174 Setpt 1 Limit
Creates a tolerance - hysteresis band around the value in
parameter 173 [Setpt1 TripPoint]. Turn-on level for ascending
data = TripPoint - Limit. Turn-off level for ascending data =
Tri 2(Limit). Turn-on level for descending data =
Tri Limit. Turn-off level for descending data = TripPoint
- 2(Limit).
