Figure 5-1. Sample error code displayed on the LCD
Table 5-1. Error conditions and codes
E00000: ROM checksum error. This code indicates a problem with the meter’s
program. If this code is displayed on the LCD, the REX meter should be returned
to the factory for repair or replacement.
E00001: improper meter engine error. This code indicates that the meter
engine program may be corrupt or is not executing correctly. This error condition
is typically triggered when the microcontroller fails to reinitialize the meter engine.
If the code is displayed on the LCD, the REX meter should be returned to the
factory for repair or replacement.
E00010: EEPROM write error. This code indicates the meter had a problem
storing meter data in its nonvolatile EEPROM. The REX meter should be
returned to the factory for repair or replacement.
E00100: table CRC error. This code indicates a possible error in the REX
meter’s programming. Depending on which area of the meter is affected, billing
data may not be reliably accumulated while this error condition exists. The REX
meter should be returned to the factory for repair or replacement.
E01000: configuration error. This code indicates a problem with the meter’s
configuration. If the error continues after reprogramming, the meter should be
returned to the factory for repair or replacement.
E10000: power fail data save error. This code indicates that the data saved in
nonvolatile EEPROM during a power failure may be invalid. This error will be
displayed when power is restored to the meter, and a self check has discovered
an error with the EEPROM data after a power fail data save. The REX meter
should be returned to the factory for repair or replacement.
