AMI Oxytrace (QED)Product Description

2. Product DescriptionThis manual describes the functions of the monitors AMI Oxytrace and AMI Oxytrace QED. Both monitors are mainly identical except that AMI Oxytrace QED includes a faraday verification. AMI Oxytrace cannot be upgraded with the faraday verification.

2.1 Description of the systemApplication AMI Oxytrace is used to measure low levels of oxygen in high-

purity water. Especially in power plant water cycles (e.g. feedwater), a very low level of oxygen is needed to prevent corrosion.

Measuringprinciple

Clark principle:The sensor consists of one noble metal electrode (e.g. platinum or gold), a reference electrode (mostly Ag/AgCl) and optionally a metal guard electrode.The Clark-type electrode is the most used frequently oxygen sensor for measuring oxygen dissolved in a liquid. The basic principle is that there is a cathode and an anode submersed in an electrolyte and a voltage is applied between the two parts. Oxygen enters the sensor through a permeable membrane by diffusion, and is reduced at the cathode, creating a measurable electrical current.O2 + 2 e- + 2 H2O --> H2O2 + 2 OH-

There is a linear correlation between the oxygen concentration and the electrical current. The guard electrode mounted circularly around the cathode is on the same voltage level but there is no current measurement. Oxygen which diffuses from the electrolyte to the cathode is consumed by the guard. As a consequence, residual oxygen in the electrolyte will no more disturb the measurement signal and the response time to low oxygen levels will be shorter.

Temperaturecompensa-

tion

The measuring signal depends on temperature, but is automatically compensated to 25°C. The sample temperature is determined continuously by a temperature sensor inside the oxygen electrode.

On-lineoperation

Swansensor Oxytrace G combined with QV-flow PMMA OTG flow cell: The sample enters the flow cell at the sample inlet, passes the flow regulating valve, the faraday electrode and fills the flow cell. The oxygen concentration will be determined. Exiting the flow cell,

8 A-96.250.531 / 081128


the sample drives the rotor of the flowmeter (for flow monitoring) and the sample leaves the flow cell through the pressure-free outlet.

FaradayVerification

When a direct current is passed through water by means of two electrodes, electrolysis of the liquid takes place, according to the laws of Michael Faraday. Water is converted to molecular oxygen and hydrogen. Thus, by controlling the current, a fixed, known amount of oxygen, which is independent of temperature and pressure, may be generated. If the sample flow is known, an exact oxygen concentration increment can be generated at low levels. This increment is used to verify the flawless operation of the whole system. Thereby the response characteristics (incremental change and response time) of the sensor are taken into account. Sensor failures (loss of electrolyte etc.) can be detected very easily as shown in the plot below:.

Unusual sensor performance is recognized immediately and gives also a maintenance indication to the operator/user. The faraday verification is therefore an excellent QA/QC tool.

A-96.250.531 / 081128 23


4.2 MountingFor ease of operation, mount the instrument in a way that the display is on eye level. For the panel size, see Dimensions, p. 14

4.3 Connecting sample and wasteSample inlet:Connect the 1/4” stainless steel tube to the sample line following the instructions of Swagelok fittings:Insert the tubing into the Swagelok fitting. Make sure that the tubing rests firmly on the shoulder of the fitting and that the nut is finger-tight.While holding the fitting body steady with a backup wrench, tighten the nut 1 1/4 turns.

Waste:QV-Flow: Connect the 1/2” tube to the waste nozzle and place it into the atmospheric drain.B-flow: Swagelok connection 1/4”, identical to sample inlet.

Turn-on power

Switch on power.First, the analyzer performs a self test, displays the firmware ver-sion and then starts normal operation

Run-in PeriodCalibration

Leave the sensor at the air. The sensor has to run-in for at least 30 min, better 1 h. During this time it has to be at air with a dry and clean membrane and has to be connected to the powered instru-menty. Calibrate the sensor after this time (Air Calibration Proce-dure, p. 39) and mount it into the flow-cell afterwards.

