However, if the A3 ALPHA meter is enclosed in a meter service cabinet or the antenna must be mounted higher to overcome signal obstruction, an external antenna may be used.This leaflet contains general information for installing the A3 ALPHA meter equipped with connections for an external antenna.■For information on the operation of the A3 ALPHA meter, see the A3 ALPHA Meter Technical Manual (TM42-2190B or later) or the A3 ALPHA Meter Technical Manual For Use in Canada (TM42-2195A or later)■For information on installing the A3 ALPHA meter, see the “ALPHA Meter Installation Instructions” (IL42-4001Q or later)WARNING!Use authorized utility procedures to install and service metering equipment. Dangerous voltages are present. Equipment damage, personal injury, or death can result if safety precautions are not followed.Use circuit closing devices on current transformer secondaries (3S, 4S, 5S, 5A, 6S, 6A, 8S, 9S, 10S, 10A, 26S, 29S, 35S, 35A, 36S, and 36A meters). Equipment damage, personal injury, or death can result if circuit closing secondaries are not used.Connecting an External AntennaNote. This device has been designed to operate with the antennas listed below and having a maximum gain of 5.15 dBi. Antennas not included in this list or having a gain greater than 5.15 dBi are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.Internal antenna: Elster Electricity P/N: 1B12150H01Local external antennas: Laird/Antenex TRA(B)9023P1 (3.1 dBi); Laird/Antenex TRA(B)9023NP (3.1 dBi)Remote external antennas: PCTEL/MAXRAD P/N MFB9150 (Tessco P/N 39493) for unity gain (2.15 dBi); PCTEL/MAXRAD P/N MFB 9153 for 3 dB gain (5.15 dBi)The external antenna connects to the ILC2 option board using a connector lead as shown in Figure 1. In addition to the standard internal antenna, there are two options available for connecting an external antenna:■Local external antenna■Remote external antenna1Part number specifies an antenna with a black body. For an antenna with a white body, use part number TRA9023P.Preliminary
IL42-4032A June 20082Figure 1. Retaining clip and connector leadLocal External AntennaIf the A3 ALPHA meter is used in a metal service cabinet, using a local external antenna may be necessary. To obtain better coverage, the local external antenna can be mounted on the top of the metal service cabinet or the meter socket enclosure (see [1] in Figure 2).Elster recommends Antenex Inc.’s 902-928 MHz Permanent Mount antenna (TRAB9023P).1 To mount the antenna on the service cabinet or meter socket enclosure, drill a 5/8-inch hole into the cabinet wall with a step drill. Insert the antenna through the hole. After the antenna is mounted, the antenna’s Type N female connector can be mated with the meter’s Type N male connector.For installations where the mounting for the local antenna does not provide a conductive metallic ground plane, the Antenex TRAB9023NP (no ground plane required) may be employed. The gain and pattern are virtually identical with the TRAB9023P version and the TRAB9023NP may also be employed on metallic ground planes with good results.Remote External AntennaIf the A3 ALPHA meter is used in a metal building, or the meter is installed in a location where the site requires an antenna at a greater height to overcome blocked signals, a remote antenna may be required. If a remote external antenna is used, a lightning/surge arrestor should be installed at the bottom of the socket enclosure (see [2] in Figure 2). Elster recommends a PolyPhaser DSXL IN-LINE EMP surge filter (Tessco P/N 491574).2NOTICEDo not use a standard RG-8/U cable with solid polyethylene dielectric. The losses in solid dielectric RG-8/U cables in short distances make solid dielectric RG-8/U cables unacceptable.The most economical connection to the remote external antenna is the RG-8/U “foam” or “LMR-400” type cable. This type of cable should be suitable for distances of up to 100 feet. The foam dielectric cable will incur a loss of approximately 3.9 dB in 100 feet (or approximately 2 dB in 50 feet). The coaxial cable should be mounted at the bottom of the meter socket in “drip loop” fashion. A “drip loop” is formed by bringing the coaxial cable to a point below the meter socket and then bending it back up to the connector. This forms a U-shape, which allows water to run down the cable exterior. Antenna cables should be ordered with N-type male connectors on each end.1Antenex, 2000-205 Bloomingdale Road, Glendale Heights IL 60131. Telephone: 630-351-9007.

