CHAPTER 1 INTRODUCTION EnergyAxis Gas Module ― User Guide Page 1 Elster Integrated Solutions • Draft Rev A Nov. 2007 Chapter One Introduction The EnergyAxis Gas Module is the heart of Elster Integrated Solutions’ portfolio of products for automated metering infrastructure (AMI). About this Document The EnergyAxis Gas Module User Guide provides instructions for installing and troubleshooting transponders. It also includes an overview of both AMI in general and EnergyAxis technology in particular. Actual procedures are covered in two sets of chapters. One is set for direct mounted transponders (transponders connected directly to the meter index) and the other set is for remote-mounted transponders (transponders mounted some distance away from the meter index): • Chapters 3 and 4 discuss the installation, operation and programming of direct-mounted transponders. These are typically used for residential applications with 1ft and 2 ft meters. • Chapters 5 and 6 cover installation, operation and programming of remote-mounted transponders. These are typically used for commercial applications with 5 ft and 10 ft meters. Audience This document is designed for utility industry installers and supervisory staff. In order to establish appropriate levels of detail for the material, this document assumes the following:  The user is proficient in installing and EnergyAxis transponders and possesses all the skills necessary to conduct meter installation reading meters of the type currently compatible with and reading by conventional means.  The user has little or no prior expertise in the EnergyAxis AMI technology.  The user is familiar with common data entry devices and techniques.  The user will receive (or has received) instructions for operation of an appropriate EnergyAxis programmer elsewhere (in a separate document or training program).

CHAPTER 3 VRT DIRECT GAS-METER TRANSPONDER OVERVIEW EnergyAxis Gas Module ― User Guide Page 3 Elster Integrated Solutions • Draft Rev A Nov. 2007 Chapter Two Automated Meter Reading Overview The EnergyAxis system uses radio frequency (RF) signals to allow utility personnel to automate meter reading activities. This technology is called automated meter infrastructure (AMI). This technology greatly increases the speed at which routes can be covered with a high degree of accuracy. Basic AMI Components An automated meter reading system requires the following basic components:  Endpoint—The EnergyAxis Gas Module interfaces with the meter index drive, counts the number of drive dial (proving dial) rotations, receives commands from an interrogator and transmits the index reading and other meter data.  Interrogator—At its simplest, the interrogator remotely reads meter data transmitted by transponders. At more sophisticated levels an interrogator may also program transponders, store route data and verify transponder conditions and data, among other functions.
VRT DIRECT GAS-METER TRANSPONDER OVERVIEW CHAPTER 3 Page 4 EnergyAxis Gas Module ― User Guide Elster Integrated Solutions • Draft A Nov. 2007 EnergyAxis AMI System Overview Elster Integrated Solutions EnergyAxis system portfolio of products permits the remote recording of tamper conditions and the linking of meter latitude and longitude data using the Global Positioning System (GPS). In every meter reading transmission, gas modules send total consumption data as well as interval consumption data for each of the last 24 hours. The data are stored in the EnergyAxis collector as well as the module’s nonvolatile memory, protecting the data against loss. All the data are available for on-request reading. EnergyAxis Gas modules communicated with an unlicensed frequency hopping spread spectrum RF technology compliant with FCC Rules, Part 15 and Industry Canada RSS-210 in a rage of 902 MHz to 928 MHz. How the EnergyAxis System Works Installing EnergyAxis electricity meters builds the infrastructure that allows gas AMI metering to be added at an incremental cost. Therefore, expanding the EnergyAxis network to cover gas metering requires the installation of the EnergyAxis Gas module to the gas meter. The information acquisition, storage and handling process includes several basic elements: Meter interface. Using a mechanical-to-digital interface, the EnergyAxis Gas Module senses the output of a utility meter, translates this into electronic form and stores it in the transponder’s memory. Tamper sense and flagging. When the EnergyAxis Gas Module is installed and programmed, a baseline orientation for its internal tamper sense is set. Any deviation from that baseline setting will trigger a tamper indication. Transponder data acquisition. The EnergyAxis Gas Module is programmed with a unique serial number at the time of manufacture. Upon installation on a meter, the current (or baseline) meter index reading is also programmed into the transponder’s memory. As the meter measures consumption and the index is advanced, the index reading stored in the transponder’s memory is automatically updated. The transponder also records changes to the tamper detection sensor. Pressure-compensation factor. For EnergyAxis Gas Modules a pressure-compensation factor can also be programmed into the transponder memory ensuring the transponder readings match the pressure-compensated mechanical index reading.
