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.
