Summary of safety instructions – part 1
Failure to observe the values on the data plate can cause damage to the
electrical and mechanical components.
When sieves with a diameter of 400mm are used, only operate the AS400 to a maximum speed of 200
r.p.m.. Otherwise the sieve stack mass could create such large imbalances that the device slews out of
control in wild movements. Or fasten the AS400 as described in the chapter "Assembly".
Never start at the maximum speed of 300 r.p.m., but rather increase the speed slowly. When using sieves
with diameters from 400mm and the max. sieve stack, do not set the speed higher than 200 r.p.m.. Otherwise the masses set in motion too quickly can displace, causing the AS400 to tip over. Or fasten the
AS400 as described in the chapter "Assembly".
Ensure that the fabric of the sieve is not overstretched by overloading with sieving aids as this would have
a detrimental effect on the precision of your analytical sieve.
Do not clean the AS400 control with running water. Danger to life from electrical shock
Only use a rag moistened with water. Never use solvents.
These operating instructions do not contain any repair instructions. In the interests of your own safety,
repairs should only performed by Retsch GmbH or an authorised representative (service technician).

Technical specifications
Do not make any modifications to the machine and only use Retsch
approved spares and accessories.
The conformity to the European guidelines declared by Retsch
otherwise loses its validity.
It furthermore leads to the nullification of all warranty claims.
The AS400 control can cause major imbalances due to movements of
the material being screened. It must therefore be installed on a suitable bench in the laboratory. The net weight of the AS400 control is 73
kg.
Machine type designation:
AS400 control
Use according to the intended purpose
This machine is not intended as a production machine nor designed
for continuous operation, but rather as laboratory equipment intended for one-shift, 8-hour per day operation.
The RETSCH AS400 control is used for dry sieving with analytical
sieve shakers of up to 400 mm in diameter. The uniform, circular
horizontal movement of the sieve precisely separates the material
to be screened with a maximum grain size of 63 mm.
Fine and coarse grained materials, such as those used in milling,
brewing, chemicals, stonework, earthwork, wood and plastic industries, can be separated precisely with the AS400 control.
The circular horizontal movement of the sieve is particularly beneficial for separating certain products, such as milled grain, wood chips
and similar materials.
DIN 53477, for example, even specifies a circular sieve movement
for testing plastics (granular press masses).
The AS400 control can be deployed as test equipment for quality
control action under DIN EN ISO 9000 ff. The power frequency
independent control drive enables the AS400 control to supply
results reproducible anywhere in the world.
The speed/sieve plate acceleration and sieving time required are
set, displayed and monitored digitally. It is supplied with test certificate and can be calibrated. An arrangement to allow the direction
of turn to change at intervals can be linked in on request. Up to 9
sieve programs can be stored directly in the machine and called
up from there.
The AS400 control has an integrated interface to actuate all sieve
parameters via the EasySieve® software. The interface cable required for this is supplied as standard.

Emissions
The AS400 control can cause major imbalances due to movements of
the material being screened. It must therefore be installed on a suitable bench in the laboratory. The net weight of the AS400 control is 73
kg.
Characteristic noise values :
Noise measurement according to DIN 45635-031-01-KL3
The characteristic noise values are determined primarily by the set
amplitude width or sieve plate acceleration, the number of sieves
deployed and the nature of the material to be screened.
Example :
Sound power level LWA = 64 dB(A)
Workplace-related emission value L
= 58.4 dB(A)
pAeq
Operating conditions :
Material to be screened = quartz sand, grain size <1mm, 5 sieves
speed = 150 rpm
Maximum loading
Max. quantity of material to be screened = 5 kg,
max. sieve stack mass = 15 kg.
It should be noted that, despite an integrated counterweight, work
cannot be performed at 300 r.p.m. in every case. The large imbalance of, for example, 6x 400-type sieves, can cause the AS400 to
move on the laboratory bench.
At a maximum sieve stack mass of >10 kg, we recommend that
200 r.p.m. should not be exceeded.
Protection systems
IP54 or IP20 around the sieve carrier passage
Equipment dimensions
Height: up to approx. 850 mm, Width: 540 mm, Depth : 507 mm
Weight: approx. 73 kg without sieve stack and
without sieve clamping device
Base area required
540 mm x 507 mm; no safety clearances required.
06.11.2012 Retsch GmbH 9
Transport and assembly
Please retain the packaging for the duration of the warranty since, in case of a complaint, returning in unsuitable packaging can jeopardize your warranty claims.
During transportation, do not subject the AS400 con-
trol to impacts, jolts or vibrations. The electronic and
mechanical components could otherwise be damaged.
In case of wide temperature fluctuations (during shipment by air, for instance), protect the AS400 control
from condensation. The electronic components could
otherwise be damaged.
When the ambient temperature exceeds or falls below that
specified, the electrical and mechanical components may be
damaged, and performance data changed to an unknown
extent.
Packaging
The packaging used is selected with the shipping mode in
mind. It complies with the generally applicable packaging
guidelines.
Transport
Whilst transporting the AS400 control to the final place of
assembly after unpacking, ensure that the AS400 control
is only held by the underside of the sheet metal housing.
The plastic front is not suitable for this purpose.
Temperature fluctuations
Intermediate storage
Ensure that the AS400 control is stored in a dry place,
including intermediate storage.

