Introduction
1
Gilson’s 305 Master pump conform to the standard specified in the ‘Declaration of
Conformity’ certificate (reference LT801354) supplied with the instrument.
The 305 Master pump is designed as a system controller. It can operate as a stand-alone
isocratic pump or as a system controller, to deliver fluids (liquids or liquefied gas when
specially equipped). As a system controller, the 305 Master pump controls a complete
pumping system, elution pumps and injection pump.
The 305 Master pump can operate in three different modes. These modes are:
Flow:
The 305 pump provides a constant flow rate. The pump starts when the Run
key is pressed and stops when the Stop key is pressed. The flow mode is for
isocratic use only.
Dispense: The 305 dispenses a specified volume. The pump starts when the Start key is
pressed and stops when the specified volume has been dispensed. The
dispense mode is for isocratic use only.
Program:
The 305 controls a multi-pump system with up to 2 slave elution pumps and
1 slave injection pump. In this mode, the 305 Master pump can create
gradients of flow rate and composition, open and close outputs to control
other instruments and wait for signals from other instruments.
The operation of each mode is explained in Chapter 4.
The present software version is 3.01.

For safety reasons, the 305 is shipped without the
fuses installed and with the voltage selector in the
220/240 Volt position. You must:
• Insert the correct fuses.
• Set the voltage selector to your local voltage.
Inserting the Fuses
Ensure that the power cord is not connected before
starting to install the fuses. Follow the procedure
below to install the two fuses.
• The voltage selector and fuse holder is located
under neath the power socket. See opposite figure.
Pull the voltage selector out of the power
receptacle. This is done by gently levering the
selector out using a small screwdriver.
• Pull out the drawer as shown in the figure
opposite. Insert the first fuse into the clips.
• Push the drawer back into position.
• Pull out the drawer for the second fuse which is
on the other side of the voltage selector. Insert the
second fuse into the clips.
The instrument requires two fuses to be installed.
The type of fuses required are: 2.0 Amp type “T”
slow blow for 100 -120 V, 1.0 Amp type “T” slow
blow for 220-240 V.
For safety reasons, piston pumps are delivered
without fuses installed. Fuses must be installed by
the user upon delivery.
Selecting the Voltage
The 305 can be set to operate at 100/120 volts or
220/240 volts. The different voltages are selected
depending on the orientation of the fuse holder.
To set the voltage to 100/120 volts:
Insert the fuse holder with the numbers 110/120 on
the bottom, facing the small white arrow.

Mechanical Installation
This section explains how to install the pump head,
the mast clamp and mast. The pump head and mast
clamp for each pump should be installed before
positioning the modules.
Pump Head Installation
The pump head is shipped in a hard case to protect
it during transit. Unpack the pump head from its
case and check that all of the parts are included.
Follow the procedure below to install the pump head.
• Insert the pump head into the front aperture of
the pump. See the opposite figure. The notch at
the bottom of the pump head body must be fitted
onto the matching pin on the pump, just below
the aperture. This notch ensures that the inlet port
is on the bottom and the outlet port is on the top.
• Holding the pump head in place with one hand,
set the clamp diagonally over the head.
• Turn the clamp clockwise into position in the slots
on both sides of the pump head.
• Tighten the thumb screw until the clamp holds
the pump head securely. Make sure that the clamp
ends are secured in their slots on both sides.
See the pump head User’s Guide for more information
on the pump head.
Mast Installation
The mast is used to stabilise a system when several
modules are stacked on top of each other. It can also
used to hold the prime/purge valve and a manual
injection valve. The mast clamp should be installed
before positioning the 305 Master pump in a system.
The mast is added after all of the modules have been
put in place. Follow the procedure below to install the
mast clamp.
• Remove the side screw holding the module cover.
See the opposite figure.
• Screw on the mast clamp.

Installation
Mechanical Installation
Fix one clamp onto each pump in the system. After
all the modules have been positioned, the stainless
steel mast can be secured within the clamps. The
lower end of the mast should be level with the
bottom of the lowest pump.

Positioning the Modules
Installation
Positioning the Modules
Before putting each module in position, make sure
that each module is ready, i.e. that the fuses have
been installed and that any mechanical installation
is finished.
The physical positioning of each of the modules in
your system will depend on your type of system.
Some suggested layouts are given below. These
layouts have been desigend to make the hydraulic
and electrical connections as simple as possible.
Manual Injection System
This is a binary gradient system with two pumps,
one manometric module, one mixer and one
detector. The pumping system consists of one 305
Master pump and one 306 slave pump. The different
modules should be located as shown in the figure
opposite.
The detector is located at the bottom of the stack and
the pumps and other modules are positioned over it.
The 305 Master pump should be the top pump. This
makes the hydraulic connections to the manometric
module as short as possible which gives the best
results. It is also easy to read the display and to use
the keypad.
Auto-Analytical System
This is a binary gradient system with two pumps,
one manometric module, one mixer, one detector
and one auto-sampler.
The pumping system consists of one 305 Master
pump and one 306 slave pump. The 305 Master
pump should be the top pump. This makes the
hydraulic connections to the manometric module as
short as possible which gives the best results. It is
also easy to read the display and to use the keypad.
The figure opposite shows the layout with a Gilson
231-402 auto-sampler. The next figure shows the
layout with a Gilson 232-402 auto-sampler.
3-6
Installation
This is a binary gradient system with two elution
pumps, one injection pump, one manometric module,
one mixer, one detector and one fraction collector.
In this configuration, automatic injection is
performed by the injection pump, located
below the master pump.
The pumping system consists of one 305
Master pump and two 306 slave pumps. The
305 Master pump should be the top pump.
This makes the hydraulic connections to the
manometric module as short as possible
which gives the best results. It is also easy to
read the display and to use the keypad (see
the opposite figure).

