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).

WARNING! Failure to place the drive post into the drive slot can cause binding

and lead to poor registration or meter failure

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.

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.

Installing the 2.4GZ OpenWay Gas Module

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.

To Program the OpenWay Gas Module

1. Make sure the 2.4GZ OpenWay Gas Module is within 10 feet of the programming

device.

2. Verify that the programming software is running.

3. Verify that red LED on ZigBee dongle is on.

4. Hold the magnet under the 2.4GZ OpenWay Gas Module for 5 seconds and then

remove it. You will see three red blinks from the LED. This signifies that the 2.4GZ
OpenWay Gas Module is searching for a programming device. Within a few seconds
the red LED will blink five more times. The programming device will indicate
programming success or failure.

a) If five red LED blinks are not seen on the 2.4GZ OpenWay Gas Module, hold the

magnet under 2.4GZ OpenWay Gas Module for 5 seconds.

b) If 5 red LED blinks are seen on the 2.4GZ OpenWay Gas Module, but the

programming device indicates that programming failed, verify the following (1)

2.4GZ is within 10 foot range of programming device and (2) programming
software is using correct security key. Repeat holding magnet under 2.4GZ for 5
seconds.

When the 2.4GZ OpenWay Gas Module has been programmed to normal mode, it is ready
to commission to an OpenWay CENTRON meter. If an OpenWay CENTRON meter is
within range of the 2.4GZ OpenWay Gas Module, the red LED on the 2.4GZ OpenWay Gas
Module will blink three times, indicating that it is looking for all available OpenWay
CENTRON meters.

After choosing the OpenWay CENTRON meter with the best signal, the 2.4GZ OpenWay
Gas Module will blink five times to indicate successful commissioning to the meter. The
timing for this could be as quick as one second after being programmed. If within two
minutes of successful programming, the five blinks are not seen, make note of the
installation for further investigation.

NOTE Itron will be moving to this programming solution in 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.

Attach the OpenWay Gas Module to the Meter

After the 2.4GZ OpenWay Gas Module has been programmed and is reading correctly,
follow the steps below to attach it to the meter.

To attach the 2.4GZ 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.
