The following section (in our example now S03) is displayed:

If you delete a program section which is followed by further sections, those following move up
in place of the deleted section.
In our example, section S03 has been deleted. If sections S04, S05, etc. have been programmed earlier,
they will now replace the preceding sections, i.e., S04 is now called S03 etc.
Deletion leads to overwriting the section by the following one. It is therefore not possible to temporarily
inactivate a program section. To enter a section later to a program, all the sections following the new one
must be entered again.

Program start level

Before starting the program, check the set-point entered in Fixed value operation mode. After end of the
program, the temperature will equilibrate to this value. This value must NOT exceed the maximum per-
missible drying temperature of a solvent contained in the drying material.
Exceeding the ignition temperature of a solvent after the program ends.
Risk of fire and explosion.
Danger of death.
∅ Set-point of Fixed value operation must NEVER reach the ignition temperature of a
contained solvent. For safety reasons, always ensure that there is a safety margin
(chap. 2.5).
 Check the set-point of Fixed value operation and if necessary adapt it acc. to the tem-
perature setting information panel (chap. 2.5).
After the program ends, the temperature will equilibrate to the set-point entered in Fixed value operation
mode. If the week program timer is active, another set-point (SP2) may be targeted according to pro-
gramming. Too high temperatures can occur which exceed the maximum permissible drying temperature
of a solvent contained in the drying material. Deactivate the week program timer before starting the pro-
gram (default setting, setting in the User level, chap. 10).
Exceeding the ignition temperature of a solvent after the program ends.
Risk of fire and explosion.
Danger of death.
 Deactivate the week program timer before starting the program.
