Align Refill Switch Mode: The signal that initiates the refill phase can be displayed during power-up by pressing and holding the PRIME and the UP-ARROW buttons when the power is switched on. Release the buttons when the display displays "rFL". When the slotted disk allows the light beam to pass from the emitter to the detector on the slotted optical switch a pulse will be generated which signals the beginning of refill. When this pulse occurs the three horizontal segments displ

4. THEORY OF OPERATION 4.1 Pump Mechanical Operation 4.1.1 Liquid System Flow Path The flow path of the Binary Solvent Delivery Module starts at the inlet reservoir filter passes through the inlet check valve, then through the pump head, and finally exits through the outlet check valve. 4.1.2 Pump Cycle The pump cycle consists of two phases, the pumping phase, when fluid is metered out of the pump at high pressure, and the refill phase, when fluid is rapidly drawn into the pump. Duri

4.2 Electronic Control 4.2.1 Microprocessor Control The pump is controlled by hybrid microprocessor circuitry which (1) provides control signals to the motor drive circuitry, (2) interfaces with the keyboard/display, (3) receives signals from the refill flag, and (4) provides external input/output (RS-232) interfacing. Firmware programming is stored in an EPROM. An eccentric cam provides refill in a fraction of the full cam cycle. The remaining revolution of the cam provides piston d

Motor Stall Detector press the DOWN-ARROW button and the display will display "OFF". To exit this mode and store the current setting in non-volatile memory, press the RUN/STOP button. The Motor Stall Detector uses a timer to determine if the camshaft has stopped turning or if the refill switch is defective. The timer begins timing after the pump accelerates or decelerates to its set point flow rate. If the Motor Stall Detector has been enabled, and the camshaft stops turning or the

5. MAINTENANCE Cleaning and minor repairs of the Binary pump can be performed as outlined below. NOTE: Lower than normal pressure, pressure variations, or leaks in the pumping system can all indicate possible problems with the piston seal, piston, or check valves. Piston seal replacement could be necessary after 1,000 hours of running time. See Section 5.2.3. 5.1 Filter Replacement 5.1.1 Inlet Filters Inlet filters should be checked periodically to ensure that they are clean and no

1.1 Description of the Binary Solvent Delivery Module The system consists of two Series III high performance metering pumps, in a compact package with pulse dampener and an off-line pressure transducer. The pumps use a drawer system for easy access to internal components for troubleshooting & service. These features allow for: Fast & easy setup: Two inlet connection (from solvent reservoirs) One outlet connection (to injector) All connections accessible from front panel

1.1.4 Self-Flush and 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

2.4 Electrical Connection The system utilizes Universal Switching Power Supply, and will accept voltages from 90 – 260 VAC, 50-60 Hz. WARNING: Do not bypass the safety ground connection as a serious shock hazard could result. 2.5 Solvent Preparation Proper solvent preparation will prevent a great number of pumping problems. The most common problem is bubble formation, which may affect the flow rate consistency. Aside from leaky fittings, the problem of bubble formation ari

2.5.2 Cavitation Cavitation occurs when inlet conditions restrict the flow of solvent and vapor bubbles are formed during the inlet stroke. The key to preventing cavitation is to reduce inlet restrictions. The most common causes of inlet restrictions are crimped inlet lines and plugged inlet filters. Inlet lines with tubing longer than 48" (120 cm) or with tubing of less than 0.085" (2 mm) ID may also cause cavitation. Placing the solvent reservoirs below the pump level also promotes

2.6.2 Self-Flush Solution Self-flush heads require 250-500 mL of flushing solution. See section 1.1.4 for self-flush solution recommendations. A pH indicator that will indicate the concentration of salts in the solution is recommended as a reminder to change the solution. This flush solution should be replaced with a fresh solution weekly to avoid frequent pump maintenance. 2.6.3 Inlet Tubing and Filters The table below shows the inlet tubing and filter used in the Binary Solvent De
