programming. This error may be corrected remotely by the MAS. If the error code
is displayed after reprogramming, return the A3 ALPHA meter with ILC1 option
board to Elster Electricity for repair or replacement.
General configuration error. This code indicates a problem with the ILC1 option
board's configuration or program. The error may be corrected remotely by the
MAS. Contact Elster Electricity if this error code continues to be displayed on the
LCD.
Shared memory error. This code indicates that one of the following conditions
has occurred:
■ The amount of memory requested by the ILC1 program exceeds the amount
of physical memory present.
■ The shared memory configuration has been changed and a clear data
command has not been performed.
Shared memory on the ILC1 option board is used to allow the number of regis-
tered meters and the number of meters for which the ILC1 option board stores
profile data to be varied to meet specific applications. The ILC1 option board will
support a maximum of 1024 registered nodes. The amount of memory required
to store current billing data, previous period billing data, and previous season
data limits the amount of data available for storage of load profile data. There are
two variables that control the amount of shared memory required to store load
profile data:
■ The number of REX meters for which load profile data is to be stored.
■ The number of days of data to store for each REX meter.
As these two load profile variables are increased, the maximum number of
registered nodes must be decreased to allow all of the data to fit within the
available shared memory on the ILC1 option board.
If a shared memory error exists, it can be corrected remotely by the MAS.
Contact Elster Electricity if this error code continues to be displayed on the LCD.
Power fail data save error. This code indicates that the data saved in the ILC1
option board's nonvolatile memory during a power fail may be invalid. This error
will be displayed when power is restored to the meter if a self check has discov-
ered an error with the ILC1 option board's memory. This error can be corrected
remotely by the MAS.
ILC1 Option Board Status Codes
For ILC1 status codes to appear on the A3 ALPHA LCD they must be pro-
grammed as displayable items. Status codes indicate the operational status of
the ILC1 option board. Unlike error codes, the status codes do not indicate a
problem with the ILC1 option board. Table 3 identifies the status condition and its
associated display quantity value. The quantity identifier is represented by i in
Table 3.