CHAPTER 3 VRT DIRECT GAS-METER TRANSPONDER OVERVIEW EnergyAxis Gas Module ― User Guide Page 5 Elster Integrated Solutions • Draft Rev A Nov. 2007 Chapter Three EnergyAxis Direct Gas-meter Transponder Overview The EnergyAxis Direct Gas-meter Transponder (DGT) is designed for use with most residential diaphragm meters. EnergyAxis Direct Gas-meter Transponders for residential meters are available in three distinct types: • Type A = American Meter Company® products • Type R & R415 = Rockwell / Equimeter / Invensys® • Type S = Sprague / Schlumberger / Actaris / Metris® The EnergyAxis DGT can be programmed for use with a fixed factor, pressure-compensated index. The EnergyAxis DGT maintains the current time and date, which are used to manage the recording of real-time data for retrieval as required during the normal read cycle. In addition to maintaining index reading, the transponder: • Stores 35 daily index readings in separate electronic indexes recorded at the start of the utility day. (The utility day start time is programmable). • Maintains interval data for each 15 minute, 30 minute or 60 minute interval (default). Up to 35 days of 60 minute interval data will be stored by our module. Type S Sprague/ Schlumberger/ Actaris/Metris® Type R & R415 Rockwell/ Equimeter/ Invensys® Type A American Meter Company®

CHAPTER 3 VRT DIRECT GAS-METER TRANSPONDER OVERVIEW EnergyAxis Gas Module ― User Guide Page 9 Elster Integrated Solutions • Draft Rev A Nov. 2007 How the EnergyAxis Direct Gas-meter Transponder Works When a EnergyAxis DGT is installed on a meter the installer programs the mechanical index reading into the transponder. Converting Mechanical Count into Electronic Form During normal operation, the mechanical index accumulates its count. The transponder keeps track of the index reading by counting the number of rotations of the index’s drive dial. Storing Readings Once a day, at a pre-programmed time specified by the utility, the transponder stores the current index reading into the electronic index for that day. The transponder maintains daily reading history for the past 35 days. Between 1 an 4 interval values per hour—can accumulate consumption in separate electronic indexes as well. Operation Cycle To maximize battery life, the EnergyAxis gas-meter transponder changes from its normal, low-power quiescent state every 2 seconds into an intermediate power state for 5.5 milliseconds in order to perform three tasks: • Update the electronic indexes for the meter reading, daily reading and interval reading • Poll the tamper detection switch • Check to see if a valid interrogation signal is being received If and when a valid interrogation signal is received, a two-way communication link is established. Meter reading data is then transmitted to the interrogator. Data collected by an interrogator is validated and stored for uploading to Route Manager Software later.

