8.4.1 Voltage Sag and Current Fault Duration (V1Sag
DUR
, V2Sag
DUR
, I1Fault
DUR
, I2Fault
DUR
)
Address: 0 (V1Sag
DUR
), 8 (V2Sag
DUR
), 4 (I1Fault
DUR
), 12 (I2Fault
DUR
)
Default = 0
Voltage sag duration,
V1Sag
DUR
(V2Sag
DUR
) and current fault duration, I1Fault
DUR
(I2Fault
DUR
) determine
the count of output word rate (OWR) samples utilized to determine a sag or fault event. These are integers in
the range of 0 to 8,388,607 samples. A value of zero disables the feature.
8.4.2 Voltage Sag and Current Fault Level (V1Sag
LEVEL
, V2Sag
LEVEL
, I1Fault
LEVEL
, I2Fault
LEVEL
)
Address: 1 (V1Sag
LEVEL
), 9 (V2Sag
LEVEL
), 5 (I1Fault
LEVEL
), 13 (I2Fault
LEVEL
)
Default = 0
Voltage sag level,
V1Sag
LEVEL
(V2Sag
LEVEL
) and current fault level, I1Fault
LEVEL
(I2Fault
LEVEL
) establish
an input level below which a sag or fault is triggered. These are two's complement values in the range of
-1.0
value 1.0, with the binary point to the right of the MSB. Negative values are not used.

8.5.1 Temperature Measurement (T
MEAS
) – Address: 26
Default = 0
The Temperature Measurement (
T
MEAS
) register is used to cycle-steal voltage channel2 for temperature
measurement. Writing a one to the LSB causes the temperature to be measured and the Temperature register
(
T) to be updated.
Refer to 6.13
Temperature Measurement on page 22 for more information.
