Safety Summary

GENERALWARNINGS

Equipment EnvironmentAll components, whether in transportation, operation or storage,must be in a noncorrosive environment.

Electrical Shock Hazard During MaintenanceDisconnect power or take precautions to insure that contact withenergized parts is avoided when servicing.

SPECIFICCAUTIONS

To prevent possible signal degradation, separate metal conduitruns are recommended for the sensor, signal and power wiring.

Automatic Nernstian With Solution Coefficient compensation canonly be used for processes that are extremely repeatable.

I-E67-84-1B February,2002 1-1

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 1 - INTRODUCTION

OVERVIEWThe TB84PH Advantage Series is a line-poweredpH/ORP/pION (i.e., specific ion) analyzer withstate-of-the-art electronics, internal andexternal diagnostic functionality, aninnovative user-interface having HotKeycapability, two user-selectable modes ofoperation, and DIN-size packaging.

Diagnostic interrogation of the internalcircuitry and external sensing devices iscontinually conducted to ensure accuracy andimmediate notification of problem situationswhen they occur. Detection of sensorintegrity includes pH electrode damage, sensorcoating, sensor out-of-liquid, ground-loopdetection, and short/open sensor cabling.Additional software functions monitor slope,asymmetric potential, process variableover/under range, and temperature over/underrange. If these diagnostic conditions occur,the analyzer can be programmed to induce arepetitive modulation of a given magnitude inthe output current or can be link to a relayoutput thus providing the ability to alertpersonnel of a problem condition.

The analyzer packaging conforms to DINstandards and has mounting options thatinclude pipe, wall, hinge, and panelinstallations. Due to the modular design ofthe electronics, changing the analyzer sensingcapability to other analytical properties suchas solution conductivity can be quick andeasy.

The user interface is an innovative, patent-pending technology which facilitates a smoothand problem-free link between the user andanalyzer functionality. The programmingstructure and multi-function keys reduceprogramming difficulties by providing a togglebetween Basic and Advanced functions.

SECTION 2 - ANALYZER FUNCTIONALITY ANDOPERATOR INTERFACE CONTROLS

INTRODUCTION

The beginning of this section contains anoverview of the TB84PH pH/ORP/pION AdvantageSeries analyzer functionality and importantinformation for configuration personnel. Thelatter part of this section discusses theoperator interface controls. It includesdescriptions of the analyzer modes andfaceplate controls.

ANALYZER OVERVIEW

The TB84PH Advantage Series analyzer providestwo analog output signals that can beconfigured to be proportional to either theoutput of any electrochemical sensor having aDC voltage output between -2000 and +2000 mVand/or a 3k Balco or Pt100 RTD. This includessensors requiring electrometer type detectorssuch as pH, ORP, and specific ion (i.e., pION)sensors. In addition to the two analogoutputs, any of the three integral relayoutputs can be configured as a high or lowsetpoint controller, cycle-timer controller,diagnostic alarm, or cleaner controller. Inthis manner, the TB84PH Advantage Seriesanalyzer provides a means by which to monitorand control the pH, ORP, pION, or IonConcentration 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 pH glasselectrode impedance, reference electrodeimpedance, ground-loop detection, open andshorted cabling, process variables out ofrange, and incorrect calibration values.

I-E67-84-1B February,2002 2-2

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.

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 TB84PH 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 anoperational one.

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 TB84PH 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-E67-84-1B February,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 insuresatisfactory 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-E67-84-1B February,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. Twisted,shielded pairs should be used for the bestresults.

The mounting location should provide easyaccess for maintenance procedures and not bein a corrosive environment. Excessivemechanical vibrations and shocks as well asrelay and power switches should not be in theimmediate area. Additionally, this locationmust conform to the temperature and humidityconstraints listed in the Table 1-3,Specifications.

HAZARDOUS LOCATIONS

WARNING Use this equipment only in those classes ofhazardous locations listed on the nameplate.Installations in hazardous locations otherthan those listed on the nameplate can leadto unsafe conditions that can injurepersonnel and damage equipment.

Refer to Table 1-3, Specifications, in Section1 for a list of certifications and approvalsapplicable to the TB84PH Advantage Seriesanalyzer.

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 ashort length of flexible conduit should beinstalled to reduce any stress to the housing.

Note: To maintain a NEMA 4X/IP65 rating, use approvedconduct 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 Inc.. See Section 17, Support Services.

The TB84PH 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.

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 TB84PH 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.

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:


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.

Advantage Series (TBX5) Sensor WiringInstrument connections for the sensor wiringare located next to the signal connections.Sensor wiring should be run in shieldedconduit, or similar, for protection fromenvironmental influences. Do not allow thewires to become wet. The wiring should notlay on the ground or over any other equipment.Ensure cables are not abraded, pinched or bentduring the installation process or duringnormal operation.

The sensor cable has seven leads with pinterminals that must be connected to theterminal block in the rear cavity of theTB84PH Advantage Series analyzer. The sevenleads are color coded and have the followingfunctions and connections:

Figure 3-7. Instrument Wiring Diagram.Non-Advantage Series (TB5) Sensor Wiring

For standard and Next Step ABB sensors (i.e.,TB5), a pin terminal option is available forinstallation to a TB84PH Advantage Seriesanalyzer. Though this cable option isrecommended when using a non-Advantage Seriessensor, stocking preferences may tend towardsthe use of one common sensor. If this sensortype requires a BNC connector to mate withexisting instrumentation, a BNC Adapter(included with all TB84PH Advantage Seriesanalyzers) provides such a connection.

