Each program starts with the segment
Start
, which determines the tem-
perature at which segment
1
continues the program. The temperature of the
Start
segment is reached as quickly as possible. It is not possible to specify
a time limit for the
Start
segment. Without the
Start
segment, segment
1
would be different depending on the heat transfer liquid temperature at
program start.

In the edited table, a new segment with the number 3 has been entered.
The time and the pump level for segment 4 have also been modified. The
tolerance and pump level for segment number 5 have been adapted.

In the Integral T in the Pumpcolumn

Note the following and see Fig. 64:
n
The Tolerance field ensures strict compliance with the residence time at
a specific temperature, for example.
n
The subsequent segment is only processed when the outflow tem-
perature reaches the tolerance range (1) so the ramp in the second
segment is delayed and only starts at 2, for example.
