The heartbeat / serial communications LED blinks to indicate the meter’s operation and serial Modbus communications status.
The LED blinks at a slow, steady rate to indicate the meter is operational. The LED flashes at a variable, faster rate when the meter is communicating over a Modbus serial communications port.
You cannot configure this LED for other purposes.
NOTE: A heartbeat LED that remains lit and does not blink (or flash) can indicate a hardware problem.
