.
1: manually| The network parameterized under “Preferred network provider” is specified here. If it is not possible to log on to this network with the SIM card inserted, the modem is switched off and an error message is displayed in the connection status.
4: man. first| The modem tries to log in to the network specified under “Preferred network provider”. If this is not possible, however, the modem is not switched off, but a new logon attempt is started, in which the network selection is left to the modem (analogous to mode 0: auto). If this logon attempt is also unsuccessful, the modem is switched off and a corresponding error message is displayed in the connection status.

The mode “1: manual” should only be selected if it is certain that

1. the ‘preferred network operator’ is also authorized by the mobile operator which provided the SIM cards with the ‘national roaming’ option and
2. there is also sufficient coverage (i.e. receiving field strength) at the measuring point for the preferred network.

For these reasons, this mode can only be selected via the optical interface and keyboard and should only be selected after the volume corrector has been installed on site. After selecting this mode, it is strongly recommended to open a (test) time window to check whether the modem was able to log into the parameterized network.
8.1.6 TCPserv operation (GPRS)
In this modem operating mode, you can access the EK205-M via the network (TCP/IP), to which
your retrieval system is connected, i.e., you do not require an additional retrieval system modem. Data transfer is normally faster than with GSM operation, (as explained in ⇒ section 8.1.4) Here the GPRS Modem in the EK205-M functions as a TCP-Server and may be addressed by a TCP client that is listed in its readout software through a static IP address. To allocate a static IP to the modem during the setup of the GPRS session, they must (together with their network provider) maintain a virtual private network (VPN) which must be enabled on the SIM used in the modem.
8.1.6.1 Parameterization
For parameterization of the EK205-M you need a connection cable for the optical interface as well as the enSuite program. enSuite can be downloaded free of charge from the Honeywell website in the “Software Downloads” section:
www.elster-instromet.com/en/software-downloads

a) Closing the time windows
In order that the parameterization works correctly the time windows 1 to 4 must be closed. To do this:
Connect a PC or laptop with enSuite installed to the EK205-M optical interface using the connection cable.
Start enSuite and set up the communication link to the EK205-M over the optical interface.
(⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
Select “Navigation” on the left-hand side and then “Parameterize online” at the bottom of the navigation window.
In the top of the device window open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs, and then select “Call time windows”.
In call windows 1 to 4 set start and end to the same value for each one and then select the “Transfer changes to device” icon at the top of the enSuite window.
Then wait a minute, for any communications activity in progress on the EK205-M to be safely stopped.
b) Sending parameter file
Send the following parameter file to the EK205-M (⇒ section 7.6 Send parameter file, p. 51): ECM-2G-UG350: EK205_1v07.. – int. ECM-2G-UG350 TCPServ.wpp
For the following customized settings and tests required, press “Navigation” on the left-hand side and then “Parameterize online” at the bottom of the navigation window.
All the values listed in enSuite under “Parameters” can be found on the “Serv.” display tab of the EK205-M under the same path. However, it is not possible to enter the following APN data via keyboard but must be entered via the enSuite parameterization software.
c) Configure individual parameters
In the top of the device window open the path “Parameters” > “Interfaces” > ” Terminal Interfaces” by clicking on the relevant plus signs, and then select “GSM and GPRS”.
On the right-hand side of the window you will now see several values, in which the following must be entered:

VPN (Virtual Private Network) in use. The values to be entered can normally be obtained from your IT department or SIM card provider.
APN user name “UName”
APN password “PwAPN”| Port means the TCP port no. of the retrieval system in use.
IP port “Port”| 0 = None
1 = CHAP (default)
2 = PAP| Depending on the provider, the protocols specified on the left can be used to log on to the GPRS network. Consultation with the provider may be required.

