1 1 Installing the Pump How to install the quaternary pump
Installing the Pump Site Requirements Site Requirements A suitable environment is important to ensure optimum performance of the quaternary pump. Power Consideration The quaternary pump power supply has wideranging capability (see Table 1 on page 16). It accepts any line voltage in the range described in the above mentioned table. Consequently there is no voltage selector in the rear of the quaternary pump.
Installing the Pump Site Requirements Bench Space The quaternary pump dimensions and weight (see Table 1 on page 16) allow to place the quaternary pump on almost any laboratory bench. It needs an additional 2.5 cm (1.0 inches) of space on either side and approximately 8 cm (3.1 inches) in the rear for the circulation of air and electric connections. If the bench should carry a complete Agilent 1100 Series system, make sure that the bench is designed to carry the weight of all the modules.
Installing the Pump Site Requirements Table 1 Physical Specifications Type Specification Weight 11 kg (25 lbs) Dimensions (height × weight × depth) 140 × 345 × 435 mm (5.5 × 13.
Installing the Pump Unpacking the Quaternary Pump Unpacking the Quaternary Pump Damaged Packaging Upon receipt of your quaternary pump, inspect the shipping containers for any signs of damage. If the containers or cushioning material are damaged, save them until the contents have been checked for completeness and the quaternary pump has been mechanically and electrically checked.

Parts required Pump Power cord, for other cables see text below and “Cable Overview” on page 181 ChemStation and/or Control Module G1323A/B 1 Place the quaternary pump on the bench in a horizontal position. 2 Ensure the power switch on the front of the quaternary pump is OFF (switch stands out).
Installing the Pump Installing the Quaternary Pump NOTE In an Agilent 1100 Series system, the individual modules are connected through CAN cables. The Agilent 1100 Series vacuum degasser is an exception . The vacuum degasser can be connected via the APG remote connector to the other modules of the stack. The AUX output allows the user to monitor the vacuum level in the degasser chamber.
Installing the Pump Installing the Quaternary Pump NOTE The power switch stays pressed in and a green indicator lamp in the power switch is on when the quaternary pump is turned on. When the line power switch stands out and the green light is off, the quaternary pump is turned off. 8 Purge the quarternary pump (see “Priming and Purging the System” on page 28). WAR NI N G To disconnect the quaternary pump from line, unplug the power cord.

2 2 Optimizing Performance How to optimize the quaternary pump to achieve best chromatographic results
Optimizing Performance Hints for Successful Use of the Quaternary Pump Hints for Successful Use of the Quaternary Pump • Always place the solvent cabinet with the solvent bottles on top of the quaternary pump (or at a higher level). • When using salt solutions and organic solvents in the Agilent 1100 Quaternary Pump it is recommended to connect the salt solution to one of the bottom gradient valve ports and the organic solvent to one of the upper gradient valve ports.
Optimizing Performance Hints for Successful Use of the Quaternary Pump Procedure” on page 112).
Optimizing Performance Solvent Information Solvent Information Always filter solvents through 0.4 µm filters, small particles can permanently block the capillaries and valves. Avoid the use of the following steel-corrosive solvents: • Solutions of alkali halides and their respective acids (for example, lithium iodide, potassium chloride, and so on).
Optimizing Performance Prevent Blocking of Solvent Filters Prevent Blocking of Solvent Filters Contaminated solvents or algae growth in the solvent bottle will reduce the lifetime of the solvent filter and will influence the performance of the pump. This is especially true for aqueous solvents or phosphate buffers (pH 4 to 7).
Optimizing Performance Operational Hints for the Vacuum Degasser Operational Hints for the Vacuum Degasser Operational Hints for the Vacuum Degasser If you are using the vacuum degasser for the first time, if the vacuum degasser was switched off for any length of time (for example, overnight), or if the vacuum degasser lines are empty, you should prime the vacuum degasser before running an analysis.
Optimizing Performance Operational Hints for the Multi Channel Gradient Valve (MCGV) Operational Hints for the Multi Channel Gradient Valve (MCGV) In a mixture of salt solutions and organic solvent the salt solution might be well dissolved in the organic solvent without showing precipitations. However in the mixing point of the gradient valve, at the boundary between the two solvents, micro precipitation is possible. Gravity forces the salt particles to fall down.
