Figure 6-7 Level Detection Board Function
6.6.8 Reaction Disk Temperature Sampling Board
This board collects signals from the reaction disk temperature sensors and then converts
them into digital signals. This board provides an SPI interface, and is connected to the
main board.
6.6.9 Three Probes Connection Board
This board transfers the control signal of the reagent preheating, mixer motor pulse and
level detection board.
6.6.10 ISE Power Board
The board supplies the transformation of the voltage from 12V to 24V which provides
power to ISE module.
ISE module should be on power all the time, and the input 12V is provided by 5V/12V
Board.
6.6.11 Heater Voltage Selecting Board
The board supplies two connection type for the 220V AC power and the 110V AC power
separately. If the AC power is 220V, please use the socket for 220V; if the power is 110V
AC power, please use the socket for 110V. The heater will provide the same power
consumption so as to ensure the effect of the heating in the different AC power
environment.
