Register Error Detected
Register Error Detected indicates that the Cellular 500W remote module is not
communicating with the register/meter. The event or alarm flag automatically clears after the
Cellular 500W remote module receives a successful read from the register.
Note: The Register Error Detected flag may be an indicator of a damaged register.
Low Battery Warning
The OpenWay Riva remote 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 Cellular 500W remote module . The low battery warning allows the utility to easily
identify which Cellular 500W remote modules are nearing end-of-life in a mixed population
and gives the utility the opportunity to schedule replacement.
Note: The low battery warning 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.
For OpenWay Riva modules reporting in OpenWay Riva Network Mode.
Note: Cellular 500W remote module events and alarms are dependent on the module's
firmware version. For more information, see Firmware Functionality on page 13.
The Cellular 500W remote module reports the tampers available in Mobile Mode as well as
extended meter alarms available from new solid-state and electronic meters connected to the
Cellular 500W remote module . The extended alarms include:
Empty pipe
Temperature
High flow
Meter low battery

For more information about the extended alarms, see the OpenWay Riva Collection Manager