unknown extent.
Assembly
SS A
Install the AS400 only on a stable laboratory bench to avoid
unpleasant transmission of vibrations.
Remove the hex bolts SS with an open-ended spanner
Remove metal sheets A (transport fastening)
You can leave the two metal sheets mounted if you wish to fix
the AS400 control to the laboratory bench.
The metal sheets can be used for individual fastening.
The AS400 control can cause major imbalances due to movements of
the material being screened. It must therefore be installed on a suitable bench in the laboratory.
We recommend that the speed set should not exceed >200 r.p.m. or
that the AS400 be fixed to the laboratory bench with metal sheets A
if the analytical sieves used are 400mm and have high sieve stacks.
The net weight of the AS400 control is 70 kg.
Alignment

The AS400 control is suitable for use with analytical sieves with
outer diameters of 100 / 150 / 200 / 203(8“) / 305(12“) / 315
and 400mm.
A variety of clamping units and covers are available for this purpose (see the accessories listing).

whereby pressing the red lever upwards allows the clamping
cover to move. The green levers remain in their initial position.
Slide the clamping cover down to the top sieve
Press the green lever downward several times, whereby the
red lever may not be moved.
the sieve cover can now be slid upward.
If, after the sieving process, the red lever proves difficult to
move, press the green lever and the red lever simultaneously for
a short time to release the tension.
We recommend the use of talcum powder if the base pan sticks
to the smooth surface of the sieve carrier when removing the
sieve stack.
When using the comfort sieve clamping unit, we recommend
that the mounting rods are cleaning from time to time. In addition, the comfort sieve clamping unit produces unavoidable
clamping notches on the mounting rods after a certain period of
time, which can hinder secure clamping.
It is therefore necessary to examine the mounting rods at regular intervals for notches in the clamping area, and then turn
them through 90°, if required. Use a 17mm open-ended spanner
for this purpose.
Turning the mounting rods:
Release lock nut KM.
Turn the mounting rods through 90°.
Retighten the lock nut securely.
If turning the mounting rods through 90° does not produce any
notch free areas, we recommend that the mounting rods be replaced.

Retsch analytical sieves
The new RETSCH sieves are initially available in the three design
models intended for sophisticated laboratory analysis:
200 x 25 mm
200 x 50 mm
203 x 50 mm = 8“ x 2“
They are, of course, compatible with other standardised sieves.
The new sieves are compatible with the rest RETSCH's range and
can also be combined with articles from most other manufacturers without problem.
Other significant benefits:
Each sieve leaves our factory with a works' certificate or – on
request – with a special acceptance test certificate as per DIN
ISO 3310-1.
Calibration certificates guarantee an even higher statistical security and show how we strive for perfection.
1. Sieve frames "from one mould" and seamless fabric transition
prevents cross-contamination (no solder or residues etc.)
2. Highly resistant to corrosion and easy to clean because of the
high alloyed stainless steel used (316L / 1.4435)
3. 15% lighter than traditional sieves whilst simultaneously offering
a larger free sieving area
4. Exemplary product quality due to fully automated production and
constant optical inspection
5. Innovative resistance welding technology guarantees perma-

Sieve accessories
RETSCH certificates
Before being delivered, each
sieve is optically gauged and
provided with a works' certifi-
cate.
On request, you receive a protocol with the acceptance test
certificate which documents
the measurement results in
tabular form and in graphics, or
a calibration certificate with
more detailed statistics.
Calibration service
As a special service we
offer to calibrate your analytical sieve. In doing so,
we record all the relevant
information for the sieve
according to standardised
gauging methods, and
confirm these in the requested certificate.
There are base pans, base pans with discharge, intermediate pans,
intermediate rings and sieve covers available which are compatible
with the different analytical sieves. Sieving aids and sieve stands
complete the range of accessories.
Please refer to our price list for details on how to order the analytical sieves and the other available accessories.

Working instructions
Sieving aids
When dealing with material that is difficult to separate, we recommend the additional use of sieving aids in the individual sieve fractions. Depending on the width of the sieve meshing and the preselected vibration intensity, pearls made of agate, rubber, porcelain or
nylon bristles and Vulkollan cubes may be used. Also refer to the
table below.
Refer to the paragraph on sieving material quantities for the recommended material volume.
Sieving material quantities
The sieve stack required for sieve analyses is composed of analytical sieves arranged one above the other, with progressively larger
holes towards the top, plus the base pan.
To ensure fast separation with exact results, the quantity of the
material to be screened should be adapted to the sieve diameter
and the nominal size of the openings.
The relevant standards on sieve analysis (e.g. DIN 22019 / part 1)
state guideline values in which the following maximum charge
quantities are recommended:

EasySieve
EasySieve, the software package from RETSCH for grain
size analysis, is superior to manual evaluation in many
respects. This is because the software is able to perform
the required measuring and weighing processes automatically – from determining the weights of the sieves to
evaluating the data. And in a much more simple and comfortable manner – thus making life easier.
The software is structured in a self-explanatory way and
follows the logical chain of events involved in analysing
grain sizes. This makes it possible to use it with confidence
in a fairly short time. The multiplicity of evaluation options
additionally provides the utmost flexibility in adapting to
demanding, individual applications.

The AS400 control can be connected to the serial interface of a
personal computer for the purpose and transmitting and receiving data. This is done with the normal 9 pole RS232 cable supplied as standard with the AS400 control. This makes it possible to communicate with the EasySieve® evaluation software
available as an accessory.
