Installation Guide

4. Quiet mode
–
Meter manufacturers can configure the Cellular 500W remote module for quiet mode
after programming and direct mounting the Cellular 500W remote module in a factory.
–
The Cellular 500W remote module is awakened from quiet mode and enters run mode in
one of two ways:
•
Counting two pulses. The pulses are counted internal to the Cellular 500W remote
module while it is in quiet mode.
•
Receiving a two-way command, such as a Read using FDM.
If a Cellular 500W remote module installed in quiet mode is not bubbling up SCM+ messages, it
may be due to zero consumption on the Cellular 500W remote module , such as a vacant or
vacation home. Initiate a two-way command (for example, perform a Read with FDM) before
removing the unit.
