Operation 4
Programming a Method
If you link files together which have different
values for the setup parameters, the pump will not
start. After pressing Run the display will give you
the message Note ! Setup has changed since file
creation. Pressing Ok gives you the choice of which
setup parameters to keep by asking the question
Keep original setup ? Yes - No. If you choose Yes,
the values which are stored in the first file in the
sequence of files will be loaded into all of the files
which are linked together. If you choose No, the
values which are currently stored in the pumps
setup parameter memory will be loaded into all of
the files which are linked together.
# The default value is None.
• Key in the number of the file you want to link to
and press Enter, or press the None soft key.
This brings you to the Choose an event type screen.
Menu: Choose an Event Type
There are five different types of timed events. You
choose one of the different events by pressing the
soft key below it. The five timed event types are:
• Mixture
Program the composition, %A, %B and %C.
• Flowrate
Program the flow rate, mL/minute.
• Wait
Wait for an input.
• Out
Activate an output.
• Inject
Activate the injection pump.
At the end of each operation, the solvent consump-
tion will be displayed.
Mixt
Set the composition of the solvents, e.g. 70 % solvent
A, 20 % solvent B and 10 % solvent C. There is a
maximum of three pieces of data for this menu:
- Time at which composition occurs
- % of solvent B
- % of solvent C.
One complete method program
is stored in a file. The values for
the six parameters; Refill Time,
Compressibility, Pump Head
Size, Inlet Pressure, High
Pressure Limit and Low Pressure
Limit for that method program
are also stored in the same file.
If you link two or more files
together, you must ensure that
they all have the same values
for these parameters.
In the case of linking an error
file which has different setup
parameters to the method file,
the parameters for the method
file automatically replace the
values which were written in
the error file.
