*Itron recommends that these events be set to a disabled state in the Collection Engine's configuration settings as

they are primarily diagnostic and may strain the system in some cases. If disabled in the Collection Engine, these

events may still be retrieved via the diagnostic event log using field tools. Cellular Module Events

Tamper Alarms The OpenWay CENTRON ICM uses an accelerometer to detect motion in two planes.

Upon installation, reference readings for the X and Y axes are stored in the ICM. A

change in the X axis indicates an inversion tamper. A change in the Y axis indicates a

removal tamper. Any discrepancy triggers an alert to the Collection Engine unless

configured otherwise.

The OpenWay CENTRON ICM supports configurable meter tamper alarms for the

onboard Orientation/Shake Sensor (sampled every ten seconds from module startup). This

sensor has three functions:

• Counts the number of times the module has entered or exited the upright orientation

• Counts the number of times the module has been shaken

• Detects inverted installation (checked on module startup)

ERT Reads

To facilitate gas and water reads, the OpenWay CENTRON Cellular LTE ICM contains

an optional 900 MHz ERT reader to support Itron 100G DLS modules. The ERT reader

collects consumption data and tamper counts from 100G ERT modules and sends data to

the Collection Engine or other upstream systems.

The ICM records readings for up to 75 100G modules. Up to 15 100G modules are

supported in a Managed ERT configuration (see Managed ERT on page 12). All reads are

timestamped with UTC time. The ICM purges data older than the configured data lifetime

(the default is 31 hours).

ERT Data Retrieval Process The OpenWay CENTRON ICM with embedded ERT reader works with 100G modules,

the OpenWay CENTRON meter, and the OpenWay Collection Engine in the following

manner:

1. The ICM continuously listens for and records 100G meter reads.

2. The OpenWay Collection Engine communicates via cellular network to the ICM to

request a contingency, interrogation, or interactive read from the OpenWay

CENTRON meter.

3. The OpenWay CENTRON meter requests ERT data from the ICM, which responds

with the latest read for each 100G module.

4. This ERT data is returned via cellular network to the Collection Engine in response to

the read request.

5. The OpenWay Collection Engine performs de-duplication using the timestamp and

100G serial number.

6. ERT consumption data and tamper alarms are passed to the Itron Enterprise Edition

(IEE) MDMS via the DeviceComm interface.

ERT Reader Configurable Parameters The ERT reader supports the following configurable options:

• Utility ID. Configured during the manufacturing process according to meter

specification.



• Enable or Disable ERT. Indicates whether or not the ERT reader should be enabled

or disabled. This parameter is set during the meter configuration process.

Chapter 3 ERT Reads

Managed ERT The OpenWay Collection Engine (version 6.5 and higher) supports OpenWay CENTRON

Cellular LTE meters in Managed ERT mode, optimizing data flow over the network. Up

to 15 ERTs can be managed by a single electric meter. By contrast, unmanaged ERTs

depend on the Collection Engine to perform de-duplication between meters and ERTs.

With Managed ERT mode, the LTE meter supports a fixed ERT-to-meter relationship and

manages a certain number of ERTs for data collection and time synchronization. Each

ERT synchronizes its time with the electric meter once every 24 hours.

C H A P T E R

Power Outage Detection and Restoration

Power Outage The meter register notifies the ICM when power is lost. The ICM checks the

accelerometer for a tamper event, in which case a Removal Tamper exception is created.

If a tamper event is not detected, a Power Outage Notification is sent to the Collection

Engine via the cellular network. A bank of supercapacitors maintains power for up to 11

seconds, enabling the ICM to send either a Removal Tamper or Power Outage

notification.

A Power Outage notification includes the Meter ID and a unique Outage ID.

Power Restoration After power-up, the ICM will rejoin the network. Once the meter has synchronized to the

network, it sends a Power Restoration notification via a standard C12.22 message

structure. The Power Restoration notification includes the Meter ID and unique Outage

ID.

Meter Activation and Provisioning

Network Setup A private cellular network (APN) must be provisioned with the carrier prior to ordering

OpenWay CENTRON Cellular LTE meters. The APN must be upgraded to support LTE

communications. In addition, utility network firewalls must allow User Datagram

Protocol (UDP) traffic flow over the cellular network. OpenWay CENTRON Cellular

LTE meters communicate using UDP, as do other OpenWay meter types.

For the Verizon network, the LTE inactivity timer should be set for 16 hours to optimize

communications and network traffic with the meter. During the manufacturing process, it

is required that customers provide Itron with the inactivity timer duration if it is not set to

the recommended 16 hours. Please ensure that this information is properly provided

during the specification process.

Activating a Cellular Meter In order for a meter to communicate via cellular network, it must be activated. If the

meter is already activated on the cellular network, skip this section and go to Provisioning

the Meter in the OpenWay Collection Engine (to set up the meter profile in the Collection

Engine).

Important Once a meter has been activated, the customer is responsible for

all airtime charges. Customers must request meter deactivations and will be

billed for airtime charges until deactivation occurs.
