Mode
Once your valve package has been properly installed and you have
ensured that fluid connections are leak-free, the system is ready for
operation.
NOTE
Teledyne ISCO convention is to name the pumps “pump A” and
“pump B,” reading from left to right.
Before running in Continuous Flow Mode, become familiar with Inde-
pendent Mode, which allows the controller to operate two pumps inde-
pendently and simultaneously. You must operate the two pumps
manually for initial setup (i.e. refill and purging of air). If the
Teledyne ISCO air valve package is used, the air valves are switched
through ACCESS CTRL. When air valves are used, lights on the air
valve actuator indicate which valves are open.
5.5.1 Defining Operation
• Select Pump - This menu allows you to select any pump to
display its run screen (program and operation data) and to make
program changes.
• Valve specification - To prevent pressure fluctuation at
switchover, you must specify the type of valve package you are
using.
NOTE
If you are using Ball Valves (500xv only) and are not using a check
valve in the supply reservoir tube, it may be necessary to turn the
No Check Valve option on. Refer to Section 5.5.4 "No Check Valve"
for additional information.
