1 PRODUCT DESCRIPTION 1.4 Conformity declaration The CE-mark is always set by the manufacturer. Precondition is the issue of a declaration of conformity according to Standard DIN EN 45014 in which the manufacturer declares the conformity of the product with all relevant EU directions.
1 PRODUCT DESCRIPTION 1.5 Initial Setup Before the first operation and after each rotor change, you have to select the appropriate rotor code. You can find each rotor type in the printed order number on the rotor. Example: Angle rotor 220.96 V01 ≙ Rotor type “96“ Swing out rotor 220.68 V04 ≙ Rotor type “68“ Switch on the unit and open the lid. Now press simultaneously the keys “lid “ (1) and “stop” (2). In the display “rpm/rcf” then appears the selected rotor type, ex. “96”.
1 PRODUCT DESCRIPTION 1.5.1 Access to the “Operating Data“ Mode In this mode you can check the following points: 1. 2. 3. 4. 5. 6. 7. Number of starts Operating hours of the centrifuge Software-version Error list Operation of imbalance sensor Operation of keyboard Display test If the centrifuge is still turned off, press simultaneously the keys “time“ (4) and “lid“ (1) and turn on the main switch of the centrifuge. Now release both keys again. As a result a display test is executed for approx. 5 seconds.
1 PRODUCT DESCRIPTION 1.5.2 Call up of operating data In the mode “Initial Setup“ you can call up the operating data of the centrifuge. Please proceed as described under point 1.5.1 to enter this program mode. Press the key “accel/decel“ (5). In the display “accel/decel“ flashes the word “service“.
2 OPERATION 2.1 Installation of rotors 2.1.1 Mounting and loading angle rotors Clean the drive shaft with a clean, grease-free piece of cloth. Place the rotor onto the drive shaft. (see photo 4) Be sure that the rotor is fully installed on the motor shaft. Photo 4 Photo 5 ATTENTION: For safety always ensure that rotor fixing screw is tightened before each run.
2 OPERATION Hold the rotor with one hand and secure the rotor to the shaft by turning the fixing screw (1) clockwise. (see photo 6). 1 photo 6 ATTENTION: For safety always ensure that rotor fixing screw is tightened before each run. (see photo 6) It is allowed to operate a 12-place-rotor with 2 or 4 loaded tubes only. But the loaded borings must be opposite each other.
2 OPERATION 2.1.2 Mounting and loading swing out rotors Clean the drive shaft with a clean and grease-free cloth. Place the rotor to the motor shaft. Be sure that the rotor is fully installed onto the motor shaft. Hold the rotor with one hand and secure the rotor to the shaft by turning the rotor screw (1) clockwise. The installation of the buckets and the adapters must be done appropriately photo 10.
2 OPERATION 2.1.3 Overloading of rotors The maximum load permitted for a rotor, which is determined by the manufacturer, as well as the maximum speed allowed for this rotor (see label on rotor), must not be exceeded. The liquids the rotors are loaded with, should have an average homogeneous density of 1,2 g/ml or less when the rotor is running at maximum speed.
2 OPERATION 2.2.2 Lid release Once the centrifuge lid is closed the display shows “rpm/rcf“ and “close“ (8). At the same time the preselected rotor type is indicated, ex.. “nr 96” (11). During the run you can call up the rotor type at any time by pressing the key “lid” (1). By pressing the key “lid“ (1) you can release the lid of centrifuge. As soon as the electronic lid is completely released, it appears the word “open“ (9). Now you can open the lid of the centrifuge.
2 OPERATION 2.2.4 Pre-selection of speed / RCF-value By pressing the key “rpm/rcf“ (6) the pre-selection of the speed is activated. By pressing the key once the word “rpm“ (12) flashes. By pressing the key once again the pre-selection of the centrifugal forces may be chosen. Flashing the word “rcf“ (13). You can set the desired values with the adjusting knob (7). In the display (14) the regulated value is shown permanently, before, during and after the run.
2 OPERATION 2.2.5 Pre-selection of running time The running time can be pre-selected in three different ranges from 10 seconds up to 99 hours 59 minutes. 1. Range from 10 seconds up to 59 minutes 50 seconds in steps of 10 seconds 2. Range from 1 hour up to 99 hours 59 minutes in steps of 1 minutes 3. Range continuous run “cont”, which can be interupted by the key “stop” (2). The running time can be pre-selected with the lid opened or closed.
2 OPERATION 2.2.6 Pre-selection of brake intensity and acceleration By pressing the key “accel/decel“ (5) this function is activated. By pressing the key once the word “accel“ (16) flashes in the display “acc/dec“. The desired acceleration can be pre-selected by the adjusting knob (7). The value 0 is equivalent to the lowest and the value 9 to the highest acceleration. By pressing the key “accel/decel“ (5) twice, in the display “acc/dec“ indicates the word “decel“ (17).
2 OPERATION 2.2.7 Starting the centrifuge After closing the lid you can start the centrifuge with the key “start“ (3). By pressing the key “start“ (3) you can start runs with manually pre-selected parameters. When the respective pre-selected running time has ended then the centrifuge will stop automatically or you can interupt the run in the mode “cont” with the key “stop” (2). 2 3 Photo 16 2.2.8 The „STOP“ key By the “stop“ key (2) you can interrupt the run at any time.
2 OPERATION 2.3 Safety features 2.3.1 Imbalance detection In case of the rotor not being equally loaded, the drive will turn off during acceleration. The rotor decelerates to stand still. When in the display “time” the word “error” together with the number “01” (18) appear, the weight difference of the samples is too huge. Weigh out the samples exactly. Load the rotor as described in chapter 2.1.1.
3 MAINTENANCE 3.1 Service and maintenance 3.1.1 Maintenance and cleaning Maintenance: Maintenance of the centrifuge is confined to keeping the rotor, the rotor chamber and the rotor accessories clean as well as to regularly lubricating the rotor insert bolts of a swing out rotor (If included). Vaseline, available in nearly each store, is the most suitable lubricant. The Vaseline must be free of resin and acids. Lubricants containing molycote and graphite are not allowed.
3 MAINTENANCE 3.1.2 Glass breakage With high g-values, the rate of glass tube breakage increases. Glass splinters have to be removed immediately from rotor, buckets, adapters and the rotor chamber itself. Fine glass splinters will scratch and therefore damage the protective surface coating of a rotor. If glass splinters remain in the rotor chamber, fine metal dust will build up due to air circulation.
4 TROUBLE SHOOTING 4.1 Error messages: cause / solution Preface: A description of the error messages are listed to help localize possible errors. The diagnoses referred to in this chapter may not always be the case, as they are only theoretically occurring errors and solutions. 4.2 Survey of possible error messages and their solutions 4.2.
4 TROUBLE SHOOTING 4.2.2 Description of the error message system The error message is shown in the "time" display through a two-digit number (19). At the same time the word “error” (20) is indicated in the display (see photo 20). 20 19 Photo 20 4.2.3 Error messages Errors that may be indicated in the LCD display: Error No.
