These points are formatted as 2's complement fractions. They represent a fraction of
4500W Secondary in normal operation, or 3000W Secondary in Open Delta operation.
Inputs above/below +/-4500 or +/-3000W Secondary are pinned at +/-4500 or +/-
3000W Secondary, respectively.
Total VA (Point 12)
This point is formatted as a 2's complement fraction. It represents a fraction of
4500W Secondary in normal operation, or 3000W Secondary in Open Delta operation.
Inputs above/below +/-4500 or +/-3000W Secondary are pinned at +/-4500 or +/-
3000W Secondary, respectively.
Power Factor (Point 13)
This point is formatted as a 2's complement integer. It represents Power Factors from
-1.000 (0x0FC18) to +1.000 (0x003E8). In Open Delta operation, Total Power Factor
(Point 13) is always zero.
Frequency (Point 14)
This point is formatted as a 2's complement fraction. It represents the Frequency as
measured on Phase A Voltage in units of cHz (centiHertz, 1/100 Hz). Inputs below
45.00 Hz are pinned at 0 (0x0000); inputs above 75.00 Hz are pinned at 9999
(0x270F).
