Installing the 2.4GZ OpenWay Gas Module There are four major steps to installing the 2.4GZ OpenWay Gas Module on a meter: • Remove the index • Assemble the 2.4GZ OpenWay Gas Module • Program the 2.4GZ OpenWay Gas Module • Attach the 2.4GZ OpenWay Gas Module to the meter. NOTE Properly dispose of all unused screws, old index covers, gaskets, tamper seals, and other left-over materials. Do not leave any materials on customer premises. Remove the Existing Index The first major step when installing a 2.4GZ OpenWay Gas Module on an American meter is to remove the existing index from the meter. To Remove the Index 1. Remove any tamper seals from the meter. 2.4GZ OpenWay Gas Module Installation Guide Installing the 2.4GZ OpenWay Gas Module 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-inches long and are not corroded. • If the screws are the correct length, and are not corroded, keep them for later use. • If the screws are an incorrect length or are corroded, dispose of them properly. Use the screws listed in Replacement Screws on page 7. 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. 2.4GZ OpenWay Gas Module Installation Guide Chapter 3 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. 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 7 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 OpenWay Gas Module can be installed. 10 2.4GZ OpenWay Gas Module Installation Guide Installing the 2.4GZ OpenWay Gas Module Assemble the OpenWay Gas Module When installing a 2.4GZ OpenWay Gas Module, the next major step is to create the OpenWay Gas Module assembly by combining the module backplate and cover with the meter index. Follow the procedure below to do so. To Assemble the OpenWay Gas Module 1. Obtain a new 2.4GZ OpenWay Gas Module. 2. Separate the module backplate (1) from the cover (2). 3. Set the new OpenWay Gas Module 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 index cover will be used later in this procedure. IMPORTANT Before continuing with the installation, note the following information about American Meter indexes: 2.4GZ OpenWay Gas Module Installation Guide 11 Chapter 3 American Meter Installation • Index wrigglers on one-foot meters have drive slots. • 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. 12 2.4GZ OpenWay Gas Module Installation Guide Installing the 2.4GZ OpenWay Gas Module 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 righthand 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 OpenWay Gas Module 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 OpenWay Gas Module 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). 2.4GZ OpenWay Gas Module Installation Guide 13 Chapter 3 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. 14 2.4GZ OpenWay Gas Module Installation Guide Installing the 2.4GZ OpenWay Gas Module • If the index wriggler has a drive post (1), place the index wriggler's drive post in the backplate wriggler's drive slot (2). 9. Install and tighten the left-hand index mounting screw (for indexes with either mounting screw slots or holes). 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). 10. Tighten the right-hand index mounting screw. 11. Slide the OpenWay Gas Module cover (1) over the index and backplate (2). Next, program the OpenWay Gas Module. 2.4GZ OpenWay Gas Module Installation Guide 15 Chapter 3 American Meter Installation Program the OpenWay Gas Module Once the OpenWay Gas Module has been assembled, the module must be programmed using FieldPro on a laptop with a ZigBee dongle. Refer to FieldPro documentation for programming information. IMPORTANT You must perform the following programming procedure for the OpenWay Gas Module to function properly. When programming the OpenWay Gas 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 OpenWay Gas Module based on the drive rate indicated on the index. 16 2.4GZ OpenWay Gas Module Installation Guide Installing the 2.4GZ OpenWay Gas Module To Program the OpenWay Gas Module NOTE Itron will be moving to this programming solution in early 2008 1. Using the FC200 and Belt Clip radio, program the reading of the index that was on the meter into the OpenWay Gas Module assembly. During programming, the OpenWay Gas 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 OpenWay Gas Module assembly can be read to the nearest cubic foot. 2. Slowly turn the OpenWay Gas Module drive wriggler two turns in the direction indicated on the index drive rate. This lets you verify the module is counting properly after assembly. IMPORTANT Do not turn the drive wriggler faster than one turn per second. 3. Read the OpenWay Gas Module assembly using the FC200 and Belt Clip radio. Consult the EndPoint-Link Programming Guide or other applicable instructions for details on how to read an OpenWay Gas Module. • If this reading is higher than the one you programmed in step 1 above, the module assembly is counting correctly. If the OpenWay Gas Module assembly reading is not higher than what was programmed in step 1, replace the module with a new one. 2.4GZ OpenWay Gas Module Installation Guide 17 Chapter 3 American Meter Installation Attach the OpenWay Gas Module to the Meter After the OpenWay Gas Module has been programmed and is reading correctly, follow the steps below to attach the module to the meter. To Attach the OpenWay Gas Module to the Meter 1. For 5B 225 Meters Only: If you are installing the OpenWay Gas Module on a 5B 225 aluminum meter, cut 1/16-inch off each post of the module 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 OpenWay Gas Module assembly to the meter. • 18 For One-Foot Meters: Align the OpenWay Gas Module assembly wriggler with the meter drive post (as shown below). Make sure the wriggler is perpendicular to the meter drive post. 2.4GZ OpenWay Gas Module Installation Guide Installing the 2.4GZ OpenWay Gas Module • For Two-Foot Meters: Align the OpenWay Gas Module assembly wriggler with the meter drive slot (as shown below). It is acceptable for the pin on the module wriggler to be installed inside or outside of the meter drive slot. For ease of assembly, Itron recommends that the pin on the OpenWay Gas Module wriggler be installed outside of the meter drive slot. 3. Gently place the OpenWay Gas Module assembly on the meter. Align the four screw holes on the module assembly with the holes on the meter. 2.4GZ OpenWay Gas Module Installation Guide 19 Chapter 3 American Meter Installation 4. Install and tighten all OpenWay Gas Module assembly mounting screws, working in a diagonal pattern as shown below. Tighten the mounting screws to 15 to 20 inchpounds 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 7). 5. Place a new tamper seal over two of the mounting screws as shown below. 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.

Using the FC200 and Belt Clip radio, program the reading of the index that was on the meter into the OpenWay Gas Module assembly. During programming, the OpenWay Gas 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 module assembly can be read to the nearest cubic foot. 2. Slowly turn the OpenWay Gas Module drive wriggler two turns in the direction indicated on the index drive rate. This lets you verify the module is counting properly after assembly. IMPORTANT Do not turn the drive wriggler faster than one turn per second. 3. Read the OpenWay Gas Module assembly using the FC200 and Belt Clip radio. Consult the EndPoint-Link Programming Guide or other applicable instructions for details on how to read an OpenWay Gas Module. • • If this reading is higher than the one you programmed in step 1 above, the ERT module assembly is counting correctly. If the OpenWay Gas Module assembly reading is not higher than what was programmed in step 1, replace the module with a new one. Attach the OpenWay Gas Module to the Meter After the OpenWay Gas Module has been programmed and is reading correctly, follow the steps below to attach the module to the meter. 2.4GZ OpenWay Gas Module Installation Guide 31 Chapter 5 Sensus Meter Installation To Attach the OpenWay Gas Module to the Meter 1.
