FTA125 and FTA188 Kloehn Pump Quick Start
Last updated October 19, 2005
Unpacking
The pump is shipped with the glass syringe installed. It should not be operated if the syringe
appears damaged. A complete description of the pump, including how to change the syringe, is
contained in Versa3.pdf included with your documentation and available on the FTA website in
the Papers section.
Software Installation
The Koehn pump requires a separate serial port. If your computer lacks enough ports, they can
be easily added with PCI cards or inexpensive USB to RS232 converters.
Initial Startup
You will get a warning message when you click OK on the LogOn screen if the computer can
not establish communication with the pump.
Pump Operating Parameters
Certain operating parameters of the pumps and motion axes can be changed by the user. This
provides flexibility in running the instrument, but also is an opportunity for mischief. The
numbers must be reasonable. Numbers which appear in blue are for information only – they may
not be directly changed by the user.
“Total syringe capacity”: This must match the capacity of the syringe to be driven by a
motorized pump. You can change syringe sizes to scale the pump for very fast or slow
operation. The value is in microliters.
“Automatic rate”: This is the rate in microliters per second used in constant-rate dispenses
which are run as part of capturing a Movie. The rate for manual “jogging” is separate, as is the
rate used when the Pump Program is used. Rates which are too fast, typically above 50
