SediGraph III 5120 Service Cabinetry The cabinetry used for the SediGraph III 5120 provides the mounting structure for the fluid module, Analysis module, power supplies, card cage, air flow control, flood control, cabinet interlocks and all interconnecting cables for these assemblies. These assemblies can be further broken down into the following components.
SediGraph III 5120 Service Cabinetry The rear panel is a removable panel which allows access to the 24VDC and the Quad switching power supplies used in the instrument. There are cut-outs in this panel to allow air flow out of the instrument.
Cabinetry SediGraph III 5120 Service Drip Tray and Filter Assembly A drip tray assembly (PN 512/25890/00) is located directly beneath the Fluid Control module. The tray has a handle, which allows an operator to pull the tray assembly out of the instrument.
SediGraph III 5120 Service Fluid module Fluid module The purpose of the fluid module (PN 512/34006/00) is to control the flow of fluid into and out of the instrument for rinsing and cleaning, and to load and circulate sample material. It is located in the lower part of the instrument behind the fluid module cover and consists of the following components.
Fluid module SediGraph III 5120 Service There are four chambers available. • 511/25870/00 (standard chamber) is an aluminum large bore chamber. • 511/25870/02 is a stainless steel large bore chamber used when high pH levels or caustic materials are present.

Fluid module SediGraph III 5120 Service Valve Assemblies Located in the rear of the fluid module, the valve/motor assemblies are used to control the direction and routing of flow through the instrument. They are used in all automatic operations. Waste & Rinse Valve Waste and rinse valves (PN 512/34011/00) are located on the right hand side of the rear of the fluid module.
SediGraph III 5120 Service Fluid module The air valve (PN 512/34012/00) is located on the left hand side of the rear of the fluid module. This valve is unique and cannot be used in another valve position. This valve is used during a rinse operation, or to help rid the cell of bubbles during a fill operation, or whenever the instrument determines there are bubbles in the sample.

SediGraph III 5120 Service Card Cage and PCBs Card Cage and PCBs The card cage is located inside of the cabinetry and is used to hold the cards and backplane PCBs in a central location. It has all of the interconnections needed to interface to the instrument and the operating computer.
Card Cage and PCBs SediGraph III 5120 Service 300/17700/011, i386EX CPU PCB The i386EX CPU card features the i386EX chipset, 128kBytes of NVRAM (Non Volatile Random Access Memory), DRAM (Dynamic Random Access Memory) of up to 32MB with a SIMM socket, 16MB of Boot Block Flash with BIOS configuration, Boot selectable PCMCIA on board Flash, Watchdog timer interfaces with the SediGraph 5120 with a 160 pin DIN connector.
SediGraph III 5120 Service Card Cage and PCBs • The Fluid Control interface has circuitry to control the three valves and two pumps in the Fluid module. The cell pump has an On/Off and direction bit. The cell has speed control through a 12 bit DAC.
Card Cage and PCBs SediGraph III 5120 Service • 2X Logic level inputs (for cell limit switches). There are two logic level (+5VDC) inputs Up/Down. These are active Low signals. A Low signal (from either switch) stops cell movement in the associated direction. There is also an LED for each direction. The LED is lit when the associated switch is active.
SediGraph III 5120 Service Card Cage and PCBs 512/17708/011 Fluid Control PCB The Fluid Control PCB has the controls for the two pumps, three valves, magnetic stirrer and the mixer RTD. This PCB has the following features: • There are two servo control 12-bit DACs and circuitry to control the pump speeds.
Interlock Circuitry SediGraph III 5120 Service Interlock Circuitry The interlock circuitry in the 5120 is very similar in operation to the 5100. • Top panel switches - there are two top panel magnetic interlock switches which have been moved to the mid section of the right hand side panel of the 5120 (due to cabinet construction).
SediGraph III 5120 Service Interlock Circuitry • The X-ray key-switch (located on the front panel) controls whether X-ray generation is allowed or not. When the switch is in the ON position X-rays can be generated, when the key-switch is OFF X-rays cannot be generated.
Interlock Circuitry SediGraph III 5120 Service Analysis Module The Analysis module on the 5120 is basically the same Analysis module used for the 5100 with these exceptions: there is no stepper drive card on the top of the Analysis module assembly, and an updated (electronically) X-ray control board is used.
SediGraph III 5120 Service Interlock Circuitry X-ray tube The X-ray tube (PN 510/57603/00) used in the SediGraph 5120 is the same type as that used on previous SediGraph models. It has the same potentials set for its use, 13,600 Volts for the high voltage accelerant and no more than 3 mA for current is set during calibration.
Page 26
Interlock Circuitry SediGraph III 5120 Service The X-ray tube (PN 510/57603/00) and its floating mounting system are the same type as used in previous models. The high voltage is connected to the X-ray tube by a High Voltage cable (PN 510/60838/00).
SediGraph III 5120 Service Interlock Circuitry The cell tip mechanism has a radius cut into the cell yoke holder that engages a stationary stud on the X-ray tube side of the Analysis module wall. This in turn tilts the cell out (around 45°) to facilitate filling and eliminating air bubbles in the cell assembly.
Power Supplies and Power Entrance SediGraph III 5120 Service Power Supplies and Power Entrance There are four power supplies used in the SediGraph: • X-ray High Voltage • Photo Multiplier Tube high voltage • 24VDC • Quad Switching power supply Two of these supplies are located in the back of the instrument, behind the rear panel.
Page 29
SediGraph III 5120 Service Power Supplies and Power Entrance Access to the high voltage supply is gained by removing the top panel, then removing the internal side mounting panel. Quad switching power supply (PN 003/40002/00) supplies 5VDC, + 15VDC and 24VDC. The 5VDC is used for the front panel Power Led, logic and enables while the + 15VDC is used for the CMOS logic, the 24VDC output goes to the three fans in the instrument.
Power Supplies and Power Entrance SediGraph III 5120 Service Power (AC) is fed to the instrument through an IEC Power entrance rated at 250V and 10Amps. Power is fed to the 24VDC power supply through a circuit breaker integral to the power switch;...
0% Concentration Determination 3. ANALYSIS SEQUENCE The SediGraph III 5120 analyzes particle sizes using the sedimentation method. In this method, particle sizes are determined by knowing the gravity induced falling rates of particles in liquid with known density, temperature and viscosity properties.
SediGraph III 5120 Beamsplit Determination At the beginning of any automatic run, the SediGraph III 5120 determines the exact position of the top of the cell relative to the X-ray beam to establish a known starting point for the cell movement. The SediGraph...
SediGraph III 5120 Service Bubble Determination Bubble Determination During the full-scale scan, the SediGraph III 5120 performs a bubble detection test. Because bubbles in the sedimentation liquid could affect the accuracy of the analysis, the pumping system attempts to remove any detected bubbles before the analysis proceeds.
Equivalent Spherical Diameter (the diameter of a sphere of the same material with the same terminal velocity). The SediGraph III 5120 is designed to provide analysis results which vary by no more than 2 mass percent among samples from a homogenous lot.
