4.6.2 Nephelometric reading

For each cupule of the strip the mini API® performs two types of measurements: Turbidimetry: measurement of the intensity of transmitted light (T) which is inversely proportional to the amount of bacterial growth.

•

• Nephelometry: measurement of the intensity of scattered light (S) at 30°, directly proportional to the amount of bacterial growth.

The reader transmits these two values which enable the estimation of the density of bacterial growth in the medium (turbi-nephelometry) according to the following ratio: Turbi-nephelometry = S / T x 256.

4.12.1 Power supply circuit operation

Figure 4–10 shows the power supply circuitry in the form of a block diagram.

When AC power enters mini API® from an external power source, the filter circuit removes the noise.

4.12.2 Reader power supply

It provides the board COM GEST2 with stabilised +5VDC and +/- 15VDC from the 220V mains. It provides the board power with stabilised +5VDC and +/- 12VDC. The AC voltage then undergoes full wave rectification and is smoothed to produce direct current. A voltage detector circuit is connected to the switching circuit. This feedback control arrangement ensures a stable voltage supply. An automatic electronic current-limiting circuit with automatic recovery limits short-circuit output current to a safe preset value, protecting load and power supply when direct shorts occur. It provides the board power with +24VDC to supply motors and +11,5VDC to supply the lamp.

4.12.3 Computer power supply

It provides the board CPU, hard disk and floppy drive with stabilised +5VDC and +12VDC. It provides the printer with +12VDC. An automatic electronic current-limiting circuit with automatic recovery limits short-circuit output current to a safe preset value, protecting load and power supply when direct shorts occur.

The board power has two main functions:

4.13.1 Filter motor drive circuit

The filter motor, which is a bipolar stepper motor, is used to change the filter during a colorimetric reading. It advances 3.6° per step. COM GEST2 U13 circuit ports (PB2, PB4, PB7) are used to control the filter motor. The filter motor drive circuit (GS D200S) is a complete controller and driver that incorporates all the power functions to directly interface a microprocessor and a two-phase permanent magnet motor. Very little information is sent by the microprocessor to the module.

Step clock •

•

•

Direction (clockwise or counterclockwise CC/CCW).

Reset and enable. Based on this information, the module generates the proper four-phase sequence to directly drive a two-phase bipolar motor. The GS D200S incorporates a thermal protection that switches off the power stages when the junction temperature of active components reaches 150°C.

Figure 4–11: Filter motor drive circuit


4.13.2 Tray motor drive circuit

The tray motor (continuous motor) is used to move the tray in two directions. The P2 potentiometer allows you to adjust the output voltage to drive the motor and thus adjust the speed of the tray. COM GEST2 U13 circuit ports (PB3, PB5, PB1) are used to control the tray motor.

4.14.2 Board power

Pin 13 and pin 18 of the IC11: L293E allow you to control the supply voltage of the tray motor (continuous motor) which is adjusted using P2 on the board power. This verification is possible on pin 1 and 3 of the B1 connector on the board 450 0283A. PT3 is not used during the voltage adjustment. The FU1 fuse protects the +24V on the GS D200S chip against overloading. − T 1A Slow blow fuse.