When using the pin terminal sensor cableoption (i.e., the T[][] nomenclature optionwhere [][] represents the cable length),connect color coded leads to the analyzer’sterminal block as follows:

Note: Red and White conductors will only be present if*

a temperature compensator is being using.

Since pH/ORP/pION sensor cables generallycontain a low-noise conductive layer withinthe coax, complete removal of this layer isextremely important to ensure correct sensoroperation. Additionally, most conductorswithin the sensor cable are small and are notrecommended to be used directly in the TB84PHAdvantage Series’ terminal blocks; therefore,the BNC Adapter (p/n 4TB9515-0164 or 4TB9515-0166) is recommended over removing the BNC andstripping back each of the individualconductors.

Using Figure 3-8 as a reference, install theBNC Adapter and connect the BNC-type sensor asfollows:

1) Remove the earth ground screw and hardwarelocated below the SENSOR CONNECTIONS terminalblock.

2) Slide the earth ground screw (and remaininghardware if desired) through the screw hole onthe BNC Adapter so that the adapter’s leadsand female BNC are pointing upwards.

3) Mount the BNC Adapter to the availablethreaded earth ground hole.

I-E67-84-1B February,2002 3-16

4) Connect the BNC Adapter pin terminals tothe corresponding SENSOR CONNECTIONS terminalblock locations via the conductor colorcoding.

Note: If the sensor does not have a femaleconnector for the Temperature Compensator(TC), connect the leads from the sensordirectly to the terminal block locations TB2-5and TB2-6 (i.e., Red and White). For sensorswithout TC, leave TB2-5 and TB2-6 open.

Figure 3-8. BNC Adapter Installation and Wiring Diagram

5) Connect the male BNC from the sensor to thefemale BNC from the BNC Adapter and the femaleTC connector from the sensor to the male TCconnector from the BNC Adapter.

6) Slide the protective boot over the BNCconnection to prevent any possible shorting toearth surfaces.

Note, if the BNC surface is in contact with aearth ground surface, a ground loop throughthe sensor may occur and could result in poorsensor performance and shortened sensor life.

I-E67-84-1B February,2002 3-17

GROUNDING

The customer and/or wiring contractor isresponsible to ensure that the analyzer,associated control or test equipment, and allexposed conductive materials are properlygrounded. Grounding procedures should be inaccordance with local regulations such as theNational Electrical Code (NEC), CanadianElectrical Code (CEC), or equivalent.Equipment installation 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.

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 does 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.

OTHER EQUIPMENT INTERFACE

The TB84PH Advantage Series analyzer providestwo isolated current outputs that areproportional to the process variable(s).Since the analyzer output is isolated, eachcurrent loop may have a maximum of one non-isolated device within its circuit.

SECTION 4 - OPERATING PROCEDURES

INTRODUCTION

The TB84PH Advantage Series analyzer has sevenmain operating modes: Measure, Calibration,Output/Hold, Configuration, Security,secondary Display, and Setpoint/Tune. Withineach mode, several programming statescontaining functions specific to the relatedmode are available.

The TB84PH 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. Each icon represent a key functionthat is energized when that function isrequired (patent-pending).

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 TB84PH 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 using the FAULT INFO keywhen the instrument is in the Measure Mode ofOperation.

OPERATOR INTERFACE CONTROLS REVIEW

Liquid Crystal Display (LCD)

The LCD contains nine regions that provide theuser with information on the process variable,engineering units, mode of operation, outputhold condition, fault indication, relayactivation, secondary variable, and keyfunction assignments. Figure 4-1 shows afully energized LCD, Smart Keys, and modetext.

Figure 4-1. Fully Energized Display AndSupporting Information.The top set of icons informs the user of anabnormal operating condition such as a outputHOLD condition, FAULT condition, diagnosticSPIKE output, or RELAY activation. Theseicons are only energized when such a conditionis detected and are active in all modes ofoperation.

For the mode of operation indicators (shown asright arrows grouped next to the mode text),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.

The process variable is displayed in the threeand one-half digit, seven segment region.

I-E67-84-1B February,2002 4-3

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 textualprompting in all other modes of operation.Due to the limited number of characters forthis display region, much of the promptingtakes the form of text abbreviations (seeAppendix B for a list of abbreviations.) Thisregion is active 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 KeysA five-button, tactile keypad is located onthe front panel of the instrument. Four ofthe gray buttons are embossed to easily showtheir location. A fifth, hidden buttonlocated at the top of the NT in the textADVANTAGE has been included to provide accessto functions that are infrequently 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, icons are energized over the key toindicate its function. If a Smart Key doesnot have an icon energized above its location,this Smart Key does not have a function andwill not initiate an action when pressed.Using this Smart Key method, a smaller numberof keys can be used without complicatinginstrument functionality.Table 4-1.

MODES OF OPERATION

The Measure Mode is the normal operating modeof the TB84PH 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 analyzeranalog outputs, for example,during maintenance.

Configure Used to configure analyzerfunctions such as temperaturecompensation, temperaturesensor type, and measurementelectrode type.

Security Used to enter passwordprotection for the Calibrate,Out/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.

I-E67-84-1B February,2002 4-6

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.

Automatic activation occurs during a Two-PointProcess Variable Calibration and Cleaneractivation. For the Two-Point ProcessVariable Calibration, the analyzer willautomatically hold all outputs at the currentlevels and states. Upon completing the two-point calibration, the TB84PH Advantage Seriesanalyzer will query the user to either releaseor maintain the hold condition.