Open Sample Flow

Open the flow regulating valve to allow sample flow into the flow cell and into the waste. Sample must always overflow into waste

AttentionHeavy inductive or direct controlled loads (solenoid valves, dosing pumps) must be switched by external power relays. In this case, use the AMI relay box which is available as an option.Small inductive loads (max 0.1 A) as for example the coil of a power relay can be switched directly. To avoid noise voltage in the AMI it is mandatory to connect an snubber circuit in parallel to the load (this procedure is not necessary if a AMI Relaybox is used)

AMI Oxytrace (QED)Maintenance

5. MaintenanceMaintenance frequency depends strongly on the water quality. The AMI Oxytrace is designed for determination of low level of dissolved oxygen in high purity water. It is NOT suitable for the measurement of dissolved oxygen in waste water.

5.1 Maintenance Schedule

*A change of membrane and electrolyte is recommended:if indicated in the maintenance list (remaining amount <10%)if the response of the sensor is slowif the sensor can not be calibrated any more and/or the instrument shows a corresponding error messageif the sensor signal is very unstable.

5.2 Stop Operation before MaintenanceStop sample flow.Shut off power of the instrument.To take the sensor out of the flow cell, turn the sensor mounting screw counter clockwise. Unscrew it completely. Open the sample valve slightly for a moment. This will loosen the tight

Weekly Check sample flow.Make manual measurement.If necessary, correct.

Monthly If necessary, perform an air calibration.

Half a year Clean Oxytrace G membrane with a soft tissue.Clean faraday electrode

Yearly If necessary, replace filling electrolyte.If the sensor is exposed to air frequently and during long time intervals, the electrolyte and membrane may have to be changed earlier (see below*).Clean flow cell and flow meter, if dirty.

Every 2nd year

Replace Oxytrace G electrode membrane by using a new, prefilled sensor cap.

seal of the sealing ring, and the electrode may be taken out of the flow cell easily. Do NOT pull the sensor with force!

5.3 Maintenance of Oxygen SensorFrom time to time it is necessary to exchange the electrolyte and membrane.

Warning: The filling solution is alkaline and caustic. It contains less than 1% of potassium hydroxide.

Do not ingest. Wear protective goggles and gloves during handling. Avoid contact with clothes.In case of accidental contact with the eyes, wash immediately with clear water and contact a physician. Show him the label of the bottle or this section of the manual.Short contact with skin is harmless, nevertheless wash with lots of water.

Switch of power.Screw off the sensor cap. Exhaust the remaining electrolyte.Refill the sensor cap with fresh electrolyte.There is a groove in the electrode thread, where excessive air and electrolyte can escape while mounting the sensor cap. Hold the sensor in upright position, sensor tip pointing downwards, with the groove on the upper side.Slowly fix the electrode head and the sensor cap to allow the excess electrolyte to escape without building up too much pressure inside the electrode. Fasten sensor cap tightly.Clean the electrode thoroughly and dry the sensing membrane with a soft tissue.Switch on power. Let the sensor run-in at air for at least 30 min, better 1 h. Afterwards perform an air calibration and install the sensor into the flow cell again.Reset the counter for remaining electrolyte (menu 3.2.5) by selecting New Filling - YES.

5.4 Cleaning of Flow Cell and SensorDepending on the water quality, the sensor and the flow cell will necessitate a cleaning.Before cleaning, stop operation as described in Stop Operation before Maintenance, p. 35. Afterwards:

Dismount the oxygen sensorClean the sensor with a soft tissue and rinse it with water afterwardsUse a soft brush to remove the dirt which sticks on the walls of the flow cell.Flush the flow cell with clean water. Remount the oxygen sensor and start sample flow.

A-96.250.531 / 081128 37


5.5 Maintenance of the Faraday electrodeTurn off the instrument and close sample valve.Disconnect Faraday electrode cable (A) from faraday control unit.Loose black screw (B) completely and pull out Faraday electrode (do not pull cable).Strip of washer (C) and o-ring seal (D).

