Intended Use Intended Use Note: Only use the device for applications that fall within the range of the intended use. Otherwise, the protective and safety equipment of the device could fail. Device Overview The HPLC pumps P 4.1S/ P 2.1S with pump heads can be used as feed pumps or dosing pumps in analytical or preparative applications.
Intended Use Legend LAN port Opening of the fan Pin header for remote control CE mark Power connection - bushing Serial number Hole for the ground connection RS-232 port External devices like computers, fraction collectors, etc. can be connected in 3 different ways: ...
Intended Use Piston backflushing High physical and chemical stability Flexible control with LAN connection, RS-232 interface, and analog control signals Control with chromatography software Options A pump in combination with another pump can be used to set up a binary high pressure gradient system.
Intended Use Eluents Even small quantities of other substances, such as additives, modifiers, or salts can influence the durability of the materials. Note: The list of selected solvents was compiled based on research in the perti- nent literature and is only a recommendation. If there is any doubt, contact the Technical Support of the manufacturer.

Unpacking and Setup Contact data Explanation ERROR IN/OUT TTL-compatible input min. 10 mA Low active After receiving a signal (e. g. short-circuit to ground) from an external device, an error message appears and the device stops. ANALOG IN Flow rate is controlled through external control voltage (0–10 V).
Unpacking and Setup Process Figure 1. Place the terminal strip on a suitable surface. 2. Push the depressor tool into the opening on the upper side. 3. Continue pushing the depressor tool down and lead the cable into the front end of the termi- nal strip.
Unpacking and Setup In case you use an USB-to-COM box, the option "Allow the computer to turn off ths device to save power" in the devicemanager must be deactivated for all USB hosts. Only for Windows 7: For the network adapter, the option "Allow the com- puter to turn off this device to save power"...
Unpacking and Setup There is a patch cable for each device and the computer. Process: 1. Use the patch cable to connect the router and the computer. Repeat this step to connect all devices. 2. Use the power supply to connect the router to the mains power system. Configuring the Router The router is preset at the factory.
If the supplied power adapter is used, then the ground connection remains unused. Please contact the technical support of KNAUER, if the pump along with other devices should be connected to the power supply with a 6-prong power adapter; a pump needs to be grounded exclusively.
Operation 3. Switch on the power adapter. 4. Wait until the pump has completed the self-test. Result: After the device is switched on, the display shows Pump and the Firmware version. The device performs a self-test. After all tests have been successfully completed, the status of the pump with its current flow rate is displayed.
Operation Process Figure 1. Prime liquid with the syringe. 2. Hold down start/stop key until flushing starts. Control The pump can be operated in two ways: Using the buttons at the device ® ® Using the software ClarityChrom or ChromGate Note: Operator errors and clogged capillaries can cause high pressure spikes.

Operation dent on the compressibility and the viscosity of the used solvent and on the pump. Therefore, it must be determined individually for each pump. The flow rate can be altered while the pump is in operation. Practical Tip: Hold down both arrow keys to expedite changing the values. Process Figure 1.

(e. g. if leaking). The pump is preset to a standard value for the maximum power consumption. KNAUER recommends that with smaller flow rates the standard value for the maximum power consumption should be insignificantly decreased.
Operation 3. When the cursor flashes, use the arrow keys again to set the value for the maximum power consump- Fig. 15 Minimum power consumption tion. 4. Hold down left arrow key. Press right arrow key once. 5. When the cursor flashes, use the arrow keys again to set the value for the minimum power consump- Fig.