For a relay output configured as a Cleaner, auser has the option to enable an automatichold condition using the levels and statescapture directly before initiating thecleaning operation. The hold condition onlyoccurs during the relay on and recovery timesand can be separately set for the analog andrelay outputs. If desired, the relay outputscan be disabled instead of held during acleaning cycle.

I-E67-84-1B February,2002 4-7

FAULT ICON

The Fault icon energizes when a faultcondition has been detected by the TB84PHAdvantage Series analyzer. Fault conditionsinclude all problem and error detection asoutlined in Section 13, Diagnostics.

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 TB84PH 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 thespecified relay (i.e., Relay One, Relay Two,and Relay Three.) When a relay change statefrom its normal state to an energize state,the corresponding Relay icon also energizes.Since the normal state of each relay can beset by a switch, the relay icon will onlyinform the user of a state change and notwhether the relay has closed or opened.

I-E67-84-1B February,2002 4-8

I-E67-84-1B February,2002 5-2

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),reference impedance in kohms, sensor output inmillivolts (i.e., mV), and firmware revision.See Section 10, Secondary Display, for moreinformation.

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.

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 the

I-E67-84-1B February,2002 5-3

displayed mode of operation is achieved byusing the SELECT Smart Key. An escapefunction to the Measure Mode of Operation isprovided using 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.

Since each mode of operation contains manyoperation states used to set or tune theTB84PH Advantage Series analyzer functions,the following sections of this productinstruction manual contain detaileddescriptions of each mode of operation.Screen flow diagrams showing the programmingtext prompts, Smart Key assignment, and theresulting action for each Smart Key are alsoincluded.

SECTION 6 - CALIBRATE MODE

INTRODUCTION

The Calibrate Mode of Operation provides theability to calibrate the sensor input,temperature input, and analyzer outputs.These functions (i.e., Calibrate States ofOperation) include process variable,temperature, edit, reset, and outputcalibration.

CALIBRATE STATES OF OPERATIONThe Calibrate Mode consists of six states ofoperation. Table 6-1 describes the functionof each state of operation.

I-E67-84-1B February,2002 6-4

One-Point Calibrate State

Due to variations in ionic strength betweenthe sensor reference and process liquid,improved accuracy can be realized byconducting a one-point calibration with thesensor in its final location. Typically, theanalyzer is verified against an externalvalidation device using a grab sample. TheOne-Point Calibrate State conducts an offsetadjustment on the sensor input.

Conduct a One-Point Calibration using Figure6-2 as a reference and the followingprocedure:

1) Select the 1PT.CAL in the Process SensorCalibrate State of Operation using theSELECT Key.

2) Verify the process variable value usingan external instrument having the sametype of temperature compensation and agrab sample.

3) Confirm the TB84PH Advantage Seriesanalyzer displayed reading is STABL?(i.e., stable) using either the YES or NOKey. If the NO Key is pressed, theanalyzer will return to the ProcessSensor Calibrate State. For an unstablecondition, conduct one or more of thefollowing steps:

a) Wait until process liquidcomposition stabilizes,

b) Check to see if the TB84Advantage 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 14, Troubleshooting.

I-E67-84-1B February,2002 6-5

4) If the reading was stable, 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., CurrentTB84PH Indication + [Grab Sample Value -TB84PH Indication at the time the grabsample was taken]). Use the Key toincrement the digit value and the Keyto move to the next digit. Press theENTER Key to enter the new value.

Invalid calibration values will generate thetext string BAD.CAL, and the calibration valuewill not be accepted. If the new value isvalid, the Efficiency (i.e., slope value shownas a percentage of theoretical) will be shown.Pressing the NEXT Smart Key displays theOffset value. At this point, the user canreturn to the Process Sensor Calibrate Stateby pressing the NEXT Smart Key or to theMeasure Mode by pressing the Exit To MEASURESmart Key.

Note: If a Hold condition is present, the TB84PHAdvantage Series analyzer inquires if thiscondition should be released.

For more information on sensor calibrationtechniques and troubleshooting, refer to TP90-2.

Two-Point Calibrate StateThe Two-Point Calibrate State conducts offsetand slope adjustments on the sensor input todetermine its response characteristics. Thiscalibration is typically conducted beforeinstallation into its final location andperiodically during the life of the sensorwhen the response of the sensor begins todecrease. This calibration procedure usesbuffers or standards depending on the type ofsensor (e.g., pH versus pION, respectively).

When conducting a Two-Point Calibration, theTB84PH Advantage Series analyzer initiates anautomatic Hold All condition. The Hold iconwill begin to flash, and the Hold Allcondition will remain active until thecalibration is complete.

At this point, the user canreturn to the Process Sensor Calibrate Stateby pressing the NEXT Smart Key or to theMeasure Mode by pressing the Exit To MEASURESmart Key.

Note: If a Hold condition is present, the TB84PHAdvantage Series analyzer inquires if thiscondition should be released.

For more information on sensor calibrationtechniques and troubleshooting, refer to TP90-2.

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 TB84PHo

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 the ResetCalibration procedure.

SECTION 7 - OUTPUT/HOLD MODE

INTRODUCTION

The Output/Hold Mode of Operation provides theability to set the outputs to fixed levelsand/or states, change the output ranges, dampthe output signals, or disable the diagnosticspike.

OUTPUT/HOLD STATES OF OPERATION

The Output/Hold Mode consists of six states ofoperation. Table 7-1 describes the functionof each state of operation.