Optimizing Performance When to use the Continuous Seal Wash Option When to use the Continuous Seal Wash Option Highly-concentrated buffer solutions will reduce the lifetime of the seals and plungers in your quaternary pump. The seal wash option allows to maintain the seal lifetime by flushing the back side of the seal with a wash solvent. The continuous seal wash option is strongly recommended when buffer concentrations of 0.1 Molar or higher will be used for long time periods in the quaternary pump.
Optimizing Performance When to Use Alternative Seals When to Use Alternative Seals The standard seal for the quaternary pump can be used for most applications. However applications that use normal phase solvents (for example, hexane) are not suited for the standard seal and require a different seal when used for a longer time in the quaternary pump. For applications that use normal phase solvents (for example, hexane) we recommend the use of the polyethylene seals, part number 0905-1420 (pack of 2).
Optimizing Performance Optimize the Compressibility Compensation Setting Optimize the Compressibility Compensation Setting The compressibility compensation default setting is 100 × 10-6 /bar for the quaternary pump. This setting represents an average value. Under normal conditions the default setting reduces the pressure pulsation to values (below 1% of system pressure) that will be sufficient for most applications and for all gradient analyses.
Optimizing Performance Optimize the Compressibility Compensation Setting 5 Starting with a compressibility setting of 10 × 10-6 /bar increase the value in steps of 10. Re-zero the integrator as required. The compressibility compensation setting that generates the smallest pressure ripple is the optimum value for your solvent composition.

3 3 Troubleshooting and Test Functions The quaternary pump’s built-in troubleshooting and test functions
Troubleshooting and Test Functions This chapter describes the instrument’s built in troubleshooting and test functions. Status Indicators The quaternary pump is provided with two status indicators which indicate the operational state (prerun, run, and error states) of the quaternary pump. The status indicators provide a quick visual check of the operation of the quaternary pump (see “Status Indicators” on page 45).
Troubleshooting and Test Functions Status Indicators Two status indicators are located on the front of the quaternary pump. The lower left one indicates the power supply status, the upper right one indicates the quaternary pump status.
Power Supply Indicator The power supply indicator is integrated into the main power switch. When the indicator is illuminated (green) the power is ON. When the indicator is off, the module is turned OFF. Otherwhise check power connections, availability of power or check functioning of the power supply.
Troubleshooting and Test Functions Error Messages Error Messages Error messages are displayed in the user interface when an electronic, mechanical, or hydraulic (flow path) failure occurs which requires attention before the analysis can be continued (for example, repair, frit exchange or exchange of consumables required). In the event of such a failure, the red status indicator at the front of the quaternary pump is switched on, and an entry is written into the instrument logbook.
Timeout The timeout threshold was exceeded. Probable Causes • The analysis was completed successfully, and the timeout function switched off the quaternary pump as requested. • A not-ready condition was present during a sequence or multiple-injection run for a period longer than the timeout threshold. Suggested Actions ❏ Check the logbook for the occurrence and source of a not-ready condition. Restart the analysis where required.
Troubleshooting and Test Functions Shut-Down Shut-Down An external instrument has generated a shut-down signal on the remote line. The quaternary pump continually monitors the remote input connectors for status signals. A LOW signal input on pin 4 of the remote connector generates the error message. Probable Causes • Leak detected in another module with a CAN connection to the system . • Leak detected in an external instrument with a remote connection to the system.
Troubleshooting and Test Functions Remote Timeout Remote Timeout A not-ready condition is still present on the remote input . When an analysis is started, the system expects all not-ready conditions (e.g. a not-ready condition during detector balance) to switch to run conditions within one minute of starting the analysis. If a not-ready condition is still present on the remote line after one minute the error message is generated.
Troubleshooting and Test Functions Synchronization Lost Synchronization Lost During an analysis, the internal synchronization or communication between one or more of the modules in the system has failed. The system processors continually monitor the system configuration. If one or more of the modules is no longer recognized as being connected to the system, the error message is generated. Probable Causes • CAN cable disconnected. • Defective CAN cable. • Defective main board in another module.
