Electronic Description
bibag Interface Board
The bibag interface board ‘piggybacks’ onto the actuator - test board and communicates
with it. The bibag hydraulic assembly and the bibag distribution box 2 connect
electrically to the bibag interface board with ribbon cables.
The bibag interface board contains all of the electronics required to activate the 5
additional valves, read conductivity from the bibag and bicarbonate conductivity cells,
read temperature from the bibag and bicarbonate temperature thermistor, read the status
of the bibag air sensor, and read the status of the bibag door’s internal switches. A
microcontroller on the board controls all of these processes and communicates serially
with the actuator - test board. The presence of the communications between the bibag
interface board and the actuator - test board indicates to the system the presence of the
bibag hydraulic components.
The bibag pressure transducer is automatically calibrated when the door is open, and the
value is saved into memory on the bibag interface board.
bibag Hydraulic Assembly – Distribution Board
The bibag hydraulic assembly - distribution board is a passive board that connects to the
bibag interface board through a 26 pin cable. All of the individual bibag components on
the bibag hydraulic assembly connect electrically to this distribution board.
bibag Distribution Box 2 – Distribution Board
The bibag distribution box 2 - distribution board is a passive board that connects to the
bibag interface board through a 20 pin cable. All of the individual bibag components on
the distribution box 2 connect electrically to this distribution board.