Table 7-1. Output/Hold States

State Function

HOLD Used to fix output levels and/orstates to values captured whenthe hold was initiated or tomanually entered values, or usedto release an existing outputHOLD state.

AO1.RNG Used to change Analog Output Onerange.

AO2.RNG Used to change Analog Output Tworange.

DAMPNG Used to reduce fluctuation inthe displayed values and/oroutput signals.

SPIKE Used to enable or disable thespike output function ifconfigured.

In the Output/Hold Mode, the NEXT Smart Keysequentially moves the user to all otherOutput/Hold States. The cycle repeats untilan Output/Hold State is selected using theSELECT Smart Key or the escape function ischosen using the Exit To MEASURE Smart Key.Use Figure 7-1 to identify Smart Keyassignments and the resulting action.

5) For held relay outputs, toggle the relayto the desired state (i.e., OFF or ON)using the Key, and press the ENTER Keyto enter the new value. Press the Exit ToMEASURE Key to escape to the MeasureMode.

Note: If the YES key was used to commission ahold condition on any output, initiating theescape function will not affect the commissionedHold condition. To release this Hold condition,the Hold State must be re-enter and the Holdcondition released either by using the YES Keywhen requested to release all holdconditions(i.e., REL.HLD) or by removing thehold condition using the NO Key whenindividually setting each output.

If a hold condition(s) already exists and theuser selects the Hold State of Operation, theTB84PH 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 StateThe 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.

Conduct a Rerange of the output values usingthe following procedure:

1) Select the Rerange State of Operationusing the SELECT Key.

2) Edit the process variable value for thezero or four milliampere point

I-E67-84-1B February,2002 7-7

(determined by the analyzer’sconfiguration) 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, orpress the ENTER Key to continue to the 20milliampere value. Press the Exit ToMEASURE Key to escape to the MeasureMode.

3) Press the ENTER or Exit To MEASURE Key toescape to the Measure Mode, or edit theprocess 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 new value.

Note: If 1)the zero or four milliampere value ischanged, 2)the new value is valid per thespecification in Table 1-3, 3)this change isaccepted using the Enter Key, and 4)the userescapes to the Measure Mode using the Exit ToMeasure Key without adjusting the 20 milliamperevalue, the output range will now reflect thenewly entered zero or four milliampere point.

Analog Output Two Rerange State

The Analog Output Two Rerange Output/HoldState provides the ability to change theoutput range of Analog Output Two. One orboth end point values can be changed to anyvalue or range of values that are within thespecifications listed in Table 1-3.

Conduct a Rerange of the output values usingthe following procedure:

1) Select the Rerange State of Operationusing the SELECT Key.

I-E67-84-1B February,2002 7-8

2) Edit the process variable value for thezero or four milliampere point(determined by the analyzer’sconfiguration) 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, orpress the ENTER Key to continue to the 20milliampere value. Press the Exit ToMEASURE Key to escape to the MeasureMode.

3) Press the ENTER or Exit To MEASURE Key toescape to the Measure Mode, or edit theprocess 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 new value.

Note: If 1)the zero or four milliampere value ischanged, 2)the new value is valid per thespecification in Table 1-3, 3)this change isaccepted using the Enter Key, and 4)the userescapes to the Measure Mode using the Exit ToMeasure Key without adjusting the 20 milliamperevalue, the output range will now reflect thenewly entered zero or four milliampere point.

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 value can be set from 0.0to 99.9 seconds and represents 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.)

Note: Once the Spike State is OFF, changing theconfigured spike level in the Configure Modewill not re-enable the Spike State. The SpikeState can only be turned ON or OFF in theOutput/Hold Mode of Operation.

I-E67-84-1B February,2002 8-1

SECTION 8 - CONFIGURE MODE

INTRODUCTION

The Configure Mode of Operation establishesthe operating parameters of the TB84PHAdvantage 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 TB84PH Advantage Seriesanalyzer.

PRECONFIGURATION DATA REQUIRED

Before attempting to configure the TB84PHAdvantage Series analyzer, the followingrequirements must be defined.

1. Analyzer parameters.

Figure 8-1. Screen Flow Diagram ForModify/View and Basic/Advanced ConfigureStates of Operation.As seen in Figure 8-1, the TB84PH 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.

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 by

I-E67-84-1B February,2002 8-3

pressing 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 TB84PH 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.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 TB84PH 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.

I-E67-84-1B February,2002 8-4

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 TB84PH Advantage Seriesanalyzer. Upon receipt of the analyzer, thedefault configuration (unless otherwisespecified by the customer when ordering theTB84PH 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 sensor interface,output parameters, and diagnosticfunctionality. Table 8-1 describes each ofthese programming modes and their function.

Analyzer State (Basic/Advanced)

The Analyzer State sets the type ofmeasurement (i.e., process variable) and mustcoincide with the type of sensor being used.Table 8-2 describes the function andprogramming mode of each state.

Table 8-2. Analyzer States

I-E67-84-1B February,2002 8-8


PH Used to measure the pH of a solution. Basic/AdvancedProcess variable engineering units arepH.

ORP Used to measure the Oxidation Reduction Basic/AdvancedPotential (ORP) of a solution. Processvariable engineering units aremilliVolts (mV).

PION Used to measure the concentration of a Basic/Advancedspecific ion in a solution. The sensormust use a measurement electrodespecific to the ion of interest.Process variable engineering units aremilliVolts (mV).