Control Connections
Control Connections
After positioning all of the modules in the system, it is
necessary to connect each module to the system
controller. Two types of electrical connection must
be made.
• The manometric module must be connected to the
305 Master pump.
• All of the slave pumps must be connected to
the Master pump using the GSIOC cable provided.
Connecting the Manometric Module
The manometric module has two functions, to
dampen the pulsations of the pump and to supply
the current pressure value to the Master pump. The
Master pump needs this information to accurately
control the flow rate and to ensure that the system
pressure is not above or below the control limits
entered in the program. The opposite figure shows
the connection for the manometric module.
Connecting the 305 to other Gilson
Modules
The 305 Master pump and the other modules in the
system communicate using the Gilson Serial Input/
Output Channel (GSIOC). Each slave module
controlled by the 305 Master has a GSIOC connector
on its rear panel and is connected to the 305 Master
using the GSIOC cable provided. It is possible to
connect the 305 Master pump to two slave modules
using this cable. If there are more than two slave
modules, two GSIOC cables can be connected together.
The opposite figure shows the GSIOC connections for
a system with 3 elution pumps and on injection pump.
To connect the 305 Master pump to the slave pumps:
Connect the socket marked GSIOC TO SLAVE on
the rear panel of the 305 Master pump to the slave
pumps using the GSIOC cables provided.

Control Connections
looking at the rear of the 306 pumps and ensuring
that the correct switch (2, 3 or 4) has been switched
into the bottom position. The switches are labelled
REMOTE, and are numbered 1 to 8 from left to right.
Connecting the 305 to a 307
The 305 Master pump can directly control a 307
pump without the addition of a manometric module
and with pressure display on the 305 screen.
In this case, the value 2 must be entered in the 307
software as a GSIOC identification number for the
307 pump. If this is omitted, the pressure value
dispalyed by the 305 will remain at zero. The
remedy is to first correct the 307 identification, then
to switch off and on the two pumps.
Set-up 1
Hydraulically, the 307 should normally be used for
solvent B, and set-up 1 is recommended (rather
than set-up 2) for the following reasons:
• As it is usually the case in Gilson gradient
systems, solvent B, of higher elution strength
than A (and normally more expensive), does not
enter the pulse dampener. This makes purge
easier.
• Tubing is shorter and fewer elbows are required.

Operation
Priming the Pump Head
Priming the Pump Head
Do not run the pump when the pump head is dry.
This can result in severe pump head damage.
Check that the solvent bottle is filled with HPLC
grade, degassed solvent or buffer. Immerse the inlet
tubing filter into the solvent reservoir. Make sure that
all of the hydraulic connections are properly made.
Before priming, all electrical connections must be
made, and all hydraulic connections in place. All
pumps present in the system, A, B, C and Inj can
be primed in the Program Mode using the 305
Prime command. However, the pumps must be
connected and declared present in the “Setup
Pump Hardware” procedure, page 4-5.
For 5SC, 10SC, 10WSC and 10WTi pump heads,
use the syringe supplied with the pump head to
prime the pump as follows:
• Attach the syringe to the luer fitting of the low
pressure prime valve (refer to the figure below).
• Draw liquid into the syringe with the low pressure
prime valve in the SYRINGE LOAD position.
• Turn the valve to the SYRINGE-INJECT position.
Press the PRIME key on the front panel of the
305, the screen will indicate which pumps are
present, and you simply select which pump you
wish to prime by pressing the Pump key until the
desired pump has been selected. Press Run and
the pump will start running at its maximum speed.
Depress the syringe (if used) until the pump inlet
is clear of bubbles and some liquid has passed
through the pump outlet.

