EnaAbs = Absolute
RefSource = SetValue
SetValue = 100
RefPrefix = Kilo
EqualBandHigh = 5.0 % of reference value
EqualBandLow = 5.0 % of reference value
Operation
The function will set the outputs for the following conditions,
INEQUAL will set when the INPUT is between the ranges of 95 to 105 kA.
INHIGH will set when the INPUT crosses above 105 kA.
INLOW will set when the INPUT crosses below 95 kA.
If the comparison should be done between two current magnitudes then those current signals
need to be connected to function inputs, INPUT and REF. Then the settings should be adjusted
as below,
EnaAbs = Absolute
RefSource = REF
EqualBandHigh = 5.0 % of reference value
EqualBandLow = 5.0 % of reference value .
