this section.
3.0.1 Intended use
The machine and the manufacturing software have
been designed for the commercial processing of
approved dental materials by specially trained persons.
The processed objects require additional work before
their use on patients.
Only process materials that you can select in the
manufacturing software.
Only use the machine and manufacturing software in
a commercial environment.
Before creating jobs, verify if the objects being pre-
pared may be utilized at the place of use according
to local and/ or national regulations or other author-
ized organizations or entities (e.g. professional asso-
ciations, health authorities). In particular, verify if the
material is approved for the machined object type
and if the object type is designed in accordance with
applicable regulations. Neither the manufacturing
software nor the machine will inform you about pos-
sible regulatory infringements, but will execute jobs
in accordance with the preferences and materials set
by the user.
Verify that each object type and each material in
your jobs are authorized manufacturing materials. If
mandated by local or national regulations, obtain rel-
evant authorization from the responsible organ-
izations or entities (e.g. professional associations,
health authorities).
Only import objects into the manufacturing software
which correspond to the object types that you can
select in the manufacturing software. While you can
import/ manufacture any other objects as well,
neither the manufacturing software nor the machine
are designed for these other objects and should not
be used in this way.
Do not manufacture implants or parts of objects that
are designed to have contact with implants. These
parts include parts of two-part abutments which
contain the connection geometry for the implant.
Do not manipulate the connection geometry of pre-
fabricated abutments (“prefab abutments”) and you
must always check finished objects for accurate con-
nection geometries (i.e. that connection geometries
of finished jobs have not been damaged).

4 MACHINE OVERVIEW
With your S5 you can process blanks of different mater-
ials to create high quality objects for the dental sector.
You can find a list of the materials which you can
process with the machine in the manufacturing soft-
ware.
The blank changer of the S5 allows you to process up
to 8 jobs in succession without having to start each job
manually.
The machine is designed for wet and dry machining.
During wet machining, the tools and blanks are
constantly being cooled by cooling liquid.
During dry machining, our anti-soiling concept
reduces the soiling of sensitive machine parts.
Wet machining requires the optional vhf wet grinding
module. The wet grinding module and the required
cooling lubricant Tec Liquid Pro are available from
customer service.

To operate the machine, you must use a computer
running Windows®(“CAM computer”) and specially
designed software (“manufacturing software”). The
manufacturing software consists of the following
components:
nDENTALCAM ‒A CAM application for creating
and calculating virtual blanks (“jobs”).
nDENTALCNC ‒A CNC application for machining
jobs and maintaining the machine.
To create and design the dental objects you also need
a CAD application (sold separately by specialist
dealers).
4.7 Anti-soiling concept
The anti-soling concept decreases the soiling and wear
of sensitive machine parts.
The anti-soiling concept does not replace the regular
cleaning of the machine. Without regular cleaning, the
machine life decreases significantly.
NOTICE Machine damage when dry
machining without an air
extraction system
When dry machining, an operational external air extrac-
tion system must be installed. Otherwise, the machine
will get soiled over time and become defective.
Always use a correctly installed and operational
external air extraction system during dry machining.
The anti-soiling concept consists of:
Dry machining
nThe external air extraction system ‒An
external suction unit creates a vacuum in the work-
ing chamber and extracts machining debris from
it.
nAir that is emitted into the working cham-
ber ‒Blows machining debris away from the
spindle and other machine parts.
nThe internal vacuum sensor ‒Constantly
monitors the vacuum in the working chamber.
nThe ionizer ‒The ionizer electrically discharges
machining debris of certain materials to reduce
their distribution in the working chamber.
Wet machining
The cooling liquid keeps machining debris away from
sensitive machine parts.

5.4 Establishing the electric con-
nection
NOTICE Damaging of the machine
through heavy voltage
fluctuations and power surges
Heavy voltage fluctuations and power surges can
disrupt the control unit and can cause system failures.
Connect the machine to a dedicated current circuit
or ensure that no devices are connected that can
cause heavy voltage fluctuation when switched on.
If heavy voltage fluctuations cannot be avoided,
install a surge protector that protects the machine
from heavy voltage fluctuations.
NOTICE Short-circuit hazard when the
machine is too cold
If the machine is transported from a cold environment
into a warmer environment, a short circuit may occur
caused by condensate.
Before switching on the machine after trans-
portation, ensure the following:
nThe ambient air has the allowed temperature.
nThe machine has the same temperature as the
ambient air. This will take at least 48 hours.
nThe machine is completely dry.
The machine requires a continuous power supply for
proper operation.
1. Plug the provided power cable into the power con-
nection at the connection panel of the machine.
2. If power failures occur regularly at the installation
location or if there are frequent voltage fluc-
tuations, install an Uninterruptible Power Supply
(UPS), type online/ VFI (IEC 62040-3, class 1).
If a power failure occurs during job execu-
tion, the tool may break and the blank may
be destroyed.
3. Insert the plug of the cable into a socket that is pro-
tected by a Residual Current Device/ Ground Fault
Circuit Interrupter.
5.5 Removing the transport lock
Before operating the machine for the first time, you
must remove the transport lock. The transport lock
prevents the spindle from getting damaged during
transport.
1. Ensure the following:
nThe machine is connected to the electrical
source.
nThe CAM computer is not connected to the
machine.
2. Switch on the machine at the main power switch.
3. Open the working chamber door.
4. Switch off the machine at the main power switch.
5. Remove the transport lock as shown in the sup-
plement.