Remove the gasket and any adhesive material from the meter. • Use a scraper or putty knife. 3. Align index wriggler with transponder wriggler, as shown below. 4. Attach the index to transponder. • Use two (2) appropriate index screws. CAUTION: Do not over tighten index screws. Checking Mechanical Operation This procedure will verify the attached index rotates freely and without resistance. 1. Rotate the index drive dial 3 times clockwise. 2. If it turns easily, rotate the drive dial 3 times counterclockwise. • This will remove counts or subcounts from the mechanical index.) • If it does not turn easily, first rotate the drive dial 3 times counterclockwise to remove subcounts from the mechanical index. Second, unscrew the index/transponder assembly and repeat from Step 3 of the previous section. NOTE: Subcounts added to the electronic index during this procedure will be cleared when the index reading is programmed into the transponder. Type A Type R Type S Type R415
VRT DIRECT GAS-METER TRANSPONDER INSTALLATION CHAPTER 4 Page 14 EnergyAxis Gas Module ― User Guide Elster Integrated Solutions • Draft A Nov. 2007 Checking Mechanical Index to Electronic Index Operation This procedure will verify the electronic index is properly recording counts and subcounts corresponding with those of the mechanical index. 1. Rotate the transponder wriggler till the drive dial is in the 12 o’clock position. 2. Electronically read the transponder subcounts. • Use an Handheld or other suitable interrogator/programmer. • Remember the subcount value. 3. Facing the index, rotate the drive dial 3 times counterclockwise. Stop at the 12 o’clock position. 4. Electronically read the new transponder subcounts. • Use an Handheld or other suitable interrogator/programmer. • Observe the new subcount value and calculate the difference between it and the starting subcount value. 5. If the new subcount value is exactly 3 subcounts higher than the original reading, proceed to step 8. 6. If the new subcount value is less than 3 subcounts higher, consider whether the subcounts may have rolled over during the test. • If it appears the discrepancy is due to rollover, proceed to step 8. 7. If the new subcount value is less than 3 subcounts higher, repeat this procedure from Step 1. • If the procedure fails a second time, replace transponder with a new one.

CHAPTER 4 VRT DIRECT GAS-METER TRANSPONDER INSTALLATION EnergyAxis Gas Module ― User Guide Page 15 Elster Integrated Solutions • Draft Rev A Nov. 2007 8. By using an Handheld or other suitable interrogator/programmer, verify that the pre-divider is correct. (The pre-divider for a 1-ft drive is 100 and the pre-divider for a 2-ft drive is 50; refer to the Appendix for the definition of pre-divider). 9. Remove any subcounts or counts from the mechanical index by rotating the drive dial clockwise by the same number of counter-clockwise rotations that were placed on the mechanical index in the previous steps. Mounting the Transponder/Index Assembly NOTE: Be sure to have your transponder/index assembly, screwdriver, index cover and index cover gasket within easy reach before starting this procedure. 1. For Rockwell 415 Transponders Only: Install the meter adapter to the meter using the two 6/32 supplied in the assembly. Note: Make sure the gears on the adapter and meter are properly meshed. 2. Visually align transponder wriggler with meter wriggler or meter adapter (drive dog). • If wriggler cannot be put in a fixed position, position it correctly by rotating the drive dial with your finger. 3. Mate the transponder wriggler with the meter wriggler or meter adapter (drive dog) and hold the mated assembly against the meter. 4. While holding the assembly against the meter, gently try to turn the drive wheel clockwise, then counterclockwise. • If the drive wheel meets resistance in both directions, it is properly mated. Proceed to Step 4. • If it meets no resistance in either direction, and can rotate freely through an angle of 360 degrees and beyond, then make sure the meter is completely free of old gasket material and forcefully press the transponder into the meter. Repeat this step (Step 3). If the unit still does not correctly engage with the meter, return it to Elster Integrated Solutions. meter Adapter 6/32 mounting screw
VRT DIRECT GAS-METER TRANSPONDER INSTALLATION CHAPTER 4 Page 16 EnergyAxis Gas Module ― User Guide Elster Integrated Solutions • Draft A Nov. 2007 • For American Meter Transponders Only: If the American Meter transponder meets resistance in one direction then turns 360 degrees the other way before again meeting resistance, it is not properly mated. Repeat from Step 1. CAUTION: It is very important that the wriggler on the transponder is correctly engaged onto the meter. If it is not, it could produce an erroneous indication during utility leak test procedures that monitor drive dial (proving dial) movement. Incorrectly engaged wrigglers could also cause meter damage. CORRECT EXECUTION OF STEPS 1, 2 and 3 IS CRITICAL. 5. Verify that the gasket material on the index cover is free of rips or tears. • If it is not, remove the damaged gasket from the index cover and replace with a new one. 6. Place the index cover and index cover gasket onto the transponder/ index assembly. • Verify the index cover is properly oriented with its vent holes at the bottom. • See photos below for orientation cues. 7. Screw the transponder/index/cover assembly to the meter and tighten bolts to secure assembly to meter. • Use the appropriate mounting bolts provided. • Recommended torque range is 16-24 in-lbs. 8.

