-1666-000 OpenWay Riva Water Pit Module Installation Guide 3
Proprietary and Confidential
• 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 installations where the normal
bubble-up 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.
An FCC license is not required to read OpenWay Riva Water Pit Modules.
OpenWay Riva Water Pit Module 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 bubbles-up to listen for a programming command.
• pit modules attempt to read the register every hour.
• Last Good Read and Extended Tamper Flags may be set when a register is not connected.
• If the pit module reads a connected register, the pit module automatically moves to Run Mode.
2. 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.
3. Meter manufacturer quiet mode
• Meter manufacturers can configure the pit module for quiet mode after initializing and direct
mounting the pit module in the factory.
• The pit module awakens from quiet mode and enters run mode in one of two ways:
1. The pit module detects consumption at the top of the hour (last hourly interval >1 or <-1).
2. The pit module receives a two-way command (for example, a Read ERT using FDM software).
Error/Warning Flags
Register Error Detected. Register Error Detected indicates that the pit module is not communicating with the
register/meter. The tamper 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.
Extended Tamper Flag (retrievable with two-way communication).
Low Battery Warning. 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 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.
