Quick commissioning menu, when switching on for the
first-time or after executing command "Factory settings"
Information on quick start menu
After supplying the control voltage for the first time, you will be
automatically directed to the quick start menu. You must
complete the entire quick start menu to commission the soft
starter.
If you confirm the last item "Save settings?" with "yes" in the
quick start menu, you can only return to this menu by resetting
the device back to the basic factory settting. (See manual or
operating instructions)
This overwrites all settings made up until that point.
Information on application selection:
Standard parameters are recommended on the basis of the set
type of application.
If the required load is not listed, choose a fan in order to
preselect the necessary start parameters.
In general:
The parameters are suggested settings.
The parameters may need to be optimized, as explained in the
Section "Start command "Soft starter on".
