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 the temperature change is entered as 200°C and the time as 5 days.
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 7.8.3 are attained.