Operation
Setting Up the Pump
With a new pumping system, you must enter data
about each pump connected, i.e. Refill Time, solvent
Compressibility and pump Head Size and Inlet
Pressure. This is done using the Pump branch of the
software. Data concerning the overall pumping
system, for example high pressure limit, low pressure
limit etc. is done using the I/O branch of the software.
The File branch is used for writing files of method
programs. The Mode branch is used to operate the
system in one of three possible modes, Flow,
Dispense, or Program Mode.
The specifications for Pump and I/O must be set for
a new system setup, or when the physical setup of
the pumping system is changed, for example,
changing a pump head size or removing or introducing a pump.
Set Up Pump Hardware (PUMP)
A pumping system consists of a minimum of 1
pump and a maximum of 3 elution pumps and
1 injection pump. Pump A, the first elution pump
(the 305 Master pump), is always present.

or Off. This function only controls the operation of
the buzzer, it does not affect the operation of the
pump when there is an error.
If the alarm is set to be On, the warning buzzer
will sound every time an error is encountered. An
error can be a pressure limit encountered, an
invalid setting, or a pump absent. This setting can
be changed from On to Off by pressing the soft key
under Change.
# The default setting is Off.
• Select the option you want and press the Next
soft key to go to the next menu.
GSIOC Unit ID Number
Each pump in a multipump system has to have an
identification number to distinguish it from other
pumps and equipment connected to the GSIOC
communications channel.
When using a 305 Master pump, you must have
the identification numbers detailed in the table
above for the slave pumps. The Master pump can
have any number between 0 and 63, however the
default value of 1 is recommended for simplicity.
# The default value is 1.
• Key in the identity number you require for this
pump and press Enter.
Do not set the Master pump ID
number to 2, 3 or 4 as these
numbers are reserved for the
Slave Pumps and Injection
Pump.
Output Contacts (Ouptut #xx is Open / Closed)
There are three relay outputs in the 305 Master
pump numbered 1, 2, and 3. These outputs can be
used to control other instruments. They can be
programmed to open and close during a method
run. They can also be opened and closed manually
using soft key commands.
To change the state of an output, key in the number
of the output, for example output # 2. When you
press Enter, the display will show the present state
of output 2, i.e. Output # 2 open/closed. Press the
soft key Change to change the state of the output.
4-11

Setting Up the Pump
Operation
Setting the outputs manually is
useful to check that output # 1
turns on the integrator for
example. However, when
repeating the same operation
many times, it is better to
program the output operations
as part of a method program. In
this way, the outputs will
follow the same sequence each
time the method program is
run. Refer to programming the
outputs in Section 3 of this
Chapter.
By using this procedure, each of the three outputs
can be manually set to be open or closed. The
outputs will remain in this state until a method
program is run and a change in the outputs is
programmed.
# The default state is open.
• Press Next and go to the next menu.
Pause Prog With/Without Flow
This option runs in Program mode only. It enables
the system to be controlled from an external sensor.
For example, a temperature sensor can be used to
pause the system if the temperature is outside a
desired range. The program and flow can be
paused together, or the program can be paused
whilst the flow rate continues. External parameters
such as temperature, pressure, or composition can
be monitored to control the system.
Gradient Profile
This function only operates in the program mode,
and enables a selected gradient profile to be output
to a recorder from the analog output of the 305.
The gradient profile can be selected as being a
solvent composition, %B or %C or the flow rate
(Flow). The solvent composition can be useful for
biochromatographic applications for plotting pH
gradients and salinity (salt concentration) gradients.
The flow rate can be useful for verifying detector
stability.
The analog output gives 1 V full scale. The full scale
represents 100%B, 100%C or 100% of the maximum
possible (not programmed) flow rate of the system.
This output is from connectors 12 and 13 on the I/O
connector at the back of the 305. Pin 13 is the ground
(0 V) connection.
Options are:
Flow,
%B, %C.
# The default setting is Flow.
• Press the Change soft key to select your desired
output and press Enter.

Operation
Setting Up the Pump
Delay Volume
When the selected gradient profile is a solvent
composition (%B for instance), the Delay Volume
can be used to synchronise on the recorder the plot
of the programmed profile with the plot of the
detected profile (baseline drift). In this case the
delay volume is generally defined, for a first approximation, as being the total volume between the
mixer inlet and the detection cell inlet. The value is
adjusted from experimental observation to obtain
the desired synchronisation.
The 305 software divides the Delay Volume by the
total flow rate to calculate the total delay time
applied to the analog output Gradient Profile. The
size of the Delay Volume can be specified between
0.01 mL and 999 mL.
The Delay Volume option will
only appear if %B or %C has
been selected for Gradient
Profile.
# The default value is 0, i.e. no delay volume specified.
• Key in the required delay volume and press Enter.
Zero Manometric Module
The Zero soft key is used to set the manometric
module value to zero when there is zero pressure in
the system. This ensures accurate pressure readings
when the pumps are running. Before pressing the
Zero soft key, make sure that all pumps have stopped
and that the pressure has dropped to zero. Otherwise further pressure indications will be incorrect.
This can be easily done by opening the prime/purge
valve whilst the pumps are not operating. If the
operation is successful the message Pressure reading is zero is displayed. If the operation is not
successful, the message Not done - check pressure
readings is displayed.
You have now completed the Input/Output parameter setup. Press Quit to leave this branch of

After entering the data about the pumping system, the
pump is ready to run. The 305 Master pump can
operate in three different modes. These modes are:
Flow: The 305 pump provides a constant flow rate. The
pump starts when the Run key is pressed and stops
when the Stop key is pressed. The flow mode is for
isocratic use only.
Dispense: The 305 dispenses a specified volume. The
pump starts when the Start key is pressed and stops
when the specified volume has been dispensed. The
dispense mode is for isocratic use only.
Program: The 305 controls a multi-pump system with
up to 2 slave elution pumps and 1 slave injection
pump. In this mode, the 305 Master pump can create
gradients of flow rate and composition, open and close
outputs to control other instruments and wait for
signals from other instruments.
The operation of each mode is explained.

