1.0 Description of the Centrifuge
The centrifuge is composed of:
•
an electrical block, called Control Center.
•
a lock
•
a motor
•
a ventilation or refrigeration system (depending on the model)
•
a one-piece frame
•
a lid
It is equipped with one or several rotors:
•
Free or swing-out
•
Angular
The free rotors are fitted with:
•
Buckets
•
Tube adapters or inserts
•
Watertight lids
Some angular rotors are equipped with tight fitting lids.
1.1 Electronic Control Center / Block
The electrical block, or Control Center, includes a touch screen, a control button, the main switch, a lid opening button, as
well as the microcontroller electronic board, and the electrical power supply electronic board.
There is no provision for changing the elements composing the Control Center. It is a complete separate part. In case of
defective element, a standard exchange of the complete Control Center must be considered, which facilitates the
restoration of the centrifuge.
Touch Screen
The display is based on a TFT type display its size is 4.3”. It offers 480X272 pixels, and 16 Million colors.
It is also equipped with LED lighting for bright background.
The screen is also touch, and resistive type. It provides access to many features when using the interface.
The display and display card unit is located in the upper part of the Control Center.
Start/Stop Button
The control button placed under the screen allows for controlling the startup and interruption of a centrifugation cycle.
Main Switch
The main switch is located under the Control Center. It allows for completely shutting off power to the centrifuge.
Cover Opening Button
The lid opening is controlled by the button on the right side of the Control Center.
Electronic Tachometer Board
The electronic microcontroller board is located under the display card. The data for controlling the various parts are
stored in this board, in the form of software, also marked “Display fw”
The connection for the update of this software is below the Control Center, via the connection kit
part no. AFI-71122001.
The procedure is described in the Technical Bulletin CTB0311 Software Programming.
This board communicates with:
•
The tachometer board
•
The various lid position sensors for detecting the lid position,
•
The touch display card
•
The programming connector
•
The temperature probe
•
The Start / Stop control button on the membrane
•
The lid opening button on the right side of the Control Center.