Troubleshooting and Test Functions Leak Leak A leak was detected in the quaternary pump. The signals from the two temperature sensors (leak sensor and board-mounted temperature-compensation sensor) are used by the leak algorithm to determine whether a leak is present. When a leak occurs, the leak sensor is cooled by the solvent. This changes the resistance of the leak sensor which is sensed by the leak-sensor circuit on the LPM board Probable Causes • Loose fittings. • Broken capillary.
Troubleshooting and Test Functions Leak Sensor Open Leak Sensor Open The leak sensor in the quaternary pump has failed (open circuit). The current through the leak sensor is dependent on temperature. A leak is detected when solvent cools the leak sensor, causing the leak-sensor current to change within defined limits. If the current falls outside the lower limit, the error message is generated. Probable Causes • Leak sensor not connected to the LPM board. • Defective leak sensor.
Troubleshooting and Test Functions Leak Sensor Short Leak Sensor Short The leak sensor in the quaternary pump has failed (short circuit). The current through the leak sensor is dependent on temperature. A leak is detected when solvent cools the leak sensor, causing the leak-sensor current to change within defined limits. If the current increases above the upper limit, the error message is generated. Probable Causes • Defective leak sensor.
Troubleshooting and Test Functions Compensation Sensor Open Compensation Sensor Open The ambient-compensation sensor (NTC) on the LPM board in the quaternary pump has failed (open circuit). The resistance across the temperature compensation sensor (NTC) on the LPM board is dependent on ambient temperature. The change in resistance is used by the leak circuit to compensate for ambient temperature changes. If the resistance across the sensor increases above the upper limit, the error message is generated.
Troubleshooting and Test Functions Compensation Sensor Short Compensation Sensor Short The ambient-compensation sensor (NTC) on the LPM board in the quaternary pump has failed (short circuit). The resistance across the temperature compensation sensor (NTC) on the LPM board is dependent on ambient temperature. The change in resistance is used by the leak circuit to compensate for ambient temperature changes. If the resistance across the sensor falls below the lower limit, the error message is generated.
Troubleshooting and Test Functions Fan Failed Fan Failed The cooling fan in the quaternary pump has failed. The hall sensor on the fan shaft is used by the LPM board to monitor the fan speed. If the fan speed falls below 2 revolutions/second for longer than 5 seconds, the error message is generated. Probable Causes • Fan cable disconnected. • Defective fan. • Defective LPM board. • Improperly positioned cables or wires obstructing fan blades. Suggested Actions ❏ Ensure the fan is connected correctly.
Troubleshooting and Test Functions Open Cover Open Cover The top foam has been removed. The sensor on the LPM board detects when the top foam is in place. If the foam is removed, the fan is switched off, and the error message is generated. Probable Causes • The top foam was removed during operation. • Foam not activating the sensor. • Sensor defective. • Rear of the module is exposed to strong direct sunlight. Suggested Actions ❏ Replace the top foam. ❏ Exchange the LPM board.
Troubleshooting and Test Functions Restart Without Cover Restart Without Cover The quaternary pump was restarted with the top cover and foam open. The sensor on the LPM board detects when the top foam is in place. If the quaternary pump is restarted with the foam removed, the quaternary pump switches off within 30 s, and the error message is generated. Probable Causes • The quaternary pump started with the top cover and foam removed. • Rear of the module is exposed to strong direct sunlight.
Troubleshooting and Test Functions Zero Solvent Counter Zero Solvent Counter Pump firmware version A.02.32 and higher allow to set solvent bottle fillings at the ChemStation (revision 5.xx and higher). If the volume level in the bottle falls below the specified value the error message appears when the feature is configured accordingly. Probable Causes • Volume in bottle below specified volume. • Incorrect setting of limit. Suggested Actions ❏ Refill bottles and reset solvent counters.
