See section 13.5.1.1.1 for further information.
Phase Peak-Change Fault Detector (0.125-5 inc 0.125)
This is used to set the threshold for the peak-change fault detectors for phase A, B, and C. The setting
must be between 0.125A
RMS
and 20A
RMS
(inclusive) in increments of 0.125A
RMS
.
See section 13.5.1.1.2 for further information.
Ground Peak-Change Fault Detector (0.125-5 inc 0.125)
This is used to set the threshold for the peak-change fault detector for phase A, B, and C. The setting
must be between 0.125A
RMS
and 20A

.
TX Logic Bus Start Bit (3-511 inc 1)
Sets the beginning position of the TX logic bus time-slot. TX logic bus time-slot refers to data driven
onto the logic bus by the current differential module. This value is factory set and should not be
changed without knowledge of System Logic programming.
TX Logic Bus Length (0-80 inc 1)
Sets the length of the TX logic bus time-slot. This value is factory set and should not be changed
without knowledge of System Logic programming.
RX Logic Bus Start Bit (3-511 inc 1)
Sets the beginning position of the RX logic bus time-slot. RX logic bus time-slot refers to data
retrieved from the logic bus by the current differential module. This value is factory set and should not
be changed without knowledge of System Logic programming.
RX Logic Bus Length (0-24 inc 1)
Sets the length of the TX logic bus time-slot. This value is factory set and should not be changed
without knowledge of System Logic programming.
After all the settings have been entered click the “Save” button to save your configuration, a
