EN-7 FrontierTM Centrifuge FC5714/FC5718/FC5718R/FC5816/FC5816RFigure.13 WRONG Figure.14 CORRECT3.1.4 Loading and overloading of rotorsAll approved rotors are listed with their maximum speed and maximum filling weight in "table 2 permissible netweight" (See APPENDIX).The maximum load permitted for a rotor, which is determined by the manufacturer, as well as the maximum speedallowed for this rotor (See label on rotor), must not be exceeded. The liquids the rotors are loaded with should havea maximum homogeneous density of 1.2 g/ml or less when the rotor is running at maximum speed.In order to spin liquids with a higher density, the speed has to be reduced according to the following formula:Reduced speed nred = √ 1,2ℎ𝑖𝑔ℎ𝑒𝑟 𝑑𝑒𝑛𝑠𝑖𝑡𝑦 x max. speed (nmax) of the rotorExample:nred = √ 1,21,7 x 4.000 = 3.360 rpmIf in case of any questions, please contact the manufacturer!To determine the relative centrifugal force(RCF/G-force) for a specific adapter, you can calculate per DIN 58 970using the attached formula:RCF = 1.117862*10－5*n2*rmaxn: revolutions per minute (RPM)rmax: max centrifuging radius in cm by using the bottom of tubes3.1.5 Removing the rotorUntighten the rotor fixing nut completely (screw over the stiff point) and lift the rotor vertically out of the centrifuge.(See figure 9 and 10).3.2 Lid control3.2.1 Lid openAfter the run, when the lid of the centrifuge is closed, the word "close" (M1) appears in the display "RPM | RCF"(A-1). Additionally, if there is a rotor in the centrifuge, the word "rotor"(M3) appears as well as the code number ofthe respective rotor, which is in the centrifuge system "71" (M4). If there is no rotor in the centrifuge, the word"rotor" (M3) flashes and additionally the word "no" (M4) appears. By pressing the key "Door Open" (7) you canrelease the lid of the centrifuge. As soon as the electromagnetic lid is completely released, the word "open" (M2)appears. Now you can open the lid of the centrifuge.Please refer to figure 15 below for reference.
