CHAPTER 1 Getting Started The 100G is Itron's latest high-powered gas encoder-receiver-transmitter (ERT) module. ERTs are meter-installed devices that transmit meter data using radio communications. That information may be received by a reading device that is within transmission distance, meaning that multiple devices may receive data from a single endpoint. Itron's 100G ERT is a high-powered device with a wide 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 two standard available transmission modes: • Fixed Network Mode In this mode, a 100G ERT module transmits a high-powered RF message every 60 seconds. • Mobile and HandHeld Mode In this mode, a 100G ERT module transmits a medium-powered RF message every 15 seconds. An FCC license is not required to read 100G ERT modules. Specifications The functional and operational specifications for the 100G are listed below.

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. • Use 1/4 - 20 x 5/8-inch slotted, Fillister head screws for mounting 100G ERT module assemblies on meters. • Use 8 - 32 x 3/16-inch slotted, round head screws for mounting indexes on 100G ERT module backplates. Preinstallation Preparations Before installing the 100G gas ERT module on a meter, verify that: • All ERTs are type 100G modules for American Meter Company gas meters. • The model numbers of all meters on which the 100G modules will be installed are included in the Meter Compatibility see "Meter Compatibility List" on page 2 list. Installing the 100G on an American Meter There are four major steps to installing the 100G gas ERT on an American Meter: • Remove the Existing Index • Assemble the ERT Module • Program the ERT Module • Attach the 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 American meter is to remove the existing index from the meter. To Remove the Existing Index 1. Remove any tamper seals from the meter. 6 100G Installation Guide
Installing the 100G on an American Meter 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. 100G Installation Guide 7
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. 12 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 athe ERT can be installed. 8 100G Installation Guide
Installing the 100G on an American Meter Assemble the ERT Module When installing a 100G gas ERT, the next major step is to create the ERT module assembly by combining the ERT 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 and index cover. 2. Separate the ERT module backplate from the cover. 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 idexes: • Index wrigglers on one-foot meters have drive slots. 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. 10 100G Installation Guide
Installing the 100G on an American Meter 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). 12 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 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). 21 100G Installation Guide 11
Chapter 2 American Meter Installation 7. Place the index mounting screw slot under the screw head. Do not tighten the screw yet. 8. Attach the wriggler to the index and backplate. • If the index wriggler has a drive slot (1), place the backplate wriggler's drive post (2) in the index wriggler's drive slot. 12 • If the index wriggler has a drive post (1), place the index wriggler's drive post in the backplate wriggler's drive slot (2). 12 12 100G Installation Guide
Installing the 100G on an American Meter 9. Install and tighten the left-hand index mounting screw (for indexes with either mounting screw slots or holes). 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). 10. Tighten the right-hand index mounting screw. 11. Slide the ERT cover (1) over the index and backplate, making sure the ERT label (2) is visible through the window. 1 2 Next, program the ERT module. Program the ERT Module Once the ERT module has been assembled, the ERT must be programmed using the FC200/SR with EndPoint-Link software. See the EndPoint-Link ERT Programming Guide (TDC-tbd-xxx) for more information. IMPORTANT You must perform the following programming procedure for the ERT module to function properly. 100G Installation Guide 13
Chapter 2 American Meter Installation 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. Be sure to program the ERT based on the indicated drive rate. 12 To Program the ERT Module 1. Using the FC200/SR, program the reading of the index that was on the meter into the ERT module assembly. Be sure to hold the FC200/SR unit by the battery pack and within a few inches of the ERT during programming and reading; this will ensure proper communication between unit and the ERT. 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. 14 100G Installation Guide
Installing the 100G on an American Meter IMPORTANT Do not turn the drive wriggler faster than one turn per second. 1 2 3. Read the ERT module assembly using the FC200SR. Consult the EndPoint-Link ERT Programming Guide (TDC-tbd-tbd) 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 ERT 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. 1 2 100G Installation Guide 15
Chapter 2 American Meter Installation 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).
