1. Operating Instruction
1.1 About this manual
This service manual should be used by specialized engineers authorized by Gyrozen
Co., Ltd.
Any repairing work operated by non-authorized personnel cannot be protected and
guaranteed.
This service manual aims to find possible errors quickly and fix them properly.
Refer to the user’s manual for detailed operation of Centrifuge.

Make sure to
1.2.2 Safety Precautions
• Supply proper voltage power according to device’s power requirement.
• Let all repairing works done by authorized or qualified personnel.
• Use rotors or accessories which are approved by Gyrozen.
• Not try to open the lid and or move the device while the rotor is running.
• Operate the centrifuge with a rotor properly attached and secured to the shaft.
• Not use flammable, hazardous, explosive, or corrosive materials.
NOTE: When it is required to use toxic, radioactive materials or pathogenic micro-
organisms, which belong to the Risk Group II of WHO: “Laboratory Bio-safety Manual,”
should follow the regulation guidelines from WHO.
http://www.who.int/csr/resources/publications/biosafety/Labbiosafety.pdf)
• Keep away hazardous materials farther than 30 cm (12 in) from the device during
centrifugation, as recommended in IEC standards 61010-2-020.
• Keep the rpm or rcf under its maximum speed in the case that the density of sample
materials is greater than 1.2 g/ml to avoid rotor failure.
• Load samples symmetrically in the rotor diagonally to make balance between the tubes.
• Balance the load on the rotor totally to prevent the damage to the device even by using
several water-filled tubes.
• Place device on a flat, level, rigid and stable surface.
• Disconnect power supply prior to maintenance and service work to avoid electrical shock.
• Use proper disinfection procedures when centrifuging bio hazardous compounds.
In Blackout
When a blackout takes place while the device is running, the door does not open. And the
rotor speed begins to decrease at natural level. Even if the power turns on before the rotor
stops completely, the rotor does not return to the original speed, but decreases more rapidly
with buzzer sound.
Door opening
The door is closed/opened automatically by a door lock unit operated by a solenoid, and it
will not be opened while the rotor is running at all. Even if the door is opened accidentally,
a door limit switch senses it instantly to make the rotor speed decrease.
Device vibration
If the rotor loses balance while running by any reason, it invokes vibration on the device
itself. In this case the Imbalance sensor senses it and makes the rotor begin to decrease with
preset level issuing Imbalance Error warning. This safety function protects the device from
damage during operation.

2. Installation
2.1 Unpacking
1) Check if the box contains such parts as;
① Power cable, 1ea
② Emergency door open tool, 1ea
③ User’s manual, 1ea
④ Rotor (Optional)
⑤ Rotor coupling device
2) Open the box and lift out the device carefully together with the safety padding.
3) Remove the safety padding and vinyl wrap.
4) Remove the motor fixing bolts
There are 2 screws placed at the bottom of the device. They protect the imbalance
sensor from any damage caused by some accidental moving of the motor during
delivery.
And they should be removed before the installation of the device as follows;
① Check if a long bolt(A came out from bottom of the device. As it is longer than
the leg pieces, the device cannot stand horizontally.
② Check also another screw around the long one.
Bottom side
B A
③ Unscrew and remove the 2 screws with a provided wrench.
5) Place the device on the flat surface.

2.2 Location
1) Install the device at the solid and flat floor or table. If you place the centrifuge at
the slope, the axis of rotation is possibly changed because of the rotor weight.
2) Install the device keeping a distance of 30cm at least from the wall. The distance is
needed for the air circulation around the device.
3) Install the device at the place with appropriate temperature and humidity. These
conditions have to be maintained constantly as soon as possible.
4) Install the device at the place without any kinds of corrosive gases.
2.3 Supply the power
1) 416 model uses 110V or 220V. Check proper voltage of the device and connect to
adequate power outlet.
2) If the power input is more than +/- 10% of the recommended voltage or
fluctuating frequently, it may affect some functions of the device. In that case it is
recommended to use AVR (Automatic Voltage Regulator).
3) If you want to use the device under the other voltage range, please contact us for
safe usage.
2.4 Power On and opening the door
1) Turn on the device by the switch on the right side of the machine.
2) Press the ‘Door’ button to open the door.
If it does not work (door not open), use the emergency door open tool (as the
figure)

2) SMPS; distributes inlet power to each part as appropriate form.
3) Inverter; transforms the single phase power to the 3 phase for running the AC
induction motor.
4) IPM FSBS5CH60; controls the AC induction motor.
5) Solenoid; open and close the door lid automatically.
