A3 ALPHA® Meter/Collector Product Guide PG42-1005A
A3 ALPHA Meter/Collector PG42-1005A General Description The A3 ALPHA meter/collector is the communications point between the EnergyAxis System and the local network of REX meters that are registered to the meter/collector. The EnergyAxis System communicates with the A3 ALPHA meter/collector using a standard telephone line. The A3 ALPHA meter/collector then communicates with its registered REX meters using a 2–way, 900 MHz radio frequency network.

A3 ALPHA Meter/Collector PG42-1005A Metercat Programming Note To have the A3 ALPHA meter function properly as a data collector in the EnergyAxis System, it is important that the meter be programmed correctly using Metercat. In the Remote component tab in Metercat, be sure that the following options are set: ■ Port 1 usage is set to internal modem. ■ Port 2 usage is set to direct connect. ■ On the Port 1 Modem tab, enable line sharing (the Enable Line Sharing box is checked).
PG421005A Operation of the A3 ALPHA Meter with ILC1 Option Board A3 ALPHA Meter/Collector The A3 ALPHA meter and the ILC1 option board typically operate independently of each other. The primary task of the ILC1 option board is to maintain the local area network (LAN) and read and store billing data from REX meters. The ILC1 option board communicates with the A3 ALPHA meter/collector to read time and day type information. This information is then propagated through the LAN to the REX meters.
A3 ALPHA Meter/Collector PG42-1005A Call Initiation The A3 ALPHA meter/collector can initiate billing, alarm, and outage/restoration calls based on the customer program configured in the meter.
PG421005A Reading the A3 ALPHA Meter/Collector A3 ALPHA Meter/Collector The A3 ALPHA meter/collector can be read in the following ways: ■ visually using the LCD ■ remotely using the ITM3 option board and Elster Electricity meter support software For more details on the information that can be read on the LCD, see "Display List Items." Using the telephone modem, Table 1 shows the information that can be obtained from the A3 ALPHA meter/collector. Table 1.
A3 ALPHA Meter/Collector Changing an A3 ALPHA Meter with ILC1 Option Board PG42-1005A WARNING ! 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/collector must be taken out of service (because of an error condition, the telephone modem fails, etc.), the A3 ALPHA meter/collector can be replaced with another A3 ALPHA meter/collector.
PG421005A A3 ALPHA Meter/Collector The display format for all displayable items, including the items relating to the ILC1 option board, can be programmed using Elster Electricity meter support software. ILC1 Option Board Error Codes Unlike A3 ALPHA meter error codes, ILC1 option board error codes must be programmed as displayable items in the A3 ALPHA meter display list; otherwise, the meter LCD will not display any indication that a condition exists that affects the ILC1 option board's operation.
