Figure 34: Control panel of the X-ray tube
The operation controls of the X-ray tube head unit are located at the control
panel. The X-ray tube can be positioned by the operator manually.
To release the brake for the selected movement direction or rotation, press
and hold the button and move the X-ray tube head unit. To improve the ease of
performing the movement, the movement is supported by motors.
To stop the movement and activate the brake, release the button.
The display of the control panel shows the rotation angle of the X-ray tube and
the SID value. The SID value can only be calculated correctly when the X-ray
tube is perpendicular to the bucky of the radiographic wall stand. This
function does not account for physical alignment of the X-ray source to the DR
detector. Always visually verify that the X-ray source is aligned to the DR
detector before taking exposures!
To avoid collisions, the movement of the radiographic table is blocked until
the X-ray tube of the ceiling suspension is moved back into the parking
position. The parking position of the ceiling suspension can be detected by
detents on the rails.

WARNING:
If movement in any direction blocks, do not apply force to
overcome the blocking. Contact your local service organization.