If you fail to input an Access Point Name (APN), the APN that is saved on the SIM is used. Since this is usually a public APN (no access to a VPN) and since a dynamic IP address is allocated when a GPRS session with a public APN is set up, the TCP server function cannot be used! This is because a static IP address would be needed for this purpose. In such a case, the modem could only be used as TCP client.
Caution!
Without the input of an APN there is the risk that unspecified costs may be incurred, as with every set up through a GPRS provider and based on a corresponding tariff a minimum data volume (e.g., 10 or 100 kB) will be billed!
Press the “Transfer changes to device” icon at the top of the enSuite window.
If required (i.e. with the aid of the enSuite user list) two further addresses for a “Domain Name System” can be entered in addresses 3:0794.0 and 3:0795.0. This is however not essential.
d) Setting time window for potential data retrievals
In the base configuration now displayed you can define time windows, during which data can be retrieved cyclically from the EK205-M via the modem. There are two available time windows. One which operate on EK205-M basic device battery power only and the other for versions of the EK205-M with external power supply for basic device.
Make the battery power time windows only as long and frequent as absolutely necessary. Each time window reduces the EK205-M’s battery life.
The editable time windows are not directly accounted for in calculation of expected battery life of the “Bat.R” EK205-M batteries. Therefore, the expected battery life is not updated, when the time windows are changed. Past time windows and data transfers are however used in remaining battery and service life calculation for the “BatRC”.
The two battery-power time windows for the basic device are set in the enSuite device window under:
– Parameters > Interfaces> Connections > Connection 1 and
– Parameters > Interfaces> Connections > Connection 2
The two external supply for the basic device time windows are set under:
– Parameters > Interfaces> Connections > Connection 3 and
– Parameters > Interfaces> Connections > Connection 4
If you do not need a time window, you can deactivate it by setting the time window start and end to the same value.
Press the “Transfer changes to device” icon at the top of the enSuite window.
8.1.6.2 Checking GSM field strength
⇒ See section 8.1.4.2 Checking GSM field strength (p. 58)
8.1.6.3 Retrieving data with enSuite
a) Opening the test time window for the following test retrievals with TCP/IP
The test time window only needs to be open if none of the time windows 1 to 4 are  open.
The use of a test time window is only possible if an appropriate battery supply for the modem is available.
If the communication link to the EK205-M via the optical interface is not set up, it must be created.
(⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
Select “Navigation” on the left-hand side of the enSuite window and then “Parameterize online” at the bottom of the navigation window.
In the top of the device window open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs, and then select “internal modem” (not the plus sign before).
Click on the “0” value next to “Test call acceptance window” in the right-hand side of the window and enter a duration in minutes (i.e. 10), for the test time window for the test retrieval to remain open. For a battery-operated EK205-M please do not enter an excessively long duration, as this will adversely affect the battery life.
Press the “Transfer changes to device” icon at the top of the enSuite window.
The EK205-M is now available via the modem for the duration set.
In enSuite press the “Disconnect” or “Disconnect from all devices” icon to terminate the optical interface communication link between enSuite and the EK205-M.
b) Test call up through the TCP/IP network (incl. GPRS network)
Set up the network communication link between enSuite and the EK205-M.
(v section 7.3 Setting up the communication link to EK205-M via a network (TCP/IP))
Once the communication link is set up, you can carry out checks, for instance view certain parameters. To do this press “Navigation” on the left-hand side of the enSuite window and then
“Parameterize online” in the bottom of the navigation window, then click on the plus sign next to “Parameters” and then its subsections.
In enSuite press the “Disconnect” symbol or “Disconnect from all devices” to end the test retrieval.
8.1.7 Hiding APN access data between two “market partners”
The EK205-M has two independent interfaces that can be used for remote reading. If both interfaces are used with GPRS modems by two different market partners (e.g. network operator and supplier), it is often desired that the users cannot view the APN access data. This prevents misuse of SIM cards if they are stolen.
To use this function, the following parameter files are available, which can be individually transferred to the EK205-M using the enSuite software. The settings refer to the access rights for the “Administrator” and the “Data reader”.
1. Lock APN data – administrator modem at terminals, data reader internal modem
→ The “data reader” party uses the internal interface (2G modem/ethernet card).
2. Lock APN data – administrator internal modem, data reader modem at terminals
→ Administrator access uses the internal interface (2G modem/ethernet card)
If the read and write rights for one party are removed, the return to the factory settings is only possible with the calibration switch open!
To reset the setting, i.e. the parameters can be seen under both access rights, there is an additional file
→ Reset locking of APN data.

