Cartridge Interface Module - Bayer HealthCare RapidPoint 400 Series Service Manual

Cartridge Interface Module

The cartridge interface module attaches the measurement cartridge to the
system. It consists of the following components:
• interface frame
• location pins
• bag pierce pins
• cable clamps
• cartridge handle
• valve actuator
• optical detector board with bidirectional stepper motor and position
detectors
• pump and motor assembly (refer to Pumps on page 52 for more
detailed information)
• thermal cover
• camshaft
• connector block
The interface frame is secured to the front of the system and holds all
devices and parts necessary to interface the system with the measurement
cartridge.
The location pins position the measurement cartridge on the cartridge
interface frame. Three bag pierce pins are below the location pins. The bag
pierce pins force the pierce probes to puncture the reagent bags creating
a fluid path. The pierce probes engage with the fittings on the reagent bags
to make a seal.
Four cable clamps secure the cables that extend from the connector block,
the stepper motor, and the optical detector board to the main board.
The cartridge handle lifts to unlock and release the measurement cartridge
from the interface module, or pulls down to lock the measurement cartridge
in place on the cartridge interface module.