Before creating a method program in the 305
Master pump, it is necessary to understand how
the method programs are stored in memory.
Memory Layout
There are 14 files, numbered 1 to 14. Each file can
store 1 program. Files 1 to 10 are user files, available for method programs. Files 11 to 14 are reserved for safety/error programs.
A file contains timed events. A timed event is a
flow rate, a solvent composition, the operation of
an input or output or the operation of an injection
pump. One file stores a maximum of 25 timed
events which can make up the method program.
The Safety Files, 11 to 14, do not contain pre-stored
programs you can write each Safety File according
to your own requirements, for example, to output a
control signal to an external device. Write each
safety program in the same way as a method
program. This allows you to program the sequence
of events that will happen when an error occurs. If
an error occurs during a run, the method program
stops and the relevant safety program starts. If no
safety program has been written, the default operation in the event of an error is described in each
relevant Safety File description. See pages 4-31 to
4-33 for the exact operation of Safety Files.

Programming a Method
A complete method program is written by programming flow rates, solvent compositions and
operation of the outputs. The method program run
time starts at time 0.00, i.e. when the start key is
pressed, and ends at the time of the last timed
event. For example, if you program the last event at
time 20.00, then the run time is 20 minutes.
You must program every event for your method,
starting at time 0.00. For example, at time 0.00 you
must program the flow rate and composition. If
you do not program anything at 0.00 minutes, the
pump will assume the current flow rate and composition. For a pump which is stopped, the software will assume a flow rate of 0 mL/min and a
composition of 100% A, 0% B, and 0% C. If the
pump is running, it will assume the current flow
rate and composition for time 0.00. It will then
operate on a gradient between these values and the
first flow rate in your program and the first solvent
composition in your program.
Menu: Number of Loops
The number of loops is the number of times that the
program will repeat itself before stopping. The
minimum value is 1 and the maximum value is 999.
# The default value is 1.
• Key in the number of loops and press Enter.
This brings you to the When finished, use menu.

Operation
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.
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.
• Out
Activate an output.
• Inject
Activate the injection pump.
At the end of each operation, the solvent consumption 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.
4-25
4
Programming a Method
Operation
The percentage of solvent A is calculated as:
% solvent A = 100 - % B - %C.
The example opposite is for a binary gradient.
At 0 minutes, there is 95% solvent A and 5%
solvent B. At 5 minutes, there is 80% solvent A
and 20% solvent B.
Example:
There will be a linear gradient
between two solvent composition points. With the example
given, the %B will increase
linearly from 5% to 20% in 5
minutes. If you change the
gradient point during a run, the
new gradient will be between
the next programmed gradient
value and the value which
existed at the instant the
gradient was modified.
If you do not program a
composition at 0.00 min., the
pump assumes the current
composition. For a stopped
pump, this will be 100% A.
There will then be a gradient
between 100% A and the first
programmed solvent composition point. Programming the
example above will give a
composition gradient as shown
in Figure.
0.00 min
5.00 min
5%B
20%B
(%A = 95%)
(%A = 80%)
To program the example:
• press the Mixt soft key.
• key in the time for the first composition point,
0.00, and press Enter.
• key in the value for the %B, 5, and press Enter.
• press the Add soft key to add a second timed
event to the program.
• key in the time for the second composition point,
5.00, and press Enter.
• key in the value for the %B, 20, and press Enter.
Composition parameters can be set down to 0.1%
increments. If you key in a value which is too high
(sum A+B+C>100%) the last entry will not be
accepted by the software and you must key in the
last value again, or correct your composition specification.
Flow
In this menu, you can set the flow rate, for example,
2 mL/min. There are two parameters to specify for
this menu.
- Time at which flow rate occurs.
- Flow rate in mL/min.
Example: 0.00 min
5.00 min
0.00 mL/min
3.0 mL/min
To program this example:
• press the Add soft key.
• press the Flow soft key.
• key in the time for the first flow rate, 0.00, and
press Enter.
4-26
4
Operation
• press the Add soft key to add a second timed
event.
• key in the time for the second flow rate, 5, and
press Enter.
• key in the second flow rate, 3, and press Enter.
If you try to enter a flow rate value which is too
high for the pump head, the entry is refused by the
software. The maximum value accepted in a gradient system is the value of the smallest pump head
size in the system.
There will be a linear gradient
between any two programmed
flow rates. With the above
example, the flow rate will
linearly increase from 0.00 mL/
min to 3.0 mL/min in 5.00
minutes.
Programming a Method
• key in the value for the flow rate, 0, and press
Enter.
If you do not program a flow rate at 0.00 min., the
software will assume the current flow rate for the
time 0.00 min., i.e. for a stopped pump, a flow rate
of 0 mL/min. There will then be a gradient between 0 mL/min. and the first programmed flow
rate. With this example the flow rate will be as
shown in the opposite figure.
To stop the flow of solvent at the end of a run,
you must program a flow rate of 0 mL/min. Otherwise, the pump will continue to run with the last
programmed flowrate, even after the last timed
event. If there is more than one pump in the system,
you must program a composition point containing
all of the pumps followed by a flow rate of
0 mL/min.
If the system is set up to do more than one
sample, the initial composition for the
method can be maintained between method
runs by programming this composition at
the end of the program, for example 5% B.
At the end of all the samples, link to another file to completely stop the flow of
liquid. See the opposite figure.
Wait
In this menu you can make the program wait until
Input # 1 is activated. This is used to stop the
program until another piece of equipment is ready,
for example an auto-sampler or a fraction collector.
There are two pieces of data for this menu.
4-27