Remove the semi-detached label from the transponder and attach it to your paperwork. Programming the EnergyAxis Direct Gas-meter Transponder Although transponders may contain default or utility-specified values that are programmed during manufacturing, it is important to program certain data only after the transponder has been installed in the field: • Transponders can accumulate subcounts during shipping, handling and installation due to the movement of its wriggler. • The transponder’s tamper sensing switch must be told which orientation should be considered its normal (not tampered) condition. Therefore, all transponders (even those mated with indexes set at 0000) should be programmed after installation on the meter. When the transponder is programmed, it also automatically sets the tamper flag to “false” or “not tampered,” establishing its normal condition in the transponder’s memory. NOTE: Even transponders factory-installed on meters must be programmed at the time the meter is installed in the field. Programming Procedure NOTE: For specific instructions for programming transponders, please refer to the appropriate interrogator/programmer user guide. NOTE: Always verify the display of the utility-lan id on the Handheld with that same value on the module itself to insure that programming is being completed for the correct module.. NOTE: If required, be sure to have on hand the pressure compensation factor. (Obtain from Elster Integrated Solutions.) 1. Read the transponder. • Place interrogator/programmer close to the transponder, especially if other transponders are nearby. • If no other transponders are within 6 feet, use Wildcard function to find transponder serial number. • If other transponders are within 6 feet, enter the serial number of the desired transponder. 2. Visually read the meter’s mechanical index.
VRT DIRECT GAS-METER TRANSPONDER INSTALLATION CHAPTER 4 Page 18 EnergyAxis Gas Module ― User Guide Elster Integrated Solutions • Draft A Nov. 2007 3. Program the electronic index to match the meter ‘s mechanical index. • This will also reset the transponder subcounts to zero. 4. If required, program the pressure compensation factor now. • Compensation factors are unique for specific indexes and can be obtained by contacting Elster Integrated Solutions Customer Service Department at (919) 250-5700. 5. Read the transponder. • If the electronic index matches the meter ‘s mechanical index, installation is complete. • If the electronic index does not match the meter ‘s mechanical index, repeat procedure from Step 1. • If the transponder still does not program, replace it with a new one.

