GRID 1 CTC measurement: 0 = GRID 1 CTC not connected, 1 = GRID 1 CTC connected
10
The PSM module reconstructs the missing variable. Refer to Reconstructed Variables in GFK-2749.
GRID 1 CTN measurement: 0 = GRID 1 CTN not connected, 1 = GRID 1 CTN connected
11
The PSM module reconstructs the missing variable. Refer to Reconstructed Variables in GFK-2749.
12 GRID 1 Waveform Capture: When this bit is transitioned from 0 to 1 by the control logic, the PSM module
captures 128 samples of all seven data variables on GRID 1.
GRID 1 Delta Mode: 0 = B phase is common, 1= C phase is common
13
This bit must be set to 0 if 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.

14
GRID 1 Energy reset: When set, the accumulated energy values for GRID 1 are reset and held
15
at 0 Wh and 0 VARh. When cleared, the GRID 1 energy values represent the accumulated energy since
the last reset.
Relay open: Works with bit 32 to control the Sync Relay operation.
16
For more information, refer to Relay Open/Relay Close Operation in GFK-2749.
GRID 2 Operation: 0 = disabled, 1 = enabled
17
If disabled, the PSM module does no measurements for the GRID 2 (generator grid) inputs.
Note: Both grid control offset bits (Q1 and Q17) must be enabled in order for the PSM module to
operate as a 2-source synchronizer.
GRID 2 Voltage Selection: 0 = low voltage range (120VAC), 1 = high voltage range (600VAC)
18
Caution: The voltage range is determined by the physical connections in the power system. Changing
19 GRID 2 Grid Operational Mode: 0 = single phase, 1 = three-phase
GRID 2 Connection mode:
20
Works with the Grid Operational Mode setting to determine system type.
• In single phase mode: 0 = Three single phases ,1 = Three-wire, single phase (120/240) using
PTA and PTB
• In three-phase mode: 0 = WYE system configuration, 1 = DELTA system configuration
GRID 2 PTA measurement: 0 = GRID 2 PTA not connected, 1 = GRID 2 PTA connected
21
The PSM module reconstructs the missing variable. Refer to Reconstructed Variables in GFK-2749.
GRID 2 CTA measurement: 0 = GRID 2 CTA not connected, 1 = GRID 2 CTA connected
22
The PSM module reconstructs the missing variable. Refer to Reconstructed Variables in GFK-2749.
GRID 2 PTB measurement: 0 = GRID 2 PTB not connected, 1 = GRID 2 PTB connected
23
The PSM module reconstructs the missing variable. Refer to Reconstructed Variables in GFK-2749.
GRID 2 CTB measurement: 0 = GRID 2 CTB not connected, 1 = GRID 2 CTB connected
24
The PSM module reconstructs the missing variable. Refer to Reconstructed Variables in GFK-2749.
GRID 2 PTC measurement: 0 = GRID 2 PTC not connected, 1 = GRID 2 PTC connected
25
The PSM module reconstructs the missing variable. Refer to Reconstructed Variables in GFK-2749.
GRID 2 CTC measurement: 0 = GRID 2 CTC not connected, 1 = GRID 2 CTC connected

reset.
this bit to a value that does not match the physical configuration will result in erroneous power
system measurements. Note: Do not change this value in while in RUN mode.