ION.CON Used to measure the concentration of a Advancedspecific ion in a solution. The sensormust use a measurement electrodespecific to the ion of interest.Process variable engineering units areset by the user, and the output isdirectly proportional to those unitsand is established by the number ofconcentration decades.

pH Analyzer State (Basic/Advanced)

The pH Analyzer State contains three types ofsensors: Glass, Antimony, and Custom. Table8-3 describes the function and programmingmode of each state.

Table 8-3. pH Analyzer States


PH.GLAS Used when the associated sensor has a Basic/Advancedstandard glass measuring electrode.

ANTMNY Used when the associated sensor has an Basic/Advancedantimony measuring electrode.

CUSTOM Used when the associated sensor has a Advancedmeasuring electrode with a uniqueisopotential point and asymmetricpotential.

For Advanced configurations using the PH.GLASand ANTMNY Analyzer States, the REF Z (i.e.,reference impedance) value can be manually setto a new value or left at the default value of100 kohms. The REF Z is the referenceelectrode impedance value that will trigger adiagnostic condition. This value is set using

I-E67-84-1B February,2002 8-9

the Smart Key to increment and the SmartKey to move. The ENTER Smart Key accepts thenew value. See Section 13, Diagnostics, formore information on diagnostic reporting.

The reference impedance of a new ABB sensor istypically 1 to 2 kohms as measured by thediagnostic circuit of the TB84PH AdvantageSeries analyzer. Performance of the referenceelectrode is typically unaffected up to 100kohms (i.e., the default REF Z value).Adjustment to other resistance values up to1000 kohms is allowed; however, acceptableperformance of the sensor must be determinedby the user and the resistance valuesaccordantly adjusted.

For the CUSTOM State, the ISO.PT (i.e.,Isopotential pH value) and ASY.POT (i.e.,Asymmetric Potential value) must be enteredusing the Smart Key to increment theblinking digit, the Smart Key to move tothe next digit, and the ENTER Smart Key toenter the new value. The REF Z value can alsobe adjusted and must be set as previouslydescribed.

ORP and pION States (Basic/Advanced)

The ORP or pION Analyzer States are set bypressing the ENTER Smart Key on the desiredstate when displayed using the NEXT Smart Key.For Advanced configurations, the ORP and pIONStates will require the user to enter the REFZ value. The REF Z (i.e., referenceimpedance) is the reference electrodeimpedance value that will trigger a diagnosticcondition.

The REF Z value is set using the Smart Keyto increment the blinking digit, the SmartKey to move to the next digit, and the ENTERSmart Key to enter the new value. See Section13, Diagnostics, for more information ondiagnostic reporting.

Ion Concentration State (Advanced)

The ION.CON (i.e., Ion Concentration) Stateallows for pION sensor inputs to be convertedto concentration units such as ppb and ppm.This state uses temperature compensated mVvalues and applies a logarithmic function thathas a fixed end point in millivolts, an ionvalence ranging from -3 to +3, and an endpoint magnitude which can be set to 10, 100,or 1000.

The ION.CON State functions by associating anend millivolt value to an end magnitude value.The valence determines the millivolt changeper decade of concentration and is defined bythe Nernst Equation (i.e., 59.16 mV/decade fora valence equal to 1, 29.58 mV/decade for avalence equal to 2, and 19.72 mV/decade for avalence equal to 3). If the valence isnegative the millivolt/concentrationrelationship will have a negative slope. Thenumber of magnitudes defines the analyzeroutput. For example, two magnitudes would setthe output to 0-10% for the first magnitudeand 10-100% for the second magnitude.

Configure an ION.CON Analyzer State usingFigure 8-4 as a reference and the followingprocedure:

1) Enter the ION.CON State using the ENTERKey.

Temperature Sensor State (Basic/Advanced)The Temperature Sensor State configures thetemperature input for a Pt100, 3 kohm Balco,or no (i.e., NONE) RTD.

Set the Temperature Sensor State using thefollowing procedure.

1) Select the TMP.SNS State using the SELECTKey.

2) Choose the desired temperature sensor byusing the NEXT Key to toggle betweenNONE, 3K.BLCO (i.e., 3 kohm Balco), andPT100, and enter the temperature sensorby using the ENTER Key when the correctsensor is displayed in the secondarydisplay.

Temperature Compensation State (Basic/Advanced)

Temperature affects the process variable intwo ways. The first effect (i.e., NernstianEffect) causes the sensor output to increasewith increasing temperature. In the case of apH sensor, the increase is roughly 0.03 pH/pHUnit From 7pH/10 C. Since ABB pH sensors useo

Silver/Silver Chloride Measurement andReference Half Cells, the isopotential point(i.e., the pH value that is unaffected bytemperature) of these sensors is 7 pH.

The second temperature effect is on the actualchemistry of the solution. Since iondisassociation can be a function oftemperature, ion properties such as pH, ORP,and pION are affected by changes in processtemperature. These effects can be empiricallydetermined and included in the temperaturecompensation process using the AutomaticNernstian with Solution CoefficientTemperature Compensation option.

The Temperature Compensation State sets thedesired compensating method. The three statesof temperature compensation include ManualNernstian, Automatic Nernstian, and AutomaticNernstian with Solution Coefficient. Table 8-

I-E67-84-1B February,2002 8-13

4 describes the function and programming modeof each state.

Table 8-4. Temperature Compensation States


MANUAL Used when a fixed temperature value Basic/Advancedcan be applied instead of a measuredvalue. The initial value is set at25 C. Use the Temperature Calibrateo

State to change the fixed temperaturevalue. Nernstian compensation isapplied using the fixed temperaturevalue.

AUT.SOL Used when a measured temperature value Advancedis being provided by a temperaturesensor. Nernstian compensation and asolution coefficient is applied usingthe measured value.

