AX43x is used with the TB4 and AC400* Series of insertion, immersion and flow-through, four-electrode conductivity cells providing measurements with exceptional accuracy and performance.AX400 Series analyzers are available for either wall-/pipe- or panel-mounting and are rated to IP66/NEMA 4X.* Check with factory for availability.High Functionality as StandardAll versions are supplied with two, fully-isolated current outputs as standard, that can be assigned to the measured parameter,sample temperature or any appropriate calculated variables.Three programmable relay set points are available which can also be assigned as required.Innovative features such as a power saving display and a diagnostic current output option all contribute to a low cost of ownership.Plug-and-Produce Expanded ControlAn advanced function card provides an additional two current outputs and two further alarm relays that can be assigned to either measured values or sample temperature.ABB Plug-and-Produce software automatically reconfigures the analyzer if an option board is added later. No user programming is necessary.A real-time clock and logbook are also included making the full-facility versions extremely powerful and versatile.Significantly Reduced Maintenance CostsThe AX400 Analyzers are supplied as standard for 85 to 265V AC operation. There are no inner switches to set.They can also be provided for 24V AC, or 12 to 30V DC, supply and recognize automatically which of the two supplies is being used. 24V DC operation reduces maintenance costs significantly by negating the need for costly, yearly safety tests to ensure compliance with safety procedures.Energy Saving DisplayThe backlit display has been designed to operate in all types of environments and shows both the measured parameter(s) and,on a separate 16-character display line, diagnostic and computed information.On dual-input analyzers both measured parameters are displayed simultaneously.For conservation of energy, the backlight can be set to switch off automatically after 60s of inactivity.Backlight Can be Set to Switch-off When InactiveEasy Access Installation TerminalsE asy access to the terminations ensures rapid and cost-effective installation. The wall-/pipe-mount version has been designed to ensure that cable connection is simple and convenient. Ingress protection of the electronics section is retained even when the terminal compartment is opened.AX400 Termination Chamber Makes Access EasyAX400 OutputsSingle and Dual Input Analyzers for High-level Conductivity AX430, AX433, AX413 and AX436SS/AX4CO4_53Advanced Conductivity and Concentration MonitoringIn addition, these analyzers enable operation directly in terms of concentration: 0 to 15% NaOH, 18% HCl, 20% H 2SO 4,40% H 3PO 4, 20% NaCl and user-defined. This is particularly suited for strength-monitoring of ion exchange regenerant acid and alkali.Cost-effective Control of CIP PlantAX43x conductivity analyzers measure up to 1,999mS cm –1enabling operation in the majority of high concentration processes. Automatic and manual temperature compensations enable effective measurements up to 300°C (572°F).Single and Dual Input Analyzers for High-level Conductivity AX430, AX433, AX413 and AX436SS/AX4CO4_54AX436 Combined Conductivity and pHThe AX436 version measures conductivity and pH with the same analyzer. The option board provides the capability to retransmit conductivity, pH and both sample temperatures. This is particularly useful in the paper industry, reducing the investment in separate instruments, for example, when used on white water or the head box.Simultaneous Conductivity and pH MeasurementDual Input MeasurementSingle and Dual Input Analyzers for High-level Conductivity AX430, AX433, AX413 and AX436SS/AX4CO4_55Long-dose Alarm FunctionAn important diagnostic capability incorporated in AX43x analyzers is the long-dose alarm function. This is useful for occasions when faults occur in the dosing system.The analyzers can be configured to provide an alarm if a set point has not been reached within a specified time. This valuable facility provides a warning that could indicate a loss of dosing chemicals, a leakage or a costly pump failure.Long-dose Alarms Warns of Dosing Systems FaultsInitial Charge FunctionIn some applications, fresh dosing chemical reagent is made up every few days. For example, in bottle-washing plants the caustic solution can become dirty and must be replaced regularly. In the case of a new charge, i.e. making up a fresh