Extended Alarm Flag
This is retrievable with two-way communication.
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.
Register Error Detected
■
Register Error Detected indicates that the OpenWay Riva remote 500W ERT module is not
communicating with the register/meter. The event or alarm flag automatically clears after the
500W ERT 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 500W ERT module . The low battery warning 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 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: OpenWay Riva 500W ERT module events and alarms are dependent on the module's
firmware version. For more information, see Firmware Functionality.
The OpenWay Riva 500W ERT 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
500W ERT module . The extended alarms include:
■
