buttons “up” and “down” to focus an entry

subsequent or previous item.

Relevance of the nominal values
The controller allows you to pre-program different nominal values within a program step. In the
following chapter, the relevance of the individual nominal values is explained.
Be aware
Depending on the system and the application, nominal values can be configured in different
ways for individual processes. This means that you may find that not all the nominal values
described here are available in your controller
(it depends on your specific configuration)
.
This manual describes all the available values
4.1 Entering nominal values
Nominal value entry will be automatically cancelled after 10 seconds, if none of the buttons have
been pressed.
The nominal value that is shown at that time is saved.
4.2 Switching off nominal values
Be aware
Switching off nominal values:
Nominal values in the controller can also be negative. Therefore value „0“ is also a valid
nominal value. If you want to switch off a nominal value in a program step, e.g. the core
temperature, the
button (MKA500) /
(MKA800)
has to be pressed repeatedly until
the value „OFF“ appears.
