Recommended settings for diagnostic limit values
In the "Diagnostics / Diagnosis Control / ..." menu, limit values for the diagnostic values can be
specified.
In order to simplify their setting, recommendations for the individual limit values are shown here.
The values indicated are only intended as a rough guide and may need to be adapted in line
with on-site conditions.
