16 Flip the power switch to turn on the device. The on/off switch should light up while the device is turned on. If this is not the case, make sure that the power cord is firmly connected to the device and the power outlet Connecting Additional Modules The modules must be configured individually by the software before they can be used. The procedure is slightly different depending on whether you use the nemesys UserInterface or QmixElements. The exact process is described in the respective software manuals and will be touched on briefly here: In case of the nemesys UserInterface the modules are added to the base module one by one, before being configured. According to this sequence, each module is assigned a number internally. That is the reason devices have to be reset through Remove Dosing Unit before they can be used in a different system. This also resets the assigned number. In QmixElements every module is plugged into the base module, configured and unplugged individually. Once all modules are configured, the system can be assembled. Following, we will describe the mechanical connection of additional modules. To ensure correct function of the overall system, please read and observe the respective section in the associated software manual, before connecting additional modules. IMPORTANT. Please read and observe the respective section of the associated software manual before connecting additional devices. 16 nemesys Hardware Manual

If the module has not been configured, you will be required to perform a reference move during the configuration process. During the reference move the piston holder will move to its front position and be synchronized with the software display. To avoid damage the reference move may only be performed without a syringe. After deactivating the base module the piston holder can be moved by applying some force (e.g. through residual pressure in the system). Therefore, it is sensible to repeat the reference run from time to time. ATTENTION. The reference move must be performed without syringe. Otherwise the device or the syringe may be damaged. CAUTION. Do not touch any moving parts on the device during operation! There is a danger of crushing. nemesys Hardware Manual 25

26 5.4.1 Mounting a Syringe The syringe holder of Low Pressure Syringe Pump allows the use of syringes with outside diameters ranging from 6 to 30 mm and a piston stroke of up to 65 mm. IMPORTANT. Please use high-quality glass syringes with outside diameters ranging from 6 to 30 mm to ensure precise flow rates. Before mounting a syringe to the Low Pressure Syringe Pump, it must be configured and selected in the operating software. The respective process is described in the software manual. You need the volume (scale volume), the nominal stroke (scale length) and the total stroke (piston stroke), which may be different. Scale Length Scale Volume Piston Stroke 26 nemesys Hardware Manual

27 Use the following process to mount a syringe to the Low Pressure Syringe Pump: Loosen the knurled screw of the syringe receptacle. Now you can push the bracket off the pins and lift it up. Disassembly syringe holder Loosen the knurled screw of the piston holder and remove the adapter plate. Lift up the clamping piece.

Place an empty syringe on the remaining base of the syringe holder in such way that the piston touches the piston holder. The syringe position can be varied somewhat by moving the piston holder. For this purpose loosen the screw with a 4 mm Allen wrench. nemesys Hardware Manual 27

28 ATTENTION. To avoid damage, please make sure that the remaining syringe stroke is always the same as or larger than that of the module. Screw Replace the bracket of the syringe holder, insert into the pins and lock the syringe by using the large knurled screw. Replace the clamping piece and insert the adapter plate suitable for the piston diameter in such way that the piston plate is located between piston holder and adapter plate. The piston is locked in place by slightly tightening the knurled screw on the back. Make sure that syringe and syringe piston are in alignment. 28 nemesys Hardware Manual

29 IMPORTANT. The syringes, particularly the seals, are wear parts. Check them on a regular basis and replace them, if necessary Fluidic/Valve The Low Pressure Syringe Pump can be fitted with an optional valve. The valve allows you to switch the syringe connection between your application (outlet) and a reservoir (intake), allowing an automatic refilling of the syringe. Through the software, you can set the valve in such way that it automatically switches to the intake during filling. The three connections are fitted with a ¼ -28 UNF thread and therefore allow the use of common HPLC fittings. Outlet (normally open) Intake (normally closed) Syringe connection A rocker inside the valve (green) connects the syringe port (1) alternatively with the outlet (2) or the intake (3). In the following image the syringe is connected with the outlet (blue), while the intake is closed (red). A FFKM membrane connected to the rocker (shaded in green) seals the fluidic system. This membrane limits the operating pressure of the valve to 3 bar. nemesys Hardware Manual 29

