Page 5-5
The Wallstand has a detector holder with loading from the left side, enabling the operator to
work from an optimal position at all times
A System installed in a room with similar size and with the components placed as described in
Figure 5-2 , usually requires 16 m cable length, which also is the standard configuration, see
also System connections in chapter 5.
Wallstand loading and positioning should be carefully planned, since it will have large impact
on the final layout of the room. If the use of armrest is restricted to one side it is also possible
to move Wallstand closer to wall.
If recommended dimension are overridden, necessary notifications, warnings and instructions
have to be considered. This includes safety distances and trapping zones around motorized
movements according to IEC 60601-1 3rd edition.
•
(*1x) and (*1y) is chosen considering a limited stroke of the table top (X +/- 400 y +/
-150) and a 500mm clearance to wall and cabinet. If cabinet is placed somewhere
else (*1y) is minimum 1100mm. If lateral projection should be performed see (*3) for
minimum requirements. Smaller rooms require further table top stroke limitations
(max table top movement range X +/-5 00mm, Y +/-150).
•
(*2) is chosen due to the room size in layout 1 ( Figure 5-2 ) and centers the focal spot
coverage area in X-direction related to the room and Table. (*2) must not be less
than 100 mm.
•
(*3) is chosen considering a lateral projection from the back side of the Table. If the
table top is centered over the Table minimum distance is 1289mm. A minimal dis-
tance of 1189 mm can be chosen, but requires that the table top is moved to its outer
position (towards the front of the Table).
•
(*4) is chosen to give the traverse cable outlet enough clearance to the wall.
•
(*5) is chosen to give the operator enough space to work freely with the Ceiling sus-
pended unit and the Wallstand (see also (*6) ). It’s allowed to mount armrest on both
sides when those minimum and maximum dimensions are withheld. Both left hand
load detector holder (LL) and right hand load detector holder (RL) are described with
minimum and maximum dimensions.
•
(*5) is also chosen to give the operator enough space to work freely with the bucky/
detector holder since the chosen configuration is loaded from the left side. The
traverse cable outlet (*7) shall, if possible, always be placed as suggested in Figure
5-2 , since the cable conduits will be in the way of the operator in a projection against
the Wallstand. If the recommended placing of the traverse cable outlet is not possi-
ble, the projection against the Wallstand requires that the tube is rotated to position
D. (consider heel effect)
•
(*6) is chosen to enable a SID of 1800mm (2000mm SID requires that the table top
is moved towards the back of the Table).
•
(*8) is chosen to be able to align the tube and the Wallstand. Maximum and minimum
dimensions are stated on the drawing. See also (*5).
•
(*9) must not be less than 250 mm due to the cable outlet of the Wallstand.