Programming a Method
Operation
- Time at which the pump will wait for an input
- Waiting for an open contact or a closed contact
Example 4:

Closed.
To program this example:
• press the Add soft key.
• press the Wait soft key.
• key in the time for the wait to begin, 2.00, and
press Enter.
• press the close soft key.
The program waits at time 2.00 minutes until input
#1 is closed. If input #1 is already closed at time
2.00 mins, the program will continue. If input # 1 is
not closed, the program will wait. During the time
that the program is waiting, the display will show
the total run time and the time that it has been
waiting.
If a pump is waiting for an input, pressing Cancel
will simulate an input and the program will continue.
Out
In this menu, you can program each of the outputs
in the system to open or close. The out-puts are
numbered 1, 2 and 3 and are used to send signals
to other equipment in the system, for example an
auto sampler or a chart recorder. By having the
output operations as part of the method program,
the same sequence of contacts repeats every time
the method program is run.
There are three pieces of data for this menu.
- Time at which output is operated
- Output number
- Output opened, closed or pulsed
Each of the outputs can be made to open, close or
pulse. Pulse means that the output will change its
current state for 0.6 of a second.

• key in the value for the injection rate, 0.5, and
press Enter.
The injection rate parameter can be changed to
injection time by pressing the Time soft key. There
is a limit of one injection point for each method
program. The maximum injection volume is the
pump head volume multiplied by 100. If you program
a second injection point, it will write over the
existing injection point.

Programming a Method
Operation
At the selected time, the Master 305 starts the
injection pump and automatically lowers the
elution rate in order to keep the total flow rate, and
hence the pressure, constant. The following relationship is applied:
F’e =
F’e :
Fe :
Fi :
Fe - Fi where
the total elution flow rate during injection
the total elution flow rate before injection

A stop-flow injection, generally desired, is then
obtained by selecting Fi 암 Fe.
Reading/Writing/Editing Timed Events
The five different types of timed event have been
explained above. At the end of each event, the
menu gives you five options. These options are
explained below.
Next: displays the next timed event in the sequence. If there are no more events, it displays End of file.
Prev: displays the previous timed event in the
sequence. If there are no more previous
events, it displays Beginning of file.
Add: brings you to the Choose an event type
menu to allow you to add another event to
the present program.
Del:

a safeguard it asks you, Delete this point ?
Press Yes to delete the event or No to return
to the original menu.
End: leaves the software for programming timed
events. The pump displays Solvent consumption in mL for pump A for one complete run of the method program.
Pressing the Next soft key displays in turn the
consumption for the other pumps in the system.
The minimum consumption is < 0.1 mL. The maximum is > 999 mL.
Press Quit to go to the Ready-to-Run Screen. You
have now finished creating a program method file.
Before running a method program, you should
program each of the four safety/error files.
4-30
Operation
The Safety Files are a useful safety feature which
can be used to control the pumping system if a malfunction is detected. It is possible to detect if the
system pressure is too high or too
low, if there has been a power
failure, or if an external sensor has
File Name Function
detected an illegal value (tempera11 Low

ture too high, for example). In this
case, the method program is
12 High
File runs after a high pressure error
stopped, and the relevant Safety File 13 Input File runs if input # 2 is activated
is run. The File number and function 14 Power File runs after a power failure
of each File is listed in this table.
Programming the Safety Files

These programs are created in exactly the same
way as a method program. To program the low
pressure safety file, select file 11 and enter the
sequence of flow rates and input/output operations
that you require when there is a low pressure error.
Similarly, enter a program for the high pressure
safety file, Input# 2 safety file and the power
failure safety file. The Input # 2 contact can be
connected to an external safety device such as a
temperature or pressure measurement system.
An example of simple programs for the high and
low pressure safety files are given in program lists 2
and 3 at the end of this section.
Low Pressure Safety File (File 11)
If the pressure goes below the low pressure limit
the sequence of events is as follows:
• If the low pressure error file (11) contains no
program, the method program will stop and can
not resume until the operator presses the Pause
soft key followed by End.
• If the low pressure error file contains a program,
the method program will link to this file and will
run it. After file 11 is finished, if there is a link to
another file, this new file will start to run. If there
is another low pressure error during file 11, the
pump will stop and can not resume until the
operator presses the Pause soft key followed by
End.
For an example of a Low Pressure safety file refer to
page 4-39, Program List 2.
4-31

