Parameter for determining in which set of parameters a par-
ticular function is active
Trip
defines the tripping channel activated by the tripping O/P of
the function (matrix tripping logic).
c-Setting
Setting for the exponential factor determining the shape of
the operating characteristic according to BS 142 or for se-
lecting the RXIDG characteristic.
k1-Setting
Constant determining the parallel shift of the characteristic
(time grading).
I-Start
Pick-up current at which the characteristic becomes effective.
t-min
Definite minimum tripping time.
NrOfPhases
defines the number of phases measured.
