I-E67-84-2B March 25, 2002 viii
SPECIFICWARNINGS
Use this equipment only in those classes of hazardous locationslisted on the nameplate. Uses in other hazardous locations canlead to unsafe conditions that can injure personnel and damageequipment.
Allow only qualified personnel (refer to INTENDED USER in SECTION1 - INTRODUCTION) to commission, operate, service or repair thisequipment. Failure to follow the procedures described in thisinstruction or the instructions provided with related equipmentcan result in an unsafe condition that can injure personnel anddamage equipment.
Consider the material compatibility between cleaning fluids andprocess liquids. Incompatible fluids can react with each othercausing injury to personnel and equipment damage.
Use solvents only in well ventilated areas. Avoid prolonged orrepeated breathing of vapors or contact with skin. Solvents cancause nausea, dizziness, and skin irritation. In some cases,overexposure to solvents has caused nerve and brain damage.Solvents are flammable - do not use near extreme heat or openflame.
Do not substitute components that compromise the certificationslisted on the nameplate. Invalidating the certifications can leadto unsafe conditions that can injure personnel and damageequipment.
Do not disconnect equipment unless power has been switched off atthe source or the area is known to be nonhazardous. Disconnectingequipment in a hazardous location with source power on can producean ignition-capable arc that can injure personnel and damageequipment.
Remove power from the unit and allow at least one minute for theunit to discharge before performing these procedures. Failure todo so constitutes an electrical shock hazard that can injurepersonnel and damage equipment.
Disconnect the AC line cord or power lines from the operatingbranch circuit coming from the source before attempting electricalconnections. Instruments powered by AC line voltage constitute apotential for personnel injury due to electric shock.
Keep the enclosure and covers in place after completing the wiringprocedures and during normal operation. Do not disconnect orconnect wiring or remove or insert printed circuit boards unlesspower has been removed and the flammable atmosphere is known NOTto be present. These procedures are not considered normaloperation. The enclosure prevents operator access to energizedcomponents and to those that can cause ignition capable arcs.Failure to follow this warning can lead to unsafe conditions thatcan injure personnel and damage equipment.
All error conditions are considered catastrophic. When such anerror has been reported, the analyzer should be replaced with aknown-good analyzer. The non-functional analyzer should bereturned to the factory for repair. Contact the factory for aReturn Materials Authorization (RMA) number.

SECTION 2 - ANALYZER FUNCTIONALITY ANDOPERATOR INTERFACE CONTROLS
INTRODUCTION
The beginning of this section contains anoverview of the TB84EC Four-ElectrodeConductivity Advantage Series analyzerfunctionality and important information forconfiguration personnel. The latter part ofthis section discusses the operator interfacecontrols. It includes descriptions of theanalyzer modes and faceplate controls.
ANALYZER OVERVIEW
The TB84EC Advantage Series analyzer providestwo analog output signals that can beconfigured to the solution conductivity asmeasured by the analyzer and sensor. Inaddition to the two analog outputs, any of thethree integral relay outputs can be configuredas a high or low setpoint controller, cycle-timer controller, diagnostic alarm, or cleanercontroller. In this manner, the TB84ECAdvantage Series analyzer provides a means bywhich to monitor and control the conductivityor concentration of a process fluid. This analyzer is equipped with internaldiagnostic capabilities allowing for thedetection of any potential problems with theelectronics and operation of firmware.Diagnostic capability also includes thedetection of sensor integrity such as ground-loop detection, dirty sensor detection,process variables out of range, and incorrectcalibration values.
USER INTERFACE
The user interface consists of a tactilekeypad having four Smart keys, one hidden key,and a custom LCD. The LCD has a three andone-half digit numeric region that displaysthe process variable, a six-digit alphanumericregion that displays secondary information andprogramming prompts, and several status-indicating and programming icons.
I-E67-84-2B March 25, 2002 2-2
Using a novel approach (patent-pending), eachof the four keys is located under a given setof icons. In each of the instrument modes andmode states, one icon over any given key willbe illuminated and will represent that key’sfunction. These Smart Key assignments willvary as the user enters into differentprogramming modes and states. In addition tothe Smart Key assignments, text stringslocated in the six character alphanumericfield (i.e., secondary display) are used asprogramming prompts. The end result is aninterface that provides a great deal offlexibility and functionality.
MODULAR ELECTRONIC ASSEMBLIES
The TB84EC Advantage Series analyzer consistsof three separate PCB assemblies thatconcentrate specific circuit functionalityonto each of the three boards. This modulardesign allows for the ability to change theinstrument from one of four types ofinstruments: pH/ORP/pION, four-electrodeconductivity, two-electrode conductivity, andtoroidal conductivity. In addition, analyzerrepairs can be quickly accomplished by simplyreplacing the non-functioning board with onethat is operational.
TEMPERATURE COMPENSATION
The process temperature can be monitored usingone of three types of RTD inputs: 3 kohmBalco, Pt100 (US385), and ABB’s Standard 4.75kohm network. The secondary display area canalso be set to display the temperature indegrees Celsius or Fahrenheit when the TB84ECAdvantage Series is in the Measure mode ofoperation.
Since temperature affects the activity anddisassociation of ions and hence theconductivity of the solution, severaltemperature compensation functions areavailable. Temperature compensation optionsfor conductivity and concentration includeManual (0.1N KCl based) and ten types ofAutomatic Compensation routines. See Section1, Introduction, for compensation types.
I-E67-84-2B March 25, 2002 2-3
ANALOG OUTPUTS
The TB84EC Advantage Series analyzer has twoanalog outputs. These outputs can be eitherdirect or reverse acting and can be software-configured for a range of zero to 20 milliampsor four to 20 milliamps. Both outputs areseparately scalable, isolated from the input,and isolated from one another.
The analog outputs provide process informationto recorders, data loggers, and controlsystems. The information transmitted canrepresent (i.e., be sourced to) theconductivity, concentration, or temperature ofthe solution and be ranged across any portionof the particular measurement range. SeeTable 1-3, Specification, for minimum andmaximum range values.
RELAY OUTPUTS
The TB84EC Advantage Series analyzer has threeForm C, SPDT relay outputs. The relays can beindependently programmed to perform variousfunctions as required by the application.
These functions include:
C Process control (Setpoint or Cycle Timer).C Diagnostic condition notification.C Cleaner control.
High or Low Set Point
High or low set point relays are configurablefor any value within the measurement range.Each set point relay output allows forseparate programmability of relay function(high or low), set point value, deadbandvalue, and delay.
The example shown in Figure 2-1 illustrates ahigh set point relay output of 10.00 mS/cmwith a deadband of 0.10 mS/cm. The relayactivates at 10.00 mS/cm and deactivates whenthe process drops below 9.90 mS/cm. Thesecond half of the figure shows the samesituation with a 1.0 minute delay before thehigh set point relay activates. Set point

functions are programmable as high or lowacting. Setpoint, deadband, and delay valueare all tunable parameters available in theSetpoint/Tune Mode of Operation.
Figure 2-1. High Set Point and Time Delay Example.
High or Low Cycle Timer
High or low cycle timer relays areconfigurable for any value within themeasurement range. A cycle timer relay outputallows for separate programmability of relayfunction (high or low), set point value, cycletime, and on time.
The example shown in Figure 2-2 illustrates acycle timer that will be active when theprocess variable exceeds the high set pointvalue of 10.00 mS/cm. Once active, the relayoutput energizes for the configured on time.As long as the process continues to exceed theset point value, the timer will reset itselfat the end of the duty cycle (i.e., cycletime). The set point, cycle time, and on timeare all tunable parameters available in theSetpoint/Tune Mode of Operation.
FIGURE 2.2. Cycle Timer High Set Point Example.
I-E67-84-2B March 25, 2002 2-5
Cleaner
Automatic sensor cleaning can be accomplishedusing one of the three relay outputs. At aprescribed time interval (i.e., cycle time), acleaner relay output will energize and thusenable a cleaning device. The cleaner relaywill remain energized for a configuredcleaning period (i.e., on time). Since manycleaning devices use cleaning solutions thatcan affect the process measurement, the analogand non-cleaner relay outputs can be heldduring the cleaning period. If needed, non-cleaner relay outputs can be completelydisabled (i.e., de-energized) instead of held.Thus, an operator does not need to beconcerned with the possibility of a non-cleaner relay being held in an incorrect statefor an undesirable length of time.
In addition to a cleaning period, a recoveryperiod can be programmed to extent anyconfigured hold and/or disabling conditionsbeyond the clean period. This feature allowscleaning fluids to dissipate or sensorconditions to stabilize before returning tothe normal mode of operation.
The set point, cycle time, and on time are alltunable parameters available in theSetpoint/Tune Mode of Operation.
DAMPING
Damping can be adjusted from 0 to 99.9seconds. This feature is useful in noisyprocess environments to help stabilize thedisplayed process variable and output currentfrom excess bounce. Damping can be applied tothe displayed and/or analog output values.
Damping simulates a capacitive type lag wherereaction to any signal change is slowedaccording to an entered time constant. Forexample, a step change will reachapproximately 63 percent of its final value infive seconds for five seconds of damping.
I-E67-84-2B March 25, 2002 2-6
DIAGNOSTICS
Diagnostics are provided for both the analyzerand sensor. Diagnostic detection of a seriouscondition that prevents the instrument fromproperly functioning enables preset Safe Modestates. These Safe Mode states are configuredby the user and forces the outputs either highand/or low.
For problems that occur that do not render theinstrument in a non-functioning state, theuser has the option of linking theseconditions to a Diagnostic Spike that issuperimposed onto Analog Output One and/or toa one or more relay outputs.
If the Diagnostic Spike is enabled, AnalogOutput One will modulate for one out of everysix seconds. The magnitude of the modulationcan be set from 0 to 100% of the analyzer’smaximum output (i.e., 0 to 16 or 20 mA).
Diagnostic conditions cause the FAULT andFAULT INFO icons on the display to beenergized. Interrogation of each faultcondition is available with a singlekeystroke.
Analyzer
Four critical errors in operation aremonitored and linked to the Safe Mode feature.These conditions include inoperable orincorrect input circuit, bad RAM, and damagedEE memory.
Sensor
The analyzer continually performs diagnosticchecks on sensor integrity. Inconsistenciesin sensor performance are notified by theFAULT and FAULT INFO icons as well as theSpike Output and/or Diagnostic Relay(s) ifconfigured.
Sensor faults include ground-loop detection,dirty sensor detection, high and low PV, highand low temperature, and many more. SeeSection 13, Diagnostics, for more details.
I-E67-84-2B March 25, 2002 2-7
Spike Output
Remote problem condition notification can beinitiated by the TB84EC Advantage Seriesanalyzer using the SPIKE State in theConfigure Mode. The Spike Output optionallows users to program a 0 to 100% (i.e., 0to 16 mA for 4 to 20 mA configurations or 0 to20 mA for 0 to 20 mA configurations) pulsethat will be impressed on Analog Output Onefor one second out of a six second repeatingcycle should a problem condition be detected.Should the actual output of the analyzer bebelow mid-scale, the pulse will add current;if above mid-scale, it will subtract current.