Therefore:
Ensure correct positioning of the cable guides when closing.
– Close the housing cover and retighten the screws.Fig. 35: EK205-M with external antenna installed
The external antenna stand base has magnet for installing it on the ferromagnetic surface.
– If available, place the antenna on the ferromagnetic surface for the firm gripping and adjust the antenna position to achieve best possible reception.
To check the function, you may now open a time window for testing and check the GSM signal quality on the EK205-M display (⇒ section 8.1.4.2 Checking GSM field strength, p. 58) and for a test call off with enSuite (⇒ section 8.1.4.3. Retrieving data with enSuite, p. 59).
If using an external address, the position of the antenna should be chosen in such a way that the best possible reception is achieved.
8.1.10 Position of the antenna for gas meter mounting with Encoder
If the EK205-M is mounted on a gas meter with encoder, the antenna must not be placed near the bottom side of the housing, else the encoder function could be disturbed during modem operation as the antenna on the bottom of the housing is too close to the encoder.
8.2 Devices on the serial interface
Modem and RS232/RS485 serial communications are mutually exclusive. When modem is connected, RS232/RS485 communication interface cannot be used.
8.2.1 Direct connection of the RS232 interface (e.g. COM port on a PC)
In battery operation, the battery service life can be significantly reduced by this application. Therefore, set the data call acceptance window for battery operation to the smallest possible value. (see chapter 8.2.1.2)
8.2.1.1 Connection Connect the RS-232 interface in safe assembly area only. Modem power needs to be unplugged and removed from the enclosure to access the RS-232 interface in the field.
8.2.1.2 EK205-M parameterization
To parameterize the EK205-M, you will require a connection cable for the optical interface as well as the enSuite program, which can be downloaded free of charge from www.elster- instromet.com.
a) Closing the time windows
Time windows 3 and 4 must be closed for parameterization to function securely. To do this:

• Connect a PC or laptop with enSuite installed to the EK205-M optical interface using the connection cable.
• Start enSuite and establish the communication link to the EK205-M (⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
• Select “Navigation” on the left-hand side and then “Parameterize online” at the bottom of the navigation window.
• At the top of the device window, open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs, and then select “Call time windows”.
• In call acceptance windows 3 and 4, set start and end to the same value for each one and send the changes using the “Transfer changes to device” icon.
• Then wait a minute for any communications activity in progress on the EK205-M to be safely stopped.

b) Sending the parameter file
• Send the following parameter file to the EK205-M (section⇒
7.6 Send parameter file, p. 51):
EK205_1v0. – RS232 (without Modem)
On the right, you can see the navigation path to this parameter file in enSuite for software versions 1.0x of the EK205-M.For any further customized settings and tests, click on “Navigation” on the left-hand side and then on “Parameterize online” at the bottom of the navigation window. All the values listed in enSuite under “Parameters” can be found in the “Serv.” and “Admin” display tabs of the EK205-M using the same path.
c) Setting time windows for future data retrievals
In the basic configuration now set up, you can define time windows during which data can be retrieved cyclically from the EK205-M via the modem. Time windows 1 and 3 are used here as an example.
You can deactivate time windows which are not needed by setting the start and end of the time window to the same value.
Call acceptance window 1 is closed by default (setting: daily from 00:00 to 00:00).
If you want to transfer data in battery mode, set call acceptance window 1 to the smallest possible time range in order to protect the battery.
If the EK205-M is operating in battery mode and call acceptance window 1 or 2 is permanently switched on, the battery may be empty within a few weeks.

• At the top of the device window, open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs, and then select “Call time windows”.
• Change call acceptance window 1 only if you also want to transfer data in battery mode. Otherwise, the start and the end time should each be at “00:00”, so that the battery is saved.
• In call acceptance window 3, set the start to “00:00” and the end to “23:59”.
• Then click on the “Transfer changes to device” icon at the top of the enSuite window.

8.2.1.3 Retrieving data with enSuite
If the connected device is a PC with enSuite installed, you can now check the data transfer as described here.

• Start the enSuite program on the PC connected to the terminals (e.g.: Start > All Programs > Elster > enSuite).

• Click on the “Search device…” icon (magnifying glass icon).