Troubleshooting and Test Functions Pressure Above Upper Limit Pressure Above Upper Limit The system pressure has exceeded the upper pressure limit. Probable Causes • Upper pressure limit set too low. • Blockage in the flowpath (after the damper). • Defective damper. • Defective LPM board. Suggested Actions ❏ Ensure the upper pressure limit is set to a value suitable for the analysis. ❏ Check for blockage in the flowpath. The following components are particularly subject to blockage: purge-valve frit.
Troubleshooting and Test Functions Pressure Below Lower Limit Pressure Below Lower Limit The system pressure has fallen below the lower pressure limit. Probable Causes • Lower pressure limit set too high. • Air bubbles in the mobile phase. • Leak. • Defective damper. • Defective LPM board. Suggested Actions ❏ Ensure the lower pressure limit is set to a value suitable for the analysis. ❏ Ensure solvents are degassed. Purge the quaternary pump. ❏ Ensure solvent inlet filters are not blocked.
Troubleshooting and Test Functions Pressure Signal Missing Pressure Signal Missing The pressure signal from the damper is missing. The pressure signal from the damper must be within a specific voltage range. If the pressure signal is missing, the processor detects a voltage of approximately -120mV across the damper connector. Probable Causes • Damper disconnected. • Defective damper. Suggested Actions ❏ Ensure the damper is connected correctly to the LPM board. ❏ Exchange the damper.
Troubleshooting and Test Functions Missing Pressure Reading Missing Pressure Reading The pressure readings read by the pump ADC (analog-digital converter) are missing. The ADC reads the pressure readings from the damper every 1ms. If the readings are missing for longer than 10 seconds, the error message is generated. Probable Causes • Damper not connected. • Defective damper. • Defective LPM board. Suggested Actions ❏ Ensure the damper is connected, clean and seated correctly. ❏ Exchange the damper.
Troubleshooting and Test Functions Pump Configuration Pump Configuration At switch-on, the quaternary pump has recognized a new pump configuration. The quaternary pump is assigned its configuration at the factory. If the gradient valve is disconnected, and the quaternary pump is rebooted, the error message is generated. However, the pump will function as an isocratic pump in this configuration.The error message reappears after each switch-on. Probable Causes • Gradient valve disconnected.
Troubleshooting and Test Functions Valve Fuse Valve Fuse Valve Fuse 0: Channels A and B Valve Fuse 1: Channels C and D The gradient valve in the quaternary pump has drawn excessive current causing the electronic fuse to open. Probable Causes • Defective gradient valve. • Defective connection cable (front panel to LPM board). • Defective LPM board. Suggested Actions ❏ Restart the quaternary pump. If the error message appears again, exchange the gradient valve. ❏ Exchange the connection cable.
Troubleshooting and Test Functions Inlet-Valve Fuse Inlet-Valve Fuse The active-inlet valve in the quaternary pump has drawn excessive current causing the inlet-valve electronic fuse to open. Probable Causes • Defective active inlet valve. • Defective connection cable (front panel to LPM board). • Defective LPM board. Suggested Actions ❏ Restart the quaternary pump. If the error message appears again, exchange the active inlet valve. ❏ Exchange the connection cable. ❏ Exchange the LPM board.
Troubleshooting and Test Functions Valve Failed Valve Failed Valve 0 Failed: valve A Valve 1 Failed: valve B Valve 2 Failed: valve C Valve 3 Failed: valve D One of the valves of the multi-channel gradient valve has failed to switch correctly. The processor monitors the valve voltage before and after each switching cycle. If the voltages are outside expected limits, the error message is generated. Probable Causes • Gradient valve disconnected. • Connection cable (inside instrument) not connected.
Troubleshooting and Test Functions Motor-Drive Power Motor-Drive Power The current drawn by the pump motor exceeded the maximum limit. Blockages in the flow path are usually detected by the pressure sensor in the damper, which result in the pump switching off when the upper pressure limit is exceeded. If a blockage occurs before the damper, the pressure increase cannot be detected by the pressure sensor and the quaternary pump will continue to pump. As pressure increases, the pump drive draws more current.