30 ATTENTION. To avoid damaging the valve, please observe the maximum operating pressure of 3 bar. ATTENTION. Before using the valve, please check the chemical resistance of the PEEK housing material and the FFKM sealing material (perfluoroelastomer) against the dosing liquid VALVE INSTALLATION AND REMOVAL The valve can be removed from the device in a few simple steps. This simplifies the fitting of tubes as well as cleaning. It also allows operation without a valve, in cases where it is not needed. To remove the valve press the rocking catch at the plug and remove the plug. When replacing it later please observe the orientation of the plug (the white surface must face the valve, the rocking catch must face away from the valve). 30 nemesys Hardware Manual

45 7.2 Transport and Storage Please do not lift or transport the modules while they are plugged into each other. Transport in assembled state is only permissible when using the original packaging. Use the original packaging for shipping the modules. Please observe the information provided in with respect to storage. ATTENTION. Danger of damaging the device. Do not transport modules while they are plugged into each other. 7.3 Maintenance and Care When used properly, the device is maintenance-free. In case of problems that you cannot fix yourself or that require opening the device, please contact CETONI GmbH to coordinate any further actions. The device may be opened only by CETONI GmbH or authorized service personnel. Failure to adhere to this rule will void the warranty. The software manual includes detailed information about malfunctions with respect to the operating software. Wipe the device with a moist (not wet) cloth in such way that no liquids get into the inside. In case of heavy soiling you may use some detergent or alcohol. 7.4 Hardware Operation Connect the High Pressure Syringe Pump to your base module / system as described in section and the software manual. The High Pressure Syringe Pump only works with an installed safety hood and may only be operated with it in place. Please refer to section for more information about using the safety hood. If the module has not been configured, you will be required to perform a reference move during the configuration process. During the reference move the piston holder will move to its front position and be synchronized with the software display. To avoid damage the reference move may only be performed without a syringe. nemesys Hardware Manual 45

46 After deactivating the base module the piston holder can be moved by applying some force (e.g. through residual pressure in the system). Therefore, it is sensible to repeat the reference run from time to time. ATTENTION. The reference move must be performed without a syringe. Otherwise the device or the syringe may be damaged Mounting the Safety Hood Place the safety hood on the device in such way that the pins slide into the gaps provided for them (blue in image). Push down on the opposite end of the hood until the spring-loaded balls (also shown in blue) settle into the holes provided for them in the hood. To remove the hood, simply reverse this process. Pins Balls CAUTION. Only use the High Pressure Syringe Pump with the mounted safety hood! Do not touch any moving parts on the device during operation! IMPORTANT. If you remove the safety hood during operation, the High Pressure Syringe Pump will stop automatically. 46 nemesys Hardware Manual

47 7.4.2 Fluidic Connections A Swagelok tube fitting is used for fluidic connection. It is suitable for using capillaries made from metal (e.g. stainless steel, titanium) and plastic (e.g. PTFE, PEEK). Please refer to information provided by the respective manufacturer with respect to maximum pressure. The High Pressure Syringe Pump is supplied with two tube fittings for capillaries with an external diameter of 1/16 and 1/18. Following is a description of using the tube fittings: FIRST-TIME INSTALLATION (1) Fully insert the tube / hose into the fitting and against the shoulder; rotate the nut finger-tight. (2) Mark the nut at the 6 o clock position. (3) Tighten the nut three-quarters turn to the 3 o clock position with an open-end wrench DISMANTLING ATTENTION. Release pressure from the system before loosening the fittings. (1) Before dismantling, draw a marker line across the nut and the fitting body. In this way you create a reference for retightening the cap nut to exactly the same position it was in before. (2) Pull out the capillaries. The nut and the ferrules remain on the capillary REASSEMBLY (1) To reassemble, insert the capillary with preassembled ferrules into the fitting body until the front ferrule seats against the fitting body. (2) Rotate the nut with open-end wrench to the previously pulled-up position as indicated by the marks you made before; at this point you will feel a significant increase in resistance. (3) Retighten the nut slightly. Done! You can purchase additional connecting material from Swagelok, such as replacement clamping rings (ordering number SS-100-SET). nemesys Hardware Manual 47