Manual Nernstian State (Basic/Advanced)

Manual temperature compensation adjusts fortemperature effects of the sensor at aspecific temperature. A temperature sensor isnot required (i.e., NONE for TMP.SNS). TheManual Nernstian State is only applicable forpH Analyzer States. The displayed processvariable (i.e., pH) is standardized to 25 C.o

I-E67-84-1B February,2002 8-14

When using the Manual Nernstian State, theprocess temperature will be automatically setto 25 C. To adjust the temperature to othero

values, use the Temperature Calibrate Stateand set the temperature to the new value asspecified in Section 6, Calibrate Mode. Theallowable solution temperature range is 0 to140 C.o

1) Select the TC.TYPE State using the SelectKey.

2) Move to the MANUAL Nernstian State usingthe Next Key.

3) Set the TC.TYPE to MANUAL using the EnterKey.

Automatic Nernstian State (Basic/Advanced)

Automatic Nernstian temperature compensationrequires an input from a temperature sensingdevice. The input can be either from a Pt100or 3 kohm Balco RTD.

Automatic Nernstian temperature compensationcorrects for temperature effects caused bysensor and is only applicable for the pHAnalyzer State. The displayed processvariable (i.e., pH) is standardized to 25 C,o

and the allowable solution temperature rangeis 0 to 140 C.o

4) Set the PH/10C or MV/10C value (as thecase may be) using the Key toincrement the blinking digit and the Key to move to the next digit andpressing the ENTER Key to enter the newvalue.

Analog Output One State (Basic/Advanced)The Analog Output One State sets the outputspan, range, and function. The output span issoftware selectable for either zero to 20milliamperes or four to 20 milliamperes and issource to the Primary Process Variable. ForBasic configurations, the output function canonly be linear. Lower and upper range valuesmust be entered and are defaulted to the fullscale process variable range (e.g., 0-14 pHfor pH Analyzer States). For Advancedconfigurations, the output function can belinear or non-linear. For a non-linearoutput, lower and upper range values must alsobe entered as well as five break points.

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 (e.g., 0-14 pH).

For a reverse acting output, reverse the zeroor four and 20 milliampere values (e.g., 14 pHfor the zero or four milliampere value and 0pH for the 20 milliampere 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 14 or -1999 to +1999 mV) andthe break points 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.

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 andmust be entered as percentage of input rangeand output span. Also as with a linearoutput, a reverse acting non-linear output canbe implemented by reversing the zero or fourand 20 milliampere process variable and breakpoint values (e.g., 1999 mV for the 4milliampere value and -1999 mV for the 20milliampere value).

Setpoint Relay Output (Basic/Advanced)

A Setpoint Relay Output can be configured toenergize when the Process Variable orTemperature exceeds (i.e., a High Setpoint) orfalls below (i.e., a Low Setpoint) a definedlevel. Valid Setpoint values are limited tothe Process Variable and/or Temperature rangeof the TB84PH Advantage Series analyzer. SeeTable 1-3, Specifications, for analyzer rangevalues.

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 0.00 to 10.00 pH forpH, 0 to 200 mV for ORP and pION, 0 to 10% ofthe END.MAG (i.e., End Magnitude) for IonConcentration Process Variable sources and 0to 10 C (18 F) for Temperature sources.o o

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 (i.e., LO SPT or HI SPT)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 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.

Damping State (Basic/Advanced)

The Damping State applies a lag function onthe configured signals and reducesfluctuations caused by erratic processconditions. The damping value can be set from0.0 to 99.9 seconds and represents the timerequired to reach 63.2% of a step change inthe process variable.

For the Basic Programming Mode, the dampingvalue can only be applied to the processvariable input signal. The AdvancedProgramming Mode allows for separate dampingof the Display Process Variable, Analog OutputOne, and Analog Output Two.

Set the Damping State using Figure 8-15 as areference and the following procedure:

1) Select the DAMPNG State using the SELECTKey.

(i.e., AO2.SEC) 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.

Diagnostics State (Basic/Advanced)

The Diagnostics State allows the built-insensor diagnostics to be disabled. When asensor does not have a solution ground such asNon-Advantage (i.e., TB5) sensors, thediagnostic signal cannot be injected intoprocess liquid. For these situations andapplications that use very pure water, thesensor diagnostics should be disabled.

Set the DIAG (i.e., Diagnostics) State usingthe following procedure:

1) Select the DIAG State using the SELECTKey.

2) Toggle the diagnostics function to thedesired state (i.e., OFF or ON) using the Key, and press the ENTER Key to enter

the new value.

Safe Mode One State (Basic/Advanced)

The Safe Mode One State determines the AnalogOutput One level if an error condition occursthat renders the analyzer inoperable. Theavailable states are FAIL.LO (i.e., fail low)or FAIL.HI (i.e., fail high). For moreinformation on error conditions, see Section13, Diagnostics.

Set the Safe Mode One State using thefollowing procedure:

1) Select the SAF.MD.1 State using theSELECT Key.

2) Set the safe mode by using the NEXT Keyto toggle between FAIL.LO and FAIL.HI,and use the ENTER Key to enter the newvalue.

Safe Mode Two State (Basic/Advanced)

The Safe Mode Two State determines the AnalogOutput Two level if an error condition occursthat renders the analyzer inoperable. Theavailable states are FAIL.LO (i.e., fail low)and FAIL.HI (i.e., fail high). For moreinformation on error conditions, see Section

I-E67-84-1B February,2002 8-36

13, Diagnostics.