reagent dilution, a general long-dose alarm could be initiated before the reagent had attained the correct concentration.AX43x analyzers provide a simple solution by having a pre-configurable Initial Charge function. A simple button press from Initial Charge Function When Making Fresh ReagentSingle and Dual Input Analyzers for High-level Conductivity AX430, AX433, AX413 and AX436SS/AX4CO4_56AX430 Integral P, PI and PID ControlThe single input AX430 analyzers incorporate three-term PID Control, offering three modes of sophisticated control: analog,pulse length (time proportional) and pulse frequency. These are supplied as standard and can be operated in direct- or reverse-acting mode, depending upon the application.Auto/Manual and Bumpless TransferAn auto/manual feature is incorporated for rapid manual access to the control functions. The controller facilitates bumpless transfer between manual and auto modes, providing the measured variable is within the proportional band and some integral action time has been programmed.Current Output Proportional ControlIn this case, the control signal is provided by the 4 to 20mA output of AX430 analyzers rather than using the alarm/control contacts. The magnitude of the current output changes in proportion to the deviation from set point. This method is used generally with motorized valves or when controlling the speed of dosing pumps with a 4 to 20mA proportional input.Pulse-frequency Proportional ControlImpulse pumps dosing chemical reagents are controlled easily by the AX430 analyzer’s pulse-frequency proportional control output. In this case, the pulse length of the alarm/control contact is fixed and the frequency of the delivered pulses increases in proportion to the system error, as set by the proportional band.Diaphragm metering pumps must have a remote pulse input capability in order to utilize this function.Pulse-frequency control in the AX430 analyzer operates by pulsing a relay on for 300ms and off for a period of time determined by the pulse frequency. The pulse frequency (PFr) is adjustable between 1 and 120 pulses per minute. The greater the difference between the measured variable and the set point,the greater the pulse frequency.ExampleIf the pulse frequency is set at 120 pulses per minute and the percentage output is 100% then the pulse rate is 2 pulses per second. If the percentage output is reduced to 50%, the pulse rate falls to one pulse per second.Pulse-frequency Proportional ControlPower Failure RecoveryIn the event of a power failure the user can configure the control mode to be Auto, Manual or Last. This optimizes control conditions on power-up to ensure rapid recovery of process control.Time Proportioning ControlOutput = 0%Output = 50%Output = 100%Energized De-energized EnergizedDe-energizedPermanently De-energized Pulse Frequency = 120 pulses per minute0.3s 0.7ms0.3s 0.2s 0.3s 0.2sSingle and Dual Input Analyzers for High-level Conductivity AX430, AX433, AX413 and AX436SS/AX4CO4_57SpecificationConductivityRangeConductivity Programmable 0.000 to 1999mScm –1(uncompensated)Concentration0.000 to 1.999 digits (user configurable)Selectable concentration ranges 0 to 15% NaOH0 to 18% HCl 0 to 20%H 2SO 40 to 40% H 3PO 40 to 20% NaCl User-defined table Temperature–20 to 300°C (–4 to 572°F )Sensor Full Scale Measurement Ranges(a) TB4 Group A and AC400 cells 0 to 1,999mS cm –1(uncompensated)(b) TB4 Group B cells 0 to 1,999μS cm –1(uncompensated)Minimum span (a)TB4 Group A and AC400 cells 100.0μS cm –1(b)TB4 Group B cells 10.00μS cm –1Concentration 5% of the maximum set concentration range Temperature10°C (50°F)Note .

It is designed for portable devices with multiple power supply options including wall adaptors, car battery adaptors and USB ports.The L TC4361 controls an external N-channel MOSFET in series with the input power supply. During overvoltage transients, the L TC4361 turns off the MOSF ET within 1μs, isolating downstream components from the input supply. Inductive cable transients are absorbed by the MOSFET and load capacitance. In most applications, the L TC4361 provides protection from transients up to 80V without requiring transient voltage suppressors or other external components.The L TC4361 has a delayed start-up and adjustable dV/dt ramp-up for inrush current limiting. A PWRGD pin provides power good monitoring for V IN . The L TC4361 features a soft shutdown controlled by the ON pin and drives an optional external P-channel MOSF ET for negative voltage protection.