SECTION 3 - INSTALLATION
INTRODUCTION
This section of the manual will aide the userin all levels of the installation process.The intention is to provide simple proceduresfor placing the TB84EC Advantage Seriesanalyzer into service.
SPECIAL HANDLING
Besides the normal precautions for storage andhandling of electronic equipment, the analyzerhas special static sensitive device (SSD)handling requirements. This equipmentcontains semiconductors subject to damage bydischarge of static electricity; therefore,avoid direct contact with terminal blockconductors and electronic components on thecircuit board.
To minimize the chances of damage by staticelectricity, follow these techniques duringwiring, service, troubleshooting, and repair.
1. Remove assemblies containingsemiconductors from their protectivecontainers only:
a. When at a designated static-free workstation.
b. After firm contact with an antistaticmat and/or gripped by a grounded individual.
2. Personnel handling assemblies withsemiconductors must be neutralized to astatic-free work station by a grounding wriststrap connected to the station or to a goodground point at the field site.
3. Do not allow clothing to make contactwith semiconductors. Most clothing generatesstatic electricity.
4. Do not touch connectors, circuit traces,and components.
I-E67-84-2B March 25, 2002 3-2
5. Avoid partial connection ofsemiconductors. Semiconductors can be damagedby floating leads. Always install electronicassemblies with power removed. Do not cutleads or lift circuit paths whentroubleshooting.
6. Ground all test equipment.
7. Avoid static charges during maintenance.Make sure the circuit board is thoroughlyclean around its leads but do not rub or cleanwith an insulating cloth.
NOTE: An antistatic field service kit, ABB part number1948385_1, is available for personnel working ondevices containing static sensitive components. Thekit contains a static dissipative work surface (mat),a ground cord assembly, wrist bands, and alligatorclip.
UNPACKING AND INSPECTION
Examine the equipment upon receipt forpossible damage in transit. File a damageclaim with the responsible transportationcompany, if necessary. Notify the nearest ABBsales office.
Carefully inspect the packing material beforediscarding it to make certain that allmounting equipment and any specialinstructions or paperwork have been removed.Careful handling and installation will ensuresatisfactory performance of the unit.
Use the original packing material andcontainer for storage. Select a storageenvironment free of corrosive vapors andextreme temperature and humidity. Storagetemperature must not exceed -40 degrees to +70degrees Celsius (-40 degrees to +158 degreesFahrenheit).
Remove the protective film from the analyzerlens after the analyzer has been placed in itsfinal installed location.
I-E67-84-2B March 25, 2002 3-3
LOCATION CONSIDERATIONS
When mounting the unit, leave ample clearancefor removal of the front bezel and rear cover.Signal wiring should not run in conduit oropen trays where power wiring or heavyelectrical equipment could contact orinterfere with the signal wiring.

WIRING CONNECTIONS AND CABLING
CAUTION To prevent possible signal degradation,separate metal conduit runs are recommendedfor the sensor, signal, and power wiring.
Under ideal conditions, the use of conduit andshielded wire may not be required. However,to avoid noise problems, power, signal, andoutput wiring should be enclosed in separateconduit. Just prior to entering the housing,rigid conduit should be terminated and a shortlength of flexible conduit should be installedto reduce any stress to the housing.
Note: To maintain a NEMA 4X/IP65 rating, use approvedconduit connections or cord grips that have the same typeof ratings.
Power and signal wiring must bear a suitablevoltage rating, have a maximum temperaturerating of 75 C (167 F), and must be ino o
accordance with all NEC requirements orequivalent for the installation site. Useeither a standard three-prong groundedflexible CSA certified line cord or equivalentfor power supply connection or hard wiredirectly to the AC supply. If hard wiring theAC power supply, use stranded, 14 AWG copperconductor wire.
Signal wiring should not be run in the sameconduit or open trays where power wiring forhigh amperage electrical equipment exists.Ensure the final installation of signal andpower wiring prevents physical and/orelectrical interfere.
Note: Use weatherproof connections for all wiring ports.Heyco RLTF ½" and LTF 9 cable grips are available throughABB. See Section 17, Support Services.
The TB84EC Advantage Series analyzer acceptswire sizes 12 to 24 AWG. Signal wiring shouldalways be twisted, shielded pairs to ensurethe best performance. Pin-style terminals arerecommended for all connections and availableas kits from the factory. See section 17,Support Services, for more information.
I-E67-84-2B March 25, 2002 3-10
Power Wiring
WARNING Disconnect the AC line cord or power linesfrom the operating branch circuit coming fromthe source before attempting electricalconnections. Instruments powered by AC linevoltage constitute a potential for personnelinjury due to electric shock.
WARNING Keep the enclosure and covers in place aftercompleting the wiring procedures and duringnormal operation. Do not disconnect orconnect wiring or remove or insert printedcircuit boards unless power has been removedand the flammable atmosphere is known NOT tobe present. These procedures are notconsidered normal operation. The enclosureprevents operator access to energizedcomponents and to those that can causeignition capable arcs. Failure to followthis warning can lead to unsafe conditionsthat can injure personnel and damageequipment.
The TB84EC Advantage Series analyzer does notrequire pre-setting a jumper to acceptdifferent line-power voltages. Powerconnections are located in the back of theinstrument housing. The terminal block labelidentifies all line power, output signal, andsensor connections.
Notes:1. ABB recommends installing a power line switch forsafety purposes and for providing power-up and power-downconvenience when servicing the analyzer.
2. Do not power the system from a transformer that alsopowers large motor loads (over five horsepower) or anyother type of equipment that generates line voltagesurges, sags and excessive noise.
Using Figure 3-7 as a reference, make linepower connections as follows:
1) Strip wire insulation back approximately0.250" (seven millimeters) to ensure the barewire will make good contact with the InsulatedPin Lug terminals and will not be exposedbeyond the pin insulator.
I-E67-84-2B March 25, 2002 3-11
2) Crimp Pin Lug terminals to wire usingPanaduit CT 570 or equivalent.
3) Connect the specified line voltage toTB1-1 (Line - L1), the neutral to TB1-2(Neutral - L2), and the ground to terminalTB1-3 (Chassis Ground).
Analog Output Signal Wiring
The terminal block label identifies the analogoutput connections. Terminal polarity isshown and must be observed to ensure properoperation. The maximum load resistance forthe analog outputs is specified in Table 1-3,Specifications. The maximum load resistancemust include all devices and wiring within theanalog output current loop. See Figure 3-7for a wiring diagram.
Using Figure 3-7 as a reference, make analogoutput connections as follows:
1) Strip wire insulation back approximately0.250" (seven millimeters) to ensure the barewire will make good contact with the InsulatedPin Lug terminals and will not be exposedbeyond the pin insulator.
2) Crimp Pin Lug terminals to the wire usingPanaduit CT 570 or equivalent.
3) Connect the wiring to the appropriateanalog output terminals.
Relay Output Signal Wiring
The relay outputs are shipped from the factoryin the default state of Normally Open. Thatis, the relay contacts will be open when therelay is not energized. To change the normalstate of any of the three relay outputs,switches on the power supply PCB assembly mustbe moved to different positions.

GROUNDING
The customer and/or wiring contractor isresponsible to ensure the analyzer, associatedcontrol or test equipment, and all exposedconductive materials are properly grounded.Grounding procedures should be in accordancewith local regulations such as the NationalElectrical Code (NEC), Canadian ElectricalCode (CEC), or equivalent. Equipmentinstallations must not pose a hazard,including under fault conditions, to operationand service personnel.
Signal wiring should be grounded at any onepoint in the signal loop or may be ungrounded(floating) if electrical noise is minimal.
I-E67-84-2B March 25, 2002 3-15
The analyzer enclosure must be grounded to anearth ground having less than 0.2 ohms ofresistance. Internal and external earthground terminals are provided and shown inFigure 3-7.
Notes:
1. Because of the prevailing differences in soilconditions and in acceptable grounding practicesthroughout the world, the scope of this productinstruction is not intended to be used to describegrounding electrode systems. The customer is responsibleto ensure a grounding electrode system is acceptable tothe local building and wiring codes.
2. Using the structural metal frame of a building as therequired equipment grounding conductor for the analyzer isnot advised.

SECTION 4 - OPERATING PROCEDURES
INTRODUCTION
The TB84EC Advantage Series analyzer has sevenmain operating modes: Measure, Calibrate,Output/Hold, Configure, Security, secondaryDisplay, and Setpoint/Tune. Within each mode,several programming states containingfunctions specific to the related mode areavailable.
The TB84EC Advantage Series analyzer isequipped with a built-in user interfacethrough which all analyzer functions areprogrammed or monitored. In order to maximizethe viewing area and minimize the space neededfor the keypad, the interface is based on acustom LCD that contains a group of two ormore icons for each button on the four buttonkeypad. The icon description representsfunction of particular key.
Two display regions in the custom LCD handlethe majority of instrument functions. Theseregions include a primary display area for theprocess variable (e.g., pH) and a secondarydisplay area for programming text prompts orauxiliary information.
In addition to the user-friendly interface,the TB84EC Advantage Series analyzer isequipped with a group of icons that alerts theuser to an existing FAULT condition,diagnostic SPIKE output, output HOLDcondition, or activated RELAY. These iconsare located at the top of the LCD and are onlyenergized when the specified condition isdetected. FAULT conditions are shown in thesecondary display when the instrument is inthe Measure Mode of Operation and the FAULTINFO key has been pressed.

