rate is not shown). Be sure to program the OpenWay Gas Module based on the drive rate
indicated on the index.
1
2
Installing the 2.4GZ OpenWay Gas Module
2.4GZ OpenWay Gas Module Installation Guide 17
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.
Chapter 3 American Meter Installation
18 2.4GZ OpenWay Gas Module Installation Guide
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.
• 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.
Installing the 2.4GZ OpenWay Gas Module
2.4GZ OpenWay Gas Module Installation Guide 19
• 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.

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 OpenWay Gas Module backplate from the cover.
3. Place the index drive gear (1) in the backplate wriggler gear cup (2) of the OpenWay
Gas Module (please note that the following example uses an 11-tooth drive gear; your
index may have a 16- or 18-tooth drive gear, and you must use the appropriate 2.4GZ
OpenWay Gas Module for your specific meter. See the Meter Compatibility list on
page 2 for more information).

Once properly in place, the index drive gear and backplate wriggler cup should look
similar to the following example.
4. Attach the right-hand mounting screw to the index and meter, just far enough to hold
the index in place. Use one 6 - 32 x 5/8-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 see "Replacement Screws" on page 25).

7. Slide the OpenWay Gas Module cover over the index and backplate.
8. Verify that the cover is installed correctly.
Once combined, the OpenWay Gas Module backplate, meter index, and OpenWay
Gas Module cover create an OpenWay Gas Module Assembly.
Next, program the OpenWay Gas Module.
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 Sensus meters. Sensus meters have a 2-foot drive rate, as indicated in the
example below (1), or a 0.05 cubic metre drive (not shown).

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 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.

To Attach the OpenWay Gas Module to the Meter
1. Gently place the OpenWay Gas Module assembly against the front of the meter as
shown. Make sure all four mounting screw holes in the 2.4GZ line up with the
corresponding holes on the meter.
2. Insert the top-right cover mounting screw. Tighten the screw just enough to hold the
2.4GZ in place. Use the 10 - 24 x 5/8-inch screws for this and the following step (you
can use the original mounting screws if they were the correct size and not corroded;
otherwise, use the correct size as described in Replacement Screws on page 25).
