Default = 0x00 0000

Voltage sag level, VSagLEVEL, 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.

Default = 0x00 0000

Overcurrent duration, IOverDUR, 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.

Overcurrent level, IOverLEVEL, 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.

Voltage swell duration, VSwellDUR, 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.
