7.2.3.1 LCD Relay Status
The Relay symbol identifies the current state of the meter relays and is read as follows:
•
The M symbol represents the state of the mail supply relay. This coincides with the 100 A in
the direct connect meters and the 2 A in the SGM30C2 meter model.
When the M is illuminated, the main supply relay is closed.
When the M is blinking, the relay is open, but the meter is ready for reconnection (by
pressing the physical reconnection button).
•
The LC1 and LC2 symbols represent the state of the load control relay(s). LCI coincides with
the 40 A relay in the direct connect models and the second 2 A relay in the SGM30C2
model. LC1 coincides with the 2 a relay in the SGM3013, SGM3023, and SGM3033 models.
When LC1 and LC2 are illuminated, the meter relay is closed.
When LC1 and LC2 are blinking, the relay is open but boast is enabled and the relay can
be closed (by pressing the physical reconnection button).

7.2.3.2 LCD Phase Voltage Status
The A B C symbol identifies if voltage is present on each phase of the meter.
•
When A B C is illuminated, voltage is present.
•
When A B C is not illuminated, there is no voltage present.
•
If A B C is blinking, voltage is low.