Troubleshooting and Test Functions Encoder Missing Encoder Missing The optical encoder on the pump motor in the quaternary pump is missing or defective. The processor checks the presence of the pump encoder connector every 2 seconds. If the connector is not detected by the processor, the error message is generated. Probable Causes • Defective or disconnected pump encoder connector. • Defective pump drive assembly. Suggested Actions ❏ Ensure the connector is clean, and seated correctly.
Troubleshooting and Test Functions Inlet-Valve Missing Inlet-Valve Missing The active-inlet valve in the quaternary pump is missing or defective. The processor checks the presence of the active-inlet valve connector every 2 seconds. If the connector is not detected by the processor, the error message is generated. Probable Causes • Disconnected or defective cable. • Disconnected or defective connection cable (front panel to LPM board). • Defective active inlet valve.
Troubleshooting and Test Functions Temperature Out of Range Temperature Out of Range The temperature sensor readings in the motor-drive circuit are out of range. The values supplied to the ADC by the hybrid sensors must be between 0.5 V and 4.3 V. If the values are outside this range, the error message is generated. Probable Causes • Defective LPM board. Suggested Actions ❏ Exchange the LPM board.
Troubleshooting and Test Functions Temperature Limit Exceeded Temperature Limit Exceeded The temperature of one of the motor-drive circuits is too high. The processor continually monitors the temperature of the drive circuits on the LPM board. If excessive current is being drawn for long periods, the temperature of the circuits increases. If the temperature exceeds the upper limit of 95 ºC, the error message is generated.
Troubleshooting and Test Functions Servo Restart Failed Servo Restart Failed The pump motor in the quaternary pump was unable to move into the correct position for restarting. When the quaternary pump is switched on, the first step is to switch on the C phase of the variable reluctance motor. The rotor should move to one of the C positions. The C position is required for the servo to be able to take control of the phase sequencing with the commutator.
Troubleshooting and Test Functions Pump Head Missing Pump Head Missing The pump-head end stop in the quaternary pump was not found. When the quaternary pump restarts, the metering drive moves forward to the mechanical end stop. Normally, the end stop is reached within 20 seconds, indicated by an increase in motor current. If the end point is not found within 20 seconds, the error message is generated.
Troubleshooting and Test Functions Index Limit Index Limit The time required by the plunger to reach the encoder index position was too short (quaternary pump). During initialization, the first plunger is moved to the mechanical stop. After reaching the mechanical stop, the plunger reverses direction until the encoder index position is reached. If the index position is reached too fast, the error message is generated. Probable Causes • Irregular or sticking drive movement. • Defective pump drive assembly.
Troubleshooting and Test Functions Index Adjustment Index Adjustment The encoder index position in the quaternary pump is out of adjustment. During initialization, the first plunger is moved to the mechanical stop. After reaching the mechanical stop, the plunger reverses direction until the encoder index position is reached. If the time to reach the index position is too long, the error message is generated. Probable Causes • Irregular or sticking drive movement. • Defective pump drive assembly.
Troubleshooting and Test Functions Index Missing Index Missing The encoder index position in the quaternary pump was not found during initialization. During initialization, the first plunger is moved to the mechanical stop. After reaching the mechanical stop, the plunger reverses direction until the encoder index position is reached. If the index position is not recognized within a defined time, the error message is generated. Probable Causes • Disconnected or defective encoder cable.
Troubleshooting and Test Functions Stroke Length Stroke Length The distance between the lower plunger position and the upper mechanical stop is out of limits (quaternary pump). During initialization, the quaternary pump monitors the drive current. If the plunger reaches the upper mechanical stop position before expected, the motor current increases as the quaternary pump attempts to drive the plunger beyond the mechanical stop. This current increase causes the error message to be generated.
Troubleshooting and Test Functions Initialization Failed Initialization Failed The quaternary pump failed to initialize successfully within the maximum time window. A maximum time is assigned for the complete pump-initialization cycle. If the time is exceeded before initialization is complete, the error message is generated. Probable Causes • Blocked active inlet valve. • Defective pump drive assembly. • Defective LPM board. Suggested Actions ❏ Exchange the active inlet valve.
