G	Remote display connection activity

See below for more information about each LED:
Alarm LED

State	Description
Off	No active alarms
On	Acknowledged active alarm
Flashing	Unacknowledged active alarm

Status/operation LED:

LED	Description
Off	Meter is not powered
Green	Normal operation
Red	Flashing: No communications to display On: Firmware upgrade required

(Infrared) Energy pulsing LED:
Energy pulsing is used to help verify the energy measurement accuracy of the meter for revenue purposes.
The visible and infrared LEDs are configured by default to pulse based on energy measured by the meter.
The pulse weight (pulses per kWh) and the energy source can be configured, except in the case of the PM82401 which requires a specific pulse weight for MID compliance.

Revenue lock LED:
The revenue lock LED indicates the lock status of the meter

State	Description
Off	The meter is not revenue locked.
On	The meter is revenue locked
Flashing	New revenue lock state is pending. Power cycle your meter to set the revenue to on or off

Remote display connection LED:
There are two LEDs in the remote display connector that indicate the state of communications between the meter and remote display.

LED	Description
Green (link)	On: link established. Off: no link established with the remote display. Check the connections to the remote display and DIN meter.
Yellow (activity)	Flashing: active communications between the meter and the remote display. Off: no communication activity. Check remote display and meter operation.
