Explanation of parameters:
ParSet 4..1
Parameter for determining in which set of parameters a par-
ticular function is active
Trip
defines the tripping channel activated by the tripping output of
the function (tripping logic).
Delay
Time between the function picking up and tripping.
Z-Setting
Pick-up impedance setting.
NrOfPhases
defines whether single or three-phase measurement.
CurrentInp
defines the analogue current input channel.
All current inputs may be selected.
In the case of three-phase measurement, the first channel
(R phase) of the group of three selected must be specified.
