Safety
We herewith exclude any kind of claim relating to personal
injury or material damage arising from a failure to comply with
the following safety instructions.
The AS 200 tap is a very modern highly efficient product
manufactured by Retsch in accordance with the latest technical
developments. It is completely safe if used for its intended purpose
by operators familiar with this technical documentation.
Safety instructions
You, as the owner / managing operator, must ensure that
the people entrusted with working on the AS 200 tap:
have read and understood all rules relating to safety,
have familiarised themselves before starting work with all
the handling instructions and the regulations for the target
group of relevance to their work
have easy access at all times to the technical
documentation for this machine
new personnel must be familiarized with the safe and
appropriate handling of the machine before beginning
work on the AS 200 tap, either by verbal instruction from
a competent person and/or through this technical
documentation
Incorrect operation can result in personal injuries and
damage to equipment. You are responsible for your own
safety and that of your staff.
Make sure that no unauthorised person has access to the
AS 200 tap.
For your own protection have your staff confirm that they
have been instructed in the operation of the AS 200 tap.
You will find a draft of a suitable form at the end of the
section on safety.

Summary of Safety Instructions
We herewith exclude any kind of claim for personal injury or material damage arising from a failure to
comply with the following safety instructions.
Do not make any modifications to the machine and use only spare parts and accessories approved by
Retsch. Otherwise, the Declaration of Conformity to the European Directives declared by Retsch will lose its
validity and you will forfeit any right to claims under guarantee.
Please keep the packaging for the duration of the guarantee period because returning the equipment in
unsuitable packaging if you have a complaint can jeopardize your guarantee claims.
The AS 200 tap may not be knocked, shaken or thrown about during transport as this could damage the
electronic and mechanical components.
If the AS 200 tap is subjected to a high level of fluctuations in temperature (e.g. during shipment by air) it
must be protected from condensation in order to prevent damage to the electronic components.
If the shipment is incomplete and / or has been damaged during transport, you must notify the forwarder
and Retsch GmbH immediately (within 24 hours). Complaints lodged at a later date might not be considered
valid.
If the temperature drops below or exceeds the range for ambient temperature, the electrical and mechanical
components may become damaged and performance data may change to an unknown extent.
At high air humidity the electrical and mechanical components can become damaged and performance data
can change to an unknown extent.
To ensure reliable operation, the AS 200 tap must be doweled firmly to the underlying surface by means of
the transport angle piece.
Non-adherence to the levels specified on the type plate can damage electrical and mechanical components.
Ensure that the sieve mesh is not stretched excessively by overloading with sieving aids because this would
impair the precision of your analytical sieves.
The sieves may not be overloaded. Overloading destroys the sieve mesh and impairs sieving results.
The AS 200 tap may not be cleaned with running water. Risk of a fatal electric shock.
Use only a cloth moistened with water. Solvents are not permitted.
These operating instructions do not include repair instructions. For your own safety, repairs may be done only
by Retsch GmbH, an authorised agent or Retsch service technicians.

Technical Data
Do not make any modifications to the machine and use only
spare parts and accessories approved by Retsch.
Otherwise the Declaration of Conformity to the European
Directives declared by Retsch will lose its validity.
Furthermore you will forfeit the right to any kind of
claims under guarantee.
The movement of the sieved material in the AS 200 tap can
cause considerable unbalance. It must therefore be installed on
a suitable laboratory table. The net weight of the AS 200 tap
is 68 kg.
Machine type designation: AS 200 tap
Use in accordance with the intended purpose
This device is not designed as a production machine or for
continuous operation, but as laboratory apparatus for
single-shift 8-hour operation.
The RETSCH AS 200 tap is used for dry sieving with
analytical sieves with diameters of up to 203 mm, whereby
the uniform, horizontal circular sieving motion and the
tapping pulse ensure an exact separation of the material
being sieved with a feed grain size of up to a max. 25 mm.
Fine and coarse grained materials, such as those produced
in mills, breweries, and in the chemicals, stone, earth,
wood and plastic industries can be separated exactly with
the AS 200 tap.
The horizontal, rotating movement of the material being
sieved is particularly advantageous for separating products
such as milled grain, wood chips or similar materials.
Accordingly, DIN 53477, for example, specifies a rotating
sieve motion for testing plastics (grainy moulding plastic
material).
The AS 200 tap can be used as testing equipment for
monitoring quality conformance to DIN EN ISO 9000 et
seq.
The required sieving time is digitally set, displayed and
monitored.
The AS 200 tap has an integrated interface for triggering all the
sieving parameters through the EasySieve® software. The
interface cable required for this is included in the scope of supply.

Emissions
Noise characteristics:
Measurement of noise in accordance with DIN 45635-031-01-KL3
The noise characteristics depend on the set amplitude or sieve
base acceleration, the number of sieves and the type of the
material being sieved.
Example 1:
Workplace-related emissions LpAeq = = 79 dB(A)
Operating conditions :
Sieved material = quartz sand, grain size <1mm, 5 sieves
Example 2:
Workplace-related emission level LpAeq = 65 dB(A)
Operating conditions :
Sieved material = quartz sand, grain size <1mm, 5 sieves
With noise insulating hood
Maximum loading
max. sieved quantity of sieved material = 3 kg
max. weight of a sieve stack = 6 kg
max. height of a sieve stack: 6 sieves (50 mm) + 1 collecting base
(50 mm)
Systems of protection
IP 54 and IP 20 resp. in the area of the sieve holder passage
Device dimensions
Width: 715 mm, height: approx. 760 mm, depth: 520 mm
Weight: approx. 92 kg (without sieve stack)
Required standing area
800mm x 550mm; no safety spacing needed.
Technical data
Number of oscillations of the sieve plate: 280/min.
Number of tapping pulses: 150/min.

Transport and Installation
Please keep the packaging for the duration of the
guarantee period because returning the equipment in
unsuitable packaging if you have a complaint can
jeopardize your guarantee claims.
Lifting above head height is not permissible!
The AS 200 tap may not be knocked, shaken or
thrown about during transport as this could damage the
electronic and mechanical components.
If the AS 200 tap is subjected to a high level of
fluctuations in temperature (e.g. during shipment by
air), it must be protected from condensation in order to
prevent damage to the electronic components.
If the temperature drops below or exceeds the range for
ambient temperature, the electrical and mechanical
components may become damaged and performance data
may change to an unknown extent.