Liquid Crystal Display (LCD)
The LCD contains nine regions that provide theuser with information on the process variable,engineering units, mode of operation, anoutput hold, fault, relay activation,secondary variable, and key functionassignments. Figure 4-1 shows a fullyenergized LCD, Smart Keys, and mode text.
Figure 4-1. Fully Energized Display AndSupporting Information.
The top set of icons informs the user ofabnormal operating conditions such as anoutput HOLD, FAULT, diagnostic SPIKE output,or RELAY activation. These icons are onlyenergized when such a condition is detectedand are active in all modes of operation.
For the mode of operation indicators (i.e.,right arrows positioned next to the modetext), only one indicator will be lit and willindicate the current mode of operation of theanalyzer. As a user moves from one mode tothe next, the appropriate indicator willenergize. The mode of operation indicatorsare active in all modes of operation.
I-E67-84-2B March 25, 2002 4-3
The process variable is displayed in the threeand one-half digit, seven segment region.This display region is supported by theengineering unit region. These regions areactive in all modes of operation; however, insome programming states, the process variableregion will be used for data entry and theengineering unit region will reflect the dataunit.
The secondary variable is displayed in thesix-character, fourteen segment region. Thisdisplay region is used for displayingsecondary information and fault information inthe Measure Mode of Operation and programmingprompt in all other modes of operation. Dueto the limited number of characters for thisdisplay region, much of the prompting takesthe form of text abbreviations (see Appendix Bfor a list of abbreviations.) This region isactive in all modes of operation.
The Smart Key assignments are grouped intofour sets of icons, each group directlypositioned above one of the four keys. Theseicons are textual representations of thefunction for the associated key. Only oneassignment will be energized per Smart Key atany given time.
Multi-Function Smart Keys
A five-button, tactile keypad is located onthe front panel of the instrument. Four ofthe buttons are embossed to easily show theirlocation. A fifth, hidden button located top,center of the keypad has been included toprovide access to functions that areinfrequently used.
The four embossed keys are called Smart Keyssince their functions are dependent on themode and/or state of the instrument. Sincethese four keys do not have a preassignedfunction, multiple functions can be assignedto a single key at different time byenergizing the appropriate icon. Using thisSmart Key method, a smaller number of keys canbe used without complicating instrumentfunctionality. If a Smart Key does not have

I-E67-84-2B March 25, 2002 4-5
For each operating mode and/or state, pressingthe Smart Key initiates the displayed functionof that Smart Key. For example, the functionNEXT allows a user to cycle through a seriesof programming states for a given mode ofoperation. The function SELECT enables theuser to enter into the displayed mode or stateof operation. Using this method, the TB84ECAdvantage Series analyzer guides the userthrough the necessary steps use to program ormonitor any given function. A generaldescription of each Smart Key function isgiven in Table 4-1.
MODES OF OPERATION
The Measure Mode is the normal operating modeof the TB84EC Advantage Series analyzer and isthe default mode upon power-up. The MeasureMode is the starting point for entry intoother modes of operation. Each mode containsa unique set of analyzer functions or states.These modes and their related functions arelisted in Table 4-2.
Table 4-2. Mode of Operation Definitions
MODE FUNCTION
Measure Used to display the processand secondary variables - thenormal operating mode for theanalyzer.
Calibrate Used to calibrate input andanalog output functions.
Out/Hold Used for on-line tuning ofanalog output parameters orto manually set the analyzeroutputs, for example, duringmaintenance.
Configure Used to configure analyzerfunctions such as temperaturecompensation, temperaturesensor type, and measurementelectrode type.
MODE FUNCTION
I-E67-84-2B March 25, 2002 4-6
Security Used to enter passwordprotection for the Calibrate,Output/Hold, Configure, andSetpoint/Tune Modes ofOperation.
Display Used to select the variablethat will be shown in thesecondary display region whenthe analyzer is in theMeasure Mode of Operation.
SPT/Tune Used for on-line tuning ofrelay output parameters.
HOLD ICON
The Hold icon energizes when a hold conditionis active. Outputs can be either manually orautomatically held.
Manual activation is accessible in theOutput/Hold Mode of Operation. In this mode,the Hold State permits the output to be heldat the current level and/or state or at alevel and/or state manually set by the user.
When a relay output is configured as aCleaner, an option to enable an automatic holdcondition using the levels and states capturedirectly before initiating the cleaningoperation can be selected. The hold conditiononly occurs during the relay on and recoverytimes and can be separately set for the analogand relay outputs. If desired, the relayoutputs can be disabled instead of held duringa cleaning cycle.
FAULT ICON
The Fault icon energizes when a faultcondition has been detected by the TB84ECAdvantage Series analyzer. Fault conditionsinclude all problem and error detection asoutlined in Section 13, Diagnostics.
I-E67-84-2B March 25, 2002 4-7
SPIKE ICON
The Spike Output function modulates AnalogOutput One from the normal levelrepresentative of the process variable to avalue configured as a set percentage of outputcurrent. When the TB84EC Advantage Seriesanalyzer has detected a fault condition andthe Spike Output function has been enabled,Analog Output One will begin to modulate andthe Spike icon will energize. For moreinformation on Spike Output and Faultconditions, see Section 13, Diagnostics.
RELAY ICONS
The Relay icons are composed of threeindividual icons. Each icon represents one ofthe three integral relay (i.e., Relay One,Relay Two, and Relay Three.) When a relaychanges from its normal state to an energizestate, the corresponding Relay icon alsoenergizes. Since the normal state of eachrelay can be set by a switch, the relay iconwill only inform the user of a state changeand not whether the relay has closed oropened.

I-E67-84-2B March 25, 2002 5-1
SECTION 5 - MEASURE MODE
INTRODUCTION
The Measure Mode is the normal operating modeof the analyzer and is the active mode uponanalyzer power-up. In this mode, the processvariable, output hold state, fault conditionstate, spike output state, relay outputstates, and secondary display information aredisplayed. From the Measure Mode, other modesof operation and fault information can beaccessed.
BOREDOM SWITCH
When entering an operating mode or state andnot returning to the Measure Mode as the finalstep, the TB84EC Advantage Series analyzerautomatically returns to the Measure Mode ofOperation after 20 minutes of unattended use.This feature ensures the analyzer will alwaysbe returned to its normal mode of operation.
PRIMARY DISPLAY
The primary display shows the processvariable. The value of this variable isdependent on the configured analyzer,temperature compensation type, temperaturevalue, solution conductivity, and dampingvalue. The engineering units for the processvariable are dependent only on the configuredanalyzer. Table 5-1 lists the analyzer typesand corresponding engineering units.

Conductivity C mS/cmC µS/cm
Concentration C ppm (parts per million)C ppb (parts per billion)C % (percent)C User Defined
I-E67-84-2B March 25, 2002 5-2
SECONDARY DISPLAY
The secondary display has the ability to showa large variety of information. Since thedisplay area only has six characters, only oneitem can be shown at any given time.Typically, this region will be used fordisplaying the process temperature in degreesCelsius; however, it can be changed to displaythe process temperature in degrees Fahrenheit,output current in milliamperes (i.e., mA) foreach analog output (shown separately), sensorgroup, sensor type, conductivity value andsolute name for a concentration analyzer, andfirmware revision. See Section 10, SecondaryDisplay, for more information.
FAULT INFORMATION Smart Key
Fault information can only be accessed fromthe Measure Mode of Operation and isinterrogated using the FAULT Info Smart Key.A fault condition causes the FAULT icon toblink and the FAULT Info Smart Key to appear.These indicators will be energized as long asthe fault condition is present.
When pressing the FAULT Info Smart Key, thefirst fault condition will be shown in thesecondary display. A short text stringfollowed by the fault code will besequentially shown. Depressing the FAULT InfoSmart Key progressively moves from one faultto the next until all faults have been shown.Once all faults have been interrogated, theFAULT icon will no longer blink and remainsenergized until all fault conditions have beenremoved. If a new fault condition isdetected, the FAULT icon will begin to blinkto inform the user of the newly detectedcondition. For more information on faultconditions and codes, see Section 13,Diagnostics.
SPT Smart Key
The SPT or Setpoint Smart Key provides ashort-cut directly to the SPT/TUNE Mode ofOperation. This short-cut provides quickaccess to tunable relay parameters.
I-E67-84-2B March 25, 2002 5-3
MENU Smart Key
The MENU Smart Key provides access to allother modes of operation. By pressing theMENU Smart Key, the analyzer moves from onemode of operation to the next. Visualfeedback is provided in two manners: the modeindication arrow moves to the next mode ofoperation(e.g., Calibrate) and the secondarydisplay shows the text string representativeof that mode (e.g., CALIBR). Access into thedisplayed mode of operation is allowed usingthe SELECT Smart Key. An escape function tothe Measure Mode of Operation is providedusing the Exit to MEASURE Smart Key.
As seen by the detailed screen flow diagramshown in Figure 5-1, pressing the MENU SmartKey when in the Measure Mode moves the user tothe Calibrate Mode. Once in the CalibrateMode, pressing the Exit to MEASURE Smart Keyreturns the analyzer back to the Measure Mode,pressing the SELECT Smart Key moves theanalyzer into the Calibrate States ofOperation, and pressing the MENU Smart Keymoves the analyzer to the Output/Hold Mode ofOperation. Use Figure 5-1 to identify theSmart Key assignments and the resultingaction.
Each mode of operation contains many statesused to set or tune the TB84EC AdvantageSeries analyzer functions. In the followingsections of this product instruction manual,all modes of operation will be discussed.Screen flow diagrams showing the programmingtext prompts, Smart Key assignment, and theresulting action for each Smart Key are alsoincluded.