• Click on the “LIS200” tab in the “Search device and connect” window, which then opens.

• Select
  – “Access” → “LIS200”
  – “User” → “Administrator”
  – “Use default settings”
  – “Connection” →“Serial RS232”
  – “Baud rate”: → “9600”

• Click on “OK”.

• Wait a few seconds until “Connected” is displayed at the bottom of the “Output” window.
  

• Once the communication link has been established, you can view certain parameters to check it. To do this, click on “Navigation” on the left-hand side of the enSuite window and then on “Parameterize online” at the bottom of the navigation window, then click on the plus sign next to “Parameters” and then its sub- items.

• Click on the “Disconnect” or “Disconnect from all devices” icon in enSuite to end the test retrieval.

8.2.2 RS485 interface
8.2.2.1 Connection
These applications only work with an external power supply to the EK205-M, not in battery mode.
If an EK205-M is connected to an RS485 bus, no terminal resistors may be connected to the bus!
Connect the RS-485 interface in safe assembly area only. Modem power needs to be unplugged and removed from the enclosure to access the RS-485 interface in the field.
As a result of its current limit to obtain approval as an intrinsically safe apparatus, the EK205M cannot supply enough current for the terminal resistors. The terminal resistors are not required for the data transfer rates used.
If terminal resistors are essential in your application, connect the devices as described in section 8.2.2.1.2.
For EMC reasons, we recommend that the subscribers are galvanically isolated from each other at the bus. You should therefore give preference to the installation described in section 8.2.2.1.2.
8.2.2.1.1 Two-wire simplex wiring (RS485 mode) 8.2.2.1.2 Two-wire simplex wiring (RS485 mode) with repeater
As specified in section 8.2.2.1, no bus terminal resistors may be connected to the EK205-M. However, these are present in some RS485 connections and in some circumstances cannot be removed. Furthermore, there are often multiple subscribers connected to the bus which means that electrical isolation is recommended.
For these cases, Honeywell recommends the ADAM-4510S repeater from Advantech both for the electrical isolation and for connection to a bus with terminal resistors:

8.2.2.2 EK205-M parameterization
To parameterize the EK205-M, you will require a connection cable for the optical interface as well as the enSuite program, which can be downloaded free of charge from the “Software Downloads” section of the Honeywell website: www.elsterinstromet.com/en/software- downloads
This parameterization applies to both the applications described in sections 8.2.2.1.1 and 8.2.2.1.2.
a) Closing the time windows
Time windows 3 and 4 must be closed for parameterization to function securely. To do this:

• Connect a PC or laptop with enSuite installed to the EK205-M optical interface using the connection cable.
• Start enSuite and establish the communication link to the EK205-M (⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
• Select “Navigation” on the left-hand side and then “Parameterize online” at the bottom of the navigation window.
• At the top of the device window, open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs, and then select “Call time windows”.
• In call acceptance windows 3 and 4, set start and end to the same value for each one and send the changes using the “Transfer changes to device” icon.
• Then wait a minute for any communications activity in progress on the EK205-M to be safely stopped.

b) Sending the parameter file

• Send the following parameter file to the EK205M (section 7.6 Send parameter file, p. 51): EK205_xvx. – RS485-Bus (Without Modem) (*) 1
• For any further customized settings and tests, click on “Navigation” on the left-hand side and then on “Parameterize online” at the bottom of the navigation window.

All the values listed in enSuite under “Parameters” can be found in the “Serv.” display tab of the EK205-M using the same path.
c) Setting the device address
Every bus subscriber requires an individual ID (“device address” or “bus address”) so that the bus master can select precisely one subscriber for data transfer. All other bus subscribers must switch the interface to inactive so as not to interfere with the data transfer.
The device address of the EK205-M depends on which interface protocol you use:
→ Device address for LIS-200 protocol:
The device address for the LIS-200 protocol may be a text with up to 32 characters (no special symbols allowed). It has been set to the default value “1” by the above parameter file.
Proceed as follows to edit the device address of the EK205-M:

• In the top part of the enSuite device window, open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs and then select “Terminal interface”.

