• Register error detected. Register error detected indicates that the pit module is not
communicating with the register/meter. The event or alarm flag automatically clears after
the pit module receives a successful read from the register.
Note: The register error detected flag may be an indicator of a damaged register.
• Register error flag.
◦ The register error flag sets if the register error detected flag is active for 24 hours.
◦ The register error flag remains active for 40 days in mobile mode.
• Low battery indicator.
◦ The pit modules include a battery life estimator. The estimator is based on the number
of data packets sent at the various power levels and the age (self-discharge) of the pit
module.
◦ The low battery indicator allows the utility to easily identify which water modules are
nearing end-of-life in a mixed population and gives the utility the opportunity to
schedule replacement.
Note: The low battery indicator is a single flag that is set when the battery has less than
10% remaining capacity, which typically corresponds to 2 years of battery life remaining.
Battery life is evaluated daily at midnight.
