8. Electronic System
8.1 Introduction
This chapter describes the replacement and adjustment procedures for the
various electronic parts of the instrument.
This chapter also contains the connection diagrams illustrating how the various
parts of the instrument are interconnected.
The instrument contains the following electronic parts:
1. Main Board
This is the major board in the instrument and contains the microprocessor and
the Analog / Digital converter. The A/D Converter is used to measure the light
that is transmitted through the samples. The light is converted into a digital
value that is be used to calculate the optical density of the sample.
2. Power Board (standard)
This board is used to control the transport motor, filter carriage motor, the 5 Volt
voltage regulation, the lamp control and for the temperature control of the
instrument (fan).
3. Power Board (tuneable wavelength/ 6 Filter)
This board has the same function as the standard board, but there is one more
motor driver for controlling the filter carriage motor (DC Servo Motor by TW
Option). There is also a voltage regulation for the TW board.
4. TW Board
This board is for controlling the tuneable wavelength blocking filter wheel.
5. Thermo Board
This board controls the Nozzle-plate, the fans of TC unit, sensors of the TC unit,
the upper heating plate in the transport box and to regulate the Peltier module
of the Temperature control unit.
6. 12-Volt board
The board convert the 24 Volt input voltage to 24/12 Volt output voltage. The 12
Volt voltage is to control the Peltier module.
7. Power Supply
This unit is used to supply the various voltages that are required by the
instrument.
8. Barcode Board
This board controls the barcode reader.
9. Optical Switches
This section gives the layout and circuit diagrams for the optical switches that
are used in the instrument.
10. WinCE Board
The WinCE Board controls the Touchscreen and processes all the
measurement data.
