1.1 INTRODUCTION
This service manual contains the information needed to perform routine maintenance and service
on the Ohaus centrifuge model FC5714.
Before servicing the equipment, you should be familiar with the Instruction Manual which is packed
with every equipment.
1.2 DEFINITION OF SIGNAL WARNING AND SYMBOLS
Safety notes are marked with signal words and warning symbols. These show safety issues and
warnings. Ignoring the safety notes may lead to personal injury, damage to the instrument,
malfunctions and false results. The degree of danger is a part of a safety note and distinguishes
the possible results of non-observance from each other.

1.3 SAFETY PRECAUTIONS
1.3.1 User
OHAUS centrifuges are intended exclusively for indoor use and for use by qualified personnel. This
device may only be operated by trained specialist staff. They must have carefully read the
operating manual and be familiar with the function of the device.
1.3.2 Rotor and Accessories
Only OHAUS original rotors and accessories shall be used. Any other use or intended use is
considered improper. OHAUS is not liable for damage resulting from improper use.
1.3.3 Measures for your protection
1-2
CAUTION:
Read all safety warnings before installing, making connections, or servicing this equipment.
Failure to comply with these warnings could result in personal injury and/or property
damage. Retain instructions for future reference.
WARNING: Never work in an environment subject to explosion hazards!
The housing of the instrument is not gas tight. (Explosion hazard due to
spark formation, corrosion caused by the ingress of gases)
WARNING: When using chemicals and solvents, comply with
the instructions of the producer and the general lab safety rules.
WARNING:
The centrifuge is not sealed. Use suitable protection
measures when using the centrifuge for infectious and pathogenic
samples. Follow appropriate safety precautions when handling these
samples.

GETTING STARTED 7
1.3.4 Exclude the following environmental influences
•Powerful vibrations
•Direct sunlight
•Atmospheric humidity greater than 80%
•Corrosive gases present
•Temperatures below 2 °C and above 35 °C
•Powerful electric or magnetic fields
1.3.5 Measures for operational safety
•Do not unscrew the two halves of the housing
•Dry off any liquid spills immediately! The instrument is not watertight
•Only use a power cord with a rating that exceeds the specifications on the equipment label.
•Only connect the power cord to a properly grounded power receptable.
•Do not position the equipment such that it is difficult to disconnect the power cord from the
power receptacle.
•Make sure that the power cord does not pose a potential obstacle or tripping hazard.
•The equipment is for indoor use only. Use the equipment only in dry locations.
•Use only approved accessories.
•Operate the equipment only under ambient conditions specified in these instructions.
•Disconnect the equipment from the power supply when cleaning.
•Do not operate the equipment in hazardous or unstable environments.
•Service should only be performed by authorized personnel
1.3.6 Danger and precautions
To protect people and the environment the following precautions should be observed:
•During centrifugation, the presences of people are prohibited within 30 cm around the
centrifuge according to the regulations of EN 61010-2-020.
•FC5714 is not explosion-proof and must therefore not be operated in explosion-endangered
areas or locations. Centrifugation of flammable, explosive, radioactive, or such substances,
which chemically react with high energy, is strictly prohibited. The final decision on the risks
associated with the use of such substances is the responsibility of the user of the centrifuge.
•Never spin toxic or pathogenic material without adequate safety precautions, i.e.
centrifugation of buckets / tubes with missing or defective hermetic sealing is strictly
prohibited. The user is obliged to perform appropriate disinfection procedures in case
dangerous substances have contaminated the centrifuge and or its accessories. When
centrifuging infectious substances, always pay attention to the general laboratory
precautions. If necessary, contact your safety officer!
•It is prohibited to run the centrifuge with rotors other than listed for this unit.
•Under no circumstances open the lid of the centrifuge while the rotor is still running or
rotating with a speed of > 2m/s.
WARNING:
Electrical shock hazards exist within the housing. The housing should only be
opened by authorized and qualified personnel. Remove all power connections
to the unit before opening.

1.8 SERVICE INSTRUCTIONS
1.8.1 General technical description
Model FC5714 is a microprocessor controlled laboratory centrifuge.
The actuation is a three phase asynchronous motor which is controlled by a
frequency converter.
Model FC5714 has an independent error detection program, displaying possible
errors and therefore supporting the trouble shooting process.
This unit is equipped with several safety features:
• Imbalance detection
• Motor over temperature protection
• Lid lock does not open until the standstill of the centrifuge
• Rotor over speed protection
Please follow below mentioned safety instructions for any kind of service
actions:
• The capacitor of the frequency converter can be under voltage even when the unit is
switched off.
• Do not leave units unsupervised, when parts of the housing have been removed and
the unit is still connected to the main power supply.
• Do not bypass the lid’s safety contacts and never work with the unit’s lid open.
• The VDE regulations are valid for all electrical work that has to be done.
1.8.2 Electrical and electronical components
1.8.2.1 Power board
The power board is serving the low voltage supply of the centrifuge control system.
The power board is electrically isolated and has a dielectric strength of DC 2.2 kV.
1.8.2.2 Control board (PCB)
The control board consists of one plate. The board can only be exchanged completely.
If there is a defect you have to exchange the complete board, not only the printed
circuit board.
All signal lines lead to the control board.
The PCB controls the entire centrifuge.

12 GETTING STARTED
1.8.2.3 Control panel
The control panel consists of one LCD-display, one incremental shaft encoder, the upper
front housing and the foil keyboard. These parts can be exchanged separate. The
incremental shaft encoder regulates all parameters which are adjustable by pressing a key
and which are indicated in the LCD-display. In the speed display of the control panel the
error message is indicated if there should occur any trouble
1.8.2.4 Frequency converter
The frequency converter generates the drive signals for the asynchronous motor.
The converter leads the current generated by the motor during deceleration to a
heating resistor to reduce the current.
The frequency converter is connected with the power board by a serial interface.
There is a green LED on the converter which flashes when the frequency converter is
working correctly.
A defect of the converter will be indicated in the speed display as an error no.

LCD-Display
Potentiometer
Keyboard Foil

GETTING STARTED 13
1.8.2.5 Rotor recognition and over speed protection
The centrifuge will recognize the inputted rotor through the rotor identification
transponder and the aerial belonging to it right after the insert automatically. As soon
as the lid gets closed the rotor number will be indicated in the speed display.
If the pre-selected rpm is higher as the permitted rpm of the rotor, the speed
indication in the display will be regulated to the max.speed permitted for this rotor.
The regulation will accelerate the rotor only to the permitted rpm of the rotor.
1.8.2.6 Speed signal
The actual speed is extracted by a hall-effect-sensor placed on the lower side of the
motor.
There is a „preset/actual“comparison in the control board. Thereupon a new “preset-
signal” is given by the control board to the converter.
Transponder

14 GETTING STARTED
1.8.2.7 Lid contact
The micro switch in the mechanism of the lid lock controls the correct closing of the
centrifuge lid.
The switch may never be bypassed.
The lid lock is unlatched by an electro motor, receiving its signal from the control
board.
1.8.2.8 Imbalance detection
The imbalance detection is effected by a movement sensor, which is mounted in the
motor and is controlling the oscillating motion of the motor. The unit stops when the
oscillating motions are too strong. Therefore you have to follow the adjustment
instructions stated by the manufacturer.
