• reverse flow (encoder version selected)
• system leak status
• low battery indicator
In OpenWay Riva Network Mode, the module reports four interrogation cycles daily. Each
interrogation collects six hours of interval and event data.
Note: Interval data functionality is dependent on the module's firmware version. For more
information, see OpenWay Riva Water module firmware functionality on page 8.
The OpenWay Riva water module also sends a local access beacon message every 60
seconds that allows users to gather contingency readings locally when needed.
Caution: If you perform a Switch to OpenWay Riva Network Mode or Switch to
Mobile Mode operation, it results in a loss of interval data.
The OpenWay Riva water module operates using the 902 to 928 MHz in the ISM band
frequency band and does not require an FCC license.
OpenWay Riva pit module operating modes
The OpenWay Riva pit module has the following operating modes.
1. Factory Mode
• Pit modules ship from the factory in Factory Mode.
• The pit module's transmitter is off.
• The pit module's receiver listens for a programming command.
• The pit modules attempt to read the register every hour.
• Last Good Read and Extended event or alarm flags may be set when a register is not
connected.
• If the pit module reads a connected register, the pit module automatically switches to
Run Mode.
2. Audit Mode
• Audit mode reduces the normal read latency time associated with standard modes of
operation and is often used after initial installation.
• This mode is useful in Riva network installations where the normal bubble rate is very
slow.
• Audit Mode remains active for 30 days and then reverts to the initial programmed
mode.
• Audit Mode is intended to be used once.
3. Run Mode
• Pit module normal operation mode.
• The OpenWay Riva Water Pit Module transmitted message is dependent on its factory
settings or setting programmed with FDM for standard consumption messages (SCM
+). For SCM+ (Mobile), the pit module default bubble-up rate is 10 seconds.