Set the Safe Mode Two State using thefollowing procedure:

1) Select the SAF.MD.2 State using theSELECT Key.

2) Set the safe mode by using the NEXT Keyto toggle between FAIL.LO and FAIL.HI,and use the ENTER Key to enter the newvalue.

Spike State (Advanced)

The Spike State sets the diagnostic spikelevel as a percent of output. This level willdetermine the magnitude of the spike.

When the Spike has been set for any levelgreater than 0% and is enabled in the SpikeOutput State, the TB84PH Advantage Seriesanalyzer will modulate the Analog Output Onesignal by the configured level for one secondout of every six seconds when a problemcondition is detected. Using this modulation,the analyzer informs the operator of adetected diagnostic condition. For moreinformation on problem conditions, see Section13, Diagnostics. For a description of thediagnostic spike feature, see Section 2,Analyzer Functionality And Operator InterfaceControls.

Set the Spike State using the followingprocedure:

1) Select the SPIKE State using the SELECTKey.

2) Set the SPK.MAG (i.e., spike magnitude)using the Key to increment theblinking digit and the Key to move tothe next digit, and press the ENTER Keyto enter the new value. 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, changing theconfigured spike level in the Configure Modewill not reenable the Spike State. The SpikeState can only be turned ON or OFF in the

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 change relay parameterspertinent to process control. To change therelay output function, see Section 8,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 (i.e., a High Setpoint) orfalls below (i.e., a Low Setpoint) a definedlevel. Valid Setpoint values are limited tothe Process Variable and/or Temperature rangeof the TB84PH Advantage Series analyzer. SeeTable 1-3, Specifications, for analyzer rangevalues.

I-E67-84-1B February,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 0.00 to 10.00 pH forpH, 0 to 200 mV for ORP and pION, 0 to 10% ofthe END.MAG (i.e., End Magnitude) for IonConcentration Process Variable sources and 0to 10 C (18 F) for Temperature sources.o o

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 a reference and thefollowing procedure:


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 TB84PH AdvantageSeries analyzer. See Table 1-3,Specifications, for analyzer range values.Valid Cycle Time and On Time values are 0.0 to99.9 minutes.

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.


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-E67-84-1B February,2002 11-7

Set the Cleaner parameters of a Relay Outputusing Figure 8-14 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.


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.

4) Hold the Analog Outputs (i.e., AO.HLD)during the On and Recovery Times usingthe YES Key, or leave the Analog Outputslive during the On and Recovery Timesusing the No Key.

5) Hold the Relay Outputs (i.e., RO.HLD)during the On and Recovery Times usingthe YES Key, or continue onto the DisableRelay Outputs State during the On andRecovery Times using the No Key.

SECTION 13 - DIAGNOSTICS

INTRODUCTIONThe TB84PH Advantage Series analyzer performsa number of diagnostic checks on hardware,software, 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 TB84PH 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.

Problem CodesProblem Codes result from fault conditionsthat impact the performance of the TB84PHAdvantage Series analyzer. In most cases,these conditions can be resolved by the userusing standard practices.

I-E67-84-1B February,2002 13-2

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 TB84PH 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 TB84PH Advantage Series analyzerinoperable. In most cases, these conditionscan not be resolved by the user using standardmethods.

The occurrence of an Error Code fault

I-E67-84-1B February,2002 13-4

condition 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.

Table 13-3 contains all the Error Codessupported by the TB84PH Advantage Seriesanalyzer. Each entry lists the Error Codenumber, displayed text string, and a shortdescription of the fault condition. SeeSection 14, Troubleshooting, for resolving afault condition.

Calibration Diagnostic Messages

The TB84PH Advantage Series analyzer performsautomatic efficiency and offset calculationsrelative to a theoretically perfectelectrochemical and/or temperature sensorduring each calibration cycle. Calibrationhistory is retained for future interrogationusing the Edit Calibrate State. Thecalibration constants that are displayed areEfficiency and Offset for the Process Variableand Slope and Offset for the Temperature.

An Efficiency of less than 60% or greater than110% indicates a potentially bad processcalibration point or poor performing sensor.Calibration values that yield Efficiencyvalues less than 40% or greater than 150% arenot accepted. In these cases, the text stringBAD.CAL (i.e., bad calibration) is displayedin the secondary display region. The user isreturned to the beginning of the calibrationcycle after the bad calibration has beenreported.

I-E67-84-1B February,2002 13-5

An Offset value of less than -180.0 mV orgreater than +180 mV also indicates apotentially bad process calibration or poorperforming sensor. Calibration values thatyield Offset values less than -1000 mV orgreater than +1000 mV are not accepted.Again, a bad calibration will be reported, andthe user returned to the beginning of thecalibration cycle.

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.o o

Temperature calibrations use smart softwareroutines that automatically adjust the Slope,Offset, or both values based on thecalibration value being entered andcalibration history if it exists.

I-E67-84-1B February,2002 13-6

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.

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 and

I-E67-84-1B February,2002 14-6

visually 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. Allconnections must be dry, oil-free, corrosion-free, and particulate-free. Even slightamounts of moisture, skin oils, corrosion, andparticulates can short sensor signals due tothe high impedance of these signals. If a BNCconnector is used, check to see that it is dryand not shorting against any metal, earthgrounds, or conduit.

Measuring electrodeInspect the glass electrode for breaks orcracks. If breakage is a problem, contact ABBfor alternative electrode choices orsuggestions regarding alternate sensormounting locations.