An additional ramp circuit limits the GATE ramp rate when turning on to 3V/ms. For slower ramp rates, connect an external capacitor from GATE to GND. An internal clamp limits GATE to 6V above the OUT pin voltage. An internal GATE high comparator controls the PWRGD pin. GATEP: Gate Drive for External P-Channel MOSFET.

An internal 2M resistor connects this pin to ground. Connect to IN if not used.GND: Device Ground.IN: Supply Voltage Input. Connect this pin to the input power supply.

The small form factor is accompanied by low absolute maximum voltage ratings. The sensitive electronics are susceptible to damage from transient or DC overvoltage conditions from the power supply. Failures or faults in the power adaptor can cause an over-voltage event. So can hot-plugging an AC adaptor into the power input of the mobile device (see L TC Application Note 88). Today’s mobile devices derive their power supply or recharge their internal batteries from multiple alternative inputs like AC wall adaptors, car battery adaptors and USB ports. A user may unknowingly plug in the wrong adaptor, damaging the device with a high or even a negative power supply voltage.The L TC4361 protects low voltage electronics from these overvoltage conditions by controlling a low cost external N-channel MOSFET confi gured as a pass transistor. At power-up (V IN > 2.1V), a start-up delay cycle begins. Any overvoltage condition causes the delay cycle to continue until a safe voltage is present. When the delay cycle completes, an internal high side switch driver slowly ramps up the MOSFET gate, powering up the output at a controlled rate and limiting the inrush current to the output capacitor. If the voltage at the IN pin exceeds 5.8V (V IN(OV)), GATE is pulled low quickly to protect the load. The incoming power supply must remain below 5.7V (V IN(OV) – ΔV OV) for the duration of the start-up delay to restart the GATE ramp-up.A sense resistor placed between IN and SENSE implements an overcurrent protection with a 50mV trip threshold and a 10μs glitch fi lter. After an overcurrent, the L TC4361-1 latches off while the L TC4361-2 restarts following a 130ms delay.The L TC4361 has a CMOS compatible ON input. When driven low, the part is enabled. When driven high, the external N-channel MOSFET is turned off and the supply current of the L TC4361 drops to 1.5μA. The PWRGD pull-down releases during this low current sleep mode, UVLO, overvoltage or overcurrent and the subsequent 130ms start-up delay. After the start-up delay, GATE starts its slow ramp-up and ramps higher than V GATE(TH) to trigger a 65ms delay cycle. When that completes, PWRGD pulls low.The L TC4361 has a GATEP pin that drives an optional external P-channel MOSFET to provide protection against negative voltages at IN.7436112f8436112fThe typical L TC4361 application protects 2.5V to 5.5V systems in portable devices from power supply overvolt-age. The basic application circuit is shown in Figure 1. Device operation and external component selection is discussed in detail in the following sections.APPLICATIONS INFORMATIONFigure 1. Protection from Input Overvoltage and OvercurrentM1R SENSE OUT V IN 5VThe GATE ramp rate is limited to 3V/ms. V OUT follows at a similar rate which results in an inrush current into the load capacitor C OUT of:I INRUSH =C OUT •dV GATEdt=C OUT •3 mA/µF []The servo loop is compensated by the parasitic capaci-tance of the external MOSFET . No further compensation components are normally required. In the case where the parasitic capacitance is less than 100pF, a 100pF compensation capacitor between GATE and ground may be required.An even slower GATE ramp and lower inrush current can be achieved by connecting an external capacitor , C G , from GATE to ground. The voltage at GATE then ramps up with a slope equal to 10μA/C G [V/s]. Choose C G using the formula:C G =10µA I INRUSH •C OUTOvervoltageWhen power is fi rst applied, V IN must remain below 5.7V(V IN(OV) – ΔV OV ) for more than 130ms before GATE is ramped up to turn on the MOSFET . If V IN then rises above 5.8V (V IN(OV)), the overvoltage comparator activates the 30mA fast pull-down on GATE within 1μs. After an over-voltage condition, the MOSFET is held off until V IN once again remains below 5.7V for 130ms.OvercurrentThe overcurrent comparator protects the MOSFET from excessive current. It trips when the SENSE pin falls more than 