4.5. Photometric control board- CIIM00050
Board located in the reading rotor. It contains a micro controller (U5) which controls the following elements:
• Reaction rotor cover detection (U7)
• Wash station motor (U14)
• Wash station start-up detection (U10)
• Wash station collision detection (U10)
• Photometric board connection
• Reaction rotor motor (U12)
• Reaction rotor start-up detection (U10)
• Reaction rotor encoder detection (13)
• Peltier control in thermostatting the reaction rotor (U18)
• Fan control for cooling the peltiers (U17). ere are 3 fans with 3 wires.
• Reaction rotor thermostatting temperature sensor control (U15 and U16)
