Connecting the Model EP-1 Econo and Econo
Gradient Pumps
The BioFrac fraction collector can start an Econo gradient pump or
Model EP-1 Econo pump remotely. To make the necessary connections you will
need a BioFrac accessory cable (catalog # 731-8290) and system cable 7 (catalog #
731-8267).
1. Connect the BioFrac accessory cable green/black and blue/white wires to the
system cable 7 blue wire.
2. Connect the BioFrac accessory cable’s orange/black wire to the system cable 7
yellow wire if you are connecting to an Econo gradient pump, or red wire if you
are connecting to a Model EP-1 Econo pump.
3. Trim off all unused wires.
4. Connect the end of the BioFrac accessory cable with the 15-pin D connector to
the I/O port on the BioFrac fraction collector.
5. Connect the system cable 7 mini-DIN connector to the I/O port on the Econo
gradient pump or Model EP-1 Econo pump.
6. With the fraction collector in Local mode, press Run to start the fraction
collector and pump.
7. If you are collecting by volume, be sure to enter the pump flow rate into the
BioFrac device’s flow rate entry field.
Note: Pressing Stop on the BioFrac fraction collector will not stop the Econo
gradient pump run. The EGP program must be stopped from the Econo
gradient pump faceplate.
Connecting to Components Not Manufactured by
Bio-Rad
The BioFrac fraction collector is designed to work with a variety of components
from other manufacturers. The BioFrac fraction collector can control remote devices
such as pumps, chart recorders, and UV detectors, and it can accept start/stop
signals from other equipment, such as pumps and UV detectors. The following is a
description of the remote fraction collection control options. To connect the fraction