Inspect the measurement electrode for foulantsor scales. Many scales are not noticeablewhen the sensor is wet. Using a tissue, drythe glass electrode and hold it up to a brightlight. Scaling will appear as a whitish,textured material on the surface of theelectrode. Films will usually have a streaky,multi-colored appearance. Clean the electrodeif it is fouled or scaled. See Section 15,Maintenance, for sensor cleaning procedures.

Reference junctionInspect the reference junction (the areabetween the sensor body and measuringelectrode) for heavy foulants or scaling. Iffoulants or hardness scales are present,remove foreign material using the proceduresdescribed in Section 15, Maintenance.

When mechanically cleaning the sensor, alwaysuse a soft bristle brush in order to avoiddamaging the insulating coating on thesolution ground (i.e., the metallic collararound the measuring electrode if present).This coating is only present on the outerdiameter next to the reference junction andmust be intact for the reference diagnosticsto function properly.

I-E67-84-1B February,2002 14-7

If the junction (especially a wood junction)has been attacked by the process chemicals,contact ABB for alternate junction materials.

Solution ground and O-ring sealsOn TBX Advantage sensors, inspect the solutionground (i.e., the metallic collar around themeasuring electrode if present) and sealing O-rings for attack by the process liquid. Ifthe solution ground shows evidence ofcorrosion or deterioration and/or the O-ringsappear distorted or swollen, contact ABB foralternate material choices.

Sensor Electronic Test

The pH/ORP/pION sensor can be electronicallytested to verify the integrity of the sensorelements and cable. These tests require aDigital Multimeter (DMM) that has aconductance function capable of measuring from0 to 200 nS.

The sensor leads and automatic temperaturecompensator leads must be disconnected fromthe analyzer before these tests can beperformed. Also the sensor must be placed ina container of water or buffer solution. Ifthe sensor is a standard ABB sensor (i.e.,TB5) which does not have a solution ground andhas a BNC, the center conductor will beequivalent to the blue lead (i.e., Sense) andthe shell will be equivalent to the black lead(i.e., Reference). Check the sensor using thefollowing procedure.

I-E67-84-1B February,2002 14-9

5. Check the conductance of the sensormeasurement electrode by measuring across theblue and green leads. The conductance must be1 to 10 nS when the sensor and solution incontact with the sensor is at 25 C. (If theo

sensor and solution are above or below 25 C,o

the conductance value can be estimated as one-half the conductance for every eight degreesabove 25 C or double the conductance for everyo

eight degrees below 25 C.)o

6. Check the voltage of the sensor referenceelectrode by measuring across the black leadfor the sensor under test and the black leadof a known good sensor. For this test, thesensor under test must be removed from theprocess and placed into a buffer solution.The known good sensor must also be placed inthe same buffer solution. The voltage must bebetween -180 mV and +180 mV.

Cleaning the Sensor

ABB pH/ORP/pION sensors are cleaned using oneor a combination of the following methods.These are recommendations and may not besuitable for all applications. Other cleaningmethods may be developed that better suitparticular applications. When cleaning,observe all safety precautions required forhandling chemicals. When handling chemicals,always use gloves, eye protection, safetyshield, and similar protective items, andconsult Material Safety Data Sheets.

WARNING Consider the material compatibility betweencleaning fluids and process liquids.Incompatible fluids can react with each othercausing injury to personnel and equipmentdamage.

WARNING Use solvents only in well ventilated areas.Avoid prolonged or repeated breathing ofvapors or contact with skin. Solvents cancause nausea, dizziness, and skin irritation.In some cases, overexposure to solvents hascaused nerve and brain damage. Solvents areflammable - do not use near extreme heat oropen flame.

Acid Dip Dip the tip of the sensor into a one to fivepercent hydrochloric acid (HCl) solution untilthis region is free of the unwanted coating.Minimize expose of any metal on the sensor, ifpresent, to this cleaning solution. Corrosionmay occur. This method removes scales fromwater hardness. After dipping, rinse sensorwith water.

I-E67-84-1B February,2002 15-3

Solvent Dip Dip the sensor into a solvent such asisopropyl alcohol. Remove solvent using aclean cloth. Do not use solvents which areknown to be incompatible with the plastic ofthe sensor. This method removes organiccoatings. After dipping, rinse sensor withwater.

Physical Cleaning Use a rag, acid brush, or tooth brush toremove especially thick scales andaccumulations. Take caution in cleaning theglass pH electrode, if present, to preventglass breakage.

When mechanically cleaning the sensor, alwaysuse a soft bristle brush in order to avoiddamaging the insulating coating on thesolution ground (i.e., the metallic collararound the measuring electrode if present).This coating is only present on the outerdiameter next to the reference junction andmust be intact for the reference diagnosticsto function properly.

after applying the factory andprocess calibration values.

For example, solution coefficients for purewater applications are:

Pure Water = +0.18 pH/10 Co

Pure Water w/ 1ppm Ammonia = +0.31 pH/10 Co

For the TB84PH Advantage Series analyzer, thesolution coefficient will either add (+) orsubtract (-) a configured amount of theprocess variable per 10 C to the Nernstiano

compensated process variable. Thus, anapplication having a process liquid thatdecreases in its pH value as the temperatureincreases should use a positive (+) solutioncoefficient correction factor. Conversely, anapplication having a process liquid thatincreases in its pH value as the temperatureincreases should use a negative (-) solutioncoefficient correction factor. For ORP andpION analyzer types, the solution coefficientadjusts the uncompensated process variable anddoes not use the Nerstian relationship.