• Edit the device address of the EK205-M in the “All parameters” window in the line “Device address terminal interface (bus address)”.
  → Device address for Modbus protocol:
  The device address for the Modbus protocol may be a number between 1 and 247. The default value is “1”. Proceed as follows to edit the device address for the Modbus protocol:

• In the top part of the enSuite device window, open the path “Parameters” > “Interfaces” > “Terminal interface” by clicking on the relevant plus signs and then select “Modbus”.

1The “x” stands for the device software version, e.g. “1v0”.
The asterisk (*) stands for a lower-case letter which marks the version of the file, e.g. “a”.

• Edit the device address of the EK205-M in the “All parameters” window in the line “Modbus device address (slave address)”.

Further details on using the Modbus protocol are provided in document ⇒ [4] (page 1).
d) Setting time windows for future data retrievals
In the basic configuration now set up, you can define time windows during which data can be retrieved cyclically from the EK205-M via the RS485 bus. Time windows 3 and 4 are provided for operating the EK205-M with a directly connected terminal interface, with time window 3 being the one which is normally used. You can deactivate time windows which are not needed by setting the start and end of the time window to the same value.

• At the top of the device window, open the path “Parameters” > “Interfaces” by clicking on the relevant plus signs, and then select “Call time windows”.
• In call acceptance window 3, set the start to “00:00” and the end to “23:59” and then select the “Transfer changes to device” icon at the top of the enSuite window.

Click on the “Transfer changes to device” icon at the top of the enSuite window.
e) Data retrieval using the RS485 interface
Check the following points if data retrieval via the device connected to the RS485 interface does not now work:

• Are the wire straps between signals T+ and T- and between R+ and R- connected with the correct polarity as described in section 8.2.2.1.1 or 8.2.2.1.2?
  (Attention: the sequence of “+” and “-” is different for T+ and T- than for R+ and R-!)

• Is the power supply to the “Uext” terminals on the EK205-M switched on?

• Does the connected device send the device address set as described in 8.2.2.2 c) when the connection is established?

• Is the time window set as described in 8.2.2.2 d) active? You can check this as follows:
  – Start enSuite and establish the communication link to the EK205-M via the optical interface (⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
  – Select “Navigation” on the left-hand side and then “Parameterize online” at the bottom of the navigation window.
  – In the top part of the device window, open the path “Parameters” by clicking on the relevant plus sign and then select “Status” and the “Momentary status” tab in the right-hand window.
  – Check whether there is a line there with the entries “St.3”, “16” and “Call Win.3”.– If this is not the case, set the time window as described in section 8.2.2.2 d).

• Complete a reset on the terminal interface of the EK205-M:
  – Start enSuite and establish the communication link to the EK205-M via the optical interface (⇒ section 7.1 Setting up the communication link to the EK205-M via optical interface, p. 50)
  – Select “Navigation” on the left-hand side and then “Parameterize online” at the bottom of the navigation window.
  – In the top part of the device window, open the path “Parameters” > “Interfaces” > “Terminal interface” by clicking on the relevant plus signs.

– Enter the value “1” in “Reset terminal interface “ResI2”” and then click on the “Transfer changes to device” icon at the top of the enSuite window.
8.3 Data transfer verification
The communication link (e.g. call window, modem used) to a destination must be established before the data can actually be transmitted. You can program six separate connections.
To parameterize the EK205-M, you will require a connection cable for the optical interface as well as the enSuite program, which can be downloaded free of charge from www.elster-instromet.com.
The paths described below can be found in enSuite under: “Parameterize online”

“Parameters” > “Interfaces”
All connections are inactive by default and preset as follows, as can be seen in enSuite under: “Parameterize online” > “Parameters” > “Interfaces” > “Call time windows”

8.3.1 Time window connection
The major parameters for activating a time window connection are listed below. For parameterization, go to the following sub-menu in enSuite:
“Connections” > “Connection 1” to … > “Connection 6”

monthly)
Start| Start of a time window connection (e.g. daily at 00:00 or another time)
 End| End of a time window connection (e.g. daily at 23:59 or another time)
StCon| Current status of this connection

If the conditions for activating the time window connection are satisfied, then the interface is opened and the EK205-M is ready for reception. If a modem is connected to this interface, the EK205-M will only be ready for reception after a further 30 seconds.
The conditions for activating a time window connection are as follows:
– Is the current device time within the parameterized time window?
– Does the supply to the EK205-M correspond with the parameterization of the connection?
If the supply type “Always” is used, the EK205-M is active during the set time window regardless of the voltage supply! In battery mode (in the same way as for supply type “Battery”), this can result in a significant reduction in the battery service life to just a few months!
The forecast remaining battery service life “Bat.R” does not take account of this case.