50mV below IN for more than 10μs. When the overcur-rent comparator trips, GATE is pulled low quickly and the PWRGD pull-down releases. The L TC4361-2 automatically tries to apply power again after a 130ms start-up delay.Start-UpWhen V IN is less than the undervoltage lockout level of 2.1V , the GATE driver is held low and the PWRGD pull-down is high impedance. When V IN rises above 2.1V and ON is held low, a 130ms delay cycle starts. Any undervoltage or overvoltage event at IN (V IN < 2.1V or V IN > 5.7V) restarts the delay cycle. This delay allows the N-channel MOSFET to isolate the output from any input transients that occur at start-up. When the delay cycle completes, GATE starts its slow ramp-up.GATE ControlAn internal charge pump enhances the external N-channel MOSFET with 6V from GATE to OUT . This allows the use of logic-level N-channel MOSFETs. An internal 6V clamp between GATE and OUT protects the MOSFET gate.APPLICATIONS INFORMATIONThe L TC4361-1 has an internal latch that maintains this off state until it is reset. To reset this latch, cycle IN be-low 2.1V (V IN(UVL)) or ON above 1.5V (V ON(TH)) for more than 500μs. After reset, the L TC4361-1 goes through the start-up cycle.In applications not requiring the overcurrent protection, tie the SENSE pin to the IN pin. To implement an overcurrent threshold I TRIP , choose R SENSE using the formula:R SENSE=ΔV OC I TRIPAfter choosing the R SENSE, keep in mind that:I TRIP(MAX)=ΔV OC(MAX) R SENSE(MIN)I TRIP(MIN)=ΔV OC(MIN)R SENSE(MAX)PWRGD OutputPWRGD is an active low output with a MOSFET pull-downto ground and a 500k resistive pull-up to OUT. The PWRGDpin pull-down releases during the low current sleep mode(invoked by ON high), UVLO, overvoltage or overcurrentand the subsequent 130ms start-up delay. After the start-up delay, GATE starts its slow ramp-up and control of thePWRGD pull-down passes on to the GATE high comparator.V GATE > V GATE(TH) for more than 65ms asserts the PWRGDpull-down and V GATE < V GATE(TH) releases the pull-down.The PWRGD pull-down is capable of sinking up to 3mAof current allowing it to drive an optional LED. To inter-face PWRGD to another I/O rail, connect a resistor fromPWRGD to the I/O rail with a resistance low enough tooverride the internal 500k pull-up to OUT. Figure 2 detailsPWRGD behavior for a L TC4361-2 with 1k pull-up to 5Vat PWRGD.I436112 F02Figure 2. PWRGD Behavior9436112fA PPLICATIONS INFORMATIONON InputON is a CMOS compatible, active low enable input. It has a default 5μA pull-down to ground. Connect this pin to ground or leave open to enable normal device operation. If it is driven high while the external MOSFET is turned on, GATE is pulled low with a weak pull-down current (40μA) to turn off the external MOSF ET gradually, minimizing input voltage transients. The L TC4361 then goes into a low cur-rent sleep mode, drawing only 1.5μA at IN. When ON goes back low, the part restarts with a 130ms delay cycle. GATEP ControlGATEP has a 2M resistive pull-down to ground and a 5.8V Zener clamp in series with a 200k resistor to IN. It con-trols the gate of an optional external P-channel MOSFET to provide negative voltage protection. The 2M resistive pull-down turns on the MOSF ET once V IN – V GATEP is more than the MOSFET gate threshold voltage. The IN to GATEP Zener protects the MOSFET from gate overvoltage by clamping its V GS to 5.8V when V IN goes high. MOSFET Confi gurations and SelectionThe L TC4361 can be used with various external MOSFET confi gurations (see Figure 3). The simplest confi guration is a single N-channel MOSFET. It has the lowest R DS(ON) and voltage drop and is thus the most power effi cient solution. When GATE is pulled to ground, the N-channel MOSFET can isolate OUT from a positive voltage at IN up to the BV DSS of the N-channel MOSFET. However, reverse current can still fl ow from OUT to IN via the parasitic body diode of the N-channel MOSFET.F or near zero reverse-leakage current protection when GATE is pulled to ground, back-to-back N-channel MOSF ETs can be used. Adding an additional P-channel MOSF ET controlled by GATEP provides negative input voltage protection down to the BV DSS of the P-channel MOSFET. Another confi guration consists of a P-channel MOSFET controlled by GATEP and a N-channel MOSFET controlled by GATE. This provides protection against overvoltage and negative voltage but not reverse current.Figure 3.