Programming the Safety Files
Operation
High Pressure Safety File (File 12)
If the pressure goes above the high pressure limit,
the sequence of events is as follows:
• If the high pressure safety file (12) contains no
program, the pumps stop at the instant the pressure rises above the limit. If the pressure drops
below the limit again, the pump will restart. This
cycle will continue indefinitely.
• If the high pressure safety file contains a program, the pumps stop and wait for the pressure
to drop below the high pressure limit contained
in File 12. When the pressure is below this limit,
file 12 will begin to run. After file 12 is finished, if
there is a link to another file, this new file will
start to run. If there is another high pressure error
during file 12, the pump will stop until the pressure drops below the limit and will then restart.
This cycle will continue indefinitely.
For an example of a High Pressure safety file, refer to
page 4-39, Program List 3.
Input # 2 Safety File (File 13)
When input # 2 is activated, it causes the following
sequence of events:
• If there is no program in File 13, activating input
# 2 will have no effect and the method program
will continue.
• If there is a program stored in File 13, when input
# 2 is activated, File 13 will start. File 13 will start
to run even if the system was not previously
running. If there is a link to another file at the end
of the program, the linked file will start to run.
Power Failure Safety File (File 14)
The power failure safety file will only operate if
there is a power failure while a method program is
running. The sequence of events after a power
failure is as follows:
• If there is no program stored in File 14: after the
power is restored, the program will go back to the
start of the method file and wait for a start input.
4-32
Operation
• If there is a program stored in File 14: after the
power is restored, the program in file 14 will be
run. If there is a link to another program at the
end of file 14, the linked file will start to run. If
the alarm is on, it will sound.
If there is a power failure in the Flow or Dispense
modes, it has the same effect as if the pump was
turned off and turned on again. The screen presented will be the Ready-to-Run Screen of the last
used mode.
Programming the Safety Files
If there is more than one file in the method, i.e.
one file is linked to another, the program will go
back to the beginning of the first file in the
method.

Cond Soft Key
It brings you to the part of the software which is
used to condition the column. You program a ramp
time, the flow rate and gradient. The initial conditions are the existing conditions for the pump, i.e. for
a pump which is not running 0 mL/min and 100%
solvent A. The flow rate and composition programmed should be the flow rate and composition that
is required at the start of the method program that
you are going to use. The solvent flow rate and
composition are then ramped from 0 mL/min and
100% A to the initial composition and flow rate for
your method program.
• press Cond.
• enter the ramping time and press Enter.
• press Flow.
• enter the flow rate for the end of the ramp time.

Pressing Roll displays in turn the time for the ramp,
the flow rate, the proportion of solvent A, B and C
in turn. The proportion of solvents B and C will not
appear if they do not exist.
This part of the software is also used at the end of a
method program to clean the column. The initial
conditions will be the final flow rate and composition which existed at the end of your method
program. You can ramp the flow rate down to 0
mL/min and create a solvent gradient that will
completely clean the column.
The Quit soft key brings you to the Select Menu
Item menu. This gives you access to the pump
setup parameters, the pump I/O parameters and
the method file. Press this key to verify or change
the value of any parameters in these sections.

- Cont will cause the program to continue from
the point where it was paused.
Operation
After a method program has finished, the display
returns to the Ready-to-Run screen.
Running a Method Program
During a method run, the setup parameters and
the method program can be modified. Modify a
parameter in the same way that you program it. If
the flow rate or composition is modified during a
run, the new value will take effect from the
instant it is programmed. If a flow rate is modified
while the pump is running, the new flow gradient
will be between the next programmed point and
the flow rate which existed at the instant the
modification was made.

Programming Examples
Operation
Programming Examples
Two example programs are given below. Before
running these example programs, ensure that the
hydraulic circuit is properly connected.
Example 1
In the example given in List 1, the flow rate will
start at 1 mL/min and increase to 4 mL/min after
2 minutes. The composition will be constant at
100% solvent A. An output will close at 0.00 minutes to start the integrator. The method will only
operate once and will not link to another file when
it is finished. Enter this program following the steps
given Program list 1.
Note that it is necessary to program a flow rate of
0 mL/min at the end of the program to stop the
flow, the flow does not automatically stop when
the program is finished. It will continue with the
last programmed flow rate. To stop the flow at 4.00
minutes you must program a flow rate of 4 mL/min
at 3.99 minutes and 0.00 mL/min. at 4.00 minutes.
Note on Programming Sheet
Appendix G contains a programming sheet which
can be copied. An example of how to use the
programming sheet is also given. The sequence you
should follow is:
• Fill in the File Number and name
• Fill in the SETUP parameters for your system
• Draw the flow rate and composition gradients on
the graphs provided, remembering to mark the
axes
• Fill in the table for Input/Output operations
• Write the programming steps. Finish one section
before going on to the next, i.e. program all of the
flow rate time points before going on to the
composition time points. The 305 software will
arrange all of the time points in the correct sequence.
After writing the method program, it is necessary
to write the programs for the safety/error files.

