Bio-Rad Model EP-1 Econo Pump - Manual (Page 20)

7.3 Use of the Econo Pump with the BioLogic
System
The Econo Pump can be controlled by the BioLogic System and used
as a sample loading pump.
Note: The Econo Pump must have v2.12 software in order to accept
on/off commands from the BioLogic System. See Section 10.1 for
instructions on how to check the software version. If an upgrade is
required, contact your local Bio-Rad representative.
To connect the Econo Pump to the BioLogic, use System Cable 7
(catalog number 731-8267). Connect the mini-DIN end of the cable to the
AUX port of the Econo Pump, and make a bare wire connection to the AUX
port of the BioLogic Workstation (RED to port 6, BLUE to port 9).
To connect the wires to the AUX port of the BioLogic System, turn the
small flathead screwdriver counterclockwise to back out the screw. Insert
the bare wire into the port and turn the screwdriver clockwise to secure the
connection. Be sure to calibrate the pump and set a flow rate prior to using
the Econo Pump with the BioLogic System, since the BioLogic sends only
“on/off” commands to the Econo Pump. To program the Econo Pump as a
sample loading pump with the BioLogic System, refer to the BioLogic
System user manual.

Cleaning and Maintenance
The Model EP-1 Econo Pump requires very little maintenance to assure
reliable operation. The procedures outlined below will insure maximum
pump life:
• Check tubing regularly for signs of cracking and wear. If any exist,
replace the tubing.
• For optimal tubing life, use a slow to medium pump speed. To increase
throughput, increase tubing size to obtain the desired output.
• When not in use, tubing should be removed from the pump to prevent
deformation of the tubing. Remove the platen and relax the tubing by
unhooking one end of the tubing from the tubing bracket.
• To prevent the formation of precipitates around the pump head and on
the membrane key panel, promptly remove any spills. Clean with
deionized water.
