Explanation of parameters:
ParSet 4..1
Parameter for determining in which set of parameters a par-
ticular function is active
Trip
Tripping logic (matrix) for this function.
Theta-Begin
Initial temperature rise. This temperature rise is set every
time the function is initiated, e.g. when the protection is
switched on or settings are changed.
Theta-Warn
Temperature rise at which alarm is given.
Theta-Trip
Temperature rise at which tripping takes place.
NrOfPhases
No. of phase currents measured.
CurrentInp
defines c.t. input channel.
All the current channels are available for selection. In the
case of a three-phase measurement, the first channel
(R phase) of the group of three must be selected.