Troubleshooting and Test Functions Wait Timeout Wait Timeout When running certain tests in the diagnostics mode or other special applications, the pump must wait for the plungers to reach a specific position, or must wait for a certain pressure or flow to be reached. Each action or state must be completed within the timeout period, otherwise the error message is generated. Possible Reasons for a Wait Timeout • Pressure not reached. • Pump channel A did not reach the delivery phase.
Pressure Test Description The pressure test is a quick, built-in test designed to demonstrate the pressure-tightness of the system. The test should be used when problems with small leaks are suspected, or after maintenance of flow-path components (e.g. pump seals, injection seal) to prove pressure tightness up to 400 bar. The test involves monitoring the pressure profile as the pump runs through a predefined pumping sequence.
Troubleshooting and Test Functions Pressure Test with a flow rate of 510 µl/min and stroke of 100 µl. The pump continues to pump until a system pressure of 390 bar is reached. Step 2 When the system pressure reaches 390 bar, the pump switches off. The pressure drop from this point onwards should be no more than 2 bar/minute.
Troubleshooting and Test Functions Running the Pressure Test Running the Pressure Test Tools required ¼-inch” wrench Parts and materials required Blank nut, 01080-83202 Isopropanol, 500 ml Running the test from the ChemStation 1 Select the pressure test from the test selection box in the Diagnosis screen. 2 Start the test and follow the instructions.
Troubleshooting and Test Functions Running the Pressure Test Once the test is started, the pump moves the plungers into the start position. When the plungers are in position, the user interface prompts you to close the purge valve, and continue the test. 7 Close the purge valve, select continue on the control module and press Enter to start the test. The control module displays a graphical representation of the pressure.
Troubleshooting and Test Functions Evaluating the Results Evaluating the Results The sum of all leaks between the pump and the blank nut will be indicated by a pressure drop of >2 bar/minute at the plateau. Note that small leaks may cause the test to fail, but solvent may not be seen leaking from a module. NOTE Please notice the difference between an error in the test and a failure of the test! An error means that during the operation of the test there was an abnormal termination.
Troubleshooting and Test Functions Evaluating the Results Potential Causes of Pressure Test Failure After isolating and fixing the cause of the leak, repeat the pressure test to confirm the system is pressure tight. Potential Cause (Pump) Corrective Action Purge valve open. Close the purge valve. Loose or leaky fitting. Tighten the fitting or exchange the capillary. Damaged pump seals or plungers. Run the leak test to confirm the leak. Loose purge valve. Tighten the purge valve nut (14 mm wrench).
Troubleshooting and Test Functions Leak Test Leak Test Description The leak test is a built-in troubleshooting test designed to demonstrate the leak-tightness of the pump. The test should be used when problems with the pump are suspected. The test involves monitoring the pressure profile as the pump runs through a predefined pumping sequence. The resulting pressure profile provides information about the pressure tightness and operation of the pump components.
Troubleshooting and Test Functions Leak Test Ramp 1: After initialization, plunger 2 is at the top of its stroke. The test begins with plungerplunger 1 delivering with a stroke length of 100µl and a flow of 153µl/min. The plunger sequence during the pressure ramp is 1-2-1-2. The pressure increase during this phase should be linear. Pressure disturbances during this phase indicate larger leaks or defective pump components.

6 6 Introduction to the Quaternary Pump An introduction to the pump, instrument overview, theory of operation, external communication and internal connectors
Introduction to the Quaternary Pump Introduction to the Quaternary Pump Introduction to the Quaternary Pump The quaternary pump comprises a solvent cabinet, a vacuum degasser and a four-channel gradient pump. The four-channel gradient pump comprises a high-speed proportioning valve and a pump assembly. It provides gradient generation by low pressure mixing. Degassing is a must for a low-pressure gradient system therefore the Agilent 1100 Series vacuum degasser is part of the quaternary pump system.
Introduction to the Quaternary Pump Overview Overview The quaternary pump is based on a two-channel, dual plunger in-series design which comprises all essential functions that a solvent delivery system has to fulfill. Metering of solvent and delivery to the high-pressure side are performed by one pump assembly which can generate pressure up to 400 bar. Degassing of the solvents is done in a vacuum degasser and solvent compositions are generated on the low-pressure side by a high-speed proportioning valve.
