• 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
For OpenWay Riva modules reporting in ChoiceConnect 100S mode.
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.
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.
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.
For OpenWay Riva modules operating in OpenWay Riva Network mode.
