GRID 2 Voltage selection:
0 = low voltage range (120VAC), 1 = high voltage range (600VAC)
CAUTION
The voltage range is determined by the physical connections in the system.
Changing this bit to a value that does not match the physical configuration
will result in erroneous power system measurements.

GRID 2 Grid Operational mode: 0 = single phase, 1 = three-phase
20
GRID 2 Connection mode:
Works with the Operational mode setting to determine system type.
•
For single phase mode: 0 = 3 single phases ,
1 = 3-wire single phase using PTA and PTB
•
For 3-phase mode: 0 = WYE, 1 = DELTA

GRID 2 1 Waveform Capture: changing from 0 to 1
When the PSM detects a change of this bit from a zero to one, it captures all 128
samples of all seven variables belonging to the grid.