Introduction to the Quaternary Pump Overview How does the Pump Work? The liquid runs from the solvent reservoir through the degasser to the MCGV and from there to the active inlet valve. The pump assembly comprises two substantially identical plunger/chamber units. Both plunger/chamber units comprise a ball-screw drive and a pump head with one sapphire plunger for reciprocating movement in it. A servo-controlled variable reluctance motor drives the two ball-screw drives in opposite directions.
Introduction to the Quaternary Pump Overview Figure 42 Principle of the Quaternary Pump Damper Chamber 2 Chamber 1 Purge valve To mixing chamber Inlet valve Outlet valve To waste From solvent bottle Seal Plunger 1 Plunger 2 Ball screw drive Gear Motor with encoder When turned on, the quaternary pump runs through an initialization procedure to determine the upper dead center of the first plunger.
Introduction to the Quaternary Pump Overview chamber is pressed through the outlet ball valve into the second chamber. The second plunger draws in half of the volume displaced by the first plunger and the remaining half volume is directly delivered into the system. During the drawing stroke of the first plunger, the second plunger delivers the drawn volume into the system.
Introduction to the Quaternary Pump Overview With a compressibility value set the processor calculates a compensation volume, that is depending on the backpressure in the system and the selected compressibility. This compensation volume will be added to the normal stroke volume and compensates the previous described loss of volume during the delivery stroke of the first plunger.
Introduction to the Quaternary Pump Electrical Connections Electrical Connections • The GPIB connector is used to connect the pump with a computer. The address and control switch module next to the GPIB connector determines the GPIB address of your pump. The switches are preset to a default address (Table 31 on page 218 or Table 35 on page 223). This address is recognized at powercycling the module. • The CAN bus is a serial bus with high speed data transfer.
Introduction to the Quaternary Pump Electrical Connections Figure 43 Electrical Connections Security lever Slot for interface board Analog pressure, 2mV/bar APG Remote RS-232C CAN GPIB Power Configuration switch WAR NI N G To disconnect the quaternary pump from line, unplug the power cord. The power supply still uses some power, even if the power switch on the front panel is turned off.
Introduction to the Quaternary Pump Instrument Layout Instrument Layout The industrial design of the module incorporates several innovative features. It uses Agilent’s E-PAC concept for the packaging of electronics and mechanical assemblies. This concept is based upon the use of expanded polypropylene (EPP) layers foam plastic spacers in which the mechanical and electronic boards components of the module are placed.
Introduction to the Quaternary Pump Early Maintenance Feedback (EMF) Early Maintenance Feedback (EMF) Maintenance requires the exchange of components in the flow path which are subject to mechanical wear or stress. Ideally, the frequency at which components are exchanged should be based on the intensity of usage of the instrument and the analytical conditions, and not on a predefined time interval.
Introduction to the Quaternary Pump Early Maintenance Feedback (EMF) Using the EMF Counters The user-settable EMF limits for the EMF counters enable the early maintenance feedback to be adapted to specific user requirements. The wear of pump components is dependent on the analytical conditions, therefore, the definition of the maximum limits need to be determined based on the specific operating conditions of the instrument.
Introduction to the Quaternary Pump The Electronics The Electronics The electronics are comprised of four main components: • The low pressure pump main board (LPM), see page 210. • Power supply, see page 228. Optional: • Interface board (BCD/external contacts), see page 216. • Interface board (LAN), see page 217.
Introduction to the Quaternary Pump The Low-Pressure Pump Main Board (LPM) The Low-Pressure Pump Main Board (LPM) The board controls all information and activities of all assemblies within the quaternary pump. The operator enters parameters, changes modes and controls the quaternary pump through interfaces (CAN, GPIB or RS-232C) connected to the user-interfaces. Figure 45 and Figure 46 show the block diagrams of this board.
