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 tripped. The LED 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 power meter’s
accuracy.