The inductor L IN represents the lumped equivalent inductance of the cable and the EMI fi lter found in some wall adaptors. R IN is the lumped equivalent resistance of the cable, adaptor output capacitor ESR and the connector contact resistance.L IN and R IN form an LC tank circuit with any capacitance at IN. If the wall adaptor is powered up fi rst, plugging the wall adaptor output to IN does the equivalent of applying a voltage step to this LC circuit. The resultant voltage overshoot at IN can rise to twice the DC output voltage of the wall adaptor as shown in Figure 4. Figure 5 shows the 20V adaptor output applied to the L TC4361. Due to the low capacitance at the IN pin, the plug-in transient has been brought down to a manageable level.12436112fAPPLICATIONS INFORMATIONAs the IN pin can withstand up to 80V , a high voltage N-channel MOSF ET can be used to protect the system against rugged abuse from high transient or DC voltages up to the BV DSS of the MOSFET . Figure 6 shows a 50V input plugged into the L TC4361 controlling a 60V rated MOSFET .Input transients also occur when the current through the cable inductance changes abruptly. This can happen when the L TC4361 turns off the N-channel MOSFET rapidly in an overvoltage or overcurrent event. Figure 7 shows an input transient after an overcurrent. The current in L IN will cause V IN to overshoot and avalanche the N-channel MOSFET to C OUT . Typically, IN will be clamped to a voltage of V OUT + 1.3 • (BV DSS of Si1470DH) = 45V . This is well below the 85V absolute maximum voltage rating of the L TC4361.The single, nonrepetitive, pulse of energy (E AS ) absorbed by the MOSFET during this avalanche breakdown with a peak current I AS is approximated by the formula: E AS = 0.5 • L IN • I AS 2F or L IN = 0.7μH and I AS = 4A, then E AS = 5.6μJ. This is within the I AS and E AS capabilities of most MOSFET’s including the Si1470DH. So in most instances, the L TC4361 can ride through such transients without a bypass capacitor , transient voltage suppressor or other external components at IN. Note that if an IN bypass capacitor is used, the V IN transients will overshoot less but last longer . If V IN dips below V IN(UVL) for more than 10μs, the internal latch-off latch in the L TC4361-1 could be inadvertently reset.Figure 6. 50V Hot-Plug into the L TC4361Figure 7.

A 20V wall adaptor is mistakenly hot-plugged into the 5V device with the USB input already live. As shown in Figure 9, a large current can build up in L IN to charge up C OUT . When the N-channel MOSFET shuts off, the energy stored in L IN is dumped into C OUT , causing a large 40V input transient. The L TC4361 limits this to a 1V rise in the output voltage.If the ΔV OUT due to the discharge of the energy in L IN into C OUT is not acceptable or the avalanche capability of the MOSFET is exceeded, an additional external clamp such as the SMAJ24A can be placed between IN and GND. C OUT is the decoupling capacitor of the protected circuits and its value will largely be determined by their requirements. Using a larger C OUT will work with L IN to slow down the dV/dt at OUT , allowing time for the L TC4361 to shut off theMOSFET before V OUT overshoots to a dangerous voltage. A larger C OUT also helps to lower the ΔV OUT due to the discharge of the energy in L IN if the MOSFET BV DSS is used as an input yout ConsiderationsFigure 10 shows an example PCB layout for the L TC4361 (TS8 package) with a single N-channel MOSFET (SC70 package) and a 0603 size sense resistor . Keep the traces to the N-channel MOSFET wide and short. The PCB traces associated with the power path through the N-channel MOSFET should have low resistance. Use Kelvin connec-tions to R SENSE for an accurate overcurrent threshold.APPLICATIONS INFORMATION14436112fP ACKAGE DESCRIPTION DC Package8-Lead Plastic DFN (2mm × 2mm)(Reference L TC DWG # 05-08-1719 Rev A)1.

