CHAPTER 1

Getting Started

               The 100G is Itron's latest gas encoder-receiver-transmitter (ERT®) module.

               ERT modules are radio-frequency (RF) devices that transmit meter data. The RF meter data
               can be received by a reading device that is within transmission distance of the ERT. Itron's
               100G ERT module has increased output power over legacy gas ERT modules for increased
               RF transmission distance.

               This installation guide shows you how to install the 100G ERT module on meters from a
               variety of manufacturers. To ensure you have a meter that is compatible with the 100G ERT
               module, please see the Meter Compatibility List on page 2.


Transmission Modes
               Once installed, the 100G ERT module has three available transmission modes:
                 •   Fixed Network Mode In this mode, a 100G ERT module transmits a high-powered
                     RF message every 60 seconds. Output power in this mode is 250 milliwatts or
                     +24dBm; expected battery life is 20 years.
                 •   Mobile and Handheld Mode In this mode, a 100G ERT module transmits a
                     medium-powered RF message every 15 seconds. Output power in this mode is 10
                     milliwatts or +10dBm; expected battery life is 20 years.
                 •   (Optional) Hard to Read Mobile and Handheld Mode In this mode, a 100G ERT
                     module transmits a high-powered RF message every 30 seconds. Output power in this
                     mode is 250 milliwatts or +24dBm; expected battery life decreases to 15 years in this
                     mode, however. The Hard to Read Mobile and Handheld Mode should only be used
                     for 100G ERT modules that are difficult to read under normal conditions, such as
                     modules installed on roof tops or in sub-basements.
               An FCC license is not required to read 100G ERT modules.

Chapter 2 American Meter Installation




              Replacement Screws
              Replacement screws used in this procedure must be slotted, zinc-plated, steel machine
              screws. Sizing options are shown below.

              For mounting 100G ERT Module assemblies on meters:
                •   Use 1/4 - 20 x 5/8-inch slotted, Fillister head screws.
              For mounting indexes on 100G ERT Module backplates:
                •   Use 8 - 32 x 3/16-inch slotted, round head screws.


              Preinstallation Preparations
              Before installing the 100G ERT Module on a meter, verify that:
                •   All Itron gas modules are 100G ERT Modules for your brand of gas meters.
                •   The model numbers of all meters on which the 100G ERT Modules will be installed
                    are included in the Meter Compatibility List.
              There are four major steps to installing the 100G ERT Module on a meter:
                •   Remove the index
                •   Assemble the 100G ERT Module
                •   Program the 100G ERT Module
                •   Attach the 100G ERT Module to the meter.
              These procedures are described in the following sections.

                         NOTE Be sure to properly dispose of all unused screws, old index covers,
                         gaskets, and other left-over materials. Do not leave any materials on customer
                         premises.




              Remove the Existing Index
              The first major step when installing a 100G gas ERT on an meter is to remove the index
              from the meter.

              To Remove the Index
                1. Remove any tamper seals from the meter.




6                                                                  Natural Gas Solutions 100G Installation Guide


                                                                                       Installation Prerequisites



                 2. Detach the index cover from the meter by removing the four screws holding it in
                    place.




                 3. Examine the index cover screws you just removed. Verify that they are 5/8-inch long
                    and are not corroded.
                        •   If the screws are 5/8-inch long, and are not corroded, keep them for later use.
                        •   If the screws are an incorrect length or are corroded, dispose of them properly.
                            Use 1/4 - 20 x 5/8-inch screws as described in Replacement Screws on page 6
                            instead.
                                        TIP You can use the index cover you just removed as a temporary storage
                                        location for screws.
                 4. Unscrew one index mounting screw completely.
                     Hold one hand beneath the index to catch the screw when it falls out of the index
                     assembly. If it does not fall out by itself, be sure to remove it.




                 5. Unscrew the other index mounting screw.

Chapter 2 American Meter Installation



                    While removing this screw, pull the index away from the meter to keep its backplate
                    (1) against the back of the screwhead (2). This prevents the screw from falling out
                    prematurely.

                                                                      1

                                                                      2




                6. Remove the screw from the index once it is completely free of its hole.
                7. Set the index aside for the moment. Place it where it will not be damaged; get filled
                   with dirt, rain, or snow; or fall to the ground or floor. The index will be used later in
                   this procedure.
                8. Examine the index screws you just removed. Verify that they are 3/16-inch long and
                   are not corroded.
                       •   If the screws are 3/16-inch long and are not corroded, keep them for later use.
                       •   If the screws are an incorrect length or are corroded, dispose of them properly.
                           Use 8 - 32 x 3/16-inch screws as described in Replacement Screws on page 6
                           instead.
                9. Use a putty knife or similar object to completely remove the old index gasket from the
                   meter (if applicable). All traces of the gasket must be removed before the ERT can be
                   installed.

                                                                                      Installation Prerequisites




               Assemble the ERT Module
               When installing a 100G ERT Module, the next major step is to create the endpoint module
               assembly by combining the endpoint backplate and cover with the meter index. Follow the
               procedure below to do so.

               To Assemble the ERT Module
                 1. Obtain a new 100G ERT Module.
                 2. Separate the ERT module backplate (1) from the cover (2).




                 3. Set the new ERT index cover aside for the moment. Place it where it will not be
                    damaged; get filled with dirt, rain, or snow; or fall to the ground or floor. The ERT
                    index cover will be used later in this procedure.
                                 IMPORTANT Before continuing with the installation, note the following
                                 information about American Meter indexes:

                        •   Index wrigglers on one-foot meters have drive slots.




