Safety The AS 200 tap is an ultra-modern, highly efficient product of Retsch GmbH, corresponding to state of the art. If the machine is used according to the intended purpose with a knowledge of this technical documentation it is completely safe and reliable to operate.
Safety instructions – summarised, part 1 Safety instructions We exclude any claims for damages of any kind for injury to persons and damage to equipment arising from non-observance of the following safety instructions. Use according to the intended purpose Do not make any alterations 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.
Safety instructions - summarised, part 2 Sieving aids Ensure that the sieve fabric is not expanded excessively through overloading with sieving aid, since this will impair the precision of your analytical sieves. Quantities of material to be sieved The sieves must not be overloaded. Overloading destroys the sieve fabric and impairs the sieving results.. Cleaning The AS 200 tap must not be cleaned with running water. Danger to life through current surge. Use only a cloth moistened with water.

Technical data Machine type designation: AS 200 tap Use according to the intended purpose This machine is not designed as a production machine or for continuous operation, but as a laboratory apparatus intended for 8 hour single-shift operation. The RETSCH AS 200 tap is used for dry sieving with analytical sieves of diameter up to 203 mm.
Emissions Noise charateristic values: Noise measurement according to DIN 45635-031-01-KL3 The noise characteristic values are influenced by the set amplitude or sieve bottom acceleration, the number of sieves clamped and the type of sieved material.
Transport and Installation Packing Packing is adapted to the transport route and conforms to the generally applicable packing guidelines. Please keep the packing material for the duration of the guarantee period since if there is a complaint and the machine is returned in inadequate packing your guarantee claim will be at risk. Transport After unpacking the AS 200 tap is to be lifted and transported only by the transport screws TS supplied with the machine. Fig. 1 Net weights: AS 200 tap approx.
At higher atmospheric humidity the electrical and mechanical components can become damaged and performance data are changed to an unknown extent. Installation height: Max. 2000 m above sea level Installation Install the AS 200 tap only on a stable, safe subsurface. Otherwise undesirable vibrations can be transmitted. Alignment To ensure that the AS 200 tap has a reliable standing position all 4 feet must be in contact with the installation surface.

Connect Safety Device When installing the AS 200 tap, special attention must be paid to mounting the protective devices correctly in order to meet the requirements of the harmonised EN292-1 standard. Depending on the safety device selected either the PS safety plug can be fitted or the local safety devices can be connected with the aid of the safety socket. Make sure that if the PS safety plug is being used on its own the operator is protected from any inadvertent reaching into the machine.
Operation of the AS 200 tap Switching on and off The main switch is located on the rear left side of the AS 200 tap Switch on the main switch -- lights up in the display time min The LED STOP lights up The AS 200 tap is now without an interval and is ready for functioning in continuous operation at a speed of 50 min-1. Display and operating element The button + increases the sieving time in the range f rom 1 – 99 min.
Starting – Interrupting - Stopping Starting: Press START / button 15 and M simultaneously Green LED over button 15 lights up Interrupting (pause function): 15 Press STOP / button 16 once Red LED over button 16 lights up Values remain visible Press START / button 15 and M simultaneously Sieving process is continued 16 Stopping (stand-by function): Press STOP / button 16 twice Red LED over button 16 lights up The complete display is extinguished Activate displays = press button 15 once New values can now
Removing the sieve stack To remove the sieve stack lift this slightly, together with the lid, and at the same time press the tapping arm upwards. Withdraw the sieve stack forwards. Switching off the TAP function B Pull out the stop bolt B and turn this. The tapping arm A now locks into place when this is lifted into the top position. A The AS 200 tap now works as a plane sieving machine. 08.01.2008 Retsch GmbH 17 Doc.Nr. D 98.025.
Retsch Analytical Sieves Analytical sieves of diameter 200 and 203 mm To begin with the new RETSCH sieves are available in the three different types which are most important for sophisticated laboratory analysis: 200 x 25 mm 200 x 50 mm 203 x 50 mm = 8“ x 2“ Compatibility with other standard sieves is of course guaranteed. The new sieves are compatible with the standard range of RETSCH sieves and can be combined with most other sieve makes without problems.
Working Instructions Sieving aids For materials which are difficult to separate we recommend the additional use of sieving aids in the individual sieve fractions. For this purpose balls of agate, rubber, porcelain or nylon brushes and Vulkollan cubes can be used, depending on the mesh size of the sieve and the preselected oscillation intensity. See also the table below.
EasySieve Control, evaluation, documentation EasySieve , the software for grain size analysis from RETSCH, is far superior to manual evaluation in many respects. This is because the software is able to carry out the measuring and weighing operations automatically – from registering the weights of the sieves up to evaluation of the data. This can be accomplished more easily and more conveniently than ever before – hence „easy“.
General Cleaning For thorough, careful, time-saving cleaning of your analytical sieves we recommend Retsch ultrasonic baths. Please ask for our special leaflet „Care and Cleaning of Analytical Sieves“, which is free of charge. Do not clean the AS 200 tap under running water. Danger to life through current surge. Use only a cloth moistened with water. Solvents are not allowed. Maintenance The AS 200 tap is essentially maintenance-free.