Example 2
The operation of the method in Example 2
will be as follows.
File # 4 contains the method program. The
flow rate remains constant throughout the
program. At 0.00 minutes the mobile phase
will have a constant flow rate of 3 mL/min
and a composition of 95% A, 5% B and 0%
C. The composition will change to 70% A,
30% B and 0% C in a time of 1 minute. The
composition will stay constant for 1
minute and then return to 95% A, 5% B
and 0% C in a time of 0.5 minutes. The
composition will remain at 5% B until 4.00
minutes. The program will loop and repeat
the same method 3 times and will then
link to File 5.
File 5 will contain a program to set the flow rate to
0 mL/min. The Low pressure and High pressure
safety files that were used in the first example can
also be used for this example. It is not necessary to
reprogram them.
Enter this program by following the steps given in
Program list 4 and 5.
The system is now ready to run. Press
Run.The display will look as opposite.
Press Roll to see the % of A and B changing.
After 2.5 minutes, the program will loop to
start the method a second time. The Loop
Number will change to 2.
At the end of three loops, the program will

Programming Examples
To improve on this basic program, add a wait for
input # 1 timed event at 0.00 min. This means that
the gradient will not start until it receives a signal
from another piece of equipment, for example a
sampler. Only after the sample has been injected
will the gradient start. Program a wait Input # 1 is
closed. To start the program with the wait programmed, connect Pin 1 to Pin 4 on the Input/Output
connector or press Cancel.

Pump Head Maintenance
The check valves and filters can be cleaned. Piston
seals, check valves, piston assemblies, anti-extrusion gaskets and return springs should be replaced
on a regular basis. A maintenance kit is available
for each model of pump head. For details about
maintenance kits and procedures, see the User’s
Guide for your pump head.
The time between each maintenance operation can be viewed
by using the Info soft key in the

For this reason, the following table gives an indication of replacement periods of maintenance parts
according to the type of use, intensive, regular or
occasional. The data in the table below assumes
that the pump is working at half of its maximum
flow rate and pressure. The nature of the liquid

GSIOC Control
GSIOC Features
GSIOC Features
GSIOC stands for Gilson Serial Input Output
Channel. This communications channel links all of
the Gilson modules in a system together. The system
controller controls all of the modules in a system by
sending GSIOC commands to the slave modules, for
example pumps or detectors. Each device connected
to the GSIOC channel is distinguished by a GSIOC
identity number between 0 and 63. The GSIOC
identity number is set by switches inside each
module or by the module’s software. The controller
communicates with one slave device at a time. The
hardware and software requirements to control a
module from a computer using the GSIOC are as
follows:
• A PC running under Windows® 95, 98, NT, or
higher.
• A Gilson interface module, 506C.
• A Gilson HPLC system controller software package.
To get started you must:
For more details consult the
documentation that accompanies the Gilson software.
• Install the Gilson HPLC system controller software
on the computer.
• Connect the computer to the Gilson interface
using the cable provided with the interface.
• Connect the output from the interface to the
Gilson module using a GSIOC cable.
• Start the Gilson HPLC system controller software.

GSIOC Commands
GSIOC Commands
The GSIOC commands can be used to control
Gilson modules directly from a computer or from a
Gilson HPLC system controller software package.
The use of the GSIOC commands is completely
detailed in the 305 technical manual.
305 Commands
Specific 305 GSIOC commands
consider the pump as a set of peripheral devices which can be either
processed by the internal software,
or by the GSIOC bus. There are two
device types: input devices and
output devices.
Command Type
- 305 input devices are: the Keypad,
Contact Inputs, and the Pressure
Input.
- 305 output devices are: the Upper
Line of Display, the Lower Line of
Display, and Contact Outputs.
All commands are detailed below
with their type, mode and function.
Immediate commands have their
response format described. Buffered
command parameters are
documented. Comments are added
where necessary.

to change the addresses of the slave pumps
according to the opposite table.
To change the GSIOC ID number, turn the power
ON. Press <Menu>, <I/O>, then <Prev>. The
display comes “GSIOC Unit ID: 1”. Key in the
desired number (from 2 to 4) and confirm by
hitting <Enter>, then <Quit>.
If a Model 302 or 303 pump is used as a slave
pump, its ID number must also be changed by
setting DIP switches on the Thumbwheel PC
Board. See the related User’s Guide on how to set
ID number.
Appendix B-6
Appendix B
GSIOC Control
GSIOC Commands
Identification of the master pump (pump A) is not
critical. However, if a Model 305 is used with a
computer-based Gilson system, its ID number must
be cleaned in the Setup menu of the software
package (Model 704, 712, 714 or 715).
Command Examples
Example 1: GSIOC Command - Zeroing the
Manometric Module
In order to zero the Manometric Module when
controlling the 305 from a computer-based system
controller, stop all pumps, or pause without flow.
This ensures no actual pressure inside the
Manometric Module. The following GSIOC
commands must be entered:
Send the zeroing K buffered command string. From
the ready-to-run menu, this command string is
made up of: Kdbbce.
This mimics the following key entry sequence:
<Menu>, <I/O>, <Prev>, <Zero>, and <Quit>.
This command can be sent before the run by using
the “GSIOC Control” option of the “Manual”
menu. It can also be added to the method as a
GSIOC event (“Edit” menu, “GSIOC Events” or
“Gilson Instruments” option).

