PG421005A A3 ALPHA Meter/Collector
July 2003 9
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. Table 2 identifies the ILC1 option board error
conditions and the associated display quantity value. The quantity identifier is the
same for all ILC1 option board error codes and can be any numeric character
(represented by i in Table 2).
Condition Quantity identifier Display quantity value
No error iii 000000
Clock error iii 000001
Carryover error iii 000010
Table CRC error iii 000100
Configuration error iii 001000
Shared memory error iii 010000
Power fail data save error iii 100000
Table 2. Error conditions and codes
Error codes may be displayed in combination (for example, iii-100001) indicating
that more than one error condition has been detected.
No error. This code is displayed when no error condition exists in the ILC1 option
board. Since ILC1 option board error codes must be programmed as display
items, the no error code is used when no error condition is present in the ILC1
option board.
Clock error. This code indicates an error with the timekeeping ability of the ILC1
option board. The ILC1 option board can lose its real time clock if the A3 ALPHA
meter has lost its timekeeping capability or if the ILC1 option board cannot
communicate with the A3 ALPHA meter. When this condition is present, all REX
meters in the network revert to relative timekeeping and store all energy data in
the default rate.
Replace the meter battery. The ILC1 option board periodically attempts to read
time from the A3 ALPHA meter (the ILC1 option board reads the time every 15
minutes by default). The ILC1 error will clear after the ILC1 successfully communi-
cates to the A3 ALPHA meter and reads a valid time. The error code should be
cleared within 15 minutes of the time the battery is replaced. If the error code
continues to be displayed, return the A3 ALPHA meter with ILC1 option board to
Elster Electricity for repair or replacement.
Carryover error. This code indicates that the ILC1 option board's battery-backed
RAM was not maintained during a power failure. When there is a power failure,
battery-backed RAM on the ILC1 option board is maintained by the A3 ALPHA
meter's super capacitor or battery. If both of these fail, the data stored in RAM is
lost. The meter battery may need to be replaced. The ILC1 option board error will
be cleared remotely by the MAS.
Table CRC error. This code indicates a possible error in the ILC1 option board's
