Collision Protection; Information On Collision Protection; Notes On Use - VS 910 Series Operating Instructions Manual

3. Collision protection

Caution! The collision protection is not an entrapment or personal
protection mechanism! For physical reasons, "soft" obstacles may
only be poorly detected and evaluated or may not be detected at all!
If the table travels against an obstacle then it is possible that the
obstacle may suffer damage because the table travels against it at
its nominal speed!

3.1 Information on collision protection

- If the table meets and detects an obstacle when traveling either
upwards or downwards then the upward travel protection prevents
the table from inclining or continuing its travel. If an obstacle is
detected then the table stops moving and reverse travel is initiated
automatically (difference in reverse travel: approx. 5 cm)

3.2 Notes on use

- Start/acceleration phase: Once travel has started, obstacles can only
be detected after travel of approximately 2 cm, after the nominal
speed has been reached.
- Load: If the table is not subject to any load then obstacles cannot
be or can only be poorly de
- Soft obstacles: Soft obstacles include all types of obstacle that
initially give way when the table travels against them, for example
as in the case of human body parts, upholstered chairs etc. Soft
obstacles cannot be or can only be poorly detected.
- Operating time restriction: The electronics monitor how long the
drives have been operating. If the maximum permitted time is
exceeded then the electronics do not permit continued operation
of the drives (see section 8).
