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 500W ERT 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.
4. 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).