Natural Gas Solutions 100G Installation Guide                                                                 9


Chapter 2 American Meter Installation



                       •   Index wrigglers on two-foot meters have drive posts.




                       •   An index may have mounting screw holes.




                       •   An index may have mounting screw slots.




                    If the index has mounting screw slots, skip steps 4 and 5 below. Continue with step 6.
                    If the index has mounting screw holes, perform steps 4 and 5 below, and then skip
                    steps 6 and 7.

                 4. If the index has mounting screw holes, place an index mounting screw (1) in the right-
                    hand mounting screw hole (2). Use one 8 - 32 3/16-inch screw for this step (you can
                    use an original mounting screw if it was the correct size and not corroded; otherwise,
                    use the correct size replacement screw).

                 5. Attach the screw to the ERT backplate's right-hand index mounting post just far
                    enough to hold the screw and end of the index in place.




                 6. If the index has mounting screw slots, screw an index mounting screw (1) one to two
                    turns into the ERT backplate's right-hand index mounting post (2). Use one 8 - 32 x
                    3/16-inch screw for this step (you can use an original mounting screw if it was the
                    correct size and not corroded; otherwise, use the correct size replacement screw).

              Once the ERT module has been assembled, the ERT must be programmed using the
              FC200SR with EndPoint-Link software. See the Endpoint-Link ERT Programming Guide
              (TDC-0411) for more information.

                          IMPORTANT You must perform the following programming procedure for
                          the ERT module to function properly.

              When programming the ERT module, you must take note of the drive rate shown on the
              index of American meters. Examples of 1-foot (1) and 2-foot (2) drive rates are shown
              below (a 0.05 cubic metre drive rate is not shown). Be sure to program the ERT based on
              the drive rate indicated on the index.

                                                                                     Installation Prerequisites




               To Program the ERT Module
                 1. Using the FC200SR, program the reading of the index that was on the meter into the
                    ERT module assembly.
                        •   For initial programming, hold the FC200SR approximately 1 foot away from
                            the 100G.
                        •   For reprogramming (30 days or more past initial programming), hold the
                            FC200SR approximately 4 to 5 feet away from the 100G.
                     Be sure to program the 100G to the correct mode for the reading technology what will
                     be used (for example, Fixed Network Mode, Mobile/Handheld Mode, or Hard to Read
                     Mobile/Handheld Mode). In Endpoint-Link Pro v5.0, you will have access to the one
                     mode that was defined by your system administrator.
                     During programming, the 100G ERT module is programmed to the nearest 100 cubic
                     feet; the last two digits (the tens and units) are programmed as zeros (0). Once
                     programming is complete, however, the ERT module assembly can be read to the
                     nearest cubic foot.
                 2. Slowly turn the ERT module drive wriggler two turns in the direction indicated on the
                    index drive rate. This lets you verify the ERT module is counting properly after
                    assembly.

                                 IMPORTANT Do not turn the drive wriggler faster than one turn per second.

                 3. Read the ERT module assembly using the FC200SR. Consult the EndPoint-Link ERT
                    Programming Guide (TDC-0411) or other applicable instructions for details on how to
                    read an ERT.
                        •   If this reading is higher than the one you programmed in step 1 above, the ERT
                            module assembly is counting correctly.
                        •   If the ERT module assembly reading is not higher than what was programmed
                            in step 1, replace the ERT module with a new one.


               Attach the ERT Module to the Meter
               After the endpoint has been programmed and is reading correctly, it must be attached to the
               meter. Follow the steps below to do this.

              To Attach the ERT to the Meter
                1. 5B 225 Meters Only If you are installing the ERT on a 5B 225 aluminum meter, cut
                   1/16-inch off each post of the ERT wriggler to prevent it from rubbing on the face of
                   the nut that holds the wriggler in place. If you are not installing on a 5B 225 meter,
                   continue to step 2 below.




                2. Set the wriggler to the desired position for mounting the ERT module assembly to the
                   meter.
                       •   For One-Foot Meters: Align the ERT module assembly wriggler with the
                           meter drive post (as shown below). Make sure the ERT wriggler is
                           perpendicular to the meter drive post.

                                                                                        Installation Prerequisites



                        •   For Two-Foot Meters: Align the ERT module assembly wriggler with the
                            meter drive slot (as shown below). It is acceptable for the pin on the 100G
                            wriggler to be installed inside or outside of the meter drive slot. For ease of
                            assembly, Itron recommends that the pin on the 100G wriggler be installed
                            outside of the meter drive slot.




                 3. Gently place the ERT module assembly on the meter. Align the four screw holes on
                    the ERT module assembly with the holes on the meter.

                4. Install and tighten all ERT module assembly mounting screws, working in a diagonal
                   pattern as shown below. Tighten the mounting screws to 15 to 20 inch-pounds of
                   torque. Use the 1/4 - 20 x 5/8-inch screws for this step (you can use the original
                   mounting screws if they were the correct size and not corroded; otherwise, use the
                   correct size Replacement Screws on page 6).

                6. Press the new tamper seals into place using the 11/32-inch nut driver (or another
                   similar blunt tool).




                7. Complete any necessary paperwork. Make sure no excess material is left on the
                   customer premises; dispose of it properly.
