Explanation of parameters:
ParSet 4..1
Parameter for determining in which set of parameters a par-
ticular function is active (see Section 5.11.).
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.
