Operation of Slope
.
▪ When changing TSP, the ramping rate is given from NPV to TSP by gradually changing NSP.
▪ Operation of SLOPE
▶ SLOPE : 20.0 ℃/MIN
Amount of change to TSP = [SP(TSP) - NPV] and Slope = 20.0℃/min.
→ (70.0 - 30.0 )℃ = 40.0℃, it will take 2 min to ramp up to TSP.
☞ For 2 minutes, NSP will be changed from 30.0℃ to 70.0℃ at a constant rate of 20℃/min.
