Installation & Operation Manual INTRODUCTION The Data Industrial 340 BN/MB Btu Energy Transmitter from Badger Meter is an economical, compact device for hydronic sub-metering applications. It uses an RS-485 connection for Modbus® and BACnet communication protocols and a solid state switch for pulse output representing either flow or energy.
Data Industrial® 340 BN/MB BTU Energy Transmitter Surface Mount Installation The 340 BN/MB Btu Energy Transmitter may be mounted to the surface of any panel using double-sided adhesive tape or by attaching fasteners through the holes in the mounting flanges of the unit. 1.60” (40.6mm) 3.65” (92.7mm) Output Sensor Input Output LED Data Industrial Btu ENERGY METER Model: 340 BN/MB S/N 340- 005100 D.I.C.

Installation & Operation Manual DIN Rail Mounting Optional clips snap onto the mounting flanges allowing the 340 BN/MB Btu Energy Transmitter to be attached to DIN 15, 32, 35 mm DIN rail systems. Figure 3: DIN Rail Mounting Temperature Sensor Installation Badger Meter offers several styles of 10k Ω Thermistors and 100 Ω Platinum RTDs in both direct immersion and Thermowells. The style selected depends on system requirements and pipe size.
Data Industrial® 340 BN/MB BTU Energy Transmitter Hot Tap For pipes that cannot be drained even for initial installation, we offer a Hot Tap version. Model THT – available in the 10k Ω Thermistor version only. Figure 6: Hot Tap Electrical Installation All connections to the 340 BN/MB Btu Energy Transmitter are made to screw terminals on removable headers.
Installation & Operation Manual Power Supply Wiring The 340 BN/MB Btu Energy Transmitter requires 12-24 Volts AC or DC to operate. The power connections are made to the ORANGE header. The connections are labeled beside the header. Observe the polarity shown on the label. If a Badger Meter plug-in type power supply (Series A-1026 or A-503) is used, connect the black/white striped wire to the terminal marked positive (+) and the black wire to the terminal marked negative (–).

Installation & Operation Manual Temperature Element Wiring Appropriate wire types and proper shielding is required for accurate temperature readings. Since Btu calculations are based on Delta T cable, in order to maintain a balanced system, T1 and T2 wire runs should be kept to approximately the same length, not to exceed 500 feet. Thermistors Badger Meter thermistors are not polarity-sensitive, therefore, wire color is unimportant.

Installation & Operation Manual Connection to the RS-485 network should not be made until the 340 BN/MB Btu Energy Transmitter has been configured per the instructions in "Programming" on page 14. See RS-485 Network Configuration on page 19. Communications Cable Wiring Field configuration requires a Data Industrial programming kit (consisting of a custom cable and software) and a PC running Windows 9x, ME, NT, 2000 or Windows 7.
Data Industrial® 340 BN/MB BTU Energy Transmitter PROGRAMMING Connecting Via DIC COM Port Programming the 340 BN/MB Btu Energy Transmitter is accomplished by installing Badger Meter programming software on a computer and entering data on templates of the Windows based program. 1. Load the interface software into the computer. 2. Power the 340 BN/MB Btu Energy Transmitter with 12-24V AC/DC. 3.
Installation & Operation Manual 6. Once 340BN/MB has been selected, the appropriate COM port can be selected from the Configuration tab. Figure 17: Select Set COM Port Figure 18: Select the COM Port 7. If the COM and Device type have been properly selected, the “---” will be replaced with values. NNOTE: If this does not occur, communication has not been established and you cannot continue to the next step. If it does not connect automatically try clicking on Poll Now.
Data Industrial® 340 BN/MB BTU Energy Transmitter NNOTE: If communication still does not occur and you are using a DB9 to COM 1 or COM2, try using a USB to COM adapter. This will usually create a new COM port that was not previously listed. Windows Device Manager can be helpful in determining the actual COM ports that are available. Figure 19: Device Manager Select this new port created by the adapter and the screen should change as shown (Figure 20). Notice that the “---“ are replaced with values.
Installation & Operation Manual 8. When communication has been confirmed, click on the Parameters button. The Parameters screen is displayed. Figure 21: Parameters Screen 9. From this screen set up the following: 1. Flow Sensor Type, Scaling and Units 2. Temperature Sensor Type, Units, Mode and Zeroing 3. Energy Calculation Units of Measure 4. Filter Coefficients (Flow and Energy averaging for reading stability) 5. Scaled Pulse Output Resolution and Pulse Width 6.
Data Industrial® 340 BN/MB BTU Energy Transmitter Flow Sensor Section Figure 23: Pulse or Sine For most Data Industrial sensors, the sensor type is “Pulse”, and the “K” and “Offset” values can be found in the respective Flow Sensor Manual. “Sine” is used for zero-crossing flow sensors (some turbine meters, etc.) Several flow rate and flow total units of measure can be selected from the pull-down menu.
Installation & Operation Manual The Zero Temp Diff is a very powerful feature in this product which allows any inaccuracies of drift in the temperature sensors, or the 340 BN/MB Btu Energy Transmitter temperature measurements, to be cancelled out. This correction can be either manually typed in or if the temperature sensors are known to be at exactly the same temperature, the Zero Temp Diff button can be used to automatically zero the difference between the two readings.
Data Industrial® 340 BN/MB BTU Energy Transmitter RS-485 Network Configurations The RS-485 Section can be configured in three ways: • Pulse Out Only – RS-485-OFF • Modbus • BACnet The following sections explain each in detail. RS-485 Network Configuration – Pulse Out Only Figure 28: Pulse Out Only Option If the Modbus or BACnet communications are not going to be used, the Pulse Out Only setting can be selected. This will disable the RS-485 Network.

Data Industrial® 340 BN/MB BTU Energy Transmitter RS-485 Network Test Figure 31: RS-485 Test The Configuration Software has an RS-485 test program. Although it uses Modbus settings, it is testing RS-485 communication. The test requires connection to a COM port using the Data Industrial A302-20 RS 485 to RS-232 convertor cable. This cable can also be helpful with other diagnostics programs and devices that use an RS-232 port to communicate.
