2.1Unpacking and Inspection

Prior to opening the shipping container, inspect it for damage or evidence of mishandling. If it has been damaged or mishandled, notify the carrier before opening the container. Once the container is opened, inspect the contents for damage. Any damage should be reported to the carrier immediately. Save the shipping container. Check the contents against the packing list.

2.2Location/Environment

The preferred environment for the Binary Solvent Delivery Module is normal laboratory conditions. The area should be clean and have a stable temperature and humidity. The specific temperature and humidity conditions are 10 to 30 °C and 20% to 90% relative humidity. The instrument should be located on a stable flat surface with surrounding space for ventilation and the necessary electrical and fluid connections.

2.3Fluid Connections & Priming

There are only four connections to be made.

1.Connect left drawer pump solvent line supplied

2.Connect right drawer pump solvent line supplied

3.Connect line to injection valve from outlet “T”

4.Next, install the self flush. Connect the self flush inlet and outlet (opaque) tubing as shown on the the next page.

Details on the proper installation of tubing and priming of the pump and self flush is shown on the next page.

Binary Solvent Delivery Module Operators ManualPage 1.INTRODUCTION 1.1.1 Pump Features fFast & easy setup Microprocessor advanced control 1.1.2 Wetted Pump Materials1.1.3 Self-FlushingPump Head 1.1.4 Self-Flushand Seal Life It is recommended that the Self Flush feature be used to improve seal life in a number of applications. In particular, as stated above if pumping Buffers, Acids/Bases or any inorganic solution near saturation, the pump should utilize the Self Flush feature. With every piston stroke, an extremely thin film of solution is pulled back past the seal. If this zone is dry without use of Self Flush, then crystals will form with continuous operation, which will ultimately damage the seal Flow Rates 2.INSTALLATION 2.1Unpacking and Inspection2.2Location/Environment 2.3Fluid Connections & Priming SELF-FLUSH PUMPConnect wash solution inlet and outlet tubing opaque to the flush housing as shown 2.5Solvent Preparation 2.5.1 Solvent Out-gassingand Sparging2.4Electrical Connection 2.6.1Mobile Phase Reservoirs 2.5.2 Cavitation2.5.3 Filtration 2.5.4 Initial system pressurization Daily 2.6.2 Self-FlushSolution 2.6.3 Inlet Tubing and Filters2.6.4 Priming the Pump and the Flushing Lines 2.6.6 Long Term Pressure Calibration Accuracy 2.7Preparation for Storage or Shipping 2.7.1Isopropanol Flush2.7.2 Packaging for Shipping 3.OPERATION 3.1.1Control Panel Non-volatileMemory Reset If the pump is operating erratically, there is the possibility that the memory has been corrupted. To reset the memory and restore the pump to its default parameters, press and hold the UP-ARROWbutton when the power is switched on. Release the button when the display reads rES. The parameters stored in non-volatilememory, i.e., the flowrate, the pressure compensation, the voltage/frequency select, the lower pressure limit, and the upper pressure limit will be set to the factory default values. The head type setting is the only parameter not changed by the non-volatilememory reset function. If the firmware is upgraded to a newer version, a non- volatile memory reset will automatically occur the first time the power is switched on 3.6Symbols 3.5Rear Panel Remote Input 4.THEORY OF OPERATION 4.1.1Liquid System Flow Path4.1.2 Pump Cycle 4.1.3 Pulse Damping 4.2.2 DC Power Supply 4.2.1 Microprocessor Control4.2.3 Remote Interfacing 4.2.4 Motor Stall DetectorPage 5.MAINTENANCE 5.1.1 Inlet Filters5.2.1Removing a Pump Head 5.1Filter Replacement 3.Remove the inlet line from the inlet check valve OUTLET FLUSHING CHECK VALVE OUTLET FLUSHING 5.2.2 Cleaning the Pump Head Assembly 1.Inspect the piston seal cavity in the pump head. Remove any foreign material using a cotton swab, or equivalent, and avoid scratching the sealing surfaces. Repeat for the self-flushhousing. Be sure no fibers from the cleaning swab remain in the components 3.If the check valves have been removed, tighten the check valves on stainless steel pumps to 75 inch-poundsor enough to seal at maximum pressure. Do not exceed maximum torque. For Bioclean PEEK pumps, tighten each check valve firmly by hand. Do not go ¼ turn past finger tight 5.2.3 Replacing Piston Seals Lower than normal pressure, pressure variations, and leaks in the pumping system can all indicate possible problems with the piston seal. Depending on the fluid or mobile phase used, piston seal replacement is often necessary after 1000 hours of running time 1.Remove the pump head as described in Section 5.2.1.

Any device capable of providing the proper run/stop logic level, flowrate control frequency, or flowrate control voltage can be used as a remote controlling device for pump operation via this connection. The terminal board connectors can be removed for ease of connecting wires, if desired, by pulling firmly rearward and should be reinserted firmly afterward A.2.2 General Information on Inputs the EVENT 1 terminal and the EVENT 2 and EVENT 3 terminals is affected. EVENT 2 is Normally Closed connected to EVENT 1 until a fault occurs and then opens. EVENT 3 is Normally Open not connected to EVENT 1 until a fault occurs and then closes A.2.4 Run and Stop Inputs The PUMP-RUN, PUMP-STOP,and ENABLE IN inputs operate from an internal 5 VDC source and each one draws approximately 0.008 amps when connected to COM. To activate either the PUMP- RUN, PUMP-STOP,or ENABLE IN input connect it to COM. Any device capable of switching 0.008 amps can be connected between the PUMP-RUN, PUMP-STOP,or ENABLE IN input and COM, such as: a switch contact, a relay contact, an open collector output, an open drain output, or any output with a high logic level output of 3.8 to 6.0 volts and a low logic level output of 0.0 to 0.5 volts. A switch contact or a relay contact is preferred since this type of connection will provide isolation between the pump and the controlling device. The COM terminal is internally connected to the pumps chassis ground and should be connected to the controlling devices ground or zero volt terminal when the controlling device has an open collector output, an open drain output, or any output with logic level output A.2.4 Enable Input When activated ENABLE IN is at a low logic level, the ENABLE IN input disables flowrate control on the front panel and enables flowrate control on the back panel APPENDIX B EZ GRIP FITTING GUIDE Scientific Systems Inc Warranty Statement A-10