Introduction to the Quaternary Pump The Low-Pressure Pump Main Board (LPM) Fan Drive The fan speed is controlled by the main processor depending on the internal heat distribution in the quaternary pump. The fan provides a PWM signal which is proportional to its speed. This fan status signal is used for diagnostics. Electronic Fuses The valve circuits are electronically fused on the board.

Introduction to the Quaternary Pump Firmware Description Firmware Description The firmware of the instrument consists of two independent sections: • a non-instrument specific section, called ‘resident system’, • an instrument specific section, called ‘main system’. Resident System This resident section of the firmware is identical for all Agilent 1100 series modules.
Introduction to the Quaternary Pump Firmware Description Firmware Updates Firmware updates can be done using your user interface: • handheld control module with files from a PC-card or • Agilent ChemStation with files from floppy disk The file naming conventions are: xxxx-vvv.DLB, where xxxxis the product number, e.g. 1311 for the G1311A QuaternaryPump), and vvvis the revision number, for example 200 is revision 2.00. For instructions refer to your user interface.
Introduction to the Quaternary Pump Optional Interface Boards Optional Interface Boards The Agilent 1100 Series modules have one optional board slot that allows to add an interface board to the modules. Table 29 Optional Interface Boards Description Part Number BCD Board G1351-68701 Fuse 250 mA (four are on the board) 2110-0004 LAN Board (see next page for details) BCD Board The BCD board provides a BCD output for the bottle number of the Agilent 1100 Series autosampler and four external contacts.
Introduction to the Quaternary Pump Optional Interface Boards LAN Board The HP LAN board is actually an HP JetDirect card, which is a network interface card used in HP printers. NOTE One board is required per Agilent 1100 stack. If the Agilent 1100 stack has a DAD, then the DAD MUST be the module used for LAN board installation. If no DAD is present a pump should be used for the LAN board installation.

Introduction to the Quaternary Pump Agilent 1100 Series Interfaces connector. The RS-232C is designed as DCE (data communication equipment) with a 9-pin male SUB-D type connector.
Introduction to the Quaternary Pump Setting the 8-bit Configuration Switch Setting the 8-bit Configuration Switch The 8-bit configuration switch is located next to the GPIB connector. Switch settings provide configuration parameters for GPIB address, serial communication protocol and instrument specific initialization procedures. Figure 50 8-bit Configuration Switch 1 factory setting is shown for quaternary pump 0 .
Introduction to the Quaternary Pump Setting the 8-bit Configuration Switch In the non-volatile memory the parameters are kept, regardless of whether you turn the instrument off and on again. They will be kept until the same set of parameters is subsequently changed and power is reset. All other previously stored configuration settings will still remain in the non-volatile memory.
Introduction to the Quaternary Pump Setting the 8-bit Configuration Switch Switches 1 in down and 2 in up position define that the RS-232C parameters will be changed. Once the change has been completed, the instrument must be powered up again in order to store the values in the non-volatile memory.

Returning the switches 1 and 2 to other positions (other than being both up) will allow for normal operation. CA UT IO N A forced cold start erases all methods and data stored in non-volatile memory.
Introduction to the Quaternary Pump Setting the 8-bit Configuration Switch Switches 1 and 2 do not force storage of this set of parameters in non-volatile memory. Returning the switches 1 and 2 to other positions (other than being both up) will allow for normal operation. If you use the following switch settings and power the instrument up again, the instrument firmware stays in the resident part, that is, it is not operable as a quaternary pump.
Introduction to the Quaternary Pump The Main Power Supply Assembly The Main Power Supply Assembly The main power supply comprises a closed assembly (no component-level repair possibility). The power supply provides all DC voltages used in the quaternary pump. The line voltage can vary in a range from 100 – 120 or 220 – 240 volts AC ± 10 % and needs no manual setting.
Introduction to the Quaternary Pump The Main Power Supply Assembly When overload conditions occur, the power supply turns off all output voltages. Turning the line power off and on again resets the power supply to normal operation if the cause of the overload condition has been removed. An over-temperature sensor in the main power supply is used to turn off output voltages if the temperature exceeds the acceptable limit (for example, if the cooling fan of the quaternary pump fails).