Twin-pump Systems
Appendix C
In each of the systems outlined in this manual there is a maximum of four pumps. The
signals from the controller to the pumps are carried on a communications channel
called the Gilson Serial Input Output Channel, or GSIOC for short. For a single pumping system, all of the pumps are connected in parallel and the controller distinguishes
between any two pumps by a GSIOC identity number which you enter in the software.
Each pump must have a different GSIOC identity number.
If we connect the pumps as shown in the following drawings, we have in effect two or
more parallel pumping systems. The same commands will go to each pump associated
with the same solvent, i.e. pumps A, and A’ will receive the same commands. Pump B
and B’ will receive the same commands etc. Each associated pump will operate in
exactly the same way, one being a mirror image of the other. In this way, we can create
two identical, parallel liquid streams with one controller. The hydraulic outlet tubing
can then be connected together to increase the overall flow rate. Theoretically there is
no limit to the number of pumps that can be connected in parallel, but effectively a
twin system with two liquid streams is the most practical. The advantage of this
arrangement is to be able to use a smaller head and hence work at a higher pressure.
For example, two 25SC heads could be used in parallel to obtain a flow rate of 50
mL/min. The maximum operating pressure would then be 28 MPa instead of a maximum of 14 MPa with a single 50SC head.
The actual flow rate of the combined pumps is the value programmed in the controller
multiplied by the number of pumps in parallel.

For other liquids currently used at
ambient temperatures (20-25 °C), the
following data is given. This data is a
result of experiments done using the 305
pump, the figures are not presented as
physical constants of scientific value.
If no data is available in this chapter for
the liquid you use, and if you wish an
accuracy error within the specifications,
you can experimentally determine a
value to reach this goal.
To do so, use a trial-and-error empirical method.
Select the initial value for Liquid Compressibility
according the following guidelines:
- For an organic solvent, take a value given for the
same, or similar, chemical family.
- For a mixture, including salt aqueous solutions,
take the value of the dominant solvent.
Pump your liquid under high pressure to obtain a
significant error, preferably use a gravimetric
method if you know the density of the liquid.
Then, with a few successive approximations, adjust
the Liquid Compressibility value by assuming a
linear relationship between this parameter and the
resulting error.

To generate the selected flow rate with high accuracy,
maintained under high pressure and for a variety of
liquids, the 305 software adds to complementary
corrections to the basic “piston flow rate”. Defined
from the piston stroke volume only, the piston flow
rate is theoretically accurate at athmospheric pressure only.
The objective flow rate, F, is considered as the sum
of three components:
F = F0 + F1 + F2
F0, the piston flow rate decreases when pressure
increases;
F1, the compensation flow rate for the liquid compressibility, increases with pressure;
F2, the compensation flow rate for all others factors,
also increases with pressure.
Flow Rate Accuracy Principle
Flow Rate Accuracy Principle
Appendix D
The piston flow rate, F0, is defined by:
F0 = N0 VS
with N0, number of piston cycles per unit time; and
VS, piston stroke volume.
The compensation flow rate for the liquid compressibility, F1, is calculated as a function of five variables:
F1 = f1 (F0, VS, VD, P, X)
where VD is the volume of the dead space inside the
compression chamber; P, the operating pressure;
and X, the compressibility of the liquid under the
pressure P.
In the 305 software, X is calculated using the simplified Tait equation:
X= c
P+d
Coeeficient c varies only slightly with the nature of
the liquid. It is a constant included in the software.
Coefficient d is calculated from the Liquid Compressibility at athmospheric pressure, X0 (for P = 0),
entered by the user as a “set-up” parameter. Values
of X0 for some common solvents are tabulated in
the previous page.
Operating pressure, P, is continuously transmitted
to the pump by the Manometric Module (pressure
feedback).
Appendix D-5
Flow Rate Accuracy Principle
Reference Informations
Appendix D-6
Appendix D
The complementary compensation flow rate for all
other factors, F2, is defined as the difference:
F2 = F (F0 + F1)
It was measured and the experimental results were
expressed using a simple function of operating
pressure P:
F2 = f2 (a, b, P)
Coefficients a and b were determined for each pump
head. They are manufacturing constants attached to
the parameter Head Size, a second ‘Setup’ parameter
entered by the user.
All of these factors taken together allow the 305 to
deliver a highly accurate flow rate, independent of
the pump head size, type of liquid and pressure.
