Page 8: Creating And Exporting A Gas-Net Parameter Data Record: Brief Description
Parameterizing with GW-GNET+ 1.1 Creating and Exporting a gas-net Parameter Data Record: Brief Description To create a completely new gas-net parameterization, proceed as follows: Start GW-BASE from the Windows environment by double-clicking the lantern icon. Invoke the GW-GNET+ module by clicking the New – Create gas-net parameterization tool in the toolbar. - Page 9 Parameterizing with GW-GNET+ When creating a new parameterization with GW-GNET+, you are offered several standard parameterization options. These standard parameterizations are consistent and contain all necessary references. This, of course, also applies to the parameterization preset by the manufacturer before delivery. If you delete or fundamentally change an input value being used in a different context within a parameterization, all linkages to this value become invalid and are automatically deleted by the parameterization program.

Page 10: Importing And Editing A Parameterization: Brief Description
Parameterizing with GW-GNET+ Connect the DSS data interface at the device to a COM interface of the computer using a parameterization cable. Turn the calibration switch at the device to “open”. 10. Mark the parameter data record and select the Data – Export menu item from the main or context menu of GAS-WORKS. - Page 11 Parameterizing with GW-GNET+ As soon as the reading in has been finished, close the communication program via the File – Exit main menu item. The parameter data record is filed in the GAS-WORKS worksheet under the specified file name. Before starting GW-GNET+, you have to file this data record away in the hierarchy, as worksheet data records cannot be processed further.

Page 12: Extras: Gw-Gnet+ Service Programs
Parameterizing with GW-GNET+ 1.3 Extras: GW-GNET+ Service Programs The GW-GNET+ program includes some additional service programs fulfilling different tasks relating to gas-net devices. The range of available service programs depends on the gas-net device type. For instance, the following tools are available for flow computers: Edit parameterization for changing the parameterization during an established data connection to the device. - Page 13 Parameterizing with GW-GNET+ Proceed as usual: 1. Start GW-BASE on your laptop computer. 2. Connect the DSS interface of the gas-net device to a COM interface of the laptop using a parameterization cable. 3. Start the communication program by clicking the Import – Data interface tool in the GW-BASE toolbar.

Page 15: Installation
Installation 2 Installation 2.1 Mounting the gas-net F1 The gas-net F1 device is designed for mounting in a 19”-cabinet and is available with mounting widths of 1/3 or 1/2. Please pay attention to a mounting depth of 170 mm (with connectors: approximately 220 mm) to guarantee the accessibility of the terminals on the back. - Page 16 Installation device. However, these terminals have to comply in part with the Ex-regulations and must possibly also be sealable. 2.2.1 Power Supply and Earthing Operate the gas-net F1 device with a nominal voltage of 24 V DC. – The connection of 24 V is implemented via the terminals on the back of the device and must be protected externally against short circuits with 1 A.

- Page 19 Installation 2.2.2.3 EXDE6 Input Board Important note: The EXDE6 input board is approved as an associated electrical apparatus of category ib according to DIN EN 50020 with intrinsically safe circuits. This is why signal transmitters located in hazardous areas (e.g. zone 1) can be connected to this board.
- Page 20 Installation 2.2.2.5 AE12 Input Board The AE12 input board offers twelve analog inputs for the connection of measuring sensors with 0/4..20 mA output signals. Connect the inputs via terminals I1+ to I12+ with the common ground I-.

- Page 22 Installation 2.2.3.3 TCP/IP Interface (optional) The TCP/IP interface is an RJ45 socket at the back of the device. It facilitates the communication via Ethernet with 10/100 MBit/s and thereby integrates the device in a standard network installation. In addition to time synchronization based on the NTP protocol, remote inquiries and the Modbus-TCP protocol for exchanging data with external devices are also possible via the TCP/IP interface.

Page 27: Commissioning
Commissioning 3 Commissioning This chapter briefly describes the most important aspects of commissioning gas- net flow computers. All parameters are listed in the annex to the first volume of the Flow Computer gas-net F1 documentation. 3.1 Parameter Protection against Unauthorized Access The functionality of a gas-net F1 can be completely configured via a parameter data record. -
Page 28: Parameterization
Commissioning 3.2 Parameterization Use a PC or laptop computer to create a complete parameterization or to modify existing parameters (except for a few). Create the parameter data record with the GW-GNET+ parameterization software. The calibration switch has to be open during the import of a complete parameterization via DSS data interface. Note: Please refer to Chapter 1 for brief instructions on the parameterization by means of GW-GNET+. - Page 29 Commissioning Brief instructions on how to check the device configuration: When being in the basic display, invoke the module listing by pressing the Menu key twice. Press the rightward arrow key until you have selected the System entry. Press the Enter key. The main display of the System module is invoked, showing device identification data (software variant, software version, serial number, check sum...).

Page 31: Commissioning The Integrated Rdt
Commissioning 3.3 Commissioning the Integrated RDT Parameterize the settings for the integrated RDT (together with all other parameters of the gas-net device) using the GAS-WORKS module GW-GNET+. Please pay attention to the consistency of the parameter data record; it is especially important to choose the correct modem. - Page 32 Commissioning Invoke the DSfG menu (System module) at the gas-net device, if this hasn’t happened yet. You may view the station list here and compare it with the planned bus configuration to check. Call your center and verbally announce the connection test. Switch the device off and immediately on again;...
- Page 33 Commissioning GSM Wireless Modem: Important note: Before starting with the commissioning of the integrated RDT, make sure the accurate PIN number of the SIM card has been set in the parameterization of the gas-net device (Integrated RDT module). The reason is that the entry of a wrong PIN is only possible twice;...
- Page 34 Commissioning view the station list here and compare it with the planned bus configuration to check. Call your center now and announce the connection test. If a routing job has already been pending, the RDT establishes the connection to the center. If this is not the case, you have to trigger an event that induces the RDT to call first;...
- Page 35 Commissioning with the planned bus configuration to check. Now plug the network connector in the corresponding socket at the gas-net device. Call your center and ask for the connection test. The center staff now have to establish a connection to the IP address of your RDT with their data polling tools (which must support DSfG connections via network) and check the data polling.

Page 37: Maintenance
Important: The old battery must be disposed properly; i.e. it must either be returned to the distributor (Elster) or handed in at special battery take-back facilities. To exchange the battery, you need to open the housing of the gas-net device. - Page 38 Maintenance Note: When inserting the battery, pay attention to the correct polarity: The positive pole (+) must point downwards! A wrong polarity will not be noticed at first, but during the next power failure that lasts more than 15 minutes the device data will be lost.
