Heartbeat / serial communications LED

The heartbeat / serial communications LED blinks to indicate the meter’s operation and serial Modbus communication 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 technical problem. In this case, power down the meter and reapply power. If the LED still does not blink or flash, contact Technical Support.