Attention: Take care when disassembling the electrode. Do not bend nor force.

Unscrew electrode tip containing the hollow electrode (G).Clean the inner electrode (E) with a tissue, the hollow electrode with a pipe cleaner. The electrode surfaces should be shining metallic after cleaning. Use probably a polishing detergent or a small amount of toothpaste.Rinse well with water.Reassemble hollow electrode finger-tight and place into flow-through cell. Replace o-ring, washer and black screw, if necessary.Tighten screw (B) firmly.Connect electrode cable (see Sensor Connections, p. 34) and turn instrument on.Turn on sample flow. Check for air bubbles and set flow to roughly 8 l/h.

5.6 CalibrationAir

CalibrationProcedure

If the instrument is in operation, turn off the sample flow by closing the appropriate valve (sample inlet).Take the electrode out of the flow cell:

– Turn the fastening of the sensor counter clockwise. Unscrew it completely.

– Open the sample valve slightly for a moment.This will loosen the tight seal of the sealing ring, and the electrode may be taken out of the flow cell easily.Avoid pulling the electrode with force.

Dry the electrode's body and sensing membrane with a soft paper tissue. This is very important!Place the electrode slightly tilted into the flow cell, so that the sensor cap of the electrode rests on the rim for the sealing ring.In the wet flow cell, the atmosphere will be saturated with water vapour. This atmosphere will produce the most accurate calibration results. The sensing part of the electrode must not be in direct contact with water!Choose menu 3 (maintenance), then calibration (point 3.1). Press Enter. Follow instructions on the screen.The calibration is now done automatically. As soon as the reading is stable, the microprocessor will store the calibration data in the memory.The required time for a calibration depends mainly on the difference between temperature and oxygen content in the sample and in the air. It can take 15 - 20 minutes. This is also the case, if the electrolyte was exchanged. The end of the calibration is indicated on the display. Push Enter to confirm the calibration.Insert the electrode back into the flow cell, push down completely. Tighten the sensor fastening.Turn the sample flow on and off until all air bubbles are flushed out.

A-96.250.531 / 081128 39


Hold aftercalibration

During calibration, control is interrupted. The signal outputs are frozen if hold after calibration has been programmed (menu 4.3.4.2). Otherwise the outputs track the measuring value. Hold after calibration is indicated by Hold in the display.For additional explanations see Error Codes, p. 43

Calibrationverification

The calibration value should be verified monthly. Leave the sensor with clean and dry membrane at air. Set the display to % saturation and check the calibration value. The air pressure is automatically acquired during calibration. Therefore the influence of altitude and pressure variations because of the weather are eliminated.

5.7 Zero-VerificationSWANSENSOR OXYTRACE G for the measurement of low oxygen content (< 1 ppb).

Prepare a 5%-sodium sulfite solution with demineralized water.If necessary, install the electrode according to the description in the manual (Maintenance of Oxygen Sensor, p. 36), i. e. place a measuring membrane into the head screw cap of the electrode and fill it with electrolyte.Calibrate according to the manual (Air Calibration Procedure, p. 39).Put the electrode into the sodium sulfite solution afterwards. Assure that there are no air bubbles in front of the sensor.The measured value should now be < 1 ppb.Depending on the state of the electrode this process can take several hours. In case of an electrode-refill, this can take days until the measured value is lower than 1 ppb.

AMI Oxytrace (QED)Profibus (option)

B. Profibus (option)

B.1 IntroductionThe AMI family of transmitters provides a common base for a number of analytical instruments with application specific sensor interfaces. Each instrument has a basic structure with identical functionality.

AMI instruments can (optionally) be equipped with a PROFIBUS DP-V1 interface. The interface supports the PROFIBUS-PA Profile 3.0. This part of the manual describes the functionality of the interface and the integration of the AMI family of transmitters into an automation system.

