Troubleshooting
Typically, meters are placed in a very unfriendly environment. While the CENTRON
Polyphase meter is designed to perform within this harsh environment, things can go wrong
with the meter or installation.
Fatal Errors
Fatal errors cause the display to lock on the error code because of the possibility that billing
data may have been corrupted or that the meter may not be operating correctly. If multiple
fatal errors occur, the one with the lowest number will be the error code that locks on the
display.
The CENTRON Polyphase meter will check for fatal errors:
when a meter reconfigure is performed.
when power is initially energized and upon future power restoration.
while performing key operations.
The different fatal errors should be handled as described in the table below. Fatal errors can
only be cleared by performing a Factory Reset on the meter will wipe out all information in
the meter, so be sure to try to retrieve any meaningful data from the meter prior to
performing the Factory Reset. After this is performed, the meter must be reprogrammed.
Sometimes when a battery is plugged into a meter while the meter is powered
down, it will result in a fatal error when the meter is powered up. This is due to
an unstable voltage on the battery. In this case, the fatal error can be ignored and
a Factory Reset performed on the meter. To prevent these fatal errors from
occurring, always power up the meter before plugging a battery into it.
