Front panel LEDs
C Alarm / energy pulsing LED (orange)
B Heartbeat / communications LED (green)
Heartbeat / communications LED
The (green) heartbeat / communications 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) indicates a possible hardware problem. In this case, power down the meter and reapply power. If the LED still does not blink or flash, contact Technical Support.
Alarm / energy pulsing LED modes
The (orange) alarm / energy pulsing LED can be configured for alarm notification or energy pulsing.
•When configured for alarm notification, this LED flashes when a high, medium or low priority alarm is active. This provides a visual indication of an active alarm condition, or an inactive but unacknowledged high priority alarm.
•When configured for energy pulsing, this LED flashes at a rate proportional to the amount of energy consumed. This is typically used to verify the meter’s accuracy.