Hardware Wiring, bus terminals and connectors are not part of this manual. It should, however, be noted that the observation of the corresponding standards is of paramount importance to proper operation. Setting the transmission rate to reasonable values will help avoid communication errors.

GSD File forAMI Oxytrace

The PROFIBUS system requires a description of the device parameters, e. g. output data, input data, data format, data volume and supported transmission rate, so that it can integrate the field devices into the bus system. These data are contained in a Device Master File (GSD file) which is placed at the disposal of the PROFIBUS master while communication system is being commissioned.

Device bitmaps can also be integrated. These appear as icons in the network tree.The manufacturer-specific GSD file SW17E1.gsd is available for download from http://www.swan.ch

The output data is transferred to AMI Oxytrace in the following structure:

B.3 Customizing the Cyclic Data TelegramYou can customize the cyclic telegram to better meet the requirements of a process. The tables above represent the maximum contents of the cyclic data telegram. If you do not want to use all the cyclic data of AMI Oxytrace, you can use the device configuration (Chk_Cfg) to eliminate individual data blocks from the cyclic telegram via the PLC software. Shortening the telegram improves the data throughput rate of a PROFIBUS system. You should only keep those blocks active which you process further in the system. You can do this by means of a "negative" selection in the configuration tool. To achieve the correct structure of the cyclic data telegram, the PROFIBUS master must send the identification FREE_PLACE (00h) for the non-active blocks.

B.5 Configuration

B.5.1 Device Master Files (GSD)The device is ready for system integration once commissioning has been effected via the local display or the Class 2 master. The PROFIBUS system requires a description of the device parameters, e.g. output data, input data, data format, data volume and supported transmission rate, so that it can integrate the field devices into the bus system. These data are contained in a Device Master File (GSD file) which is placed at the disposal of the PROFIBUS master while the communication system is being commissioned. Device bitmaps can also be integrated. These appear as icons in the network tree. The Profile 3.0 Device Master File (GSD) allows field devices from various manufacturers to be exchanged without having to reconfigure.

B.5.2 GSD File TypesPrior to configuration, decide which GSD you want to use to operate the system.You can change the setting by means of a Class 2 master (under Physical Block-Parameter Ident_Number_Selector).

The following two Device Master Files with different functionalities are available:

Manufacturer-specific GSD with Profile 3.0 functionality (default setting):

This GSD guarantees the unlimited functionality of the field device. Device-specific process parameters and functions are therefore available.

Profile GSD's: If a system is configured with profile GSD's, it is possible to exchange devices that are supplied by various manufacturers. It is, however, essential that the cyclic process values follow the same sequence. The transmitter supports the profiles Analyzer and Multivariable (IEC 61158-2). These GSD's comprise Analog Input blocks (AI).

A-96.250.531 / 081128 55


GSD files for AMI Oxytrace:

Working with GSD files The GSDs must be integrated into the automation system. Depending on the software that is being used, the GSD files can be copied to the program-specific directory or can be read into the database using the import function within the configuration software.

B.6 Acyclic Data CommunicationThe AMI Series of analytical instruments is available for a wide range of parameters. Instrument configuration depends on connected sensors and application. Therefore, configuration must be performed by trained personnel with a background in analytical methods.

It should be noted that there is a clear distinction between instruments that are configured and calibrated in an application (flow, level, pressure) and instruments that are calibrated with a known standard (pH, chlorine). AMI instruments are of the second type.

To ensure reliability and consistency of the measurement, remote configuration has not been enabled at this time.

AMI Oxytrace (QED)Modbus (option)

C. Modbus (option)

C.1 IntroductionThe AMI Oxytrace is an electronic transmitter / controller for the measurement of dissolved oxygen in high purity water. It can be operated as an intelligent slave device on the Modbus/JBUS using twisted pair RS485 lines.

