Gendex ORTHORALIX 9200 - Technical Data and Pre-installation

ORTHORALIX 9200 Service Manual

Gendex Dental Systems 4519-190-71193-7
A.4.7 Remote control box
The remote control box with exposure handswitch enables the
operator to take an X-ray in a separate room.
It is equipped with a 20m cable for connection to the equipment,
and incorporates an “X-ray ON” buzzer and indicator light.
A cable inlet is available on the bottom plate of the column.
There is a socket for connecting the handswitch coiled cable (1 m
long) and a hook for hanging the same handswitch.
In order to comply with Federal regulations this remote box
must be installed so the technique factors are visible to the
operator from the remote location.
A.5 Technical data
A.5.1 Pre-installation
A.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 sup-
plied 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/cm2).
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).
A.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.
A.5.1.3 Floorspace
For the system dimensions applicable to the different versions
refer to A-13.
A.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 imple-
mented 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.
A.5.2 Mechanical data
The system is light-weight thanks to the manufacturing technol-
ogy of the high tension transformer, which in turn allows more
compact mechanical dimensioning of the rotary unit and the
column.
A.5.2.1 Driving system
The Orthoralix system provides a microprocessor-controlled mo-
tor driving system, with use of stepping motors, for independent
control of four separate movements:

(ceph DDE versions only).
In addition, the patient head rest and the column are also motor-
ized.
Drive transmission is by means of tension belts.
