1.4.5 Travel and switching diagram for short travel distances
The electronics of the C−LRV valve make it possible to control stops at
mezzanines and similar short travel distances with the same ride comfort
as in normal travel.
Important: The maximum speed should be reduced to a value that,
despite the short travel distance, can actually be attained.