June 2008 IL42-4032A3The collectors and nodes in the EnergyAxis System operate under Part 15.247 of the FCC Rules. Suitable antennas are omni-directional antennas of unity gain or 3 dB gain (2.15 and 5.15 dBi, respectively). Elster recommends the following, which are rated to withstand 100 mph winds and are fitted with Type N female connectors:■PCTEL/MAXRAD MFB9150 Series (Tessco P/N 39493) for unity gain (2.15 dBi)■PCTEL/MAXRAD MFB9153 Series (Tessco P/N 74330) for 3 dB gain (5.15 dBi)Regardless of the antenna selected, the antenna should be mounted with at least two MMK1 pipe clamps (Tessco SKU 68869). The antenna should be mounted in the clear, as free from the conductive or metallic obstructions as possible. The connectors should be sealed for waterproofing.Figure 2.

A3 ALPHA Meter/Node (ILC2)Product Guide June 2008iiDRAFT
A3 ALPHA Meter/Node (ILC2)June 2008 Product Guide1General Description The A3 ALPHA meter can be used as a component of the EnergyAxis® System where remote communications in polyphase and advanced single phase meter-ing is desired for commercial and industrial accounts. The A3 ALPHA meter can be equipped with an option board that communicates to the network via the 2-way, 900 MHz, radio frequency LAN. This option essentially allows the A3 ALPHA meter to be a metering node within the EnergyAxis automated metering network. The primary task of the ILC2 option board is to communicate within the local area network (LAN) and process billing data from A3 ALPHA meters. The A3 ALPHA meter performs its programmed metering tasks but now has remote communications features within the EnergyAxis network.In addition with the other communication functions as part of the EnergyAxis System, the A3 ALPHA meter/node can return metering data in one of the fol-lowing formats:■The short data format provides kWh consumption data, three current maximum demand quantities, one channel of load profiling, and basic status information.■The long data format provides two metered quantities, two maximum or coincident demands, two channels of load profiling, and extensive sta-tus information.The format is selected at the time of ordering and is configured at the factory. The short data format can be used when only one metered quantity or one load profiling channel is needed. The long data format can be used if you need two metered quantities, two load profiling channels, or other data not provided by the short data format. The long data format requires more communication time and more storage in the collector. For more information about the two data for-mats, including the status information they return, see “ILC2 Option Board Con-figuration” on page 5.A3 ALPHA Meter Circuit BoardThe A3 ALPHA meter builds upon the strengths of the existing ALPHA meter designs. Like its predecessors, the A3 ALPHA meter uses Elster Electricity’s patented digital measurement techniques that offer high accuracy, repeatability, and low ownership costs. In support of open architecture standards, the A3 ALPHA meter is the first Elster Electricity meter to fully support ANSI C12.18, C12.19, and C12.21 standards.To function as a node in the EnergyAxis System, an A3 ALPHA meter requires the following option boards:■internal interface board to support the mounting of the ILC2 option board■the ILC2 option boardThe interface board connects to the A3 ALPHA meter using the 20-pin header (J4) on the meter circuit board as shown in Figure 1. The ILC2 option board con-nects to the interface board using the 20-pin header (J5) as shown in A3 ALPHA meter electronic assembly.The antenna for the ILC2 option board mounts directly onto the electronic hous-ing (see Figure 2) and fits completely under the cover of the A3 ALPHA meter.A thin shield between the interface board and the main meter circuit board pro-vides additional isolation between the option boards and the high voltage com-ponents of the A3 ALPHA meter. The unit should not be operated without this shield installed.DRAFT

