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.

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.

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.

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.

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.

• 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.

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.

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.

• 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. Install the tamper seals into the index cover receptacles.

9. 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.

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

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.

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.