When in the Calibrate Mode, the NEXT Smart Keyprovides access to all Calibrate States.Pressing the NEXT Smart Key sequentially movesthe user through each Calibrate State. Thiscycle repeats until a Calibrate State isselected using the SELECT Smart Key, or theescape function is chosen using the Exit ToMEASURE Smart Key. Use Figure 6-1 to identifythe Smart Key assignments and the resultingaction.

The following subsections contain detaileddescriptions of each Calibrate State ofOperation.
Conductivity/Concentration Calibrate State
I-E67-84-2B March 25, 2002 6-3
The Conductivity/Concentration Calibrate Stateis a smart one-point calibration routine thatallows for single- or dual-point calibrations.By initiating calibrations at two differentconductivity values having ample separation,the TB84EC Advantage Series analyzerautomatically adjusts the offset, slope, orboth in order to obtain the best sensorperformance. Since this routine only uses themost recent calibration data, calibration canbe conducted throughout the sensor's life thusensuring consistent sensor performance. If anincorrect calibration has been entered, theReset Calibrate State provides the ability toreturn analyzer calibration to factorysettings. See Reset Calibrate State in thissection.
Note: The Reset Calibration State will reset allcalibration values including the temperaturesensor; therefore, calibration of thetemperature sensor is required after performinga Reset Calibration.
Since the TB84EC Advantage Series analyzer canbe configured as a Conductivity orConcentration analyzer, the smart one-pointcalibration routines will automatically setthe units of calibration to be the same asthose for the measured process variable.Thus, a Conductivity Analyzer usesconductivity units and a ConcentrationAnalyzer uses the user-defined units set inthe Configure Mode of Operation.
Conduct a Conductivity or ConcentrationCalibration using the following procedure:
1) Once the sensor has been installed andhas reached the temperature of theprocess solution, verify the processvariable value using a grab sample and anexternal instrument having the same typeof temperature compensation.
2) S e l e c t C O N . C A L ( i . e . ,Conductivity/Concentration CalibrateState) in the Calibrate Mode of Operationusing the SELECT Key.
3) Confirm the displayed reading is STABL?

(i.e., stable) using either the YES or NOKey. If the NO Key is pressed, theTB84EC Advantage Series analyzer willreturn to the Conductivity/ConcentrationCalibrate State (i.e., CON.CAL). For anunstable condition, conduct one or moreof the following steps:
a) Wait until the process liquidcomposition stabilizes,
b) Check to see if the TB84ECAdvantage Series analyzer hasdetected a Fault condition bylooking for the Fault icon on theLCD. Interrogate the fault byescaping to the Measure Modeusing the Exit to MEASURE Key andthe FAULT Info Key in that order.
c) See Section 13, Troubleshooting.
4) If the YES Key is pressed, enter the NEWVAL (i.e., new process variable) thatreflects the difference between the grabsample value and the indicated value whenthe grab sample was taken (i.e., CurrentTB84 Indication + [Grab Sample Value -TB84 Indication at the time the grabsample was taken]). Use the Key toincrement the digit value and the Keyto move to the next digit and/or unit ofconductivity. Press the ENTER Key toenter the new value.
Invalid new calibration values will generatethe text string BAD.CAL, and the calibrationvalue will not be accepted. If the new valueis valid, the Slope value will be shown.Pressing the NEXT Smart Key displays theOffset value. At this point, the user canreturn to the Conductivity/ConcentrationCalibrate State by pressing the NEXT Key or tothe Measure Mode by pressing the Exit ToMEASURE Key.
I-E67-84-2B March 25, 2002 6-5
Temperature Calibrate State
The Temperature Calibrate State is a smartcalibration routine that allows for bothsingle- and dual-point calibration. Bycalibrating the temperature at two pointswhich are at least 20 C apart, the TB84ECo
Advantage Series analyzer automaticallyadjusts the offset and/or slope. Since thisroutine only uses the most recent calibrationdata, calibrations can be conducted throughoutthe sensor’s life to ensure accuratemeasurement of the temperature sensing device.If an incorrect calibration has been entered,the Reset Calibrate State can restore thecalibration to factory settings. See ResetCalibrate State in this section.
Note: The Reset Calibrate State will reset allcalibration values including the process sensor;therefore, the process sensor will requirecalibration after performing a ResetCalibration.
Conduct a Temperature Calibration using Figure6-3 and the following procedure:
1) Before installing the sensor into itsfinal installed location, allow thesensor to reach ambient temperature.
2) Select the Temperature Calibrate State ofOperation using the SELECT Key.
3) Set the engineering unit by pressing the Key to toggle the unit between C (i.e.,o
degrees Celsius) or F (i.e., degreeso
Fahrenheit), and press the ENTER Key touse the displayed engineering unit.
4) Confirm the displayed reading is STABL?(i.e., stable) using either the YES or NOKey. If the NO Key is pressed, theTB84EC Advantage Series analyzer willreturn to the Temperature CalibrateState. For an unstable condition,conduct one or more of the followingsteps:

For such acircumstance, the calibration data from oneanalyzer can be transfered to the others.Also, manually entered calibration values canprovide enough accurancy for someinstallations or provide a good starting pointbefore a formal calibration can be initiated.Nominal sensor slope values are:
Sensor Group Slope
A 0.70
B 0.80
C 1.25
Reset Calibrate State
The Reset Calibrate State sets all calibrationdata (i.e., sensor and temperature) to factoryvalues. This state purges calibration historyand should be initiated before calibrating anew sensor.
I-E67-84-2B March 25, 2002 6-9
When interrogating the calibration valuesafter a reset has been performed, the slopeand offset values for both the sensor andtemperature will be set to 1.000 and 0.000,respectively.
Conduct a Reset Calibrate using the followingprocedure.
1) Select the Reset Calibrate State ofOperation using the SELECT Key.
2) Confirm or refuse the RESET? operationusing either the YES or NO Key,respectively.
Note: The Reset Calibration State will reset allcalibration values; therefore, the processsensor and temperature sensor will requirecalibration after performing a ResetCalibration.
Analog Output One Calibrate State
The Analog Output One Calibrate State trimsthe output signal to maintain precisetransmission of the process variable to thefinal monitoring system. Though the TB84ECAdvantage Series analyzer output current isfactory calibrated, the output can be trimmedto compensate for other input/output devices.

If a hold condition(s) already exists and theuser selects the Hold State of Operation, theTB84EC Advantage Series analyzer will requestwhether all hold conditions should be released(i.e., REL.HLD). Press the YES Key if allhold conditions should be released and the NOKey to edit the existing hold conditions.
Analog Output One Rerange State
The Analog Output One Rerange Output/HoldState provides the ability to change theoutput range of Analog Output One. One orboth end point values can be changed to anyvalue or range of values that are within thespecifications listed in Table 1-3.
If a non-linear output is configured,reranging the end point values will affect thenon-linear relationship. Since the non-linearrelationship is set as a percentage inputagainst a percentage output, changing the endpoint values should accompany a review of thebreak point relationship. See Section 8,Configure Mode, for information on viewing andmodifying the non-linear break points.
I-E67-84-2B March 25, 2002 7-7
Conduct a Rerange of the output values usingthe following procedure:
1) Select the Rerange State of Operationusing the SELECT Key.

Damping State
The Damping State applies a lag function onthe input signal for Basic configuration orcan apply different lag functions to thedisplay process variable, Analog Output One,and Analog Output Two for Advancedconfigurations. The Damping function reducesthe fluctuations caused by erratic processconditions. Damping values can be set from0.0 to 99.9 seconds and represent the timerequired to reach 63.2% of a step change.
For Basic configurations, the damping value isapplied to the analyzer’s input signals. Inthis case, damping will be applied to thedisplayed process variables and analogoutputs. For Advanced configurations,different damping values can be applied toeach output element (i.e., the displayedprocess variables, Analog Output One, andAnalog Output Two.)

SECTION 8 - CONFIGURE MODE
INTRODUCTION
The Configure Mode of Operation establishesthe operating parameters of the TB84ECAdvantage Series analyzer. These parametersinclude programming type, analyzer type,sensor type, temperature compensation type,analog output ranges, relay output parameters,damping value(s), diagnostic functionality,safe mode levels, and spike magnitude (i.e.,level).
A description of each configuration item andrelated parameters will be included. Revieweach of the following sections beforeconfiguring the TB84EC Advantage Seriesanalyzer.
PRECONFIGURATION DATA REQUIRED
Before attempting to configure the TB84ECAdvantage Series analyzer, the followingrequirements must be defined.
1. Analyzer parameters.
2. Analog Output Range values.
3. Relay Output function and parameters.
4. Security requirements.
5. Sensor Diagnostic functionality.

