Page 5: General Product Description
Marathon series units are low-speed, general purpose centrifuges, used in medical, industrial, and scientific applications. The Marathon 3000 Series is available in two models: ventilated (3000) and refrigerated (3000R). Sections of this manual that apply to the refrigerated version will be designated 3000R or refrigerated only. -
Page 6: About This Manual
The Marathon Series features a maintenance-free, brushless motor, and an easy-to-use front panel, which provides three versatile timing modes: automatic timed run, short spin (momentary), and hold (continuous mode). Acceleration and brake rates may be controlled, to optimize runs: rapid for fast separations or slow for delicate samples. -

Page 16: Section 3 - Operation
3 Operation Rotor and Accessories A balanced load is essential for all centrifuges. An unbalanced load produces vibration, and can damage the unit. A 2 gram load imbalance, at a speed of 4600 RPM, imparts force equivalent to 9.1 kg (20 pounds) at rest. Always ensure that the rotor is loaded symmetrically, with a full complement of accessories, and a full (or paired) set of tubes. - Page 17 Tubes loaded into swinging bucket rotors must be symmetric, around the axis of rotation. Verify this by rotating the entire rotor 180°, by hand. The loads should be in the same apparent positions (not mirror images). In addition, the loads within each bucket must, also, be symmetric around the bucket’s pivot axis.
- Page 18 Vibration All centrifuges have critical speeds, at which vibration occurs. As the speed increases, beyond the critical speed, vibration will cease. This inherent condition, also, occurs during deceleration. An imbalanced load intensifies these critical vibrations. Do not continuously operate this centrifuge at observed critical speeds.

3. Lift the rotor off the shaft. Starting and Stopping a Run Read Section 2.5, for a general description of the front panel. The settings displayed on the front panel always govern the operation of the unit. The display above the Program key shows the unit’s operating mode. -
Page 20: Stored Programs
The program will remain in memory until further changes are made. Because the Marathon 3000(R) has a fully automatic rotor recognition system, the very first rotor that is spun using a particular program will be identified and have its identity automatically stored in the program. - Page 21 together with its default radius (if not explicitly entered to the program). To make changes temporary, press START without pressing the SAVE key. The program display will flash, to indicate that the instrument is not currently operating from program mode. The original program will remain unchanged as long as the SAVE key is not pressed.

Page 22: Rotor Recognition System
Rotor Recognition System The Marathon 3000(R) is equipped with a fully automatic rotor recognition system that internally detects and identifies the rotor installed. Since the Marathon 3000(R) was designed to spin a variety of rotors, its software database contains the maximum settable values for speed, RCF, and radius for each. -
Page 23: 3000R Refrigeration
Refrigeration (3000R only) Refrigerated units refrigerate the rotor chamber whenever the cover is closed and the unit is switched on. Refrigeration is applied, as necessary, to cool the rotor chamber to the currently displayed temperature setting. If you use the key pad, and momentarily display a cold temperature (stepping through stored programs, for example), refrigeration will not be activated. -

- Page 26 Error Codes An error code typically means that the internal microprocessor has detected impermissible readings, or a failure, elsewhere, in the unit. Error messages appear in the speed display. When an error code is displayed, unplug and reconnect the unit to power. If the error code reappears, factory-authorized maintenance may be required.

Page 32: Derating Tables
Derating Tables Dense Samples The Speed and Force Tables list the maximum speed for each rotor/adapter combination for the Marathon Series. These speeds are specified for samples whose specific gravity is not greater than 1.2, for swinging bucket rotors. For denser samples, the maximum specified speed is reduced (derated) by a factor from the table below: Derating Factor for: Specific Gravity... - Page 33 Specific gravities greater than 3.0. This table is based on the formula: You can use the same formula to compute derating factors for specific gravities greater than 3.0. • S is the maximum specific gravity allowed before derating (1.2). • S is the actual specific gravity of the sample.