APPENDIX Page 20 EnergyAxis Gas Module ― User Guide Elster Integrated Solutions • Draft A Nov. 2007 How it Works The EnergyAxis RGT is designed for use with commercial gas meters where the meter/index design prohibits direct transponder attachment. A “pulser” circuit board is interfaced with the index gears to provide an electronic “pulse” that translates each turn of the mechanical gear into electronic pulses. These pulses are sent via a cable to the transponder where they are recorded as consumption values. Most applications accommodate connection of the transponder within one foot of the meter. However, certain applications (where the meter is obscured by metallic materials that can block radio signals, for example) a remote transponder with a longer cable may be special ordered so that the transponder can be mounted farther away from the meter in a position more favorable for interrogation. Features and Capabilities The EnergyAxis RGT can be programmed for use with a fixed factor, pressure-compensated index. The transponder maintains current time and date, which are used to manage the recording of real-time data for retrieval as required during the normal read cycle. In addition to maintaining index reading, the transponder: • Stores 35 daily index readings in separate electronic indexes recorded at the start of the utility day. (The utility day start time is programmable.) • Maintains up to four time-of-use (TOU) electronic indexes that each have programmable start and stop times. EnergyAxis Remote Gas-meter Transponder Construction The EnergyAxis RGT is available for American Meter 5-foot and 10-foot meters. The transponder has a high impact plastic housing with rubber gasket and it includes the following internal components: • RF transmitter • RF receiver • Tamper switch • Transmit and receive antennas • Battery • Electronic components

APPENDIX Page 34 EnergyAxis Gas Module ― User Guide Elster Integrated Solutions • Draft A Nov. 2007 EnergyAxis RGT Programming (All) NOTE: The procedure for programming the EnergyAxis Remote Gas-meter Transponder is identical to that used for programming the EnergyAxis Direct Gas-meter Transponder as described earlier in this manual. Although transponders may contain default or utility-specified values that are programmed during manufacturing, it is important to program certain data only after the transponder has been installed in the field: • Transponders can accumulate subcounts during shipping, handling and installation due to the movement of its wriggler. • The transponder’s tamper sensing switch must be told which orientation should be considered its normal (not tampered) condition. Therefore, all transponders (even those mated with indexes set at 0000) should be programmed after installation (on meter). When the transponder is programmed, it also automatically sets the tamper flag to “false” or “not tampered,” establishing its normal condition in the transponder’s memory. NOTE: Even transponders factory-installed on meters must be programmed at the time the meter is installed in the field. Programming Procedure NOTE: For specific instructions for programming transponders, please refer to the appropriate interrogator/programmer user guide. NOTE: If required, be sure to have on hand the pressure compensation factor. (Obtain from Elster Integrated Solutions.) 1. Read the transponder. • Place interrogator/programmer close to the transponder, especially if other transponders are nearby. • If no other transponders are within 6 feet, use Wildcard function to find transponder serial number. • If other transponders are within 6 feet, enter the serial number of the desired transponder. 2. Visually read the meter’s mechanical index. 3. Verify that the transponder is programmed for the proper index drive. If it is not re-program it. 4. Program the electronic index to match the meter ‘s mechanical index.
CHAPTER 7 TROUBLESHOOTING EnergyAxis Gas Module ― User Guide Page 35 Elster Integrated Solutions • Draft Rev A Nov. 2007 • This will also reset the transponder subcounts to zero. 5.. If required, program the pressure compensation factor now. • Compensation factors are unique for specific indexes and can be obtained by contacting Elster Integrated Solutions Customer Service Department at (919) 250-5700. 6.. Read the transponder. • If the electronic index matches the meter ‘s mechanical index, installation is complete. • If the electronic index does not match the meter ‘s mechanical index, repeat procedure from Step 1. • If the transponder still does not program, replace it with a new one.
Page 36 EnergyAxis Gas Module ― User Guide Elster Integrated Solutions • Draft A Nov. 2007 Appendix EnergyAxis Direct Gas-meter Transponders can be programmed (at the factory or in the field) with values specified by the utility. This Appendix highlights some of the types of data that can be programmed at the factory and the range of selections within each type. For comprehensive discussion of all programmable transponder data, please refer to the applicable interrogator/programmer user guide. Pre-Divider The number of subcounts recorded with each revolution of the drive dial on 1-ft3 and 2-ft3 indexes is one. A 1-ft3 index requires 100 revolutions to yield 100 ft3 (1 count) and a 2-ft3 index requires 50 revolutions to yield 100 ft3 (1 count). Therefore, the pre-divider for a 1-ft3 index is 100 and for a 2-ft3 index it is 50. Pressure-Compensation Factor When a transponder is used in conjunction with a pressure-compensated index, a pressure-compensation factor can be programmed into the transponder memory by the utility at the time of installation to ensure that the electronic index reading agrees with the mechanical index. Pressure-compensation factors are unique for specific indexes and can be obtained by contacting Elster Integrated Solutions’ Customer Service Department at (919) 250-5700.
