Safety
Target group: Everyone who deals with the
machine in any manner
whatsoever.
The AS200 is a modern, high-performance product
manufactured by the Retsch GmbH; it incorporates the
latest technology. It is entirely safe in operation when
used for the intended purpose and in accordance with
the present technical documentation.
Safety notes
You, as the owner/operator, must ensure that persons
who are entrusted with the operation of the AS200.
* have read and understood all the regulations included in the
chapter on safety,
* have made themselves familiar, prior to starting work, with all
the operating instructions and regulations for the target groups
relevant to them,
* have complete, immediate and unrestricted access to the
technical documentation for this machine,
* new personnel shall have been made familiar with safe and
appropriate use of the AS200 before starting work with the
machine, through instruction by a qualified person and/or with
the help of the present technical documentation.
* Incorrect operation can result in injuries to persons and
damage to property. You bear responsibility for your own
safety and for that of your co-workers.
* Ensure that no unauthorized persons have access to the
AS200.
For your own protection, have your co-workers certify in
writing the fact that they have received instruction in the
operation of the AS200. A suggestion for a printed form
which can be used for this purpose will be found at the
end of the chapter on safety.
We reject herewith any and all claims in conjunction with
personal injury or property damage resulting from failure
to observe the following safety instructions.

Technical specifications
Do not make any modifications to the machine and use only
RETSCH approved spares and accessories.
Failure to comply will invalidate the CE declaration and
guarantee.
Machine designation: AS200
Utilization in accordance with the intended
purpose
The AS200 is suitable for both dry and wet sieving of
free-flowing, dispersed products where the input product
exhibits grain size of up to a maximum of 25 mm.
Emissions
Characteristic noise values :
Noise measurement according to DIN 45635-31-01-KL3
The characteristic noise values are determined primarily
by the set amplitude value, the number of test sieves
and the characteristics of the sieving material.
Example 1 :
Sound power level: LWA = 71 dB(A)
Workplace-related emission L
Operating conditions:
Sample material: quartz, grain size < 1 mm, 5 sieves
vibration height : 1,5 mm
Example 2 :
Sound power level: LWA = 76 dB(A)
Workplace-related emission L
Operating conditions:
Sample material: quartz, grain size < 1 mm, 5 sieves
vibration height : 3 mm
= 63 dB(A)
pAeq
= 67 dB(A)
pAeq
Electromagnetic compatibility (EMC)
Strong electromagnetic interference fields, such as highpower radio transmitters, can have an adverse influence
on amplitude control in the AS200 model.
Once the source of interference is eliminated, the
AS200 will return to normal operation (self-correction).
Electrical protection class
IP54 and IP20 in the area of the sieve carrier passage.
Equipment dimensions
Height:: up to about 800 mm
Width: 400 mm , Depth: 400 mm
Weight: approx. 40 kg without sieve stack and
without sieve clamping device
Footprint
400 mm x 400 mm; no safety clearances required

Shipping and installation
Please retain the packaging for the duration of the
warranty since, in case of a claim, returning in unsuitable
packaging can jeopadize your warranty entitlements
During transportation the AS200 may not be subjected to
impact or vibration; it must not be thrown. The electronic
and mechanical components could otherwise be
damaged.
In case of wide temperature fluctuations (during shipment
by air, for instance) the AS200 will have to be protected
against condensation; the electronic components could
otherwise be damaged.
When the ambient temperature exceeds or falls below that
specified, the electronic and mechanical components may be
damaged, and performance data changed to an unknown
extent.
At higher humidity, the electronic and mechanical components
may be damaged, and performance data changed to an
unknown extent.
Target group: Owner, freight forwarder, operator
Packing
The type of packaging used has been selected in
accordance with the shipping mode. It complies with
generally applicable packaging guidelines.
Shipping
Temperature fluctuations
Intermediate storage
Also ensure that the AS200 is stored in a dry place.
Requirements for the installation site
Ambient temperature
5°C to 40°C
Humidity:
Maximum relative humidity 80% at temperatures up to 31°C;
linear decline down to 50% relative humidity at 40°C.
Installation site – altitude:
max. 2000 m above mean sea level
Installation / Shipping nuts
31.07.2012 Retsch GmbH 7
SM
Set up the AS200 only on a stable laboratory bench to avoid unpleasant transmission of vibrations.
Loosen the hexagonal nuts SM using an open-ended
spanner until the sieve plate moves freely
Unscrew the wing screws A (shipping nuts) with hexagonal
nuts.
Mount the appropriate sieve clamping device (See the
chapter on operation for instructions)
Keep the wing screws A with hexagonal nuts (shipping nuts)
in a safe place for later transportation.
Reusing the shipping nuts
Screw the hexagonal nuts fully onto the wing screws
Screw the wing screws through the sieve plate into the
housing
Twist the hexagonal nuts downwards and tighten until the
sieve plate can no longer move
Operation with these shipping nuts in place, or shipping without
the these nuts installed, could cause damage to mechanical
components.
Electrical connection
Failure to observe the values on the data plate can cause
damage to either the electrical or the mechanical components or both.
* Refer to the data plate for information on the voltage and
frequency at which the AS200 is to be operated.
* Ensure that the values shown there correspond to those for
the local power supply.
* Use the supplied power cord to connect the AS200 to the
power supply.
* When connecting the power cord to the power source, be sure
that the supply circuit is fused in accordance with local codes.
