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

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.

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.

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 LpAeq = 63 dB(A)

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 LpAeq = 67 dB(A)

Operating conditions:

Sample material: quartz, grain size < 1 mm, 5 sieves

vibration height : 3 mm

Electromagnetic compatibility (EMC)

Strong electromagnetic interference fields, such as high-

power radio transmitters, can have an adverse influence

on amplitude control in the AS200 control model.

Once the source of interference is eliminated, the AS200

control 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 kgwithout sieve stack and

without sieve clamping device

Footprint

400 mm x 400 mm; no safety clearances required

Shipping and installation

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.

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

Shipping

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.

Temperature fluctuations

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.

Intermediate storage

Also ensure that the AS200 is stored in a dry place.

Standard equipment

* AS200

* 1 line power cord

* 1 serial connector cable, PC-to AS200

* 1 copy of the operating instructions

Check to ensure that the shipment is complete and

includes any accessories which you may have ordered

separately.

Verify that the AS200 operates perfectly (see in this

regard the chapter on operation).

If the shipment is not complete or is damaged, you

must notify the forwarder and Retsch GmbH

immediately (within 24 hours). Under certain

circumstances compensation cannot be paid for

claims which are lodged later.

21.11.2001 Retsch GmbH 8 Doc. No E98.014-016.9999 A

Requirements for the installation site

Ambient temperature

5°C to 40°C

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.

Humidity:

Maximum relative humidity 80% at temperatures up to 31°C;

linear decline down to 50% relative humidity at 40°C.

At higher humidity, the electronic and mechanical

components may be damaged, and performance data

changed to an unknown extent.

Installation site – altitude:

max. 2000 m above mean sea level

Installation / Shipping nuts

Set up the AS200 only on a stable laboratory bench to avoid un-

pleasant 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 Awith 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.

21.11.2001 Retsch GmbH 9 Doc. No E98.014-016.9999 A

Electrical connection

* 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.

Failure to observe the values on the data plate

can cause damage to either the electrical or the

mechanical components or both.