set and saved into memory. In order toprovide the ability to secure the ModifyConfigure State yet leave the ability to viewconfiguration information, the View ConfigureState can be entered without using a securitycode.
Figure 8-1. Screen Flow Diagram ForModify/View and Basic/Advanced ConfigureStates of Operation.
As seen in Figure 8-1, the TB84EC AdvantageSeries analyzer queries if the user would liketo Modify the configuration. Pressing the YESSmart Key moves the user into the ModifyConfigure State, pressing the NO Smart Keymoves the user to the View configurationquery, and pressing the Exit To MEASURE SmartKey escapes to the Measure Mode.
I-E67-84-2B March 25, 2002 8-3
If a configuration requires modification andthe user is in the View Configure State,access to the Modify Configure State isprovided through a HotKey function. TheHotKey links the View Configure State to theModify Configured State using the ENTER SmartKey. For example, the TMP.SNS (i.e.,temperature sensor) in the View ConfigureState can be modified from PT 100 to None bypressing the ENTER Smart Key when viewing thePT 100 option. An intermediate confirmationscreen will query the user on their desire tomodify this option using the YES and NO SmartKeys. If the Modify Configure State has beensecured, the security code will be requested.Upon entering the correct code or if theModify Configure State has not been secured,the TB84EC Advantage Series analyzer will godirectly to TMP.SNS Modify Configure State andallow the user to change the temperaturesensor type. After completing the change,pressing Exit To MEASURE Smart Key moves theuser to the configuration SAVE? State.Pressing the YES Smart Key saves the newtemperature sensor option and returns theanalyzer to the Measure Mode.
BASIC/ADVANCED PROGRAMMING MODE
The Configure Mode is split into twoprogramming groups: Basic and Advanced. Thesetwo options are specified by nomenclature andcontrol the number of configuration optionsavailable in the Modify Configure State.
The Basic Programming Mode contains a subsetof configuration options found in the Advancedmode. Separation into two programming groupsis advantageous when limited functionality isdesired. Fewer options reduces confusion andthe possibility of configuration errors.
When Advanced programming is ordered, theprogramming toggle (i.e., Basic/Advanced) mustbe set in two locations: the User State in theUtility Mode and the Modify Configure State inthe Configure Mode. In order to select eitherthe Basic or Advanced Programming Mode in theModify Configure State, the Programming Modemust be set to Advanced in the User State.
I-E67-84-2B March 25, 2002 8-4
See Section 11, Utility Mode, for moreinformation on setting the User Stateprogramming mode to Advanced.
When in the Configure Mode and Advancedprogramming has been set in the User State,the TB84EC Advantage Series analyzer queriesif the user would like Basic programming.Pressing the ENTER Smart Key moves the user tothe Modify Configure States, pressing the NEXTSmart Key moves the user to the Advancedprogramming query, and pressing the Exit ToMEASURE Smart Key escapes to the Measure Mode.To set the analyzer to Advanced programming,the user presses the ENTER Smart Key whenqueried to set the programming to Advanced.See Figure 8-1 for the corresponding screenflows.
MODIFY CONFIGURE STATES OF OPERATION
Since the View Configure State only displaysthe configured options, the followingsections will strictly focus on each ModifyConfigure State and the available options forthese states.
The Modify Configure State contains all theavailable settings that establishes thefunctionality of the TB84EC Advantage Seriesanalyzer. Upon receipt of the analyzer, thedefault configuration (unless otherwisespecified by the customer when ordering theTB84EC Advantage Series analyzer) will be usedonce the analyzer has been powered. See thePreface or Appendix C for the defaultconfiguration settings.
Before installing the analyzer, theconfiguration should be modified to reflectthe final installed application. The ModifyConfigure States define the analyzer type,sensor interface, output parameters, anddiagnostic functionality. Table 8-1 describeseach of these programming modes and theirfunction.

The following subsections contain detaileddescriptions of each Modify Configure State ofOperation.
I-E67-84-2B March 25, 2002 8-8
Analyzer State (Basic/Advanced)
The Analyzer State determines the type ofanalyzer and sensor. Table 8-2 describes thefunction and programming mode of each state.
Table 8-2. Analyzer States
State Function ProgrammingMode
Conductivity Used to measure the conductivity Basic/Advancedof a solution. Process variableengineering units are mS/cm andµS/cm.
Concentration Used to measure the conductivity Advancedof a solution and convert thisnon-specific measurement to aspecific solute concentration.Process variable engineeringunits are %, ppm, ppb, and user-defined.
Conductivity Analyzer State (Basic/Advanced)
The Conductivity Analyzer State contains threechoices that corresponds with the type offour-electrode sensor group: A, B, or C. TheSensor Group identifies the sensor’s cellconstant and conforms to the conductivityranges specified in Table 1-3. Since the cellconstant is influenced by surface area of theelectrodes, the physical orientation of thefinal sensor installation, and the measuredsolution voltage set by the electronics, ABBfour-electrode sensors are the onlyrecommended sensor for use with the TB84ECAdvantage Series analyzer.
Configure a Conductivity Analyzer State usingthe following procedure:1) Select the ANALZR (i.e., Analyzer) State
in the Configure Mode of Operation usingthe SELECT Key.
2a) If the Programming Mode is set to Basic,the TB84EC Advantage Series analyzer goesdirectly to the sensor type options.Skip to step 3.
I-E67-84-2B March 25, 2002 8-9
2b) If the Programming Mode is set toAdvanced, choose the COND State by usingthe NEXT Key to toggle between COND andCONCEN (i.e., Conductivity andConcentration, respectively). Once thecorrect option is display, press theENTER Key to accept the choice.
Note: CONCEN State is only available when theAdvanced Programming State has been purchasedand selected. See Section 11, Utility Mode,for Programming Mode selection.
3) Set the sensor group by using the NEXTKey to scroll through the three sensorgroups: A GRP, B GRP, and C GRP. Oncethe correct option is displayed, pressthe ENTER Key to accept the choice.
Concentration State (Advanced)
The Concentration State converts conductivityvalues to concentration units. This stateapplies temperature-compensated conductivitymeasurements to a pre-defined or user-definedfunction that converts the conductivitymeasurements to concentration values having afixed decimal point location (i.e., automaticdecimal point ranging is not support).
The Concentration State provides the followingpre-defined configurations:
! 0 to 15% Sodium Hydroxide (NaOH)! 0 to 20% Sodium Chloride (NaCl)! 0 to 18% Hydrochloric Acid (HCl)! 0 to 20% Sulfuric Acid (H SO )2 4
These pre-defined configurations are based ondata contained in the International CriticalTables. For more information, see Appendix B,Concentration Programming.
The user-defined configuration providescapability for selecting an Engineering Uniticon, decimal point position, custom textdescription, and six-point linear curve fit.The Engineering Unit icon options includepercent (i.e., %), parts-per-million (i.e.,ppm), parts-per-billion (i.e., ppb), and noEngineering Unit icon.
I-E67-84-2B March 25, 2002 8-10
The six-point linear curve fit sets the end-point and break-point values of the desiredconductivity-to-concentration conversion. Theend-point values define the full-scale outputrange, and the break-points identify thetransition points between the five linesegments defining the conductivity-to-concentration curve.
To define the end-points and break-points, aplot of temperature-compensated conductivityagainst solute concentration must be dividedinto five line segments that best approximatethe shape of the conductivity-to-concentrationcurve. The beginning of the first and end ofthe fifth line segment identify the end-pointsof the linear approximation and output range.
Table 8-3 and Figure 8-3 show example data andthe linear approximation for 0 to 45% NH NO .4 3
As can be seen by this example, theconductivity-to-concentration curve is a non-linear function which has been divided intofive line segments. The end-points representPoint Numbers 1 and 6, while the break-pointsrepresent Point Numbers 2 through 5. Alsonote, the analyzer output is linear relativeto the solute concentration (i.e., AmmoniumNitrate concentration). Since the end-points(i.e., Point Numbers 1 and 6) define the full-scale output range, rerange of the outputvalues is restrained to the range betweenthese points (i.e., 0 and 45% AmmoniumNitrate). For more information, see AppendixB, Concentration Programming.

Temperature Sensor State (Basic/Advanced)
The Temperature Sensor State configures thetemperature input for a Pt100, 3 kohm Balco,4.75 kohm Network, or none. When the "NONE"option is entered, the temperature andtemperature compensation will be fixed at 25 Co
and MANUAL, respectively. To change the fixedtemperature, a temperature calibration to thedesired temperature value is required.
Set the Temperature Sensor State using thefollowing procedure.
1) Select the TMP.SNS (i.e., TemperatureSensor) State in the Configure Mode ofOperation using the SELECT Key.
2) Choose the desired temperature sensor byusing the NEXT Key to toggle betweenNONE, 3K.BLCO (i.e., 3 kohm Balco),PT100, and 4.7K.RTD (i.e., 4.75 kohmNetwork). Enter the option by using theENTER Key when the correct sensor isdisplayed in the secondary display.
Temperature Compensation State (Basic/Advanced)
Temperature has a marked effect on theconductance of many solutions. The effect isgenerally nonlinear and dependent on the typesof ions and their concentration.
I-E67-84-2B March 25, 2002 8-14
The TB84EC Advantage Series analyzer containsa number of preprogrammed correctionalgorithms that compensate the effect oftemperature on conductivity to a referencetemperature of 25 C. Thus, the displayed ando
transmitted process variable can be accuratelydetermined as the process temperature varies.
For the Advanced Programming Mode, thereference temperature can be set to valuesother than 25 C. Valid reference temperatureo
values are limited to the displayedtemperature range as listed in the Table 1-3,Specifications.
The options for temperature compensation aregrouped into two sets: MANUAL and AUTO (i.e.,Automatic). MANUAL temperature compensationdoes not contain any additional options and islocked to a specific process temperatureindependent of the selected temperaturesensor. If a different process temperature isdesired, the new temperature can be set usinga temperature calibration and will be used totemperature compensate the process variable tothe reference temperature.
The AUTO compensation options are sensor groupdependent and use the temperature valuesmeasured by input from the temperature sensorthat is either integral or external to thesensor. Within the AUTO State, compensationalgorithms include Standard KCl (0.1N KClbased), Solution Coefficient, 0 to 15% NaOH, 0to 20% Sodium Chloride, 0 to 18% HydrochloricAcid, 0 to 20% Sulfuric Acid, Pure WaterNeutral, Pure Water Acid, Pure Water Base, andUser-Defined.
The User-Defined temperature compensationoption requires uncompensated conductivitydata on a representative sample of the processsolution ranging from the referencetemperature of 25EC to the maximum processtemperature. With this data, the ratio ofuncompensated conductivity to conductivity atthe reference temperature of 25EC iscalculated. Using these values, the ratiosare plotted against temperature.

Table and Figure 8-4 shows an example of atypical user-defined temperature compensationplot. As seen in this example, the non-linearplot is segmented into five linear sections.The end-points (i.e., columns 1 and 3 of Table8-4) of each section are used to define thebreak-points for the user-defined temperaturecompensation option. Each set of point areentered in sequence from the lowest to thehighest (e.g., 0EC/0.70 for TMP1EC/K1/K25,25EC/1.00 for TMP2EC/K2/K25, ..., 200EC/0.88for TMP6EC/K6/K25).

