To connect the fraction collector to a BioLogic DuoFlow system
1. Connect the bus cable to the connector marked INSTRUMENT BUS on the
base of the fraction collector.
2. Connect the other end of the bus cable to either the INSTRUMENT BUS
connector on the back of the BioLogic DuoFlow workstation or to other
Bio-Rad components that are daisy chained to the BioLogic DuoFlow
workstation by the instrument bus.
3. Place the BioFrac fraction collector in Local mode with the Main screen
displayed (see
Main Screen on page 36 ). Start the BioLogic DuoFlow software
and press System in the manual screen fraction collector dialog box.
Note: The BioFrac fraction collector must be in Local mode and on the
Main screen before the BioLogic DuoFlow system can control it.
Connecting to a BioLogic LP System or to a
Model
EP-1 Econo Pump
To connect the fraction collector to the BioLogic LP system or Model EP-1 Econo
pump requires system cables 3 and 15. System cable 15 relays the fraction advance
signal to the BioFrac device, and system cable 3 allows the BioLogic LP system or
Model EP-1 Econo pump to control the BioFrac fraction collector’s diverter valve.
