Chapter 2 American Meter Installation 16 2.4GZ OpenWay Gas Module Installation Guide 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 2.4GZ OpenWay Gas Module Installation Guide 17 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. 12 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.
Chapter 2 American Meter Installation 18 2.4GZ OpenWay Gas Module Installation Guide 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.