Linear Output State (Basic/Advanced)
The Linear Output State establishes the lowerand upper range values. The default valuesfor the output represent the full scaleprocess variable range. See Table 1-3,Specifications, for full scale variableranges.
For a reverse acting output, reverse the zeroor four and 20 milliampere values (e.g., 199.9mS/cm for the zero or four milliampere valueand 0 mS/cm for the 20 milliampere value).
Figure 8-5. Screen Flow Diagram For AnalogOutput One Configure State of Operation.
Set the Linear Output State using Figure 8-5as reference and the following procedure:
I-E67-84-2B March 25, 2002 8-20
1) Select the AO1.OUT State in the ConfigureMode of Operation using the SELECT Key.
2) Set the output span using the NEXT Key totoggle between 4-20MA and 0-20MA, andpress the ENTER Key to enter the desiredspan.
3) Set the process variable value for the 0or 4 milliampere point using the Keyto increment the blinking digit and the Key to move to the next digit, and
press the ENTER Key to enter the desiredvalue.
4) Set the process variable value for the 20milliampere point using the Key toincrement the blinking digit and the Key to move to the next digit, and pressthe ENTER Key to enter the desired value.
5) Select the LINEAR Output State using theSELECT Key for Advanced configurations.For Basic configurations, this step willnot be accessible.
Non-Linear Output State (Advanced)
The Non-Linear Output State sets the end pointand break point values for a non-linear outputfunction. The default values for the outputrepresent the full scale process variablerange (e.g.,0 to 199.9 mS/cm) and the breakpoints are set for a linear output (e.g., 20%input equals 20% output).
To define the break point values, a plot ofthe process variable against the desiredoutput (or variable that represents the outputvalue) must be segmented into six linearregions that best fit the non-linearrelationship. The points where the linearregions intersect should fall on the non-linear function and represent the break pointsthat are entered into Non-Linear Output State.
I-E67-84-2B March 25, 2002 8-21
As with the Linear Output State, the outputrange must be defined and will represent the0% input/0% output and 100% input/100% outputpoints. Since the 0% and 100% points aredefined by the output range, the break pointinformation (e.g., X-1/Y-1, X-2/Y-2, etc.values) should not include the 0% input/0%output and 100% input/100% output values. Thebreak points must be entered as percentage ofinput range and output span. Also as with alinear output, a reverse acting non-linearoutput can be implemented by reversing thezero or four and 20 milliampere processvariable and break point values (e.g., 199.9mS/cm for the 0 or 4 milliampere value and 0mS/cm for the 20 milliampere value).
Set the Analog Output One Non-Linear Stateusing Figure 8-5 as a reference and thefollowing procedure:
1) Select the AO2.OUT State in the ConfigureMode of Operation using the SELECT Key.
2) Set the output span using the NEXT Key totoggle between 4-20MA and 0-20MA, andpress the ENTER Key to enter the desiredspan.
3) Set the process variable value for thezero or four milliampere point using the Key to increment the blinking digit andthe Key to move to the next digit, andpress the ENTER Key to enter the desiredvalue.
4) Set the process variable value for the 20milliampere point using the Key toincrement the blinking digit and the Key to move to the next digit, and pressthe ENTER Key to enter the desired value.
4) Select the NON.LIN Output State by usingthe NEXT Key to change the programmingstate from LINEAR to NON.LIN and pressingthe SELECT Key to accept the NON.LINOutput State.
I-E67-84-2B March 25, 2002 8-22
5) Set the input percentage for the firstbreak point (X-1) using the Key toincrement the blinking digit and the Key to move to the next digit, and pressthe ENTER Key to enter the new value.
6) Set the output percentage for the firstbreak point (Y-1) using the Key toincrement the blinking digit and the Key to move to the next digit, and pressthe ENTER Key to enter the new value.
7) Repeat steps 5 and 6 for the remainingfour break points.

Setpoint Relay Output (Basic/Advanced)
A Setpoint Relay Output can be configured toenergize when the Process Variable orTemperature exceeds or falls below a definedlevel (i.e., a High or Low Setpoint,respectively). Valid Setpoint values arelimited to the Process Variable and/orTemperature ranges of the TB84EC AdvantageSeries analyzer. See Table 1-3,Specifications, for analyzer range values.
I-E67-84-2B March 25, 2002 8-30
To prevent relay chatter, a Setpoint RelayOutput has an configurable Deadband. TheDeadband control keeps the relay energizeduntil the Process Variable or Temperature hasdecreased below a High Setpoint value or abovea Low Setpoint value by the Deadband value.Valid Deadband values are 0.0 to 200 mS/cmfor Group A Sensors, 0.00 to 20.0 µS/cm forGroup B Sensors, 0.000 to 20.0 µS/cm for GroupC Sensors, O to 10% of the configuredConcentration range for Concentrationconfigurations, and 0 to 10 C (18 F) foro o
Temperature sources.
A Time Delay control also refines the functionof a Setpoint Relay. Entering a Time Delayvalue greater than 0.0 minutes enables awaiting period before energizing the relayonce the setpoint condition has been met.Valid Time Delay values are 0.0 to 99.9minutes.
Set the Setpoint parameters of a Relay Outputusing Figure 8-11 as reference and thefollowing procedure:
1) Set the Setpoint activation condition(i.e., LO SPT or HI SPT) using the Keyto increment the blinking digit and the Key to move to the next digit, and
press the ENTER Key to enter the newvalue.
2) Set the Deadband (i.e., DBAND) using the Key to increment the blinking digit andthe Key to move to the next digit and,press the ENTER Key to enter the newvalue.

As with a Setpoint Relay Output, the Setpointcondition functions in the same manner;however, the Deadband control is replaced withthe Cycle Time. Thus, a Cycle Timer willenergize the Relay Output for a set amount oftime (ON.TIME) and de-energize for theremainder of the cycle (CYC.MIN). This cyclerepeats until the Setpoint condition is nolonger met. For more information on the CycleTimer, see Section 2, Overview.
Valid Setpoint values are limited to theProcess Variable range of the TB84EC AdvantageSeries analyzer. See Table 1-3,Specifications, for analyzer range values.Valid Cycle Time and On Time values are 0.0 to99.9 minutes.

press the ENTER Key to enter the newvalue.
2) Set the Cycle Time in minutes (i.e.,CYC.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.
3) Set the On Time in minutes (i.e., ON.MIN)using the Key to increment theblinking digit and the Key to move tothe next digit, and press the ENTER Keyto enter the new value.
Cleaner Relay Output (Advanced)
Automatic sensor cleaning can be accomplishedusing any one of the three relay outputs. Ata prescribed time interval, a Cleaner RelayOutput will energize and allow the activationof a cleaning device. While in the energizedstate, analog and relay outputs can be held tovalues captured just prior to the cleaningcycle (i.e., energized state). If a relayhold condition is not feasible, non-cleanerrelay outputs can be disable during a cleaningcycle.
To specify a cleaning cycle, the Cycle, On,and Recovery Times must be defined. The CycleTime defines the repeating period betweencleaning cycles, the On Time defines thelength of time the relay will be energized,and the Recovery Time defines the length oftime after the relay has been de-energizedbefore the hold and/or disable condition(s)will be removed. Valid times for Cycle Timeare 0.0 to 99.9 hours and for On and RecoveryTimes are 0.0 to 99.9 minutes.
I-E67-84-2B March 25, 2002 8-35

The SpikeMagnitude is entered as a percentage ofthe 16 milliampere output range for afour to 20 milliampere output or 20milliampere output range for a zero to 20milliampere output (e.g., 10% willgenerate a 1.6 milliampere spike for afour to 20 milliampere output range).
Note: Once the Spike State is OFF in theOutput/Hold Mode of Operation, changing theconfigured spike level in the Configure Modewill not reenable the Spike State. The SpikeState can only be turned ON or OFF in theOutput/Hold Mode of Operation.
CONFIGURATION LOCKOUT
The TB84EC Advantage Series analyzer has alockout feature that, once engaged, prohibitsaccess to the Configure Mode. This featuredoes not affect parameters that can be changedin the other modes of operation includingCalibrate, Output/Hold, Security, secondaryDisplay, and Setpoint/Tune.
To enable the lockout feature, change jumperW1 on the Microprocessor/Display PCB from pins1 and 2 (i.e., position A - the factorydefault position) to pins 2 and 3 (i.e.,position B). Use Figure 8-16 and Section 16,Replacement Procedures, for jumper positionsand circuit board handling procedures.

SECTION 11 - SETPOINT/TUNE MODE
INTRODUCTION
The Setpoint/Tune Mode of Operation provides adirect method to tune relay output parameters.Though this mode of operation can not be usedto change the function a relay, it doesprovide the ability to quickly change relayparameters pertinent to process control. Tochange the relay output function, see Section8, Configure Mode.
SETPOINT/TUNE STATES OF OPERATION
The Setpoint/Tune Mode consists of threestates of operation: RELAY1, RELAY2, andRELAY3. Each state provides the ability toupdate operational parameters for theconfigured relay functions. For instead ifRelay Output One is configured to function asa High Process Variable Setpoint, theSetpoint, Deadband, and Time Delay will betunable parameters available in theSetpoint/Tune Relay One State of Operation.
Since the tunable parameters are dependent onthe configured relay function, the followingsections will only describe the adjustment ofthese parameters.
Setpoint Relay Output (Basic/Advanced)
A Setpoint Relay Output can be configured toenergize when the Process Variable orTemperature exceeds or falls below a definedlevel (i.e., a High or Low Setpoint). ValidSetpoint values are limited to the ProcessVariable and/or Temperature ranges of theTB84EC Advantage Series analyzer. See Table1-3, Specifications, for analyzer rangevalues.
I-E67-84-2B March 25, 2002 11-2
To prevent relay chatter, a Setpoint RelayOutput has an configurable Deadband. TheDeadband control keeps the relay energizeduntil the Process Variable or Temperature hasdecreased below a High Setpoint value or abovea Low Setpoint value by the Deadband value.Valid Deadband values are 0.0 to 200 mS/cmfor Group A Sensors, 0.00 to 20.0 µS/cm forGroup B Sensors, 0.000 to 20.0 µS/cm for GroupC Sensors, O to 10% of the configuredConcentration range for Concentrationconfigurations, and 0 to 10 C (18 F) foro o
Temperature sources.
A Time Delay control also refines the functionof a Setpoint Relay. Entering a Time Delayvalue greater than 0.0 minutes enables awaiting period before energizing the relayonce the setpoint condition has been met.Valid Time Delay values are 0.0 to 99.9minutes.
Set the Setpoint parameters of a Relay Outputusing Figure 11-1 as a reference and thefollowing procedure:
1) Set the Setpoint activation condition(i.e., LO SPT or HI SPT) using the Keyto increment the blinking digit and the Key to move to the next digit, and
press the ENTER Key to enter the newvalue.
2) Set the Deadband (i.e., DBAND) using the Key to increment the blinking digit andthe Key to move to the next digit and,press the ENTER Key to enter the newvalue.
3) Set the Time Delay in minutes (i.e.,DLY.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.

