2.10 Safety Functions

WARNING!
The operator must always have supervision of the System.
2.10.1 Table Safety Zone and OTC
There is a safety zone over and around the Table. The safety zone reaches from the table
top surface and vertical up 500 mm and from the table top edge and horizontal out 120 mm.
Inside the zone the OTC moves vertically with reduced speed. Not until the OTC is outside
the zone the vertical movements are performed with full speed.
WARNING!
When the stand has passed the table top level, on its way downward, the speed will in-
crease to normal speed again.
Additionally, when the stand moves manually down into the zone, at a distance of 50 cm from
the Table, the OTC stops the vertical movement and the movement has to be restarted by re-
leasing and pressing the button again.

2.10.2 Wallstand Safety Zone

With consideration of detector tilting and the safety height of the tube, there is a collision vali-
dation when moving in Auto-position. The System validates if it is possible to move to the po-
sition, without any collision between tube and detector.
In Wall Flexible mode, when user activates the Servo button and Z reaches the transport in-
terval zone, the System checks the Auto-position target with the detector tilting and the
safety height of the tube to detect possible collision points. The System then moves, or stops
moving and displays message.

2.10.3 Collision Detection

2.10.3.1 Motorized Movements
Every motorized movement has a collision detection.
All movements are stopped when the collision detection activates and the display shows an
error message. When a collision in Z-direction is detected, the OTC has to be moved in the
opposite direction before it can be moved in the original direction again.
2.10.3.2 Z Column
A guard plate installed on top of the column, registers vertical pressure on the column, for in-
stance a vertical impact.
When the pressure exceeds the trig level vertically, all movements are stopped and a warn-
ing message is displayed. To be able to release the pressure, a movement in the opposite di-
rection is allowed. When the pressure on the column has returned to normal, see Fig. 2-13
Collision detection the warning message is removed and motorized movements are allowed
again.
