5.1 Enable zone
The outputs (OSSD) are only enabled when a damping target is present in the en-
able zone� Outside this enable zone the outputs remain switched off�
The safe switch-off distance s
ar
is > 30 mm�
The enable zone is different if damping elements which deviate from the
standard target plate in terms of material, form and size are used�
Enable zone for selected materials*:
