GRID 1 PTA_CA measurement: 0 = not
measured, 1 = measured Refer to
“Reconstructed Variables
”, p. 53.

GRID 1 CTA measurement: 0 = not measured, 1 = measured Refer to “Reconstructed
Variables
”, p. 53.

GRID 1 PTB measurement: 0 = not measured, 1 = measured Refer to “Reconstructed

GRID 1 CTB measurement: 0 = not measured, 1 = measured Refer to “Reconstructed

GRID 1 PTC measurement: 0 = not measured, 1 = measured Refer to “Reconstructed
Variables
”, p. 53.

GRID 1 CTC measurement: 0 = not measured, 1 = measured Refer to “Reconstructed

GRID 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.
13
GRID 1 Delta Mode: 0 = B phase is common, 1= C phase is 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.

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 54.
17
GRID 2 Operation: 0 = disabled, 1 = enabled
If disabled, the PSM system does no measurements for the GRID 2 power grid.
Note: If you are installing the ground plate on a painted surface, the paint must
be removed where the ground plate is to be mounted to ensure a good
ground connection between the plate and mounting surface. Both grids
(bits Q1 and Q17) must be enabled in order for the PSM module to act as a
2-source synchronizer.