A3 ALPHA Meter/Node (ILC2)June 2008 Product Guide3Metercat Programming NoteTo have the A3 ALPHA meter function properly as a node in the EnergyAxis Sys-tem, it is important that the meter be programmed correctly using Metercat™. Be sure to understand the following restrictions:Component DescriptionQuantities ■Short data format: The ILC2 will return the first kWh quantity configured in the meter.■Long data format: The ILC2 will return the first two quantities configured in the meter. It will also return the first two coincident demands configured in the meter.Interval Data Configuration ■Quantities to Record: The first two quantities will be the quantities profiled by the node. Selecting any net quantity will result in an ILC2 configuration error.■Interval Length: If using short data format, select only 15, 30, or 60 minutes. If using long data format, select any value evenly divisible into 60 (that is1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, or 60). Selecting any other interval length will return interval data, but with an unknown interval length reported to MAS. Display When operating as a node, the following items (located in the LAN Items category) are available for display:■ILC errors■ILC status■LAN ID■utility ID■LAN registration informationDemand Interval (minutes): If using short format, Elster recommends that you select 15, 30, or 60 min-utes. If using long format, you may select any value evenly divisible into 60. Selecting any other value will prevent the actual demand interval length from being reported in the data. That is, the actual data will be reported without specify-ing the demand interval length.Special Dates When instructing the meter to perform a demand reset for either recurring or nonrecurring dates, any demand reset date will be cleared by the ILC2 option board (except those assigned to a season change date). Within the EnergyAxis System, billing demand resets are controlled by the system through the collector.Remote1Configure port 1 usage for “Direct Connect” and port 2 usage for “Disabled.”Port 1 direct connect should be set to 9600 bps.DRAFT
A3 ALPHA Meter/Node (ILC2)Product Guide June 20084Note. If the remote definition is not programmed into the meter, the ILC2 will not be able to return any meter reads to MAS.The other options can be set as desired. For more information on using Meter-cat, see the Metercat user guide (TM42-2203K or later) or the online Help.Metering Software and SystemMetercatThe A3 ALPHA meter operating as a node in the EnergyAxis System requires Elster Electricity Metercat support software release 1.8 or later. Metercat offers the following features:■program development to create user-defined configuration data■meter programming to send user-defined configuration data or com-mands to the meter■meter reading to receive data that has been stored by the meter■diagnostic read including ILC2 option board and LAN statusEnergyAxis Metering Automation ServerThe EnergyAxis Metering Automation Server (MAS) reads meters over telephone or wireless networks. Using MAS, meter readings can be scheduled or per-formed on-request from the browser-based user interface. MAS allows all billing data to be read from the meter; this includes data from each A3 ALPHA meter registered with the EnergyAxis local area collector. Billing data from the A3 ALPHA meter includes consumption, demand, time-of-use registers as well as meter status flags. The A3 ALPHA meter data can be read from the stored data in the collector or on-request by using MAS to communicate through the collector to the individual A3 ALPHA meter.Data exchange between MAS and other utility systems is performed using an open XML schema, AMR Data Exchange Format (AMRDEF), so that interfaces with billing systems and other enterprise systems can be easily implemented. MAS also comes with the JSlinger module, a powerful driver for file transfer pro-tocol (FTP) that can transform, compress and encrypt data files prior to sending them to trusted IP addresses across the Internet.Operation of the A3 ALPHA Meter with ILC2 Option BoardThe A3 ALPHA meter and the ILC2 option board communicate within the Ener-gyAxis system 900 MHz radio frequency network. The primary task of the ILC2 option board is to communicate with the LAN and to provide meter readings from the A3 ALPHA meter and pass on commands to the A3 ALPHA meter. While the time base within the A3 ALPHA meter is maintained by its super capacitor and a battery, time is adjusted automatically by the network when required.Billing DateThe EnergyAxis System handles the billing dates for the registered A3 ALPHA meters. MAS assigns each meter to one of 30 possible billing dates, and then MAS transmits the billing dates to the meters' respective collectors. On the bill-ing date, the collector schedules the meter to perform a demand reset at the next midnight crossing.1If you do not see the Remote tab, select Remote as a program option in the Properties tab of your program.DRAFT
