This will help you to avoid mistakes and thus damages. This consists of: speed controller and stabiliser control for soft-start fuse protection approx. Taking into operation Make sure that the electric voltage of the instrument and the power supply correspond Do not use this instrument in hazardous area.
The POLYTRON PT is not designed for continous working The recommended maximal uninterrupted working time should not exceed 20 minutes POLYTRON dispersion aggregates must never run without liquid the lower slide bearing is cooled and lubricated by the liquid phase of the treated medium Make sure that the dispersion aggregates are properly cleaned after every use Never touch a spinning rotor, nor shaft, nor the motor side coupling parts Working with high speeds makes it possible that a noise of 85 dB A is exceeded.
The user shall undertake necessary steps for protection. Before taking the instrument into operation the separately supplied support rod has to be installed on the backside of the drive motor. The necessary key is supplied as well. Make sure that the rod is properly fixed. It is recommended to run new aggregates in water for approx.
The connection of aggregates is effected without tools by a safety quick-coupling. The aggregate has to be inserted into the motor-side coupling and slightly turn into ist correct position only until you hear a clear click. For de-connection of the aggregate simply press the coupling ring towards the front and pull the aggregate off. When moving the coupling ring the aggregate can fall off the coupling. Hold the dispersing tool when de-coupling and avoid injury of recipients, stand or working bench.
They are manufactured in a variety of different forms and recommended according the dispersion problem. Please see the actually valid price list for detailed order codes. In addition to that, they can be sterilised as per all standard methods, also autoclaved. This material convinces by ist extraordinary chemical resistance and mechanical characteristics.
All aggregate are equipped with saw-teeth which efficiently accelerate the precutting out your sample material. The stator teeth are connected to each-other by a safety ring what avoids their bending also if working with hard and high viscous materials. The optimal immersion depth of the aggregate is approx. The lower edge of the lower cleaning hole has to be immersed.
B inclined immersion in an angle of approx. The maximum immersion depth is approx. POLYTRON dispersion aggregates must not be used dry the lower slide bearing is cooled and lubricated by the liquid phase of the treated medium At certain rotor speeds, depending on viscosity and volume of the treated medium, resonances and vibrations may appear.
Please avoid these delicate speeds. Make sure that the dispersion aggregates are properly cleaned after every use Never touch a spinning rotor, nor shaft, nor the motor side coupling parts Never let a POLYTRON-aggregate touch the bottom of the vessel.
Drive and control electronics are in the same housing. As first step please check the mains and run a test with no aggregate by switching ON the main switch on the front of the drive. The speed is selected by the control knob on the left side from front of the drive motor. Depending on product different individual speeds are optimal.
The speed is reduced in case of increasing viscosity in order to protect the drive from overload. Is the viscosity to high, the motor is stopping automatically. An electronic control system avoids injury of the motor drive. Page 9 von Is the motor overloaded the power supply is cut-off automatically. In this case switch off the main switch to 0, disconnect the aggregate and re-start the instrument as fast as possible, without load, in order to accelerate cooling by the built-in fan.
Often release of the overload fuse indicated a general overload of the instrument. The motor needs no maintenance. There are no serviceable parts inside which can be repaired by the user.
The only exceptions are the carbon brushes. We recommend service and repairs to be done by specialised staff of our Authorised Service Centres only Use approved original spare parts only.
The replacement of the carbon brushes can be effected after disconnection of all electric supplies. The motor housing has to be opened. Fix the knob with one hand and carefully release the centric screw. Remove the upper part of the housing 3 by relaeasing the Philips screw 4 Remove the carbon brushes 5 with adequate tool and replace both.
Use approved original spare parts only and exchange carbon brushes pair-wise Remount housing part and control knob Take the drive into operation as per this instruction manual and let it run at low speed during approx. If strong sparking occurs, relieve or switch off motor and exchange carbon brushes, otherwise the collector can be damaged. Distribution amplifier, 18 dB.
