3. Meter Manufacturer Quiet Mode
• Meter manufacturers can configure the ERT module for Quiet mode after initializing and direct
mounting the 100W in the factory.
• The ERT module awakens from Quiet mode and enters Run mode in one of two ways:
1. The 100W detects consumption at the top of the hour (last hourly interval >1 or <-1).
2. The 100W receives a two-way command (for example, a Read ERT using FDM software).
100WP Operating Modes
The 100WP has three standard operating modes.
1. Factory Mode
• 100WPs ship from the factory in Factory Mode.
• The 100WP's transmitter is off.
• The 100WP's receiver bubbles-up to listen for a programming command.
• Last Good Read and Extended Tamper Flags may be set when a register is not connected.
• You must program the 100WP with the initial consumption and the register type to properly move the
ERT module to Run mode and record consumption. You can program the 100WP in the field with
FDM or in the factory using custom programming.
2. Run Mode
• 100WPs normal operation mode.
• The 100W transmitted message is dependent on its factory settings or Field Deployment Manufacturer
(FDM) programming for standard consumption messages (SCM) or network interval message (NIM).
o For SCM (Mobile), the 100WP default bubble-up rate is 9 seconds.
o For NIM (Fixed Network), the 100WP default bubble-up rate is five minutes. When the ERT
module is set for NIM, the 100WP transmits a contingency SCM message every minute. NIM
mode is configured by programming NIM mode with a programming device.
3. Meter Manufacturer Quiet Mode
• Meter manufacturers can configure the 100WP for Quiet mode after programming and direct
mounting the 100WP in a factory.
• The 100WP is awakened from Quiet mode and enters Run Mode in one of two ways:
o Counting two pulses. The pulses are counted internal to the 100WP while it is in Quiet mode.
o Receiving a two-way command, such as a Read ERT using FDM.
• If an ERT module installed in quiet mode is not bubbling up SCM or NIM messages, it may be due to
zero consumption on the ERT module, such as a vacant or vacation home. Initiate a two-way
command (for example, perform a Read ERT with FDM) before removing the unit.
