TECHNICAL DATA

PRE-INSTALLATION

5.1.1. Preparing the installation site

Orthoralix 9200 is to be mounted on a normal masonry wall.
It takes three men to attach the column to the wall and to mount the
Z-carriage to the column.
The remaining installation work can be done by one engineer,
following the instructions given in section B of this manual.
Only the standard toolset is required.
Any special devices required for set up and adjustment are supplied
as accessories with the unit.
The system is designed to be fixed to the wall by means of six
bolts.
For this purpose screws M6 with metal expansors are suggested
(supplied); they are only suitable for use with concrete walls type
R300 and over (resistance to compressive load greater than 300
kg/cm 2 ).
For other wall types, please refer to the detailed instructions given
in section B.
Irregularities in the floor level, within a 2mm/m tolerance, can be
compensated at installation time by means of levelling shims (supplied
with the unit).

5.1.2. Headroom

The system height is 2310 mm high.
A minimum headroom of 2340 mm is required to install it.
To dismount the internal parts of the column, such as the slide block
with ball bearings, a minimum headroom of 2650 mm is required.

5.1.3. Floorspace

For the system dimensions applicable to the different versions refer
to AZ-1.

5.1.4. X-ray protection

The machine is intended for (indoor) dental practice without special
X-ray protection in walls, floors and ceilings.
X-ray protection comes from the distance to be kept from the unit,
proper X-ray beam collimation and inherent shielding implemented
in the machine.
Primary X-ray beams are shielded by a lead plate, located at the
rear of the cassette unit (thickness: 1.5 mm in Pan and Transcan
mode, 1 mm in Ceph mode).
In the DDE versions, the X-ray beams are shielded by the sensor
assembly, introducing a filtration equivalent to 1.5 mm of lead.

MECHANICAL DATA

The system is light-weight thanks to the manufacturing technology
of the high tension transformer, which in turn allows more compact
mechanical dimensioning of the rotary unit and the column.

5.2.1. Driving system

The Orthoralix system provides a microprocessor-controlled motor
driving system, with use of stepping motors, for independent control
of four separate movements:
- X-positioning of rotation centre
- Y-positioning of rotation centre
- rotation of rotating arm
- linear translation of film cassette
- linear translation of digital CCD sensor and secondary
collimator (ceph DDE versions only).
In addition, the patient head rest and the column are also motorized.
Drive transmission is by means of tension belts.