As with a Setpoint Relay Output, the Setpointcondition functions in the same manner;however, the Deadband control is replaced withthe Cycle Time. Thus, a Cycle Timer willenergize the Relay Output for a set amount oftime (ON.TIME) and de-energize for theremainder of the cycle (CYC.MIN). This cyclerepeats until the Setpoint condition is nolonger met. For more information on the CycleTimer, see Section 2, Overview.
Valid Setpoint values are limited to theProcess Variable range of the TB84EC AdvantageSeries analyzer. See Table 1-3,Specifications, for analyzer range values.Valid Cycle Time and On Time values are 0.0 to99.9 minutes.
Figure 11-3. Screen Flow Diagram For Settingthe Cycle Timer Relay Output Configure Stateof Operation.
I-E67-84-2B March 25, 2002 11-6
Set the Cycle Timer parameters of a RelayOutput using Figure 11-3 as reference and thefollowing procedure:
1) Set the Setpoint activation condition(i.e., LO SPT or HI SPT) using the Keyto increment the blinking digit and the Key to move to the next digit, and
press the ENTER Key to enter the newvalue.
2) Set the Cycle Time in minutes (i.e.,CYC.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.
3) Set the On Time in minutes (i.e., ON.MIN)using the Key to increment theblinking digit and the Key to move tothe next digit, and press the ENTER Keyto enter the new value.
Cleaner Relay Output (Advanced)
Automatic sensor cleaning can be accomplishedusing any one of the three relay outputs. Ata prescribed time interval, a Cleaner RelayOutput will energize and allow the activationof a cleaning device. While in the energizedstate, analog and relay outputs can be held tovalues captured just prior to the cleaningcycle (i.e., energized state). If a relayhold condition is not feasible, non-cleanerrelay outputs can be disable during a cleaningcycle.
To specify a cleaning cycle, the Cycle, On,and Recovery Times must be defined. The CycleTime defines the repeating period betweencleaning cycles, the On Time defines thelength of time the relay will be energized,and the Recovery Time defines the length oftime after the relay has been de-energizedbefore the hold and/or disable condition(s)will be removed. Valid times for Cycle Timeare 0.0 to 99.9 hours and for On and RecoveryTimes are 0.0 to 99.9 minutes.
I-E67-84-2B March 25, 2002 11-7
Set the Cleaner parameters of a Relay Outputusing Figure 11-4 as reference and thefollowing procedure:
1) Set the Cycle Time in hours (i.e.,CYC.HRS) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.
2) Set the On Time in minutes (i.e., ON.MIN)using the Key to increment theblinking digit and the Key to move tothe next digit, and press the ENTER Keyto enter the new value.
3) Set the Recovery Time in minutes (i.e.,RCV.MIN) using the Key to incrementthe blinking digit and the Key to moveto the next digit, and press the ENTERKey to enter the new value.

SECTION 12 - UTILITY MODE
INTRODUCTION
The TB84EC Advantage Series analyzer containsa Utility Mode of Operation that providesaccess to powerful functions not used duringnormal operating conditions. These functionshave been separated into two categories:Factory and User. Factory functions arestrictly reserved for ABB personnel.
User functions include Programming Mode, resetconfiguration to default settings, removesecurity, reset all parameters to defaultsettings, and software reboot functions.
FACTORY/USER STATE
The Factory and User States of Operation canbe accessed using the hidden fifth key locatedtop, center on the keypad. Once the hiddenkey has been pressed, the textual prompt USERwill be displayed in the secondary displayregion. Pressing the SELECT Smart Key bringsthe user into the User State, pressing theNEXT Smart Key brings the user to the Factoryselection, and pressing the Exit to MEASURESmart Key escapes back to the Measure Mode.
User State
The User State contains the primary toggle forsetting the Programming Mode, three resetfunctions, and a software reboot operationthat initiates the self-test mode. Table 12-1describes the function of each User State.
The NEXT Smart Key sequentially moves througheach of the four User States. This cyclerepeats until a state is selected or theescape function is chosen using the Exit toMEASURE Smart Key. To select a state, pressthe SELECT Smart Key when the desired UserState is shown in the secondary displayregion.

SECTION 13 - DIAGNOSTICS
INTRODUCTION
The TB84EC Advantage Series analyzer performsa number of diagnostic checks on hardware,firmware, and sensor functions. If anonconforming condition is detected, the useris alerted to faults locally by a flashingFAULT indicating icon and, if configured,remotely by modulating Analog Output One(i.e., Spike Output) and/or energizing a RelayOutput (i.e., Diagnostic Relay Output).
Diagnostic faults are interrogated using theFAULT Info Smart Key. A short text string andfault code are alternately shown in thesecondary display region. If multiple faultsexist, the FAULT Info Smart Key moves the userto the next fault. Once all faults have beeninterrogated, the analyzer returns to theMeasure Mode of Operation.
The following section describes the types offault conditions and their applicability tothe TB84EC Advantage Series functionality.
FAULT CODES
Fault conditions are grouped into twocategories based on severity. Conditions thatresult in degradation of analyzer performanceare reported as Problem Codes (PC), whileconditions that render the analyzer inoperableare reported as Error Codes (EC).
Fault codes are reported in the secondarydisplay region in a first in, first out order(i.e., the first detected fault condition isthe first condition that is displayed uponinterrogation). All active fault conditionscan be viewed at any time while in the MeasureMode using the FAULT Info Smart Key. Aflashing Fault icon indicates a new faultcondition that has not been interrogated. Anon-flashing Fault icon indicates all faultconditions have been interrogated but notresolved. When all fault conditions areresolved, the Fault icon and FAULT Info SmartKey are de-energized.
I-E67-84-2B March 25, 2002 13-2
Problem Codes
Problem Codes result from fault conditionsthat impact the performance of the TB84ECAdvantage Series analyzer. In most cases,these conditions can be resolved by the userusing standard practices.
The occurrence of a Problem Code faultcondition triggers the Fault icon to energize,the Spike output to modulate (if configured),and a Diagnostic Relay Output to energize (ifconfigured). These diagnostic indicatorsprovide local and remote reporting capability.
Tables 13-1 and 13-2 contain all the ProblemCodes supported by the TB84EC Advantage Seriesanalyzer. Each entry lists the Problem Codenumber, displayed text string, and a shortdescription of the fault. See Section 14,Troubleshooting, for resolving a faultcondition.

Error Codes
Error Codes result from fault conditions thatrender the TB84EC Advantage Series analyzerinoperable. In most cases, these conditionscan not be resolved by the user using standardmethods.
The occurrence of an Error Code faultcondition triggers the Fault icon to energizeand the Safe Mode outputs to enable (i.e., theAnalog Output One and Two currents are fixedhigh or low based on the configured Safe Modelevels). These diagnostic indicators providelocal and remote reporting capability.

Calibration Diagnostic Messages
The TB84EC Advantage Series analyzer performsautomatic efficiency and offset calculationsrelative to a theoretically perfectconductivity and/or temperature sensor duringeach calibration cycle. Calibration constantsare retained for future interrogation usingthe Edit Calibrate State. The calibrationconstants that are displayed are Slope andOffset for the Process Variable and Slope andOffset for the Temperature.
A Slope of less than 0.2 or greater than 5indicates a potentially bad processcalibration point or poorly performing sensor.In these cases, the text string BAD.CAL (i.e.,bad calibration) is displayed in the secondarydisplay region. The user is returned to thebeginning of the calibration cycle after thebad calibration has been reported.
An Offset value of less than -20 µS/cm forSensor Group A, -4 µS/cm for Sensor Group B,and -0.800 µS/cm or greater than 20 µS/cm forSensor Group A, 4 µS/cm for Sensor Group B,and 0.800 µS/cm for Sensor Group C alsoindicates a potentially bad processcalibration or poorly performing sensor.Again, a bad calibration will be reported, andthe user returned to the beginning of thecalibration cycle.
I-E67-84-2B March 25, 2002 13-6
For temperature, a bad calibration will bereported and calibration values will not beaccepted for Slope values that are less than0.2 or greater than 1.5 and Offset values thatare less than -40 C or greater than +40 C. Aso o
with conductivity calibrations, temperaturecalibrations use smart software routines thatautomatically adjust the Slope, Offset, orboth values based on the calibration valuebeing entered and calibration history if itexists.
Additional Diagnostic Messages
Other diagnostic messages may appear duringanalyzer programming. These messages includeBAD.VAL (i.e., bad value) and DENIED. BAD.VAL indicates the attempted numeric entryof a value which is out of the allowedanalyzer range. See Table 1-3,Specifications, for analyzer range limits.
DENIED indicates incorrect entry of a securitypassword. See Section 9, Security Mode, forinformation on the Security Mode of Operation.
RAM.ERR indicates a Random Access Memoryread/write error. The analyzer willautomatically reset when this error has beenencountered. If the analyzer continues toreset, contact ABB for problem resolution.