Modbus/Jbus The Modbus / Jbus Protocol communicates using a master-slave technique, in which only one device (the master) can initiate transactions (queries). The other devices (the slaves) respond by supplying the requested data to the master, or by taking the action requested in the query. Typical master devices include host processors, PLCs etc. Typical slaves can be PLCs or intelligent transmitter/controller like the AMI family of the instruments.

The Query The function code in the query tells the addressed slave device what kind of action to perform. The data bytes contain any additional information the slave will need to function. For example, function code 03 will query the slave to read holding registers and respond with their contents. The data field must contain the information telling the slave which register to start at and how many registers to read.

The Re-sponse

If the slave makes a normal response, the function code in the response is an echo of the function code in the query. The data bytes contain the data collected by the slave.

SerialTransmission

modes

Modbus supports two transmission modes: ASCII or RTU. The AMI Instruments support Modbus RTU (Remote Terminal Unit) mode only.

RTU Mode In RTU mode, each 8-bit byte in a message contains two 4-bit hexadecimal characters. The main advantage of this mode is that its greater character density allows better data throughput than ASCII for the same baud rate. Each message must be transmitted in a continuous stream. Users select the desired serial port communication parameters (baud rate, parity mode, etc). The serial parameters must be the same for all devices on a Modbus network.

Coding SystemEight bit binary1 start bit8 data bits, least significant bit sent first1 bit for even / odd parity, no bit for no parity1 stop bit if parity is used, 2 bits if no parityCyclic Redundancy Check (CRC)RTU framing: messages start with a silent interval of at least 3 ½ character times. A similar interval of at least 3 ½ character times marks the end of the message.

A typical message frame is shown below

C.2. Data and Control FunctionsData address Data Addresses in Modbus Messages

All data addresses in Modbus Messages are referenced to zero. The first occurrence of a data item is addressed as item number zero. For example:

Holding Register 40001 is addressed as register 0000 in the data address field of the message. The function code field already specifies a holding register operation. Therefore the 4x reference is implicit.

Functioncodes

Modbus Function CodesThe list below shows the function codes supported by the AMI Instruments. Codes are listed in decimal. Function codes not supported return an exception response 02 to the master.Table 1: Modbus function codes

Data re-presentation

Data representationThe process- and parameter data of the AMI Instruments are represented by float (IEEE 754), signed- or unsigned integer values. Depending on the range of the value, float, integer8, unsigned8, integer16, unsigned16, integer32 or unsigned32 representation is used.

Discrete InputsAlarm &Status bits are packed as one input per bit of the data field.

Definition: big-endian and little-endianBig-endian and little-endian are terms that describe the order in which a sequence of bytes are stored in computer memory. Big-endian is an order in which the "big end" (most significant value in the sequence) is stored first (at the lowest storage address). Little-endian is an order in which the "little end" (least significant value in the sequence) is stored first. For example, in a big-endian computer, the two bytes required for the hexadecimal number 4F52 would be stored as 4F52 in storage. In a little-endian system, it would be stored as 524F.Attention: big-endian format is used !!!

As control output:Signal outputs can be used for driving control units. We distinguish different kinds of controls:

P-controller: The controller action is proportional to the deviation from the setpoint. The controller is characterized by the P-Band. In the steady-state, the setpoint will never be reached. The deviation is called steady-state error.Parameters: setpoint, P-BandPI-controller: The combination of a P-controller with an I-controller will minimize the steady-state error. If the reset time is set to zero, the I-controller is switched off.Parameters: setpoint, P-Band, reset timePD-controller: The combination of a P-controller with a D-controller will minimize the response time to a fast change of the process value. If the derivative time is set to zero, the D-controller is switched off.Parameters: setpoint, P-Band, derivative time.PID-controller: The combination of a P-, an I- and a D-controller allows a proper control of the process.Parameters: setpoint, P-Band, reset time, derivative time

Ziegler-Nichols method for the optimization of a PID controller:

The point of intersection of the tangent with the respective axis will result in the parameters a and L .Consult the manual of the control unit for connecting and programming details. Choose control upwards or downwards.