48 IMPORTANT. Only use capillaries specified for the anticipated pressure levels. The supplied 1/16 PEEK tubes are suitable for pressures up to 200 bar. ATTENTION. After connecting, check the tightness of all fluidic connections on a regular basis REPLACING THE CONDUIT FITTING The tube fitting is screwed into the syringe holder and can be loosened or tightened with a 9/16 open end wrench. For this purpose, place the wrench onto the large hexagon nut (not the small one of the cap nut)! There is a metal bushing behind the conduit fitting for sealing purposes. This bushing can remain in the borehole while the conduit fitting is replaced. Firmly tighten the newly mounted conduit fitting to achieve a sealed connection. 48 nemesys Hardware Manual

49 7.4.3 Mounting a Syringe Before mounting a syringe to the High Pressure Syringe Pump, it must be configured and selected in the operating software. The respective process is described in the software manual. You will need the volume (scale volume), the nominal stroke (scale length) and the maximum stroke (piston stroke), which may be different. The scale volume and scale length values are engraved on CETONI stainless steel syringes. Unless otherwise stated, the piston stroke is 60 mm. These values can also be found in the table in section Additional information can be found in the syringe manual. Scale Volume Scale Length Follow these steps to mount a syringe on the High Pressure Syringe Pump: To be able to screw the syringe into the mounting bore while establishing a sealed connection, please insert one of the provided O-rings (3 mm inside diameter and 1.5 mm cord thickness) into the indentation at the syringe outlet (blue in image). nemesys Hardware Manual 49

50 O-ring Position the piston holder in such way as to make sufficient space to screw in the syringe. Remove the safety hood as described in section Screw the syringe into the syringe holder as far as it will go. Put the safety hood back on the device and advance the piston holder until it touches the piston. Take off the safety hood and attach the piston to the piston holder using the knurled screw. 50 nemesys Hardware Manual

51 After putting the safety hood back on, you are ready for dosing. ATTENTION. Before operation, check the resistance of the syringe seal against the dosing medium. If necessary, replace the seal with a seal made from a different material. IMPORTANT. Syringes, and particularly seals, are wear parts. Check them on a regular basis and replace them if necessary Pressure Sensor There is an integrated pressure sensor in the syringe holder of the High Pressure Syringe Pump. This allows the device to stop automatically upon reaching the preset maximum pressure. ATTENTION. Before using the device, check the chemical resistance of wetted materials against the fluid to be metered. nemesys Hardware Manual 51

52 The pressure sensor must be configured in the software before use. The associated process is described in the software manual. For the configuration you will need the pressure range of the sensor (e.g bar) and the range of the output signal (e.g V). These values can be found on the nameplate on the side of the device under sensor: ATTENTION. Configure the pressure sensor before use, to avoid damaging the device or your application. 52 nemesys Hardware Manual

53 8 Accessory Port The Low, Mid and High Pressure Syringe Pumps, are equipped with an accessory port or can be equipped with it as an optional extra. The additional port allows the use of a pressure sensor, for example. The pin assignment of the connector at the module and the wire colors of the connecting cable, which can be purchased from CETONI, can be found in the table on the next page. Of course, you can also purchase ready-made periphery devices from CETONI GmbH. A matching connector plug is also available from Hirose (order number HR10A-10P-12P(73)). The configuration of pressure sensors is described in the software manual. Read and observe the relevant section before connecting a pressure sensor. IMPORTANT. Pin 1 is not assigned at the accessory port of the High Pressure Syringe Pump, because analogue input AI1 is already used for the built-in pressure sensor. nemesys Hardware Manual 53
