1.1 Open gate cap and install rotor.

1.2 Centrifugal pipe and pipe carrier after adding in sample are placed

symmetrically in the rotor.

1.3 Press swith of power supply after shutting off gate cap.

1.4 Speed display the button below, Press the "+" or "-" adjustment speed parameter, speed setting range: 0~4000 r/min

1.5 Time display the button below. Press the "+" or "-" adjustment centrifuge elapsed time, time setting range: 0~99 r/min

1.6 Press stop key to stop the machine operation. Gate cap can only opened when speed is reduced to zero(o). First of all, Press the white button ,On the left side of the top. Hold down the white button. the door with the hand cover open up.

1.7 Fetch sample to prepare for next separation.Repeat above mentioned operation process.

1.8 Shut off power supply after finishing test.

1.9 During Power fåilure. pull of open gate cap below the instrument in rotor running stopping completely and no risk to open gate.

2 Driving system use direct driving of brushless motor with sealing prelubricated driving shaft, and special vibration damper greatly reduces vibration and noise. Note: It appears that produces sotne vibration under critical speed (roughly between 400r/min and 900r/min) . This vibration is a normal phenomenon. Unbalanced detector sends the motor to stop running when producing abnormal vibration.

Fig.2 Drive mechanism

Electric control system

Electric control system states microcomputer controlling for speed, temperature and centrifugal time. Speed and temperature are displayed with numerical code. The centrifugal is displayed according to different rotors, and stated at the same time.

Safe protective device

Overspeed protective device

Motor generates automatically power-off when speed is out of control or exceeds 500r/min to prevent overspeed running of the machine so that protecting safety of the machine and personnel.

Unbalance protective device

Owing to unbalance running, the machine produces the vibration. Faullamp lights, then motor is power off and the machine stops running when amplitulde exceeds provided value.

Maintenance
Painting a few grease or lubricating-oil to prevent rusting and easy to

install and remove the rotor.
Conduct mgtllar cheek whether the rotor is of the erosion and

haircrack. Check before use is a more important. Pay attention to renewal of the centrifugal tube.
When the rotor is not used over a long period of time, place it in dry

-ing place without erosion to prevent the erosion to prvvent the erosion and rusting.
Quality Guarantee Period for the rotor
Rotor installation

Clean the rotor base in the centrifügal chamber and the bore of the rotor body with clean flannelette and paint thin grease. and lift the rotor with hands and place on the rotor base in the centrifugal chamber, Rotor boreis inserted firmly on the rotor base and screw down with bolt.

Proper use of the rotor
The rotor should conduct the use and running according to stated speed.
Clean the centrifugal cup before use and place the test solution after weighing in the centrifugal cup. Weighing error of the test solution is less than If the centrifugal test sample is few. then divide the test solution into a half or one fourth on the average. and place symrnetrically test solution after weighing in the centrifugal cup. and fill the water or other solution in the rest empty cups and place them symmetrically after symmetrically after weighing. The centrifugal cup running must be in the same time for every running. Strictly forbid the centrifuge running when the centrifugal cup or test solution is unsynmetrically placed. Abnortnal use of the centrifugal cup may produce strong vibration and even datuage the machine and
danger staff sale.
Maintenance of the rotor

Check regularly the oxidation layer of the inside and outside face of

the rotor and the centrifugal cup. If there exist the peeling. erosion, critical sculling or haircrack.then should stop to use.

Clean the residual liquid or water of the inside and outside face of the rotor and the centrifugal cup with clean flanneled. and dry by airing for stand-by application after completion centrifugal work.

Prevent the rotor come into collision with the centrifugal cup each other when application rotor and centritilgal cup.

Need not to use the rotor and the centrifugal cup should be take out from the centrifugal chamber and place in dry place.

Attention matters for safe operation

Take out the foreign matter from the cavity of the centrifugal chamber before use centrifuge.

Strictly forbid that running speed of the rotor exceeding rated speed.

Strictly forbid unbalance running.

The rotor should be installed firmly on the rotor base.

Strictly forbid to open the cap of the centrifugal chamber when the centrifuge is running.

Strictly forbid to touch the rotor in running with hand.

Strictly forbid to high-speed running without the rotor.

Various rotors matched for the machine are of operating life up to five (5) years i.e quality guarantee period of the rotors are of five years.

Quality guarantee period of the rotor is calculated from the day to leave factory. tched rotor can produce corrosion spot and crack in low-speed state. There for rictly forbid to use the rotor with the erosion and crack. Guarantee period of the tor is not suited for etched and split rotor.
