15 GRID 1 Energy reset: When set, the accumulated energy for Grid 1 is reset and held
at 0 Wh and 0 VARh. When cleared, the Grid 1 energy value represents the
accumulated energy since power-up, or the last reset.
16 Relay open: Works with bit 32 to control the Sync Relay operation.
For more information, see "Relay Open/Relay Close Operation" on page 3-21.
17 GRID 2 Operation: 0 = disabled, 1 = enabled
If disabled, the PSM system does no measurements for the GRID 2 power grid.
Note: Both grids (bits Q1 and Q17) must be enabled in order for the PSM module to
act as a 2-source synchronizer.
18 GRID 2 Voltage selection:
0 = low voltage range (120VAC), 1 = high voltage range (600VAC)
Caution:
19 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 ,
• For 3-phase mode:
21 GRID 2 PTA_CA measurement: 0 = not measured, 1 = measured
Refer to "Reconstructed Variables", p. 3-21.
22 GRID 2 CTA measurement: 0 = not measured, 1 = measured
Refer to "Reconstructed Variables", p. 3-21.
23 GRID 2 PTB measurement: 0 = not measured, 1 = measured
Refer to "Reconstructed Variables", p. 3-21.
24 GRID 2 CTB measurement: 0 = not measured, 1 = measured
Refer to "Reconstructed Variables", p. 3-21.
25 GRID 2 PTC measurement: 0 = not measured, 1 = measured
Refer to "Reconstructed Variables", p. 3-21.
26 GRID 2 CTC measurement: 0 = not measured, 1 = measured
Refer to "Reconstructed Variables", p. 3-21.
27 GRID 2 CTN measurement: 0 = not measured, 1 = measured
Refer to "Reconstructed Variables", p. 3-21.
28 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.
29 GRID 2 Delta Mode: 0 = B phase is common, 1= C phase common
This bit must be set to 0 if the phase B is used as the common connection for the
other two voltages (North American standard). If the phase C is used as the common
phase in a Delta connection, this bit must be set to 1.
30 Reserved
31 GRID 2 Energy reset: When set, the accumulated energy for Grid 2 is reset and held
at 0 Wh or 0 VARh. When cleared, the Grid 2 energy value represents the
accumulated energy since power-up, or the last reset.
32 Relay close: Works with bit 16 to control the Sync Relay operation.
For more information, see "Relay Open/Relay Close Operation" on page 3-21.
PACSystems* RX3i Power Sync and Measurement System – February 2013
Function
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.
1 = 3-wire single phase using PTA and PTB
0 = WYE, 1 = DELTA