The block diagram of the board is shown below. It contains the ADF4360-6, a PC connector, plus SMA connectors for the power supplies, Reference Input, and RF outputs. It also contains a loop filter to complete the PLL. The eval board can be setup as necessary for the customer's PLL requirements. A cable is included with the board to connect to a PC printer port to allow software programmability.The package also contains windows software to allow easy programming of the synthesizer.RF OUT BINRF OUT A V VREV.PrC 08/03–2–Figure 1. Evaluation Board Silkscreen Figure 2. PC Cable DiagramHard ware DescriptionThe evaluation board comes with a cable for connecting to the printer port of a PC. The silk screen and cable diagram for the evaluation board are shown below. The board schematic is shown on pages 3 and 4.The board is powered from a single 9V battery.All components necessary for LO generation are catered for on-board. A 10MHz TCXO from Fox provides the necessary Reference Input. Otherwise an External Reference signal can be connected via SMA1.The PLL comprises the ADF4360-6 and a passive loop filter. The VCO outputs are available at RF OUT A through a standard SMA connector, plus the complementary VCO output is available from RF OUT B complementary connector.If the user wishes they may use their own power supplies and reference input, they can use the SMA connectors as shown on the silkscreen and block diagram. Control of the Chip Enable pin can be achieved by inserting J7, and removing R12. The on board filter is a Third Order,Passive Low Pass Filter. This contains three capacitors,(C13, C14 & C15), plus two resistors (R10 & R11). To save Board space, The footprint for R10 is located on the underside of the board. For design of the loop filter, It is designed for a centre frequency of 1.15GHz, and a channel spacing of 200kHz. The charge pump current setting is chosen to be 2.5mA. It's bandwidth is 10kHz.To design a filter for different setups, Please use ADIsimPLL.ADI SimPLLA copy of ADIsimPLL is also included on the eval kit CD. This software package designs, simulates and analyses the entire frequency domain and time domain response. You can use it to design an appropriate filter for the PLL. Various passive and active filter architectures are allowed.RF OUTPUT STAGESThe output RF stages can be customised to suit therequirements of the end-user. A tuned load, consisting of a 51nH shunt Inductor for each output (L5 & L6) isconnected to to Vvco. A series 2.7pF coupling capacitor (C17 & C19) is included plus a series 7.5nH Inductor (L3& L4) before the RF output to the SMA connector. This can be changed to optimise tuning to the desired fundamental frequency.If in doubt, a 50Ohm resistor can replace the shunt Inductor, and a zero-ohm link can short out L3 & L4.ADF4360-x CABLE CONNECTIONSPC Printer PortIf the the version of version of ADIsimPLL that you are using is not configured for the ADF4360-6, then you can design the loop filter by selecting the ADF4106 as a synthesizer and inserting all other relevant parametersfrom the ADF4360-6 datasheet. Be careful to note that the charge pump current is half that of the ADF4106.Figure 3. Evaluation Board Circuit Diagram (Page 1)–3–REV.PrC 08/03Figure 4. Evaluation Board Circuit Diagram (Page 2)REV.PrC 08/03–4––5–REV.PrC 08/03Figure 5. Software Front PanelSoftware DescriptionThe software comes on a CD. If the user double clicks on “setup.exe”, then the install wizard installs the software.Follow the on-screen directions. The software will be installed in a default directory called “C:/Program Files/Analog Devices/ADF4360”. To run the software, simply double-click on “ADF4360.exe”. It should be noted that this is a beta-version of software for the ADF4360.Before the main software screen appears, the Device win-dow appears, which will ask the user to choose which de-vice is being evaluated. Choose the appropriate version of the ADF4360 and click OK. The Main Interface window will now appear. (See Figure 5).Programmable Software SettingsClick on RF VCO Output Frequency, and the Output Frequency window will appear.
