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 control 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.
If the shipment is incomplete or has suffered transport damage, you must notify the forwarder and Retsch
GmbH immediately (within 24 hours). Under certain circumstances, claims lodged at a later date may not
be considered valid.
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.
At a higher humidity, the electrical and mechanical components may be damaged, and performance data
changed to an unknown extent.
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.

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.

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
