(45 kg) applied on the table.

3.3 CDS (Collision Detecting
System)
This table is equipped with a Collision Detection feature
designed to avoid possible severe injury due to pinching.
When the table detects a sudden change in resistance
(force) equal to approximately 120 lb (55kg) the CDS will
stop the movement of the table and reverse approximately
1 inch (25mm). CDS works in both directions, i.e. upwards
and downwards. Remove the obstacle prior to operating
the table again. The CDS will be active again as soon as
the table has been moved (up or down) 3,15 inch (80mm).
CAUTION—Risk of
pinching
The Collision Detection System (CDS) is a last resort
safety feature and is not designed to detect and prevent
all possible pinching and injuries. The effectiveness of the
CDS is effected by the speed of the table, the location
of the table top and the density of obstruction. Even in
the event that the CDS is activated it may not completely
prevent injury and all possible safety measures should be
taken in order to prevent possible injury.
CAUTION—Risk of
pinching
The Collision Detection System (CDS) is not enabled
during all resets and limit position calibration.
