7.9 Ramp function
With the ramp function, temperature changes over any time period can be conveniently entered. This is
especially advantageous with very low temperature changes (e.g. 0.1 °C/ day).
Example: From the current outflow temperature (e.g. 242.4 °C) 200 °C of cooling is to occur over 5
days.
Then 200 °C is entered as the temperature change, the time value 5 is entered for the time and day(s)
selected as the time unit.
The ramp function is executed until it is manually terminated or until the temperature limits
T
il
(min) or T
ih
(max) described in Section 7.6.2 are attained.