A3 ALPHA Meter/Node (ILC2)June 2008 Product Guide5At midnight, the ILC2 option board copies the A3 ALPHA meter's billing data to a separate memory location. A demand reset is then performed immediately thereafter. During the next reading of all its registered meters, the collector retrieves and stores the copy of the billing data. Once the billing data is stored in the collector, it can be retrieved by MAS at the next read of the collector.This feature allows individual meters to be identified to a specific billing date that conforms to the consumer's request or the utility's business process. Neighbor-ing meters can have individual billing dates and are not forced to be read on the same day. Changes to the billing date are handled through a schedule change in MAS.TOU SchedulesThe A3 ALPHA meter can be programmed using Metercat to operate on a TOU program. Each program includes a TOU schedule and display list. Each TOU schedule for the A3 ALPHA meter consists of weekday, weekend, and two spe-cial day types (that is, holidays). The display list controls the values that are shown on the A3 ALPHA meter LCD. See the A3 ALPHA Meter Technical Man-ual (TM42-2190) for information on the values that can be displayed on the A3 ALPHA meter LCD.Season ChangesSeason changes for the A3 ALPHA meter are controlled by the calendar in the A3 ALPHA meter.Power Failure and RestorationWhen there is a power failure, the A3 ALPHA meter initiates a shutdown and stores the A3 ALPHA meter billing data and status information in EEPROM. All information stored in the ILC2 option board is stored in battery-backed RAM. The A3 ALPHA meter’s real-time clock and the data stored in the ILC2 option board are maintained by the super capacitor and battery in the A3 ALPHA meter during a power failure. If both the super capacitor and battery fail, all RAM in the meter and in the ILC2 will be lost.Upon subsequent power restoration, an error code is generated for both the A3 ALPHA meter and the ILC2 option board.■For information on A3 ALPHA meter error codes, see the A3 ALPHA Meter Technical Manual (TM42-2190).■For information on ILC2 option board error codes, see “ILC2 Option Board Error Codes” on page 7.ILC2 Option Board ConfigurationAt the time of ordering, the node can be configured to report register data in one of two ways:■short data format■long data formatShort data format. The short data format returns the first kWh consumption data configured in the meter, three current maximum demand quantities, identi-fication for 1 channel of load profiling, and 1 channel of load profiling to the col-lector.■The first demand quantity can be assigned to the maximum demand of any of the four tiers or can be assigned to the total demand.DRAFT
A3 ALPHA Meter/Node (ILC2)Product Guide June 20086■The second demand quantity can be assigned to any of the four rates.■The third demand quantity can be assigned to any of the four rates.In addition, the short data format returns the following information:■per phase voltages■A3 ALPHA meter configuration information■the presence of meter error or warning codes■number of demand resets■number of outagesLong data format. The long data format returns the first two metered quanti-ties configured in the meter, maximum demand or cumulative maximum demand for all rates, identification for 2 channels of load profiling, and 2 chan-nels of load profiling to the collector.In addition, the long data format returns the following information:■per phase voltages■A3 ALPHA meter configuration■specific meter error or warning code■number of demand resets■number of outagesReading the A3 ALPHA MeterThe A3 ALPHA meter can be read in the following ways:■visually using the LCD■optically using Metercat support software■remotely via the EnergyAxis system 900 MHz networkFor more details on the information that can be viewed on the LCD, see “Display List Items” on page 7.For more details on reading the A3 ALPHA meter optically, see the Metercat documentation and online Help.For more details on reading the A3 ALPHA meter remotely, see the MAS docu-mentation and online Help.Changing an A3 ALPHA Meter Use authorized utility procedures to remove metering equipment. Dangerous voltages are present. Equipment damage, personal injury, or death can result if safety procedures are not followed.If the A3 ALPHA meter must be taken out of service (because of an error condi-tion, the ILC2 option board fails, etc.), the A3 ALPHA meter can be replaced with another A3 ALPHA meter. See the change-out information in the A3 ALPHA Meter Technical Manual (TM32-2190)DRAFT