9.3.6 Access rights
The EK205-M has the following access parties.

Access|

Meaning

---|---
C| Calibration officer
CDL 14| Calibration Manual
A| Administrator
Cu| Customer
–| No access

Every access party has a lock and a matching key.

The access rights apply for both inputs by keyboard and for access via the optical, electrical (fixed wired) or integrated modem interface. If the lock is closed, all attempts to set values prompt a corresponding error message (see section 9.3.5, Error messages when entering values).
Reading values via the interfaces is also only possible within the meaning of data protection if a lock is open.
9.3.6.1 Calibration lock
The calibration lock serves to secure calibration law parameters. These include all values that influence volume counting and volume conversion.
The calibration lock is designed as a key that is placed within the EK205-M housing below the circuit board cover. It can be secured with an adhesive label (see section 6.3.1.1, Opening the calibration lock).
The calibration lock is opened by actuating the key (the P symbol flashes in the display) and closed again by actuating it a second time (P symbol extinguishes). Closing is also possible by deleting the St.ES value (see section 9.4.6, Strg. tab (control)) via the keyboard or interface.
Using the enSuite software, it is also possible to set a time in minutes after which the calibration lock closes automatically.
In particular for applications outside the German calibration obligation or the MID, the protection degree of all parameters can be changed on request.As such, parameters that are below the calibration key by default can also be protected with the administrator key or calibration logbook.
Certification data log
The certification data log is activated by default but can be deactivated as an option. The parameters affected are then below the calibration lock.
Using the certification data log in accordance with PTB-A 50.7, some calibration law-relevant parameters can also be changed when the calibration lock is closed. The requirements for this are:

• The administrator lock must be opened (see below).
• At least three free entries must be available in the certification data log. The parameters affected according to the factory settings are:
• I1 cp value for input 1,
• MPer measurement period
• K K number mode
• A delete measurement archive
• I1 mode for input 1
• QMax maximum load (plausibility check in encoder mode)

For every change of a parameter under CDL with a closed calibration lock, a data row for the value is entered before and after the change.
If the certification data log is full, it can be deleted when the calibration lock is open using the
ClCDL command. (see section 6.3.1.13)
Administrator lock and customer lock
Administrator and customer lock are used to secure all calibration law data that are not relevant, but that should not be changed without authorization.
The locks can be opened by entering a code (the “key”) under Cod.A or Cod.C and closed by entering “0” for St.AL or St.CL.
These values can be found under the path: Admin ? Device settings ? Access or Serv.? Device settings? Access
There, a time can also be set in minutes for each lock after which it closes automatically.
9.4. Content of the data register
9.4.1 Access rights

12.2 Disposal
EK series volume conversion devices are covered by the WEEE Directive and bear the WEEE symbol . The important thing to note here is that end-of-life devices must be processed by an individual or collective recycling and disposal system. As EU member states have transposed the WEEE Directive differently into national law, the regulations for returning end-of-life devices vary.
Please ask your Honeywell sales partner about the regulations for returning your devices.
Environmentally sound disposal under the WEEE Directive
The WEEE Directive 2012/19/EU was adopted by the European Commission. WEEE stands for “Waste Electrical and Electronic Equipment” (or e-waste). Its aim is to provide a statutory framework to achieve the sustainable production and sustainable use of electrical and electronic equipment by re-use, recycling and other forms of the recovery of end-of-life electrical and electronic equipment. The intention is to reduce the share of this equipment in household waste and to collect raw materials properly for recovery.
Remove the battery before shipping or disposing of the device.
Please note that batteries require special waste treatment. They should therefore be removed before shipping an EK series volume conversion device and sent to a collection point or disposed of by a specialist contractor.
See section 10.2.1 “Replace and connect device batteries”
