1.4 Entering numerical values
A numerical pad is used to enter numerical values. It will be displayed when
you have to enter values.
- Deleting the value in an entry box
-
Changing the leading sign of a value
- Closing the keypad. Changes made to the nominal value
are not saved.
- De-activating a nominal value
-
Saving an entered value
Be aware
The controller also allows you to enter negative temperature values:
- In order to pre-program negative nominal values in a step, the installation manufacturer
has to pre-program negative nominal value limits for chamber and core.
-
„0“ can be entered as a nominal value. The nominal value „Off“ is shown for chamber
and core when a new program step is pre-programmed. . This means: the nominal value
is deactivated. As soon as a value is entered (even if it is
„0“) the nominal value counts
as activated. If you want to deactivate the nominal value later in the step, press
the
„Off“ button.