A3 ALPHA Meter/Node (ILC2)June 2008 Product Guide7Display List Items The A3 ALPHA meter display is divided into different regions as shown in Figure 3. See Chapter 3, “Operating Instructions,” in the A3 ALPHA Meter Technical Manual (TM42-2190) for more detailed descriptions of the LCD and its display regions.Figure 3. A3 ALPHA meter LCDThe display list for all displayable items, including the items relating to the ILC2 option board, can be programmed using Metercat meter support software.ILC2 Option Board Error CodesUnlike standard A3 ALPHA meter error codes, ILC2 option board error codes must be programmed as a displayable item in the A3 ALPHA meter display list using Metercat support software; otherwise, the meter LCD will not display any indication that a condition exists that affects the ILC2 option board's operation. Error conditions and codes identify the ILC2 option board error conditions and the associated display quantity value. The quantity identifier is the same for all ILC2 option board error codes and can be programmed to be any numeric char-acter (represented by i in Table 1).Table 1. Error conditions and codesError codes may be displayed in combination (for example, iii 100100), indicat-ing that more than one error condition has been detected.No error. This code is displayed when no error condition exists in the ILC2 option board. Since ILC2 option board error codes must be programmed as dis-play items, this code is used when no error condition is present in the ILC2 option board.ARhCUMKWRATETOTALRESETSCONTMAXABCDPREV SEASTESTALT EOIQuantity identifer Display quantityPotentialindicatorsEnd of intervalindicatorReal energyindicators Alternate energyindicatorsPower/energyunits identifierDisplay identifersOperating modeindicatorsCondition Quantity identifier Display quantity valueNo error iii 000000Table CRC error iii 000100Configuration error iii 001000Shared memory error iii 010000Power fail data save error iii 100000DRAFT

This code indicates a problem with the ILC2 option board’s configuration or program.■If the node is programmed for the short data format, verify that the meter is programmed with at least one kWh quantity.■If the meter is programmed for load profiling, this error code will be dis-played if one of the first two quantities is programmed for a net quantity.Contact Elster Electricity if this error code is displayed and there is no apparent programming issues.Shared memory error. This code indicates a problem exists in the shared memory area. Contact Elster Electricity if this error code is displayed on the LCD.Power fail data save error. This code indicates that the data saved in the ILC2 option board’s nonvolatile memory during a power failure may be invalid. This error will be displayed when power is restored to the meter if a self check has discovered an error with the ILC2 option board’s memory. Contact Elster Electricity if this error code continues to be displayed on the LCD.ILC2 Option Board Status CodesILC2 status code must be programmed as a displayable item to appear on the A3 ALPHA meter LCD using Metercat support software. Unlike error codes, the status codes do not indicate a problem with the ILC2 option board. Status con-dition and code identifies the status condition and its associated display quantity value. The quantity identifier is the same for all ILC2 option board status codes and can be programmed to be any numeric character (represented by i in Tab l e 2 ).Table 2. Status conditions and codesNo status. This code is displayed when no status condition exists in the ILC2 option board. Since ILC2 option board error codes must be programmed as dis-play items, this code is used when no status condition is present in the ILC2 option board.Node is registered. This code indicates that the A3 ALPHA meter with the ILC2 option board is registered with a collector. See “Network registration sta-tus” on page 9 for more specific information about the registration information.Demand reset scheduled. This code indicates that the meter has been scheduled to perform a demand reset at the next midnight crossing. This code is displayed when the node receives a command to perform a demand reset from the network. The code remains in the display until the next midnight cross-ing (the time at which the meter performs a demand reset). See the A3 ALPHA Meter Technical Manual for more information on demand resets.Condition Quantity identifier Display quantity valueNo status iii 000000Node is registered iii 000100Demand reset scheduled iii 000010DRAFT
