7. Programming enable

The unit has 2 types of programming enable which must both be set to "ON" to change the
settings. The operating programming enable can be set or removed during operation. It
provides protection from unintentional alteration. A programming disable via the main
programming enable has the effect that no change to the settings can be carried out during
operation. This serves, for example, as a safety function or as protection against
unauthorised alterations.

7.1 Altering the operating programming enable

7.2 Altering the main programming enable

Switch off supply voltage or disconnect the unit from the supply voltage.

Note:

· If a setting has been changed "PRG" is displayed briefly when the display is switched

over. The new setting is then saved in the unit.
