6.6.25 Voltage Sag Level (VSag
LEVEL
) – Page 17, Address 1
Default = 0x00 0000
Voltage sag level, VSag
LEVEL
, establishes an input level below which a sag event is triggered.
This is a two's complement value in the range of -1.0
value 1.0, with the binary point to the right of the
MSB. Negative values are not used.
6.6.26 Current Overcurrent Duration (IOver
DUR
) – Page 17, Address 4
Default = 0x00 0000
Overcurrent duration, IOver
DUR
, determines the count of output word rate (OWR) samples utilized to deter-
mine an overcurrent event.
These are integers in the range of 0 to 8,388,607 samples. A value of zero disables the feature.
6.6.27 Current Overcurrent Level (IOver
LEVEL
) – Page 17, Address 5
Default = 0x7F FFFF
Overcurrent level, IOver
LEVEL
, establishes an input level above which an overcurrent event is triggered.
This is a two's complement value in the range of -1.0
value 1.0, with the binary point to the right of the
MSB. Negative values are not used.
6.6.28 Voltage Swell Duration (VSwell
DUR
) – Page 18, Address 46
Default = 0x00 0000
Voltage swell duration, VSwell
DUR
, determines the count of output word rate (OWR) samples used to deter-
mine a swell event.
These are integers in the range of 0 to 8,388,607 samples. A value of zero disables the feature.
