Mechanical Components
The AutomaticQC cartridge contains the following mechanical
components:
• cartridge lever
• bag pierce pins
• cartridge connector
The cartridge lever is a spring-loaded panel that, when closed (flush with
the AutomaticQC cartridge base plate), causes pins on its underside to
actuate the pierce probes. The pierce probes engage fittings on the
reagent bags to provide a seal and to puncture the bags to create fluid
paths for the QC material to flow from the AutomaticQC cartridge to the
measurement cartridge. A total of three pierce probes service the five
bags. The AutomaticQC cartridge is shipped with the lever in its open
position.
The cartridge connector is mounted on the front of the AutomaticQC
cartridge. During installation of the cartridge, the connector is moved
horizontally and connects with the measurement cartridge. It provides the
sample path from the AutomaticQC cartridge to the measurement
cartridge. The cartridge connector slide must be fully engaged for the
AutomaticQC cartridge to function.
Electronic Components
The AutomaticQC cartridge contains the following electronic components:
• IDEE assembly
• microswitch
The IDEE assembly consists of a PC board and cable. An EEPROM chip
on the PC board signals the system when the AutomaticQC cartridge is
installed. The EEPROM chip also contains target ranges for each level of
QC material in the cartridge. These ranges are automatically downloaded
to the system when the AutomaticQC cartridge is installed. The cable
connects the IDEE PC board to the cartridge connector microswitch.
The microswitch is located where the cable attaches to the bottom of the
valve enclosure. It determines if the cartridge connector is open or closed.