WARNING All error conditions are consideredcatastrophic. When such an error has beenreported, the analyzer should be replacedwith a known-good analyzer. The non-functional analyzer should be returned to thefactory for repair. Contact the factory fora Return Materials Authorization (RMA)number.
INSTRUMENT TROUBLESHOOTING
When analyzer is suspected as the problemsource, the analyzer can be evaluated using adecade resistance source or a set ofresistors. These resistor simulate the loadmeasured by the sensor and can be an easy wayto check the operation of the analyzer.
Instrument Electronic Test
Remove the sensor connections from theanalyzer and complete the following steps:
1) Connect the appropriate resistor, based ontemperature sensor configuration, across thetemperature sensor input (i.e., TB2-5 and TB2-6) or configure the analyzer for manualtemperature compensation with a constant 25 Co
temperature.
2) Connect a decade resistance source or theappropriate resistor so that the Green Driveand Red Sense connections are terminated atone end of the resistance source or resistor
I-E67-84-2B March 25, 2002 14-5
and the Black Drive and White Sensorconnections are terminated at the other end.
Note: The analyzer calibration values must be set backto those entered at factory in order for this procedureto be valid. The reset calibration feature resets allcalibration to factory values. Before putting theanalyzer back into service, be sure to perform atemperature, process, and output calibration.
Using the Table 14-2, compare the appliedresistance value against the displayed value.

SENSOR TROUBLESHOOTING
If the sensor is suspected of being the sourceof problems, a quick visual inspection in manycases will identify the problem. If nothingcan be seen, a few electrical tests using adigital multimeter can be performed todetermine if the sensor is at fault. Some ofthese tests can be performed with the sensoreither in or out of the process stream.
Visual Sensor Inspection
Remove the sensor from the process andvisually check the following:
Sensor bodyInspect the sensor body for cracks anddistortions. If any are found, contact ABBfor alternative sensor styles and materials.
Cable and connectors Inspect the sensor cable for cracks, cuts, orshorts. If a junction box and/or extensioncable are used, check for moisture, oil,corrosion, and/or particulates whereconnections are made. All connections must bedry, oil-free, corrosion-free, andparticulate-free. Even slight amounts ofmoisture, corrosion, and particulates can

short sensor signals and affect conductivityreadings. Check to see that all wiring is dryand not shorting against any metal, conduit,or earth grounds. See Section 15,Maintenance, for sensor cleaning procedures.
O-ring sealsInspect the O-ring seals for attack by theprocess liquid. If the O-rings show evidenceof corrosion, distortion, or deterioration,contact ABB for alternate material choices.
Sensor Electronic Test
Conductivity sensors can be electronicallytested to verify the integrity of the sensorand cable. The sensor leads and automatictemperature compensator leads must bedisconnected from the analyzer before anytests can be performed. Additionally, thesetests require a Digital Multimeter (DMM) thathas a conductance function capable of 0 to 200nS and a resistance function capable of 0 to20 kohms.
The automatic temperature compensator can betested with the sensor in the process and istested using the following procedure:
1. Check the resistance of the TemperatureCompensator by measuring the resistancebetween the yellow and blue TemperatureCompensator leads.
For a 3 kohm Balco RTD, the expectedresistance can be calculated using:
where T is in degrees Celsius. The measuredresistance should be within the expected valueby ± 15%.
For a Pt100 RTD, the expected resistance canbe calculated using:

where T is in degrees Celsius. The measuredresistance should be within the expected valueby ± 5%.
For the 4.75 kohm Network, the expectedresistance can be calculated using:
where T is in degrees Celsius. The measuredresistance should be within the expected valueby ± 15%.
Moisture intrusion behind the sensor electrodeseal can be detected with the sensor removedfrom the process, thoroughly dried, and testedusing the following procedure:
1. Check the conductance between the yellowTemperature Compensator lead and each of theother sensor leads (i.e., green, red, white,black, and heavy green leads). The readingmust be less than 0.05 nS.
2. Check the conductance between the greenDrive lead and each of the other sensor leads(i.e., black, white, red, and heavy greenleads). The reading must be less than 0.05nS.
3. Check the conductance between the heavygreen lead (i.e., Shield) and each of theother sensor leads (i.e., blue, yellow, black,green, red, and white leads). The readingmust be less than 0.05 nS.

APPENDIX A - TEMPERATURE COMPENSATION
GENERAL
The TB84EC Advantage Series analyzer has avariety of standard conductivity temperaturecompensation options. These include manual(0.1 N KCl), standard automatic (0.1 N KCl),temperature coefficient (0 to 9.99%/ C), zeroo
to 15 percent sodium hydroxide (NaOH), zero to20 percent sodium chloride (NaCl), zero to 18percent hydrochloric acid (HCl), zero to 20percent sulfuric acid (H SO ), and user-2 4
defined.
Additionally, three specialized types ofautomatic temperature compensation areavailable for the measurement of pure waterusing a Sensor Group C configuration. Thesetypes include neutral salt, trace base, andtrace acid.
The concentration analyzer configurationoffers the same temperature compensationoptions as for the standard conductivityanalyzer configuration.
CONDUCTIVITY AND CONCENTRATION ANALYZER
For these two analyzer types, eleven differenttypes of temperature compensation areavailable. Manual temperature compensation isbased on 0.1 N KCl and has an adjustablereference temperature for Advancedconfiguration. The default referencetemperature for Basic and Advancedconfigurations is 25 degrees Celsius.
Automatic temperature compensation can be setto one of several temperature compensationtypes. When automatic compensation isconfigured, the analyzer will measure theprocess temperature via the resistivetemperature device located either in theconductivity sensor or external to the sensor,and will automatically adjust the rawconductivity to the reference.

The temperature coefficient option allows fora fixed correction which is based on apercentage change of the referenceconductivity (i.e., conductivity at 25 C) pero
degree Celsius. The temperature compensationfactor is derived from the equation:
where:
" and TC.COEF = percentage change in thereference conductivity per degree Celsius.

T = temperature of the solution in degreesCelsius.
Typical ranges for temperature compensationcoefficients are:
C Acids = 1.0 to 1.6%/ C.o
C Bases = 1.8 to 2.0%/ C.o
C Salts = 2.2 to 3.0%/ C.o
C Neutral Water = 2.0%/ C.o
The zero to 15 percent NaOH compensationoption characterizes an average temperaturecorrection required to cover a zero to 15percent NaOH concentration range. Since NaOHhas a relatively constant set of temperaturecoefficients over a large range ofconcentrations, this compensation can be usedfor weak as well as concentrated solutions ofNaOH.

PURE WATER TEMPERATURE COMPENSATION
When using a Sensor Group C configuration,three pure water temperature compensationoptions are available. These include neutralsalt (NEUTRL), trace acid (ACID), and tracebase (BASE). As with all other temperaturecompensation options, the referencetemperature is adjustable with a default valueof 25 degrees Celsius for Advancedconfiguration and is permanently set to 25degrees Celsius.
Temperature compensation for pure water is apolynomial based on data from T.S. Light.This equation compensates for variation inconductivity due to pure water. All threetypes of compensation use this polynomial.For water having a conductivity value greaterthan 0.5 µS/cm, temperature compensation forthe effect of pure water becomes insignificantcompared to the effects brought about by thesolute.

water greater than 0.5 µS/cm will not causeerrors; however, the compensation on soluteeffects (i.e., neutral salt, trace acid, ortrace base) may not accurately adjust foreffects caused by the process liquid.
The polynomial takes the form:

APPENDIX B - CONCENTRATION PROGRAMMING
GENERALThe concentration analyzer configuration hasfour specific solute options and one user-defined option. The specific solute optionsinclude zero to 15 percent NaOH, zero to 20percent NaCl, zero to 18 percent HCl, and zeroto 20 percent H SO . Users needing a custom2 4
concentration configuration can select theuser-defined option which provides a six-point, five-segment linear approximation oftheir own conductivity-to-concentration curve.For the user-defined option, custom units canbe used by either selecting one of threeengineering unit icons or entering a six-character, alphanumeric character string.
USER PROGRAMMED CONCENTRATION TO CONDUCTIVITY CURVES
The TB84EC Advantage Series concentrationanalyzer can be use in any range and with anyABB sensor thus allowing flexible programmingcapability. The user-defined option allowsthe characterization of concentration-to-conductivity curves which have been determinedseparately in a laboratory or from publisheddata such as the International CriticalTables. These curves must then be segmentedinto five straight lines and programmed intothe function generator using the format asillustrated in Figures B-1 through B-5.
Unlike other concentration analyzers, usersmay enter any conductivity and concentrationvalues in an ascending or descending method.Use the following rules when entering data fora Concentration Analyzer configuration:
1. Point 1 for both conductivity andconcentration is always the 0% (i.e., 4mA) output point.
2. Point 6 for both conductivity andconcentration is always the 100% (i.e.,20 mA) output point.
3. All conductivity must be sequentiallyascending. Concentration points can beeither sequentially ascending ordescending.
I-E67-84-2B March 25, 2002 B-2
4. If a reverse acting output is desired,swap the output range values either inthe modify configure state or theoutput/hold mode.
5. The output range (i.e., 4 and 20 mAoutput range) can not exceed the Point 1and Point 6 concentration range; however,the output range can be compressed usingthe rerange (RERNGE) function in theOUT/HOLD mode of operation.
The engineering units are also user-defined.Select either the PPM, PPB, or % icon thatwill be energized in the primary display orenter a six-character, alphanumeric string.This string permanently or temporarily appearsin the secondary display.
For processes with fixed solute types, theuser can select one of the four pre-definedsolute options. These options include zero to15 percent NaOH, zero to 20 percent NaCl, zeroto 18 percent HCl, and zero to 20% H SO .2 4
For reference purposes, the followinginformation is provide on these fourpreprogrammed options. This information hasbeen compile and extrapolated from theInternational Critical Table. All data andcurves are referenced at 25 C. Thiso
information has been curve-fitted to simpleequations for use in the TB84EC and onlyapproximates the actual concentration curves.If improved accuracy is required, especiallyin a narrow region of concentration, it issuggested that the user-defined option isselected and data be manually entered.
