2.9. Power Modes
To keep power consumption to a minimum, especially for remote sites, the FB2100 can
run in two different power modes – Low Power Mode (4 MHz or 8 CPU MHz clock speed)
or Standard Power Mode (60 MHz CPU clock speed).
Low Power Mode
The FB2100 normally runs in low power mode for typical metering applications. The radio
Power Control function (configurable in FBxConnect) switches the flow computer into
standard power mode at specific times when serial communications are required, then it
reverts to low power mode when the communication period is over. A serial connection to
a remote 4088B MVT can occur in low power mode.
The local display (HMI module) with FBxWifi uses additional power. You can configure it in
FBxConnect to shut down after a period of inactivity.
